War in America
After his victory at Fort LeBoeuf, Washington's forces built Fort Necessity at Great Meadows. The French captured it soon after. Washington resigned from service.
The war went back and forth from there. The British won at Acadia in Nova Scotia in 1755. The French won at Fort Duquesne. British Colonel William Johnson rallied back with a victory at Lake George.
Major blows were struck by the British in 1758. They seized Louisbourg, opening a path into Canada. From there, they took Fort Frontenac, cutting off French communication to all parts south. Then they made peace with the Iroquois, Shawnee and Delaware tribes, taking allies away from the French. After capturing Fort Niagara and Crown Point in 1759, the British held the entire western frontier.
British victories in Montreal and Quebec in 1760 marked the end of French control of Canada. French officially surrendered the territory on September 8. Practically speaking, the war ended September 15 when the British flag flew over Detroit. The French made some attempts to regain their forts and cities, but eventually had to give up.
