On the 10th. Instant, I Embarked the Army, and proceeded with the Same, across Lake Ontario into this River, Where, on the 16th. in the Evening, off Oswegatchie the Advanced Guard descried One of the Enemy's Vessells but it being Soon after duskish, Nothing could be Effected that Night, tho' we tryed as much as possible to Attack her: At Day break, on the 17th. Our Row Galleys Engaged her, & by Seven in the morning She Struck: Her Name was the Ottawawa, mounting ten, twelve pounders, and one hundred men Officers Included, besides Monsr. de La Broqueri, Who Commanded her: in the Engagement we had only one Man killed, & another wounded; And the Enemy thirteen of both.

The Army Which the preceding Night had Encamped on the Pointe du Baril, then moved down to Oswegatchie, a very good Indian Settlement with a Blockhouse Fort but Abandoned; the Enemy being posted on an Island, between four & five Miles further down the River, Where they were reported to be very Strongly fortified; both Shores were reconnoitrd during the night, and early the next morning, And the Engineers having reported to me the Situation of the Coasts & Islands nearest the Fort; immediately on the return of the Engineers on the 18th. a part of the Army passed down on each Coast, and after Some Opposition by a Smart Cannonading, the Fort was Compleatly invested, so that none of its Garrison could make its Escape: the four following days were employed in raising my Batteries, Which being finished on the morning of the 23d. in Concert with our Shipping, I began to fire on the Fort, which lasted till Yesterday afternoon; When the French beat a Parley, desiring to know What terms Should be granted them: My Answer was, that the Garrison Should be Prisoners of War; that everything in and depending on the Fort, Should be delivered in the present State; and that I gave them only ten minutes to Accept of, or dissent from these proposals; and they Accordingly Yielded to these Conditions, and I have the Satisfaction to Inform You, that His Majesty's Troops are now in possession of Fort Levis.

Our loss upon this Occasion has been very inconsiderable; that of the Enemy (Whose Garrison Consisted of about three hundred men) about twelve killed and Forty wounded; Mor. Pouchot the Same Gentleman that was last Year taken at Niagara Commanded them.
