In the closing days of World War I, a group of Oklahoma Choctaws serving in the U.S. Army used their native language as the basis for secret communication among Americans, as Germans could not understand it. They are now called the Choctaw Code Talkers. The Choctaws were the Native American innovators who served as code talkers. Captain Lawrence, a company commander, overheard Solomon Louis and Mitchell Bobb conversing in the Choctaw language. He learned there were eight Choctaw men in the battalion.
