The Civil War prison camp at Elmira, New York, had the highest death rate of any prison camp in the North: almost 25 percent. Comparatively, the overall death rate of all Northern prison camps was just over 11 percent; in the South, the death rate was just over 15 percent. Clearly, something went wrong in Elmira. The culmination of ten years of research, this book traces the story of what happened. Author Michael Horigan also places the prison in the context of the greater Elmira community by describing the town in 1864 and explaining its significance as a military depot and draft rendezvous.
