In the years following independence, the newly-formed United States of America look westward for their expansion, hoping to conquer territory and sell off land to eager European settlers. Its first target is the vast, resource-rich 'Northwest Territory', stretching from the Appalachian Mountains to the Mississippi River. But this is not vacant land - thousands of native people from numerous tribes call these valleys and forests home, and will fight to protect it. As violence flares along the frontier and negotiations fail, President Washington and the US decide to take the territory by force... but they have fatally underestimated their enemy.
