    Montcalm's forces moved south in late July 1757, with Lévis blocking the road to Fort Edward on 3 August.

Background and detail

Strategic Context. Fort William Henry, built in 1755 at the southern end of Lake George, served as a British defensive position. Montcalm sought to capture it to prevent British attacks on Fort Carillon. The fort was garrisoned by British regulars and militia under Lieutenant Colonel George Monro, though it was not fully equipped to withstand artillery.

Violation of Terms. Surrender terms allowed the British to withdraw to Fort Edward under French escort. However, Montcalm's Indian allies violated these agreements, attacking the departing column. They killed and scalped wounded British soldiers in the fort and plundered the entrenched camp, despite French efforts to stop them.
