<P> Some marauding units became organized criminal gangs after the war . In 1882, the bank robber and ex-Confederate guerrilla Jesse James was killed in Saint Joseph . Vigilante groups appeared in remote areas where law enforcement was weak, to deal with the lawlessness left over from the guerrilla warfare phase . For example, the Bald Knobbers were the term for several law - and - order vigilante groups in the Ozarks . In some cases, they too turned to illegal gang activity . </P> <P> In response to the growing problem of locally organized guerrilla campaigns throughout 1863 and 1864, in June 1864, Maj. Gen. Stephen G. Burbridge was given command over the state of Kentucky . This began an extended period of military control that would last through early 1865, beginning with martial law authorized by President Abraham Lincoln . To pacify Kentucky, Burbridge rigorously suppressed disloyalty and used economic pressure as coercion . His guerrilla policy, which included public execution of four guerrillas for the death of each unarmed Union citizen, caused the most controversy . After a falling out with Governor Thomas E. Bramlette, Burbridge was dismissed in February 1865 . Confederates remembered him as the "Butcher of Kentucky". </P> <Ul> <Li> Washington, D.C </Li> </Ul> <Li> Washington, D.C </Li>
