McKanes men follow Marshal Young and watch him survive an attack from the Comanches. They try to kill him but he manages to shoot them first. He mortally wounds Boyle and takes him to the town priest. Dying Boyle identifies the priest as Miguel Sebastian himself. Pardee arrives in town and inquires about Sebastian from a drunk named Pepe Diamond. He tries to kill Sebastian but he was gunned down by Young.Upon this new finding McKane was ordered to be in court. He sends his men to kill Sebastian, but he dodges them through underground passage. McKane plans a cattle stampede through town. In the trial, Sebastian testified that he was forced to give his land to McKane under death threat, and that Johnson refused to sign as a witness because it was extortion and collaboration with the enemy, but he was forced to sign. Sebastian was permitted to leave for Mexico, but Pardee tracks him and pushes him off a cliff and left him for dead. Judge Young ruled that the grant was illegal because McKane bargained with the enemy at war time, and that McKane will be sent to be courtmartialed. ........
