Fort Venango, a small Britishfort built in 1760 near the site of Franklin, Pennsylvania, replaced Fort Machault, a French fort burned by the French in 1759 near the end of the French and Indian War. On June 16, 1763, during Pontiac's Rebellion, the fort was captured by Seneca/Mingo warriors. The 12 to 15 soldiers of the fort were killed outright, except for the commander, Lieutenant Francis Gordon, who was forced to write a letter detailing the Indians' grievances against the British. He was then slowly tortured and roasted to death at the stake, and the fort was burnt to the ground.
