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 Confederate prisons in Cahaba, Alabama, and Andersonville, Georgia. They were en route from Camp Fiske in Mississippi to 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.
This worst the worst maritime accident in U.S. history.
The enormity of the disaster led quickly to investigations. By January 1866, a court-martial was convened to charge Captain Frederick Speed, the man who volunteered to coordinate the transfer of prisoners, with “neglect of duty to the prejudice of good order and military discipline.” Capt. Speed was the only person charged in the incident. He was found guilty, yet the charges were later dismissed by Judge Advocate General Joseph Holt.
