The extant British Order of Battle ( basically the troop list) lists four British infantry units in addition to the Royal Marines. All of the infantry (the 4th (King's Own/Lancaster), 44th (East Essex) and 85th (Bucks Volunteers) Regiments of Foot and the 21st Regiment (Royal North British Fusiliers). Since the Marines did not recruit geographically, it is possible that some individuals were from Upper or Lower Canada. Canada, of course, did not exist as a separate political entity at that time.
