Following the British conquest of New France, local militia units continued to be raised, and support British soldiers stationed in British North America. Members of the militia of the Province of Quebec first saw service with the British during Pontiac's War, when a battalion of three hundred "Canadien" volunteers took part in Brigadier General John Bradstreet's expedition to Detroit. The battalion was led by former members of the New French "troupes de la marine". British authorities also mustered the militia in Quebec during the American Revolutionary War, whose members constituted most of the defenders at the Battle of Quebec. However, Canadien militias saw little expeditionary action during the American Revolution, with Frederick Haldimand, the Governor of Quebec, uncertain if the "Canadien" militias would remain loyal should they encounter the French Army.
