Reader recommendation: A Terrible Glory

I am thoroughly enjoying A Terrible Glory by James Donovan and also "The Last Stand" by Nathaniel Philbrick, two works on the Little Big Horn campaign. Both works try to explain some unresolved issues concerning Custer, the men under his command, and the roles of Indians. A really great work, "Lakota Noon" by Gregory Michno, gives very helpful understandings of how Indians saw the battle unfold and participated in it. All three works address uncertainties and contradictions in the campaign, leaving the reader with far a better understanding of the battle and the complex issues associated with the battle.
