After spending a few days driving though Montana and South Dakota, I bought a copy of Custer and Crazy Horse at the Mount Rushmore bookstore with the intention of expanding my admittedly limited knowledge of the important history associated with the two individuals and geographic areas associated with them. I was of course expecting to gain new insight to the Battle of Little Bighorn, but I unexpectedly learned much more. Though the parallel lives of Custer and Crazy Horse, Stephen Ambrose explores the wider cultural, economic, and military aspects of two very different societies increasingly at odds with one another.
