"An outstanding addition to the literature of the war." —The NYMAS ReviewThis brilliant campaign nearly cleared the state of Rebels and changed the calculus of the Civil War in the Western Theater; however, few people today even know about it. The complex and fascinating campaign included deceit, hard marching, fighting, and incredible luck—both good and bad. Powell and Wittenberg mined hundreds of archival and firsthand accounts to craft a splendid study of this overlooked campaign that set the stage for the battles of Chickamauga and Chattanooga, the removal of Rosecrans and Bragg from the chessboard of war, the elevation of U. S. Grant to command all Union armies, and the early stages of William T. Sherman’s Atlanta Campaign.
