Capture of Fort Ticonderoga
The capture of Fort Ticonderoga occurred during the American Revolutionary War on May 10, 1775, when a small force of Green Mountain Boys led by Ethan Allen and Colonel Benedict Arnold surprised and captured the fort's small British garrison. The cannons and other armaments at Fort Ticonderoga were later transported to Boston by Colonel Henry Knox and used to fortify Dorchester Heights and break the standoff at the siege of Boston.
