Elmira Prison

Background

Elmira Prison was originally a barracks for "Camp Rathbun" or "Camp Chemung", a key muster and training point for the Union Army during the American Civil War, between 1861 and 1864. The 30-acre (120,000 m2) site was selected partially due to its proximity to the Erie Railroad and the Northern Central Railway, which crisscrossed in the midst of the city. The Camp fell into disuse as the war progressed, but its "Barracks #3" was converted into a military prison in the summer of 1864. It was the prison holding the largest number of Confederate POWs. Its capacity was 4,000, but it held 12,000 within one month of opening.
