Code Talker - Judith Schiess Avila

The Navajo code is the only unbroken code in modern warfare. It ensured the end of WWII by assuring the US victory in Japan. Only one original Navajo code talker still survives; Code Talker is his story. The Japanese had managed to crack every code the United States used. US military intelligence turned to the Navajo recruits and their native language to create a secret military code that the Japanese were unable to break and allowed embattled regiments of Marines to communicate quickly, concisely and above all, securely.
