Destruction of the Steamboat Sultana : the worst maritime disaster in American history / Gene Eric Salecker.

Enhanced descriptions from Syndetics:

The  Sultana  was a sidewheel Mississippi steamboat carrying almost two thousand recently-released Union prisoners-of-war back north at the end of the Civil War. At 2:00 a.m. on April 27, 1865, when the boat was seven miles above Memphis, her boilers exploded. Almost 1,200 people perished in the worst maritime disaster in United States history. Gene Eric Salecker covers this disaster in detail and dispels the many myths that have been connected to the  Sultana  for too long.

Almost every author who has written about the  Sultana has relied on the words of a few survivors or referred to the works of previous authors to get their story. Advancing the scholarship, the author has visited the National Archives in Washington, DC to comb through the handwritten transcripts of the three investigative bodies that looked into the disaster or poured over the handwritten testimony from the court-martial trial of Capt. Frederic Speed, the only person tried for the overcrowding of the vessel. In 1996, after extensive research and using the most current sources available at that time, Salecker wrote  Disaster on the Mississippi: The  Sultana  Explosion, April 27, 1865 . Still, there were inevitable omissions. After almost twenty-five years of continued research on the Sultana , and all those involved in the disaster, Salecker has gleaned unparalleled knowledge into every aspect of the disaster. His research, covering the National Archives, and thousands of pages of newspapers from around the world and government documents, including pension records and service records, has allowed Gene to tell the story of the  Sultana  as completely as possible. By bringing his research back to primary sources, Salecker dispels myths and adds to the story of the Sultana. 

In  Destruction of the Steamboat Sultana:The Worst Maritime Disaster in American History  paroled prisoners, civilian passengers, guards, crewmembers, rescuers, and eyewitnesses tell their stories in their own words. The true, and complete, story about the  Sultana  and the disaster has finally, and fully, been told.
