Fort William Henry was a British fort at the southern end of Lake George, in the province of New York. 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 position at 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. In 1757, the French general Louis-Joseph de Montcalm conducted a successful siege that forced the British to surrender. The Huron warriors who accompanied the French army subsequently killed many of the British prisoners. The siege and massacre were famously portrayed in James Fenimore Cooper's novel "The Last of the Mohicans".
