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.
Fort Detroit the war and ceded the area to the United States. Some accounts say that only Fort Lernoult survived the 1805 fire that destroyed most of Detroit. It appears that no part of the original Fort Detroit remained after this time. Fort Lernoult was officially renamed as Fort Detroit in 1805, then renamed Fort Shelby in 1813. Soon after its use by the military ended, the fort was demolished by the City of Detroit in 1827. The second Hotel Pontchartrain, now named the Crowne Plaza Detroit Downtown Riverfront, is located on the former site of the fort. The Michigan Historic Marker
