Sir Robert Thomas Wilson, an English general, born in London in 1777, died there, May 9, 1849. He was the son of Benjamin Wilson, a painter and writer on electricity, and was educated at Westminster and Winchester. In 1793 he went to Flanders as a volunteer, and in 1794 obtained a commission in the 15th dragoons. He served in Ireland during the rebellion of 1798, and subsequently in Holland, Brazil, and at the Cape of Good Hope. In 1808 he raised the Lusitanian legion in Portugal, and afterward commanded a Spanish brigade under Wellington, and was in the battle of Talavera. From 1812 to 1814 he served as British military commissioner at the headquarters of the Russian and of the allied armies. For his open disapproval of the course pursued toward Queen Caroline, he was dismissed from the army. From 1818 to 1831 he was a member of parliament. After the death of George IV. he was restored to his rank in the army, in 1841 became a general, and from 1842 was governor and commander-in-chief of Gibraltar. He translated Regnier's "Campaign in 1801 in the East and in Egypt," and wrote "History of the British Expedition to Egypt" (1802). He also published "An Inquiry into the Present State of the Military Force of Britain " (1804); " Character and Composition of the Russian Army, and a Sketch of the Campaigns in Poland, 1806-7" (1810); and, " A Sketch of the Military and Political Power of Russia" (1817). His posthumous journals have been edited by his nephew the Rev. Herbert Randolph (5 vols. 8vo, 1860-'63).
