This book tells the full story of the Comanche Code Talkers for the first time. Drawing on interviews with all surviving members of the unit, their original training officer, and fellow soldiers, as well as military records and news accounts, the author follows the group from their recruitment and training to their active duty in World War II and on through their postwar lives up to present. He also provides the first comparison of Native American code talking programs, comparing the Comanche Code Talkers with their better-known Navajo counterparts in the Pacific and with other Native American code talking in World Wars I and II, identifying two distinct forms of Native American code talking, examining the attitudes of the American military toward Native American code talkers, and assessing the complex cultural factors that led Comanche and other Native Americans to serve their country in this way.
