Pitt's war around the world was largely successful. While a British invasion of Martinique failed, they captured Guadeloupe shortly afterwards. In India, a French attempt to capture Madras was repulsed. In North America, British troops closed in on France's Canadian heartland. A British force under James Wolfe moved up the Saint Lawrence with the aim of capturing Quebec. After initially failing to penetrate the French defences at the Montmorency Falls, Wolfe later led his men to a victory to the west of the city allowing the British forces to capture Quebec.
