On February 28, 1942, General Vogel tested the idea of the Navajo code talkers by "installing a telephone connection between two offices and wrote out six messages that were typical of those sent during combat. One of those messages read "Enemy expected to make tank and dive bomber attack at dawn." The Navajo managed to transmit the message almost verbatim: "Enemy tank dive bomber expected to attack this morning." The remaining messages were translated with similar proficiency, which duly impressed General Vogel.[10][3]

On 6 March 1942, General Vogel wrote a letter to the Commandant of the Marine Corps Thomas Holcomb recommending the Navajo Code Talkers.[11] The Navajo were recommended, in part, because Nazi Germany had not infiltrated the Navajo as they were the only "tribe that has not been infested with German students during the past twenty years. These Germans, studying the various tribal dialects under the guise of art students, anthropologists, etc., have undoubtedly obtained a good working knowledge of all tribal dialects except Navajo."
