This short narrative, delivered in the first person by the protagonist, George Dedlow, is a summary of the fictive experience of a wounded Civil War Captain. George's training as a surgeon was interrupted by the war and he entered the Union Army as an infantry officer. He was shot by musket in both arms, resulting in the amputation of one at the shoulder. After rehabilitation, he returned to the battlefield, only to lose both legs at mid-thigh and subsequently the remaining arm to infection.

The remainder of the story is that of a trunk, a body and head without extremities, who experiences all the manifestations of the phantom limb syndrome. The final episode is an encounter at a seance during which Dedlow is transiently reunited with his missing legs.
