During the early months of WWII, Japanese intelligence experts broke every code the US forces devised. They were able to anticipate American actions at an alarming rate. With plenty of fluent English speakers at their disposal, they sabotaged messages and issued false commands to ambush Allied troops. To combat this, increasingly complex codes were initiated. At Guadalcanal, military leaders finally complained that sending and receiving these codes required hours of encryption and decryption—up to two and a half hours for a single message. They rightly argued the military needed a better way to communicate.

When Phillip Johnston, a civilian living in California learned of the crisis, he had the answer. As the son of a Protestant missionary, Johnston had grown up on the Navajo reservation and was one of less than 30 outsiders fluent in their difficult language. He realized that since it had no alphabet and was almost impossible to master without early exposure, the Navajo language had great potential as an indecipherable code. After an impressive demonstration to top commanders, he was given permission to begin a Navajo Code Talker test program.

Their elite unit was formed in early 1942 when the first 29 Navajo Code Talkers were recruited by Johnston. Although the code was modified and expanded throughout the war, this first group was the one to conceive it. Accordingly, they are often referred to reverently as the "original 29". Many of these enlistees were just boys; most had never been away from home before. Often lacking birth certificates, it was impossible to verify ages. After the war it was discovered that recruits as young as 15 and as old as 35 had enlisted. Age notwithstanding, they easily bore the rigors of basic training, thanks to their upbringing in the southwestern desert.

The code they created at Camp Pendleton was as ingenious as it was effective. It originated as approximately 200 terms—growing to over 600 by war's end—and could communicate in 20 seconds what took coding machines of the time 30 minutes to do. It consisted of native terms that were associated with the respective military terms they resembled. For example, the Navajo word for turtle meant "tank," and a dive-bomber was a "chicken hawk." To supplement those terms, words could be spelled out using Navajo terms assigned to individual letters of the alphabet—the selection of the Navajo term being based on the first letter of the Navajo word's English meaning. For instance, "Wo-La-Chee" means "ant," and would represent the letter "A". In this way the Navajo Code Talkers could quickly and concisely communicate with each other in a manner even uninitiated Navajos could not understand.

Once trained, the Navajo Code Talkers were sent to Marine divisions in the Pacific theater of WWII. Despite some initial skepticism by commanding officers, they quickly gained a distinguished reputation for their remarkable abilities. In the field, they were not allowed to write any part of the code down as a reference. They became living codes, and even under harried battle conditions, had to rapidly recall every word with utmost precision or risk hundreds or thousands of lives. In the battle for Iwo Jima, in the first 48 hours alone, they coded over 800 transmissions with perfect accuracy. Their heroism is widely acknowledged as the lynchpin of victory in the pivotal conflict.

After the war, the Navajo Code Talkers returned home as heroes without a heroes' welcome. Their code had been so successful, it was considered a military secret too important to divulge. They remained silent heroes until more than two decades later. Even after declassification of the code in 1968, it took many years before any official recognition was given. In 2001, nearly 60 years after they created their legendary code, the Navajo Code Talkers finally received well-deserved Congressional Medals of Honor.

Now, in their 80's and 90's, only a few of these silent heroes remain. Many of their stories have yet to be documented for posterity. At the Navajo Code Talker Association, we are working to create a lasting record of the Navajo Code Talker legacy. Help us preserve the greatest stories never told.
