In the first few months of the war in the Pacific during World War II, the Japanese broke all of the Allies' codes and always knew where the Americans would attack next. Japanese code breaking cost thousands of American lives until a missionary's son came up with an unusual solution and the United States Marine Corps recruited some unexpected allies. Navajo recruits (later nicknamed the "Code Talkers") developed a fast, efficient, unbreakable code using their unique native language coupled with word and letter substitutions. The Japanese never broke the code. This book is an introduction to the code, the creation of the code, and the men who developed and used it. The Navajo Code Talkers helped win the war in the Pacific using the very language that the government attempted to beat out of them as children in Indian schools.
