They devised a hundred-word dictionary of military terms, including ‘‘two-star chief ’’ for major general, ‘‘eagle’’ for colonel, ‘‘turtle’’ for tank, ‘‘sewing machine’’ for machine gun, and ‘‘pregnant airplane’’ for bomber.

World War II had no shortage of heroes, but the conflict likely would’ve ended on a completely different note for the United States without the efforts of the At the onset of the war, the U.S. found itself vulnerable to Japanese intelligence specialists who used their English-speaking soldiers to intercept the messages issued by the U.S. military.

From 1942 until 1945, Navajo code talkers participated in numerous battles in the Pacific, including Guadalcanal, Iwo Jima, Peleliu, and Tarawa. The Navajo code talkers even stymied a Navajo soldier taken prisoner at Bataan.

The developers of the original code assigned Navajo words to represent about 450 frequently used military terms that did not exist in the Navajo language.

The U.S. Marines knew where to find one: the Navajo Nation.

He also knew that Native American languages notably Choctaw had been used in World War I to encode messages.Johnston believed Navajo answered the military requirement for an undecipherable code because Navajo is an unwritten language of extreme complexity. Johnston staged tests under simulated combat conditions, demonstrating that Navajos could encode, transmit, and decode a three-line English message in 20 seconds.

Then, at Camp Pendleton, Oceanside, California, this first group created the Navajo code. In August 1942, at Guadalcanal, the Navajo Code Talkers were put to the test, not as code talkers, but as soldiers in battle. At Iwo Jima, Major Howard Connor, 5th Marine Division signal officer, declared, "Were it not for the Navajos, the Marines would never have taken Iwo Jima." The curious sounds were the … One estimate indicates that less than 30 non-Navajos, none of them Japanese, could understand the language at the outbreak of World War II.Early in 1942, Johnston met with Major General Clayton B. Vogel, the commanding general of Amphibious Corps, Pacific Fleet, and his staff to convince them of the Navajo language's value as code. Yes, the Japanese had a pretty good idea that it was Navajo. The Navajo Code Talkers could pass messages in as few as 20 seconds. According to the official Navajo Code Talkers website, indigenous words that sounded like military terms in English made up the code.“The Navajo word for turtle meant ‘tank,’ and a dive-bomber was a ‘chicken hawk.’ To supplement those terms, words could be spelled out using Navajo terms assigned to individual letters of the alphabet—the selection of the Navajo term being based on the first letter of the Navajo word’s English meaning.

It has no alphabet or symbols, and is spoken only on the Navajo lands of the American Southwest. This was far from an efficient way to communicate. Site created in November 2000. Convinced, Vogel recommended to the Commandant of the Marine Corps that the Marines recruit 200 Navajos.In May 1942, the first 29 Navajo recruits attended boot camp. “…I introduced this legislation – to salute these brave and innovative Native Americans, to acknowledge the great contribution they made to the Nation at a time of war, and to finally give them their rightful place in history.”The Navajo Code Talkers’ contributions to the U.S. military during World War II entered popular culture when the film How Navajo Soldiers Became World War II Code Talkers
