Most of Burgoyne's army had arrived in Quebec in the spring of 1776, and participated in the routing of Continental Army troops from the province. In addition to British regulars, the troops in Quebec included several regiments from the German principalities of Hesse-Cassel, Hesse-Hanau (from whose name the common reference of "Hessian" comes) and Brunswick-Wolfenbüttel under the command of Baron Friedrich Adolph Riedesel. Of these regular forces, 200 British regulars and 300 to 400 Germans were assigned to St. Leger's Mohawk valley expedition, and about 3,500 men remained in Quebec to protect the province. The remaining forces were assigned to Burgoyne for the campaign to Albany. The regular forces were supposed to be augmented by as many as 2,000 militia raised in Quebec; by June, Carleton had managed to raise only three small companies. Burgoyne had also expected as many as 1,000 Indians to support the expedition. About 500 joined between Montreal and Crown Point.
