During the 1758 Battle of Carillon, 4,000 French defenders were able to repel an attack by 16,000 British troops near the fort. In 1759, the British returned and drove a token French garrison from the fort. During the Revolutionary War, when the British controlled the fort, it was attacked on May 10, 1775, in the Capture of Fort Ticonderoga by the Green Mountain Boys and other state militia under the command of Ethan Allen and Benedict Arnold, who captured it in the surprise attack. Cannons taken from the fort were transported to Boston to lift its siege by the British, who evacuated the city in March 1776. The Americans held the fort until June 1777, when British forces under General John Burgoyne occupied high ground above it; the threat resulted in the Continental Army troops being withdrawn from the fort and its surrounding defenses. The only direct attack on the fort during the Revolution took place in September 1777, when John Brown led 500 Americans in an unsuccessful attempt to capture the fort from about 100 British defenders.
