We had left the Delaware on the 13th. The 16th had a heavy gale, in which we lost our jib-boom and two men. Half-past 11, on the night of the 17th, in the latitude of 37 degrees north, and longitude 65 degrees west, we saw several sail; two of them appeared very large. We stood from them for some time, then shortened sail, and steered the remainder of the night the course we had perceived them on. At daylight, on Sunday the 18th, we saw them ahead, gave chase, and soon discovered them to be a convoy of six sail, under the protection of a sloop-of-war, four of them large ships, mounting from 16 to 18 guns. At 30 minutes past 11, A.M., we engaged the sloop-of-war, having first received her fire at the distance of fifty or sixty yards, which space we (p. 162) gradually lessened until we laid her on board, after a well supported fire of 43 minutes; and although so near, while loading the last broadside, that our rammers were shoved against the side of the enemy, our men exhibited the same alacrity which they had done during the whole of the action. They immediately surrendered upon our gaining their forecastle, so that no loss was sustained on either side after boarding. Our main-topmast was shot away between four and five minutes from the commencement of the firing, and falling, together with the main-topsail yard, across the larboard fore and fore-topsail braces, rendered our head-yards unmanageable the remainder of the action. At eight minutes the gaff and main-topgallant-mast came down, and at twenty minutes from the beginning of the action, every brace and most of the rigging was shot away. A few minutes after separating from the Frolic, both her masts fell upon deck, the main-mast going close by the deck, and the fore-mast twelve or fifteen feet above it. The courage and exertions of the officers and crew fully answered my expectations and wishes. Lieutenant Biddle's active conduct contributed much to our success by the exact attention paid to every department during the engagement, and the animating example he afforded the crew by his intrepidity. Lieutenants Rodgers, Booth, and Mr. Rapp shewed, by the incessant fire from their divisions, that they were not to be surpassed in resolution or skill. Mr. Knight and every other officer acted with a courage and promptitude highly honourable, and, I trust, have given assurance that they may be relied on whenever their services may be required.
