The great Sioux warrior-statesman Red Cloud was the only American Indian in history to defeat the United States Army in a war, forcing the government to sue for peace on his terms. At the peak of Red Clouds powers the Sioux could claim control of one-fifth of the contiguous United States and the loyalty of thousands of fierce fighters. But the fog of history has left Red Cloud strangely obscured. Now, thanks to the rediscovery of a lost autobiography, and painstaking research by two award-winning authors, the story of our nations most powerful and successful Indian warrior can finally be told.
