The 1777 Siege of Fort Ticonderoga occurred between 2 and 6 July 1777 at Fort Ticonderoga, near the southern end of Lake Champlain in the state of New York. Lieutenant General John Burgoyne's 8,000-man army occupied high ground above the fort, and nearly surrounded the defences. These movements precipitated the occupying Continental Army, an under-strength force of 3,000 under the command of General Arthur St. Clair, to withdraw from Ticonderoga and the surrounding defences. Some gunfire was exchanged, and there were some casualties, but there was no formal siege and no pitched battle. Burgoyne's army occupied Fort Ticonderoga and Mount Independence, the extensive fortifications on the Vermont side of the lake, without opposition on 6 July.
