Set in the years leading up to the Civil War and its outbreak, Dark Command tells a fictionalized version of the story of William Clarke Quantrill, the schoolteacher-turned-renegade, whose raids -- ostensibly on behalf of the Confederacy -- turned Kansas into a charnel house. John Wayne plays Bob Setton, a young Texan who arrives in Lawrence, KS, in 1859 on his way west, partnered with George "Gabby" Hayes. He meets Marie McCloud (Claire Trevor) and her younger brother, Fletch (Roy Rogers), and takes a liking to them, especially Marie. His only competition for her is William Cantrell (Walter Pidgeon), the local schoolteacher, who has big ambitions in life. He is nominated for town marshal and seems a shoo-in, especially as his only rival is Bob Setton, who admits he knows nothing about the law and can't even read, but Setton wins with his honest, unpretentious speech. At the time, Kansas is riven by strife, as settlers from the North opposed to slavery and those from the South supporting it pour into the territory, and Setton has his hands full. His most difficult personal moment comes when he must arrest Fletch for shooting an anti-slavery farmer (Trevor Bardette) to death. Cantrell leads a campaign of terror against the jury, however, which finds the young man not guilty just as the Civil War breaks out. In the months that follow, Setton and his posse go after the raiders who are stealing and destroying huge amounts of property in Kansas on behalf of the Confederacy. He suspects Cantrell is their leader, but can't prove it, and has to tread carefully. As the raids worsen, and the war drags on -- even Marie's pro-Confederacy banker father is murdered during a run on his bank -- their conflict comes to a violent end as Cantrell launches an attack on Lawrence, vowing to destroy the town, with only Bob Setton and Cantrell's own mother (Marjorie Main) standing in his way. ~ Bruce Eder, Rovi
