During World War Ⅱ, the U.S. Marines had a diffcult problem. They had to find a
way to keep their communication secret. Japan kept breaking U.S code. They knew
their enemy's plan. so they had time to prepare. The Americans became desperate as
the Japanese broke code after code. Then Philip Johnson had grown up on a Navajo
reservation. He knew the Navajo language, and he knew it was very hard to learn.
Fewer than 30 non-Navajo knew it. None of them were Japanese. Johnson thought
the Navajo could work well as a code. However, the Marine officer was not sure
about Johnson's idea. Even so, he agreed to give it a try. The marines had to try
something. Johnson set up a test. He showed what could be done in 20 seconds.
The Navajo could encode, transmit, and decode a three-line message. The officer
was impressed. He brought in two code breakers. They didn't even know how to
write down what they were hearing. Trying to translate it was impossible. The Navajo
"code tellers" had a job. The officer ordered 200 Navajos to be trained for
code-taking duty.
