The final period of this conflict was the French and Indian War, when French officers, Mi'kmaq, and Acadians carried out military strikes against the New Englanders, particularly after the deportation of the Acadians and the bounty proclamation of 1756. The Mi'kmaq and their French allies conducted the Northeastern Coast Campaign (1755) in Maine and extended this campaign into Nova Scotia, attacking civilians during the raids on Lunenburg. The British captured Louisbourg in 1758 and battled Quebec in 1759 and Montreal in 1760, and the French imperial power was destroyed in North America. With the loss of their French ally, the Mi'kmaq recognized the need for a new relationship with the British colonists.
