Provides an overview of the careers of the great military leaders and the critical political leaders of the American Civil War. Entries consider the leader’s character and pre-war experience, their contributions to the war effort, and the war’s impact on the rest of their lives. An assessment of their historical treatment puts their long-term reputations on the line, and results in a thorough revision of some leaders, a call for further study of others, and a reaffirmation of the accomplishments of the greatest leaders.
