The most fascinating chapters are at the start, the successive professional failures of Grant and Sherman prior to the war and their more or less stumbling into positions of command. The mid-bits are a gloss of Civili War history, rehash for anyone who's already soaking in this stuff anyway. Picks up again at the end with a vivid picture of the last weeks of the war, the atmosphere in Washington following Lincoln's assassination and the Grand Review of the victorious Union armies. Rapid fire epilogue blasts through Grant/Sherman's post-war careers as an obligation. Makes me want to read their memoirs for more detail.
