This essay is based on the author's presentation at the Wachman Center's July 26-27, 2008 history institute, co-sponsored and hosted by the Cantigny First Division Foundation of the McCormick Tribune Foundation. For multiple reasons, one can say that the frontier wars are the most complex and difficult of all the nation's wars to teach. The conflict that raged for centuries on the North American continent still touches nerves in contemporary American academic, cultural, and political circles. As the debate over the status and treatment of American Indians goes on and becomes more politicized, the frontier wars represent a continuing source of friction in discussing American history, morality, consistency, military conduct, and government policy. American students need to know that there is more to this conflict than popular culture has shown. They need to know of the American Indians themselves and that the indigenous peoples represented varied, rich, and accomplished cultures that confronted European settlers with well-honed combat skills, sacrifice, and discipline. Students also need to learn that the natives' own failure to unify beyond family or tribal limits provided a key element to their ultimate defeat as well as the loss of their environment and way of life.
