Clad in the black robe of his priestly order and armed only with a crucifix, for more than a quarter of a century Father De Smet relentlessly tramped the American frontier to bring peace and religion to the tribes of the Pacific Northwest and the upper Missouri River country. In this biography, Robert Carriker describes De Smet’s love for the great American West and the native tribes who lived there, the Potawatomis, Flatheads, Coeur d’Alenes, Kalispels, Blackfeet, Yankton Sioux, and others to whom the Jesuit father carried Christianity. Soon the man called Black Robe became known throughout the mountains and plains as a man of peace and a friend of all Indians.
