Book excerpt: July 1-3, 1863. Two mighty armies clash outside the small town of Gettysburg, Pennsylvania. In the aftermath, tens of thousands lay dead or wounded, many of the poor souls left abandoned on the battlefield for weeks or days. The Battle of Fairfield, a short but brutal cavalry engagement, is fought nearby. The victims are brought to the Fairfield Inn, now hastily pressed into service as a field hospital, where the surgeons ply their bloody trade. The Army of Northern Virginia then retreats through this small town southwest of Gettysburg, where Generals Robert E, Lee and Jeb Stuart also stop at the Fairfield Inn. Originally built circa 1757, the Fairfield Inn was also a stop on the Underground Railroad, used to hide runaway slaves who were fleeing to freedom in the North. Little wonder that it developed a reputation for being haunted that persists to this very day. Shadow figures and apparitions roam the hallways. Footsteps and disembodied voices disturb the sleeping guests late at night. Doors open and close of their own accord. Cold spots abound and objects are moved by invisible hands. Join author Richard Estep ("The Haunting of Asylum 49," "The World's Most Haunted Hospitals") as he and a small team of paranormal investigators move into the Fairfield Inn and work to uncover its many secrets. Accompany them on a tour of the most haunted parts of the Gettysburg Battlefield, from Devil's Den and Little Round Top to the Slaughter Pen, the Valley of Death, and finally to Pickett's Charge, where the ghosts of long-dead Civil War soldiers are said to still march, eternal spirit guardians of America's most hallowed ground.
