“In the first six to twelve months of a war with the United States and Great Britain I will run wild and win victory upon victory. But then, if the war continues after that, I have no expectation of success.” – Admiral Yamamoto to Japanese prime minister Fumimaro Konoe.
The date of Admiral Yamamoto’s death was ironic.
Admiral Yamamoto was killed exactly one year after the famous Doolittle Raid on Tokyo on April 18, 1942.
It was like an omen.
The Japanese military and government did not disclose his death for about a month. When they did, they conducted a grand state funeral.
Here is a link to a Japanese video of his funeral. At the beginning, it shows the last known movie footage of him on Rabaul, waving to the pilots as they take off to attack Guadalcanal in Operation I boosting morale tremendously. There is also a glimpse of the only memorial statue of Admiral Yamamoto and a look inside his small home that is now in disrepair. During the funeral procession, it is very important to note you see Tokyo as it once looked before being leveled. I wonder if my grandparents, mom and aunt were in the crowds:
While his ashes were met in Tokyo by his widow (1), one half of his ashes remained in Tokyo, the other half taken back to his home town of Nagaoka. There, an unremarkable crypt of about three feet tall entombs one-half of his remains in a small family plot that is visited much more so by history nuts and the curious than by family and relatives.
In a bit of lost history, the funeral procession passed in front of his favorite geisha Chiyoko’s residence.
Similar to how WWII history has become to being taught here in America (meaning forgotten), Japan had chosen post-war to teach very little of WWII if anything. Because of this, many Japanese younger than say 55 years of age know very little about the war with America… except for the atomic and fire bombings.
For instance, my second wife and her mother never even heard of Iwo Jima. When I told them it was an island and part of the Tokyo prefecture, they were in disbelief. They didn’t even know there was a horrendous battle that took 30,000 young Japanese and American lives. Imagine that… but “the forgetting” is happening here in America too because of misguided emotional beliefs and attitudes of the teachers and school administrations.
Here in America, we have ships, airfields and streets named after heroes. Aircraft carriers USS Chester Nimitz, USS Dwight D. Eisenhower, USS George H. W. Bush, O’Hare International Airport, or John Basilone Road near Camp Pendleton.
Yamamoto has nothing. He is rarely even mentioned in Japanese textbooks. There are no ships, airfields or streets named after him. Just two unassuming crypts and they are rarely visited by offspring or family. There is a small museum I was able to see back around 2001 soon after it opened during a business trip but it was hard to find. Even the train conductor whom I asked for directions didn’t even know who Yamamoto was. He told me to go to the police kiosk and luckily, one of the officers heard of it and gave me directions – about a 15 minute walk. It does house a piece of the wing that was part of the Betty bomber he was shot down in. Oh, there is a small statue of him in his hometown near his crypt.
The lack of honorariums is an insult, in my opinion, as he gave his life to a war he knew he couldn’t win. He was simply loyal to his emperor. I also believe from my civilian’s chair that Yamamoto was one of the greatest prophetic naval minds in history – so much so that Nimitz viewed him as his greatest threat.
In his time, those in the Japanese military who wanted to see him assassinated believed he was “pro-American” or just a cowardly “dove”. I don’t see it that way. I believe he was a patriot, loved his country and was the consummate military man wearing the uniform of his country – just like Patton, Ike, and Nimitz. He simply did what he thought best for his country given his orders and conditions – that the pompous Army-led government wanted a war that Yamamoto knew they could not win. He therefore believed the only way to achieve this haughty vision of victory against the US and England was to execute a surprise attack on Pearl Harbor and disabling the US Navy’s Seventh Fleet.(2) He may have succeeded if Nagumo had indeed attempted to carry out Yamamoto’s full orders and battle plan. Nagumo failed to do so.
(Note: As an American, I fully accept that any attack on a country should be preceded by a declaration of war. However, just as I/we believe a declaration of war is necessary before hostilities, the samurai roots of Japan totally accepted surprise attacks as the norm. Just a fact.)
…but as a military leader, I feel for him. He knew Japan could not win. What was he to do? Step aside and let others lead the young men to their deaths under less competent leadership? Or lead them himself into a war they could not win and should not fight? Of course, he chose the latter and appropriately so. In my opinion, he should not be condemned because he did.
But it cost him his life.
The man whose name was his samurai father’s age at birth, the man who did handstands to break the thick air and bring laughter, the man who was a winner at gambling around the globe, the man who was nicknamed “Eighty Sen” by geishas… died fighting for the country who would then quickly bury him in theirlost history.
If he was not killed in the daring and risky attack hastily put together by the USAAF, what would have happened to him if he was alive on the day of surrender?
Would he have killed himself? Many did. He was the son of a respected samurai.
Or would he have surrendered like General Yamashita did in the Philippines only to be hung shortly thereafter as a war criminal in a hasty trial?
Would MacArthur have spared Yamamoto to be used as a liaison with his understanding of America and his fluent English during the Occupation? After all, he was revered in Japan as was Ike and Patton here. That may have been ideal but unlikely due to the immense hatred bred onto him by American propaganda.
We will never know.
Perhaps it was best he died a warrior while leading his troops.

This second video is the “official” national footage of the state funeral procession. You can glimpse the infamous General Tojo at about the 3:10 mark and his widow and three children at about the 3:20 mark:
(2) Against Admiral RIchardson’s stern advice to FDR for which he was fired, the US Seventh Fleet was moved out of San Diego to Pearl Harbor by FDR. Yamamoto, just like Richardson, saw it as a dumb military move. They were both right. This is one reason why I firmly believe FDR wanted Japan to attack the US and get us into a war which he campaigned against.
In Part 1 of “What Did FDR Know?”, I submitted tidbits that FDR – in spite of his campaign promises of not sending American boys to war – DID secretly plan with Churchill on how to get America into war without damaging their political images. Their secret discussions were nearly made public by Tyler Kent but he was tried secretly in a British court and admonished to prison until war’s end. Secretary of State Cordell Hull, on November 29, 1941, tried to leak to a major newspaper man intelligence gathered about the Imperial Japanese Navy heading towards Pearl Harbor.
In Part 2 of “What Did FDR Know?”, some history at Pearl Harbor before December 7, 1941 was provided as well as a brief history into cryptanalysis, the Japanese JN-25 and Purple codes and how the US Army and Navy broke them before and after Pearl Harbor.
In this Part 3, I will attempt to present evidence on intelligence gathered BEFORE the surprise attack on Pearl Harbor.
Part 4 will attempt to present evidence on the extent of our “listening in” on Imperial Japanese Navy battle plans post Pearl Harbor.
Part 5 will attempt to present evidence on the imprisonment of Japanese and Japanese-Americans in the “war relocation centers”, as FDR called them.
The goal is to allow you to come to your own conclusion as to “What Did FDR Know?”
We learned that the US Navy struggled to break the JN-25 code that was changed immediately before the attack. However, OP-20-G was able to decipher coded messages immediately prior to a reasonable extent. The number of JN-25 messages intercepted between just September 1 and December 4, 1941 numbered 26,581. Of these, 2,413 were released by the (now famous) NSA in 1979. Although there were more than 1,000 just between Tokyo and the attack fleet, only 20 are reportedly in the National Archives. (So much for the IJN operating under “strict radio silence” during the voyage to Pearl Harbor.)
The Purple code also became another critical source of intelligence, especially the week before Pearl Harbor. Luckily, we had been intercepting and deciphering them since September 1939… more than two years before Pearl Harbor.
Just what was transmitted by the Japanese diplomats about Pearl Harbor and intercepted through MAGIC? What other events occurred either in relation to the intercepts or the looming signs of the attack on Pearl Harbor? Please note that in 1941, they did not have emails, fax machines, TV, FedEx or SMARTphones. However, they did have TELEphones. Remember those things?
As shown above, there were more than 26,000 in JN-25 messages alone so going into detail about what was known in total would not be appropriate for this blog. However, if I were to summarize:
With respect to the Purple analog machines built from scratch, eight were made by the Naval Gun Factory in DC. Two each were used by OP-20-G and SIS; two were sent to the British. One was sent to Cavite in the Philippines. The last one was intended for Pearl Harbor – it was instead given to the British. It is likely true that even if Pearl had a Purple machine, it may not have been of too much value as it is reported the Japanese Consulate there did not have a deciphering machine.
Selected MAGIC ciphers were indeed placed into locked briefcases then shown to the top ten men in power over war – including FDR, just like in the movies.
Lt. Com. Arthur H. McCollum of Office of Naval Intelligence signed an eight point memo for FDR on how to coerce Japan into war with the US (aka “McCollum Memo”, the first page of which is shown at right). It was presented to FDR on October 7, 1940; FDR began implementing them the next day; all eight were eventually put into place.
A Purple message was intercepted on January 30, 1941. Tokyo instructed its diplomats to recruit agents covertly to spy on Allied movements and production. Issei and Nisei were mentioned for recruiting in the message. This espionage net could be for no other reason than to supply military information to Tokyo.
Per “President Roosevelt and the Coming of War 1941”, FDR actually proposed losing six cruisers and two carriers at Manila in order to get into war but was stopped by Navy Chief Stark.
On July 10, 1941, the US Military Attache in Japan reported the Imperial Japanese Navy was conducting secret training missions at Ariake Bay involving torpedo runs at moored ships.
After the Atlantic Conference and meeting with FDR, Prime Minister Churchill cabled his Cabinet on August 14, 1941 that FDR was intent on getting into the war.
A high level US Navy report was submitted on March 31, 1941 clearly stating that Pearl Harbor would be targeted, even so far as stating the Japanese Navy would utilize six carriers and surprise attack at dawn. That was because Japan strategically had few options and definitely could not have the Pacific Fleet to contend with.
A Korean agent by the name of Kilsoo Haan met with Eric Severeid of CBS that there was solid evidence that Japan would attack before Christmas. In October, Haan was able to convince US Senator Guy Gillette of these plans. Gillette alerted the State Department, Army and Navy Intelligence and FDR personally.
A coded message of September 24, 1941, from Japanese Naval Intelligence headquarters in Tokyo to the Japanese consul general in Honolulu, was intercepted and deciphered.(1) It requested the exact locations of all US Navy ships in Pearl Harbor; it even specifically asked to know if two ships were moored alongside each other. It was a map. Such detailed information would only be required if the Japanese were planning an attack on the ships at their moorings. The Japanese had not asked for such detailed information before. However, two top US officers, Stark and Turner, prohibited informing Pearl Harbor and Kimmel of this critical intelligence.
A JN-25 message was deciphered on November 1, 1941. It ordered the Japanese fleet practicing the attack to continue drills against anchored warships at at Ariake Bay. Words included “to ambush and completely destroy the US enemy.” References to using armor-piercing bombs and “near surface torpedoes” was also mentioned.
A Purple message of November 5th: Tokyo notified its Washington ambassadors that November 25th was the deadline for an agreement with the U.S. (to avoid war).
A Purple message of November 11th from Tokyo to its diplomats warned, “The situation is nearing a climax, and the time is getting short.”
Admiral Kimmel, following established Naval doctrines concerning unstable international conditions, ordered 46 (roughly one-half) of the Pacific Fleet out to sea in late November – specifically into the North Pacific. He did not inform Washington and when FDR found out, he ordered the fleet back to port under the guise such an exercise would provoke the Japanese. Undaunted, Kimmel had Admiral “Bull” Halsey put together a carrier-focused plan to protect Pearl Harbor which was never carried out. Instead, on November 26, 1941, Admiral Stark in Washington ordered Halsey to take to sea with his carriers; their mission was to ferry fighter planes to Midway and Wake Islands. Now you know why the carriers – the main target of the Imperial Japanese Navy – were “by luck” not at Pearl on December 7th.
A JN25 order of November 23 – “The first air attack has been set for 0330 hours on X-day.” (Tokyo time)
Another Purple message November 16th changed the deadline to November 29th. However, it stated, “The deadline absolutely cannot be changed. After that, things are automatically going to happen.”
The Japanese fleet left Japan (Hitokappu Bay) on November 25th. Remembering we were intercepting all Japanese Naval transmissions, about one hour after the Japanese attack force left port for Hawaii, the U.S. Navy issued an order forbidding U.S. and Allied shipping to travel via the north-west Pacific. All transpacific shipping was rerouted through the South Pacific. It should be easy to figure out why. If any commercial ship accidentally stumbled on the Japanese task force, it might alert Pearl Harbor. As Rear Admiral Richmond K. Turner, the Navy’s War Plans officer in 1941, stated: “We were prepared to divert traffic when we believed war was imminent. We sent the traffic down via the Torres Strait, so that the track of the Japanese task force would be clear of any traffic.”
British initially decrypted a message sent Nov. 19 setting up the “Winds” alert. The US decoded it Nov. 28. The message stated there would be an attack and that the signal would come over Radio Tokyo as a weather report – rain meaning war, east (Higashi no kaze ame) meaning the US.
On November 25, 1941, the great Admiral Isoroku Yamamoto himself, using the cracked JN-25 code, sent this message to his fleet: “(a) The task force, keeping its movements strictly secret and maintaining close guard against submarines and aircraft, shall advance into Hawaiian waters and upon the very opening of hostilities, shall attack the main force of the United States Fleet in Hawaii and deal it a mortal blow. The raid is planned for dawn on X-day — exact date to be given by later order. (b) Should the negotiations with the US prove successful, the task force shall hold itself in readiness forthwith to return and reassemble. (c) The task force will move out of Hitokappu Wan on the morning of 26 November and advance to the standing-by position on the afternoon of 4 December and speedily complete refueling.” This was decoded by the British on November 25 and the Dutch on November 27. WHEN it was decoded by the US is still a national secret; however, on November 26, ONI reported the concentration of units of the Japanese fleet at an “unknown port” ready for offensive action. ONI knew the fleet had been assembled at Hittokappu Bay since November 22, 1941.
In reaction to #17 above, Churchill himself sent FDR a secret message likely warning him about war erupting; this was presumably in response to British intelligence decoding Yamamoto’s message. (Note: Likely due to implications even today and in spite of the enumerable messages sent between them, this is the only message that has not been released.) C.I.A. Director William Casey, who was in the OSS in 1941, wrote, “The British had sent word that a Japanese fleet was steaming east toward Hawaii.”(2) In response to Churchill’s message, FDR secretly cabled him that afternoon, “Negotiations off. Services expect action within two weeks.” Note that the only way FDR could have linked negotiations with military action, let alone have known the timing of the action, was if he had read the message to set sail. In other words, the only service action contingent on negotiations was Pearl Harbor. Regardless, can it be coincidence that on Nov 26, Washington ordered both US aircraft carriers, the USS Enterprise and the USS Lexington out of Pearl Harbor? On board were 50 fighter planes diminishing Pearl Harbor’s already inadequate fighter protection.(3)
The FBI had put in wire taps on the Japanese Embassy phone lines. The FBI listened in on an uncoded Japanese telephone conversation on November 29 in which Special Envoy Saburo Kurusu asked, ‘Tell me, what zero hour is. Otherwise, I won’t be able to carry on diplomacy.” The voice from Tokyo (later identified as K. Yamamoto) said softly, ‘Well then, I will tell you. Zero hour is December 8 (Tokyo time, ie, December 7 US time) at Pearl Harbor.” (US Navy translation 29 Nov)
On December 1, 1941, the Japanese tanker Shiriya radioed she was “proceeding to a position 30.00 N, 154.20 E. Expect to arrive at that point on 3 December.” Key those coordinates into Google Maps yourself. This message in the National Archives destroys the myth that the attacking fleet maintained radio silence. Transmission serial numbers prove that the Striking Force sent over 663 radio messages between Nov 16 and Dec 7 or about 1 per hour. (The NSA has not released any raw intercepts because the headers would prove that the Striking Force did not maintain radio silence. On Nov 29 the Hiyei sent one message to the Commander of the 3rd fleet; on Nov 30 the Akagi sent several messages to its tankers.)(4) There are over 100 messages from the Striking Force in the National Archives.(5) Reports from Dec 5 show messages sent from the Striking Force picked up by Station Cast, P.I.
ONI located Japanese fleet on December 1, 1941 by correlating reports from the four wireless news services and several shipping companies that they were getting strange signals west of Hawaii. Remember Johann Ranneft visiting ONI and being shown the location of the Japanese fleet north-west of Hawaii in Part 1? The Soviet Union also knew the exact location of the Japanese fleet because they asked the Japanese in advance to let one of their ships pass.
On December 2 and 3, the passenger liner SS Lurline was en route from San Francisco to Honolulu. Its radio operator, following standard operating procedures, intercepted strong signals from the IJN fleet. The messages were so lengthy and numerous that the radio operator made out “JCS”, the call sign for the IJN HQ. The signals were plotted and showed the fleet’s location heading eastward and was north-west of Hawaii. When the USS Lurline docked in Hawaii on December 5, the radio intercept logs were immediately taken to the Office of Naval Intelligence at Kimmel’s Pacific Fleet HQs. The logs were never recorded as received nor ever seen again.
Ralph Briggs was a qualified Japanese-speaking radio intercept operator and was working at the Navy’s signals intercept station early in the morning of December 4. Buried inside the official IJN weather broadcast was the code “Higashi no kaze ame (東の風雨)”, or “East winds, rain”. (See #18 above.) The operators had been briefed to listen for those words. Per SOP, he logged it then transmitted via a secure channel to Commander Safford, in charge of the Fleet Intelligence Office in Pearl. To substantiate this, he was given four days’ leave as a reward.(6) On December 7, he was already back stateside in his Ohio home and was noted to have said something to the effect that the Japanese must have taken a licking (because he had intercepted the coded message and mistakenly believed the Navy was ready). After the attack, both the log and related communications were “lost” as well many other documents that were in safes.
While there were many other events and intercepted secret communications, the most famous one is the 14 part Purple transmission from Tokyo to Kurusu. It officially terminated diplomatic relations with the US, i.e., it is war. Amazingly, the first 13 parts had already been deciphered by MAGIC on December 6th. When Lieutenant Lester Schulz delivered to FDR his copy of the intercept later that day, Schulz heard FDR say to his advisor Harry Hopkins, “This means war.”
As the story goes, Kurusu failed to type up the Japanese ultimatum in time. However, Secretary of State Cordell Hull had already read the Purple intercept decoded the day before as did FDR. In essence, Hull had to look…surprised… when Kurusu handed him the ultimatum on December 7, 1941 albeit late. But at least, he was indeed angry.
We are now at war.
The above is by no means any-wheres near a complete accounting of the events leading up to Pearl Harbor. And yes, there will be blanks in information flows, other communications that will show things countering the above, etc. But it does show how a government can disguise the truth or create lies for whatever purpose…even if it involved the deaths of human beings.
You can imagine what is going on today. Benghazi. The complete killing of SEAL Team Six. Fast and Furious. It goes on.
But some questions may be in order to perhaps counter what you believed in or were taught until now? Perhaps you can ask yourself:
Did FDR blind the commanders at Pearl Harbor?
Were Kimmel and Short set up to be the fall guys by denying them very critical intelligence or lead them to believe war was not imminent?
Was Pearl Harbor alerted to the location of the attacking Japanese fleet?
Points to ponder, indeed.
And to close this (long) story, a Hollywood movie depicted Kimmel and Short receiving a telegram of all things alerting them of the possible attack on Pearl Harbor – many hours after it was over. That is true. However, how it became a late telegram is another story all together. By all accounts, Chief of Staff George C. Marshall orchestrated a delicate ballet to delay even sending that telegram for the critical few last hours. In fact, he was difficult to nail down during the critical hours before the attack, arriving late to his office to go over the critical Ultimatum. Although known for near photographic memory, he claimed he was horseback riding but his aides testified after the war that he wasn’t. Further, his aides urged him to contact Pearl Harbor but delayed that decision by reading then re-reading the ultimatum and then asking superfluous questions about what method of communicating with Pearl would be faster, for example – several times. He chose not to use the “telephone” nor use a fast, secure Navy system but sent the warning through commercial wire, of all things. Even then, the warning language he dispatched was watered down.
So what do you think?
What did FDR know? What do you think he did not know?
More to follow in Part 4 – key naval battles, code breaking and what really happened on the waters of the Pacific.
Henceforth, we would like to have you make reports concerning vessels along the following lines insofar as possible:
1. The waters (of Pearl Harbor) are to be divided roughly into five subareas (We have no objections to your abbreviating as much as you like.)
Area A. Waters between Ford Island and the Arsenal.
Area B. Waters adjacent to the Island south and west of Ford Island. (This area is on the opposite side of the Island from Area A.)
Area C. East Loch.
Area D. Middle Loch.
Area E. West Loch and the communication water routes.
2. With regard to warships and aircraft carriers, we would like to have you report on those at anchor (these are not so important) tied up at wharves, buoys and in docks. (Designate types and classes briefly. If possible we would like to have you make mention of the fact when there are two or more vessels alongside the same wharf.)”
There is nothing unusual about spies watching ship movements — but reporting precise whereabouts of ships in dock has only one implication. Charles Willoughby, Douglas MacArthur’s chief of intelligence and my dad’s big boss in the US 8th Army, later wrote that the “reports were on a grid system of the inner harbor with coordinate locations of American men of war … coordinate grid is the classical method for pinpoint target designation; our battleships had suddenly become targets.” This information was never sent to Kimmel or Short.
(2) Per his book, “The Secret War Against Hitler”.
(3) There are strategic evaluations asserting that not having US fighter aircraft sortied in great number against the invading Japanese fleet was “best” in the long run. Some armchair strategists claim that if the US carriers had “gone after” Nagumo’s fleet, indeed, our two vital carriers and her invaluable pilots would have been sunk, never to be recovered. That, however, is another story.
(4) The Hewitt Report, page 474.
(5) “Day of Deceit”, page 209.
(6) There is some bickering between opposing viewpoints as to the validity of this point. After the war, Japan stated it never issued such a broadcast. Other historians doubt Briggs’ testimony as there are no documents.
