The Confederate government abolished the Partisan Ranger act long before the war ended. If someone really was in Confederate service, there is usually a service file and records of their unit's operations. I can think of at least one Gainesville AL parole for a man who claiming to be a Confederate officer who really was a guerilla. "Colonel Robert Blackwell" terrorized Shelby County, AL, murdered at least twenty civilians there during the winter of 1864-65. Several months earlier he left middle Tennessee after murdering captured Federal soldiers. According to Confederate Veteran magazine, Robert Blackwell also shot and killed a Tennessee officer sent home on recruiting service in 1864.
