Artemis took another sip and then went on, and they listened intently, the Braithwaites’ chests swelling when they heard that their father had done the honorable thing. Ordering a change of tack, he picked up the survivors, who were wet and fearful and shivering in the wind. Among them was Annisquam’s first mate, and he told the crew of Main Chance that Captain Robinson’s ship had been bearing northward through the blow on her lower main topsail, which was lost when the wind piped up unexpectedly to eighty knots or better. Crewmen were ordered aloft to clap on new canvas, and that had no sooner been done when the wind gusted some more and blew out the new sail, and then there was nothing for it but to run with the storm on bare poles. Robinson thought he was clear of the Tortugas Reefs, but he wasn’t, and the ship cracked headfirst into the uppermost tip of a long reef shaped like a crescent moon. Annisquam drew twenty feet and she ran hard aground in two fathoms of water and was bilged. With her stern to seas most monstrous, Artemis said, she was rocking up and down with such violence that Robinson feared she would break in two and so ordered most of his crew and all the passengers to man the lifeboats and pull for Fort Jefferson while he remained aboard with the ship’s carpenter and a handful of men.
