A TRUE ACCOUNT OF A LETTER SENT FROM VIENNA August the 23d 1683.  
Declaring the rasing the SIEGE and the Total Overthrow of all the Turkish Army, sent in a Letter from an Eminent English Officer under the Duke of Lorraine, to his Father at White-Hall.  
Honoured Sir,  
AS I am in duty bound to give you Account of my being, as you are the Person from whom I derive it, so I acknowledge myself obliged (next after God, from whose infinite Mercies I do from the bottom of my Heart confess to receive my preservation and well-being) to let you, and my Friends in England understand, as well as of myself, the preservation of a great part of Christendom, from the fury, rage and threatening Ruin, of that implacable and universal Enemy the Turk, who under the Command of the Grand Visier, with a very powerful Army, consisting of near an Hundred and Fifty Thousand men, had a very considerable time Besieged the Imperial City of Vienna; for the relief of which the Emperor had confederated all the Friends and Allies he could in all the adjacent Territories, among which indeed I must say the chiefest was th● King of Poland, whose Conduct and Valour had been sufficiently proved against the Turks, by the several considerable overthrows he hath given them, in Defence of that small Kingdom of Poland, and together with him the Dukes of Bavaria, Saxany, and others of the Princes; of the Empire had joined as they were able to bring up their Forces so that in effect, with the Duke of Lorraine, who Commanded as General all the Imperial standing Forces, they had compacted a pretty considerable Body with which it was advised they might, with the blessing of God, relieve this miserably distressed City. And thus we marched on to try what could be done, but the King of Poland desired First, that he might be a little acquainted with the posture of the Enemy, and to that purpose drew out a considerable party of Horse, and marched on till he came within view of their Leaguer, the Army, especially of Horse, following after with all diligence and Expedition, so that although the Turk, had by his Scout and Spies Intelligence, that there was a powerful Army approaching him, yet he drew leisurely out of his Trenches, not dreading, any great Opposition, especially because he was informed of a strong body of the Bours of the Country, who had gathered to an Head not far from him, Now indeed these poor people having been so long oppressed, and driven from their Habitations by the Turks, ever since they came before Vienna, hearing of the Conjunction of so many good Christian Princes, drawing towards Vienna to relieve it, thought it was now time, not to hid themselves any longer in Holes, and therefore addressing themselves to some old Commanders, who were in an equal condition with themselves, they marched on a little too hastily towards the Enemy, who supposing these the greatest Force coming upon him, sent presently a party to dissolve them, which fell with such Violence upon these poor Men, but half armed, and at the First worsted them, and as is supposed destroyed above 1500 on the place; but just at the same Instant the King of Poland assisted by the Emperor himself and the others, with a full Body of resolute Horse, fell violently upon the Turks Army, who by this time had clearly left their Trenches, and fell upon them with that Conduct, valour and resolution, especially upon the Janissaries, that they were soon disordered, and in a short time became a Prey to the Sword, by which means the Turks main Strength and reliance was quite disa●●ed, and all the rest, who were very numerous, being now bravely assaulted on all hands, (for by this time the Bours, who had before suffered, some little discomfeiture, by the conduct and advice of their Leaders had rallyed and made considerable Opposition) submitted to a General defeat. Tho I mention only the conduct of that Heroic King of Poland, whose Honour can never be enough applauded, yet his Imperial Majesty was in person an Actor in this memorable Battle, as also several Princes of the Empire, whose Catalogue would swell my Letter to an unpleasing length. It is not computed to be a less Number of the Turks slain than 90 or 100000, amongst which is the Grand Visier himself, and so many of the Janissaries, that 'tis believed there will hardly escape Twenty of them to carry the News to Constantinople, to comfort the Grand Signior, the pursuit is so violently Prosecuted, and all the passages so warily Guarded. I cannot descend at present to any further particulars, taking advantage of this ●●ssenger, whose haste is such that I cannot more nicely inform my sel● being in a great Hurry, as most are at present here, but within few days you shall have a further Satisfaction from,  
Honoured Sir, Your most obedient Son W. B.   

POSTSCRIPT.  
I Have been so intent in relating the Proceed of the Armies, that I had quite omitted the condition in which we found Vienna, who th● sufficiently courageous, yet was in very great distress. The last Storm the enemy made upon them was forced on with such Violence, that the account the people of the City gave of it, seems, in their own words very proper as they render it, that they came upon them like Mountains of Men, as they appeared, more than Armies, for the Turk forced his men on so fast, that they run over one another and those that were slain or beaten down, were but Footsteps and degrees of advantage, to mount the successive Troop to that height, that they could in a manner overlook the City-Walls, and in that manner came pouring on with such a desperation, it was very hard to withstand them. Yet by the Blessing of God, and the weak endeavours of the besieged, they were repelled with a very great loss to the Turks, and 'tis thought near 5000 of the Besieged. Which caused the Governor to send to the General, that he could not possibly withstand such another Assault, which Intelligence hastened our Army to the relief of it, as you have in this L●●ter.
