In United States history, the story of Native Americans is predominantly tragic.

Settlers took their land, misunderstood their customs, and killed them in the thousands.

Then, during World War II, the U.S. government needed the Navajos' help. And though they had suffered greatly

from this same government, Navajos proudly answered the call to duty.

Communication is essential during any war and World War II was no different.

From battalion to battalion or ship to ship - everyone must stay in contact to know when and where

to attack or when to fall back.

If the enemy were to hear these tactical conversations, not only would the element of surprise be lost,

but the enemy could also reposition and get the upper hand. Codes (encryptions) were essential to protect these conversations.

Unfortunately, though codes were often used, they were also frequently broken.

In 1942, a man named Philip Johnston thought of a code he thought unbreakable by the enemy.

A code based on the Navajo language.

Philip Johnston's Idea

The son of a Protestant missionary, Philip Johnston spent much of his childhood on the Navajo reservation.

He grew up with Navajo children, learning their language and their customs.

As an adult, Johnston became an engineer for the city of Los Angeles but also spent a considerable amount

 of his time lecturing about the Navajos.

Then one day, Johnston was reading the newspaper when he noticed a story about

an armored division in Louisiana that was attempting to come up with a way to code military communications

 using Native American personnel. This story sparked an idea.

The next day, Johnston headed to Camp Elliot (near San Diego) and presented his idea for a code to

Lt. Col. James E. Jones, the Area Signal Officer.

Lt. Col. Jones was skeptical.

Previous attempts at similar codes failed because Native Americans had no words in their language for military terms.

There was no need for Navajos to add a word in their language for "tank" or "machine gun" just as there is no reason in English

 to have different terms for your mother's brother and your father's brother - as some languages do -

they're just both called "uncle." And often, when new inventions are created,

other languages just absorb the same word. For example, in German a radio is called "Radio"

and a computer is "Computer." Thus, Lt. Col. Jones was concerned that if they used any

Native American languages as codes, the word for "machine gun" would become the English word "machine gun" -

making the code easily decipherable.

However, Johnston had another idea. Instead of adding the direct term "machine gun" to the Navajo language,

they would designate a word or two already in the Navajo language for the military term. For example, the term for

"machine gun" became "rapid-fire gun," the term for "battleship" became "whale," and the term for "fighter plane" became

"hummingbird."

Lt. Col. Jones recommended a demonstration for Major General Clayton B. Vogel.

The demonstration was a success and Major General Vogel sent a letter to the

 Commandant of the United States Marine Corps recommending that they enlist 200 Navajos for this assignment.

In response to the request, they were only given permission to begin a "pilot project" with 30 Navajos.

Getting the Program Started

Recruiters visited the Navajo reservation and selected the first 30 code talkers (one dropped out,

so 29 started the program). Many of these young Navajos had never been off the reservation,

making their transition to military life even more difficult. Yet they persevered.

They worked night and day helping to create the code and to learn it.

Once the code was created, the Navajo recruits were tested and re-tested.

There could be no mistakes in any of the translations. One mistranslated word could lead to the death of thousands.

Once the first 29 were trained, two remained behind to become instructors for future Navajo code talkers

and the other 27 were sent to Guadalcanal to be the first to use the new code in combat.

Having not gotten to participate in the creation of the code because he was a civilian,

Johnston volunteered to enlist if he could participate in the program. His offer was accepted

and Johnston took over the training aspect of the program.

The program proved successful and soon the U.S. Marine Corps authorized unlimited recruiting for the Navajo code talkers program.

The entire Navajo nation consisted of 50,000 people and by the end of the war 420 Navajo men worked as code talkers.

The Code

The initial code consisted of translations for 211 English words most frequently used in military conversations.

 Included in the list were terms for officers, terms for airplanes, terms for months, and an extensive general vocabulary.

Also included were Navajo equivalents for the English alphabet so that the code talkers could spell out names or specific places.

However, cryptographer Captain Stilwell suggested that the code be expanded. While monitoring several transmissions,

he noticed that since so many words had to be spelled out, the repetition of the Navajo equivalents for each letter could possibly

offer the Japanese an opportunity to decipher the code. Upon Captain Silwell's suggestion, an additional 200 words and additional Navajo equivalents for the 12 most often used letters (A, D, E, I, H, L, N, O, R, S, T, U) were added. The code, now complete,

consisted of 411 terms.

On the battlefield, the code was never written down, it was always spoken.

In training, they had been repeatedly drilled with all 411 terms.

The Navajo code talkers had to be able to send and receive the code as fast as possible.

There was no time for hesitation. Trained and now fluent in the code, the Navajo code talkers were ready for battle.

On the Battlefield Unfortunately, when the Navajo code was first introduced, military leaders in the field were skeptical.

Many of the first recruits had to prove the codes' worth.

However, with just a few examples, most commanders were grateful for the speed and accuracy  in which messages

could be communicated.

From 1942 until 1945, Navajo code talkers participated in numerous battles in the Pacific,

 including Guadalcanal, Iwo Jima, Peleliu, and Tarawa.

They not only worked in communications but also as regular soldiers, facing the same horrors of war as other soldiers.

However, Navajo code talkers met additional problems in the field.

Too often, their own soldiers mistook them for Japanese soldiers.

Many were nearly shot because of this. The danger and frequency of misidentification caused some commanders

to order a bodyguard for each Navajo code talker.

For three years, wherever the Marines landed, the Japanese got an earful of strange gurgling noises

interspersed with other sounds resembling the call of a Tibetan monk and the sound of a hot water bottle being emptied.

Huddled over their radio sets in bobbing assault barges, in foxholes on the beach, in slit trenches, deep in the jungle,

the Navajo Marines transmitted and received messages, orders, vital information.

The Japanese ground their teeth and committed hari-kari."^*

The Navajo code talkers played a large role in the Allied success in the Pacific.

The Navajos had created a code the enemy was unable to decipher.
