Rebels against the Confederacy - Myers, Barton A. (Washington and Lee University, Virginia)

This book analyzes the secret world of hundreds of white and black Southern Unionists as they struggled for survival in a new Confederate world, resisted the imposition of Confederate military and civil authority, began a diffuse underground movement to destroy the Confederacy, joined the United States Army as soldiers, and waged a series of violent guerrilla battles against other Southerners.
