At 3 PM could plainly see that she was a ship on the starboard tack, under easy sail, close on a wind; at half past 3 PM made her out to be a frigate; continued the chase until we were within about three miles, when I ordered the light sails taken in, the courses hauled up, and the ship cleared for action. At this time the chase had backed his main top-sail, waiting for us to come down. As soon as the CONSTITUTION was ready for action, I bore down with an intention to bring him to close action immediately; but on our coming within gun-shot she gave us a broadside and filled away, and were, giving us a broadside on the other tack, but without effect; her shot falling short. She continued wearing and manoeuvreing for about three quarters of an hour, to get a raking position, but finding she could not, she bore up, and run under top-sails and gib, with the wind on the quarter. Immediately made sail to bring the ship up with her, and 5 minutes before 6 PM being along side within half pistol shot, we commenced a heavy fire from all our guns, double shotted with round and grape, and so well directed were they, and so warmly kept up, that in 15 minutes his mizen-mast went by the board, and his main-yard in the slings, and the hull, rigging and sails very much torn to pieces. The fire was kept up with equal warmth for 15 minutes longer, when his main-mast and fore-mast went, taking with them every spar, excepting the bowsprit; on seeing this we ceased firing, so that in 30 minutes after we got fairly along side the enemy she surrendered, and had not a spar standing, and her hull below and above water so shattered, that a few more broadsides must have carried her down.
After informing you that so fine a ship as the GUERRIERE, commanded by an able and experienced officer, had been totally dismasted, and otherwise cut to pieces, so as to make her not worth towing into port, in the short space of 30 minutes, you can have no doubt of the gallantry and good conduct of the officers and ship's company I have the honour to command. It only remains, therefore, for me to assure you, that they all fought with great bravery; and it gives me great pleasure to say, that from the smallest boy in the ship to the oldest seaman, not a look of fear was seen. They all went into action, giving three cheers, and requesting to be laid close along side the enemy.
Enclosed I have the honour to send you a list of killed and wounded on board the CONSTITUTION, and a report of the damages she has sustained; also, a list of the killed and wounded on board the enemy, with his quarter bill, &c.
