Edwin T Layton

Career

Edwin Thomas Layton was born on April 7, 1903 in Nauvoo, Illinois as a son of George E. Layton and his wife Mary C.Layton. Layton attended the United States Naval Academy at Annapolis, Maryland and graduated in 1924. Layton spent next five years with the Pacific Fleet aboard the battleship USS West Virginia and destroyer USS Chase.

In 1929, Layton was one of a small number of naval officers selected to go to Japan for language training. Significantly, on his voyage to Japan he met another young naval officer, Joseph J. Rochefort, assigned to the same duty. Both became intelligence officers, Rochefort specializing in decryption efforts, Layton in using intelligence information in war planning. Layton and Rochefort, both of whom were in Pearl Harbor, worked closely together in the months before the attack, among other things trying to work out aspects of the larger international context which Washington had decided would be handled by Washington alone, and even more closely after the war began, especially in the month before the Battle of Midway. They both made signal contributions to that victory.

Layton was assigned to the American Embassy in Tokyo as a naval attaché where he remained for three years. While in Japan, he met Admiral Isoroku Yamamoto on several occasions. The last four months he spent in Peiping (Beijing), China, as assistant naval attaché at the American Legation.

His linguistic ability and fluency in Japanese proved to be assets as his career progressed, even more so as World War II began in Europe.

During the 1930s, Layton served two tours of duty in the Navy Department’s Office of Naval Intelligence, in 1933 and again in from 1936 to 1937, but he also saw sea duty. He had a three-year stint in the battleship Pennsylvania where he received commendations for gunnery excellence. In 1937, he returned to Tokyo for two years as assistant naval attaché at the American Embassy. This was followed by a one-year tour of duty as Commanding Officer of USS Boggs (AG-19).

Exactly one year to the day before the attack on Pearl Harbor, Layton became Combat Intelligence Officer on the staff of Admiral Husband E. Kimmel, Commander-in-Chief of the United States Pacific Fleet, which had recently been moved from its base in San Diego, California to Pearl Harbor — over the objections of Admiral James O. Richardson, whom Kimmel replaced. Layton was in charge of all intelligence in the Pacific Ocean area.

Pearl Harbor, Coral Sea, Midway

Layton was a champion of using code-breaking information in war planning operations and had strong supporters in both Admiral Kimmel and Admiral Nimitz.

Layton's book describes how Kimmel and his army counterpart at Pearl Harbor, General Walter C. Short, the commanders there, were scapegoats for failures by higher-ups in Washington, D.C. Layton blames Admiral Richmond K. Turner in particular for monopolizing naval intelligence in Washington that would have alerted Kimmel and his staff to the imminence of attack and to the fact that Pearl Harbor could be a target of that attack.

Layton's argument is detailed and comprehensive, but in general, he maintains that although Washington was reading the highest level Japanese diplomatic code, Purple, little of this was ever made available to the field commanders, other than to MacArthur in the Philippines, who failed to act, not only on the Purple data, but even after he knew that Pearl Harbor had been attacked. The diplomatic information that they were denied not only contained data about the imminence of war, but also included messages sent from Honolulu to Tokyo by Takeo Yoshikawa, the spy sent to observe and report daily on the exact positions of ships in the harbor, using a grid system that was obviously designed for the purpose of targeting torpedoes and bombs. Those above Turner, including his boss, the Chief of Naval Operations, Admiral Stark, and even General Marshall, also come in for blame, though some details are still missing from the official record.

Forrest Biard, another naval linguist, one who was in the last group to be sent to Japan for language studies, worked for the Rochefort HYPO team as soon as he left Japan in 1941. HYPO was located in a basement, called "The Dungeon" by team members. In a speech to the National Cryptologic Museum Foundation, Biard describes Layton as the sixth member of the five-member team (Joseph J. Rochefort, Joe Finnegan, Alva B. Lasswell, Wesley A. Wright, Thomas Dyer) who produced the information that was vital to winning the Battle of Midway, following the Battle of the Coral Sea. He also characterizes Layton:

During May 1942, in particular, Layton and the Rochefort team were battling Washington as much as the Japanese – both as to where the next attack would occur and as to when it would occur. Washington said Port Moresby or the Aleutians in mid-June; Rochefort/Layton said Midway, first week in June. The story of how Rochefort's team prevailed is told in the Rochefort article, and in much greater detail in Layton's book. Nimitz deserves the highest praise for realizing that their analysis was sounder, something for which Layton deserves a very great deal of credit, and for risking the wrath of his boss in Washington, Admiral King, something for which Nimitz alone deserves a very great deal of credit. (Selecting Admiral Raymond Spruance to replace the hospitalized Admiral Halsey was also the right move, as was the earlier decision to retain Kimmel's intelligence officers.)

Layton remained on the staff of the Pacific Fleet until February 1945, followed by a three-year tour of duty as Commander of the U.S. Naval Net Depot at Tiburon, California. During this time, Admiral Nimitz, as a mark of his recognition of Layton's contributions, invited him to Tokyo Bay when the Japanese formally surrendered on September 2, 1945.

Intelligence work occupied Layton again, in the form of a two-year assignment as the first Director of the Naval Intelligence School in Washington D.C.

Korean War

Starting in 1950, Layton spent six months as Intelligence Officer on the staff of the Commandant, Fourteenth Naval District in Hawaii. His evaluative skills and keen interpretation of events were vital during the early stages of the conflict. In 1951, for a two-year period, he assumed his old position of Fleet Intelligence Officer on the staff of the Commander-in-Chief, Pacific Fleet.

In 1953, with the war over, he was assigned to the staff of the Joint Chiefs where he was Assistant Director for Intelligence, then Deputy Director. His last duty before retirement was Director of the Naval Intelligence School at the Naval Receiving Station, Washington, D.C.

Later life

Layton retired in 1959. He went to work for the Northrop Corporation as Director of Far East Operations in Tokyo, Japan, 1959 to 1963. He retired from Northrop in 1964 and moved to Carmel, California. Not until the 1980s were many of the documents about Pearl Harbor and Midway declassified. His book, And I Was There: Pearl Harbor and Midway — Breaking the Secrets was written with co-authors Roger Pineau and John Costello and was published in 1985, the year after Layton died. As appears in the books' acknowledgments, his wife, Miriam, assisted the publication of the book by not only encouraging the admiral to bring his story to print, but also by giving his collaborators access to his research notes and papers after his death.
