On the 22 ins^t at 4 o’clk P.M. I set sail from the north end Lake George with 20 sail of Boats three of which were armed, Viz one small sloop mounting 3 guns, and 2 British Gun Boats having on Board the whole about 420 Men officers included with a Determined resolution to attack Diamond Island which lies within 5 miles Fort George at the break of Day the next Morning, but a very heavy storm coming on prevented--I arrived Sabbath Day point abt midnight where I tarried all night, during which time I [sic] small Boat in the fleet taken the Day before coming from Fort George, conducted by one Ferry lately a sutler in our army, I put Ferry on his Parole, but in the night he found Means to escape with his Boat, and informed the Enemy of our approach, on the 23d I advanced as far as 12 Mile Island, the Wind continuing too high for an attack I suspended it untill the Morning of the 24^{th} at 9 oclock at which Time I advanced with the 3 armed Boats in front and the other Boats, I ordered to wing to the Right and left of Island to attempt a landing if practicable, and to support the Gun Boats in case they should need assistance, I was induced to make this experiment to find the strength of the Island as also to carry it if practicable--the enemy gave me the first fire which I returned in good earnest, and advanced as nigh as I thought prudent, I soon found that the enemy had been advertised of our approach and well prepared for our reception having a great number of cannon well mounted with good Breast Works, I however approached within a small Distance giving the Enemy as hot a fire as in my Power, untill the sloop was hulled between wind and Water and obliged to toe her off and one of the boats so damaged as I was obliged to quit her in the action. I had two men killed two Mortally wounded and several others wounded in such Manner as I was obliged to leave them under the Care of the Inhabitants, who I had taken Prisoners giving them a sufficient reward for their services. I Run my Boats up a Bay a considerable distance and burnt them with all the Baggage that was not portable--The Enemy have on Diamond Island as near as could be collected are about three hundred, and about 40 at Fort George with orders if they are attacked to retreat to the Island--Gen^l Borgoine has about 4 Weeks Provision with his army and no more, he is determined to cut his Road through to Albany at all events, for this I have the last authority, still I think him under a small mistake--Most of the Horses and Cattle taken at Ty and thereabouts were left in the Woods. Gen^l Warner has put out a party in quest of them. I am Dear S^r wishing you and the Main Army great Success your most ob^t hum^l Ser^t JNO BROWN.” Gen^l Lincoln
