The collapse of the Women's Prison in Kansas City is also often believed to have made some people want to join in on the attack. To try to stop the Missouri guerrillas from being in Kansas, General Thomas Ewing, Jr. issued "General Order No. 10" in April 1863. This ordered anyone helping or comforting the Confederate guerrillas to be arrested. This mostly meant women or girls who were relatives of the guerrillas. Ewing sent the arrested people to some makeshift prisons in Kansas City. The women were then kept in two buildings which were either too small or too dirty. Then they were moved to an empty building at 1425 Grand Boulevard. This building was part of the estate of Robert S. Thomas, George Caleb Bingham's father-in-law. In 1861, Bingham and his family were living in the building. However, in early 1862, he and his family moved to Jefferson City when he was chosen to be the treasurer of Missouri. Bingham had added a third level to the building to use as a studio.
