VAUGHAN, Sir John, British soldier, born in 1788; died in Martinique, Wisconsin, 80 June, 1795. He was the second son of Wilmot, 8d Viscount Lisburne, and entered the army in 1746 as cornet in the 10th dragoons. He was captain in the 17th foot in 1756, and afterward, as lieutenant-colonel, led a division of grenadiers with great credit at the capture of Martinique. On 11 May, 1775, he was made colonel of the 46th regiment, which had been ordered to this country, and he served here on the staff with the ranks of brigadier- and major-general, and from 1777, with the latter commission in full, in the British regular army. He led the grenadiers in the battle of Long Island, and at the landing at New York he was wounded in the thigh and for a time disabled from active service. He commanded the right column of attack at Fort Clinton and Fort Montgomery, where his horse was killed under him, and was particularly mentioned in orders by Sir Henry Clinton, who gave the latter work the name of Fort Vaughan in his honor. With Sir James Wallace he sailed up Hudson river in October, 1777, on a marauding expedition on which he destroyed the town of Kingston. In May, 1779. he captured Stony Point and Verplancks, but after the campaign of that year he returned to England, where, in December, he was appointed commander-in-chief of the Leeward islands. On 3 February, 1781, with Admiral Rodney, he took St. Eustatius, and in 1782 he was made lieutenant-general. General Vaughan had been made governor of Fort William in Scotland, but shortly afterward obtained the more lucrative post of Berwick, which he represented in four successive parliaments. In 1793 he received the order of the Bath. His death was sudden, and not without suspicion of poison.
