Battle Description

The Capture of Fort Ticonderoga was one of the earliest offensive actions of the Revolutionary War. On May 10, 1775, a small force of Patriot militia known as the Green Mountain Boys, led by Ethan Allen and Benedict Arnold, launched a surprise attack on the lightly defended British fort on Lake Champlain.

The British garrison, caught off guard and outnumbered, surrendered without resistance. The Patriots seized valuable artillery and supplies, which were later transported by Henry Knox to Boston and used to fortify Dorchester Heights during the Siege of Boston.

Outcome

• Outcome: Decisive Patriot victory; fort captured without bloodshed.
• Casualties: None reported on either side.

Significance on the Revolution

The capture of Fort Ticonderoga provided the Continental Army with a strategic stronghold and a critical supply of artillery. It also elevated the reputations of Ethan Allen and Benedict Arnold, though tensions between them foreshadowed future divisions. The fort’s location on Lake Champlain would later play a key role in controlling northern access routes and defending against British incursions from Canada.
