Hang Them All: George Wright and the Plateau Indian War - Paperbackby Donald L. Cutler (Author), Laurie Arnold (Foreword by) Col. George Wright's campaign against the Yakima, Spokane, Coeur d'Alene, Palouse, and other Indian peoples of eastern Washington Territory was intended to punish them for a recent attack on another U. S. Army force. Wright had once appeared to respect the Indians of the Upper Columbia Plateau, but in 1858 he led a brief war noted for its violence, bloodshed, and summary trials and executions.
