On April 27, 1865, the steamboat Sultana exploded on the Mississippi River, killing 1,700 passengers. During the Civil War, the Sultana carried troops along the lower Mississippi. On this trip, the steamboat left New Orleans, stopping at Vicksburg for repairs. The captain took on many Union soldiers heading north as the government paid well for them. They were soon carrying more than six times capacity. Just above Memphis, the boiler blew, killing hundreds. Only 600 people survived.
