In 1758, a strong British force attacked Fort Carillon on Lake Champlain. General Montcalm was the French commander. Fort Carillon was strong enough that the smaller French force was able to defeat the bigger British force. The British withdrew, but attacked again the next year. This time the British commander was General Jeffery Amherst.
Amherst was successful. The British defeated the French. They changed the name of Fort Carillon to Fort Ticonderoga. It became an important military center in the French and Indian War. Fort Ticonderoga would also become important later, during America's war for independence.
The Battle for Quebec was the turning point in the war. Britain and France signed a treaty to end it in Paris in 1763. The British had won. They took control of the lands that had been claimed by France.
Britain now claimed all the land from the east coast of North America to the Mississippi River. Everything west of that river belonged to Spain. France gave all its western lands to Spain to keep the British out. Indians still controlled most of the western lands, except for some Spanish colonies in Texas and New Mexico.
