Overview
General Thomas Carleton (c. 1735 – 2 February 1817) was an Irish-born British Army officer who was promoted to colonel during the American Revolutionary War after relieving the siege of Quebec in 1776. After the war, he was appointed as Lieutenant-Governor of New Brunswick, and supervised the resettlement of Loyalists from the United States in the province. He held this position until his death, although he was absent in England for the last fourteen years of his tenure, refusing orders to return in a dispute about seniority.
Early life and education
Born in Strabane, County Tyrone, in Ulster, Ireland, to Christoper Carleton and his wife Catherine Ball, he was the younger brother of The 1st Baron Dorchester. As part of a military family, Thomas joined the British Army at a young age.
Military career
In 1753, he was an ensign in the 20th Regiment of Foot and saw action with his regiment during the Seven Years' War. After the conclusion of the Seven Years' War, Thomas Carleton served as an observer during the Russo-Turkish War of 1768–1774.
In 1776 during the American Revolutionary War, as a lieutenant colonel, he arrived in Quebec City with forces to relieve his brother, Sir Guy Carleton, the Governor General of Canada, who was besieged in the city by Continental Army troops. With the death of Lt. Col. Patrick Gordon on July 25, 1776, Col. Carleton was promoted to command the 29th Regiment of Foot. In 1777, Thomas Carleton's nephew Christopher Carleton joined the 29th regiment as a major and served under his uncle's command for the rest of the war. Col. Thomas Carleton did not get along well with his new commander, Frederick Haldimand, who replaced Guy Carleton in 1778 as Governor General of Canada. He refused when in 1782 Haldimand demanded that he resign his position as quartermaster general before his planned departure for New York, where his brother Guy had replaced the disgraced Henry Clinton. Thomas Carleton returned to England where he lodged with Lord Shelburne, who at the time was First Lord of the Treasury and Leader of the House of Lords.
