Saturday, 22d.--Both vessels under way standing to the eastward, they ran the Exertion aground on a bar, but after throwing overboard most of her deck load of shooks, she floated off; a pilot was sent to her, and she was run into a narrow creek between two keys, where they moored her head and stern along side of the mangrove trees, set down her yards and topmasts, and covered her mast heads and shrouds with bushes to prevent her being seen by vessels which might pass that way. I was then suffered to go on board my own vessel, and found her in a very filthy condition; sails torn, rigging cut to pieces, and every thing in the cabin in waste and confusion. The swarms of moschetoes and sand-flies made it impossible to get any sleep or rest. The pirate's large boat was armed and manned under Bolidar, and sent off with letters to a merchant (as they called him) by the name of Dominico, residing in a town called Principe, on the main island of Cuba. I was told by one of them, who could speak English, that Principe was a very large and populous town, situated at the head of St. Maria, which was about twenty miles northeast from where we lay, and the Keys lying around us were called Cotton Keys.--The captain pressed into his service Francis de Suze, one of my crew, saying that he was one of his countrymen. Francis was very reluctant in going, and said to me, with tears in his eyes, "I shall do nothing but what I am obliged to do, and will not aid in the least to hurt you or the vessel; I am very sorry to leave you." He was immediately put on duty and Thomas Goodall sent back to the Exertion. Sunday, 23d.--Early this morning a large number of the pirates came on board of the Exertion, threw out the long boat, broke open the hatches, and took out considerable of the cargo, in search of rum, gin, &c., still telling me "I had some and they would find it," uttering the most awful profaneness. In the afternoon their boat returned with a perough, having on board the captain, his first lieutenant and seven men of a patriot or piratical vessel that was chased ashore at Cape Cruz by a Spanish armed brig. These seven men made their escape in said boat, and after four days, found our pirates and joined them; the remainder of the crew being killed or taken prisoners.
