A small unit, two companies strong, which were listed as the ninth and tenth companies of the Voltigeurs, but which were administered separately. Most of its men were English-speaking volunteers from the Eastern townships, unlike the French-speaking main body of the Voltigeurs. They operated alongside a group of Mohawk warriors at Lacolle, engaging in running firefights with the Americans during the latter's advance to the mill. The history and heritage of the Frontier Light Infantry is perpetuated within the Canadian Army by the Sherbrooke Hussars.
