This title provides a detailed examination of the defenses of the three largest fortified cities in Canada - Quebec, Montreal and Louisbourg - and also covers New Orleans in America. Quebec City is the best known and most impressive of the sites covered, and was the strongest of the fortresses of New France: besieged twice by the British (1690 and 1759) and once by the French (1760), it was captured in 1759 by General James Wolfe. Montreal was also strongly fortified and its strategic location ensured its prominence in the fur trade early on. Fortress Louisbourg was built as a large fortified naval station between 1720 and 1743 and saw significant combat action.
