The siege of Louisbourg (8 June – 26 July 1758) was fought during the Seven Years' War on Cape Breton Island between an attacking British force and defending French and Mi'kmaq troops. The French attempted to send reinforcements by sea, but were not able to as the fleet was blockaded and defeated by the British. The battle ended French colonial dominance in Atlantic Canada and led to the subsequent British campaign to capture Quebec in 1759 and the remainder of New France the following year.
