After Union Brigadier General Thomas Ewing, Jr. ordered to put women in prison who had gave aid to Confederate guerrillas, the jail's roof fell. This killed five people. These deaths made the guerrillas in Missouri angry. On August 21, 1863, William Quantrill led Quantrill's Raid into Lawrence. He burned much of the city. They killed over 150 men and boys. Quantrill said the attack was okay to do because it would revenge for any bad things that the jayhawkers did to the Southerners.
