Excellent point.
I did forget about the guerilla wars in Kansas and Missouri during that time.
TY for reminding me!
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.
