After the disastrous 1757 British campaigns (resulting in a failed expedition against Louisbourg and the Siege of Fort William Henry, which was followed by Indian torture and massacres of British victims), the British government fell. William Pitt came to power and significantly increased British military resources in the colonies at a time when France was unwilling to risk large convoys to aid the limited forces it had in New France. France concentrated its forces against Prussia and its allies in the European theatre of the war. Between 1758 and 1760, the British military launched a campaign to capture the Colony of Canada. They succeeded in capturing territory in surrounding colonies and ultimately Quebec. Though the British were later defeated at Sainte Foy in Quebec, the French ceded Canada in accordance with the 1763 treaty.
