(1746–1805) Revolutionary army officer, born in Edinburgh Castle, Edinburgh, Scotland. Commissioned a colonel in the Continental army, Allan was appointed the superintendent of eastern Indians and he cultivated Indian support for the patriot cause. He occupied and defended Machias, on the far eastern frontier of Maine, against British attack from Nova Scotia, resulting in the eastern boundary of the United States being fixed at the St. Croix River (farther east) rather than at the Kennebeck.
