How we cite our quotes: (Chapter.Paragraph)
Quote #1
[A] thought slipped quietly into my head, then grew noisy: I need to learn English. What if I want—or need—to leave Navajo land someday? Knowledge of English would be crucial. (4.15)
As a young kid, Chester doesn't want to go to school. But he's smart enough to realize that English is important, and he'll only learn it if he goes to school. This quotation foreshadows Chester's work as a code talker. His knowledge of English—and Navajo, of course—will come in handy when he joins the Marines later.
Quote #2
I'd been caught speaking Navajo three days before. The Pima matron brushed my teeth with brown Fels-Naptha soap. I still couldn't taste food, only the acrid, bitter taste of the lye soap. (4.87)
Chester's punishment for speaking in Navajo at school is a reflection of the way that his schooling isn't just aimed at educating him. It's aimed at wiping out his Navajo culture.
Quote #3
The Marines talked to me, interviewing me in English about my family life and my education […] There were no interviews in Navajo. Apparently the Marines assumed we all spoke Navajo. (9.7)
Even though Chester has to suffer a lot in order to learn English at school, he reaps the rewards later when he can prove to the Marine recruiters that his grasp of English is just as strong as his grasp of Navajo. He'll need both languages for his work as a code talker.
Quote #4
Civil engineer Philip Johnston […] convinced Marine brass that the Navajo language—unwritten and spoken by only those who had lived among us Navajos—could be the basis for an unbreakable code. (9.19)
Here we get an understanding for why the Navajo language was chosen as the basis of the secret military code. It's unwritten and spoken by few people, so chances that the Japanese will manage to break it are slim.
Quote #5
How could we, twenty-eight of whom had never worked with the military, develop a code robust enough to be used in battle? (10.10)
This quotation expresses the self-doubt that the new Navajo Marines feel about developing the code. Can they live up to the difficult task that they've been assigned, especially given that most of them have never even had any experience in the military?
Quote #6
On that first day, we decided to use an English word […] to represent each letter of the English alphabet. Those words would then be translated into Navajo, and the Navajo word would represent the English letter. (10.13)
It's a good thing that Chester and his buddies have a good grasp of both English and Navajo, as they need both to develop the secret military code. While Chester was torn between the two languages growing up, here we see the two languages coming together.
Quote #7
In Navajo, no equivalent for words like "fighter plane" existed. We chose animals and other items from our everyday world that resembled the military equipment […] "fighter plane" was represented by the […] hummingbird. (10.48)
Chester and his buddies draw on the natural environment of Navajo land to come up with the code. This is another way in which their cultural and environmental heritage comes in handy in helping the Marines beat the Japanese.
Quote #8
[E]xpert code breakers from the United States military were assigned the task of breaking our code. They tried for weeks, but not one man met with any success in breaking the Navajo code. (10.63)
It's one tough code that the Navajo Marines come up with. The fact that even American code breakers can't break the code shows us what a good job the Marines have done.
Quote #9
A runner approached, handing me a message written in English. It was my first battlefield transmission in Navajo code. I'll never forget it [...] Enemy machine-gun nest on your right flank. Destroy. Suddenly, just after my message was received, the Japanese guns exploded, destroyed by U.S. artillery. (12.42)
This is the first time that Chester uses the code and witnesses it in action. It works! Chester will never forget this moment because it's the first time he sees all of his (and the other Navajo Marines') work paying off.
Quote #10
After being in operation for just forty-eight hours, our secret language was becoming indispensable. (12.66)
It becomes pretty clear pretty soon that the code is a weapon that the Marines simply can't do without. Which means, of course, that the Marines can't do without the Navajo code talkers. This quotation suggests just what an important role the code talkers played in the battle over the Pacific.
