1777 - July 5 - St. Clair surrenders Fort Ticonderoga to the British

In July 1777, during the American Revolutionary War, the surrender of Fort Ticonderoga to the British forces under General John Burgoyne was a significant event. The fort, located in present-day New York, was a key strategic stronghold guarding the southern access route to Canada. General Arthur St. Clair, commanding the American forces, faced mounting pressure as Burgoyne's army advanced southward from Canada.

St. Clair's position at Fort Ticonderoga was precarious due to its vulnerability to a siege and the lack of sufficient troops and supplies. Recognizing the imminent threat, St. Clair made the difficult decision to evacuate the fort to prevent its capture and destruction. On July 5, 1777, St. Clair and his forces abandoned Fort Ticonderoga, allowing the British to take possession without resistance.
