[2][3] Discontent rose among many Native American tribes in the Great Lakes area, who wanted to expel the colonists in the region before more encroached on their lands.
In Pontiac's Rebellion, beginning in 1763, several tribes in the Great Lakes and Northwest area cooperated in establishing a pan-tribal confederation to counter British control of the region.
In the New York colony, Sir William Johnson, the Superintendent of Indian Affairs, had long advocated fair treatment of Native Americans but was only partially successful.
The escort party and teamsters, led by Porter Master John Stedman, were caught completely by surprise; animals broke into a stampede or were driven into the ravine along with their wagons and drivers.
The Seneca moved in to fight at close quarters, making musket fire useless, and only three of the party of 24 (including Stedman) managed to escape to Fort Schlosser for help.
Shortly after the battle, Johnson was told that the attack had been planned by a Seneca chief known as Farmer's Brother, who led a large band that supported Pontiac.
