The Navajo were used to transmit and relay messages during WWll for the U.S. Marines. They were assigned two to a military unit with one to run the radio while the other one would relay and receive the message. The messages were sent in the Navajo code and translated into English. The code talkers improved the speed of encryption and decryption of communications in front line operations during World War II.
“We acted as coding machines, transmitting messages that would have taken a couple of hours in just a couple of minutes.”

The Code Talkers were first tested in November 1942 at Guadalcanal in the Solomon Islands as the United States were trying to oust the Japanese to keep them from being so close to Australia. It was described as a brutal fight that when the U.S. planes couldn’t radio positions to where the Japanese were it was the code talkers that was the only way of communication for the Marines for medicine, ammunition and food and their own positions. The Code Talkers proved they could make a difference and the Japanese fled the island by February.
“A runner approached, handing me a message written in English. [I transmitted the message to another code talker:] ‘Enemy machine gun nest on your right flank. Destroy.’ Suddenly, just after my message was received, the Japanese gun exploded, destroyed by U.S. artillery.”

Iwo Jima would be one of the costliest fights that would claim 6,800 Americans and 22,000 Japanese. It was here the Navajo Code Talkers proved just how important the code would be remembered.
“Were it not for the Navajos, the Marines would never have taken Iwo Jima.”

When the war came to a halt in August 1945 with the atomic bombs on Hiroshima and Nagasaki, Sam Sandoval remembers the best message he had to decode.
“The Imperial forces of Japan have surrendered.”
"The Navajo language, discouraged in the past, was instrumental in developing the most significant and successful military code of the time. At Iwo Jima alone, they passed over 800 error-free messages in a 48-hour period;
(A) So successful, that military commanders credited the code in saving the lives of countless American soldiers and the successful engagements of the U.S. in the battles of Guadalcanal, Tarawa, Saipan, Iwo Jima, and Okinawa;
(B) So successful, that some Code Talkers were guarded by fellow marines whose role was to kill them in case of imminent capture by the enemy; and
(C) So successful, that the code was kept secret for 23 years after the end of World War II."

The Navajo Code Talkers were treated with respect by other marines but their homecoming was not one of a hero, but completely the opposite. George Willie Sr. recalled arriving at a port where “a lot of people and balloons waiting for the ship,” yet the Navajo were “taken off the other side of the ship on wooden planks and immediately put on buses and sent home on trains. " Even when they returned to their communities they faced renewed discrimination with some businesses putting up signs reading “No dogs or Indians.” Heroes is so many ways, but since their code was still a secret, their importance would not be known until 1968 when it was declassified.
