It's said that ghosts are the souls of those who died suddenly or tragically and are tied to the location of their demise for all eternity, unable to accept their death. If that's true, the battlefields strewn across America, should be some of the most haunted places in America. Few things were more sudden or tragic than taking a 24-pounder howitzer to the face while slowly walking toward a line of people who were supposed to kill you with rifles or bayonets. That being said, if ghosts do exist, the battlefield at Petersburg must be crawling with them.
