April 18, 1943 was a Sunday, the weather was nice, the sun was shining, there were no clouds, it was a good day to fly. At 6 o'clock, Isoroku Yamamoto, commander of the Combined Fleet of the Japanese Navy, led the chief of staff and others to the airfield and took two "One" land-based bombers to the front line for inspection. The six Zero fighters were divided into two teams in a three-three formation, escorting yamamoto on the left and right sides of the plane.
At the same time, 18 U.S. P-38 Lightning fighters also took off from Guadalcanal.
In fact, Yamamoto's trip was strongly opposed by his subordinates, but Yamamoto, who had always been self-conscious, could not listen to the opinions of others at all, and insisted on going to the front line to comfort the soldiers and boost morale.
At 7:45, the two teams met. The 12 U.S. P-38s quickly climbed to an altitude of 6,000 meters and lured six Japanese Zero fighters into hot pursuit. At this time, another 6 P-38s of the US military swept at the Yamamoto landplane. In an instant, Yamamoto's landline dragged thick black smoke and fell into the dense forest.
In this regard, the death of a generation of tyrants marked the end of the Yamamoto era of the Combined Fleet of the Japanese Navy, and also announced the beginning of the doom of the Japanese Empire.
In fact, this was caused by U.S. intelligence officers intercepting and deciphering japanese codes. To talk about intelligence, we have to start with the Japanese attack on Pearl Harbor.
Before the Pearl Harbor exercise, the Japanese Navy sent a "placket" called an oil tanker that was actually a special agent ship, under the pretext of going to the west coast to buy oil and go to Pearl Harbor to spy on the military.
There were several unusual figures on board: The Japanese Military Command's communications and espionage expert, Fukamachi Shosa, the head of the Japanese Military Command's Intelligence Section on the United States, Ogawa Kansai Shosa, and more than a dozen junior officers who were proficient in espionage work. In addition, advanced radio monitoring devices have been installed on board.
From the beginning to the end of the exercise, the ship had been parked in the waters near Pearl Harbor, desperately listening to the radio waves from the United States and collecting a large amount of information, including the size of the exercise, the strength of the troops and the course of the exercise. It can be said that this reconnaissance has obtained important intelligence resources for the sneak attack on Pearl Harbor.
On November 26, 1941, a combined fleet of six aircraft carriers took advantage of the darkness to quietly sail toward Pearl Harbor, a small island in the Pacific Ocean. In just one hour, 45 ships of various types and more than 340 aircraft of the U.S. Pacific Fleet were destroyed or damaged, 4,500 soldiers were killed or injured, and only three aircraft carriers outside the harbor were spared from poisoning. It can be said that the US Pacific Fleet was almost completely destroyed. Since then, Yamamoto Isoroku's reputation has been greatly enhanced. The United States was forced to declare war on Japan.
After the Pearl Harbor incident, the U.S. Navy was painfully determined and gathered excellent intelligence personnel to decipher the Japanese Navy's so-called "Book of Heaven" cryptography system, JN-25b. The most prominent representative of them is Joseph Rochefort, known as the "Master of Magic".
Rochester graduated from polytechnic and entered the Navy after graduation. Rochefort grew up fascinated by mathematics and aspired to become a mathematician. After enlisting, because of his superhuman imagination and incredible associative power, he was transferred to the naval headquarters to study codebreaking. During this period, after three years of further study in the Department of Mathematics of the University of California, he served as a translator and telegrapher in the State Department's cryptography room. From 1929 to 1933, he was sent to the Japanese Embassy as an interpreter, focusing on Japanese codebreaking.
After Pearl Harbor, Rochefort became the head of the Hawaiian intelligence service. He picked a bunch of the best password and language geniuses. To this end, Rochefort and dozens of his intelligence personnel worked around the clock in the heavily guarded basement and intercepted 90 percent of the Japanese Navy's telecommunications.
The JN-25b is the Japanese Navy's "ship coding system", and there is nothing special about it, but it can't stand up to the Japanese's trick: upgrades. As soon as the code was upgraded, the previous painstaking deciphering work was abandoned, and I had to start over. Throughout the Pacific War, the Japanese code was upgraded as many as 12 times.
They worked day and night, day and night, still at a loss and with a headache. It was not until January 20, 1942, that the codebook was found from the sunken Japanese submarine "I-124". Four months later, 90 percent of the secret messages sent to and from Japanese people were translated correctly. As a result, important information such as the Japanese attack on Port Moresby and Midway Island was grasped by the U.S. army in advance, so that Yamamoto Fifty-Six was killed by the air!
Regrettably, rochefort was transferred back to Washington as a result of internal political struggles, and intelligence efforts were weakened. As a result, the failure to break the information on the evacuation of the Japanese from Guadalcanal in time led to the escape of nearly 10,000 Japanese troops and more than 800 navies. However, the Japanese, who have always been self-righteous and cunning and arrogant, did not think of their code being deciphered until their deaths.
Recently, in view of the collusion between the United States and Taiwan and pelosi's channeling of Taiwan, our army has organized various troops to carry out important military exercises in the Taiwan Strait area. In order to eavesdrop on and steal our important military intelligence, the US military has carried out thousands of reconnaissance planes from the Ryukyu Islands and Luzon Islands, and reconnaissance satellites have passed over the islands intensively, and even unidentified foreigners have tried to secretly film the military exercises of our People's Liberation Army on the spot.
Therefore, whether it is a traditional war or a modern war, intelligence warfare will run through the war and even affect the victory or defeat of the war.
