In my last I informed you that we had captured the enemy’s fleet on this lake. I have now the honour to give you the most important particulars of the action. On the morning of the 10th instant, at sunrise, they were discovered from Put-In-Bay, when I lay at anchor with the squadron under my command. We got under weigh, the wind light at south-west, and stood for them. At 10 A.M. the wind hauled to south-east and brought us to windward; formed the line and bore up. At 15 minutes before 12, the enemy commenced firing; at 5 minutes before 12, the action commenced on our part. Finding their fire very destructive owing to their long guns, and its being mostly directed at the _Lawrence_, I made sail, and directed the other vessels to follow, for the purpose of closing with the enemy. Every brace and bowline being soon shot away, she became unmanageable, notwithstanding the great exertions of the sailing master. In this situation, she sustained the action upwards of two hours within canister distance, until every gun was rendered useless, and the greater part of her crew either killed or wounded. Finding she could no longer annoy the enemy, I left her in charge of Lieutenant Yarnall, who, I was convinced, from the bravery already displayed by him, would do what would comport with the honour of the flag. At half past two, the wind springing up, Captain Elliot was enabled to bring his vessel, the _Niagara_, gallantly into close action. I immediately went on board of her, when he anticipated my wish by volunteering to bring the schooner which had been kept astern by the lightness of the wind, into close action. It was with unspeakable pain that I saw, soon after I got on board the _Niagara_, the flag of the _Lawrence_ come down, although I was perfectly sensible that she had been defended to the last, and that to have continued to make a show of resistance would have been a wanton sacrifice of the remains of her brave crew. But the enemy was not able to take possession of her, and circumstances soon permitted her flag again to be hoisted. At 45 minutes past 2, the signal was made for “close action.” The _Niagara_ being very little injured, I determined to pass through the enemy’s line, bore up and passed ahead of their two ships and a brig, giving a raking fire to them from the starboard guns, and to a large schooner and sloop, from the larboard side, at half pistol shot distance. The smaller vessels at this time having got within grape and canister distance, under the direction of Captain Elliot, and keeping up a well-directed fire, the two ships, a brig, and a schooner surrendered, a schooner and sloop making a vain attempt to escape.
