Philip Johnston was a son of a missionary. He grew up on a Navajo Reservation where he learned the Navajo dialect. During World War II there was an immense search for a form of communication. They needed a type of communication that would be unbreakable and completely unknown to enemies. Philip came up with the idea after reading an article. During World War I the Choctaw tribe was used as a form of communication. The Choctaw couldn't serve again as code talkers because enemies had already learned about the Choctaw dialect. Johnston knew the Navajo dialect was completely unknown, only the Navajo knew. The Navajo weren't allowed to speak using their language. The Navajo were the perfect plan of communication to join World War II as code talkers. Johnston proposed the idea to the United States Marine Corps. The Navajo then had to go through a series of tests to be qualified to be the code talkers.

In this letter, the general mentions that the dialect functions in a secret code. A secret code that was much needed during the war. During the war, the enemy needed not to be informed of their opponents' plans. The Navajo provided this secure communication. The code talkers were essential. It is important to know that 200 Navajo Indians were recommended to be enlisted. Many steps were taken to transmit messages. It would be a process of teamwork and communication. This exemplifies how the Navajo proved to be great communicators and essential to the war. The code talkers also had challenges. They had to learn new words that were very important, but they only had a few minutes to learn. Overall, these points help support the fact that the Navajo learned fast and were efficient. The Navajo were tested with speed and were able to quickly translate and communicate the messages.
