Pontiac's War defeated them at the Battle of Bloody Run on July 31, 1763. Nevertheless, the situation at Fort Detroit remained a stalemate, and Pontiac's influence among his followers began to wane. Groups of Native Americans began to abandon the siege, some of them making peace with the British before departing. On October 31, 1763, finally convinced that the French in Illinois would not come to his aid at Detroit, Pontiac lifted the siege and removed to the Maumee River, where he continued his efforts to rally resistance against the British. Before other British outposts had learned about Pontiac's siege at Detroit,
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
