When transplanted Texan Bob Seton arrives in Lawrence, Kansas he finds much to like about the place, especially Mary McCloud, daughter of the local banker. Politics is in the air however. It's just prior to the civil war and there is already a sharp division in the Territory as to whether it will remain slave-free. When he gets the opportunity to run for marshal, Seton finds himself running against the respected local schoolteacher, William Cantrell. Not is what it seems however. While acting as the upstanding citizen in public, Cantrell is dangerously ambitious and is prepared to do anything to make his mark, and his fortune, on the Territory. When he loses the race for marshal, he forms a group of raiders who run guns into the territory and rob and terrorize settlers throughout the territory. Eventually donning Confederate uniforms, it is left to Seton and the good citizens of Lawrence to face Cantrell and his raiders in one final clash.
Dark Command is a 1940 Crime western film starring Claire Trevor, John Wayne and Walter Pidgeon loosely based on Quantrill's Raiders during the American Civil War. Directed by Raoul Walsh from the novel by W. R. Burnett, Dark Command is the only film in which western icons John Wayne and Roy Rogers appear together, and was the only film Wayne and Raoul Walsh made together since Walsh discovered Wayne working as a prop mover, renamed him, and gave him his first leading role in the epic widescreen Western The Big Trail a decade before.
