Following the French defeat at the Battle of Fort Beauséjour and the start of the Great Expulsion in 1755, many Acadians formed guerrilla bands in the forests, often linking up with their ancient Mi'kmaq allies. These bands operated throughout Nova Scotia until the fall of New France, the most famous guerrilla being Joseph Broussard, also known as Beausoleil. Despite controlling many strongpoints like Halifax, Annapolis Royal and Fort Beausejour, the British were unable to completely pacify the region.
