G all units in normal field order. 34 ENGINEER TRAINING MANUAL—VIII. REMARKS. 34. Time distribution .—With the exception of officers and enlisted men engaged on routine work and instructors not needed in their normal functions as officers and noncommis¬ sioned officers, the entire command will be engaged at any time on one of the following groups of work: (1) Any one of the subjects (1) to (6) included under B—“ General service training,” the mounted men either at¬ tending mounted drill separately or with the balance of the command, mounted or on foot. (2) The schools under C, “ General service training,” and under D, “ Engineer training.” (3) General engineer training, by section (E 1, 2, and 3) or by company or battalion (E-4). (4) Subject G .—Practice marches and field exercises for the entire command. The instructors’ school will be held in the evenings and during calisthenic and other drills which require only a few instructors. Time for administrative work and the planning of drills is available during the periods assigned for the schools and other special instruction. 35. Instructors .—The total number of special instructors required is: (1) For general Infantry instruction (B-4), 6 officers, 6 noncommissioned officers. (2) For mounted drill (B-7), 2 officers. (3) For schools in general service training (C), 6 officers and about 10 noncommissioned officers. (4) For schools in general engineer training (D), 12 officers and about 16 noncommissioned officers. Of these four groups of work needing special instructors, only the schools in general service and general engineer training are held simultaneously. The total number of in¬ structors required for these schools is 18 officers and about 26 noncommissioned officers, and these instructors are available to serve as instructors in the work held at other times. Therefore, the total number of special instructors need not exceed 18 officers and 26 noncommissioned officers. ENGINEER TRAINING MANUAL—VIII. 35 exclusive of the 2 majors. The 2 battalion adjutants, the topographical officer, at least 2 of the medical officers, the 2 color sergeants, the sergeant bugler, the battalion sergeant major, and at least 9 of the 11 master engineers are available for duty as special instructors so that only 13 offi¬ cers and 12 noncommissioned officers need be drawn from the companies. It is thought that lieutenants will be found who are qualified for this work, which will leave all the captains and 5 lieutenants free for other duties during the periods designated for school work. Further, as the general In¬ fantry instruction (B-4) is conducted by the companies in rotation, only 2 officers need be drawn from the companies as special instructors in this work, leaving all the other com¬ pany officers free to participate in the work with their commands.

Special days will be set aside for practice marches and field exercises. 37. Guard and fatigue .—The rudiments of interior guard duty are to be taught under subject B-4-a, and not in con¬ nection with actual guard duty. Until two companies have ENGINEER TRAINING MANUAL—VIII. 37 had this instruction, guard will be performed by watchmen permanently detailed on special duty under an officer de¬ tailed as provost. Thereafter a regular interior guard will be established, assumed as not to exceed an officer of the day, 1 officer of the guard, 2 sergeants, 3 corporals, 36 pri¬ vates, and 2 buglers. In order not to interrupt class work unduly, the guard should be made up of details from all companies, the size of the detail from each company being in proportion to the strength of the company. The rosters should be so arranged that the officer of the day and the officer of the guard are not both special instructors. This permits the one who is a special instructor to attend his regular classes, his responsibilities as a member of the guard devolving on the other. Both should be excused from all other training. The guard will be excused from all duty except fatigue on the day after they march off. If the morning period for police is used properly by the companies, no additional fatigue details should be necessary. With the exception of the guard and old guard, only the following need be excused from drills: Lieutenant colonel and regimental staff (attend only when detailed as instructors), company commanders, first sergeants, mess sergeants, supply sergeants, and clerks from first period, third period, and fourth period (and clerks from sixth period) when absolutely necessary; special instructors from first, third, and fourth period work when not instructing or attending classes as students; two kitchen police and one orderly from each company by roster daily (orderlies at headquarters to be furnished by the guard); cooks, from all drills except cooks’ schools, a. m. Infantry drill and field exercises.

A-l and A-2. Regimental and company .—Texts: Army Regulations; Compilation of General Orders, Circulars, etc.; Appendices 1, 2, and 3, Engineer Training Manual; Manual for Courts-Martial; War Department General Orders and Circulars; and Special Regulations of War Department Bureaus. ENGINEER TRAINING MANUAL—VIII. 53 Purpose: To instruct all officers and selected enlisted men in their duties incident to regimental and company adminis¬ tration. Methods of instruction: ^Instruction will be given by caus¬ ing those taking the course to enter the company or regi¬ mental office and actually perform the practical work connected with these duties. In addition, such theoretical work may be given as the instructors deem advisable. 53. A-3. Sanitary .—This course will be arranged and conducted by the senior medical officer present with the command. B. General service training. 54. B-l. Care of arms and accoutrements. —Texts: Infantry Drill Regulations and Small-Arms Firing Manual. Purpose: In order to prevent injury to arms and accoutre¬ ments due to misapplied efforts, carelessness, or neglect, instructions in the care of the rifle, pistol, bayonet, and other equipment should be given recruits immediately after the issue of these articles. Equipment: Company and individual equipment. Method of instruction: The captain or a designated sub¬ altern will assemble the corporals, give them the instruction, and then require the corporals to give the same to their squads under his supervision. The captain by means of rigid inspections will see that this instruction and his orders on the subject are carried out. Corporals should be held responsible at all times for the proper appearance of the men in their squads and for the proper care of the equipment. Steps in training: (1) Description of contents of pack and haversack. Demonstration of how to make up same. Each man should then be required to make up and put on his pack. Faults are then pointed out and corrected. (2) Lecture, with demonstration when called for, covering the following subjects: (a) Nomenclature of parts of rifle (I. D. R., pi. 1) and bayonet (par. 11, Manual of the Bayonet). ( b ) Use of oil and ammonia solution. (c) Cleaning rod, proper method of use (from breech). 54 ENGINEER TRAINING MANUAL—VIII. (d) Oiler and thong case when used, relative value of this and cleaning rod. (e) Caution against using shellac or other preparation on the stock. (/) Necessity for constant care of rifle and bayonet in order that they may prove effective weapons in time of need. Rifle qualification, extra pay. (g) Improvised rods and thongs. Danger of using steel or iron rods. (h) Care of rifle at drill, on the march and in battle. Danger of leaving it on the ground. Failure to function on account of dust, dirt, and mud. (i) Character of fouling of bore. (j) Relative effect of injury to bore near muzzle and breech. (k) How to take rifle apart and put it together. (Per¬ mission necessary to remove all except certain parts.) 55. B-2, physical drill. —Text: Manual of Physical Training. Purpose: The objects of the course in physical training are to impart to its recipients general bodily vigor, smartness, activity, and precision. Equipment: Company and individual equipment. Method of instruction: All should be required to attend the drill. The scope and methods to be followed in this in¬ struction are very completely covered by the Manual of Physical Training and the instructions in it relative to the schedule below will be observed in minutest detail. The drills will be repeated in sequence. If the colonel believes this drill to be given too soon after breakfast, he may inter¬ change this period and that of the Infantry drill period. The instructor should explain which muscles are to be developed by different exercises, so that the drill will be more interesting to the men. It will also help them to deter¬ mine which exercises to go through out of drill hours if they wish to develop a certain set of muscles. Two and four count exercises should be given at first and the more com¬ plicated ones after these have been understood. Pick and shovel work may be substituted for any part of the drill at the discretion of the colonel. Besides hardening ENGINEER TRAINING MANUAL- Yin. 55 the hands and muscles, such exercise may be used to teach the men to dig without lost motion or wasted effort, and to make cuts or fills useful in connection with Engineer training. Steps in training: Drills will be given in the following order. Before going to drill the instructor should consult the manual, if necessary, in order that he may be entirely familiar with the work. In this drill, more than in any other, lack of vigor, precision, and purpose will destroy the object of the exercise. First drill— (1) Marching in quick and double time, flexion marching. (2) Setting-up exercises. (3) Jumping exercises. (4) Trunk and arm exercises. Second drill— (1) Exercises in marching, combined with arm and leg exercises. (2) Setting-up exercises, chiefly trunk exercises. (3) Exercises in coordination. (4) Stretching and breathing exercises. Third drill— (1) Double and quick time and marching exercises. (2) Setting-up exercises, general. (3) Rifle exercises. (4) Jumping exercises. (5) Stretching and breathing exercises. Fourth drill— (1) Running and walking. (2) Setting-up exercises. (3) Jumping trenches and clearing obstacles. (4) Stretching and breathing exercises. Eifth drill— (1) Exercises while marching in quick and double time. (2) Coordination exercises in setting-up drill. (3) Jumping trenches and clearing obstacles. (4) Gymnastic contests. (5) Stretching and breathing exercises. 56 ENGINEER TRAINING MANUAL—VIII. 56. B-3 . Infantry drill. —Texts: Infantry Drill Regulations and Training Infantry (Morrison). Purpose: This drill is given to insure soldierly bearing, discipline, proper conduct of marches, and a knowledge of the principles of deployment and advance under fire. Engi¬ neers go forward with the first wave of the attack and should therefore be as skilled as Infantry in this part of the advance. Equipment: Individual equipment. Method of instruction: The attention of instructors is called to the fact that their lack of zeal and energy will be reflected in lack of precision in the execution of movements. Commands should be given in clear rising tones which de¬ mand attention and response. Drills should not be unduly prolonged and should be varied as much as possible. Signals will be given until troops are entirely familiar with them. The schools of the soldier and of the squad will be given by squad instructors and noncommissioned officers, under the direction of company officers. In order to expedite matters the brighter and more adaptable recruits should be combined, and those who are slower to learn placed in other groups. This preference will excite comment and the back¬ ward men will try harder to do well. As soon as a fair degree of proficiency is attained in these schools, the others will be taken up in succession. Instructors, officers of proper grade. Steps in training: (1) Schools of soldier and squad. Manual of Arms. The company will be divided into sections corresponding to the number of instructors who are available. As soon as the rudiments of the steps, facings, and marching are learned; i. e., men can stay in ranks, they will be given rifles and instructed in the manual of arms. (2) School of the company. As soon as squad movements can be executed with a fair degree of accuracy, this school should be taken up. Its benefits are superior to (1) in that better instructors are available to all and more interest is developed in the larger movements. Extended order should be given a part of the period as soon as the elements of close order are learned. As discipline is more difficult to maintain ENGINEER TRAINING MANUAL—VIII. 57 in this class of drill, it should not be attempted until atten¬ tion and response are assured. (3) School of company. Extended order on varied ground. The advance, use of cover. (4) School of the battalion. This should be attempted as soon as the battalion commander believes the companies capable. Too much time should not be spent in the school of the company, as the details of company drill can be per¬ fected in the school of the battalion. (5) Elementary combat principles by extended order. (6) The regiment. This drill should be undertaken only when the others are fully understood. 57. B-4-a. Interior guard duty .—Texts: Manual of In¬ terior Guard Duty, and Infantry Drill Regulations. Purpose: In addition to providing an efficient interior guard for the regiment, this training will supplement Infantry drill, by increasing the quality of discipline of the troops. Equipment: Company and individual equipment. In case the supply of manuals in the company is insufficient for the need, the company commander should have the parts of it relating to the various grades copied by typewriter or mimeo¬ graph and distributed to the men concerned. Method of instruction: The company wall be divided into three guards, each under a lieutenant acting as officer of the guard, the captain performing the duties of officer of the day. Theoretical instruction and study will be followed by practical application of the principles learned. Each noncommis¬ sioned officer must learn the duties of the grade above him. Steps in training: (1) Division of the company into guards. Distribution of manuals and instructions. Talk by lieu¬ tenants on duties, as laid down in the preceding. General supervision by captain. (2) Posting reliefs. Parallel posts or quadrangles should be staked out on the parade. Each guard will be divided into three reliefs. While one is on post, the other two will devote their time to study and questions under direction of the noncommissioned officers. The lieutenant and captain, by inspecting the reliefs, will see if the orders and duties are 58 ENGINEER TRAINING MANUAL-VIII. being learned. They will pay particular attention to these points: (a) Military bearing of sentinels. ( b ) Proper execution of the Manual of Arms. (c) Application of orders: What to do in case of fire; how to proceed in case of disorder, suspicious persons near post, escaping prisoners, etc.; how to ask for relief. (d) See that sentinels know by name and sight the com¬ manding officer and members of the guard detail. ( e ) Require clear-cut answers to such general questions as may come up in practice. (3) Same as (2) simulating night work, require challeng¬ ing. (4) Simulate some of the conditions in (2) and (3). For example, select certain noncommissioned officers to act as marauders, drunks, etc. Proceed on the hypothesis that certain houses are on fire, etc. Conduct some of this practice at night. (5) Duty over prisoners. Procedure at guard mounting, at the guardhouse, and at work. Establish a certain area for the guardhouse, have formal and informal guard mount¬ ing. Designate two reliefs to act as prisoners and the other to take charge of them. (6) When the captain is satisfied that his company can perform guard duty without damage or loss of property, impairment of discipline, or loss of prisoners committed to it, he will so notify the colonel. 58. B-Jf-b. Small-arms practice. —Texts: Infantry Drill Regulations, Small-Arms Firing Manual, and Bull's-eye Score Book. Purpose: Small-arms training has for its object the development of individuals capable of delivering an instan¬ taneous, accurate, and quick fire on any target with the weapons with which they are armed. It must also develop good fire discipline. Equipment: Individual equipment. Sighting bars, mark¬ ers, and rifle rest can be made by placing a sand bag on a small tripod or by using the bag alone. For prone rests the box given in the manual is best. ENGINEER TRAINING MANUAL— Yin. 59 Method of instruction, general: The selection of the officer to supervise the target instruction of the regiment as a whole will depend upon the experience of the officers avail¬ able, and will be a separate problem for each regiment. The extent of this officer’s personal supervision will depend on his own experience, and the experience of the officers under him. In any case it will be desirable to stimulate as much friendly rivalry as possible between the two battalions, among the companies, and among the squads in each com¬ pany. The best results are obtained when target practice is made an essentially sporting proposition, and success can not be attained unless each man takes a live interest in the matter, and is willing to undergo the necessary training in order to accomplish the desired result. Try to pick out instructors who can keep up this interest. It is desirable to have instructors who have had some experience on the ran e, but remember that the best shots are not always the best instructors. One officer in each company should be given entire charge of the target instruction in the company. For various reasons, the captain will sometimes find it advisable to assign this work to a lieutenant. The captain should personally supervise this work, however, and should require all his lieutenants to take part in the instruction. It will be successful in the same degree as zeal and interest are shown by company officers. Before a good shot can be developed, his muscles must be trained in the mechanism of firing. For this reason, position and aiming drills should be frequently given. They should, however, be short. During the target season, it is suggested that this drill be included in the calisthenics. Method of instruction, rifle: The following method of instruction has been found to be successful in practice. Some modifications may be found desirable in particular cases. Where the captain is mentioned below, it should be understood to refer to a lieutenant if he has been assigned to the instruction. The individual instruction in the company should be given by squads. A squad instructor, either a sergeant or corporal, should be permanently assigned to each squad. 60 ENGINEER TRAINING MANUAL-VIII. The captain should personally instruct the squad instruc¬ tors, going into details, in exactly the same way that he wishes the squad instructors to instruct the individual men. The theoretical instruction should be given entirely by informal lectures or talks. The captain first lectures to the squad instructors, giving practical illustrations wherever possible. The squad instructors later repeat this instruc¬ tion to their squads, being careful to bring out all essential points. The captain should supervise the squad instruction, going from squad to squad; if he keeps his ears open, he will get a few good pointers himself, which he should later pass on to the other squad instructors. If a squad instructor fails to bring out some point, the captain should later call his attention to it. On suitable occasions, the captain may give the entire company a short talk on target practice, its importance, etc. The main part of the theoretical instruction is given by the following 12 lectures, given by the captain to the squad instructors, and by the squad instructors to the men. Each lecture with its accompanying exercises will take about half an hour. But as some instructors are slower than others, three quarters of an hour should be allowed. Sufficient information is given in the Manual for Target Practice and Johnston’s Score Book to enable the captain to prepare the lectures, especially if he has had some experi¬ ence on the range. Steps in training, rifle (subjects for lectures): (1) Impor¬ tance of target practice. Necessity for Engineers. Outline general methods and course of instruction. Practice on range. Extra pay. (2) Use and care of rifle. Illustrate practically. Use of ammonia solution in rifle is not necessary provided bullet is slightly greased with good automobile cup grease before putting cartridge in rifle. (3) Principles of sighting; focus of eye. (4) Positions. Use of sling. Keep loop of sling well up on arm near shoulder. Keep sling tight when shooting. This will be somewhat uncomfortable at first, but will damage no one who is not an invalid. End up the lecture ENGINEER TRAINING MANUAL-VIII. 61 with a few sighting and snapping exercises, standing. Each man should bring his own rifle to the instruction. During all sighting exercises, or other exercises simulating condi¬ tions on the range, the instructor should give his most careful attention to correct position, proper holding of breath, and other details of method, or peculiarities of the individual men. Faults should be pointed out and cor¬ rected, but an instructor will lessen his own value if he scolds a man for mistakes which are due to his ignorance and inexperience (5) Rapid fire. Positions. Illustrate. End up lecture with sighting and snapping exercises, kneeling. (6) Rapid fire. Precautions. Time limit. Illustrate proper method of inserting clip and operating bolt to prevent jams. Caution the men that only practice before going to range will enable them to correctly time their shots in rapid fire. Sighting and snapping exercises, sitting. (7) Zero of rifle. Adjusting sights. Explain carefully the principles of sight setting. Sighting and snapping ex¬ ercise, simulating rapid fire, sitting. (8) Effect of wind. Minor effects of heat, light, etc. Exercise in adjusting sights. In connection with the ques¬ tion of sight setting, probably the best rule for the average man on the range, in setting his sights for any shot, is to correct for one-half the error of the preceding shot. Through¬ out the instruction course, it is considered advisable to require that the complete correction be made each time. End up with sighting and snapping exercises, rapid fire, sitting. (9) Exercises in adjusting sights. Collective and indi¬ vidual instruction, illustrated by practical problems. Sight¬ ing and snapping exercises, rapid fire, sitting. (10) Exercises in adjusting sights. Continue instruction of previous lesson. Sighting and snapping exercises, rapid fire, prone. (11) Service in the pits. Explain the duties of the pit details. Caution to place center of disk over shot hole in marking. Sighting and snapping exercises, rapid fire, prone. 62 ENGINEER TRAINING MANUAL—VIII. (12) Use of score book. All men should be required to use the score book. Johnston’s score book is recommended. Sighting and snapping exercises, rapid fire, prone. The above course is somewhat brief, but it can be made to cover all the essentials of the theory. The men should be encouraged in sighting and snapping exercises at odd mo¬ ments, as before or after drill. For this purpose put up a few miniature targets at convenient places. The practical instruction should follow the same general methods and organization that are used in the theoretical instruction. Throughout this part of the course the in¬ structors should always watch carefully for faults in holding, breathing, etc. The men should fire with deliberation in slow fire. Even in rapid fire sufficient time should be taken to steady the rifle before each shot. The following should be included in the practical in¬ struction : (1) Sighting exercises. Use some of the methods pre¬ scribed in the manual to determine that each man has a practical understanding of the principles of sighting. (2) Triangles. As prescribed in manual. Minimum of three per man. Additional triangles to determine error where triangles are poor. (3) Hollifield dotter. Have each man simulate rifle known distance course. Watch position, etc. (4) Gallery range. Have each man simulate marksman course. Some gallery rifles are not accurate. A good group of shots is as satisfactory as a good score. Watch position, etc. Use sling properly, although improper use will not affect results as much as on the range, where the kick of the rifle is much greater. (5) Range • practice. Instructors should assist men as much as possible in the preliminary practice, watching to see that they use correct methods, and attempting to locate the trouble when the scores are not good. Method of instruction, pistol: Methods of rifle training apply to the pistol with some very self-evident modifications. Steps in training: (1) Nomenclature and care of pistol. (2) Methods of holding and aiming. ENGINEER TRAINING MANUAL-VIII. 63 (3) Practice slow fire. (4) Practice rapid fire (5) Practice quick fire. (6) Record practice. 59. B-4-c. Bayonet combat and trench or close combat .— Texts: Manual of the Bayonet and Engineer Field Manual. Purpose: Due to the nature of the duties which Engineer troops must perform, they will not infrequently be called on to defend themselves or assault with the bayonet or some form of trench weapon. This instruction is to insure success to the soldier in such combats. Equipment: The company is furnished with fencing rifles and bayonets, but if these should not be supplied a pole of the correct length and weight will answer the purpose equally well. The end should be suitably padded and pro¬ tected to prevent injury to the fencers. Masks are pro¬ vided and should be used invariably. Hand grenades, bombs, etc., will be obtained from the supply officer. For instruc¬ tion in throwing them trenches should be prepared and ser¬ vice conditions should be approximated as nearly as possible. Stones, cans, etc., can be advantageously used for drill pur¬ poses in lieu of the actual missiles. Method of instruction: The course of instruction in bayo¬ net fighting teaches the mechanical movements which one must learn to do subconsciously and then endeavors to give the bout some of the aspects which a true combat possesses. A certain amount of strength and agility are necessary to a good bayonet fighter, and too much emphasis can not be laid on nice execution of the foot movements, the various thrusts and lunges. This work requires careful attention and supervision by the instructors. For this reason the squads should be small if efficient instruction is to be obtained. In the following schedule, every effort should be made to introduce competition among the men, squads, and platoons. Bayonet fencing is an exciting sport and instructors should take care not to turn it into a calisthenic drill. As long as its true nature is maintained there will be no trouble in obtaining good results. Lack of progress on the part of the men shows a lack of zeal in the instructors. 64 ENGINEER TRAINING MANUAL—VIII. Steps in training (bayonet): (1) Instruction without rifle, Part I, Bayonet Manual. (2) Instruction with rifle with and without bayonet, Parts II, III, and IV, Bayonet Manual. (3) Fencing by direction of instructor, Parts V and VI, Bayonet Manual. (4) Fencing at will, groups of two, Part VII, Bayonet Manual. (5) Squad and platoon fencing on even and varied ground. Attack and defense of trenches. (6) Use of regulation bayonet. Attack on dummies placed in different positions. The dummies should be placed erect (swung from poles like football dummies), prone on level ground, and prone on uneven ground. The object of this drill is to put life into the movements and to demon¬ strate the necessary force required to cause the bayonet to pierce the object attacked, the difficulty of extracting the bayonet after a touch, and other difficulties encountered in actual combat. Steps in training (bomb and grenade throwing): (1) Physical exercises in throwing at targets on even ground and from trenches or into trenches. (2) Description of grenades, fuzing, effects. Bombs and grenades containing the caps without the charge should be used before service weapons are issued. Attacks on dum¬ mies in trenches. Ordnance pamphlets, pages XXXII and XXXIII (Addenda Engineer Field Manual, 1916). Asphyxiating gas: No authoritative data on this subject is available (Addenda Engineer Field Manual, 1916, pp. XXXV and XXXVI). As soon as data are available, this very important detail of trench warfare should be thoroughly investigated. 60. B~4~d. First aid, hygiene , and litter drill.— Texts: Military Hygiene (Ashburn), and Soldiers’ Handbook. Purpose: The training in these subjects aims to give enough knowledge of the principles of hygiene to enable the soldier to realize the purpose of the various sanitary pre¬ cautions taken, their importance and the necessity for their observance. The first-aid and litter drills should give the ENGINEER TRAINING MANUAL-VIII. 65 participants a thorough understanding of the most approved methods of caring for wounded in so far as such duty falls to line troops. Equipment: Each company is provided with a litter. The first-aid drill packet should be obtained from the surgeon. If these are not available, the issue packet should be used or bandages of the proper size should be obtained from the surgeon. Method of instruction: The course in hygiene should be given first. This should be given by the surgeon or by one of his assistants who is a good lecturer. The course in first aid and litter drills should first be given by the surgeons to the company officers and by them to their organizations. Steps in training: (1) Hygiene— First lecture: Personal hygiene dealing especially with care of feet, size of shoes, clean underwear, care of teeth, etc. Second lecture: Venereal diseases. Venereal prophylaxis, necessity for, and efficacy. Third lecture: Camp diseases and epidemics, means of prevention. ( а ) Water-borne diseases: Description of use of Lister water bag and Darnel filter; necessity for boiling water con¬ taining magnesium or other substances which will combine with and render inert the purifying compound furnished for the Lister bag. The talk should include a description of water which may or may not be drunk with safety. (б) Insect-borne diseases: Fly, mosquito, lice, etc. (c) Contact or human carrier diseases. These lectures should be given to groups of not over 350 men (two companies). Every man in the regiment, includ¬ ing all officers, should be required to attend each lecture. The lectures should avoid technicalities and should be given in such a way as to be understood by those of least educa¬ tion and understanding. The fact that the success of all undertakings will depend on the health of the command must be impressed on the audience. (2) Practical instruction of the company officers in first aid and litter drill by the surgeon and sanitary troops, 104121—17-5 66 ENGINEER TRAINING MANUAL-VIII. (3) Instruction of the companies in these drills by their officers. The Soldiers’ Handbook contains the subject mat¬ ter to be taught in these drills. 61. B-Jf-e. Tent pitching and individual cooking .—Text: Infantry Drill Regulations. Purpose: Upon the completion of this training, the regi¬ ment should be able to pitch all kinds of tents furnished it, in the most efficient and expeditious manner. All members of the command should be able to cook the reserve ration and such parts of the field ration as can be handled in the individual mess kits. Equipment: Company and individual equipment. Ra¬ tions to be drawn by the regimental supply officer. Method of training: Instruction in tent pitching should be given by platoon. As soon as the members of the pla¬ toons have learned their duties the company will be united for purposes of competition under the immediate super¬ vision of the captain. Cooking will be taught by platoons. Number of platoons for both kinds of training is three. Steps in training: (1) Shelter tents: Each lieutenant,after having caused his platoon to take intervals preparatory to pitching tents, will cause one file to step to the front, where the men can be seen by ail in ranks. He will then give the commands for pitching tents and go through the operations one by one, using the file out of ranks for demonstration. When they have a fairly good grasp of the subject, he will begin to keep time on the various squads, always announcing the time and the first squad through. In no case will he , allow a tent with a sagging ridge, or otherwise badly con¬ structed, to stand. After all the platoons are fairly competent, the company will be united. The captain will then keep time on the platoons. Competition is a great stimulus in this kind of work. (2) Similar methods with pyramidal tents. (3) Pitching wall tents. (4) Cooking: The lieutenants assemble their platoons^and give a short talk on the different kinds of rations, where pro- ENGINEER TRAINING MANUAL-VIII. 67 cured, when eaten, etc. The captain assigns the mess ser¬ geant to one platoon and a cook to each of the others. (a) Fires. Materials for making and lighting fires, shelter¬ ing them from wind and rain. This is made the subject of a demonstration by the lieutenants. (b) Reserve ration. How cooked—demonstrated by the cooks. (c) Cooking reserve ration by men. (d) Further demonstration and practice with components of field ration. (e) Cleaning and care of mess kits—talk and demonstra¬ tion by the lieutenants. [Note. —Men should be allowed no luncheon except that of their cooking on these days. Drill grounds should be scrupulously policed.] 62. B-4-f- Company on service of security. —Texts: In¬ fantry Drill Regulations and Field Service Regulations. Purpose: As a general rule, engineers will not be called on to furnish their own security. When this does occur, how¬ ever, they should be skilled in patroling, advanced guard, and outpost duty. Interior guards are dealt with in another section of the Manual. It is to give the necessary skill mentioned above that this training is introduced. Equipment: Company and individual equipment. Method of instruction: Instruction will be by company under company officers until the purpose and mechanism of the formations are understood. The companies will then be combined to form larger units. Steps in training. —(1) Patrolling. The company will be told the essentials of good patrolling, then divided into small patrols and each given a mission. Patrol leaders must un¬ derstand the reasons for the existence of their commands, and have a clear and definite idea of their mission. The cap¬ tains by inspection of the patrols, using one against the other and examination of reports will determine how well the work is being done. (2) Security on the march. (Pars. 596-622, 636-660, I. D. R. Chapter on security, F. S. R.) No march should 68 ENGINEER TRAINING MANUAL-VIII. be begun without assuming some tactical situation. This should be explained to the noncommissioned officers by the captain and they should endeavor to give the men enough detail to keep up their interest in the work. Avoid giving new formations and new principles until those previously given have been assimilated and understood. (3) Security in camp. (Pars. 678-707, I. D. It. Chapter on security, F. S. R.) The captain should bear in mind that the duties of an outpost are to secure the uninterrupted rest of his command and he should make his dispositions accord¬ ingly. While this is practically impossible with a small com¬ mand he should bend every effort toward prevention of sur¬ prise or capture. (4) Company acting as part of a larger body of troops. The duties of the company on the march will be regulated, of course, by higher authority. It therefore becomes the company commander’s duty to apply the principles learned in (1), (2), and (3) to the solution of problems presented to him by his superiors. It is always best to have an enemy represented so that conditions of actual warfare may be more exactly simulated. 63. B-5. Applicatory problems and tests. —-Texts: Infantry Drill Regulations and Service Schools’ Publications. Purpose: This training is to give a few practical applica¬ tions of the principles set forth in B-4-f. Equipment; Company and individual equipment. Method of instruction: The company will first be divided into small groups for the solution of the simpler problems. These will be combined later for the solution of platoon and company problems. The instructor will first explain the problems for the day and by inspection of the parties and their reports complete the instruction. The enemy is to be represented and the troops are to be used against one another whenever practicable. Steps in training: (1) Small patrols, 2 to 8 men. Engi¬ neer reconnaissance. (a) Against railroad: To determine best method of put¬ ting same out of action. Exact location of bridges, cul¬ verts, switches, etc. ENGINEER TRAINING MANUAL-VIII. 69 ( b) Against groups of buildings: Number and location, whether or not they should be occupied and improved for defense. (c) Against canal or water course: Inundation of sur¬ rounding land. Location of locks and dams. (2) Small patrols, 2 to 8 men. Tactical reconnaissance. (a) Defensive position: Pick out and locate. ( b ) Offensive position: Pick out and locate. (c) River crossing: Pick several out with reference to assumed position of the enemy. (d) Mountain pass: Locate line of advance. (e) Occupation of wood: Method of attack to be deter¬ mined. (3) Large patrols, platoon. Same as above in (1) and (2), using larger area. (4) Advance guard: For single company; for larger unit to include regiment. (5) Flank guard: Same as for (4). (6) Rear guard: Same as for (4). (7) Outposts: Small groups, pickets, sentry squads, and cossack posts. (8) Organization of outpost supports and reserve. (9) Method of attack on small town or group of buildings. (10) Same as all of above, giving drills at night. 64. B-6. Ceremonies. —Texts: Infantry Drill Regulations, Army Regulations. Purpose: Ceremonies are of value chiefly in that they give higher commanders an insight into the discipline of the organization. A further purpose is that they allow the men to see what they themselves can do in marching and what other companies can do, and thus promote esprit de corps. Equipment: Individual and company equipment, colors. Method of instruction: The ceremonies should first be tried at drill without music, and when the formations are understood, at the proper time with the band. Steps in training: (1) Battalion parade. (2) Battalion review. (3) Regimental parade. (4) Regimental review. 70 ENGINEER TRAINING MANUAL—VIII. (5) One escort to the color may be substituted for a parade at the discretion of the colonel. 65. B-7. Mounted drill and care of animals for mounted sec¬ tions. —Text: Cavalry Drill Regulations. Purpose: The object of this drill is to make the individual a good military horseman (par. 175, C. D. R. except par. d) and the platoon an exceptionally mobile unit which will be able to execute Engineer works at a distance with the great¬ est dispatch. The platoon should be schooled in combina¬ tion with those from not over three other companies in troop movements, so that when they are combined for Engineer operations the units will be able to operate efficiently and without confusion. Equipment: Company and individual equipment. Method of instruction: The special instructor in charge of mounted work will be selected with reference to his qualifi¬ cations and particularly his interest in such duty. An ex¬ perienced instructor without enthusiasm is not so good as one with less experience but more enthusiasm for the work. In addition to the work mentioned above, the platoon should receive instruction in the pistol attack, dismounted action, and the service of security and information. On being assigned to this work every officer should obtain from the Army Service School Press a copy of the 1917 In¬ struction in Equitation. This contains many valuable sug¬ gestions which will be followed during the preliminary train¬ ing and in the school of the troops. Instructors will study and comply with the provisions of paragraphs 4 and 5, C. D. R. Their attention is also directed to paragraphs 11, 12, 14, 16, 17, 18, 20, 22-31, such parts of paragraphs 34-50 as relate to mounted drill. Every horseman and every horse will, of course, require special treatment, but wide departures from the Equitation Manual and Drill Regulations wili not be countenanced. Sections are to be combined so that they will all receive instruction from the best instructor in the battalion. Instruction at stables: The officer in each platoon should give an informal 10-minute talk before stables each day on ENGINEER TRAINING MANUAL-VIII. 71 one of the subjects given below. He should encourage questions both before and after feeding and grooming but not while these duties are being performed. Whenever any ailment is found among the horses, he should explain the cause, nature, remedy, and methods of preventing same. He should not permit questions on subjects other than those relating to the care and treatment of horses and their equip¬ ment. The talks should be continued until they are mani¬ festly unnecessary. Steps in training: Sequence of talks at stables. (1) Conformation and points of the horse. (2) Rules for the care of the horse (par. 966, C. D. R.) will be posted in stables until understood by all concerned. (3) Necessity for good stable management and careful grooming. (4) Feeding and watering in camp and on the march. (5) Minor ailments, how prevented and cured. Sequence of drills: 1 (1) School of the trooper, mounted, C. D. R. paragraphs 172-320. (Follow schedules in pars. 176-223; 268-300.) Devote a part of every drill period to this school. For the first two periods nothing else should be taught. For the next two, one-half the period should be. devoted to this end and one-half to the school of the squad (2) School of squad. Part II, third and fourth periods and in succeeding ones in so much as the squad movements are incorporated in platoon movements. (3) Platoon and troop drill, Part III. Throughout re¬ maining periods troop drill should be given a part of a period as often as the senior battalion instructor deems advisable. C. General service training schools. 66. C-l.

Steps in training: (1) Components of ration: Both mess sergeants and cooks should be instructed in the components of the garrison, field, and emergency ration and the use of each. (2) Menus: The methods for preparing suitable menus should be studied. These should provide a propeily varied diet and the utilization of the entire ration and requiie as little additional subsistence stores as practicable. The question of the quantity of supplies necessary to furnish meals in accordance with these menus, for a given strength of the company, should also be studied. (3) Meats: Inspection, butchering, curing, storage, and preparation for cooking. (4) Vegetables: Preparation for cooking. (5) Breads, pastry, and deserts: Mixing. (6) Cooking: A course in practical cooking should be taken by the cooks and closely followed by the mess sergeants. This course should aim particularly to teach principles not actually applied in restaurants; to avoid waste; and to secure the proper degree of flavoring, etc. The course should be conducted both with the ordinary field range and with the lightest type cooking equipment which it is probable the company may take into the field. It should also include the construction and operation of field ovens for baking bread. Cooking will be studied in the following order: Meats. Vegetables. Bread, pastry, etc. (7) Construction of field ovens. Brick, masonry, and mud, (8) Kitchen management. This course should be followed by the mess sergeant, and the cooks should be instructed in ENGINEER TRAINING MANUAL-VIII. 73 the necessary operations of it. It should include such matters as instructions for kitchen police, methods for clean¬ ing all kitchen ware and mess gear under field conditions, and above all, proper care, use, and cleaning of dish towels. (9) Accounts and management. Mess sergeants should be taught the proper methods of keeping their accounts and how to determine the funds probably available. In par¬ ticular they must be impressed with the importance of accu¬ racy in keeping accounts, of cooperation in the kitchen per¬ sonnel, and of cooperation with the company commander. They should also be instructed as to their responsibility con¬ cerning the proper cooking and serving of food. 67. C-2. First sergeants’ and clerks’ school. —Texts: Books of record in company office; forms given in Appendix 2 of this Manual. Purpose: This school is intended to minimize the errors in official correspondence, to insure proper and prompt trans¬ mission of orders, proper posting, filing, and keeping of official records, orders, and correspondence, and, in short, to produce efficient office work. Equipment: The required blank forms will be furnished by the regimental supply officer. Manuals, regulations, etc.,, will be brought to class by the students. Method of instruction: Instruction will cover first those sub¬ jects which are common to all offices in the regiment and then proceed to matters handled only by battalion and regiment headquarters. Special stress will be placed on field forms. Steps in training: (1) Lecture on necessity for keeping correspondence, records, etc., up to date and according to regulations.

Test of knowl¬ edge by having students make out all forms and reports given therein. This work should be conducted as follows: Each class period should be a small edition of a complete day’s work. The men should be required to start the day with sick and morning report, and then the day’s corre¬ spondence should be given to the first sergeant and he and his clerks required to handle it. Soldiers will be assumed to be discharged or have charges preferred against them under a variety of hypothetical circumstances. (7) Instruction in keeping regulations and manuals up to date. Interpolating changes and additions. (8) Study in connection with the above, and supplemen¬ tary to it, all paragraphs of Army Regulations, general orders, etc., cited in Appendix 2 of this Manual. 68. C-3. Supply sergeants’ school. —Texts: Army Regula¬ tions; various blank forms given in Appendix 2. Purpose: The school must develop men familiar with accountability and responsibility for, and the source, method of procurement, transfer, and issue of property furnished for the use of the regiment. They should be taught to care for, make minor repairs to, and handle in the most expeditious manner the property in their charge. Equipment: Forms furnished by the regimental supply officer; regulations and manuals brought to class by stu¬ dents. Method of training: The instructor should explain meth¬ ods and forms and then require the students to fill them in. He should pay particular attention to the method of keep¬ ing track of property. He must impress on the students the necessity for keeping an abstract of memorandum re¬ ceipts and property account up to date. He must show that this is necessary, particularly where quick and frequent transfers of property are taking place, as in war time. The supply sergeant should be able to tell the exact loca¬ tion of every article for which he is responsible. ENGINEER TRAINING MANUAL-VIII. 75 In the field his duties will be these of a construction store¬ keeper. Steps in training: (1) Source. Division of property into classes—Engineer, Ordnance, Quartermaster, and Signal. Outline of the class of property furnished by each. (See Appendix 1 for publications giving lists of property.) Ex¬ plain what is to be obtained from regimental supply officer and the various depots and officers from whom he obtains his supplies. (2) Method of procurement. Requisitions, ration and forage returns, informal requests. (3) Accountability and responsibility. Remember that under the new system the regimental supply officer is che only accountable officer in the regiment. All others hold their property from him on memorandum receipt. Explain difference between an invoice and memorandum receipt; be¬ tween nonexpendable and expendable property; how r prop¬ erty can be dropped; relief from accountability and respon¬ sibility. (Inspector, boards of survey, etc.) Outline sys¬ tem of returns, invoices, and receipts in different depart¬ ments. Call attention to the fact that the Quartermaster keeps a running account, whereas the other departments close theirs semiannually. (Appendices 1 and 2.) Explain the system of keeping the soldiers’ individual accounts (Forms, Appendix 2), and what is done when he loses or destroys some of his equipment or damages Government property. (4) Transfer and issue of property. (a) By regimental supply officer. By invoice and receipt. By memorandum receipt. ( b ) By company clerk. On memorandum receipt. (5) Blank forms (Appendix 2).

Explain care of tools and equipment and how to make minor repairs. Particular attention must be paid to field and campaign conditions. 69. C~4- Stable sergeants’and farriers’school. —Tests: Cav¬ alry Drill Regulations; The Army Horse in Accident and Disease. In addition to the above Government publications, Carter’s Horses, Saddles, and Bridles, and Marshall’s Hip- pology are valuable. Purpose: This school is to develop men fitted to cope with the regular routine and problems which arise in the care and treatment of horses and mules. Equipment: Company equipment. Method of instruction: A short talk on the scope of the day’s work will be followed by practical demonstrations. The stable sergeant should be able to perform every duty devolving on a member of the mounted section better than any man in it. The instructor should, therefore, lay par¬ ticular stress on the actual doing of the work. After the talk the class will be divided into groups of two or three men and assigned to tasks which will be performed by the individuals in rotation. The instruction will be given at the company stables in rotation, so that the students will become familiar with the cleanliness and management of stables belonging to other organizations and with a large number of horses. Steps in training: (1) Stable management. Arrangement of animals, feed, and equipment; administration and disci¬ pline; guard and orderlies; forage returns and daily reports. (2) Feeding, watering, and bedding: How to select good oats and grain; best kinds of hay, how distinguished; when and how much to feed; corn as a substitiue for oats; when to water; change of bedding, when allowed (particular atten¬ tion to march conditions). (3) Grooming and general care of animals: Use of comb, cloth, and brush, horse covers; what to do when overheated, etc.; rules to be observed while grooming.

C-5. Packers’ school. —Texts: Engineer Field Manual and Addenda, - 1916; Manual of Pack Transportation; The Army Horse in Accident and Disease. Purpose: This instruction is to enable the pack train to deliver its load at the point needed, at the proper time and in good condition. Equipment: Company equipment. Note that eight mules and aparejos are provided and only five Engineer packs. The three extra mules are for carrying grain or unusual sup¬ plies and equipment. 78 ENGINEER TRAINING MANUAL—VIII. The McClellan saddle can be used for packing light loads and with a little care it will give very efficient service. Special pack devices will be found in Chapter VIII, Manual of Pack Transportation. Methods of instruction: During steps 1 to 8 the class will first be given a short talk on the subject of the day’s work and then be assigned to tasks and animals in groups of two men. During the remainder of the course the instruction will be by groups, each composed of a company pack section. The lieutenants in command of the mounted sections should be present whenever possible. Steps in training: (1) Conformation, grooming, use of comb, cloth, and'brush. (2) Simpler ailments of mules. Symptoms and first aid for more serious troubles; when to call farrier and veterinary. (3) Picket lines and picketing. How erected, drainage and police. (4) Aparejos, bridles, and halters. Nomenclature, descrip¬ tion, how fitted; saddling up; cause of bunches and saddle sores; how avoided. (5) Ropes and Engineer packs. Coiling, splicing, and lash¬ ings. Loading Engineer packs. (6) Grain loads: throwing double hitch. (7) Miscellaneous loads: picks, shovels, bars, rations, etc. (8) Special devices. McClellan saddle, saw buck saddle. (9) Organization of train. Duties of packers on march and in camp. (10) Review of (6), (7), and (8). (11) Short marches. These are especially valuable, as the packers’ mistakes become very apparent, slipshod lashings give way, and the effects of poor and unequal loads become evident. (12) Care, repair, and construction of saddles, etc. Par¬ ticular attention should be paid to proper methods of stuffing aparejos. 71. C-6. School for buglers and orderlies .— Visual signal¬ ing. —Texts: Infantry Drill Regulations; Cavalry Drill Reg¬ ulations; Uniform Regulations. ENGINEER TRAINING MANUAL-VIII. 79 1 Purpose: This school must turn out musicians able to sound the service and special calls, and to send and receive messages efficiently by the means furnished the company and provided for in the Infantry Drill Regulations. Equipment: Company equipment. Method of instruction: Instruction is given by the sergeant bugler under the supervision of an officer specially qualified in these subjects. All buglers in the regiment and two- alternates from each company will attend the school. Part of the drill period will be devoted to music and part to signaling. Instruction in work as orderly will be obtained by informal talks on military courtesy, soldierly bearing, insignia of rank, and procedure to gain admittance to various offices. Steps in training: (1) Wigwag. Alphabet. (2) Wigwag. Sending and receiving; numbers and special signals. (3) Semaphore. Alphabet. (4) Semaphore. Sending and receiving; numbers and special signals. The following should be given at the same time as the signal training: (1) Instruction in method of blowing a trumpet, breathing and position of lips. (2) Service calls. (C. D. R., par. 994; C. D. R., par. 996.) Alarm calls. (C. D. R., par. 993.) (3) Drill and field calls C. D. R., paragraphs 996, 995. Musicians should be required to study the signal codes outside of drill hours. 72. C-7. Horseshoers’ and saddlers’ schools. —Text: The Army Horseshoer. Purpose: This school should provide enough men to keep the animals of the regiment properly shod and the horse equipment in good repair. Equipment: Battalion and company blacksmith and horse shoeing outfits and the company saddler’s outfit. Method of instruction: The class should be divided into two groups, horseshoers in one and saddlers in the other. •80 ENGINEER TRAINING MANUAL-VIII. Instructors will first give a talk on the day’s work and then require each man to perform the various operations required. Steps in training: (1) Horseshoers’ instruction. (a) Tools and their uses. (Chs. I and II, Army Horse- shoer.) The fire. ( b ) Working and shaping iron. A lead bar can be used to advantage in this work to show the forms. Its use will save the time ordinarily taken in heating. (c) Anatomy and physiology of horses’ feet. (Ch. IV, Army Horseshoer). (d) Normal shoeing. ( e ) Gaits. Shoeing to confirm, or alter same; faults in gaits; shoeing to correct same; making special shoes for gaits. ( f ) Diseases of the foot: Cause, symptoms, treatment; pathological shoeing, making pathological shoes. (2) Saddlers’ instruction. (a) Tools and their uses; leather, nature, how to tell good from bad. ( b ) Splitting and cutting, leather punches. (c) Use of awl, sewing. (d) Making simpler parts of equipment, stirrup leathers, etc.; riveting. (e) Fitting leather over tree; working leather with cloth, wood, and steel. D. General engineer training schools. 73. Individual instruction in the various schools (D) is commenced early in the course and continued until it is about over. All of the men attend these schools. In the first assignment to classes it would be web to pick the men for subjects analogous to their civil life vocation, which would enable them to become military specialists in the shortest possible time. When proficiency has been attained, transfers should be made within each “ group ” of schools, and if possible each man should be put through at least two courses, but attainment of practical proficiency shoiud not be sacrificed to this end. The map reproduction school may be continued indefinitely. ENGINEER TRAINING MANUAL-VIII. 81 All the companies should be drawn upon for the necessary equipment for :hcse schools, and the first day’s work should consist in preparing equipment for use and in obtaining the necessary materials. One member of each class should be detailed as property man to assist the instructor in caring for the equipment and tools. It is suggested that a storage tent, a hospital tent, or other shelter be provided for each school, for the storage of tools and equipment, and for such work as can be conducted indoors. These tents should not be on the company streets but should be within the chain of sentinels. The schools should be grouped sufficiently close together to enable easy supervision by the major in charge of the work. 74. D-l. Riggers’ school. —Text: Engineer Field Manual. Purpose: This school will provide expert riggers and lashers for the different companies. Equipment: Company equipment. Method of instruction: The instructor will see that each man is provided with a piece of three-quarter inch rope of sufficient length and the necessary number of spars. He will give demonstrations of the proper way to tie the knots and then walk among the men giving aid and making suggestions. About three or four knots or lashings will be given per day and those already covered will be reviewed until the men are expert in making them. All these things should be noticed until the men become so proficient as to do the work by force of habit and instinct. The uses of the various knots and lashings should be demonstrated by the erection of derricks, gins, shears, pile drivers, and lashed trestle bents. The lash¬ ings should be applied in all sizes. Application of knots and round bights should be demonstrated by the handling of rafts, scows, and ponton boats in swift current. A good exercise in speed, typical of methods which may be adapted to other subjects, is to give three men a bit of rope and have them start to walk away with it; then require another man to pick up the moving rope, snub it, and make it fast to a post or tree, the three attempting to prevent him from doing so by pulling on the rope. The power of holdfast should be demon- 104121—17 6 82 ENGINEER TRAINING MANUAL-VIII. strated by pulling also. The increased pull through the use of power should be demonstrated. Steps in training: (1) Knots, page 164, to include “Crown on wall,” page 171, Engineer Field Manual. (2) Splices, pages 170 and 171, Engineer Field Manual. (3) Lashings, pages 171 and 172, Engineer Field Manual. (4) Blocks and tackle, pages 172 to 176, Engineer Field Manual. 75. D-2. Ponton school. —Texts: Engineer Field Manual. Ponton Manual. Purpose: This school is to develop expert lashers and men who are adept in loading and unloading ponton material, in arranging and assembling it, and in launching boats. Equipment: Ponton equipment will not always be avail¬ able. If assigned to the regiment the division may be given to one company or be kept by the supply officer. In any case, the instructor should have such parts of it as are needed in this training transferred to him on memorandum receipt. Method of instruction: The schedule given under “Steps in training” is for complete ponton training. This school, aiming to give instruction in detail, should spend most time on steps 1 and 2a. The other steps belong more properly to company training, but should be undertaken if the progress warrants it. When the details report to the instructor he should com¬ bine them to act as a ponton company. As groups become proficient in their duties, they should be interchanged. This should be continued until all are familiar with all parts of the drill. Steps in training: (1) Work on shore: (a) Loading and unloading equipment. For this purpose the details from three companies will be assigned to ponton wagons, those from two companies to chess wagons, and that from the remaining company to a trestle wagon. ( b ) (i) Erection of trestles, two companies. (ii) Balk lashings, two companies. (iii) Side-rail lashings, two companies. (2) Work afloat: (a) The class should be re-formed and divided according ENGINEER TRAINING MANUAL-VIII. 83 to the table on page 65 of the manual. The instructor should then build a bridge by successive pontons. He should be on the alert to assist and direct those groups whose lack of progress is holding up the work. He should cause these men to repeat their tasks until they can be accomplished with celerity. When all have become familiar with their duties the bridge should be rebuilt. The details should then be changed and the work repeated. (b) Construction of bridge by parts. (c) Construction of bridge by rafts. Construction and operation of draw. (d) If site is available the method by conversion should be attempted. 76. D-3. Rowing school. —Purpose: The single object of this school is to develop men suitable for the anchor details in ponton bridge work. They should be schooled until thoroughly proficient in handling oars and paddles, in mak¬ ing up anchor line, and in mooring boats under the most severe current conditions. Equipment: Upon reporting for duty the instructor should divide the class into groups of six and assign each to a ponton in charge of a special instructor. Method of instruction: He will pursue the instruction exactly as it is laid down in the school of the pontonier in the manual. This can not be improved on. Steps in training: When the men become adept in han¬ dling the oar, instruction in the school of the boat will be given. When the boat can be adeptly handled, instruction in mooring it in different positions will be given. A current may be simulated by towing the boat. When this has been mastered instruction will be given as follows: (1) Nomenclature and use of calking materials and tools will be taught. (2) A boat with open seams should be given to the students and placed in repair by them, each being required to do a part of the work. 77. D~4- Bridge carpentry school. —Texts: Engineer Field Manual. Trautwine, Kidder, or other standard handbooks. 84 ENGINEER TRAINING MANUAL-VIII. Purpose: This school is intended to develop men who are skilled in the carpentry work connected with construction of trestle bridges of all kinds and heavy timberwork con¬ nected with construction. They should all be drilled in the use of the ax, adz, and crosscut saw, should learn to use drift bolts, and should practice in laying out joints and in the methods of handling square and round timbers. Equipment: Company equipment. If on a Government reservation, round timber can probably be obtained by felling trees. If on leased land, timber of all kinds will have to be obtained through the regimental supply officer. Method of instruction: Carpenter squads should consist of not more than one noncommissioned officer and four privates. Work should begin with scrap timber. Full- size timber should be cut if available. The time allotted to this work is not sufficient to permit framing on one-half or one-fourth scale as a preliminary to full scale work. If, howei^er, due to lack of supply, timber can not be obtained, half-size work may be done in lieu of the full size. Steps in training: (1) Sharpening and putting in order the tools; sharpening and setting saws, grinding axes, adzes, etc.; proper applications of carborundum and grindstones. (2) Use of ax and adze: Felling and dressing of timber; cutting to a line with ax and adze, green and seasoned timber. (3) Use of saw: (two-man). Felling of trees; sawing to a line; sawing on the diagonal (one-man), green and seasoned timber. (4) Joints: Square and bevel; miterbox, scope, how made, use. Squares, try and angle. (5) Use of augers, brace and bit, drift bolts. Use of hatchet, hand ax and hammer, nailing. (6) Pick out site and take measurements for a four-post trestle bridge. Construct same. Each group should be required to construct at least one trestle and part of floor system. In most cases and particularly with beginners it will be found advantageous to spike all heavy joints with a few nails before driving the drift pins. A much better joint will be secured in all hasty work and in most cases when the work is allowed to proceed at its ordinary rate. The bridge ENGINEER TRAINING MANUAL—VIII. 85 is built primarily for carpenter work and this should be borne in mind. If sufficient timber is available the pile driver may be constructed at the same time and one or two pile bents put in the bridge. Timbers should not be large enough to require special rigging to handle them. (7) Explanation of. different parts of the bridge con¬ structed; necessity for side rails, bridging, sway bracing, mud sill, batter posts; short talk on strength of timber, best way to utilize material. (8) Construction of field pile driver. (Engineer Field Manual.) Drive two or three small piles. (9) Construct derrick from material used in making pile driver. (10) Construct and explain use of a round and a square timber crib. 78. D-5. Trench layout school .—Texts: Engineer Field Manual and addenda. Purpose: The importance of this branch of engineer train¬ ing can not be emphasized too much. Its purpose is to de¬ velop noncommissioned officers w r ho will be able not only to indicate by unmistakable means the location of new lines of trenches but be able to organize captured trenches, shell craters, ditches, and houses in the shortest time and in such a way as to provide the best cover and defensive position against counter attacks. In addition to being able to indicate the necessary work the noncommissioned officers should learn how to make cor¬ rect estimates of the labor, material, and time necessary to complete the section which is assigned to them or which falls to their lot in the advance. They should be taught the various elements in a line of defense or offense and should be able to pick out the more important elements of such a line. They should understand the schemes for enlargement and improvement of a line taken up so that their work will not be rendered useless by subse¬ quent developments. Work should be conducted in all kinds of weather and some training must be given at night in addition to that prescribed in the schedule. 86 ENGINEER TRAINING MANUAL-VIII. Equipment: Stakes, tape, and hand axes should be brought by the details from their companies. Method of instruction: The work for the day should be made the subject of a short talk by the instructor. This should be followed by the actual location of the work on the ground. Better progress will be made if the entire work is laid out and constructed in miniature in a sand box. The men can there see the ensemble and get a better idea of the relation of the different parts to each other. Work should be conducted strictly in accordance with the 1916 and 1917 addenda to the Engineer Field Manual. Steps in training: (1) Explanation of what is considered the best organization of trenches in the present war. This should include: Types of firing, cover, approach and com¬ municating trenches; types of shelters; listening, observa¬ tion, commanders’, and machine-gun posts; false works, dummy trenches, emplacements, etc.; traverses, attached and detached (island); cooking places and latrines. (2) Organization of supporting point for a battalion. (See plates in addenda.) (а) Fire trenches, first. (б) Approach trenches. (c) Fire trenches, second. ( d) Approach trench, reserve to second. (e) Communicating trenches to adjoining supports. (J) Special trenches and posts. (i) Machine gun. (ii) Company commanders’. (iii) Battalion commander’s. (iv) Listening or observing post. (v) Kitchen. (vi) Latrine. (vii) Indication of location of dugouts used for shelters. (3) Organization of shell crater, of farm, of cut. (4) Organization of captured trenches for delivering fire in opposite direction. (Establish elements of line in same order as given in (2).) ENGINEER TRAINING MANUAL-VIII. 87 (5) Artillery emplacements: (а) Light mountain howitzer. (6) Three-inch field gun. (c) Heavier mobile pieces. (d) Antiaircraft gun. (e) Aerial torpedo guns. 79. D-6. Revetment school. —Texts: Engineer Field Manual and addenda. Purpose: This school will develop selected men in the methods used in making ordinary revetments and their ap¬ plication to trenches. Equipment: Picks, shovels, saws, machetes, gabion knives, axes, wire, wire cutters, and nails from companies. If revetment material can not be found in sites it must be requisitioned from the regimental supply officer. Method of instruction: Company details will be kept dis¬ tinct. Work will be explained by the instructor and then executed by everyone in each group. The groups will be assigned to one of the tasks below and will be interchanged when they become familiar with the work. Work should be executed in all kinds of soil available. Some instruction must be given in trenches containing more or less water. Trenches dug during the morning drill will be utilized as far as practicable. In this way the men digging in the trenches will be able to observe the result of the revetment work as well. Steps in training: (1) Talk on necessity for and applica¬ tion of revetments to trench walls and other military works. (2) Sandbag revetment and parapet. (3) Gabion revetment and parapet. (4) Same with fascines. (5) Same with hurdles. (б) Combination of (3), (4), and (5). (7) Wire revetments. (8) Timber revetments. (9) Plank revetments. (10) Revetments made, from miscellaneous material’likely to be present: Cane, barrels, corrugated and sheet iron. 88 ENGINEER TRAINING MANUAL-VIII. (11) Concrete revetment. (12) Sod revetment. (This method is slow and not satis¬ factory and little time should be spent on it.) Sod should be cut in strips, rolled up, spread out in the proper place, and cut to proper length. The squares are harder to cut and not so satisfactory. 80. D-7, cover and accessories school. —Texts: Engineer Field Manual and addenda, 1916 and 1917. Purpose: This school is to develop foremen able to handle all situations which may arise in the construction of trenches and cover. They should understand the nomenclature of all special devices and how to make them. They should be able to organize and direct working parties and to prepare bills of material fot different tasks. Equipment: Picks, shovels, saws, squares, axes, nails, wire, wire cutters, sandbags from company; sheet iron, tim¬ ber, and other articles not pertaining to companies from regimental supply officer. Method of instruction: Small-scale work can be used to great advantage in this work, especially if material is scarce. Before assigning a task the instructor will explain typical organizations suitable for doing similar work in large quan¬ tity. The sand box offers a good means for showing proper coordination of work. Instructors must emphasize the necessity for careful organization, supervision, and inspec¬ tion of work. It is only in this way that fast and efficient work can be done. Only short sections of work will be attempted until all types are thoroughly understood. The relation of these to the general scheme of advance or defense will be indicated by their connection with D-5 and D-6. The details of con¬ struction must be clearly brought out and understood. The kind of timber, size, etc., necessary for the different types of construction must be clearly indicated and the men given practice in making out bills of material for different projects. The work in this school should be conducted in connection with D-5 and D-6 as far as practicable in order that each may get the benefit of the other’s work. The layout men will ENGINEER TRAINING MANUAL-VIII. 89 have the advantage of seeing their work actually accom¬ plished, and this school will not have to waste time in prepara¬ tion. This school must be able to recognize and execute the work pertaining to all contemporary trench devices. Steps in training: (1) Elements of fire trenches. (a) Head cover. (i) Loop holes: Sandbag, steel, wood and earth; crenelated. (ii) Screens: Bomb and aerial torpedo screens. ( b ) Overhead cover: Against shrapnel; against shell of small caliber. (2) Cover: Bomb proof for fire trenches, including com¬ mander’s post. (3) Cover: Bomb-proof quarters, kitchens, latrines. (4) Emplacements: Machine guns, light mortars, torpedo guns. (5) Observation stations and listening posts. (6) Alarms: Whistle and bell. (7) Lighting: Electric, flares, star bombs, etc. (8) Disposal of water. (a) Drains. ( b ) Sumps. 81. D-S. Obstacle school. —Texts: Engineer Field Manual and addenda. Purpose: This school should produce men skilled in the construction and placing of the various military obstacles. Equipment: The necessary material should be obtained from the regimental supply officer; tools from the companies. Method of instruction: The construction of obstacles under fire requires careful preparation, detailed organization, and men entirely familiar with this organization and their indi¬ vidual duties. Instruction should therefore be given as fol¬ lows: First, individual training in making the obstacles; second, group work on level ground in the day; third, group work at night. Steps in training: (1) Wire entanglements (stake type): Complete and detailed instructions for constructing these are given in the 1917 addenda to the Engineer Field Manual. 90 ENGINEER TRAINING MANUAL-VIII. Smooth wire should be used until the details have been mastered, when barbed wire should be substituted. (2) Sawbuck and tripod types of entanglement: 1916 and 1917 addenda. (3) Brun spirals (short section). (4) Abatis and slashings (Field Manual). This is little used and little time should be spent on it. (5) Easily moved obstacles: Chevaux de frise: , (a) Wood. ( b ) Wood and wire. (c) Iron or steel angles. 82. D-9. Miners’ and sappers’ school. —Texts: Engineer Field Manual and addenda. Purpose: This school is to develop proficiency in driving galleries and sinking shafts; the use of frames and sheeting and cases; mine ventilation, and the charging and firing of mines. Instruction will also be given in sapping. Equipment: Tools and explosives from companies; tim¬ ber, supplies, and mechanical digging devices from regi¬ mental supply officer. Method of instruction: Much time can be saved by merely constructing the timberwork for the mines above ground. The work can be illustrated with a sand box. Men should have experience in the actual work in all steps. Mechanical methods of digging have met with success abroad and some work should be done with a light jack-hammer drill if this can be obtained. The class should be divided into two groups, one being assigned to sapping and the other to mining. As this work is exceptionally slow, only so much of it should be attempted as will clearly illustrate the principle involved to all the students. Steps in training: Sapping. Parties are given in the En¬ gineer Field Manual and 1917 addenda. (1) Drive single sap. Change direction three times. (2) Double sap. (3) Use of sandbags for shield at head of sap. (4) Use of loose earth with log or some variety of long- handled sweep to advance the earth shield. ENGINEER TRAINING MANUAL—VIII. 91 Mining: (1) Drive shaft with cases. (2) Galleries: % (a) One great gallery with change of slope. ( b ) Two half galleries. (c) Two branches with charges. (3) Place and explode four charges of diffeient size in the galleries. Detonate them one at a time, examine effect on other galleries, repair the latter, and proceed as before. Although it will probably not be necessary to introduce artificial ventilation in the shaft and galleries, this should be done for purposes of instruction. (4) Same as above (1), (2), and (3), using frames and sheeting. 83. D-10. Demolition school. —Texts: Engineer Field Man¬ ual and addenda. Instructions for the use of the United States Cavalry Demolition Equipment, 1917. Purpose: The object of this training is to familiarize those assigned to the work with the various military explo¬ sives, their effects, and the methods of handling them. Equipment: Company equipment, demolition outfit, such other explosives (dynamite, guncotton, melinite, and blast¬ ing powder from regimental supply officer) as colonel may direct. Method of instruction: Except when a lecture is specified, the day’s work will begin with a short talk to the class on the results which are expected that day and how they are to be obtained. This should be followed by practical demon¬ stration and each man should be required to go through every operation until he can do it with celerity. For the practical work the class should be divided into groups, each consisting of the detail from one company. As other explosives in addition to those forming a part of the regular equipment (trinitrotoluol) may have to be used, a few exercises with the more common ones on the market and in use by foreign nations are given. Steps in training: (1) Lecture regarding field of applica¬ tion and importance of military demolitions. Give a short history of the part they have played in military operations 92 ENGINEER TRAINING MANUAL—VIII. together with the tacticial failures and successes which have resulted from their use.

Purpose: The primary object of this school is to train the men in making an engineer and a tactical reconnaissance. A secondary object is to develop facility in the simpler methods of sketching and military surveying. Equipment: Field message books obtained from the regi¬ mental supply officer. Company reconnaissance equipment. Method of instruction: The course should begin with the study of the nature and object of reconnaissance work. This should be followed by practice in the use of various instru¬ ments and in the making of maps. After this, problems should be worked out in both tactical and engineer recon¬ naissances involving necessity for making maps and sketches in some cases, and in other cases requiring only preparation of verbal or written reports. Steps in training: (1) Talk on requirements of a good engineer reconnaissance. Nature and extent of work to be done, whether trench, bridge, or road work; personnel and material required; time necessary; whether work is to be done under fire, under cover, or back of lines; exact location of work; route to be followed by personnel and material in reaching work. Requirements of tactical reconnaissance: Location, compo¬ sition, strength, and activities of enemies’ troops, routes to 94 ENGINEER TRAINING MANUAL-VIII. be followed in reaching them, and location of any of our own troops in their neighborhood. The talk should also include the means for obtaining the information contained in the above. Whole class. (2) Sketching (in pairs): (a) Making pace or stride scale. Application of scale.

General engineer training .—At the conclusion of the school course, the bridge sections, the fortification sections, and the mounted sections of each battalion should be consolidated for applicatory work (E-l, 2, and 3). This should consist for each battalion in a problem in field forti¬ fication and a problem in fixed bridges to be conducted simultaneously, and for the mounted section participation in both and special work in demolitions and engineer reconnaissance. The problems should involve and demon¬ strate the application of the detailed work learned in the schools. On the completion of the work by section, each company should conduct a problem in floating bridge work, and in general pioneer work involving the repair of roads, simple bridge construction, and the siting and consolidation of a simple defensive line (E-4). In this work men in the bridge section should have an opportunity to work as laborers on other work and men in the fortification section as laborers on bridge work (chess and balk carrying, handling, sorting, and piling timber and the like). The mounted section should have appropriate work. ENGINEER TRAINING MANUAL— Yin. 99 General exercises in military engineering involving simple pioneer work, tactical, topographical, and engineer recon¬ naissance and demolitions, will be continued to the end of the course in connection with practice marches and field exercises (G). 87. F. Engineer specialists. —Toward the end of the course duly qualified men should be designated as specialists in each company, as provided for in paragraph 40 of Part I. These men will be made familiar with the tools carried which pertain to the work and thereafter may be used on their respective specialties (Course III). 88. G. Practice marches. —These are introduced early in the course and continued at intervals, culminating with a six-day march of at least 80 miles near the end of the course. The object at first is to accustom the men to marching in route order with light loads. Later individual cooking and midday bivouacs are introduced and the loads are increased. This is followed by a short march with full equipment involving a stop in shelter tent camp for the night and a night problem. As the men become accustomed to the work the marches are lengthened and tactical and engi¬ neering problems are made a prominent feature. Orders issued by all commanders in the course of the solution of any problem should conform to the principles prescribed in Field Service Regulations for field orders. 89. H. Instructors’ school. —The purpose of this school is to develop the necessary number of instructors for carrying on the course. No detailed instruction will be given further than that. This work should anticipate the ground to be covered in the actual work of the instructors during the fol¬ lowing days. It may be necessary to divide the classes into sections to correspond with the various kinds of work to be done. As soon as practicable, this course should be sus¬ pended and the further work of preparation for instructing should be covered by the officers’ and noncommissioned officers’ schools. 90. I. Officers’ school. —The elementary course described in Part III of the Engineer Training Manual should first be followed to completion. After this the intermediate course 100 ENGINEER TRAINING MANUAL-VIII. may be taken up or the work carried out on special lines as the colonel may think necessary. 91. J. Noncommissioned officers’ school .—The course of instruction should be governed by the experience of the non¬ commissioned officers and the needs of their work in connec¬ tion with the general course of training. The following sub¬ jects are suggested: (1) Duties and responsibilities of the noncommissioned officers. (2) Customs of the service, military courtesy, etc. (3) Infantry Drill Regulations. (4) Field Engineering. Appendices to this manual will be used as textbooks. Throughout the course particular stress should be laid on matters of immediate application and the general work of training and duties which it is expected that the noncom¬ missioned officers may be called upon to perform on taking the field. It is recommended that classes be not larger than the quota of noncommissioned officers for a single company. It is left to the discretion of the colonel as to whether this instruction be carried on entirely by the company command¬ ers, each for his own noncommissioned officers in all sub¬ jects, or whether a special instructor should be assigned to each subject and the classes rotate from one subject to another. The former method is recommended. In general, it should be possible to simplify the work by covering each day in a general way the ground covered recently in the officers’ school, in so fai as this is applicable to the non¬ commissioned officers. 92. K . Lectures. —First, lectures should be on the general subject of the duties, responsibilities, and privileges of a soldier and the customs of the service. After this, lectures should be used to demonstrate the purpose and application of practical training to come within the next few days, and criticize the results of work done. Lectures on special ob¬ jects will be introduced as soon as desirable. Some sug¬ gestive topics are given in paragraph 25, Chapter III. CHAPTER V. COURSE III. 93. As stated heretofore, Course III is designed to train thoroughly the individuals, both officers and men, of an Engineer regiment in their duties in war. This course pre¬ supposes the completion of Course II or an equal degree of efficiency; namely, first, all members of the organization have been instructed in their elementary duties as soldiers, so that they can be handled as a military unit; second, individuals in each company have been instructed in the elements of the specialties falling to the share of Engineer troops; third, the occupants of such positions as first sergeant, mess sergeant, company clerk, cooks, stable sergeant, horseshoer, etc., are sufficiently proficient to perform their duties in a satisfactory manner. Engineer regiments raised particularly for railroad work, highway construction, and other special service, will be recruited from men having knowledge of these particular specialties in civil life and they will require a minimum of military instruction and no more technical training than is necessary to insure their cohesion and frictionless operation as a military organization. Such special troops should be ready to undertake the duties for which they are intended upon completion of Courses I and II and no provision is made for them in Course III. 94. The course of instruction in each subject will conform to that laid down for the same subject in Course II; but a greater time being available, each detail will be gone into more thoroughly, and, in order to insure the requisite team work, instruction should be by company, under the imme¬ diate supervision of the company commander, in everything except trade school courses, which should be under the regi¬ mental topographical officer. The physical facility and strength necessary for a rapid completion of Engineer work in the field can be attained only 101 102 ENGINEER TRAINING MANUAL—Yin. by accustoming the men to actually performing the physical labor of similar tasks. A considerable amount of marching and of manual labor must, therefore, be included in this course. §5. The daily schedule of work will conform in general to that prescribed in Course II, with the following changes and omissions: B-3 and B-5 will be by company, then by battalion, and then by regiment. B-7. Mounted sections of each battalion should be con¬ solidated for training under the senior detachment com¬ mander, and all the mounted sections of a regiment may with advantage often be consolidated for training as two troops under one of the majors. C. Omit. D. Individual Engineer training. The part of the com¬ pany not engaged in receiving special technical instruction will be exercised in the general duties coming under this head, the method of solving definite problems in military engineer¬ ing being adopted, and special attention being paid to the planning and organization of their part of each job by officers and noncommissioned officers. The mounted section should receive instruction in all the items except D-2 and D-9. F will now include the instruction of Engineer specialists in trade-school courses in the following subjects: 1 Instrumental surveying. Topographical sketching and reconnaissance. Drafting, topographical and mechanical. Lithography and map reproduction. Photography. Blasting and military demolitions. Carpentry. Blacksmithing. Plumbing and pipe fitting. 1 Suitable trade-school courses in carpentry, masonry construction, and black- smithing, are included in Appendices 4, 5, and 6, respectively. A guide for courses in (a) surveying, sketching, and reconnaissance, (6) lithography, and (c) photography, is contained in separate pamphlets published by the Engineer Department. ENGINEER TRAINING MANUAL-VIII. 103 Masonry construction. Rigging. Packing. Saddlery and repairs to harness. Where the necessary apparatus can be obtained addi¬ tional courses for electricians, enginemen, and firemen should be organized. Men should be detailed for a period of one month or two months as assistants to those in regular administrative posi¬ tions in which a certain amount of special knowledge is requi¬ site (such as mess sergeants, cooks, company clerks, horse- shoers, farriers, etc.), in order to insure the presence in the company of company substitutes for these positions. H. Omit. 96. The total time allotted for Course III should be about eight months. It is considered that this time can best be divided into five successive stages: First stage: Two months. Individual instruction in gen¬ eral service in Engineer training. Second stage: Two months. Collective instruction in Engineer training by section and company. Third stage: Two months. Battalion and regimental prob¬ lems in duties of Engineer troops. Fourth stage: One month. Problems in general service and duties of Engineer troops combined with other troops. Fifth stage: One month. Problems and tests covering the entire course, and additional rifle practice. 97. Typical daily program .—(Based on daily schedule in Course II; modifications in camp routine of police, fatigue, retreat, etc., to be made as necessary.) First stage: First period: Physical drill, mounted drill, of¬ ficers’ school. Second period: Infantry drill and mounted drill. Third and fourth periods: B-4, general infantry instruc¬ tion. Fifth and sixth periods: D, individual engineer training, and F, engineer specialists’ schools. 104 ENGINEER TRAINING MANUAL-VIII. Practice march one day a week, increasing in severity from week to week, and involving the making and breaking of camp, individual cooking, and simple problems in security and combat. Battalion parades twice each week; noncommissioned of¬ ficers’ schools, lectures, athletics, and inspections on Satur¬ days. Second stage: First period: Physical drill, mounted drill, officers’ school. Second period: Infantry drill and mounted drill. Third and fourth periods: B-5, problems in Infantry train¬ ing, all branches, and F. Fifth and sixth periods: E-l, E-2, E-3, E-4, engineer problems by section and company. Committee of officers to work up battalion and regimental engineer problems for application during third stage. Practice marches, ceremonies, and athletics as during first stage. Third stage: Four days a week: Engineer problems re¬ quiring the entire day: (1) Passage of rivers under various conditions; (2) selection of defensive lines and construction of important elements thereof. One day a week: First period, physical drill; second period, infantry drill; remainder of day, practice march. Saturday: Review and inspection; lectures, officers’ and noncommissioned officers’ schools, including solution of ele¬ mentary map problems and terrain exercises. Fourth stage: Field exercises and maneuvers, including combat and practical military engineering. Fifth stage: Tests and field problems designed by the regimental commander to ascertain the degree of training of individuals, companies, and battalions, followed by conferences and critiques necessary to insure correction of any errors noticed. Note.—I t wilJ be found advisable to form the entire company under arms at the first period, stacking arms if necessary, and to proceed from one kind of instruction to another without dismissing the company; making details, taking arms, drawing equipment, etc., as may be necessary. ■ pj‘ ; ; eS I te- ■ m I .
