sabotaged Sultana by the use of a coal torpedo while they were drinking in a saloon. Louden, a former Confederate agent and saboteur who operated in and around St. Louis, had been responsible for the burning of the steamboat Ruth. In support of Louden's claim, what appeared to be a piece of an artillery shell was said to be recovered from the sunken wreck. However, Louden's claim is controversial, and most scholars support the official explanation. The location of the explosion, from the top rear of the boilers and far away from the fireboxes, tends to indicate that Louden's claim of sabotage of an exploding coal torpedo in the firebox was pure bravado. Thomas Edgeworth Courtenay, the inventor of the coal torpedo, was a former resident of St. Louis and was involved in similar acts of sabotage against Union shipping interests. However, Courtenay's great-great-grandson, Joseph Thatcher, who wrote a book on Courtenay and the coal torpedo, denies that a coal torpedo was used in the Sultana disaster. Two years earlier, in May 1886, came a claim that 2nd Lt. James Worthington Barrett, an ex-prisoner and passenger on the steamboat, had caused the explosion. Barrett was a veteran of the Mexican–American War and had been captured at the Battle of Franklin. He was injured on Sultana and was honorably discharged in May 1865. There is no apparent motive for him to have blown up the boat, especially while on board. In 1903, another person reported that Sultana had been sabotaged by a Tennessee farmer who lived along the river and cut wood for passing steamboats. After a few Union gunboats filled up their bunkers but refused to pay, the farmer supposedly hollowed out a log, filled it with gunpowder, and then left the lethal log on his woodpile. As stated in the 1903 newspaper article, the log was mistakenly taken by Sultana. However, Sultana was a coal-burning boat and not a wood-burner. An episode of the PBS series History Detectives that aired on July 2, 2014, reviewed the known evidence, thoroughly disputed a theory of sabotage, and then focused on the question of why Sultana was allowed to be crowded to several times its normal capacity before departure. The report blamed quartermaster Capt. Reuben Benton Hatch, an individual with a long history of corruption and incompetence, who kept his job through political connections: he was the younger brother of Illinois politician
