Battle Description

The Siege of Fort Ticonderoga occurred during the Saratoga campaign of 1777. British General John Burgoyne advanced south from Canada with a large force, aiming to control the Hudson River Valley and isolate New England. Fort Ticonderoga, held by American forces under General Arthur St. Clair, was a key defensive position.

On July 2, British forces began surrounding the fort. By July 5, they had placed artillery on Mount Defiance, a height that overlooked the fort and rendered it indefensible. Recognizing the danger, St. Clair ordered a nighttime evacuation on July 5–6, abandoning the fort without a fight.

Outcome

• Outcome: British victory; Americans abandoned the fort.
• Casualties:
  • American: Minimal during evacuation; some losses during British pursuit
  • British: Negligible

Significance on the Revolution

The loss of Fort Ticonderoga was a major blow to American morale and sparked outrage in the colonies. However, the strategic withdrawal preserved the Continental Army, which would later regroup and contribute to the decisive American victory at Saratoga. The event also exposed weaknesses in American fortification planning and command coordination, prompting reforms in military leadership.
