The Bushwhackers (1951)

Plot here has Confederate veteran Jeff Waring arriving in Independence, Missouri shortly after the Civil War, and intending never again to use a gun. He finds that rancher Artemus Taylor, an arthritic despot, and his henchies, Sam Tobin and Cree, are forcing out the settlers in order to claim their land for the incoming railroad. The plot nearly predates "The Great Train Robbery" in age, but the gritty execution, and well-acted performances, take it out of the norm, way out, in a couple of instances. Brassy Myrna Dell is on hand as Taylor's independent daughter, only slightly less meaner than her father, and the always welcome Dorothy Malone is the pretty school marm on the side of good. Ireland's passive outlook on life changes before the end.
