The situation after the war was almost the same as before, but it set the stage for the Seven Years' War, which officially began in 1756, when Prussia and Austria again went to war. This time, however, France and Austria were allied and Britain and Prussia formed an alliance. French forces were defeated at the Battle of Rossbach in 1757. At the same time as the fighting in Europe, raiding parties composed of French-Canadian militiamen and Indians attacked English settlements in North America. This war, known as the French and Indian War, was the last of four wars that occurred in North America at the same time as a European conflict. However, by 1759, the British had gone onto the offensive in America and captured Quebec, the French colonial capital.
