Fort Pitt (Pennsylvania) among Native Americans devastated the tribes of Ohio Valley and the Great Lakes areas. On August 1, 1763, most of the American Indians broke off the siege to intercept the approaching force under Colonel Bouquet. In the Battle of Bushy Run, Bouquet fought off the American Indian attack and relieved Fort Pitt on August 10. In 1772, after Pontiac's War, the British commander at Fort Pitt sold the building to two colonists, William Thompson and Alexander Ross. At that time, the Pittsburgh area was claimed by the colonies of both Virginia and Pennsylvania, which struggled for power over the region.
