Siege of Fort Ticonderoga Summary

The Siege of Fort Ticonderoga took place from July 2 to July 6, 1777. It was part of the Saratoga Campaign of 1777. After the American Invasion of Quebec failed, the Continental Army was forced to retreat to New York and took shelter at Fort Ticonderoga. In October 1776, the Battle of Valcour Island took place, where a small fleet of American ships, under the command of Benedict Arnold, slowed the British advance and forced them to put off the invasion of the Hudson River Valley until the spring of 1777. The British plan, which is known as Burgoyne’s Campaign of 1777, was led by Lieutenant General John Burgoyne. The plan was to capture Albany, New York, which would allow the British to cut New England off from the Southern Colonies. By July 1777, Burgoyne had advanced with his army to Fort Ticonderoga, which was under the command of Major General Arthur St. Clair. Burgoyne had around 8,000 men with him, and St. Clair had only 3,000. After Burgoyne placed some of his forces and artillery on a hilltop overlooking the fort, St. Clair decided to withdraw. There was very little fighting, although some British units did briefly follow after the Americans as they retreated. By July 6, the British occupied Fort Ticonderoga and Mount Independence, while the Americans made their way to Hubbardton and Skenesborough.
