"Quantrill and his followers wanted to join the regular Confederate army because they knew what would happen to guerillas if they were taken prisoner. The Confederate Partisan Ranger Act was not recognized by the Federal government."
Yes,and that's when thing began to get bloody, when you outlawed Southern soldiers, like Quantrill's guerrillas, executed them upon capture (which was truly done, as everyone knows, who knows anything at all about the Border War); then, it was only natural to assume that it would become a case of tit for tat, and the guerrillas began killing Federal soldiers, in reprisal, upon capture. But though Union soldier unremittingly and without mercy executed guerrillas upon capture, even as late as 1864, when Quantrill seized the Union camp at Tuscumbia, Missouri, he paroled the ENTIRE command. That's the facts of the case, for those interested in the facts.
