1. Code Talker: The First and Only Memoir by One of the Original Navajo Code Talkers of WW II

Chester Nez one of the original 29 Navajo code talkers, shares the fascinating inside story of his life and service during World War II.

During World War II, the Japanese had managed to crack every code the United States used. But when the Marines turned to its Navajo recruits to develop and implement a secret military language, they created the only unbroken code in modern warfare—and helped assure victory for the United States over Japan in the South Pacific.

I found this book very interesting but also very upsetting.  The way the US has treated our Native American's is truly a disgrace.  But regardless of how much white people abused them and criticized their culture because they are not like "us" the Navaho's who volunteered to serve during WW2 deserve to be called noble.  They developed an unbreakable code  and then went into battle on the front lines to implement it and saved many, many livesAnd let me go on to say they got precious little thanks and no recognition for their service until many years the war and by then many of them had passed away.
