(a) Nineteenth and Forty-first Divisions arrive and form junc-
tion on Obey Support at 0.15.
(b) Nineteenth Division arrives Obstruction Avenue at 0.35
and halts there for half an hour.
(0) Forty-first Division advances from Oasis Lane at

pied portion of Obstruction Avenue under fire during the half an
hour’s halt in order to assist the advance of the Forty-first Divi-
sion.
(c) Nineteenth Division advances at 1.05.
(f) Nineteenth Division reaches Cateau Farm at 1.40.
(g) Forty-first Division reaches Dome House at 1.40.
16 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
(h) Nineteenth and Forty-first Divisions advance at 3.40 and
form junction at Bondulle Farm (inclusive to Forty-first Divi-
sion) at 4.10. '
(i) Nineteenth and Forty—first Divisions advance at 4.40 from
Bondulle Farm and form a junction at house 015055.95, in-
clusive to Forty-first Division, at Zero plus 5 hours.
27. .Divisional commanders will issue such orders as will
insure that all ranks under their command thoroughly under-
stand that the rifle and bayonet are the first weapons of the
Infantry soldier, and that they have not been replaced by the
bomb. Experience in the recent fighting has shown the necessity
of constantly impressing this fact on both oflicers and men.
28. In order to demoralize the enemy and at the same time to
increase the morale of our own troops, frequent raids will be
carried out on the corps front up to and including the night
before Zero (night Y/Z). The nature and size of the raids
will be determined by divisional commanders who will arrange
for any heavy artillery support they may require in direct com-
munication with the brigadier general commanding corps heavy
artillery. Every battalion should carry out one or more raids
during each tour in the trenches in order to insure that the
majority of the men in the battalion have been into the German
lines before the day of attack.
29. In order to prevent the enemy from finding out that our
troops are assembling for the attack, German patrols must be
kept at a distance from our lines on the night prior to Zero
(night Y/Z). Divisions will arrange for a screen of outposts
to be kept in close touch with the German lines until assembly
is complete.
To accustom the enemy to this form of outpost work screens
of this nature will be put out from dark to dawn during the week
preceding night of Y/Z.
30. There will be a conference of all intelligence officers in
Ninth Corps on Tuesdays, Thursdays, and Saturdays at corps
headquarters at 6 p. m. At this meeting all intelligence will be
pooled in order that information obtained may be disseminated
to all units.
31. The Eleventh Division will detail one battalion for perma-
nent work on communications before and during operations. The
AD. Signals will work out schemes and will arrange the neces-
sary details in direct communication with the officer commanding
this battalion. Eleventh Division will notify Ninth Corps and
AD. Signals of the battalion detailed.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 17
32. From now onward the systematic destruction of the
enemy defense system will begin. Special targets, such as sig-
nal stations, observation posts, headquarters, etc., which have
hitherto been saved up, will be destroyed in turn. Some of these
targets may take days to destroy, and 1f the work is not taken
in hand at once it may be found at the last moment that many
of them have not received sufficient attention necessary to put
them out of action. '
II. May 15, 1917.
33. In making reference, to times before or after which opera-
tions will commence, the following nomenclature will be adopted
in future:
(a) Referring to days—Z day is the day on which operations
take place.
One day before Z = Y day.
Two days before Z = X day.
Three days before Z = W day.
Four days before Z = V day. “
Five days before Z = U day.
Days before U day will be referred to as Z—(i, Z——7,
Z——~8, etc.
One day after Z = A day.
Two days after Z = B day.
Three days after Z = C day. ,
Days after C day will be referred to as Z+4, Z+5,
Z—l—G, etc.
(b) Referring to hours on Z (Zap—Zero is the exact time at
which operations will commence, and times will be designated in
hours and minutes + or —- from Zero, even if they encroach on
Y day.
34. The pioneer battalion of the Eleventh Division is placed at
the disposal of the chief engineer for work in connection with
trench tramways. The chief engineer will prepare the forward
scheme in consultation with the divisional commander and will
arrange the necessary details for reconnaissance, etc., in con-
junction with the oflicer commanding the pioneer battalion.
35. The strictest orders will be issued by divisional com-
manders to insure that no marked maps of any description of
our own lines are allowed to be taken by any oflicer, N.C.O.,
or man in advance of battalion headquarters.
10049°—17———2
18 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
36. Divisions will reconnoitre and prepare tracks for the move-
ment of troops across country. These tracks will be marked with
signboards and be brought into use by troops as soon as prepared.
37. In order to prevent leakage of. information and to insure
that other methods of communication are practiced, all com~
munication by telephone and messages sent on buzzer will cease
in advance of present battalion headquarters until the hour of
Zero. The telephones which may be used by corps and divi-
sional signal companies and army area parties will be exempt.
The following methods of communication will be permitted
in front of battalion headquarters:
Pigeons.
Visual.
Runners.
Fullerphone for SOS calls.
Rockets for SOS calls.
N. B.-—All Fuller-phones in front of battalion headquarters
. will either be issued without hand sets or have the microphones
removed from the speaking circuits.
The method of communication between brigade and battalion
headquarters is left to the discretion of divisional headquarters.
Existing SOS lines, battery to company, with the exception of
buried lines, will be recovered, and the batteries connected to
battalion headquarters only. These lines must be recovered to
save cable and lessen the probability of messages being carried
forward by induction. In cases where the retention of these
lines is desired by the artillery for observation purposes, special
sanction for their retention will be given by divisional com-
manders.
The necessary orders to insure that no message is sent by
pigeon which contains anything in the address “ to” or “from ”
or body of message, which would be of value if it fell into the
hands of the enemy, until after Zero hour. .
38. Reference S. S. 135, Section XXX. The numbers therein
laid down will be left behind when the unit goes into the attack.
They should be accommodated with the first-line transport and
will rejoin their units when they come out of the line. It is,
however, left to the discretion of divisional commanders to send
forward any oflicers or men should they consider it necessary to
do so in order to maintain the efliciency of any particular unit.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 19
III. May 20, 1917.
39. In making references to times before and after which
operations will take place, the symbols + and —— will not be
used, but the words “ plus” or “ minus ” will be written in full.
In referring to times before or after Zero hour the words
“ Zero plus ———— ” or “ Zero minus ” will be inserted to pre-
vent possible confusion with clock times.
40. The provisions laid down in Instructions for the Training
of Divisions for Offensive Action, page 60, Section XXXII,
will be carried out. 7
41. Divisional commanders are reminded of the necessity of
impressing upon all ranks under their command that it is of the
utmost importance to keep divisional headquarters constantly
informed of the state of affairs, in order that higher authority
may be informed and arrangements made in time to take
advantage of success as well as to give eflicient support.
42. The necessity of pushing forward to their objective, re-
gardless of the progress of units on either flank, must be
impressed on all ranks. It should also be made known to them
that the care of the wounded is not in their province, as special
people are detailed for this purpose.
43. All men should be warned against the probable misuse of
white flags and signs of surrender by the enemy. They have also
been known to sham death and then to shoot into the back of
our assault. '
The possibility of the enemy using ruses, such as giving the
order “ retire,” must be impressed upon all ranks.
44. All commanders down to platoon commanders will keep
in touch throughout with the commander of the similar forma-
tion on his flanks. They must know the dispositions and action

_ being taken by their neighbors, and the more particularly so
when the units on the flanks belong to another division.
45. Watches will be synchronized at 12 noon daily from June 1
under arrangements to be made by the signal service.
46. Infantry OfllCCl‘S will be detailed to watch and report on
the progress of wire cutting. It will be the business of those
oflicers to arrange for reconnaissance of the wire by night
and report the result next morning to the Royal Artillery.
Arrangements will be made by the Royal Artillery and Infan-
try, by gun and machine-gun fire, to prevent the enemy from
repairing his wire during the night.
2O NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
To enable patrols to examine the enemy’s wire and raids to be
carried out, there will be no fire on the enemy’s front line be-
tween the hours named below:
Night V/ W, 11 p. m. to 12 midnight.
Night W/X, 10.30 p. m. to 11.30 p. m.
Night X/Y, 12 midnight to 1 a. m.
Night Y/Z, 11.30- p. m. to 12.30 a. 111.
IV. May 21, 1917.
47 . The following roads in forward area are allotted to divi-
sions: ' .
Thirty-sixth Division—‘Daylight Corner—Wulverghem
Diversion—Kruisstraat Cab-
aret.
Lindenhoek—Store Farm.
Sixteenth Division—Hemmel-Wytschaete V.
C. Road.
Nineteenth Division—Vierstraat—Wytschaete.
Brasserie—Grand Bois.
448. Each division will select a cross-country route from the"
vicinity of Wytschaete back to our own area for the use of
empty vehicles.
(a) Within our own lines trenches will be bridged and routes
marked with posts. Bridges and marking posts required within
the enemy area will be dumped at some convenient place in our
forward trenches. Concealment is of first consideration.
Bridges must be strong enough to carry motor ambulances, guns,
or loaded wagons. Spare material for repairs will be dumped
near each bridge in case it is broken by shell fire.
(b) Batteries detailed to move forward to'new positions in
“ No Man’s Land ” should, if possible, use the routes mentioned
in (a). If these are not suitable, other routes will be recon-
noitered and similarly prepared. _
(c) All batteries must be prepared to advance over the Ger-
man trenches without assistance from othertroops when once
the advance is ordered. For this purpose arrangements will be
made for them to carry special portable bridges.
49. Twenty-five portable artillery bridges will be issued to
divisions when received. These bridges will be used for opera—
tions, but a proportion may be used at the discretion of divisional
commanders for cross-country tracks previous to operations. No
further allotment beyond 25 per division can be looked for.
mm cones msmucmions FOR THE ormmsrvn. 21
50. Boards with the names of farms and the direction of cer-
tain main roads are being prepared by C. E., Ninth Corps. Divi-
sions will arrange for them to be put up after each locality has
been captured.
51, (a) The army commander has decided to extend the scope
of operations already ordered, and his intention is that the
troops of the Second Army should, after taking the black line,
push forward and establish themselves on the line Owl support
trench—Odyssey trench.
(b) The new objective will be known as the Oosttaverne line
(called also green line by the Second Army), and is subdivided
between corps as follows: -

Second Anzac Corps ____ _-River Douve—O.28.b.5.2.
Ninth Corps lO.28.b.5.2—O.16.c.4.2.
Tenth Corps 0.16.042, via Olive trench, to black
line.
(0) The black line, which should be completely in our hands
by Zero plus 5, will be consolidated without delay with every
available man. The Oosttaverne line will be subjected to a
heavy bombardment from Zero plus 5 hours until the approach
of the attacking infantry, and a number of field guns will be
brought forward into previously selected positions.
(d) The ‘Tenth Corps will at New Zero advance with troops
of their reserve division from the black to the Oosttaverne line,
preceded by a barrage. The Ninth and Second Anzac Corps
will’, after the capture of the black line, push forward patrols,
and, if possible, mounted troops within the limits of the areas
assigned to them, and will arrange that at New Zero they ad-
vance preceded by a barrage from the junction of the Tenth and
Ninth Corps on the black line and approximately the line
0.27, central—Despagne Farm—White Spot Cottage to Oostta-
verne line.
(6) In the case of the Ninth Corps the advance will be carried
out by the troops of the reserve division of that corps, and in the
case of the Second Anzac Corps by troops which have not been
employed in the capture of the black line.
( 1‘) No attempt will be made to relieve the troops on the Cost-
taverne line on the night Z/ A.
(g) All available tanks will assist in the advance.
(h) Any enemy guns between the black line and the Oostta-
verne line will be prepared for destruction and the gun teams
dealt with in the proper manner.
22 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
52. The movements of the Ninth Corps to the attack of the
Oosttaverne line from O.28.b.5.2 to O.16.c.4.2 will be as follows
(these movements have been coordinated with the movements
of the corps on either flank) :
(a) When the barrage lifts off the black line at varying times
from Zero plus 4.10 on the right to Zero plus 5 on the left, it will
move 300 yards forward and join with the barrage of the Second
Anzac Corps at farm O.26.d.8.8 and with that of the Tenth Corps
at O.15.d.1.7.
(b) Divisions will push out their patrols as far as the barrage
permits and ofiicers’ patrols from the corps cavalry will assemble
under cover of the western slopes of the Wytschaete-Messines
Ridge.
(0) At Zero plus 5.30 the barrage will creep forward at the
rate of 100 yards every three minutes and pile up on the line
road junction O.27.d.6.9—O.21—central-O.15.d.1.7 until plus 6.30,
when it will cease unless recalled by the SOS signal.
((1) At Zero plus 5.30 cavalry patrols will move forward within
the limits of the barrage and divisions will push‘ forward strong
patrols, which will establish themselves in strong points on the
line farm 0.27 .d.2.9—railway junction O.21.c.6.1—oil trench-eastern
side of Oosttaverne wood.
This line will be known as the Mauve line, and is subdivided
as follows:
Thirty-sixth Division—Farm 0.27 .d.2.9-Railway junction
O.21.c.6.1. .
Sixteenth Division—Railway junction O.21.c.6.1—Junction
railway and oil trench O.21.a.2.8.
Nineteenth Division—Junction railway and oil trench
O.21.a.2.8—Black line O.15.c.55.95.
(6) At New Zero minus 15 minutes the barrage will form up
again on the line O.27.d.6.9-O.21 central—01560.7.
(f) By New Zero a brigade of the Eleventh Division (corps
reserve) will, having deployed behind the line of strong points
‘on the Mauve line, he closed up to the barrage ready to advance
to the attack of the Oosttaverne line. This brigade and one field
company are placed under the orders of the G. O. C., Sixteenth
Division, for the purpose.
(g) At New Zero the barrage followed by the infantry will
creep forward at the rate of 100 yards every three minutes and
will pile up on Odious-Odour-Odonto trenches. Under cover of
this advance the Corps Cavalry Regiment, Ninth Cyclist Batta-
lion, and Nineteenth Motor Machine Gun Battery, should the
NINTH soars INSTRUCTIONS FOR THE orrnnsrvs. 23
previous reconnaissance prove the ground suitable, will move
forward to positions of assembly east of the Wytschaete-Messines
Ridge.
(h) At New Zero plus 20 minutes barrage lifts onto the sup-
port trench.
At New Zero plus 35 minutes barrage lifts from support trench
and forms protective barrage 300 yards to the east of it.
(t) The line captured will be consolidated and prepared to
resist counter attacks, and will be reinforced after dark if neces-
sary.
(j) At New Zero plus one hour five minutes the barrage
ceases and,‘ if opportunity offers, cavalry patrols will be pushed
through to reconnoiter and prepare the way for the corps
mounted troops.
(h) For the purpose of keeping direction and being in close
touch with the corps on either flank the following houses or
farms on the boundary will be objectives for both corps:
BET‘WEEN NINTH AND SECOND ANZAC CORPS. .
Lumms farm _________ -- Consolidated by Ninth Corps.
Farm O.26.d.8.8________ Do.

Farm O.15.d.7.5 _______ ___ Consolidated by Tenth Corps.
Farm O.16.c.4.2________- Do.
(1) G. O. C., Nineteeth and Thirty-sixth Divisions will give
G. O. C., Sixteenth Division, every facility for assembly in and
passage through their areas of the above-mentioned brigade of
the Eleventh Division, and any such other troops as G. O. C.,
Sixteenth Division, may consider necessary to move forward.
53. (at) Tanks have been allotted as follows:


Second Anzac Corps 5 sections.
Ninth Corps 4 sections.
Tenth Corps 3 sections.
Army reserve 6 sections.
Total ___ 72 tanks.

24 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
(b) The tanks allotted to Ninth Corps will be‘employed as
follows: ‘
For advance from blue to black line:
Nineteenth Division, 1 section, Northern Tank Battalion.
Sixteenth Division, 1 section, northern Tank Battalion.
Thirty-sixth Division, 1 section, Southern Tank Bat-
talion.
Corps Reserves, 1 section, Northern Tank Battalion.
For advance from black to Oosttaverne line:
Sixteenth Division—3 sections from Army Reserve.
1 section from Corps Reserve.
\ Any others which'can be rallied.
(o) The commander, Second Heavy Brigade, has instructed
battalion.commanders to get into touch with divisional com-
manders concerned in order to ascertain. their wishes’ and ar-
range ‘necessary details with regard to the tanks allotted to
them. /_ ‘
(d) It must be impressed on every infantryman that the
tanks are ‘there to assist his advance if possible, but that he
must never for a moment suppose that success‘depends on their
presence. The men must never wait for the tank but must push
on to their objective irrespective of whether they come up or
not. There is a great danger of the attack being held up if
this is not thoroughly realized by all ranks.
V. May 22, 1917.
54. In order to avoid casualties, the whole of the infantry of
leading infantry brigades should get rapidly across “ No Man’s
Land,” and as few troops as possible will be left in our own front
and support lines.
55. Divisions will be responsible that all preparations are‘
made to facilitate the advance of the infantry through our front
system of trenches, by the provision of bridges and ladders and
the removal of wire in front and support lines where necessary,
due regard being paid to the concealment of this from the enemy
until the last moment.
56. In the event of any division or brigade being help up, the
units on the flanks will on no account check their advance but
will form defensive flanks in that direction and press forward
themselves so as to envelop the strong point or center of re-
sistance which is preventing the advance. With this object in
view reserves will be pushed in behind those portions of the
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 25
line that are successful rather than those which are being
held up.
57. In order to assist the artillery in locating their own in-
fantry, each division should carry flags on a scale of not less
than two per platoon. Strict orders will be issued that flags
are not to be stuck in the ground in order to avoid mistakes
which might be caused by flags left behind in evacuated posi-
tions. '
58. The SOS signal will remain red signal cartridges as at
present. Green 1-inch and 15-inch signal cartridges will be kept
in reserve for use should it become necessary to make a change.
Corps reserve of flares No. 2 green has been increased to 14,000.
The table attached to Appendix V should be amended accordingly.
VI. May 25, 1917.
59. In order to, as far as possible, keep the date and hour of
Zero secret, all recipients of “Ninth Corps Instructions for the
Offensive ” will, when issuing their orders regarding any opera-
tions, give the actual date on which they will take place and not
refer to that date as “U day,” “ V day,” etc., or “ Zero plus +
or minus —.”
60. Instructions will be issued to prevent telescopic rifles being
taken forward in the attack. They will be kept back for use
later when required.
61. To prevent congestion of ordinary traflic during the move-
ment of troops battalions and batteries will march at intervals
of 500 yards, and brigades at intervals of 1 mile.
62. It is most important that every precaution should be taken
to prevent bayonets flashing in the moonlight, should there be a
moon, when units are moving to their positions of assembly.
63. Instructions will be issued by divisions that, in the event of
hostile aeroplanes flying low over our lines, to ascertain whether
our trenches are more strongly manned than usual, all ranks will
remain still and will not look up.
Arrangements will be made by divisions for antiaircraft ma-
chine guns to deal with such planes.
VII. May 27, 1917.
64. By midnight May 31—June 1 the system of communica-
tions which will be used for operations is to be completed and
ready for use. A proportion of the personnel which will work
26 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
the system during operations will move into each officeby this
hour.
In the case of formations, the headquarters of which do not
move into their battle positions until later, the existing com-
munications will be so rearranged by this hour that the mini-
mum amount of change will be necessary to bring their corn—
munications onto a battle footing when headquarters finally move
forward. '
When consolidating the lines ordered in paragraph 25, and
any further lines which it may be decided are to be consolidated,
special attention is to be paid to wiring. It must be impressed
upon all ranks that good wire sited at a suitable distance will
make certain the defeat of the strongest hostile counter attack,
and that comparatively weak counter attacks have a good chance
of succeeding against an unwired position.
Arangements must be carefully thought out beforehand for
bringing up the necessary supplies of wire to the positions to be
consolidated as soon as possible.
VIII. May 31, 1917.
66. Reference instruction No. 4 (f). The bombardment will
be of five days’ duration begining to-day, May 31, and will be
followed by two days’ intense counter battery work.
With a view to drawing the enemy’s fire and making him dis-
close the positions of his guns, practice barrages on the whole
corps front (with overlap into areas of corps on either flank)
will be carried out on the 1st and 3d of June.
On the 3d or 4th of June a practice barrage will take place
along the whole army front. Smoke shell will be used in all
practice barrages. _
Detailed orders with regard to the above will be issued by
G. O. C. R. A. Ninth Corps.
Smoke candles will be used should the wind be favorable.
Divisions will arrange to have candles in position——-two candles
for every 10 yards of front—and for lighting them at the hour
fixed for the barrage to begin.
67. Balloons on Ninth Corps front will be situated as follows:
M30628.
S.6.b.7.2.
N.33.a.5.1 (not rising before Z day).

69. It has been‘decided that the policy to be ‘observed in deal~
ing with hostile guns west of the Oosttaverne line will be as
follows: _
Enemy guns which may be of use to us will be saved. The
gun teams should be killed, and the breach mechanism with any
removable sight removed if necessary. Destruction by exploQ
sives is not to be resorted to unless it is evident that the Cost-
taverne line can not be gained and held. In this case the officer
on the spot must use his own judgment as to destroying the guns.
Explosives for this purpose will be taken forward.
Breach blocks and sights removed from the guns will be re-
tained near the guns by the parties who remain in charge of
them until it becomes evident that no use can be made of the
gunsby us, in which case parts removed will be carried back
to battalion headquarters or destroyed. ’
R. A. personnel is to be told off ready to be sent up to man the
guns if required. .
70. The SOS signal is a RED signal cartridge. It must be im-
pressed upon all concerned that the signal is to be repeated
until our artillery open fire. ’

APPENDIX I.
MACHINE GUNS.
1. Machine guns allotted for covering fire will be divided into
three categories .:
(a) Guns to establish a creeping barrage either direct, enfllade,
‘or oblique in front of the artillery barrage. The object of this
barrage is to catch anyone rushing back from the heavies or
sheltering in shell holes or ditches between the trenches.
(1)) Guns detailed for fire on selected targets, such as strong
points, cuttings, or ravines. '
(0) Guns to sweep all ground in front and rear of enemy’s
main line of resistance from the commencement of the attack.
2. Guns for (a) and (b) will be more or less on a line about
1,000 yards behind our front line.
Guns for (0) will be on a line as far forward as possible so
as to obviate a change of position before the ridge is secured.
3.. Guns for covering fire are allotted to divisions as under—
Thirty-sixth Division : _ Guns.

5. Divisions will be responsible for distribution of fire over
the Zones allotted to them in paragraph 4 above in accordance
with the principles laid down in paragraph 1 (a), (b), and (c),
for the selection and preparation of positions and for details of
lifts.
The guns in each divisional sector will be under the control of
the division with the proviso that the barrage guns or their
tasks, once approved, will not be altered without the authority
of the corps. ,
6. Guns told off to form the creeping machine-gun barrage
will lift in conformity with the creeping artillery barrage. The
line of the lowest bullets of the machine-gun barrage will be 200
yards in front of the artillery barrage line.

8. From now onward to Zero day fire will be carried out on
communication trenches and paths used for supplies, dumps, and
headquarters with their approaches, trench-mortar emplacements
with tramways and tracks used for bringing up ammunition.
9. It is hoped that two spare barrels will be available for each
gun. Care will be taken that the harassing fire laid down in
paragraph 8 will be regulated so that undue strain is not placed
upon personnel and materiel at an early stage which might lead
to a lessening of the intensity of fire just before Zero day.
10. Guns will be grouped under arrangements to be made by
divisions in consultation with Ninth Corps machine-gun oflicer.
Divisions will appoint an officer to control the groups of guns
on the divisional front.
11. Second Anzac Corps zone of fire overlaps to the north of
Ninth Corps southern boundary of attack by 50 yards.
Second Anzac Corps is paying special attention to keeping
Enfer Wood under machine-gun fire.
Tenth Corps zone of fire overlaps to the south of the northern
boundary of the zone of fire of Nineteenth Division by 50 yards.
12. Six guns (eight in the case of the left division) are avail—
able with each attacking brigade to assist in covering, consoli-
dation, and to repel counter attacks.
13. Machine guns for the protective barrage to cover the con—
solidation of the black line will be in position by Zero plus 5.30,

The barrage lines and approximate positions are shown on
map G6.
14. One section of each group will be in position to search the
ground between the first and second barrage lines as soon as pos-
sible after the capture of the black line, and later to cover the
advance to the Oosttaverne line.
At Zero plus 5.30 those groups, except the Hospice and Mar-
ten’s farm groups, will lift off the first barrage line and search
forward to the second barrage line on which fire will be main-
tained until Zero plus 9.50 (new Zero minus 0.10). At this
hour they will lift 200 yards and at Zero plus 10 hours (new
Zero) will cease fire.
The Hospice group will conform to the above until Zero plus
6.30, when it will be held in readiness to advance.
The Martens farm group will, at new Zero minus 0.10, lift
off its first barrage line and creep forward to its second line,
where it will cease fire at new Zero and lift to the road from
O.17.c.00.30 to O.23.a.10.25. It will cease fire at new Zero plus
one hour.
On completion of the tasks the above groups will not be fur-
ther required.
15. Machine-gun companies as under will concentrate and will
be at the disposal of the G. O. C., Sixteenth Division, for oper-
ations against the Oosttaverne line: -

notified of the dates on which preparations for attacks under
(0), (0),, and (6) above in each division will be complete, and
will issue orders for the date and hour at which the attack will
take place.
6. K and 0 Special Companies will withdraw from the trenches
as soon as the attack on X/Y night is completed, leaving the
front-line system clear for infantry. ,
7. A map showing localities where German dugouts are known
to exist and where the enemy are reported to live has been issued
to Capt. Wight.
APPENDIX III.
' MINES.
A. NOTES IN CONNECTION \VITI-I THE FIRING OF hIINES.
The material thrown up by a large mine rises steadily like.
a gigantic button mushroom until the pressure is great enough
to break through the surface skin, when flashes of flame and
smoke appear and a certain amountof debris is projected up-
ward, the bulk opening outward and falling to form the lip
- of the crater.
The debris falls comparatively close to the crater, and al-
though some lumps may be thrown as far as 150 yards, a dis-
tance of 200 yards from the center of the mine may be con-
‘ sidered safe. All material comes down within 20 seconds.
In addition to taking precautions from falling debris, damage
to trenches and dugouts, both surface and tunneled, by earth
shock may occur. For this reason the troops assembling at
the 200-yard line should lie down on the ground behind ‘the
par/ratios well clear of any parapets or structures that might
shake down. All surface dugouts andtrenches up to 300 yards
should be cleared, as the former may collapse and the latter
be shaken in, the troops lying down behind as for the 200-yard
line. -
Tunneled dugouts and subways up to 400 yards should be
vacated, any inside the 300-yard line being strutted as far as
possible. A certain amount of broken timber and falling dirt
underground may be expected. All paraflin and candle lights
and other naked lights should be extinguished before evacuation
of dugouts as a precaution against fire. Arrangements are
being made to supply a few portable electric lamps, which can
' be hung up at the foot of stairs and in galleries in each dugout.
These should not be used till just before evacuating the dugouts,
so as to insure light being available.
Proximity to old walls and buildings and damaged trees up
to 500 yards radius should be avoided.
It will be seen from the above that the attacking troops can
start 20 seconds after they feel the shock, as by the time they
36
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 37
A
have got up and have covered 50 yards ample time will have
elapsed for the debris to fall.
The bottoms of craters should not be entered on account of
the possible presence of gas. There may also be instances of
blue flame (carbon monoxide burning) in the bottoms. The
risk of the presence of gas is small but should be guarded
against. Any consolidation of lips of crators should be carried
on in the upper 10 feet of the lip. Instructions are being issued
to tunneling companies to arrange for proto men to be ready
at stations on their front in case of gassing of men.
Danger areas should be marked beforehand. A method is
suggested in instructions (B). .
The tunneling ofiicer charged with the firing of any mine will
synchronize his watch with the infantry oflicer commanding
the assembled troops,'who have to move over the area aifected
by the mine. If a mine has not exploded within 10 seconds of
Zero it may be taken that the mine will not be fired at all.
B. INSTRUCTIONS TO TROOPS IN CONNECTION WITH THE FIRING OF
LARGE LIINES.
1. When a mine is fired a certain area has to be kept clear
on account of—
(1) Falling debris.
(2) Earth shakes.
1. Accommodation is to be found for from three to five tun-
safe. All debris falls inside 20 seconds of firing. (See paragraph
3 for precautions to be taken between 200 and 300 yards radius.)
3. As regards earth shakes—
(1) Vacate all surface dugouts and trenches within a radius
of 300 yards from the mine, the men lying down behind the
parados well clear of (my parapets 01‘ structures that might
collapse.
(2) Vacate. all tunneled dugouts and subways within a radius
of 400 yards at the moment of fire, all tunneled dugouts within
a radius of 300 yards being strutted if possible. Extinguish all
oil lamps and candles before vacating dugouts to preventrisk
of fire. '
(3) Keep clear of old brick walls and buildings and trees
with damaged trunks and branches up to a distance of 500 yards
from the mine.
4. Indication posts marking the 200 and 300-yard lines are to
be put up. They should be. easily distinguishable in the dark.
38 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
Posts in pairs at the 200-yard line and in threes at the 300-yard
line are suggested. A tape could be run out during the last
night.
5. After a crater is formed do not go into the bottom. Any
necessary consolidation should take place in the upper 10 feet
of the lip.
6. Apply to the tunneling company in your area as to- where
the nearest station of proto men is, so as to be able to obtain
assistance in case any men are gassed.
7. If a mine has not exploded within 10 seconds of Zero, it
may be taken that this mine will not be fired at all.
C. INSTRUCTIONS AS TO THE IVIAINTENANCE AND REPAIR OF TUN-
NELED DUGOUTS AND SUBl/VAYS.
1. Accommodation is to be found for from three to five tun-
nelers in each brigade headquarters or equal-sized dugouts for
maintenance.
The duties of these tunnelers are——
(a) Repairs underground and to entrances;
(1;) Maintenance of pumps, but not pumping.
The latter should be done by the infantry.
2. Subway paraffin lamps are being supplied; a lamp man will
have to be appointed.
3. A pick and shovel are to be hung upon the wall at the foot
of inclines and Stairways.
4. Permanent police should be detailed to each subway. They
should take up their duties some days before operations so as
to be fully acquainted with their duties and with the plan of
the system. - ‘
5. Direction boards are to be put up in subways.

ORDER OF BATTLE.
The Nineteenth (Saxon) Corps, consisting of the Second (Prus-
sian), Twenty-fourth, and Fortieth Divisions, are at present
holding the line opposite the corps front. The Second Division
are in the line to the north and the Fortieth Division to the
south, with the Twenty-fourth Division in reserve in Renaix.
The order of battle of regiments north to south at present is
believed to be—
Fourth Grenadier Regiment
Forty~fourth I. R. Second Division.
Thirty-third Fusillier Regiment
One hundred and fourth I. R.
One hundred and eighty-first I. R. Fortieth Division.
One hundred and thirty-fourth I. R.
HISTORY OF NINETEENTH CORPS.
At the beginning of the war the Nineteenth Corps formed part
of the Third German Army under Gen. von Hansen, which ad-
39
40 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
vanced through the Ardennes and took part in the Battle of
Dinant. In the outflanking race northward at the end of
October, the Nineteenth Corps was transferred to the Sixth
Army under the Crown Prince of Bavaria. This corps was
driven back by our cavalry in October, 1914, to the Ploegsteert—
Bois Grenier sector, where it remained until August, 1916, when
it left for the Somme. The Nineteenth Corps came into its
present sector in October, 1916.
The Second (Prussian) Division was on the Russian front
from the outbreak of war until January of this year. This
division made its first appearance on the western front in March,
when it was identified in the Spanbroek sector, now held by
the Fortieth Division. The Second Division was relieved by
the Fortieth Division about the middle of April and in turn a
few days later relieved the Twenty-fourth Division and came
into its present sector.
MORALE.
The morale of the Twenty-fourth and Fortieth Divisions. is
good. There have been no cases of desertion. These two divi-
sions have not had any serious losses since leaving the Somme
and are probably seasoned and good fighting troops.
The morale of the Second Division is probably poor. There
have been several cases of desertion, and the morale of prisoners
captured has not been good.
IMETI-IOD OF HOLDING THE LINE.
Each division in the line has one battalion in front line and
supports, one battalion in reserve, and one battalion in rest
billets. The rest billets for the Nineteenth Corps are in Comines
and in huts on the outskirts of the town.
The exact distribution of the resting battalions in case of at-
tack is not known, but it is probable that these battalions will
occupy the double line of trenches west of the Messines-
VVytschaete Road, strengthen the garrison at the Wytschaete de-
fenses, and occupy the double line of trenches running northeast
from Wytschaete through squares~28.0.l4.c. and d.0.15.a..
An approximate estimate of the strength of the enemy’s avail-
able forces at present on the Ninth Corps front is 0.9 man
per yard, organized in depth. Under present organization about
70 machine guns should be available, exclusive of the new light
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 41
machine gun. It is not known whether the light machine guns
have been issued to the Nineteenth Corps. From the statements
of prisoners who have been captured during the recent opera-
tions to the south, it appears that an issue of one light machine
gun per platoon (three per company) is the normal scale.
B. ASSEMBLY POSITIONS AND APPROACHES FOR REINFORCE-
MENTS.
Oosttaverne Wood and the ground in squares 0.20 and 0.21 are
invisible from the ground observation posts. Practically the
whole of the Oosttaverne line is invisible from Kemmel.
The Oosttaverne line is probably invisible from the top of
the Messines-Wytschaete Ridge, except possibly from houses in
Wytschaete.
The-Ypres-Comines Canal is a serious obstacle to the enemy in
moving troops forward for counter attack or for reinforcements.
Numerous footbridges have been built across the canal, but the
main points of crossing are at Comines and Houthem.
The country is much intersected by hedges and ditches, and
the movement of large formed bodies across country would not
be an easy matter.
The roads normally used by reliefs are shown on map'G4.
The valleys of the streams Roozebeek, Wambeek, and Blauwe—
poortbeek would probably give a certain amount of cover to
troops supplied with guides knowing the country and are likely
approaches to points of assembly prior to counter attack.
The normal time taken by troops marching from Comines to
Wytschaete is two and a half hours.
C. RAILWAYS AND SYSTEM OF SUPPLY.
The enemy’s routes and railways are as shown on attached
map.
The country in rear of the Wytschaete-Messines Ridge is in-
tersected by the Ypres-Comines Canal and the River Lys, form-
ing a triangle with Comines at the apex. -
Comines is the ammunition and supply railhead for the troops
opposite the Ninth Corps front. Rest billets for infantry and
pioneers are also in Comines.
All the used forward approaches, both railways and relief
routes therefore diverge from Comines.
42 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
RAILWAYS.
The railway station at Belgian Comines has had its buildings
destroyed by our bombardments. It is, however, still an impor-
tant transfer point from broad to meter gauge. The broad-gauge
line from Wervicq is no longer used for anything but the car-
riage of materiel and ammunition. Troops for this part of the
front use Wervicq as a detraining station. French Comines sta-
tion at V.5.c.97.55 is another transfer point from broad to meter
gauge. The broad-gauge line between Comines, France and Bel-'
gium, is no longer in use, the bridge at P.35.c.2.4 having been
destroyed and replaced by a pontoon which only carries a meter-
gauge line (an extension of the Halluin steam tram).
From Belgian Comines the Pioneer Dumps at I—Iouthem are fed,
and thence the front-line system south of the Ypres-Comines
Canal. . '
From French Comines station the meter-gauge railway crosses
the twin bridges at V.4 central and runs along the canal as far as
the lock in P.34.c, where a siding goes off toward the big supply
dump in P.34.d.
The broad-gauge lines from Quesnoy to Comines and Comines
to Warneton are known to be used, but only for transport of
ammunition and pioneer materiel. In connection with the latter
there is a main point of transfer from broad to meter gauge at
P.33.d.7 .6. Here pioneer material is transshipped into light rail-
way trucks and shunted into the big depot at P.34.d.4.5.
The forward routes from Comines are as shown on map G-4.
AMMUNITION SUPPLY.
Ammunition dumps are believed to exist in P.34.c and (1. Am-
munition is brought forward on meter-gauge railway to forward
dumps in O.25.d “ Cinema Dump.” From here it is brought di-
rect to the batteries on meter-gauge and light railways (60 cm.).
It therefore appears that the destruction of the bridge at V.4
central, the dumps at P.34.c. and d., and O.25.d. would seriously
interfere with the enemy’s ammunition supply.
SUPPLIES.
The supply railhead is Comines. Supplies are brought for-
ward largely on the railways, horsed and lorry transport being
little used. The normal routes followed by transport are as
shown on map for reliefs.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 43
PIONEER STORES.
. The main pioneer dump is at Houthem. Stores are brought
from Comines by rail along the east side of the canal to dumps
at P.20.a.05.7 and P.19.b.40._45.
Pioneer stores are entirely transported forward on the tram-
ways.
D. STEENEBEEK SECTOR.
N.36.a.70.30 to N.24.c.90.55 (regimental sector at present occupied by
One hundred and fourth Infantry Regiment, Fortieth Division).
FRONT-LIN E DEFEN SES.
1. The front line in this sector has been damaged to such an
extent by shell fire and trench mortars that the enemy has been
unable to effect the necessary repairs and has been compelled
to abandon considerable portions of it, at any rate temporarily.
The portions which he does hold are held only lightly, and
occupied dugouts are very rare.
Patrols at the end of February penetrated the front line in
N.36.a (Nathan trench) and found it unoccupied and partly
filled with wire. A patrol which entered the enemy’s trench
at the beginning of May at N.30.c.43.37 found an isolated sentry
group, but the trench generally unoccupied and blocked with
wire. '
Prisoners taken on January 22 whilst on patrol behind their
own front line, which at the time was untenable from N.30.c.-
13.70 to 18.60, stated that both front and support lines were
waterlogged and required continuous pumping.
A patrol which entered Narrow trench at N.30.c.10.70 on
March 1 found it in moderate condition, but blown in at several
places.
According to the latest prisoners’ statements,- the front line
of the Spanbroekmolen is lightly but not continuously held.
North of N.30.a.25.06 there are 120 yards of unoccupied trench,
and there is another unoccupied portion from N.30.c.10.65-
38.49. This part of the line is commanded by a machine gun,
which is at present kept in position during the night at N.30.c.-
40.43. There are two occupied dugouts, the first at N.30.c.10.99
and the second at N.30.c.08.89; the latter is a deep-mined dug-
out, with two entrances, and can hold about 30 men.
In N.24.c the trenches are in a very bad condition, and up to
the middle of April dugouts were full of water and uninhabit-

able, with the exception of two mined dugouts at N.24.c.82.25
and 85.55.
The enemy put a great deal of work into the lines in this
sector during the summer of 1916, and made the Spanbroekmolen
salient into a point of considerable strength. The destructive
fire of our trench mortars and artillery have deprived him of
the benefits he expected to derive from this work. His main
line of resistance is at present the reserve line, Nathan reserve,
Narrow reserve, and Naples reserve; the latest aeroplane photo-
graphs, however, show that Narrow reserve, which was sub-
jected to a heavy bombardment at the end of April, has been
abandoned, and the enemy is engaged on the construction of a
new trench immediately behind it. Naples support, which is in
moderate condition, is probably fairly strongly held, and there
are four occupied dugouts in Narrow support, about N.30.c.50.83,
one of which is used as a company headquarters.
The latest aeroplane photographs entirely confirm the state-
ments of prisoners and the reports of patrols that the trenches
in this sector are, as a whole, in very bad condition, and further
show that the enemy is making no organized effort to repair
them.
HEADQUARTERS AND TELEPHONE EXCHANGES.
2. Regimental headquarters are in two large dugouts at
O.34.b.21.23 and 27.15. Aeroplane photographs show these dug-
outs with signs of a large amount of movement in the neighbor-
‘hood, also traces of cables.
Two battalion headquarters are known, the one at Torreken
farm (O.20.d.15.30), used by the battalion in support, the other
at Goderis farm (O.25.b.20.25), used by the battalion in‘the
line, both these farms are connected by cables.
Bogaert farm (O.25.a.90.95) is the headquarters of the com-
pany in support to the Spanbroek salient. This, too, has cables
running to it, but, according to the latest prisoners’ statements,
little use is now made of telephones, as the cables are being
constantly cut by our artillery.
The headquarters of the company holding the Spanbroek
salient are at N.30.c.50.83. There is a large dugout at
O.25.b.05.37 and a group of dugouts at 0250.12.65, to both of
which points cables lead; another cable leads to O.25.b.05.75,
where there is probably an observation post. '
The cable system in this sector is diflicult to trace. There is
an exchange at O.27.c.20.50. On the map three cables are
NINTH CORPS‘ INSTRUCTIONS FOR THE OFFENSIVE. 45
marked leading to Pick house (O.26.a) ; of these only one is now
-visible, that leading- through Lumm farm _(O.26.c.10.75), it
therefore appears that Pick House is now no longer an exchange.
0n the other hand, Guy farm (0.26.a.30.80) appears to be the
junction of‘at least two lines, but the latest prisoners’ state-
ments make Guy farm a supply center for the electric lighting
in the dugouts in the reserve Stellung, and it is probable that
the cables visible on aeroplane photographs in its neighborhood
are power cables, which may also be the case with a number of
the cables in this locality, which have hitherto been considered
telephone lines.
TRAMWAYS AND DUMPS.
3. The main forward supply center for the sector is theldump
at the crossroads at 0200.20.35 at the end of the meter-gauge
railway from Comines.
From here lines run—
(a) Along the Wytschaete-Messines Road to Pick house,
where there is a dump of some importance; thence down the
valley south of the Enfer spur, along the northern edge of Enfer
wood and then-up the valley to the Kruistraat crossroads.
A short branch used to lead from the northern edge of the
wood to Earl farm where there was a small dump; but owing
to our shelling this dump has been abandoned andreplaced by
a dump in Enfer wood at O.25.d.30.20, which normally contains
a fair amount of materiel.
Further forward than this point it appears that the line is
little used. It is certainly not normally used along the Wyt-
schaete;Kruistraat Road beyond N .38.b.25.85. ,
No dumps are now visible in the forward area. There was a
temporary dump at O.30.d.03.12, but it is now empty—the mate-
riel having probably been used for the new trench in process of
construction behind Narrow reserve. _
(1)) Through the cutting along the old meter-gauge railway,
then turning down the Wytschaete-Kruistraat Road to the
Kruistraat crossroads, where it meets the first line.
A small section of line still appears to exist along the
_Wytschaete-Wulverghem Road from these crossroads to
N.36.b.0.6, the remainder of which originally continued to
Nathan support. It is possible that this section of the line is
used in connection ‘with mining operations.
The more important section of the line is that Which goes to
Hop Point (N.30.d).
46 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
South of Hop Point a line branches off to the west, crossing
Narrow reserve at N.30.d.05.85 and continuing to N.30.c.37.98.
This line was not much used in connection with the concrete in
the summer of 1916. It is now no longer in use.
North of Hop Point a line runs toward Peckham, crossing
Naples reserve at N.30.b.43.50. This line, too, has been little
used of late, and has become derelict in parts. The latest pho-
tographs show signs of shunting on the forward portion of this
line, and it is possible that the line as a whole will shortly be
reclaimed.
The northern and southern lines are linked up by a line run-
ning behind Naples reserve. This line, too, has fallen into
disuse.
COMMUNICATION TRENCHES AND TRAFFIC ROUTES.
4. The main communication trenches in the sector are——
(a) Occult Avenue, leading toward Kruistraat. Fire on the
section of this trench immediately south of Earl farm would
seriously dislocate any reenforcements, as the approach to the
front by any other way or across country is blocked by the wire
in the Steenebeek Valley. This communication trench appears
to be used only by the troops holding Nathan trench and reserve
and a portion of Occult trench.
(0) Ocean Alley, following the Yytschaete-Wulverghem Road
to Hop Point. From this trench Nap Avenue branches off to
Maedelstede farm and Naples Drive to Spanbroekmolen and
Peckham. The most vulnerable portion of this line of approach
appears to be the Sunken Road from about 0.19.c.75.10 to
0.25.a.60.90, which is open to enfilade fire, and through which
all trafiic must pass.
Another which is used is down the Wytschaete-Kemmel Road
to 0.19.d.16.60, then down Nap reserve, via. Nap Avenue, into
Nap Alley, and so to the front line. Troops also go via Nap
reserve and Naples reserve and Naples Drive and thence to the
front line by Narrow Lane.
When being relieved troops which hold the southern trenches
of this sector go back through Occult Avenue and October
Avenue, thence by road through 0.34, 0.35, and 0.36 to French
Comines, though different tracks and byroads are sometimes
used. _
The main route for troops from the northern part of the sector
is into Wytschaete and thence by the straight track through
0.20.c.d, 0.27.b, and O.28.a.b to French Comines.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 47
RESERVE LINE.
5. In view of the bad condition of the forward defenses, the
enemy’s main line of resistance is the line Nathan reserve-Nar-
row reserve—Naples reserve. This line was commenced in the
spring of 1916 and completed during the summer. It is well
built, with many good dugouts, and was very strongly wired. It
is situated on the reverse slope of the ridge, so that observation
is difficult.
A new Narrow reserve is being constructed, as previously
stated.
Naples reserve is still in good condition; although frequently
damaged by our bombardments, it has always been promptly
repaired.
A Minenwerferzug (trench mortar detachment) has its em~
placements and dugouts about‘ N.30.b.10.15.
The portion of Naples Drive east of this line is wired on the
south and forms a portion of a switch line centering on Hop
Point, called by the Germans Kaiserschantze (N.30.d). From
this point the switch continues southeast along Occult trench
to the Steenebeek Valley. Whereas Naples Drive is at present
only used as a communication trench, Hop Point and Occult
trench are both garrisoned; the eastern face of Hop Point,
especially, containing many dugouts.
The Steenebeek is strongly wired. The brook itself is no
obstacle, but the ground on either side is marshy in wet weather
and the valley is dominated by the Enfer Wood, which probably
contains machine guns.
The Reservestellung continues uninterruptedly from the Mes-
sines defenses along the top of the ridge and joins the
Wytschaete defenses at Ocean Lane (O.25.b). It contains a
number of strong dugouts.
The Wytschaete defenses are dealt with separately, and a
map is attached, G-5.
E. PETIT BOIS SECTOR.
N.24.c.90.55 to N.18.b.70.90 (sector at present held by Thirty-third
Fusillier Regiment, second division).
FRONT-LIN E DEFEN SES.
1. For some months no evidence has been available from
prisoners as to the condition of the trenches in this sector. On
48 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
the night of May 9—10, however, a prisoner was captured in
Petit Bois and information obtained from this man, together
with the reports sent in by patrols during April and the begin-
ning of May have made it possible to get a good general im-
pression of the trenches held in the sector and their condition.
As in the Spanbroek sector, the trenches in this sector have
suffered to a great extent from our bombardments.
Only the northern part, however, of the front line has ‘been
so badly damaged that the enemy has been compelled to abandon
it. Nags Nose (N.18.b) is now no longer held or even patrolled.
The enemy has constructed a new trench about 50 yards behind
this trench. To the south of this, in N.18.d, Nail trench is prob-
ably lightly held, and behind it the enemy has constructed
during the last six weeks Nail switch.
The front line in the Petit Bois salient is in a very bad state.
It is, however, occupied by isolated sentry posts, at intervals
of 30 to 40 yards during the night. During the day it is still
more lightly held. The absence of communication trenches from
this front line is remarkable, and it was suspected that the
front line was connected with the support line by underground
galleries. On one occasion, some months ago, it was noticed
that the front line was reinforced without any troops being
observed to move up from the support line. The recently cap—
tured prisoner, however, denies the existence of these suspected
galleries.
It is‘ probable that the enemy would not attempt to hold his
front line in this sector if attacked; and it appears that the
line Nancy support and Nail switch would be his first line of
resistance.
HEADQUARTERS AND TELEPHONE EXCHANGES.
2. No recent information is available about headquarters,
and the tracing of cables is very difficult owing to the ruins of
Wytschaete and the cover afforded by Wytschaete Wood. There
is a headquarters in the‘ wood at O.19.a.4.6. This was stated
by a prisoner taken in September, 1916, to be a battalion head-
quarters. There is another headquarters in the sunken road
about O.13.c.3.9.
Latest aeroplane photographs show what is almost certainly
a regimental headquarters at O.23.a.18.55. All around the farm,
which is situated at this point, there are signs of a large amount.
of movement and also traces of cables.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 49
TRAM‘VAYS AND DUMPS.
3. The main forward supply center for this sector is the im-
portant Wytschaete Dump at 0.20.a.3.1, which is fed by the
meter-gauge railway from Comines. '
At the present time the main line is that which was formerly a
branch line from the one along the Wytschaete-Kemmel Road.
This line branches off the road at O.19.d.1.9 and runs through the
Wytschaete Wood. Until the middle of April it terminated at
the dump at N.24.b.93.50; it has, however, now been continued
to N.24..b.90.55, where work of some importance is in progress.
As on the rest of the Ninth Corps front, there is a consider-
able diminution in the use of forward tramways as the. result
of the persistent shelling by our artillery.
COIVIMUNICATION TRENCI-IES AND TRAFFIC ROUTES.
4. This sector is well supplied with communication trenches.
In the south is Nap Drive, of which Occasion Alley is a con-
tinuation, leading back from Nap support.
Next comes Nancy Avenue and above this Nancy Drive, all
of which are in a very fair state of repair, though muddy in wet
weather. Nancy Street, which leads from the front line to
Nancy support, is in a very bad state and almost impassable in
places.
To the north, where they are more exposed, the communica-
tion trenches have suffered very severely from our artillery.
Nail Lane has now been altogether abandoned and Nail Drive
is in a poor state of repair. In April the enemy constructed
Nail Drive, starting along a zigzag hedge in N.18.d and leading
through Unnamed Wood. Nag Avenue (Sunken Road) serves
as a communication trench. It also contains dugouts, which are
occupied by supports.
As each of the existing communication trenches forms an
independent line of approach, it is diificult to select any par-
ticular points, the shelling of which would seriously disorganize
a relief. A bombardment of the crossroads at the Steenyser
Cabaret (0.20.c.2.8) and of Wytschaete itself would, however,
greatly interfere with a relief.
There are two main routes for reliefs in this sector. The
first is from Belgian Comines along railway to Cinema Dump;
thence by same route as for the battalion in the north of the
10049°-—17—-—4
50 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
Spanbroek sector, viz, by road to west of Garde Dieu Cabaret
(N.36.a.8.4); thence by tracks through 0.29, 0.28, 0.27.b, and
0.20.d and c to the Steenyser Cabaret. The other main route
is along the eastern bank of the Ypres-Comines Canal, across
the canal at Houthem; thence by road to junction'with main
straight track at 0.29.a.05.05.
REAR LINES OF DEFENSE.
5. Nancy support and Nail switch form a line of resistance
which is well wired. Nancy support has for a long time been
strong and the enemy has been putting a large amount of work
into it during the last six weeks; it is now very strong and
contains a large number of dugouts and probably machine-gun
emplacements. Until quite recently there was no continuation
of this line in a northerly direction, but the enemy has now
constructed a new line. behind Nail switch which runs through
the northwest corner of Grand Bois. Up to the present this
line is not very strong. '
The. supporting battalion in this sector is stationed in the
Wytschaete defenses, especially on the northern outskirts of the
village. These defenses are dealt with separately.
F. BOIS QUARANTE SECTOR.
N.18.b.7.9 to O.2.c.5.1 (sector at present held by Forty-fourth Infantry
Regiment, Second Division).
FRONT LINE DEFENSES.
1. The greater portion of the front line in this sector is in bad
condition. Oblige trench is held, Object support held only by
posts, Obit trench held, Obey trench not occupied. North of the
Boise Quarante, on either side of the Diependaalbeek, the ground
is inclined to be wet and marshy. There is a gap of about 400
yards in Obey trench, the trench itself having almost disappeared.
The first line of resistance in this sector would probably be
Object switch, Obit support, and Obey support.
HEADQUARTERS AND TELEPHONE EXCHANGES. .
2. As on the rest of the corps front, the tracing of cables is
very difficult. Cables are, however, visible at one or two points.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 51
There is a cable leading into Onraet Wood, and it probably
continues to Onraet farm, where there is a battalion headquar-
ters. There is also a suspected headquarters at O.7.d.3.0.
Cables can also be seen leading to Louwage farm (0.7.d),
Catteau farm (O.8.c), and Renty'farm (O.13.b). No recent in-
formation is available about headquarters.
TRAMXVAYS AND DUMPS.
3. All supplies for the sector are apparently brought up on
the meter-gauge railway from Comines to a large dump in
Oosttaverne Wood, which is supplemented by several smaller
dumps. The main dump is situated at the end of a branch line,
the last portion of which is doubled in order to permit of two
trains passing one another.
From this dump a tramway leads to a dump in Onraet Wood
at O.14.c.45.70, and continues forward through Grand Bois up
to the edge of the Bois Quarante. In the northern corner of
Grand Bois, about O.7.d.0.3, there is a group of dugouts close to
the tramline the continuation of which runs along the southeast
edge of the Bois Quarante, terminating approximately at
O.7.b.70.15.
At O.13.b.65.50 a line branches off through the wood. This
line used to run to N.18.b.8.9,' terminating near a large group of
dugouts, Now, however, it shows no signs of being used beyond
dugouts at O.13.a.7.3.
At the end of March the enemy built a new branch line from
O.7.d.3.2, which runs in the direction of Croonaert Chapel, ter-
minating where it reaches Object Alley at O.7.c.7.3.
In Grand Bois on either side of the ditch which drains into
the Diependaalbeek the ground seems to be very marshy, as
both portions of the line which cross this ditch run over light
bridges.
Prior to the construction of the meter-gauge railway in the
summer of 1916 a trench tramway system existed which con-
nected the dump at Houthem with diiferent' points nearer the
front, including Oosttaverne Wood and Wytschaete. This sys-
tem is now no longer in use as a whole. The line from the
Oosttaverne-St. Eloi Road at 015065.75 running southwest
through the wood seems, however, to be in use. It may be
used by the occupants of the group of dugouts in the wood around .
0.15.c.1.6, and may occasionally be used to help to swell the
large dump at O.20.a.35.10 up to which it runs.
52 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
COMMUNICATION TRENCHES AND TRAFFIC ROUTES.
4. The main communication trenches for this sector are Ob-
struction Alley through Grand Bois, Object Alley to Croonaert
Chapel, and communication trench from neighborhood of Zero
Wood (O.14.a) running up to the junction of Object switch and
Obit support at 0.7 .d.2.7. North of this there are no communi-
cation trenches west of the Wytschaete-St. Eloi Road, and the
enemy presumably uses the road and Oaten Drive, which runs
along the east side of the road and then turns into Obey Lane
to get to the front line.
The rest billets of the infantry are at Belgian Comines; those
of the pioneers at Houthem. The main route taken to the
trenches from rest billets is through Houthem, thence by roads
due west through 0.24, 23, 22, 21, and 20 to Wytschaete. Troops
sometimes go northwest from Houthem and use the military road
through O.18.d and c, rejoining the first route at crossroads at
O.23.b.10.55. Turning north just east of Wytschaete troops use
the Sunken Road, Obstruction Drive, and the communication
trench past Onraet farm to get into the communication trenches
already mentioned. There is no evidence available about the
routes used from recent prisoners’ statements, but the above
routes are confirmed by the latest aeroplane photographs.
REAR LINES OF DEFENSE.
5. The rear lines of defense are designed to defend the ap-
proach to the Wytschaete Ridge from the north and the north-
west. We find, therefore, that the intermediate line, after fol-
lowing the edge of the Grand Bois, swings round at Louwaege
farm and follows the general direction west and east on either
side of the Wytschaete-St. Eloi Road.
Louwaege farm, forming an angle in the defensive line, is an
important point and is therefore permanently garrisoned, as is
indicated by a considerable number of dugouts in the neighbor--
hood of the farm.
Two new additions were made to this line in March. The
first is the trench cutting off the angle made by Oblige Avenue
and Obstruction trench in front of Grand Bois in O.13.a; this ‘is
‘now known as Oblige switch. The other new trench runs north
from Louwaege farm toward the front line along the edge of the
Bois Quarante. This trench, now called Obstruction switch,
which has been constructed as a fire trench facing west and is
strongly wired, seemed likely to be continued north of the
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 53
Diependaalbeek in a northeasterly direction toward the St.
Eloi Road, forming an additional cover to Obey support for the
gap in the front line. In March the state of the ground no doubt
prevented work on a continuation of this trench, but even now
(May) there are no signs of the trench having been continued
in a northeasterly direction along the ditch. Two bays have,
however, been added in a north-north-northwesterly direction
from the head of this trench at 0.7.b.78.97.
From the Wytschaete-Vierstraat Road a line runs along the
rear edge of Grand Bois and joins onto the intermediate line
near Zero House (0.14.a). The portion of the line on the edge
of the wood is of considerable strength, being protected to a cer-
tain extent by the wood itself, by a strong belt of wire, and by
a strip of marshy ground in front of it. There are a number of
dugouts in the line about O.13.b.6.5 near Renty farm.
From the Wytschaete defenses near North House (O.19.b.9.9)
the Reserve Stellung runs in a northeasterly direction. The
enemy worked hard during the months of February and March
improving and strengthening this line which now consists of a
complete front and support line; even here, however, he has
failed to put in much work since the beginning of April.
From this line a belt of wire runs out inclosing Onraet \Vood.
North of the wood and on either side of the St. Eloi Road a
group of trenches, consisting of 0btuse Keep and 0btuse Cres-
cent, has been constructed evidently for the purpose of defend-
ing the approach along the road.
No prisoners have been captured in this sector for several
months, and therefore detailed and up-to-date information is
lacking.
G. WYTSCHAETE DEFENSES.
Reference map G5.
The village is situated on the highest point of the ridge. From
the west along the KemmelsWytschaete Road the approach is
gradual along the high ground; from the north the ground rises
gradually from the valley of the Wytschaetebeek.
The village has been made a strong point for all-round defense.
An inner line of trenches incloses the village itself. These
trenches, which have always been kept in a fairly good state of
repair, were worked on to a considerable extent during the
months of March and April, and work still continues in this
neighborhood. Some new trenches have also been dug. Apart
54 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
from work on the trenches the enemy has of late been putting
out new wire at various points, and still continues to do so,
especially on the western side of the village. A number of
machine-gun emplacements (the suspected locations of which are
shown on the map) and the existing vaulted cellars play an
important role in the inner defenses of the village.
The outer defenses are strongest on the north and southwest
sides of the village. Here are outlying strong points at the’
Enter spur, immediately west of Goderis farm (Skip Point),
and the Bogaert spur.
To the west of the village there are no special strong points,
but it is protected on this side by the Bois de Wytschaete, which
probably conceals strong obstacles in the form of barbed-wire
entanglements.
To the north and northwest the outlying defenses consist
entirely of trenches and wire with no outstanding strong points.
Generally its naturally strong position, the vaulted cellars,
the machine-gun emplacements, and the trenches and wire,
which have never been neglected and are still being worked on
at the present time, make Wytschaete a village capable of offer-
ing strong resistance. .
H. ENEMY’S REAR LINES OF DEFENSE.
EAST OF THE 'WYTSCI-IAETE-MESSINES RIDGE.
Behind the reserve line running along the top of the ridge west
of the lvlessines-Wytschaete Road and along the northwestern
edges of the Oosttaverne Wood and Ravine Wood, in which the
Messines and Wytschaete defenses form strong points, there
were practically no trenches until January, 1917. There were,
however, two strong and wide belts of wire; the first of these
starting from 0.34 central, about 2,200 yards east of the reserve
line, ran due north, passing in O.22.a east of Oosttaverne to
Ravine Wood (0.10). ~
The second was about 2,000 yards farther east. Coming up
from Warneton this line of wire ran just west of Garde Dieu
Cabaret (O.36.b), thence due north until, west of Pillegrem’s
farm (0.24.a), it. turned northeast and crossed the Ypres-
Comines Canal in P.13.a.
In January, 1917, the enemy began work on trenches behind
these belts of wire. He worked hard during the months of
January and February, and by the end of February had almost
completed a double line of trenches behind each belt of wire.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 55 -
The forward line through 0.22 and 0.16 is known as the Oost-
taverne line, and the line through 0.24 and 0.18 as the Kortewilde
line.
In the Oosttaverne line there is now a continuous trench which
follows the wire up to the southern edge of Ravine Wood, where
it branches off in a northeasterly direction, joining oblique trench
in 0.5.d. About 200 yards behind this trench is another trench
line.
The Kortewilde line now consists of a complete double line of
trenches up to the Ypres-Comines Canal. The support trench,
as is the case with the Oosttaverne line, is about 200 yards be-
hind the front line. At places work has been commenced on a
reserve line to this system.
As far as can be seen at present the enemy places compara-
tively little confidence in the Oosttaverne line, although from
sections taken it appears to be hidden for the most part from
the Wytschaete-Messines Ridge. There are practically no signs
of dugouts or emplacements in it. In February it seemed likely
that the enemy was going to make the Kortewilde line very
strong. Dugouts and signs of emplacements could be seen at
various points, especially in 0.24 and 0.30. During the months
of March and April be, however, neglected both these lines, leav-
ing the trenches shallow and doing no further work on dugouts
or emplacements.
This attitude has continued during the present month (May).
The Oosttaverne line has fallen into complete neglect; while the.
enemy seems to remain undecided about the Kortewild'e line, as
there are several points at which he has aln'mdoned the original
line and started to work on new portions of trenches.
I. STREAMS.
GENERAL.
The ridge running northeast and southwest forms the water-
-shed for the Stl't-‘RIIIS opposite the corps front.
The streams which drain this ridge in a northwesterly direc-
tion are the Diependaalbeek and the Wytschaetebeek.
Draining it in a southeasterly direction are the Bassevillebeek,
Palingbeek, Roosebeek, Wambeek, Blauwepoortbeek, and the
Steenebeek. With the exception of the Steenebeek, all these
last-named streams go to swell the Kortekeerbeek, which even-
tually flows into the River Deule.
56 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. '
STREAMS FLOWVING IN A NORTH\VESTERLY DIRECTION.
DtependaaZbeeh.—Rising in the wood in O.9.c, this stream flows
northwest through a valley with regular slopes until it flows
under the Oosttaverne-St. Eloi Road in O.8.b. Up to this point
it is merely a ditch. Here it turns west—southwest to O.8.c.3.8,
where it resumes its original course. It crosses “No Man’s
Land” just north of the Bois Quarante. In itself this stream
presents no military obstacle; the meadows in O.8.c, and more
particularly in 0.7 .b, have, however, a marshy tendency and are
liable to become flooded in rainy weather.
The Diependaalbeek has two main aflluents. The first, which
rises at O.13.c.8.8, is at its outset a mere ditch, but the valley
through which it flows is liable to be swampy and is overgrown
with vbushes. Except about O.13.b.7.6, where its western bank
rises to a height of about 12 feet, this affluent presents no mili-
tary obstacle.
The other main affluent is formed at O.8.c.2.1 by the junction
of two ditches, which start a little further south. It is quite
negligible and the valley through which it flows is generally
absolutely dry. It flows into the Diependaalbeek at O.8.c.9.7,
which the other aflluent comes in about 300 yards further east.
Wytsehaetebeeh.——Rising at the southwest corner of the Bois
de Wytschaete this stream flows in a northerly direction through
“No Man’s Land,” entering our lines by the sunken road in
N.18.a. During the heavy rains the meadows north of the Wyte
schaete wood are flooded by this stream. The banks are steep in
places and covered with undergrowth. The stream is in parts 4
feet wide, and it has about 3 feet of water on a bed of soft mud.
Except after heavy rains it would present no obstacle to the
passage of troops.
STREA M S FLO\VING IN A SOU'I‘I-IEA STERLY DIRECTION.
Steeneheela—Jllhis stream rises in N.30.b in the pond near
Peckham farm. Flowing southeast to the western edge of
Enfer wood it there turns south and, entering “ No Man’s Land ”
in U.1.b, eventually flows into the Douve River. The Steenebeek
in itself presents no obstacle to the passage of troops. The
ground through which it flows is, however, marshy and its val-
ley has been made into no mean obstacle by the enemy, who have
wired it heavily and command it with machine guns from several
points. The stream itself is nowhere more than 4 feet wide.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 57
with an average depth of about 2 feet. It becomes dry in the
summer, but easily overflows in really wet weather and floods
the meadows on either side.
There are two small aflluents to the Steenebeek. The first
starting from O.25.a.15.90 flows into it at O.25.a.03.18. The sec-
ond, rising at 0.25.b.53.60, flows down the gulley west of the
Enfer spur and joins the Steenebeek at O.25.d.06.40.
Bassevillebeek.—This stream presents no obstacle to the pas-
sage of troops. Supplemented by the Palingbeek, which comes
from P.1.c, and the Gaverbeek, which comes from P.4d, it goes
to form the Kortekeerbeek at P.13.b.68.97. Its banks are steep
and its bottom marshy, but the smallness of its dimensions
renders this stream almost negligible.
Palingbecla— ( See Bassevillebeek. )
RoosebeeIc.-—This stream is formed at 0.15.03.4- by the junc-
tion of several ditches in Oosttaverne wood. During dry
weather it is negligible in 0.15, where it would not interfere
with the passage of troops, being only about 3 feet wide and
often comparatively dry. Through 0.16 it gradually increases
its dimensions, the width and the depth of the bed both reach-
ing 4 feet to 5 feet. In 0.17 .b it begins to present a slight mili-
tary obstacle. The banks are about 9 feet apart, the depth of
the bed is about 6 feet, and the average depth of water about
2 feet, though when in flood it flows level with its banks.
The Roosebeek is, however, passable throughout except when
in flood. It is bordered with pollards and bushes for the most
part, and the valley through which it flows gives cover from
all sides except just southwest of Hollebeek, where it is exposed
to the east.
Wambeela—Formed in O.20.b, this stream flows eastward. At
0.22.d.3.2 it passes under the road through a brick culvert,
which is about 9 feet wide and 6 feet high. After passing
through another culvert at 0230.30.15 it flows through low-
lying meadows. At 0.30.c.48.80 it is supplemented by the
Blauwepoortbeek and attains a width of 6 feet. It flows in
its normal course to P.25.c.60.90. where the bed has been
straightened for about 150 yards, and becomes 7 feet wide and
7 feet deep. Finally, at P.25.d.45.92, it flows into the Korte-
keerbeek. Except for the short piece where the bed has been
straightened, the Wambeek presents no military obstacle. It
is never more than 3 feet deep and its bed is at no point more
than 5 feet wide; in summer the water is less deep, and some-
times this stream dries up entirely. There are no hedges on
58 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
the banks, while the stream is bordered almost throughout with
small willow trees.
Blauwepoortbeen—This stream, starting in O.27.c, north of
Messines, flows in an easterly direction until in O.30;d, where it
flows into the Wambeek.
At its outset this stream is quite insignificant. At O.34.c.8.6
it flows through a pond. From here until in O.34.b, where it
passes Delporte farm, the stream is only about 4 feet wide.
East of this point it widens out a little, but is nowhere more
than 6 feet wide between the banks and 4 feet at the water
level. The course of the Blauwepoortbeek lies through a valley
of gently-sloping, low-lying meadows, which are as a rule
quite dry. It has very little water in it, is not subject to floods,
and presents absolutely no obstacle to the passage of troops.
Ifortekeerbeek.—As' already stated, this stream is formed at
P.13.b.68.97. In P.25.d it is further supplemented by the Wam-
beek. South of this point it presents a considerable obstacle to
the passage of troops, being in places over 15 feet wide and not
passable except by bridges. It eventually flows into the River
Deule.
J. WOODS.
GENERAL.
The woods opposite the corps front may be roughly divided
into two classes—woods west and east of the St. Eloi-Wyt-
schaete-Messines Road. On the woods west of this road the
Bois Quarante and the Petit Bois are practically in the enemy’s
front line and are almost negligible. The other woods are the
Grand Bois, Onraet Wood, unnamed wood, Wytschaete Wood,
~L’Enfer Wood, and the smaller woods Skip and Pick Woods.
East of this road the only wood of importance is the Oost-
taverne Wood, the other woods being Zero Wood, Bug Wood,
Green Wood, Van Hove Wood, and Leg Copse.
vWOODS EAST OF THE ST. ELOI-MESSINES ROAD.
Bots Quawmte—This wood lying behind Object Trench and
Obit Trench has been much thinned by shellfire and presents
little obstacle to the passage of troops.
Petit Bots—This wood which lies in N.24.b was formerly
composed of tall oak trees; it has been badly damaged, and now
consists of scattered tree trunks with little or no undergrowth,
and presents only a slight obstacle.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 59
Grand Bots—Situated in 0.13, this wood is. generally com-
posed of large oak trees, saplings, and a fairly thick under-
growth except in the westernmost corner.
In the northeast are young trees planted about 5 feet apart
in regular rows. '
In the west is a small low-lying meadow, inclined to be wet,
where an afiluent of the Diependaalbeek rises. This part of the
wood is, however, practicable.
Along the southeastern edge the undergrowth is thick, and
marshy ground extends on either side of the brook flowing
through this part of the wood. .
In 0.13.b there is a bank along the stream which, rising to a
height of 10 to 15 feet, is steep and planted with bushes and
trees.
This bank is, however, the only natural obstacle in the wood,
and apart from _it the wood is nowhere inclosed and has no
ditches of any size in it.
Onraet Wood (0.14.c).—This wood still remains compara-
tively thick. Composed of large oak trees, it has a fairly thick
undergrowth. The eastern edge of the wood is 5 feet below the
level of the road. The slope of the wood is, however, regular
and the ground is unbroken. Before the war this wood would
have presented no obstacle to the passage of troops. It never-
theless affords cover for dugouts and entanglements and may
well have been converted into a considerable obstacle by the
enemy.
Unnamed wood '(0.13.c).——The trees in this wood are smaller
than in _the majority of the woods in the neighborhood. but
planted rather close together. This wood, too, has, however,
been very badly damaged by shellfire and should present no
natural obstacle to the passage of troops, while it is no longer
sufliciently thick to afford any real cover for the enemy.
Skip and Pick I'VOOd-Sr—TIIBSC are two small woods in 0.25.0,
along the southwestern edges of which flows the Steenebeek.
They have been badly damaged by shellfire and present in them-
selves no cover or obstacle to the passage of troops.
l-l’ytsohdeie Wood (N.2-'l.b, 0.19.a).———This wood, called by the
Belgians Godschalk Wood. presents an obstacle to the passage
of troops and also affords considerable cover for the enemy.
In the north of it is the Godschalk estate, which, comprising
about 50 acres, consists of numerous banks and other obstacles.
With the exception of two small portions in which there are
30-year old larches the wood is composed of very large oak trees
60 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
reputed to have been the finest in the whole countryside. The
undergrowth is composed of trees which are normally cut
down every seven years. ‘
Small canals have been constructed in the wood. They are
situated at the bottom of ravines 6 feet to 10 feet in depth.
The width between the banks of these canals is from 8 feet to
12 feet and the depth of the water varies between 18 inches
and 3 feet 3 inches. The bottoms are always very slimy. The
pond, situated at O.19.a.4.6, is in a hollow and it receives water -
from the Wytschaete Plateau. The depth of the water rarely
exceeds 4 feet, but the bottom of the pond is composed of slime
which is from 6 feet to 10 feet deep.
The ground is marshy in several places, some parts of the
wood being impassable. These marshes are mainly to the
northwest of the pond, and around another pond at the south-
west corner of the wood, also about the water at O.19.a.5.2. The
portion of the wood on the bank of the Wytschaetebeek is on low-
lying ground, and the soil here is saturated with water except
in very dry weather.
Enfer Wood (O.25.d).——The wood is still thick. Though in
itself no real obstacle to the passage of troops its situation never-
theless makes it a wood of considerable importance. It lies on
the northwestern slope of a hill and to the northeast of it is
the Enfer Spur. The eastern edge of the wood is on the saddle
between these two hills, while its western edge is bounded by
the Steenebeek. The wood affords considerable cover for the
enemy and no doubt conceals several machine-gun emplacements
commanding the Valley of the Steenebeek.
IVOODS EAST OF THE ST. ELOI-NIESSINES ROAD.
Oostta/nerne wood—This wood is composed principally of
fir trees and oaks. These are not planted very close together
and the passage of the wood is easy in all directions. The por—
tions at O.15..c.10.10 and 40.20 were cut down a few years before
the war and replanted; the young trees here are about 3 feet
to 4 feet high.
Except for one small stretch from 'O.15.c.4.5—6.5 the whole
of the wood is enclosed by an earth (like. This dike which is
bordered on either side by a deep ditch is more than 4 feet
above ground level and measures about 8 feet across the top.
The passing of this (like would be difficult, especially as the
inner ditch is very wide and in places serves as the bed of a
stream.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 61
At about 0.15.c.1.6 and 3.4 the ground is low-lying and in-
clined to be marshy, and there is another wet part about
O.14.d.6.l in the proximity of a circular pond.
Except for the above-mentioned places the ground in the wood
is as a whole uniform, with no banks or broken ground, while
the soil is dry and practicable.
Leg copse—This copse is really a strip of trees about 300 yards
south of Oosttaverne wood. Regarded as a military obstacle,
this copse is quite negligible.
Zero and Bug woods—The first of these two small woods lies
just east of the road north of Onraet wood. The second lies in
0.16.0. They are both insignificant and negligible from a mili-
tary standpoint. .
Green wood (0.17 .a) .—-This wood comprises large oaks, shrubs,
and bushes; in the north and northeast portions there are also
tall poplars and a rather thick undergrowth. The wood is
intersected by a number of small ditches; these are of no im-
portance and the wood generally presents no real military
obstacle.
Wood in O,22.b.—-—This is a small wood lying southeast of Van-
h'ove farm. The ground level of the wood is about 2 feet higher
than the level of the road and forms a bank. This wood, which
lies on a gentle slope toward the south, is not likely to present
any obstacle in itself.
K. YPRES-COMINES CANAL.
From Comines to west of l\'m'tewilde, which is the portion con-
cerning the Ninth Corps, the average dimensions of the canal
are as follows:
Depth of bed, 10 feet.
Width at bottom of bed, 32}- feet.
Estimated width at water level, 52 feet.
Width from bank to bank, 58% feet.
Width of towpaths, 13 feet, of which 8 feet are practicable.
All banks were constructed with slope of 34°.
These dimensions were taken after the latest work on the
canal, about 10 years ago, and they have been modified in places
owing to the shifting nature of the soil.
The locks are 146 feet long and 17 feet wide.
The canal appears to be generally dry except the portion be-
tween Comines and Houthem, which appears to be used on
occasions.
62 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
The following are the main bridges in this portion:
(a) Towpath bridge at V.4.b.30.10.—This is an iron arch foot-
bridge with a wooden footway. It has one span of about 70
feet and is about 3 feet wide. The height above water level is
about 13 feet.
North of this bridge the banks are of masonry for a distance
of about 150 feet. -
( b)_R0ad bridge at P.34.0.9.4.'—This is a permanent iron bridge,
supported on two masonry approaches. The roadway of the
bridge is paved and 16 feet wide, with a pavement of 3 feet on
either side. It is 24135; feet above the waterway of the canal.
A double lock is situated immediately north of this bridge.
(0) Railway bridge at P.3ll.c.4.9.—-This is an iron swing bridge
for a single track. The approaches are of masonry and hewn-
stone blocks. Its length is 53% feet. The bridge has proved
rather weak and all trains have to pass over it at a slow speed.
(d) Rodd bridge at P.2'7.d.1.1 (Pont du Korentje).-—’This is a
drawbridge with a wooden roadway for single traffic. It is
pulled up from the east bank of the canal. The approaches are
masonry and 20 feet wide.
('0) Road bridge at P.20.I).'7’./; (Pont du Gladje).—This is an-
other drawbridge. It is designed for light traffic only. The
approaches are of masonry and 20 feet wide. The roads leading
to the bridge are ordinary mud roads about 16 feet wide.
Immediately above this bridge there is another lock.
(f) Rodd bridge at P.20.a.4.0 (Pont de Houthem).——-This is
an iron drawbridge 21-12- feet in length. The approaches are of
masonry and 20 feet wide. It is a drawbridge with a roadway
for single traffic and two small pavements. The roads leading
to the bridge have a total width of 35 feet.
(9) Road bridge at P.13.d.65.05.—This is an iron drawbridge,
21% feet long, with a wooden roadway for single traffic. This
bridge, too, has masonry approaches, which are 20 feet in width.
The roads leading to the bridge have a total width of 35 feet.
(h) Wooden drawbridge at P.13.d.6.6.——This bridge is simi-
lar to the one at P.26.b.7.'4. It is 21% feet long and designed
for single traffic. It has masonry approaches 20 feet wide. The
roads leading to the bridge are ordinary mud roads and 16 feet
wide.
In addition to the above bridges, several bridges for trench
tramways and foot traflic have been constructed by the enemy.
APPENDIX V. '
SCALE OF AMMUNITION, GRENADES, ETC.
1. Table A shows the scale of artillery ammunition authorized.
Table B shows the scale of S. A. A., grenades, etc., in divisional
charge, and additional scale available for operations, with its dis-
tribution to army and corps reserve and to divisions.
2. Instructions as to distribution and expenditures of am-
munition in Table A are given in “ Ninth Corps Instructions for
the Offensive, Part II, Artillery.”
3. P. bombs, M. S. K. grenades, and smoke candles should be
drawn gradually up to the end of the month. The other stores
may be drawn at once.
4. The stores for reserve division will be retained in corps re-
serve until required by the division. .
5. All ammunition echelons will be kept up to establishment.
Ammunition issued from an echelon on an emergency will be
replaced at the first available opportunityQ
S. A. A. limbers of regimental and machine-gun company
transport will be ready loaded up by Zero hour and will not be
unloaded without orders from divisional headquarters.
G. S. wagons of ammunition columns may be unloaded if re-
quired for other purposes, but the loads will be stored in such a
manner that they can be readily reloaded if needed.
6. (a) Ammunition now dumped for the defense of the line
will be gradually redistributed for the offensive. Distribution
of this ammunition is left to divisions, with the proviso that
main dumps should be conveniently situated for roads or tram
lines, and that the number of advanced trench dumps be kept
as few as possible.
(b) Ammunition, etc., already dumped with divisions in ex-
cess of Table B will remain in divisional reserve dumps, but will
not be sent forward without sanction of corps.
7. Maps showing positions of all dumps should be prepared to
assist new troops in finding them and to facilitate salvage.
8. A distinguishing mark for dumps formed in the German line
1!
will be E511’ (lettering black on a white ground). This will be
notified I to all concerned.
63
64 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
9. Particular care must be taken to regulate the dumps at the
guns so that in the event of guns being advanced, as little ammu-
nition as possible will remain at the old gun positions.
At positions at which boxed ammunition has been stored, not
more than is likely to be required to meet, immediate require-
ments will be unboxed at a time. The cases containing the 4.5-
inch howitzer cartridges are not to be opened unless likely to be
required.
Ninth Corps H. A. and Divisions will arrange that the ammu-
nition left behind is either fetched by batteries from their new
positions or is collected in positions accessible by rail or road.
Divisions will arrange to keep a sufficient reserve of boxes to
rebox any ammunition that has been unboxed and left behind at
old gun positions.
10. In addition to reserves on limbers, machine guns employed
for barrage fire will be in possession of the following amounts
of ammunition at Zero hour:
3,500 rounds belted at the gun.
8,000 rounds at the belt-filling depot.
8,500 rounds in reserve dumps.
11. K. and K. N. ammunition will be reserved for machine
guns.
12. In view of the restricted amount of medium and heavy
trench mortar ammunition available for operations, it is impor-
tant that the best use should be made of available resources,
which should be distributed according to tasks required. Any
tendency to overdump near trench mortar positions at a dis-
tance from tram lines should be avoided, so as to keep trench
mortar ammunition available for redistribution when required.
13. The expenditure of 3-inch Stokes ammunition before Z
day should be limited as much as possible; 3-inch Stokes ammu-
nition not immediately required with‘ the guns should be col-
lected in divisonal and brigade dumps.
14. Divisions should apply for stores in corps reserve as re-
quired. '

APPENDIX VII.
SIGNAL COMMUNICATION.
1. The principles laid down in S. S. 148, “Forward Inter-
communication in Battle,” will be strictly adhered to with the
exception of alterations as regards signal calls laid down in
paragraph 8 of these instructions.
2. Heavy artillery groups supporting divisions and the coun-
ter—battery groups who are ordered to send forward observation
parties will arrange direct with divisions they are supporting, or
with divisions in whose area they wish to observe, as to how
communication can best be obtained and as to what parties, etc.,
they are to supply to assist divisions in giving them the re-
quired communication.
VISUAL COMMUNICATION.
3. This will be under divisional arrangement.
A central corps visual intercepting and receiving station will
be established at Kemmel in the corps O. P. No. K-20 map refer~
ence N.26.a.2.6.
This will be supplementary to the divisional system. Its call
will be N. Forward stations will be informed of its position.
Acknowledgment will be made by lamp if possible. The posi-
tion of this lamp will be notified later.
WIRELESS,- PowER BUZZERS, AND AMPLIFIERS.
4. The sets and personnel of corps wireless section and sub-
sections will be pooled and allotted to divisions by A. D. signals
as may be required. The following sets have been allotted:
Six wireless trench sets for use of heavy artillery supporting
divisions.
Four amplifiers and six power buzzers per division in the
line. _
A reserve of two trench wireless sets will be. available. Two
amplifiers and six power buzzers will, it is hoped, also be avail-
able, but these have not yet been obtained from army.

The corps wireless directing station will be situated at
Scherpenberg.
ACCUMULATORS.
Very careful arrangements will be required to insure proper
supply of accumulators for wireless, amplifier, and power buzzer
sets.
Sets will, in the first instance, be issued with a double supply
of accumulators; the spare set belonging to forward stations
will be left at back stations. Arrangements must be. made
locally to send these spare accumulators up to forward stations
as required.
Used and damaged accumulators must be returned to re-
charging stations, which will be situated as follows:
Left and center divisions at Scherpenberg.
Right division at Dranoutre.
PIGEONS.

the birds from second loft being on their way to the refilling
point, the third loft resting.
A motorcyclist dispatch rider is attached from Corps Signal
Company to each division to assist in superintending the supply
of birds to refilling points. Divisions will select and make all
arrangements as to supply of birds to refilling points and for-
ward. No birds have been allotted for the use of either tanks,
corps cavalry, or heavy artillery supporting divisions. Divi-
sions will make allotment as considered necessary.
'70 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
AEROPLANE LIAISON.
6. The instructions contained in 8.8.148 re “ Signaling to aero-
planes” will be carried out with the following modifications:
Thirty Watson fans, if available, will be allotted to battalions.
When flares are lighted to indicate to the aeroplane the posi-
tion of our troops those fans will be waved from side to side,
care being taken to wave the fan in such a manner that its white
side will be visible to the aeroplane.
TANKS.
7. Communication with tanks will be in accordance with
8.8. 148. '
Pigeons will be allotted as required by the “division with which
the tanks are cooperating.
RUNNERS.
8. It is essential that runner routes are'carefully marked
and that relay posts are organized and formed at. suitable dis-
tances and places vide 8.8. 148.
POSITION CALLS.
9. These will- be used up to Zero hour, and on the existing
telephone system, where they are at present used, after Zero
hour.
The signal calls to be used by troops taking part in the attack
will be the Ninth Corps code calls. These will be used as the
calls for telephone and visual stations and also as the address
“to” and “from” of units.
Brigade headquarters and higher formations should be in
possession of a copy of the code calls for all units in the Ninth
Corps; other units must be in possession of the necesary
extracts.
Companies will use the battalion code calls with the letters
-A, B, C, D added to indicate the company.
Power buzzer and amplifier stations will use the calls allotted
by second army to units for aeroplane liaison work, companies
will take battalion call with the letter A, B, C, D added. The
calls allotted by second army to units of the Ninth Corps for
aeroplane contact‘work are given in Appendix VIII.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 7I
BURIED CABLES.
10. These have been allotted to divisions and Ninth Corps
H. A. by A. D. Signals. Divisions will be responsible for the
allotment and maintenance of the buried-cable system in their
areas. _
Buried-cable routes will be extended as quickly as possible
after Zero hour under direction of A. D. signals.
It has been decided to first extend the left cable head of the
right division from about N.29.b.90.40 to 0190.95.35.
Twenty-eight pair-s of cables will be laid.
The following allotment of pairs is made: 6 pairs to each divi-
sion, 6 pairs to Ninth Corps H. A.. and 4 pairs reserved for
E Corps Signal Company. '
Sixteenth and Nineteenth Divisions, Ninth Corps H. A., will
make arrangements with A. D. Signals as to how these cables
are to be suballotted, and to what units they are to be con-
nected.
Revised maps of buried cable system will be issued shortly on
the scale of 1 per Infantry Brigade and Artillery Group.
CABLES OTHER THAN BURIED CABLE.
11. On no account are single, i. e., earth return circuits to
be laid anywhere in the Ninth Corps area. Only twisted cable
is to be used. All lines must be labeled to facilitate repair and
identification.
Care must be taken not to block roads or paths by carelessly
laid lines. Such lines interfere with traffic and are seldom of
any real value to their layers.
Lines laid in the present corps area must have at least 18 feet
clearance over main roads fit for motor transport, also over
broad-gauge railways. A clearance of 12 feet must be given
over other roads and tracks and light railways.
STORES.
12. A. D. Signals will issue a supply of twisted and armored
cable with which divisions will form forward dumps. Divisions
will send in estimates of their requirements of A. D. Signals as
soon as possible.
It must be impressed on all ranks that the supply of cable
is very limited, and every effort must be made to save unneces-~
sary waste. '
'72 ‘ NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
Units must not use their mobile equipment except in emer-
gency, and the fact that it has been used should be reported
at once.
TELEPHONE SYSTEM IN BACK AREA.
13. The system of fixed or locality exchanges has been estab-
lished in the corps area to relieve divisions and heavy artillery
of administrative work. Exchanges are situated as below:
St. Jans Capel.
Haegedoorne.
Dranoutre.
Locre.
Scherpenberg.
Westoutre.
Kemmel (N.26.b.2.6.).
A list of units connected to these exchanges will shortly be
issued. It should be impressed on all ranks that offensive oper-
ations necessitate a great strain on the telephone service, and
especially the exchange operators.
All calls should be as brief as possible, and no unnecessary
calls should be made. I ‘
At headquarters of formations, where offices are situated in
close proximity to each other, the telephone should not be used
for interoflice communication except in exceptional circum-
stances.
Attention is called to second army routine order No. 849,
which must be strictly adhered to:
Lack of system is occasioning considerable congestion in the
telephone service.
In order to minimize delay, the following rules, based. on the
methods in use at large telephone exchanges, will be strictly
observed:
1. Every officer or. man receiving or giving a telephone call
will first of all call out the unit or formation he belongs to;
e. g., “E. T. 001, orderly speaking,” or “ Thirty-eighth Division
G, G. S. O. 2 speaking,” or “Eightieth Division Q, D. A. and
Q. M. G. speaking.”
“Hello,” “Are you there,” “Hold on a minute while I fetch
an officer,” and similar introductory phrases are not‘ to be used.
2. The “position call” will be used within the danger zone.
3. The practice of orderlies or clerks giving calls, and sum-
moning the officer concerned only after a reply has been re-
ceived, will cease.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 73
TIME SIGNAL.
14. Time signal will be sent at 9 a. m. to divisions.
0n and after June 1 time signal will be repeated again at
noon. Divisions and heavy artillery will make the necessary
arrangements to insure that all watches are synchronized.
PRIORITY.
15. (a) 'l’elegrama—llelegrams marked “ Urgent operation
priority” will take precedence for transmission over all “ Pri-
ority” telegrams.
The only telegrams to be so marked are those in direct con-
nection with operations and of such urgency that a saving of
minutes in transmission is important.
A telegram addressed to several addresses must only be in-
dorsed “Urgent operation priority ” to the address or addresses
requiring special transmission.
Other than general oflicers commanding, only the following
oflicers will be authorized to frank “ Urgent operation priority ”
messages:
Corps: B. G. G. S.
H.
Division: G. R. A.
. S. O. 1.
A. A. and 0. M. G.
Brigade: Brigade major.
Staff captain.
Aeroplane and Zeppelin messages, if sent by telegraph, will
invariably be sent “Urgent operation priority.” .
It must be clearly understood that under no circumstances
will staff or other ofiicers, except those mentioned above, be
allowed to frank “Urgent operation priority” messages even
as representing the head of their branch. It is always open
to a staff officer as representing his commander to decide per-
sonally at the signal ofiice the order in which the messages
awaiting transmission are to be dispatched. (F. S. Regulations,
part 1, sec. 18, par. 2.)
74 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
The indorsement of messages as “Urgent operation priority ”
is to be sparingly used, or the object of introducing it'will be
defeated.
The use of “Priority” messages will be limited to those
oflicers now authorized by Appendix I of General Routine Or-
ders to frank “Priority ” and such messages and to the general
staff officer on duty.
(1)) Telephone calla—Telephone calls will be divided into two
classes, namely, (i) Ordinary, (ii) Priority. _
A “Priority ” call to an oflice already engaged will be put
through as soon as that oflice is disengaged and will be given
precedence over any other calls that may be waiting. Circuits
already in use will not be broken in favor of a “ Priority ” call.
For the smooth working of the telephone system it is essential
that “Priority ” telephone calls should be kept to a minimum
and that the duration of the call itself should be brief.
Signal offices will be furnished with a list in duplicate of the
oflicers to whom authority to use “Priority” telephone calls
has been granted by the G. O. C.
“Priority ” is to be reserved for calls of tactical importance
and urgency, and authority to use it is to be sparingly granted.
Oflicers making a “priority” telephone call must give their
name to the telephone-exchange operator as authority for the
“priority” call.
SPECIAL DISPATCH RIDERS.
16. Authority to send special-dispatch riders will be as for
“ priority ” telegrams.
CODES AND CIPHER.
17. The use of all codes other than the following is forbidden:
Field cipher.‘
Playfair cipher.
“B. A. B.” code book (unless superseded by second
Army code).
Army code.
Code calls.
Aeroplane Liaison Code.
CAPTURED SIGNALING EQUIPMENT.
18. All captured signaling equipment must be handed over
without delay to the divisional ordnance officer, who will issue
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 75
to the oificer i/o signals of the division any serviceable tele-
phones or telephone equipment which is required to replace
deficiencies. The remainder will be sent to the A. D. 0. S. of the
corps, who will hand over to the A. D. A. S. any articles the lat-
ter may require, either for issue to replace deficiencies or for
experimental purposes.
Any surplus to the above requirements should be returned
through the railhead ordnance officer to the base as early as
possible.
APPENDIX VIII.
CONTACT PATROLS.
1. Aeroplanes for contact patrols will be R. E. 8 type and
will be specially marked by a black flap attached to the rear
of each lower plane. Photographs are being issued.
2. Two contact aeroplanes will be in the air at the same time,
one watching the area south of Wytschaete and the other
Wytschaete and area north of the village.
Contact patrols will fly over the line and call for flares at the
following hours, and any hours subsequent to these hours at
which special aeroplanes may be ordered. Troops will also be
prepared to put out flares at any other time if the aeroplane calls
for them:
Zero plus 0.45.
Zero plus 2 hours.
Zero plus 4.20.
Zero plus 5.20.
Zero plus 6.30.
Zero plus 11 hours.
3. Aeroplanes will call for flares and Watson fans by sound-
ing a Klaxon horn and firing a Very white light, or by giving
either of these two signals.
4. Green flares will be used. They should be lighted in
bunches of three, each about 30 yards apart.
Watson fans will be used in conjunction with flares. The
fans should be turned over every two seconds, and not quicker;
that is, the white side will be exposed to the aeroplane for two
seconds and the dark side for two seconds, and so on. An issue
of 300 fans per division will be made as they become available.
5. The corps dropping ground will be in the field southeast of
the La Clytte-Locre Road in M.17.b and d, ‘just west of the S
in Scherpenberg, and will be in charge of Second Lieut. M. R.
Montgomery, Second Royal Dublin Fusiliers.
Sixteenth and Nineteenth Divisions will each detail six run-
ners and Ninth Corps Cavalry Regiment, six mounted orderlies
to report to Second Lieut. Montgomery at M.17.b.15.00 at 10
a. m. Y day.
6. In order to obtain as early intimation as possible from our
own aeroplanes of hostile counter attacks, the following pro-
cedure will be adopted:
76
NINTH ‘CORPS INSTRUCTIONS FOR THE OFFENSIVE. 77
On the hostile infantry being seen to quit their trenches and
advance, the observer will send down by wireless SOS followed
by the zone call—no map coordinates will be given. This will
constitute a request to our artillery to put up a barrage on
their SOS lines in that particular zone.
In order to avoid unjustified calls, R. F. C. observers will be
given to understand clearly that the SOS signal is only to be
used when hostile infantry have left their front trenches and are
advancing in the open in the direction of our own lines.
A machine for the purpose will be up from Zero.
7. R. F. C. observers will be warned not to attempt to fire at
or to drop bombs on the enemy, but will confine their reconnais-
ances entirely to observation and transmission of information.
8. No aeroplanes will be in the air before Zero. ‘
9. A schedule of code calls for aeroplanes to be used by divi-
sions is attached.
10. Tenth Corps contact aeroplanes will be distinguished by
three broad white bands on the fuzelage and also by a black
board on the lower left plane.
Second Anzac contact aeroplanes will be distinguished by two
black streagmers on the lower right-hand plane.
TANKS.
11. Tanks in action will be shown on contact aeroplane re-
port as E:
>
Derelict tanks will be shown as CI]

TRENCH TRAMWAYS.
1. The following trench trainways exist in the‘ corps area:
(a) RIGHT DIVISION.
Kingsway tram—From Daylight Corner, past Tea farm,
Cooker farm to 8.P.6/, where a branch turns south to Shanius
farm. ' I
Regent tram—From Lindenhoek through Spy farm to Regent
' Street dugouts, with a branch from Spy farm to Piccadilly,
known as “Piccadilly Line.” '
These trams are in connection by 60 cm. with broad-gauge
railhead at Lindenhoek, and also with the Ouderdom light rail-
way system by 60 cm., which runs from Lindenhoek along York
Road. >
(b) CENTER DIVISION.
Alberta line—From Kemmel village along the Wytschaete
Road to Parrain farm, where it leaves the road and goes to
Alberta dugouts.
Rossignol Zine—From Rossignol through Rossignol Wood,
past Alston House to Vandamme farm.
R. E. fawn Zine—From R. E. farm to York Road near Rossig-
nol.
Wailing farm—From York Road near Parret farm, past
Wiltshire House to Watling Street at N.17.d.5.8.
These trams are in connection with the Ouderdom light rail-
way system at Parret farm and in Kemmel village, and with
broad-gauge railhead at Lindenhoek by 60 cm. along York Road
to Lindenhoek.
(0) LEFT DIVISION.
Ridge Wood tram—From Hallebast Corner, past Bardenburg
through Ridge Wood to the Brasserie; from this point one
branch goes to Bois Confluent, and another to the reserve line
78
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 79
in Bois Carré, and a third runs along the road toward Vier-
straat to Poppy dump, where it turns westward and joins the
Ridge Wood tram near the dressing station at N.4.c.9.1.
These trams are in connection with Ouderdom light railway
system at Hallebast Corner, and it is proposed to connect with
it also at Gordon farm.
2. One line in each division area is being converted from
9-pound to 12 or 16-pound track as far as possible so as to take
3-ton trucks. The lines are Regent tram, Rossignol line, and
Ridge Wood tram (starting from Hallebast Corner). On Al-
berta line, 20-pound rails are being laid instead of the 9-pound
rails and will be carried on as far as possible up the Wytschaete
Road for the use of the vlight railways.
It is proposed to carry forward these four lines as soon as the
objective is reached, routes with easy grades having been
selected as follows:
Regent tram to be laid past Store farm, as near Spanbroek-
molen as the crater ‘will allow, between Rag Point and Hop
Point and adjoining with the existing enemy tram at N.30.d.971-.9.
Rossignol line to be laid just south of Petit Bois to join with
existing enemy tram at O.19.a.2.%.
Ridge Wood tram (Bois Carré branch) to be laid. The line
through Bois Carre will be laid through Bois Quarante to join
with existing enemy tram at O.7.d.3.4.
Alberta line will be laid on the existing meter-gauge sleepers
up the Wytschaete Road.
One company of Sixth East Yorks Regiment (Pioneers) has
been detailed to construct each of the above lines.

A. PRISONERS OF WAR.
DIVISIONAL COLLECTING CENTERS.
Prisoners will be handed over to the A. P. M., Ninth Corps, at
divisional collecting centers. Only weapons will be removed
before handing over except in the case of officers and N. C. O.’s,
who will be searched and all documents removed, under arrange-
ments made by divisional A. P. M.’s. Officers and N. C. O.’s are
to be kept separate from private soldiers. as far as possible.
CORPS CAGES.
Oflicers and N. C. O.’s on arrival at corps cage will be con-
lined in special pens. The remainder of prisoners will be ad-
mitted to pen A, when they will be formed up, counted, and
searched under arrangements to be made by A. P. M., Ninth
Corps. After searching, prisoners will be divided up into units
and passed into pen B for examination. After examination,
prisoners will be passed into pen C for evacuation to Second
Army cage at Bailleul under arrangements to be made by A. P. M.,
Ninth Corps.
An advanced corps cage will be established should the situa-
tion demand it.
WOUNDED PRIsoNERs.
Walking cases will be taken to divisional collecting centers
and forwarded to corps cage. Lying-down cases will be passed
80
NINTH ‘CORPS INSTRUCTIONS FOR THE OFFENSIVE. 81
in the ordinary manner to the casualty-clearing station, when
they will be examined under army arrangements.
B. DOCUMENTS.
All documents will be forwarded as quickly as possible to
corps headquarters. Maps, orders, and pigeon messages will
be dispatched to corps headquarters by special dispatch rider.
Arrangements will be made by divisions for a systematic search
of German corpses and for special parties to carefully search
headquarters and dugouts, each brigade detailing special men
for the purpose, who will be provided with a brassard.
Officer and N. C. O. prisoners will normally be searched at
divisional collecting centers, documents being placed in sacks
and dispatched with the prisoners to the corps cage. Private
soldiers will be searched at the corps cage. Documents will be
forwarded to corps headquarters from the corps cage for ex-
amination by a special oflicer at corps headquarters.
Immediately after prisoners have been searched their money
and valuables will be returned to them.
C. EXAMINATION OF PRISONERS.
An examination of afew specially selected prisoners will be
carried out by divisional intelligence oflicers at divisional col—
lecting centers on points of immediate tactical interest. No
additional staff will be provided from outside the division for
examination purposes at divisional centers. It is undesirable
that a lengthy examination should be carried out at divisional
centers and the dispatch of prisoners to the corps cage must
not be delayed.
Prisoners who have been examined at divisional centers will
be labeled with a special label, which will be provided for the
purpose, and forms will be issued upon which to record the
results of the examination, a copy being forwarded with the
escort to the corps cage to facilitate further examination.
Intelligence officers, assisted by German-speaking N. G. O’s.,
will be on duty continually at the corps cage. Information ex-
tracted of immediate interest will be telephoned direct to the
division concerned and afterwards to corps headquarters.
Specially selected prisoners will be detained at the corps cage,
and divisions requiring special information will send their
10049°—17-———6
82 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
divisional intelligence officers to obtain it or ask the intelligence
officers on duty at the cage to obtain it for them.
It is very important that early information should be obtained
of identifications. Brigade intelligence officers should, when pos-
sible, wire in to divisions and repeat to corps identifications ob-
tained. By this means very much earlier information of a
change in the enemy’s dispositions will be obtained than by wait-
ing for the arrival at divisional collecting centers.
D. AEROPLANE PHOTOGRAPHS.
Aeroplane photographs will be issued on the following scale:

R. F. C. dispatch rider will return via Mont Noir and will deliver
photographs for remaining formations at corps headquarters for
dispatch through Signal Service.
Reprints of photographs will not be demanded,. but photo-
graphs considered by formations to be of sufficient value to
warrant reproduction in large numbers will be demanded in the

usual manner through corps headquarters and will be printed
at Hazebrouck by army printing and stationery service.
Instructions for demanding aeroplane photographs as con-
tained in Ninth Corps I. G. 545 of May 8 will hold good.
E. ISSUE OF MAPS.
1/20000, 1/10000, and 1/5000 maps will be issued direct to
formations by Second Army on a scale laid down in Second
Army I.G.51, dated May 14, forwarded under Ninth Corps
I.G.588 of May 15.
Staffs of formations are responsible for seeing that units
have correct issue.
1/10000 special sheets will be issued to No. 53 Squadron,
R. F. C., for contact patrol work.
I Trenches requiring names, both in our lines and the enemy’s,
will be named by corps. Divisions wishing to give a trench any
particular name will notifyv corps headquarters as early as
possible. .
A situation map on a scale of 1/20000 or 1/ 10000 will be
issued each night showing the situation at 5 p. 111., and any
important information secured during the previous 24 hours.
An intelligent summary will accompany the map. As this
information may influence the following day’s operations, it
' is important that it should be passed down to lower formations
and units without delay.
APPENDIX XI.
EMPLOYMENT OF TUNNELING COMPANIES ON DUGOUTS AND
ROADS.
1. One. hundred and seventy-fifth, Two hundred and fiftieth,
and First Canadian Tunneling Companies will be employed in
the corps area.
2. Three officers and 30 other ranks from each company, pro-
vided with the necessary maps of the enemy trenches, will
reconnoiter captured dugouts as soon as the objective is reached.
One hundred and seventy-fifth Tunneling Company will
work in Thirty-sixth Division area.
Two hundred and fiftieth Tunneling Company will work in
Thirteenth Division area.
First Canadian Tunneling Company will work in Nineteenth

quired by the controller of mines) will work under the chief
engineer in reliefs on the repair of roads, as follows: ‘
One hundred and seventy-fifth Tunneling Company on Will-
verghem-Wytschaete Road.
Two hundred and fiftieth Tunneling Company on Kemmel-
Wytschaete Road.
First Canadian Tunneling Company on V ierstraat—W yt-
schaete Road.
' The roads will be roughly repaired to carry 60-pounder guns
and 6-inch howitzers, and will be pushed through as quickly as
possible by filling shell holes and making plank roads around
craters or over pulverized ground.
There will be no working party available to assist the tun-
neling companies on Zero day, but if the situation allows, work-
ing parties will be. detailed for the following days.
4. The corps roads officer will carry out the work of properly
reconstructing these roads.
5. Dumps of 2% to 3—inch planks, stone, decauville track, and
tip trucks are being made at T.5.b.%.3, Lindenhoek, Parrain

Center division, M26.c.4.3.-M.26.c.9.3.
Left division, R.5.c.2.2.
Reserve division, X.11.c.4.9.-—X.11.-d.1.5.
Should the sites suggested above for the three divisions in
front area not be considered suitable, companies of the train
will proceed to their own lines after drawing in bulk at railhead,
and there make up loads into detail issues for delivery at unit
transport lines, as no other sites in the corps area are available
as supply refilling points. ,
3. Divisions will arrange to have supply refilling points (if
used) marked-—
' Divl. R. P.
Supplies——
and the spaces allotted to brigat'le groups labeled——
Bde. Group.
4. Divisions will arrange for the widening of roads or the con—
struction of turning points, at divisional refilling points, also

88 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
for the erection of shelters, and any .other improvements which
may- be considered necessary. ’
.5. Supplies for corps troops will be drawn by supply column
from railhead. _
Divisions will draw by train transport. ,
Detail issues will be delivered from refilling points to unit
transport lines by vehicles of the divisional trains and thence
to units by regimental transport.
6. For routes for supply vehicles see Appendix E.
7. In addition to—
(a) The iron ration on the man.
(1)) The current day’s ration.
Authority is given for the following rations to be held:
(0) One day’s preserved meat and biscuit in support-
ing points for the maximum ‘garrison.
(d) One day’s iron ration for all troops within a pos-
sible enemy barrage. , '
(e) Two complete days’ rations for all'troops within
a possible enemy barrage.
Rations under (d) and (e) must be consumed by the end of
A day. - '
Rations under (0) will be retained for consumption on a lat‘-
ter date to be subsequently decided by the corps commander.
8. Divisions will arrange for the provision of cover "from
weather and, if possible, from shellfire, of rations dumped in the
forward area. ' .
Storage for rations mentioned under paragraph 7 (cl) should
‘be arranged at or near the headquarters of the battalions in
whose charge they will be. .
9. The rations referred to in paragraph 7 (6) will not be
drawn till about 10 days before Zero.
10. The object of permitting these dumps is to’obviate the
necessity for sending up rations during the bombardment when
the enemy may put down a barrage. ' '
11. The B. G. H. A. will notify divisions direct of the number
of rations required under paragraph’ 7 (o) by the heavy and _
siege batteries rationed by them in sufficient time to admit of
the rations being sent up for dumping.
12. (a) The earliest intimation possible should be sent to
the D. D. S. and T. by wire of the date it is intended to con-
sume the rations referred to in paragraph 7 (c), (d), and (e), in
vorder that the consignments to railh'ead from bases may ‘be
adjusted.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 89
(1)) Similarly, the earliest possible notice must be given of
any change from fresh to preserved rations desired during the
oifensive, so that orders may be made on the base accordingly.
13. For Kemmel defenses, one day’s preserved meat and his-
cuit for 4,000 men are stored as follows:
At Winnipeg, ' N.26.a.8.9, 2,000.

At Montreal, N.26.c.5.5, 1,000.
14. As soon as the number of rations ‘to be dumped under
paragraph 7 (c), l (d), and (e) have been definitely decided,
divisions will prepare lists on the proforma Appendix F, showing
the numbers of rations dumped under each heading, and will
forward five copies to corps headquarters.
Divisions will also forward one map numbered Q2, scale
1/ 20000, on which Will be shown the location of all strong points
and other places at which rations have been dumped.
15. A Ninth Corps heavy artillery train company will be
formed for the supply of heavy and siege batteries attached to
the Ninth Corps for operations.
This company will be administered by officer commanding E
supply column, and divided into two sections, A and B, which
I will be located as follows:
A section at S.8.c.4.8.
B section at M.16.a.3.6.
16. Each section will consist of--
1 ofiicer.
4 N. C. O.’s.
2 issuers.
1 loader For each heavy and siege artillery
1 G. S. wagon} battery supplied by the train.
Lieut. J. H. W. Hutson, A. S. C., will command A section;

90 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
18. The personnel and wagons referred to in paragraph 17
above will report at 4 p. m., May 25, rationed for consumption on
May 26.
Officer commanding E supply column will notify B. G. H. A.
and divisions direct as to the sections which the wagons are to
join.
19. The system of supply will be as follows:
(i) All heavy and siege batteries with the Ninth Corps will
be attached to the Ninth Corps troops supply column for rations
for consumption on May 27.
(ii) The officer commanding E supply column’ will arrange
with the officer commanding E siege park as to the numbers of
lorries required for the supply of the heavy and siege batteries.
(iii) Rations will be delivered by lorry at refilling points
near the camps of the sections of the heavy artillery train com-
pany, where a detail issue will be made and rations distributed
from there by G. 8. wagon to H. A. G., headquarters, and bat-
teries, the loaders acting as guides.
(iv) H. A. G., headquarters, and batteries will send A. B. 55
to the officer commanding section to which they are attached for
rations.
20. All batteries located south of an east or west line through
Parrain farm—Au Luxembourg Cabaret will be attached to A
section, all north of the above line to B section.
3. AMMUNITION.
1. A map showing existing and proposed railways for use in
ammunition supply during offensive operations has been for-
warded to all concerned under Ninth Corps No. Q.1848/11 of
27.3.17.
This map will be numbered Q. 3.
2. Two advanced ammunition railheads from which the Ninth
Corps area will be supplied with ammunition are being con-
structed at—
1. Duke of York, sheet 28.S.W., 8.15.1).
2. Fuzeville, sheet 28'.N.w., (4.3541.
The latter is to replace Ouderdom, which is considered too far
forward to be suitable.
3. No ammunition will be stored at advanced railhead itself,
but specially constructed sidings known ‘as “transit depots”
are being built, at which ammunition which can not be sent up
direct by rail to the guns will be stored. The transit dumps
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 91
for Duke of York will be in S.27.a., that for Fuzeville in M.9.a.
and b.
4. Rolling stock bringing ammunition from the base will not be
allowed forward of the Duke of York and Fuzeville, respec-
tively. On the arrival of an ammunition train at either of these
railheads the ammunition will either be—
(1) Transferred into special broad gauge rolling stock or
600m. trucks, as the case may be, and dispatched
direct to ammunition refilling points or group sta—
tions (in the case of heavy artillery these will be
close to the gun positions) ; or
(2) Sent into the “ transit depots ” referred to in paragraph 3
above and there dumped until required.
5. Daily ammunition demands from formations will be met by
issues from ammunition arriving at advanced railheads by train
from the base or from stock in reserve at transit dumps.
6. All ammunition for heavy and siege guns will be sent up by
rail to sidings in rear of artillery groups, and from thence to
the guns by Decauville or trench tramway track.
These sidings are called “group stations.”
7. As much field-gun ammunition as possible will be sent up
by rail to the guns on a similar system to that outlined for heavy
and siege guns. Ammunition for groups of guns not accessible
to rail will be delivered at divisional refilling points and thence
by horse transport to batteries.
8. As much trench-mortar ammunition, grenades. S. A. A,
Very lights, and rockets, etc., as trucks can be found for on
trench tramways will be sent up by broad gauge or 60 cm. to
trench tramheads and there transferred to french tramway for
- dispatch to brigade dumps. The balance will be sent to divisional
refilling points accessible for road and rail for dispatch by horse
transport.
9. The intention of these railways is to take as much trans-
port as possible off the roads. They will therefore be used to
the limit of their capacity.
1.0. If the demand on advanced railways is greater than their
capacity, S. M. T. 0., Ninth Corps, will arrange for the pro-
portional distribution of available trnckage between the various
services in such a way that no service is completely shut down
at any time for want of trucks.
11. Any balance of stores will be carried by road transport.
92 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
12. Labor for handling ammunition will have to be found at
the following points:
(a) Advanced railhead.
(1)) Transit depots.
(c) Refilling points, both road and rail.
(d) Trench tram heads.
(e) Gun positions.
(f) Infantry brigade dumps.
Labor units are to be provided by the army for (CE) and (b) ;
(e), (d), (e), and (1‘) will be found by the troops. Divisions
and B. G. H. A. will arrange for the provision of these parties.
In the meantime divisions and B. G. H. A. will be prepared
to find labor at their own refilling points and tram heads.
13. A. The system of supplying ammunition to batteries will
be as follows:
(1') By rail to group stations—(a) To batteries located suffi-
ciently close to a group station for ammunition to be carried,
by train direct from railhead.
(b) To batteries located on a trench tramway system which
will take light railway stock, ammunition will be taken to the
most convenient group station and thence (in the same wagons)
by mule or other traction to the battery.
(0) For batteries served by the light railway, but too far
from it for ammunition to be carried by hand to the battery,
ammunition will be sent ‘to the nearest group station and thence
by light trench tramway trucks along trench tramway track,
to be laid under arrangements by the B. G. H. A. or divisions
to the batteries.
(d) Ammunition for batteries served by the broad-gauge rail-
way will be sent to group stations and there either transferred
to trench tramway systems, connected with it or transferred
to specially laid trench tramway track to the guns.
(‘i/1'.) By rail to divisional refitting points—(a) For batteries
not on the trench tramway system.
(b) In case of a breakdown of the railway forward of the
refilling point, ammunition for all field guns and trench muni-
tions will be sent to divisional refilling points and thence by
horse transport under divisional arrangements.
(tit) By road from advanced ratZheada—(a) Requirements
in excess of the carrying capacity of the railways.
(7)) In event of a complete breakdown of the railway system.
(c) For siege batteries not accessible by rail.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 93
B. Supply of S. A. A., grenades, T. M. ammunition, rockets
and flares, eta—Trench munitions can be sent by rail to trench
tram heads as follows:
(i) Right division—Lindenhoek (L1. or L2.)
or
, Kemmel Chateau (15.43.).
Center division—Kemmel Chateau (K.4.c.)
or
Parret farm (K.3.E. ) .
Left division—Hallebast.
Whence they will be conveyed under divisional arrangements
by trench tram to divisional brigade bomb stores. ‘
(ii) To divisional refilling points, from where they will be
conveyed under divisional arrangements by horse transport as
required.
C. Ammunition railheads serve areas, not particular corps.
These railheads will be in charge of army railhead stafis, the
labor being provided by labor units.
D. Each corps having guns in an area served by an advanced
ammunition railhead will have a representative at that rail-
head. Representatives of the Ninth and Second Anzac Corps
will be stationed at the Duke of York. Representatives of the
Ninth and Tenth Corps will be stationed at Fuzeville.
E. The duties of the corps representative at advanced am-
munition railhead will be—
(i) To check the trainloads for the refilling points and group
stations served from his railhead and see that they are ‘cor-
rectly labeled for their destinations. Labels will be supplied
by army headquarters.
(ii) To inform the ofiicer in charge of each group station or
' refilling point (the consignee) of the dispatch of the train from
railhead.
(iii) To see that the guard of the train is given a waybill
for stores loaded. This waybill will be in a sealed envelope
addressed to the consignee.
(iv) To keep a tally of all ammunition taken on charge of
the corps during the day and report the amounts of each nature
taken on charge to E ammunition park twice daily at stated
hours.
(v) In event of sufficient trucks not being available to send
up all the ammunition demanded, or of a breakdown on the
railway, he Will at once inform— _
(a) The group station oflicer or officer in charge of the re-
filling point.
94 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
(b) The B. G. H. A., Ninth Corps, or the division concerned.
(0) 8. M. T. O. (in the case of heavy or siege gun ammuni-
tion he will repeat to E siege park) the number and
nature of rounds which will have to be sent by road
and the time and place at which lorries are to collect.
F. The 8. M. T. O., Ninth Corps, will arrange to detail an
oflicer as corps representative at the Duke of York and Fuze-
ville, respectively, together with a staff of one N. C. O. to act as
clerk and two privates to act as checkers at each place.
G. The B. G. H. A. will detail an ofiicer to be in charge of each
group station from which heavy and siege guns are supplied
with ammunition.
As soon as all group stations are decided on, vide Ninth Corps,
No. Q/ 1848/ 33 of 16.4.17, the B. G. H. A. will work out proposals
as to the numbers of officers, N. C. O.’s, and men which will be
required for dealing with the ammunition supply of heavy and
siege guns at group stations in the corps area and submit his
proposals to corps headquarters for approval. The necessity for
the men having to work in shifts night and day must be borne
in mind when estimating the requirements for Working group
stations.
H. Divisions will detail an officer to be in charge of each group
station and divisional refilling point serving their guns.‘ As
soon as group stations for the supply of field guns have been
fixed (vide Ninth Corps, Q/ 1848/33 of 14.4.17), divisions will
work out their requirements in officers, N. C. O.’s, and men for
working their group stations and divisional refilling points and
submit their proposals to corps headquarters for approval.
I. The duties of officers in charge of group stations and divi-
sional refilling points will be—
(i) To be responsible for the supply of ammunition from group
stations to gun dumps.
(ii) To keep an account of all receipts and issues of ammuni-
tion at their group station or refilling point and render a return
daily to divisional headquarters or to B. G. H. A., as the case
may be, showing the amounts of each nature received and issued
and required to be sent up. .
(iii) To superintend the unboxing of ammunition and insure
that empty boxes and cartridge cases are loaded on returning
trains and not allowed to accumulate at refilling points.
Empty boxes and cartridge cases will be packed in complete
truck loads and not distributed in small quantities all over the
train.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 95
(iv) To see that labels are removed from trucks as soon as
they have arrived at their destination.
(v) To return way bills by the guard of the train.
(vi) He will be personally responsible for the prompt clear-
ance of loaded wagons. One hour should suffice to unload and
reloadv with empties a normal group-station train.
Any wagons not cleared within this time are liable to be re-
moved with their load. When wagons go beyond a group station
on to a trench or battery tramway time will be allowed for the
- journey; but the group-station officer is not relieved of his re-
sponsibility for the. prompt release and return of the wagon.
The prompt return of rolling stock is a matter of supreme
importance; the capacity of the advanced railways is directly
governed by it, and any slackness in this respect will seriously
jeopardize the supply of ammunition and stores.
(vii) On being informed by the corps representative at rail-
head that a breakdown on the railway has occurred, or that am-
munition is to come up by road, he will, in the case of heavy or
siege artillery, inform the batteries concerned that they must be
prepared to take delivery of ammunition by lorry and repeat
the information to the heavy artillery group concerned. In the
case of field artillery he will notify the division concerned. ~
(viii) If it is necessary for trucks to be hand shunted at a
siding he will be responsible that proper precautions are ob-
served and that trucks are not allowed to run onto the main
line or to foul the points.
(ix) In event of the batteries served by his group station mov-
ing, he will inform the corps representative at railhead if the
group station is no longer required, and repeat the information
to A. D. A. S., Ninth ‘.or'ps, if he has a telephone on charge.
(x) He will see that the unloading parties close the flap doors
of empty wagons before leaving the train.
K. The following telephonic communication will be necessary
in connection with ammunition supply and accounting:
Corps headquarters ______ __To ammunition‘ railhead (Duke
‘ of York, Fuzeville).
To right, center, and left divi-
sions and B. G. H. A.
To divisional refilling points.
To group stations.
96 NINTH'CORPS INSTRUCTIONS FOR THE OFFENSIVE.
Divisional headquarters____To artillery group or brigade
_ headquarters.
To divisional refilling points.
To divisional group stations.

B. G. H. A To H. A. group headquarters.
To group stations.
Group stations To ammunition railhead.

(i) The G. O. C., R. A., will inform E ammunition park by
12 noon on Z7 day as to the ammunition which he estimates
will be required to replenish the guns on U day; and thereafter
daily at 12 noon how much ammunition will be required for re-
plenishment 48 hours in advance, stating the proportions of
each nature required to be supplied from Duke of York and
Fuzeville, respectively. Similarly, divisions will telegraph to
reach E ammunition park daily by 11 a. In. their probable re-
quirements in S. A. A., trench-mortar ammunition and grenades,
stating from which railhead delivery will be required. 0. C.
E ammunition park will telegraph this information to Second
Army headquarters before 1 p. In. daily.
(ii) B. G. H. A. and divisions will arrange for demands for
ammunition required from 12 noon to 12 noon from advanced
railhead, to reach E ammunition park by 9 a. m. daily, stating
the exact amounts of each nature required at each group sta-
tion or refilling point. These demands will be repeated to Ninth
Corps headquarters and G. O. C., R. A., Ninth Corps, for infor-
mation. ‘
Demands after being checked .will be forwarded by E ammuni-
tion park to the‘corps representative at the railhead concerned,
who will arrange with the railhead ordnance officer for the load-
ing of the ammunition and with the railways for its dispatch.
In event of suflicient rolling stock not being available, the
corps representative at railhead will immediately inform
S. M. T. O. of the number of lorries required, for delivering am-
munition. - I
Urgent demands for ammunition or transport can be made at
any time.
M. Unless otherwise arranged by corps headquarters, the for-
mation by which guns are tactically controlled will be responsi-
ble for the supply of and accounting for their ammunition.
N. In special cases, such as a battery belonging to the Tenth
Corps, located in the area supplied by the Duke of York, at
which railhead the Tenth Corps will not ~have a representative,
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 97
the Tenth Corps will be responsible for the supply of and ac-
counting for the ammunition of this battery.
0. (i) From the commencement'of the bombardment two ex-
penditure wires will be sent'daily to E ammunition park and
repeated to Ninth Corps headquarters for information.
(a) Expenditure between 11 a. m. and 7‘ 1). 12a, to reach
corps headquarters by 8 p. m.
(b) Expenditure between 7 p. m. and 11 a. m., to reach
corps headquarters by 12 noon.
(ii) In event of the heavy artillery or a division being unable
to give an accurate report at the appointed hour, the expendi-
ture will be estimated, the necessary deduction or addition being
made by the heavy artillery and divisions in the next telegram
to be dispatched.
The greatest care must be taken that expenditure as stated in
(a) is not included in (b), and vice versa.
(iii) It must be thoroughly impressed on all concerned that
to enable the supply of ammunition to be maintained regularly
and a correct distribution effected, early and correct information
as to expenditures is essential.
Undue accumulation at the guns means the locking up of am-
munition which may be urgently required elsewhere, and undue
depletion of gun dumps may lead to urgent demands which
might be very diflicult to meet, especially from a traiiic point
of view. Too much attention, therefore, can not be paid to in-
suring that the dumps at the guns are carefully watched and
regulated according to the circumstances at the time.
P. Any difiiculty or delay in getting ammunition to the guns
will be reported at once by divisions or the Ninth Corps H. A.
to corps headquarters.
14. In event of a breakdown in‘ the railway service it may be-
come necessary to employ lorries for drawing ammunition from
the Duke of York or Fuzeville siding and delivering it in the case
of siege artillery at the nearest point 011 the road to the guns;
in the case of field gun and trench munitions to divisional re-
filling ‘points.
15. For scales of ammunition available for operations, see
Ninth Corps Instructions for the Offensive, Part 1, General Staff,
Appendix, and Tables A and B.
4. MEDICAL.
1. Collection of wounded to regimental a/ld posts—By regi-
mental stretcher bearers, aided by such T. U. men, pioneers,
10049°-17—-—7
98 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.-
bandsmen, or others as G. O.’s C. of divisions may detail. Each
unit is responsible for bringing its own wounded back as far as
its own aid posts.
If circumstances admit, such extra assistance as is possible
will be provided from army or corps troops. Men detailed to
assist regimental stretcher bearers, whether from army, corps,
or divisional sources, will be held in readiness under divisional
arrangements at brigade headquarters, where early information
as to number of casualties will be available.
The regimental aid posts on the present front are:
Right sectoi'-—N.35.c.3.8, Cooker’s farm.
N.29.c.3.0
N.29.c.3.3
Middle sector—N.23.c.10.4, off via Gellia.
N.23.a.8.8, ofi Rossignol Road. '
N.17.d.4.6, off Watling Street.
Left sector—N.11.a.7.6, Brasserie on 7.
N.6.a.1.1., Brasserie on Vierstraat-Ypres Road.
Most of these aid posts average about 600 yards from the
present front line, so the carry can be done in one relay. Later,
in the event of a successful advance, fresh regimental aid posts
would have to be improvised on or beyond the present front line.
The carry back from the new to the old regimental aid posts
would be done by field ambulance personnel, under arrange-
ments to be made by O. C.’s advanced dressing stations.
2. From regimental aid posts to advanced dressing stations.—
The present regimental aid posts are all situated on commufl
nication trenches and on or near trench tramways. Evacuation
from these points to advanced dressing stations will be by
R. A. M. C. personnel of the field ambulances. It will be done
as much as possible by trench tramways, rolling stock and
mules for traction to be provided by the divisional trench tram-
way office-r. .
The advanced dressing stations are—
Right sector—Lindenhoek, N.27.d.0.8, holding 80.‘
Middle sector—Kemmel brewery, N.21.c.8.5, holding 150.
Left sector—Laiterie, N.16.d.1.4, holding 56. ’
Kleine Vierstraat, N.10.a.9.9, holding about 64.
These points are all placed so that both communication trenches
and trench tramways converge to them. They average 2,000
yards behind the front line. Here the wounded will‘ be re-
dressed if necessary, supplied with hot drinks and food, and
Regent dugouts.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 99
taken by the divisional motor ambulances to the main dressing
stations.
3. Use of trench tramwaya—Divisional trench tramway offi-
cers will be accommodated in or near the advanced dressing
stations.
They will be responsible that trolleys, with gate ends for
stretchers and mules to draw them, are kept supplied to the
regimental aid posts as fast as the number of casualties require
and the circumstances permit.
They will also be responsible that breaches in the line are
repaired as rapidly as possible.
For these purposes they will constantly cooperate with the
oflicers commanding advanced dressing stations.
During offensive operations instructions will be issued to all
concerned to allow free traflic of wounded along the tramways
at all times.
4. Main dressing stations.—
Right sector—Dranoutre, M.S6.c.3.2. 6 Nissen Bow Hos-
pital huts and canvas to hold 1.000.
Middle sector-—Locre Hospice, supplemented by canvas
to hold 1,000.
Left sector—Westoutre, the convent. supplemented, if
possible, by four hospital Nissen Bow huts and as
much canvas as can be got to hold, if possible. 1,000.
5. Evacuation to O’. (7. S.—
From right and middle sectors to Bailleul.
From left sector to Remy siding. all by No. 5 M. A. C.
on the continuous-chain principle.
6. Divisional collecting posts for walking wounded.—
Right sector—-N.31.c.3.5.
Middle sector—M.24.d.3.8.
Left sector—N.10.a.9.9. Wounded will converge on
these points from the front by cross-country tracks
which have been reconnoitered and will be marked
with Red Cross guiding flags and box lanterns.
Cases from these points will be transferred by horse trans-
port, busses, and lorries, as well as by the M. A. C. to the
C. C. S.’s.
The broad-gauge and light railways will be taken full advan-
tage of in the evacuation of wounded. Wounded can, however,
only be evacuated to or short of the point to which the rolling
stock is returning in the normal course of events. Returning
supply and ammunition trains will be used whenever available;

7. Corps rest statiom—The site at S.9.d.9.9, at present occupied
by one hundred and ninth field ambulance, Thirty-sixth Divi-
sion, together with the camp at S.10.d.4.9, Keersebroom, lately
occupied by Twenty-ninth Prisoner of War Company, Will be
opened as a corps rest station; accommodation, about 500.
8. I ncrcaso of strcTchcra—The total of stretchers per division
will be increased prior to operations to 1,000. This figure will
not include stretchers now on charge of battalions nor the
present allotment of 21 wheeled stretchers per division.
5. VETERINARY.
1. Mobile veterinary sections of divisions will be located as
follows:
Right division, M.35.c.3.4.
Center division, l\I.26.b.8.8.
Left division, M.9.a.2.5.
Reserve division, S.1.b.1.4 and at railhead.
At these points, horse collecting stations will be formed, and
sick and Wounded horses Will be cleared, under direction of
A. D. V. S. of divisions.
Marching cases being sent by road, nonmarching cases by rail.
2. Marching cases by road to—
No. 7 sick-horse halt near Mont des Cats (sheet 27.
Q.24.b.4.1) .
No. 8 sick-horse halt near Staple.
No. 23 veterinary hospital, St. Omer.
Marching is only practicable where the number does not ex-
ceed the normal (1 per cent per week). In excess of this number
it will be obligatory to employ transportation by rail or canal.
The arrangements, foraging, etc., of sick-horse halts are made
by the D. D. V. S., Second Army.
One mounted man should not lead more than six horses, ar-
ranged in pairs, one behind the other.
3. Special sick-horse trains—Horses will entrain at Haege-
doorne.
Arrangements for trains will be made by the D. D. V. S.,
Army, with the A. D. R. T.
Forty-eight hours’ notice will be expected and given. Trains
Will consist of a minimum of 25 trucks; i. e., suflicient accommo-
dation for 200 L. D. or 150 H. D.
The reserve division will be prepared to place its mobile
veterinary section under the orders of the D. D. V. 8., Second
NINTH CORPS II‘TSTRUCTIONS FOR THE OFFENSIVE. 101
Army, if he requires it. It would be placed near the entraining
railhead at Haegedoorne to receive, superintend, and conduct
the entrainments.
If this measure is ordered, the officer commanding the mobile
veterinary section of the reserve division will arrange with the
R. S. O. for the provisioning of the men and horses under his
charge.
4. A. D. V. S. of divisions will send D. D. V. 8., Second Army,
a daily telegraphic statement showing number by classes of (A)
marching cases, (B) rail cases, (0) cases retained for treatment.
6. TRAFFIC CIRCUITS.
1. Routes have been laid down for the following:
((1.) Supply vehicles from their standings to railheads, and
thence to refilling points. Appendix E.
(1)) Motor ambulances. Appendix G.
2. A map showing the roads which motor vehicles are allowed
to use, and the directions to be followed during operations is
attached. Map Q4.
3. As a general principle, horse-drawn vehicles must be kept
off motor routes whenever possible. Divisions will arrange for
the construction of cross-country tracks to enable this to be done.
(See “8. Road construction” of these instructions, para-
graph 5.)
4. A list of the signboards, etc., recommended for marking
roads and tracks will be forwarded to corps headquarters as
early as possible, to enable a proportion of these notices being
made in the corps workshops, the balance to be made by divi-
sions.
7. WATER SUPPLY.
DRINK IN G ‘VA TER.
1. A map (Q-5‘) showing the drinking-water supplies in the
Ninth Corps area, existing and under construction and proposed,
is attached.
It is considered that the administrative areas will be suffi-
ciently supplied when this supply is completed.
2. The schedule Appendix H gives the daily yield of each
station in gallons.
3. Water has been laid on by pipe line to the trenches which
should give a sufficient supply.
102 mnrn conrs INSTRUCTIONS ron THE OFFENSIVE.
Divisions will submit their proposals for——
(a) Supplementing this supply where necessary by petrol
tins, etc.
(b) Providing for the supply of water to the trenches in
event of the pipe-line supply being interrupted.
(c) To have a reserve of water immediately available in
the trenches in case of an advance.
4. As the water carts of units will be in constant daily use,
it is hoped that extra water carts may be allotted by the army
and placed under corps control. For use in event of a break-
down in any of the forward pipe-line supplies, these carts would
be kept full at convenient centers, such as Dranoutre, Locre,
and La Clytte, for use in case of necessity to deliver water to
dumps of petrol tins or tanks established on the line of the
Daylight Corner—Vierstraat Road.
5. It is hoped also that some lorries of an army water column
may be made available for the corps, as they would be a valuable
asset in amplifying the water supply in the corps.
These lorries would be used in event of an advance for deliv-
ering water to tanks as far forward as it is possible for motor
transport to proceed, whence it would be taken on by water
carts.
HORSE WATER.
6. Previous reconnaissances of the area tend to show that the
water supply should be sufficient during the summer months
for the number of horses which will be in the area- during con-
centration. It will be necessary, however, to take all possible
steps to arrange for the storage of water by the construction
of‘ dams in suitable places on streams. Ponds should only be
used when streams are not accessible.
Arrangements are being made by the corps to replace last
year’s dams, which were removed for the winter, as soon as it is
feasible to do so. Divisions will submit recommendations as
to any further dams which they consider may be required, as
well as any suggestions which they may have for conserving
the horse water supply.
7. No horse watering places are to be established on roads.
Arrangements must be made for each unit to water in its
own lines, or, if this is not possible, tracks must be made across
the fields from transport lines to horse watering places. Horses
are not to be taken along or across main roads to water.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 103
Divisions will take in hand at once the provision of extra
horse watering places, pumps, and troughs for the horses which
will be in their areas on concentration, and arrange for the
erection of signposts and notices which will enable incoming
units to find their way to horse watering places without diffi-
culty. Divisions will also consider the question of establishing
horse watering places at or near ammunition and supply refill-
ing points. and at suitable places oif tracks leading to the front
at which the horses of vehicles taking up ammunition and
supplies, etc., could be watered.
WATER SUPPLY IN FORWARD AREA.
8. (a) Right divisions—A water station is being made at
Lindenhoek Cross Roads, N.27.c.9.8. There is also a 4-inch pipe
line from a reservoir on Kemmel Hill, passing through N.27.a.
and b., N.28.a to N.28.b.9.4; from this 4-inch pipe line there
are 2-inch lines with standpipes -at Fort Victoria, N.28.c.2.6,
on the road at N.28.b.9%-; at Regent Street dugouts, N.29.c.4.3;
Newport dugouts, N.34.a.2.9; and Vroilandhoekn, N.28.a.9.3.
This is'known as the Kemmel forward supply. The 4-inch line
will- be extended to the Wulverghem—Wytschaete Road at
N.35.d.7.2, where there will be a standpipe.
(1)) Center division—Water stations exist at N.22.a.2.4,
N.21.a.6.0, and N.16.b.9.3 from the Scherpenberg Reservoir.
There is a standpipe from 2-inch pipe off Kemmel forward
supply at Alberta dugouts, N.23.d.4.7.
The Scherpenberg supply is being extended from N.22.a.2.4,
through N23 central, and will be eventually carried up to
Wytschaete, with standpipe near Irish House.
(0) Left division—A water station exists at the Brasserie.
N.6.a.1.1; this is supplied by a 4-inch pipe from Dickebusch
Lake. This is being extended through Bois Carre toward the
front line and will be eventually carried on toward Wytschaete.
with standpipe on the road in N.18.b. Standpipes and 400-
gallon tanks will be put in where the 4-inch pipe line crosses
the new reserve line (N.12.a.9.5) and at Western Redoubt
(N.12.a.7.9), also where it crosses the front line in sector N.12.2
as soon as it reaches there.
8. ROAD CONSTRUCTION AND REPAIR WORK TO BE DONE.

to Bus farm, N.33.d.3.1.' A considerable portion of this road
would be in Second Anzac Corps area. It is hoped, however,
that it may be made common to the Ninth and Second Anzac
Corps.
(f) Canada Corner to Kemmel. It is understood that this
is already being undertaken by the Second Army.
(9) From the Reninghelst-Canada Corner Road about
M.11.c.4.7.'to N.7.c.4.5., thence round West and south sides of

M26.d.3.3.), requires minor repairs.
5. CROSS-COUNTRY TRACKS.
In addition to the above, which will be carried out under army
and corps arrangements, divisions will prepare cross-country
tracks from rear to front of their areas for use by walking
wounded, prisoners of war, and reinforcements, and also by
horse transport as far as possible.
To avoid clashing, divisions will arrange that their own tracks
pass only through their own areas.
If it is considered unavoidable for a track to overlap into a
neighboring divisional area. reference will first be made to
corps headquarters (Q) .
A tracing of selected alignments for tracks will be furnished
to corps headquarters (Q) as early as possible.

advanced divisional dumps and thence to main divisional dump.
Every man of units returning from the trenches must bring
away something salved with him, an extra rifle or pick and
shovel, etc. Similarly, every wagon or lorry going back empty
is to be loaded with as much salved material as possible.

dumps by armorers, who will select and repair the best for re-
issue, while those in worse condition will be cleaned, oiled, and
returned to the corps dump, where they will be dealt with as
soon as possible. Surplus arms,'accouterments, and steel hel-
mets will be returned to the base.
All Lewis gun magazines salved are likely to be required for
reissue. They will be repaired as far as possible at divisional
dumps, or if too many to be dealt with the divisional armorer’s
shop should assist.
(c) Salved material not required for reissue to troops will
be evacuated at every opportunity by train.
(d) A. D. O. S. will be consulted by corps salvage officer as
regards the materiel to be reissued.
7. All clothing will be passed through to the corps dump with-
out examination. At the corps dump it will be carefully searched
on receipt, and all secret maps or documents removed. After
classification by garments, the clothing will be returned to the
base.
8. Driving bands should be removed from all shell cases found
and returned to the base as produce.
In salving articles, perishable things, such as unboXed ammu-
nition, fired grenades, food, etc., should be searched for and re
moved first.
9. Valuable stores, such as watches, compasses, and binoculars,
accumulate at main dressing stations and caualty clearing sta-
tions.
The corps salvage ofiicer will keep in touch with these stations,
and arrange to collect these articles periodically. If possible,
they will be repaired for reissue; otherwise they should be sent
to the base very carefully packed.

by E ammunition park, who will reissue what is good, and return
the remainder to railhead.
12. Trench munitions should be handled by salvage companies; '
bombs and grenades should be- dedetonated at once. All that is
good should be reissued and the remainder returned to railhead.
13. To form the staff of armorers required at the main corps
and divisional dumps, armorers will be withdrawn from divi-
sions except one per brigade. Each division-will send one to
their main dump and one to the divisional armorer’s shop. The
remainder will report at the corps dump.
15. STORAGE OF SPARE KIT.
1. Arrangements have been made with the town major, Bail-
leul, for accommodation for the storage of spare kit to be re
served as follows: '
Corps troops, 191 Rue de la Gare, Bailleul.
Thirty-sixth Division, 191 Rue de la Gare, Bailleul.
Sixteenth Division, 190 Rue de la Gare, Bailleul.
Nineteenth Division, 198 Rue de la Gare, Bailleul.
2. Before operations commence all articles which belong to
the division, but which do not come under any of the official head-
ings laid down in G. H. Q. letter, Q4380, 22.4.16, for collection of
stores in case of an advance, i. e., ordnance stores, A. S. C.
stores, R. E. stores, medical stores, veterinary stores, will be col-
lected in these places by divisions under divisional arrange-
ments; by corps troops under arrangements to be made by the
G. O. C., R. A., B. G. H. A., O. C., corps mounted troops, S. M.
T. O., Ninth Corps and camp commandant, Ninth Corps.
3. No ammunition, bombs, or explosives are to be placed in
these stores on any account. Divisions and the Ninth Corps
salvage officer will arrange for their stores to be properly parti-
tioned off among various formations and units, and for notices
to be put up showing the units, etc., to which the compartments
are allotted. Caretakers will be placed in charge of each store,
those for corps troops being found by the corps salvage section.
4. Adequate fire precautions are to be arranged for for each
store. '
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 115
16. CLEARING THE BATTLE FIELD.
1. The general principle will be that divisions will be respon-
sible for carrying out their own burials and for leaving a suffi-
cient party behind in the event of the division being relieved be-
fore the work is complete. '
This party will remain under the supervision of the corps
burial oflicer until he reports that the work ‘is as complete as
possible under the circumstances.
‘ It will then be ordered to rejoin its division.
2. Corps heavy artillery and units of corps troops will be simi-
larly responsible for carrying out their own burials under super-
vision of the corps burial officer. ‘
3. Burying parties should not be detailed from units which
are going into action. They will be found, whenever possible,
from units which are not engaged in the actual operations.
4. The Tenth Labor Company has been allotted to the corps
to assist in clearing the battle field and in burying the dead.
Parties will be detailed by Ninth Corps A, whenever possible.
to divisions, by whom they will be administered.
This does not in any way absolve divisions from responsibility,
as defined in paragraph 1.
5. No other personnel can be provided, and divisions should
have men detailed beforehand to carry out their burials.
6. An officer will be appointed by the corps and by each divi-
sion for duty in connection with burials only; he will be known
as the corps (or divisional) burial ofiicer, and will work in con-
junction with the corps and divisional salvage officers.
Capt. E. F. Fforde, Seventy-eighth Royal Irish Fusiliers, is
appointed Ninth Corps burial officer. His address is corps head-
quarters. '
The corps and each divisional burial oificer will have an N. C. O.
to assist him. Each divisional burial officer will, in addition,
have one N. C. O. with each brigade under his orders. (Divi~
sions will detail this personnel at once and report names of divi-
sional burial oflicers to corps headquarters.)
7. The corps and divisional burial officers must thoroughly
understand the procedure inconnection with burials and must
be capable of organizing for this purpose any party detailed.
Before and after an action they must reconnoiter personally and
collect information.
8. Copies of supplementary detailed instructions for corps and
divisional burial officers have been issued to all concerned (Ninth .
Corps A/372, dated 27-4-17).

140 NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
TRAFFIC ORDERS DURING OPERATIONS.
1. GenemL—The success of operations depends largely on the
uninterrupted passage of ammunition and supplies to the front
and of ambulances and empty vehicles to the rear. Corps and
divisions will arrange to allot roads to different classes of traffic
during stated hours.
Commanding oflicers are responsible that all ranks under their
command are made acquainted with these orders, which must
be rigidly enforced. They will deal personally with cases in
which they have been disobeyed.
It is the duty of all officers and N.C.O.’s to give every assist-
ance in their power to the M.M.P. and traffic-control posts.
2. Direction—On single traffic roads, traflic will move only
in the direction shown by the arrow heads on the traffic map.
Permission for any vehicle to move against the circuit will
only be given in cases of great urgency; it must be in writing
and bear the stamp of an ARM.
All MT. vehicles are to have a tracing of the circuit map
pasted up where the driver can see it.
No restrictions are placed on despatch riders.
Foot passengers and horsemen will move as far as possible
off the roads which must be kept clear for wheeled traffic.
3. Speed limits. The following speeds are not to be exceeded :



Vehicle. Open country. Motor cars . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . - 20 miles per hour. . 10 miles per hour.
Ambulances . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 miles per hour. . 6 miles per hour.
Lorries and busses . . . . . . . . . . . . . . . . . . . . . . .. 8 miles per hour--. Do.
Horsed transports 1 . . . . . . . . . . . . . . . . . . . . -. Wall. . . . . . . . . . _ . . Walk.


1 Except when in charge of an officer or hearing written orders from one to exceed
this pace.
4. illcchonical transport—All lorries and busses are to have a
lookout man stationed behind. He will arrange some means by
which he can rapidly communicate with the driver.
No lorry or bus is to pass another lorry or bus moving in the
same direction.
5. H alts.———Columns of troops are not to halt when passing
through towns or villages or when passing other halted traflic.
If a halt opposite other parked or haltedtraflic is unavoidable,
every endeavor must be made to leave the roadway clear.
NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 141
Crossroads and road junctions are to be left clear.
Gaps of not less than 20 yards will be left at frequent intervals
in columns, both on the march and at the halt, to allow of the
sidetracking of other traflic when the columns are halted. Warn-
ing should be passed down a column before halting.
When halted, vehicles are not to “ double bank,” and drivers
are not to leave their horses’ heads when dismounted.
If the halt is due to a block, an officer or noncommissioned
officer must be posted at the rear of the column to prevent traffic
following from behind in the same direction attempting to pass.
When approaching a block, all traffic will be pulled up 50 yards
short of it.
When possible, men and horses will clear the road and vehicles
will be pulled well into the right-hand side. If riding horses
can not be taken off the road, they will stand with their heads
toward the center.
Horses and vehicles awaiting their turn at standpipes. troughs,
refilling points, dumps, etc., are not to halt on the road, but will
form up in fields to be provided and marked under divisional
arrangements for the purpose.
6. Emcrcz'sing and watering 0f horses—No man is to be placed
in charge of more than two horses when exercising or watering.
Animals will not be exercised on the roads shown on the traffic
map. Divisions will arrange for special tracks to be made so as
to insure that roads are avoided as far as possible by watering
parties.
Whenever horses going to water have to use or cross a trafiic
road for the purpose, an otlicer will accompany them to insure
that traific is not delayed.

‘ APPENDIX N.
INSTRUCTIONS REGARDING THE DIVISION OF AREAS INTO
SUBAREAS.
1. Each divisional area will be divided into four sub-areas.
three of which will be arranged so as to be capable of accom-
modating an infantry brigade each in addition to such army
and corps troops as may be located in the area for operations.
The fourth area, which will be, roughly, west of the line Dra?
noutre-Locre-Reningheist, will be termed a “ horse-transport
area)’
2. It is not possible to lay down a hard-and-fast rule that all
transport lines shall be located in horse-transport areas; some
vehicles must necessarily be kept forward. It may also be
preferable in some cases for transport to remain with battalions
and in others for it to be kept in a horse-transport area.
It is left to divisional commanders to decide what proportion
of the various natures of transport shall be kept in the forward
areas.
In deciding the distribution of vehicles it should be borne in
mind that by keeping horses in the back areas not only are
watering facilities more easily arranged but also a large number
of vehicles of the train carrying forage can be kept oif the for-
ward roads.
3. The object in subdividing divisional areas is to facilitate
reliefs during operations.
Provision must be made for the relief of—
(i) The division as a whole.
(ii) The division less artillery.
(iii) The divisional artillery.
(iv) Army or other field artillery brigades.
(v) Heavy or siege batteries or groups.
(vi) Army or other'attached units, such as labor com-
panies, etc.,
and arrangements made that the relief of any of the above can
be carried without disturbing the remainder.
In‘ order to enable this to be done and to provide ‘for the
case of troops moving up in close support of the assaulting
10049°—-17-—-—10 . 145
146 . NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE.
brigades before the latter are relieved, areas to accommodate the
incoming units must be cleared before their arrival.
As far as the accommodation for the men is concerned, there
vshould be no difliculty in arranging for this; but since the trans-
port of troops already in the area can not be moved till they
leave, arrangements must be made to reserve. convenient fields
as staging areas for use by the transport of the incoming units
till their proper lines are vacated.
4. Divisional billeting schemes will be prepared with a view
to enabling any of the reliefs enumerated in paragraph 3 above
being readily carried out. It should be possible to hand over at
any time to a relieving division a schedule showing the total
billeting accommodation and the location of all units in the
divisional area, and to provide incoming units with exact in-
formation as to the location of and accommodation in the billets
or camps which they are to take over.
5. For map and billeting schedule of the reserve divisional
area of the Ninth Corps on concentration (the Schaexken area). >
See map Q-G and Appendix C of these instructions.
In addition to the two field artillery brigades of a division,
billeting areas have been defined in the horse-transport area of
the reserve division for two army or other field artillery brigades.
As it is probable that all the artillery of the reserve division,
as well as any extra army field artillery brigades allotted to the
Ninth Corps, will be in action from an early period of the con-
centration, and will consequently require wagon lines for a pro-
portion of their horses in the areas of the three divisions in the
line, vacant camps in the Schaexken area will be available for
occupation by horses of the divisional artillery of the forward
divisions, should it be desired to locate any of these in the
reserve area. ' ‘
On divisions informing the corps what horses and vehicles
they consider can be dispensed with in their own areas, accom~
modation in the Schaexken area will be allotted to them accord-
ingly.
6. The following numbers are allotted to divisions for their
subareas:

Right division _________________________ __ 1 t0 4
Center division_.__ ___ '_____ 5 to 8
Left division _ 9 to 12
Reserve division 13 to 16

NINTH CORPS INSTRUCTIONS FOR THE OFFENSIVE. 147
The corps troops area will be numbered 17 and the heavy
artillery area 18.
7. The subareas as defined for operations will be the same for
all administrative purposes. The names of P. B. and other
officers appointed subarea commandants are given in para-
graph 9.
These oflicers’ duties will be as follows:
(1) They should be acquainted with all the billets and huts
in their subarea and know exactly what work is being done. and
what it is intended to do, so that whenever one unit takes over
from another there may be absolute continuity of work.
(ii) Under instructions from divisions, see that every pre-
caution is taken in huts to guard against fire. Reports being
made, as necessary to the Q. staff of divisions on the subject.
(iii) Make arrangements to have notice boards put up show_
ing (.lrinking, horse-watering places and washing places, and the
marking of accommodation of each billet.
(iv) Looking after all unoccupied huts, horse standings, water
arrangements, baths.
(v) The making and keeping up to date an inventory of all
stoves, lamps, buckets, and other barrack stores and R. E.
stores, including laundry machinery of all kinds in camps, hut~
ments, and billets and to supervise the handing over of stores
between units on reliefs.
In event of an advance they will remain in charge of their
subareas and superintend the collection of surplus stores under
the divisional salvage officer.
Divisions will also arrange for barrack wardens to be de-
tailed to remain in charge of each camp of huts or tents. They
will be in charge of all Government stores in their camps and
act as guides to incoming units.
8. Divisions will submit to corps headquarters a map on a
scale of 1/10000 showing the division of their areas into num-
bered subareas and giving the location of all camps. billets.
horse lines, and staging fields in each subarea.
Attention is drawn to the conventional signs in use in the
Ninth Corps. copies of which are attached.
