During the late summer of 1862, Confederate forces attempted a three-pronged strategic advance into the North. The outcome of this offensive, the only coordinated Confederate attempt to carry the conflict to the enemy, was disastrous. The results at Antietam and in Kentucky are well known; the third offensive, led to the devastating and little-studied defeats at Iuka and Corinth. Peter Cozzens presents the first book-length study of these two complex and vicious battles. Drawing on extensive primary research, he details the tactical stories of Iuka and Corinth, analyzing troop movements down to the regimental level.
