GREGORY, Francis Hoyt, naval officer, born in Norwalk, Connecticut, 9 October, 1789; died in Brooklyn, New York, 4 October, 1866. He was in the merchant service in 1807-'9, but became a midshipman in the navy in the latter year. Soon afterward, while serving on the " Vesuvius," and in charge of one of her barges near the Balize, he surprised and captured an English slaver. He was made acting master in 1811, and, while in command of gunboat No. 162, captured a schooner fitting for piratical purposes, disabled and drove away a privateer of greatly superior force, that had been annoying our commerce, and took a Spanish pirate of fourteen guns. He was with Commander Chauncey in all his actions on Lake Ontario, and on 28 June was made lieutenant. In August, 1814, he was taken prisoner and sent to England, where he remained eighteen months. He soon afterward joined one of the frigates cruising against the Algerines, without coming home. In 1821-'3, while in command of the schooner " Grampus," he was active in suppressing piracy on the coasts of Cuba and Mexico, capturing near St. Croix the notorious pirate brig "Pandrita," a vessel far superior to his own in armament and number of men. He was promoted to commander, 28 April, 1828, and to captain, 18 January 1838, and in 1844 commanded the " Raritan " in the blockade of the Mexican coast. His last sea-service was in command of the African squadron in 1849-'52. In July, 1861, he was ordered to superintend the construction of all vessels of war built outside of navy yards, and was engaged in this duty when he died. He was made rear admiral on the retired list, 16 July, 1862.
