They were more reflective of the enmity between Misery and Kansas. Quantrill's Raiders, the Redlegs under Gen. Blunt, and the Jayhawkers were mostly guerrillas.
Quantrill's massacre at Lawrence could only be considered pure terrorism. The Confederate Army, with which Quantrill had aligned himself, was horrified. I think they killed 176 civilian men and boys in cold blood.
You could, and for all I know still can, buy a print of a picture of Lawrence after Quantrill and his guys finished with it. The caption is "Missouri 204 Kansas 0". The border war is alive and well still.
