Who scalped the French sentinel as the sisters approached Fort William Henry?

The French sentinel at Fort William Henry was scalped by a Native American warrior named Magua. Magua, a Huron chief, was allied with the French during the French and Indian War. His actions were part of a larger conflict involving British and French forces, as well as various Native American tribes. This event is notably depicted in James Fenimore Cooper's novel "The Last of the Mohicans."
