By most measures, the Confederate guerrilla insurgency in Missouri during the Civil War was the worst such conflict ever to occur on American soil. By one calculation, nearly twenty-seven thousand Missourians died in the violence. Historians have offered various explanations for the anomalously high level of guerrilla activity in Missouri, including the possibility that the violence was linked to thousands of court-ordered sales of property belonging to the state’s Confederate sympathizers, beginning in 1862 and continuing throughout the war. The property sales arose from court judgments for defaulted debts incurred early in the war to arm rebel troops.
