PREYOST, Augustine, British soldier, born in Generic, Switzerland, about 1725; died in Bernett, England, 5 May, 1786. His father was an officer in the English army. The son also entered the army, became a lieutenant-colonel in March, 1761, colonel, 29 August, 1777, and major-general, 27 February, 1779. He served as captain of the 60th regiment or Royal Americans under Wolfe at Quebec, captured the fort at Sunbury, Georgia, in December, 1778, and defeated General John Ashe at Brier creek in March, 1779, but was foiled in an attempt to cap-lure Charleston in May, 1779. In October, 1779, he successfully defended Savannah against the Americans. General Prevost's widow married Aaron Burr.--His son, Sir George, bart., British soldier, born in New York, 19 May, 1767; died in London, England, 5 January, 1816, entered the army in his youth, served with credit at St. Vincent, where he was severely wounded, and was also at Dominica and St. Lucia. He was created a baronet, 6 December, 1805, and appointed major-general in January of the same year, and lieutenant-genera, 1 in June, 1811. Soon after his return from the West Indies he was appointed lieutenant-governor of Portsmouth, with the command of the troops in that district. In 1808 he became lieutenant-governor of Nova Scotia, , and in the autumn of that year he proceeded with a division of troops from Halifax to the West Indies, and was second in command at the capture of Martinique. He afterward returned to his government in Nova Scotia, and in June, 1811, he succeeded Sir James Craig as governor-in-chief and commander of the forces in all British North America. During the war of 1812 he rendered important services in the defence of Canada against the armies of the United States. His attempt to penetrate into the state of New York was rendered abortive by his engagement with the Americans under General Macomb at Plattsburg, 11 September, 1814, which forced him to retreat into Canada. He soon afterward returned to Eng-brad, and demanded an investigation of charges that had been made against him for the disaster at Plattsburg. He died before this was completed, but the result vindicated his character.
