Henry Wirz was one of only two Confederates, tried convicted and executed for war crimes during the Civil War. The other was Samuel "Champ" Ferguson. Ferguson was a Confederate Guerrilla who admitted to killing more that 100 people, mostly civilians, who were sympathetic to the Union. He was tried for 53 murders and on October 10, 1865, was convicted and sentenced to death. He was hanged on October 20, 1865.
