Fort Stanwix

Fort Stanwix is historically significant because of its successful defense by American troops during an August 1777 siege. The fort had been built by the British in 1758 at a strategic site along the water route from Lake Ontario to the Hudson River. After American forces captured and rebuilt the fort during the American Revolutionary War, they were besieged by a British army that invaded from Canada via Lake Ontario, hoping to reach the Hudson River. The British force abandoned the siege, a consequence that helped lead to the defeat of a larger British army during the Saratoga campaign.
