Fortress of Louisbourg
In North America, France recognised British suzerainty over the Iroquois, and ceded Nova Scotia and its claims to Newfoundland and territories in Rupert's Land. The French portion of Saint Kitts in the West Indies was also ceded in its entirety to Britain. France retained its other pre-war North American possessions, including Cape Breton Island, where it built the Fortress of Louisbourg, then the most expensive military installation in North America.
