Ozias M. Hatch, an advisor and close friend of President Lincoln. Throughout the war, Captain Hatch had shown incompetence as a quartermaster and competence as a thief, bilking the government out of thousands of dollars. Although brought up on courts-martial charges, Hatch managed to get letters of recommendation from no less reputable personages than President Lincoln and General Ulysses S. Grant. The letters reside in the National Archives in Washington, D.C. After the disaster, Reuben Benton Hatch refused three separate subpoenas to appear before Captain Speed's trial and give testimony. He died in 1871, having escaped justice because of his numerous highly placed patrons—including two presidents. Lack of accountability Despite the magnitude of the disaster, no one was ever formally held accountable. Captain Frederic Speed, a Union officer who sent the 1,953 paroled prisoners into Vicksburg from the parole camp, was charged with grossly overcrowding Sultana and found guilty. However, the Judge Advocate General of the United States Army overturned the guilty verdict because Speed had been at the parole camp all day and had not personally placed a single soldier on board Sultana. Captain George Williams, who had placed the men on board, was a regular Army officer, and the military refused to go after one of their own. Captain Hatch, who had concocted a bribe with Captain Mason to crowd as many men onto Sultana as possible, had quickly quit the service to avoid a court-martial. Captain Mason of Sultana, who was ultimately responsible for dangerously overloading his vessel and ordering the faulty repairs to her leaky boiler, had died in the disaster. In the end, no one was ever held accountable for what remains the deadliest maritime disaster in United States history. Legacy Monuments and historical markers to Sultana and her victims have been erected at Memphis, Tennessee; Muncie, Indiana; Marion, Arkansas; Vicksburg, Mississippi; Cincinnati, Ohio; Knoxville, Tennessee; Hillsdale, Michigan and Mansfield, Ohio. Remnants found In 1982, a local archaeological expedition, led by Memphis attorney Jerry O. Potter, uncovered what was believed to be the wreckage of Sultana. Blackened wooden deck planks and timbers were found about under a soybean field on the Arkansas side, about from Memphis. The Mississippi River has changed course several times since the disaster, leaving the wreck under dry land and far from today's river. The main channel now flows about east of its 1865 position.
