This book in the Civil War America series tells the story of the Army of Ohio from its formation in 1861, through the victory at Shiloh, and ultimate defeat at Perryville in 1862. Prokopowicz poses the question: what makes an army successful? Using the case of the Army of the Ohio, he argues that the way it is organized and recruited is more instrumental in the success of an army than its commanders or weapons.  (USS290, $37.50)
