Nathan Bedford Forrest

Amid the aristocratic ranks of the Confederate cavalry, Nathan Bedford Forrest was untutored, all but unlettered, and regarded as no more than a guerrilla. His tactic was the headlong charge, mounted with such swiftness and ferocity that General Sherman called him a "devil" who should "be hunted down and killed if it costs 10,000 lives and bankrupts the treasury." And in a war in which officers prided themselves on their decorum, Forrest habitually issued surrender-or-die ultimatums to the enemy and often intimidated his own superiors. After being in command at the notorious Fort Pillow Massacre, he went on to haunt the South as the first grand wizard of the Ku Klux Klan.
