Guy Carleton, 1st Baron Dorchester KB (3 September 1724 – 10 November 1808), known as Sir Guy Carleton from 1776 to 1786, was a British Army officer, peer, and colonial administrator. He served as Governor of Quebec twice, first from 1768 to 1778 and again from 1785 to 1795, while also holding the position of Governor General of British North America during his first term. The title of Baron Dorchester was granted on 21 August 1786. Carleton commanded British forces during the American Revolutionary War, notably defending Quebec against the 1775 rebel invasion and leading the 1776 counteroffensive that expelled the rebels from the province. As commander-in-chief of British forces in North America from 1782 to 1783, he is remembered for fulfilling the Crown's promise of freedom to slaves who joined the British side. He oversaw the evacuation of British forces, Loyalists, and over 3,000 freedmen from New York City in 1783, facilitating their relocation to a British colony. He tasked Samuel Birch with creating the Book of Negroes for this purpose. His younger brother, Thomas Carleton, also had a military and political career intertwined with Guy's, serving under him in Canada.
