In October of 1781, a detachment of the King's Rangers saw action as part of an expedition under the leadership of Brigadier-General Barry St. The corps was officially taken into the Northern Department in January of 1783, and subsequently disbanded later that year in Canada. After the war, over 200 members of this second battalion of the Rangers, including their commander James Rogers, stayed in Canada. A few remained in Quebec and some made their way to the Upper St. Lawrence. One officer, William Buell, founded Brockville.
Members are from Quebec, Ontario, Vermont, and New Hampshire.
