This day about twelve our army came up with the rebels, about a mile above Lord President's house, in a muir called Drumrossie. They began the engagement first, by firing from a battery of six guns they had erected upon their right; but our cannon played so hott upon them, that they were obliged soon to fly, by which means we gote possession of their artillery, and so drove them before us for three miles of way. The cavalry gave them closs chase to the town of Inverness: {520} upon which the French ambassador (who is not well) sent out an officer, and a drum with him, offering to surrender at discretion; to which the duke made answer, that the French officers should be allowed to go about on their parole, and nothing taken from them. Brigadier Stapleton is among them, and God knows how many more officers; for we have not gote home to count them yet. Its thought the rebels have between four and five hundred killed, and as many taken prisoners already: many more we expect this night, parties having been sent out after them. Lord Kilmarnock I saw prisoner, and Major Stewart, with many more. Secretary Murray is very bad: a party is just now sent for him, intelligence being brought where he is. I don't think we have lost thirty men, and not above five officers killed, amongst which are Lord Robert Ker, Captain Grosset: the rest their names I have forgote. We are now in full possession of this place. Some say the Pretender was in the battle, and wounded; but others say he was not. Such of them as are left are gone to Fort Augustus. The duke, God be praised, is in good health, and all the generalls. His Royal Highness behaved as if he had been inspired, riding up and down giveing orders himself. I am, Gentlemen, Your most obedt. servant, DAVID BRUCE. After writing y^e above, y^e lists of y^e killed and wounded are as follows, so far as is yet known:-- We have of y^e prisoners 700 Killed and wounded on y^e field 1800 Of y^e duke's army:-- Killed, wounded, and amissing 220 * * * * * Gentlemen, I hope you'l pardon y^e confusedness of y^e foregoing line, as I have been in y^e utmost confusion since I came here. 'Tis said, but not quite certain, y^t y^e following rebells are killed, viz.:--Lochiel, Capuch (Keppach), Lord Nairn, Lord Lewis Drummond, D. of Perth, Glengarry, &c. The French have all surrendered prisoners of war. DAVID BRUCE. Addressed to The Governors of The Town of Aberdeen. X. Y. Z. * * * * * OLIVER ST. JOHN.
