After the British had taken Quebec City, it was only a matter of time before the French stronghold of Montreal would fall. On September 6, 1760, British forces of nearly 18,000, under the command of Jeffrey Amherst besieged Montreal. Only 2,100 French soldiers were left to defend the city. After three days, they were forced to surrender, and Montreal was in the hands of the British. The siege of Montreal marked the end of French rule in North America. The war officially ended on February 10, 1763, with the signing of the Treaty of Paris. As a result of the war, France gave up nearly all of its territory in North America. In addition, they agreed not to build any military establishments in India, which made England the dominant power there.
