Considering how horrible the Civil War was, especially to those fighting and dying in it, it's not surprising that there are ghost stories about it.
Various things are covered including slaves being used to help the war effort, suicides, murders, accidents and how at times one side or the other had to leave their friends behind. Sometimes there was enough food, clothes and medical care to help them recover.
Sometimes they had nothing and they died.
The book does two things. One is discussing various paranormal sightings including photos, orbs, the feeling of clothes being touched, cold spots and actual ghosts.
The strength of the book, in my opinion, is the very detailed coverage of the various battles. In this form it's an excellent examination of the war in Alabama and its done in detail.
The two approaches work well together and make this a must-read book for anyone interested in the paranormal in relation to the Civil War.
