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,
Siege of Fort Stanwix surrendered after the Battle of Bemis Heights (second Saratoga). In an analysis after the surrender, Burgoyne noted that the failure of General William Howe to support him made it possible for Washington to divert resources from the area around New York City to assist both in the relief of Stanwix and at Saratoga. Fort Stanwix itself saw little action after the siege, although it was a dangerous and unpopular posting because of regular harassment by Loyalists and hostile Indians. In the spring of 1779 the Continental Army used the fort as a staging ground for the destruction of Onondaga Castle.
