Navajo Code Talkers
It is the most romantic story in American cryptology. To keep the Japanese from getting American secrets
in
World War II, Navajos - among the original Americans - spoke over the radio in their native tongue. In
World
War I, eight Choctaws manned trench telephones for the Army's 36th Division. According to Cryptologia
by
Stephen Huffman, trials were made during World War II with Comanches, Ojibwas, Oneidas, Sac-Foxes and
Muskogees. Most American cryptograms were not solved by the Japanese, who read at best a couple of
antiquated diplomatic codes and some low-level military cryptosystems.
The Navajo codetalkers provided secure, authenticated oral communications during battle. Indeed, the
usefulness of their information often expired within hours. They were first deployed on Sept. 18, 1942, on
Guadalcanal. In that island-hopping war they served as well on Bougainville, New Britain, Saipan, Tinian,
Guam, Peleliu, Iwo Jima and Okinawa.
During the first 48 hours of the Iwo Jima landing, the signal officer of the Fifth Marine Division
operated
six Navajo radio nets, whose
codetalkers
sent more than 800 messages without error. It was a codetalker message that reported that the
Marines
had reached the summit of Mount Suribachi, where the famous flag-raising took place. The Japanese never
interpreted a single message.
The idea of using Navajos to conceal the content of Marine messages came from Philip Johnston, a
missionary's son who grew up on their reservation speaking the language.
He knew:
- 1) that the 50,000-member Navajo tribe was a big enough large pool of English- and Navajo-speaking young men.
- 2) no Germans, Japanese or Italians had studied the language, whose complexities defy both interception and interpretation.
- 3) their language includes sounds that don't exist in German, Italian, Japanese or English.
He showed the Marines his idea on Feb. 28, 1942, four Navajos living in the Los Angeles area were given
five messages to send in Navajo. Although there were inaccuracies when a Navajo misheard the message, Maj.
Gen. Clayton B. Vogel, commander of the Amphibious Force of the Pacific Fleet, realized the potential of
theNavajos. He recommended to the commandant of the Marine Corps that they be recruited and trained for
secret spoken communications.
A chief advantage of the code talker system was its speed. Encrypting a written message, radioing it in
Morse code, transcribing the incoming text and decrypting it often took an hour or more. The Navajos
handled
a message in minutes.
About the Language: Learn about Tonal Languages
- 1) the word doc pronounced with a low tone means "not";
- 2) with a high tone, it means "and."
- 3) For military items, they chose words that evoked the objects themselves. Thus, tank was chay-da-ga-hi, or "tortoise." Observation plane was ne-ahs-jah, "owl." Brigadier general was so-a-la-ih, "one star." Soldiers were lei-cha-ih-yil-knee-hi, "dog faces." Some terms had to be arbitrary: din-neh-ih which means "clan," was used forcorps; has-clish-nih or "mud," for platoon.
- English and Navajo distinguish between unvoiced and voiced consonants (f is unvoiced, v is voiced)
- Navajo has ejective consonants, expressed with a burst of breath. An enemy wanting to decode messages in Navajo would first have to transcribe those unfamiliar sounds.
- Navajo verbs have different grammatical modes to denote different points in time.
- A Speaker must use one form if he himself was aware of the start of rain, another if he believes rain was falling for some time in his locality before he noticed it, and so on.
- The Navajo verb, is "like a tiny imagist poem."
na'il-dil means "You are accustomed to eat plural separable objects one at a time." This linguistic and phonetic complexity makes the languagenot only difficult for non-Navajos to understand but almost impossible to counterfeit. - The codetalkers spelled English words by using the Navajo word whose English translation had the initial letter needed. For a, for example, the codetalkers said wol-la-chee, "ant," or be-la-sa-na, "apple," or tse-null, "axe."
- If a Navajo term would serve, they used that: tse-ye-chee for "cliff." They used Navajo numbers. By the end of the war, the code dictionary ran eight typed pages and was used by about 420 Marine codetalkers in the Pacific.
NAVAJO HEROS
By the beginning of May, the first 29 had been inducted, and they received basic training and were sent to Camp Elliott, Calif., to prepare as codetalkers. Their language did not have words for "bomber," "tank," "colonel" and other military terms, and sometimes words had to be spelled out in English so that the English-speaking commanders could transmit and receive orders unambiguously. To overcome these difficulties, the Navajos devised a code. This had to be memorized, as no paper copies were to be carried into the combat zones where the codetalkers worked.
