On May 21, 1856, Jones and Donaldson came to Lawrence. A group of many men were on Mount Oread, and they had a cannon. Charles L. Robinson's house was taken over and used as Jones's headquarters. Jones's men guarded the roads that went in and out of Lawrence to stop people from leaving. Jones's men flew many flags, such as the state flags of Alabama and South Carolina. Many flags had anti-Free State or pro-slavery messages on them such as "Kansas the Outpost", "Southern Rights", and "Supremacy of the White Race").
