Speaking in Code

A group of Navajo men created a secret code that helped the United States win World War II.

The air was dusty with bullets. There was smoke everywhere. I saw an airplane get shot down.

February 19, 1945, was one of the scariest days of Thomas Begay’s life. He had just arrived on a small Japanese island called Iwo Jima. It was the site of one of the deadliest battles of World War II (1939-1945). 

Begay had an important job to do. He was one of more than 400 Navajo code talkers. They used a secret code created from their Native language to help win the battle—and the war.

The Code That Couldn't Be Broken

A Secret Weapon

Begay is a member of the Navajo Nation. He grew up in New Mexico, where his family spoke only Navajo. As a young boy, he knew just one English word—his first name.

That changed when he was about 13. That’s when Begay was sent to a boarding school. Hundreds of thousands of Native kids attended similar schools. They were forced to give up their cultures and were not allowed to speak their Native languages. 

While Begay was away at school, Japan attacked Pearl Harbor. That’s a U.S. military base in Hawaii. The next day, December 8, 1941, the U.S. entered World War II. 

Like many Americans, Begay wanted to join the fight. Nearly two years later, when he was 17, Begay enlisted in the U.S. Marine Corps. When he got to training camp, he found out he was going to be a code talker. 

U.S. troops needed a code to send messages about battle plans. It had to be hard to understand so the enemy could not decipher it. Since very few people spoke the Navajo language, the military decided it would be perfect for a code. Navajo men who were once punished for speaking their Native language would now use it to help the U.S. 

Begay spent months memorizing the code and creating new words. By the end of the war, the code had more than 500 words.

Into Battle 

In February 1945, Begay was shipped off to Iwo Jima. 

“I was scared that I was going to die,” he remembers.

Begay carried his heavy radio across the island as bullets flew by. In the first two days of battle, the code talkers sent more than 800 messages. 

“It was nonstop, calls coming in and going out all the time,” Begay says. 

The Japanese were never able to crack the code. After more than a month, the U.S. won the battle.

Honoring Heroes

Japan surrendered in August 1945, ending World War II. In 2001, Begay and the other Navajo code talkers were honored by Congress for their heroic service.

To this day, the Navajo code is the only spoken U.S. military code that has never been broken. Begay is proud of his role in World War II.

“I didn’t ask to be a code talker,” he says. “But I was a Navajo at a time when the United States needed Navajos.”
