The Duff Green Mansion in Vicksburg, MS is widely believed to be haunted by multiple spirits, including a Confederate soldier, the ghost of the owners' daughter Annie, and even the former owner Mary Green herself. Guests and staff have reported seeing and hearing a variety of phenomena, such as disembodied footsteps and voices, floating figures, and the smell of gangrene in the Dixie bedroom. The former Civil War hospital setting and the home's long history contribute to the paranormal activity reported at the mansion. A Confederate soldier is frequently seen sitting by the fireplace, clutching his amputated leg. The spirit of Annie, the daughter of original owners Duff and Mary Green, has been heard bouncing a ball down the stairs and seen playing with a guest's young son. The former owner, Mary Green, is said to appear as a light green apparition floating past a door, or even as a full figure. Some believe Duff Green also haunts the property. Guests report smelling gangrene in the Dixie bedroom and feeling an invisible hand rub their shoulder. Footsteps, music, and voices are heard throughout the mansion, and doors are heard closing and swinging open on their own. In addition to the named ghosts, shadows are seen twirling in the ballroom. A breakfast cook felt an invisible hand on her shoulder, and guests have reported being tickled by a ghostly presence. The mansion served as a hospital for both Confederate and Union soldiers during the Siege of Vicksburg, leading to many deaths on the property.
