Gettysburg, Pennsylvania, is known as the location of one of the largest, most expensive, and deadliest battles of the American Civil War. There were an estimated 50,000 casualties during the bloody days at Gettysburg, and the nightmare of that battle never ended for some of the poor souls killed there. Some believe that the souls of those who suffered there may still roam across the hallowed grounds of the battlefield and throughout the town.
