Remember the Sultana (2015)

"The Sultana was a river boat that exploded in 1865 killing many passengers, mostly Union Soldiers."

Over 2000 Union soldiers, passengers and crew were crammed aboard the steamboat Sultana, licensed to carry 376. Graft, greed, overcrowding, a poorly maintained boat, and the Mississippi River was swollen with spring snowmelt conspired together to create a disaster. On April 27, 1865, the boat’s boilers exploded, causing the worst maritime disaster in US history.
