On June 19, 1763, about 250 Ottawa, Ojibwa, Wyandot, and Seneca warriors surrounded Fort Presque Isle (on the site of Erie, Pennsylvania), the eighth and final fort to fall. After holding out for two days, the garrison of about 30 to 60 men surrendered, on the condition that they could return to Fort Pitt. The warriors killed most of the soldiers after they came out of the fort.
