The British siege of Port Royal took place in 1710, ending French-rule in peninsular Acadia. The subsequent signing of the Treaty of Utrecht in 1713 formally recognized this, while returning Cape Breton Island (Île Royale) and Prince Edward Island (Île Saint-Jean) to the French. Despite the British conquest of Acadia in 1710, Nova Scotia remained primarily occupied by Catholic Acadians and Mi'kmaq, who confined British forces to Annapolis and to Canso.
