When this book is described as "exhaustive," the adjective is fairly used. There is a wealth of detail within, to the point where individual characters become difficult to track. Some of the detail is good, such as the background on Indian policy, Custer's reputation within the Army, and the general movements of the 1876 campaign. Some is, to be honest, simply confusing, such as, again, the campaign plan. It would have benefited considerably from maps, both tactical and operational. Overall, however, it was a very good read and did a good job of not sparing or flogging anyone's reputation in discussion of the campaign.
