John Manley, an American naval commander, born at Torbay, Devonshire, Eng., in 1734, died in Boston, Feb. 12, 1793. He settled at Marblehead, Mass., and was master of a merchantman. At the outbreak of the revolutionary war he had command of the armed schooner'Lee, with which he cruised along the coast of Massachusetts bay, making captures of great value to the American army then investing Boston. Among these was an ordnance brig laden with heavy guns, mortars, and intrenching tools. He was commissioned as a captain by congress Aug. 22, 1776; and on June 1, 1777. his ship, the Hancock, 32 guns, in company with the Boston, 24 guns, Capt. Hector McNeil, encountered the British frigate Rainbow, 44 guns. While Manley was preparing for action. McNeil deserted him; and knowing the disparity in strength, Manley tried to escape, but was chased and captured. After a rigorous confinement in Halifax, he was exchanged, and in 1782 was put in command of the Hague frigate, which, after lying in a perilous po-ition on a sand bank off Guadeloupe for three days, exposed to the fire of four British ships of the line, contrived to effect her escape. This exploit closed the regular maritime operations of the United States during the revolutionary war.

Capt. Manley was subsequently tried by a court martial for the loss of the Hancock, but was honorably acquitted, while .McNeil was dismissed from the service.
