The Lone Star Vigilantes.

It's Wild Bill Elliot as Wild Bill Hickok in the Columbia B-western Lone Star Vigilantes. Returning from Civil War duty, Hickok, Tex Martin and Cannonball find that their Texas home town is under the rule of Colonel Monroe, a bush-league dictator with his own police force. In true Hitlerian fashion, Monroe extorts huge sums of money from the populace, terrorizing them into silence. Our three heroes set about to put an end to Monroe's regime, with time out for Tex Ritter's musical interludes.
