World War I
3 In France during World War I, the 142nd Infantry Regiment, 36th Division, had a company of American Indians who spoke 26 languages and dialects. Two officers were selected to supervise a communications system staffed by 18 Choctaw individuals. The team transmitted messages relating to troop movements and their own tactical plans in their native tongue. Following the team’s success, soldiers from other tribes, including the Cheyenne, Comanche, Cherokee, Osage, and Yankton Sioux, also were enlisted to communicate as code talkers. Before their arrival in France, the Germans had broken every American code used, resulting in the deaths of many soldiers. However, the Germans never broke the American Indians’ “code,” and these soldiers became affectionately known as “code talkers.”
