The siege of Fort William Henry (3–9 August 1757, French: Bataille de Fort William Henry) was conducted by a French and Indian force led by Louis-Joseph de Montcalm against the British-held Fort William Henry. This fort, located at the southern end of Lake George, on the frontier between the British Province of New York and the French Province of Canada, was garrisoned by a poorly supported force of British regulars and provincial militia led by Lieutenant Colonel George Monro. After several days of bombardment and increasing casualty rates, Monro surrendered to Montcalm, whose force included nearly 2,000 Indians from various tribes. The terms of surrender included the withdrawal of the garrison to Fort Edward, with specific terms that the French military protect the British from the Indians as they withdrew from the area. In one of the most notorious incidents of the French and Indian War, Montcalm's Indian allies violated the agreed terms of surrender and attacked the departing British column, which had been deprived of ammunition, as it left the fort.
