Historians usually assume that the battles fought in Southwestern Virginia, Eastern Kentucky, and Eastern Tennessee played an insignificant role in the outcome of the Civil War. This book challenges that assumption. Focusing on the career of Colonel Andrew Jackson May, for whom the defense of the region was a personal crusade, it reveals that the victories which the Confederates won in this theater, allowing them to retain control of Preston’s Saltworks and the Virginia-Tennessee railroad, preserved the integrity of the Confederacy and thereby prolonged the war.
