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 were later transported to Boston by Colonel Henry Knox and used to fortify Dorchester Heights and break the standoff at the Siege of Boston.

Capture of the fort marked the beginning of offensive action taken by the Americans against the British. After seizing Ticonderoga, a small detachment captured the nearby Fort Crown Point on May 11. Seven days later, Arnold and 50 men intrepidly raided Fort Saint-Jean on the Richelieu River in southern Quebec, seizing military supplies, cannons, and the largest military vessel on Lake Champlain.
