When the boiler exploded aboard the steamer Sultana on April 27, 1865, more than 1,700 people lost their lives. Most of those aboard were recently released Union prisoners from the Confederate prisons in Cahaba, Alabama, and Andersonville, Georgia. They were bound for Camp Chase, Ohio, but the explosion occurred only a few hours into the journey. In addition to the faulty boiler, the ship was also grossly overburdened with 2,200 passengers on a vessel built to carry 376.
