The Civil War produced the largest cavalry force ever raised in American history. In Civil War Cavalry, Earl J. Hess examines that force comprehensively and from new perspectives, challenging standard views of the war's mounted arm. Hess surveys the organization, training, administration, arming, and mounting of cavalry units and examines mounted troops' tactical formations and maneuvers. He addresses the nature of cavalry operations, discussing the mounted charge, dismounted fighting, long-distance raids, the varied types of weapons used by troopers, and the difficulty of supplying horses. Hess also brings concepts from the burgeoning field of animal history to argue that cavalry mounts exercised a degree of agency in shaping their role in the large military machine. Civil War Cavalry is a sweeping and innovative history, establishing a new criterion for understanding how Americans waged mounted warfare in the mid-nineteenth century.
