A TRUE ACCOUNT Of the Entire Defeat of the Rebels in IRELAND; Contained in a Letter from the Lords Justices of that Kingdom, to Their Majesty's Privy Council of SCOTLAND.  
Dated the 15th Current.  
AFter the Taking of Athlone, the Rebels marched to Billynaslow, and thence about three miles further, to a place called Aghrim in Connaught.  
Their Majesty's Army marched from Athlone, in pursuit of the Enemy, and pitched their Camp very near the place, from whence the Rebels had removed a little before.  
The Enemy's Army consisting of about 8000 Horse and Dragoons, and of no less than 20000 Foot, besides Rapparies, had posted themselves very advantageously, having Bogs very near round them; Their Majesty's present Horse, Foot and Dragoons, making about 20000, began the Fight betwixt five and six a Clock upon Sunday the 12th. in the Evening; The Action lasted very sharply for about two hours; then the Enemy began to run, and Their Majesty's Troops had the pursuit of them for about four miles, and would have made the Slaughter much greater than it is, if the Night had not overtaken them. The present Account making the Enemy's loss about 6000, and of Their Majesties, not one thousand.  
The Enemy's General St. Ruth had mightily bestirred himself all that Morning to animat the better sort to this Engagement, and sent the Priests about to do the like to the common Soldiers, to whom they also gave Absolution; And it's said, the Irish were never known to fight so well, as in this Battle.  
On the Irish side, the Lord Galway, Colonel Barker, and several other Officers of Quality are killed; and Major-General Hamilton, Major-General Dorington, Lord Bedlow, Colonel Bourk, Colonel Gourdon, O'neill, Colonel Butler, are taken Prisoners, and a great many more; And of their Majesty's side, not a General-Officer killed, except Major-General Hossaple, and the Prince of Hess, Lord George Hamilton, Lord Lord Cutts, Colonel Earl, and lieutenant-colonel Brudwell wounded.  
It is not certain whether St. Ruth be killed or not; some say he is, but all his Equippage is taken, as also all the Enemy's Baggage and Cannon.
