Who were the navajo code talkers and how did they the allies in world war 2

The Navajo code talkers were Native Americans recruited in the U.S. marines in order to speak to the enemies about their plans in attack, only the words spoken were based on the Navajo's own language making their plans unable to be comprehended by the enemy.
