I've been reading some WWII history today, and I thought I'd share some tidbits with you.

The mastermind behind Japan's attack on Pearl Harbor was its naval chief, Admiral Isoroku Yamamoto. He had done some schooling for a few years in the U.S. and knew our ways well; he also spoke fluent English.

He had advised against the raid on Pearl Harbor, estimating correctly that Japan could never overcome the massive resources of both the U.S and Britain. However, he was overruled and then did his duty to plot the very successful attack.

The U.S. was determined to kill him, and was even advised against it by our British allies, believing it would viewed as an assassination. The legal minds in the U.S. thought otherwise, and viewed him simply as an enemy combatant.

In 1943, it was top secret that we had broken the Japanese codes, and this was never discovered by the Japanese until well after the war was over.

In Mid-April of 1943, we intercepted a message that Yamamoto was to visit his troops on Bougainville in the Pacific Ocean on April 18. President Roosevelt was advised of this, and gave Admiral Nimitz, our top naval officer in the Pacific, the go-ahead to get Yamamoto.

Yamamoto was to fly in a twin-engine "Betty" bomber to Bougainville, and the exact time of his arrival was disclosed in a coded message which we intercepted.

The Navy did not have planes that could make the round trip to Bougainville, so the U.S. Army Air Corps was given the assignment. They had P-38 twin-engine fighters, which with fuel drop tanks could do the job, with time to spare for engagement over Bougainville. Quite a number were dispatched for a "meeting" with Yamamoto, who was always fastidiously punctual for his meetings.

Two "Betty" bombers left for Bougainville, one carrying Yamamoto, and the other acting as decoy. The two bombers were escorted by a good number of Zero fighter aircraft.

The P-38s were ready and waiting, but were surprised by there being two bombers, and the large number of Zeros. We attacked both bombers, which split in different directions when they realized we were there.

Army First Lieutenant Rex Barber got behind the Yamamoto bomber and let loose with cannon and 50-caliber machine guns, striking the fuselage and the right engine, which burst into flame. He got so close that debris from the burning bomber struck his P-38, and he veered away at the last moment.

Yamamoto personally took two .50 caliber slugs, one through a shoulder, and the other one striking him in the mouth of his turned head, and exiting his skull on the other side, killing him instantly. The bomber nose-dived into the ground and broke up. Yamamoto was 59 years old at the time of his death.

The event raised U.S. morale incredibly, and we viewed it as just retribution for Pearl Harbor. The Japanese took the event hard, and their successes in the Pacific came to a roaring halt.

This was a major event of the war, and Navy crosses were first handed out to the participants (even though they were Army guys), fearing that the Medal of Honor might tip the Japanese that we had prior knowledge of Yamamoto's location. Lt. Barber was later given the Medal of Honor, as were others in the group. Only one P-38 was destroyed by Zeros, and its pilot was never recovered.

Here's an artist's perception of the encounter, made to be accurate in every detail.

Thought I'd share the story with you.

Admiral Isoruku Yamamoto


First Lt. Rex T. Barber is on the viewer's right.

Hey war is hell. If I had the power to make that "go decision" I would not have hesitated a iota. High rank yes, but reducing that down to a common denominator he was just another Japanese combatant.
 
Great mission. To call it "Magic" would be accurate. The Allies code breaking achievements were monumental, but... it took men like these piolets (in all services, all over the world) who would aggressively go deep into enemy territory and do the job. Great mission.
 
It is noteworthy that we would use source intelligence, the breaking of the code, and risk losing it to a simple code change. The Japanese must have at least suspected that we had broken the code. Spying back and forth between the U.S. and Japan was intense. Is it possible they simply assumed that a random patrol of P-38's ambushed Yamamoto? There were intelligence blunders worse than this throughout the war, the nature of the fog of war. In WWI the Lusitania was not told of German submarine activity near Ireland for fear of revealing that we had broken their cyphers. That didn't end well.
 
Our neighbor, when we were kids, was a decorated P-38 pilot in the Pacific theater. He was proud of his service, and loved showing us kids photos, ribbons, medals, etc. And he loved to fly , and owned and frequently flew his Bonanza for business and recreation until his death from cancer at 88. The story of the shooting down of Yamamoto was one of his favorites; he knew and flew with both pilots.

And as Paul Harvey used to say, "Here's the rest of the story." or something like that. ;) I read about this quite a few years ago and they way they addressed this and deflected the Japanese from thinking we were reading their coded messages was that they kept sending P-38 patrols out there for some weeks after the shootdown mission, to make it seem like just a normal assignment of patrol areas to the P-38 squadrons. They weren't about to jeopardize reading the Jap's messages by doing bonehead moves like sending out just 1 patrol on the day that the top Jap brass was supposed to be visiting and then stop.
 
Odd that the Brits would worry about polishing off Yamamoto. They were keen to do away with Rommel. "Political" considerations didn't stop them from trying that. Likewise the Germans made an effort to kill high Allied commanders towards the end of the war in Europe, but I don't think they had any success. There is no point in mentioning specifics of the brutality of the Japanese before and during the war. It's not popular. War should be all about causing harm to your enemy. Eliminating high officers should be nothing more than a cost vs. effect calculation. Likewise with the politicians who start the wars, IMO.
 
The Japanese must have at least suspected that we had broken the code.

WEB Griffon, in his THE CORPS series of WW11 fiction, has a character, a crypto-analyst, explain that there were undoubtedly low ranking officers and cryptographers who were aware that their code must have been compromised. However, according to the character, these underlings dared not bring this to the attention of their superiors for fear of being disloyal, or not respectful enough of Japanese "superiority."

One is reminded of Churchill's moral dilemma when the British Ultra program notified him of the German's intentions to bomb Coventry.
 
I'm not an ardent WWII enthusiast and have little interest in most of it, but the Yamamoto ambush was intriguing. I read about it some time ago and recall few details, but it seems there were around eight (?) planes with two extras and the chance of actually intercepting the Yamamoto party was a very slim one. There was some controversy over which pilot(s) actually did the deed and the controversy went on for decades. Perhaps it was never resolved; I didn't follow up.
 
The P38 was an outstanding plane. Hang a couple drop tanks on them and it was indeed a fine long range weapon. When flying over water 2 engines are much better than 1.
 
Ian Toll has a trilogy, War in the Pacific, this is covered in the second book.
I enjoyed these books very much, well written history. If interested, you might too.

Rex Barber was from Oregon and attended our local college, so you still hear about the story around here.

There was a dispute over credit for the Yamamoto kill, and at one point the Air Force officially split the credit between Barber and another pilot, named Thomas Lanphier.

But Barber's local champions wouldn't let it rest, and after another inquiry by state historians around 2000 or so the governor and state legislature officially took Barber's side. The Air Force didn't budge, though.
 
Admiral Yamamoto and the senior staff naval officers were obsessed about eliminating US battleships and aircraft carriers in the December 7 attack. The aircraft carriers were at sea.

The attack planners completely overlooked the drydocks and fuel tank farm across the harbor from the Battleship row. If the drydocks had been damaged or destroyed, ship repairs would have been delayed for weeks or months. If the large fuel tanks, visible in many of the Pearl Harbor attack videos, had been destroyed, the Pacific fleet was out of avgas and bunker fuel until more was shipped from the East coast. It is likely that 1 bomb into 1 tank would have created a fireball that destroyed the entire facility.

The Admiral was correct, a sleeping giant has awakened.
 
I use the story of Yamamoto's death to teach new analysts what intel can and cannot do.

Had anything changed or gone slightly wrong for either side, the intercept wouldn't have happened. I don't remember how far the P-38s flew to get there, but they had to time it to within a minute or two of when the Admiral's plane was supposed to arrive. Any navigation error or encounter with unfavorable weather by either side would have thrown the arrival time off and likely have caused the mission to fail.

Intel told them when and where to be, but it was still the fighter pilots that got the mission done.
