The United States got the land of the Northwest Territory from Great Britain. This land was part of the Treaty of Paris (1783) after the American Revolution. There were several defeats for the Americans. They include Harmar campaign (1790) and St. Clair's defeat (1791). St. Clair's defeat was a major defeat for the Americans. It is perhaps the greatest defeat in American military history.[2] Many American soldiers died. General Washington created a larger army. He made Anthony Wayne the new General. Americans won the last battle. This battle was the Battle of Fallen Timbers. The Natives had to give up their land in Ohio in the Treaty of Greenville (1795). In the Jay Treaty (1795), Natives gave up the lands around the British Great Lakes.
