I want to know the answer to the following question:
What was the decisive battle in the Northwest territories against the native population there?
All the background I'm provided with is that "This provoked a war in the Northwest Territory in which the U.S. forces performed poorly; the Battle of the Wabash in 1791 was the most severe defeat ever suffered by the United States at the hands of American Indians.". Is that enough to answer the question?
Answer: no
