As part of the campaign to invade Canada led by Richard Montgomery, Arnold led an expedition along the Kennebec, Dead and Chaudière rivers, arriving before Québec with only 700 of his original troop of 1100 men.
In the 18th century, Louisbourg was a fortified town and an important strategic capital in the French colony of Île Royale (Cape Breton Island). It was the scene of two major military sieges in the Anglo-French wars for supremacy in North America. The fall of Louisbourg to the British in 1758 paved the way for the capture of Québec and the end of French rule in North America. Today, Louisbourg is a national historic site and a popular tourist destination in Cape Breton.
