ult. is that these demons claimed they were here to revenge the wrongs done their families by our men under Lane, Jennison, Anthony and Co." Charles L. Robinson, the first Governor of Kansas and an eyewitness to the raid, also characterized the attack as an act of vengeance: "Before this raid the entire border counties of Missouri had experienced more terrible outrages than ever the Quantrill raid at Lawrence... There was no burning of feet and torture by hanging in Lawrence as there was in Missouri, neither were women and children outraged." Robinson explained that Quantrill targeted Lawrence because Jayhawkers had attacked Missouri "as soon as war broke out" and Lawrence was "headquarters for the thieves and their plunder." Quantrill said his motivation for the attack was "to plunder, and destroy the town in retaliation for Osceola." That was a reference to the Union's attack on Osceola, Missouri in September 1861, led by Senator James H. Lane. Osceola was plundered, and nine men were given a drumhead court-martial trial and executed. Collapse of the Women's Prison in Kansas City The collapse of the Women's Prison in Kansas City is also often believed to have inspired some to join in on the attack. In a bid to put down the Missouri guerrilla raiders operating in Kansas, General Thomas Ewing, Jr. issued in April 1863 "General Order No. 10," which ordered the arrest of anyone giving aid or comfort to Confederate guerrillas. This meant chiefly women or girls who were relatives of the guerrillas. Ewing confined those arrested in makeshift prisons in Kansas City. The women were sequentially housed in two buildings which were considered either too small or too unsanitary, before being moved to an empty property at 1425 Grand. This structure was part of the estate of the deceased Robert S. Thomas, George Caleb Bingham's father-in-law. In 1861 Bingham and his family were living in the structure, but in early 1862 after being appointed treasurer of the state of Missouri, he and his family relocated to Jefferson City. Bingham had added a third story to the existing structure to use as a studio. At least ten women or girls, all under the age of 20, were incarcerated in the building when it collapsed on August 13, 1863, killing four: Charity McCorkle Kerr, Susan Crawford Vandever, Armenia Crawford Selvey, and Josephine Anderson—the 15-year-old sister of William T. "Bloody Bill" Anderson. A
