The Sandbar Fight developed at a duel between Samuel Levi Wells III and Dr. Thomas Maddox on a Mississippi River sandbar near Natchez, Miss., on September 19, 1827. After the principals had exchanged shots without effect, a melee developed among their supporters arising from individual feuds. Colonel Robert Crain, a supporter of Maddox, killed General Samuel Cuny. Jim Bowie, a supporter of Wells, killed Major Norris Wright, Sheriff of Rapides Parish, with his knife, thus beginning his reputation as the South's most formidable knife fighter.
