During the morning hours of September 17, 1868, on a sandbar in the middle of the Arikaree Fork of the Republican River in eastern Colorado, a large group of Cheyenne Dog Men, Arapaho, and Sioux attacked about fifty civilian scouts under the command of Major George A. Forsyth. For two days the scouts held off repeated charges before the Indian warriors departed. For nine days, the scouts lived off the meat of their horses until additional forces arrived to relieve them. Five scouts were killed and eighteen wounded during the encounter that later came to be known as the Battle of Beecher Island. Monnetts compelling study, a finalist for the Western Writers of Americas Spur Award in 1993, was the first to examine the Beecher Island battle and its relationship to the overall conflict between American Indians and Euroamericans on the central plains of Colorado and Kansas during the late 1860s. Focusing on the struggle of the Cheyenne Dog Men warrior society to defend the lands between the Republican River valley and the Smoky Hill River valley from Euroamerican encroachment, Monnett presents original reminiscences of American Indian and Euroamerican participants. Since its original release several developments and an important original source document have come to light and offer new information. The second edition presents and examines these new discoveries and developments that moderate the original interpretive causes and more modern effects of this historical episode. Scholars and general readers alike interested in this important episode in the postCivil War conflicts on the Great Plains and western history will find this new edition of The Battle of Beecher Island and the Indian War of 18671869 illuminating, surprising, and perhaps even controversial.
