A unique telling of Civil War military activity in 1861, The Glories of War focuses on the Union's invasion of Virginia from four directions; it is the first study of the four invasion corridors of the Civil War. The Union invasions mainly produced small battles and skirmishes, as well as widely celebrated heroes, that received national attention in both the North and South but are forgotten today. Major themes include combatants' romanticized visions of the "glories of war," as well as their subsequent disillusionment. Special emphasis is placed on military activity in western Virginia (modern West Virginia), which has received limited study. Extensive use of Union and Confederate newspapers, along with previously unused sources, brings new information to readers. The text is supplemented by maps depicting both overviews and details of military action.
