Fort William Henry was a British fort at the southern end of Lake George, in the province of New York. It is the site of notorious atrocities committed by the Huron tribes against the surrendered British and provincial troops following a successful French siege in 1757. That event was portrayed in James Fenimore Cooper's novel The Last of the Mohicans.
The fort's construction was ordered by Sir William Johnson in September 1755, during the French and Indian War, as a staging ground for attacks against the French fort at Crown Point called Fort St. Frédéric. It was part of a chain of British and French forts along the important inland waterway from New York City to Montreal, and occupied a key forward location on the frontier between New York and New France.
