After Union Brigadier General Thomas Ewing, Jr. ordered the imprisonment of women who had provided aid to Confederate guerrillas, tragically the jail's roof collapsed, killing five. These deaths enraged guerrillas in Missouri. On August 21, 1863, William Quantrill led Quantrill's Raid into Lawrence, burned much of the city and killed over 150 men and boys. In addition to the jail collapse, Quantrill also rationalized the attack on this citadel of abolition would bring revenge for any wrongs, real or imagined that the Southerners had suffered at the hands of jayhawkers.
