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 overcame a small British garrison at the fort and looted the personal belongings of the garrison. Cannons and other armaments from the fort were transported to Boston and used to fortify Dorchester Heights and break the standoff at the Siege of Boston.

After seizing Ticonderoga, a small detachment captured the nearby Fort Crown Point on May 11. Seven days later, Arnold and 50 men boldly raided Fort Saint-Jean on the Richelieu River in southern Quebec, seizing military supplies, cannons, and the largest military vessel on Lake Champlain.

Although the scope of this military action was relatively minor, it had significant strategic importance. It impeded communication between northern and southern units of the British Army, and gave the nascent Continental Army a staging ground for the invasion of Quebec later in 1775. It also involved two larger-than-life personalities in Allen and Arnold, each of whom sought to gain as much credit and honor as possible for these events.
