Peter Cozzens here presents the first book-length study of the battles of Iuka and Corinth. Fought under brutal conditions and resulting in extremely heavy casualties relative to the numbers engaged - at Iuka, nearly one-third of those engaged fell - Iuka and Corinth proved to be two of the most vicious battles of the war. Drawing on extensive primary research, Cozzens details the tactical aspects of each battle, analyzing troop movements down to the regimental level.

In addition to a vivid and detailed battle narrative, Cozzens provides compelling portraits of the campaign's key leaders: Generals Grant, Rosecrans, Van Dorn, and Price. He exposes the consequences of their clashing ambitions and antipathies. Finally, Cozzens analyzes the larger, strategic implications of the northern Mississippi campaign, exploring the repercussions of the Confederate defeats suffered at Iuka and Corinth.
