During the Civil War, the majority of the 583 Union generals studied here were afflicted by disease, injured by accidents, or suffered wounds. Following the war, they often suffered lingering diseases and the effects of unhealed wounds. Medical Histories of Union Generals includes a glossary of medical terms as well as a sequence of medical events during the Civil War listing wounds, accidents, and deaths. With his earlier book on Confederate generals, Dr. Welsh has produced a "must have" reference for medical and military historians.
