In the month of August, 1839, there appeared in the newspapers a shocking story--that a schooner, going coastwise from Havana to Neuvitas, in the island of Cuba, early in July, with about twenty white passengers, and a large number of slaves, had been seized by the slaves in the night time, and the passengers and crew all murdered except two, who made their escape to land in an open boat. About the 20th of the same month, a strange craft was seen repeatedly on our coast, which was believed to be the captured Spanish coaster, in the possession of the negroes. She was spoken by several pilot-boats and other vessels, and partially supplied with water, of which she was very much in want. It was also said, that the blacks appeared to have a great deal of money. The customhouse department and the officers of the navy were instantly roused to go in pursuit of the "pirates," as the unknown possessors of the schooner were spontaneously called. The United States steamer Fulton, and several revenue cutters were despatched, and notice given to the collectors at the various seaports. On the 10th of August, the "mysterious schooner" was near the shore at Culloden Point, on the east end of Long Island, where a part of the crew came on shore for water and fresh provisions, for which they paid with undiscriminating profuseness. Here they were met by Captain Green and another gentleman, who stated that they had in their possession a large box filled with gold. Shortly after, on the 26th, the vessel was espied by Captain Gedney, U. S. N., in command of the brig Washington, employed on the coast survey, who despatched an officer to board her. The officer found a large number of negroes, and two Spaniards, Pedro Montez and Jose Ruiz, one of whom immediately announced himself as the owner of the negroes, and claimed his protection. The schooner was thereupon taken possession of by Captain Gedney. The leader of the blacks was pointed out by the Spaniards, and his name given as Joseph Cinque. He was a native of Africa, and one of the finest specimens of his race ever seen in this country. As soon as he saw that the vessel was in the hands of others, and all hope of his taking himself and countrymen back to their home land at an end, he leaped overboard with the agility of an antelope. The small boat was immediately sent after him, and for two hours did the sailors strive to capture him before they succeeded. Cinque swam and dived like an otter, first upon his back, then upon his breast, sometimes his head out of water, and sometimes his heels out. His countrymen on board the captured schooner seemed much amused at the chase, for they knew Cinque well, and felt proud of the untamableness of his nature. After baffling them for a time, he swam towards the vessel, was taken on board, and secured with the rest of the blacks, and they were taken into New London, Connecticut.
