few days later, Nannie Harris died from her wounds. Survivors of the collapse included Jenny Anderson (crippled by the accident), Susan Anne Mundy Womacks, Martha "Mattie" Mundy, Lucinda "Lou" Mundy Gray, Elizabeth Harris (later married to Deal), and Mollie Grindstaff. Anderson's 13-year-old sister, who was shackled to a ball-and-chain inside the jail, suffered multiple injuries including two broken legs. Rumors circulated (later promulgated by Bingham who held a personal grudge against Ewing and who would seek financial compensation for the loss of the building) that the guards undermined the structure to cause its collapse. A 1995 study of the events and affidavits surrounding the collapse concludes this is "the least plausible of the theories." Instead, testimony indicated that alterations to the first floor of the adjoining Cockrell structure for use as a barracks caused the common wall to buckle. The weight of the third story on the former Bingham residence contributed to the resultant collapse. Even before the collapse of the jail, the arrest and planned deportation of the girls had enraged Quantrill's guerrillas; George Todd left a note for General Ewing threatening to burn Kansas City unless the girls were freed. While Quantrill's raid on Lawrence was planned before the collapse of the jail, the deaths of the guerrillas' female relatives undoubtedly added to their thirst for revenge and blood lust during the raid. Attack The attack was the product of careful planning. Quantrill had gained the confidence of many of the leaders of independent Bushwhacker groups and chose the day and time of the attack well in advance. Different Missouri rider groups approached Lawrence from the east in several independent columns. They converged with well-timed precision in the final miles before Lawrence during the pre-dawn hours of the chosen day. Many of the men had been riding for over 24 hours to make the rendezvous and had lashed themselves to their saddles to keep riding if they fell asleep. Almost all were armed with multiple six-shot revolvers. Henry Thompson, a black servant from Hesper, attempted to run on foot to Lawrence to warn the town of hundreds of raiders making their way toward Lawrence. Thompson made it as far as Eudora, Kansas before stopping from exhaustion. An unidentified man riding a chaise nearby rode by to ask Thompson if he needed help. Thompson replied that he had run from Hesper and needed to warn Lawrence. While Thompson and
