Chapter 20 1.3 Covert Attempts and Deception Strategies

The reason why we were able to attack the U.S. unpreparedly and achieve complete success in the surprise attack operation is that our navy, in order to ensure the victory in the Hawaiian operation, kept its secrets, concealed its own intentions, and then adopted deception strategies without fail, causing the enemy to make mistakes in judgment. , which should not be ignored. As Commander-in-Chief Yamamoto himself admitted, the battle in Hawaii started at the beginning of the war, using powerful air forces to break into the enemy's camp, just like Babuzama , Oda Nobunaga had a surprise attack here and killed Imakawa Yoshimoto.), Bulgotsu (Note: Refers to the mountain road from the north of Kobe City across the Rokko Mountains to the northwest in Hyogo County. In 1184, Minamoto Yoshitsune was preparing to attack Fukuhara's Hirashi, With Washio Saburo as the forerunner Zeng He overcame this difficulty.), Kawanakajima (Note: In the northeast of Sagaki-gun, Nagano Prefecture, the father of Saikawa. Takeda Shingen and Uesugi Kenshin have fought here several times since 1553. ) three campaigns combined into one (it is tantamount to a big gamble), its success is not easy.For this reason, it goes without saying that it took a long and tortuous process to align with the overall combat guidance of the military command.

One of the biggest reasons why the military command has been reluctant to make a decision on the adoption of the Hawaiian operation plan is that the key to the success of this operation lies in the concealment of the intention.And they judged: it must be very difficult to hide this attempt, and it is extremely speculative, and there is no guarantee of success.Once it fails, it will have a great impact on other operations. Not only the military command was anxious, but even the head of the First Air Force, who played the leading role in the attack on Pearl Harbor, was very worried about the success of this operation.

Chief of Staff Kusaka put forward his own opinion and asked Chief Yamamoto to reconsider the battle plan.Caolu said: When fighting in Hawaii, we seem to plunge into the chest of the enemy.In my opinion, the first battle of the Great War, which is related to the rise and fall of the country, should not be speculative and risky like this. However, the key to the success or failure of the Pacific War lies in whether the US Pacific Fleet can be wiped out.As long as this fleet is alive, it will not be able to capture the southern resource areas in the future, and it will also be impossible to establish and maintain our long-term invincible posture.If at the beginning of the war, we are lucky enough to give the U.S. fleet a big blow and stop its attack on the Western Pacific, then our army can safely fight in the south, occupy the key points of East Asia, and build a Greater East Asia Co-Prosperity Sphere.For this reason, instead of adopting the previous attack strategy of waiting for the US fleet to attack, it must be proactive. In the early stages of the war, it must attack the US Pacific Fleet on the Hawaiian side to make it lose its ability to attack the Western Pacific.This is the conclusion that Yamamoto Fifty-Six came to after repeatedly thinking about the battle plan. Therefore, the Hawaii battle can be said to be his unshakable belief.

On October 19, 1941, due to the alarm of Chief Nagano's military command, the Hawaiian operation, which had been stranded repeatedly, was finally included in the military command's combat plan as the United Fleet hoped. War is the biggest gamble, not to mention the attack on Pearl Harbor, even if it is called an unprecedented big gamble, it is not too much.However, since it is to be put into practice, it must be made successful. However, the absolute condition for the success of the attack on Pearl Harbor is to be unprepared, in other words, a surprise attack must be carried out.For this reason, we must not only strictly keep secrets and prevent the other party from knowing our intentions, but if possible, we must also take active measures to make the United States make a wrong judgment on our intentions.Regardless of the center and fleet of the Japanese Navy, the entire army was integrated in this way, using all the means that could be imagined in the mind, that is, the so-called doing everything to wait for the destiny.

What means were used? covert attempt to leave blank operational orders The Imperial Conference was held on November 5, 1941 (Note: According to the provisions of the Meiji Constitution, in the presence of the Emperor, the meeting held by important ministers and ministers to study major and urgent national issues is called the Imperial Conference).At the meeting, the "Imperial National Policy Implementation Essentials" was decided.This essential point is not a decision to go to war. It is said that as long as a compromise is reached in diplomatic negotiations with the United States, the war will be abandoned.However, the resolution, despite the conditions attached, was a de facto decision to go to war.

As soon as the imperial meeting ended, Nagano, the chief of the military command department, reported the navy's combat plan to the emperor and got approval.Yong Ye ordered one after another to prepare for combat. Sea Order No. 1 Showa sixteen years (1941) November 5th Nagano Shoshin, Chief of the Military Command, was ordered by the Commander of the Yamamoto Combined Fleet 1. The Empire has decided that for self-defense, war will be waged against the United States, Britain, and the Netherlands in early December, and all operational preparations must be completed. 2. The commander-in-chief of the Combined Fleet shall implement the necessary operational preparations.

3. All details are to be instructed by the Chief of the Military Command. Big Sea Finger No.1 Showa sixteen years (1941) November 5th Instructions from Commander-in-Chief Mizuno Shoshin to Combined Fleet Commander Yamamoto 1. The commander-in-chief of the Combined Fleet should prepare to launch war against the United States, Britain, and the Netherlands in early December, and send the required troops to the standby location before the start of the operation in time. 2. The commander-in-chief of the Combined Fleet should closely guard against sudden attacks by the US, British and Dutch forces. (abbreviated below)

The old constitution stipulated that the power of command belonged to the emperor. Therefore, the order of the sea was actually an order from the emperor to the navy, and at the end there was a detailed instruction for the head of the military command department.According to the instructions issued by the head of the military command department, it is Dahaizhi. On November 6, cadres of the Joint Fleet Command arrived in Tokyo from the flagship Nagato in Saiki Bay, Oita Prefecture on a plane dispatched by the Navy Center.The next day, November 7, in the First Conference Room of the Ministry of the Navy, the final study of the joint fleet combat order was made according to the No. 1 Dahai Order and No. 1 Dahaizhi.

Then he sent a telegram to summon the staff officers of each unit, and handed over the following orders to them on the 8th. (CLASSIFIED) Combined Fleet Order No. 1 Showa sixteen years (1941) November 5th Saiki Bay Flagship Nagato Combined Fleet Commander Commander Yamamoto Fifty-Six orders The operations of the United Fleet in the war against the United States, Britain, and the Netherlands shall be implemented in accordance with the appendix. Combined Fleet Order No. 2 contains the following description: Execute the first preparation for war: Dec. 8 is scheduled to be Y day This Y day is the approximate date of the start of the war.By the way, it is pointed out here that X Day is the day of war.

However, troops not directly related to the Hawaiian war were treated differently. In the appendix of "(Confidential) Joint Fleet Order No. 1" distributed, the content in italics below is blank. Chapter 3 First Stage Operations Section 1 Combat Policy 1. Fight against the U.S. fleet with advanced troops, mobile troops, and Nanyang troops. At the beginning of the war, the advance troops and mobile troops were used to surprise and annihilate the enemy forces, and prevent their counterattacks. If the US fleet escaped, try to capture and annihilate them. Section 5 Deployment of Troops Item 1 The main task column of the mobile troops deployed in the first phase of the first phase of combat troop deployment:

(1) Annihilation of the Hawaiian enemy fleet and combat essentials column (1) On X day, use all air force to attack and wipe out the enemy fleet in Hawaii. (2) Attack Midway Island with part of its forces and destroy its base facilities. (3) After the air strike is over, return to the mainland for maintenance and supplies. This discrimination is not only this time.When the Combined Fleet was conducting on-map exercises, the Hawaii operation was conducted as a special on-map exercise, and other than those directly concerned, they were not allowed to participate, and even visits were prohibited. Why does Combined Fleet Command give stepson treatment to all units other than specific units?This, so to speak, is the exact implementation of the principle: the first condition for secrecy is to keep the scope of notification to a minimum. So, when did the cadres of the United Fleet's First Air Squadron know about the Hawaiian combat plan?That was on October 7th.On this day, Chief Nagumo announced the plan to his commanders, staff officers, captains, flight captains, and flight captains, and only these cadres knew about it. At that time, the flying teams of the First Air Squadron were conducting intense training at Kagoshima, Izumi, Kasahara, Futaka, Saiki, Usa, Oita, Omura and other Kyushu air bases, and it was scheduled to be completed on November 15.In early November, the Hawaiian operational plan was communicated to the Flight Section officers. The mobile unit, which had finally completed the preparations, staggered the departure date and location of the ships of each team in order to conceal the attempt, and concentrated in twos and threes towards Danguan Bay.The aircraft carrier Kaga departed from Sasebo on the 17th, and the Akagi at 9:00 am on the 18th.The aircraft carriers Soryu and Hiryu of the Second Air Squadron disappeared from Saiki Bay at noon on the 18th, and the cruisers Tone and Chikuma disappeared from Saiki Bay at 2 pm on the 18th.The aircraft carriers Xianghe and Zuihe of the Fifth Air Force left Beppu at midnight on the 19th.On the evening of the 18th, the battleship Hiei, dispatched from Fangshan Tateyama Bay, rendezvoused with the Kirishima, which left Sasebo on the 17th, outside Tokyo Bay, and then headed north. During this voyage, the Hawaiian combat plan was issued to the ordinary crew.Up to this point, even the second in command of the aircraft carrier, Deputy Captain Zuo, has not been notified, which shows the strict secrecy. sneaky attack It is separated from Nemuro at the eastern end of Hokkaido by a strait, where Kunashir Island of the Thousand Islands lies horizontally. The largest island in the archipelago, Etoru Island, is just north of Kunashir Island, separated only by the Kunashir Waterway.There is a Danguan Bay on the south coast of the long and slender Iturup Island extending from northeast to southwest. There are two harbors in the bay, the outer one is called Nianmeng, and the inner one is called Tianning.Needless to say, those two ports are just small fishing ports in the desolate northern country. Fishing boats usually come and go here only during the fishing season, and almost no one knows their names. Winter in Qiandao comes earlier, as soon as November, it has already snowed.Only ships regularly in contact with Hokkaido occasionally come here to deliver food to the islanders.Other than that, no one goes at all.Covering the island is the tranquility, peace and snow of winter. In this desolate Danguan Bay, a major event happened suddenly that shocked all the islanders: the fleet sailed into the harbor!The number of one, two, and three ships is increasing.The children on the island climbed up the high slope and counted them. There were a total of thirty ships, large and small.Among them are battleships and aircraft carriers that have only been heard of but never seen. What's the matter? It must be a drill. While the islanders were discussing, the army of the mobile force was assembled. There were six aircraft carriers, two high-speed battleships, two large cruisers, one light cruiser, nine destroyers, three submarines, and seven oil supply ships.These thirty big warships gathered in Danguan Bay, a small port in Hancun, Northland, like Ako Magi (Note: Refers to the four who attacked Kira Yoshio's house on the night of January 30, 1703, to avenge his lord Asano Nagamo. Seventeen warriors.) Gathered upstairs of the small noodle shop, high-spirited and full of anger, wanting to annihilate the old enemy, the US fleet. No wonder the islanders were shocked when such a large fleet entered the port.It wasn't just this that shocked me.From November 20th when the fleet was about to sail into the port, all communication between Iturup Island and the rest of the island was cut off on the grounds of exercises.Needless to say, transportation with and outside the island, even all communications were stopped (this state lasted until the day of the war on December 8). Also, before the mobile force left the island, the ships and planes of the Ominato Garrison Office continued to patrol the surrounding area of ​​the island and the east sea. On November 26th, the mobile unit braved sporadic snowstorms to leave Danguan Bay and embark on an expedition.The target was the US Pacific Fleet at Pearl Harbor. Riding the wind and waves, heading east along the North Pacific waterway, needless to say, this route was carefully selected, avoiding the usual shipping lanes of merchant ships and avoiding the patrol circle of enemy aircraft. On October 22, the Combined Fleet assembled in Saiki Bay was trying to complete the last day of training. Commander Hanku Sasaki of the Third Submarine Squad received an order from the Commander of the Sixth Fleet: Commander Sasaki led the I22 submarine to quickly return to Wujun Port to implement the command project! Sasaki immediately came to the fleet headquarters and asked about the contents of the command project. The chief of staff replied: "We will implement a special secret project ordered by the minister."But the content is kept secret. The next day, the Yi-22 submarine sailed into Wujun Port and moored next to the factory's pier.Several technical officers came to the boat immediately and drew a few schematic diagrams of the rear deck, which seemed to be construction at the rear of the submarine. What project? The secret project of the Minister's order. It just misses the point. Submarine captain Yang Tianzhongzuo finally said: Commander, if I don't know the content of the project, I can't be responsible for the safety of the submarine as the captain. This statement is irrefutable.So Sasaki negotiated with the Fleet Command, and finally got permission to tell the purpose and content of the project only to the commander and the captain.This project is to carry a special submarine on the rear deck of the submarine. Once a war starts, the submarine must transport the special submarine to the enemy's base, let it leave the mother submarine, and go deep into the enemy's port to attack the enemy ship. At that time, this special submarine was manufactured in secret, and even in the Admiralty, only a few people knew about it.Also, for the sake of secrecy, this kind of submarine is called a special-type Gna tube, or simply a tube.Even Sasaki heard this title for the first time.It is naturally kept secret from the general occupants. In late October, crews on special submarines were granted a one-week vacation.Commander Colonel Harada said to them: No mention of work (attack on Pearl Harbor) should ever be mentioned in a sentence, anywhere, or to anyone.Also, you should act as usual as if nothing had happened, so that people don't feel that something big is going on secretly.You must arrange everything around you in an orderly manner, and return to the team without any worries.We must do our best to be filial to our parents, and we must see that this return to our hometown is a farewell to our parents.However, this impression cannot be given to parents.I only said that I will go to sea for training, and I may not be able to return home for a long time At that time, the letters of the ship's crew were also checked very hard, and the superior ordered not to write the location of the ship in the letter. The training order for day and night raids has also been completed.On November 6, the Yi22 submarine returned to Guigeshou on Cangqiao Island.There was no family near the place, and it was an unnoticed, deserted little port.Large cranes were already waiting there, along with barges carrying monsters covered in black cloth.As soon as the submarine arrived, the factory staff came to the boat and asked: All crew members, except the commander, captain and bridge watchman, are invited to the cabin. Then, the crane hoisted up the objects in the barge that resembled miniature submarines, and loaded them one by one onto the rear deck of Yi Er Er.This is the first time Sasaki has seen a special submarine. November 18, the day of the scheduled attack, finally arrived. Five mother submarines with special submarines on their back decks left the wharf of the Wu Naval Factory one after another and set out on a journey.No one saw them off, and it was exactly the same as usual driving out of the port to the fleet training ground for training.It was a beautiful day in late autumn, with a blue sky.The gray peak towering behind Kure City left people with a clear impression of deep affection, as if only this mountain was sending the special attack team off and wishing success. A gimmick to cover the radio waves of an attempt The best way for the United States to learn about the activities of the Japanese fleet is to rely on the complete equipment installed on the six islands of Oahu, Midway, Guam, and the Philippines to detect the radio waves of the Japanese Navy and determine the location of the source of the signal. Don't send out radio waves!As soon as the radio waves are sent out, our target is exposed! After the mobile troops set off from the mainland, they implemented radio wave warfare control, and the entire military ranks rushed forward without a sound.This is the strictest radio wave control, except for the urgent telegrams that are absolutely necessary for combat, all other radio waves are prohibited.The transmission of radio waves must be ordered by the supreme commander.Even so, I was afraid that if something went wrong, in order to completely block the radio waves, I even did not hesitate to remove the melting sheet of the radio wave circuit and the key circuit on the transmitter, bind the keys, and affix a seal. On the other hand, however, the exact opposite appears. Around November 15th, the flying teams of the First Aviation Squadron finally withdrew from the Kyushu base and returned to the mothership.The training units of the Reserve Air Force moved to empty bases to replace the aircraft of the 1st Air Force.The large fleet of more than 400 planes flying day and night suddenly disappeared. Even though we were careful to guard against spies, rumors and rumors would arise immediately, and the enemy's sensitive intelligence agencies would not sleep.Therefore, the original fighter base, flew fighter jets, and the original bomber base, flew bombers.At the various bases in Kyushu, the planes flew around in full swing as usual.In addition, the radio communication was also going back and forth between the joint fleet and the training force as usual, but in fact it was communication without content.The major changes in the various bases in Kyushu were subtly disguised in this way. Not only that, but the target ship Settsu was also specially sent to the Southwest Islands to send and receive simulated telegrams that the aircraft carrier force seemed to be operating in southern Kyushu. The U.S. side appears to have been completely duped and convinced by these tricks.For example: in the "Japanese Fleet Position Report" made by the U.S. Naval Intelligence Office in Washington on November 25 when our maneuver force set off from Danguan Bay, it was estimated that the aircraft carrier of the Japanese fleet was in southern Kyushu and near Kure Army Port. Taking Pearl Harbor as the target, the dumb mobile unit, which swung its guns to the east, finally crossed the international date line at 180 degrees east longitude at 00:00 on December 1, and was about to leave the eastern hemisphere and enter the western hemisphere.At this time, the radio call sign that the ship's force had just changed a month ago was changed.This call sign is usually changed every six months.This is like adding another gimmick to the radio gimmick. The gimmick of changing the call sign had an immediate effect.This effect is evident from the following reports from the US 14th Naval District (Hawaii) Communications Intelligence Office: December 1, 1941 All radio call signs of the Japanese Navy's maritime forces were changed at midnight this morning.Before then, it was changed every six months or more.The last change was November 1, 1941.This change of call sign after only one month appears to be a gradual introduction of large-scale positive action.Most of the radio communication two or three days before the call sign change was four or five days ago.The Japanese navy appears to be taking increasingly safe measures. December 2, 1941 There are hardly any reports today about Japanese aircraft carriers.One of the reasons for this lack of information is the lack of confirmation of the changed radio call signs.However, after the call sign change from December 1, some of the more than 200 call signs have been confirmed.Part of the call sign does not include the call sign of an aircraft carrier.Aircraft carriers have very little radio communication. Feint ship Tatsuta Maru After the imperial meeting decided to start war against the United States and Britain, on December 1, Commander Yamamoto issued the following order to the United Fleet: Climb a new mountain!1208 (Decided to start the war on December 8th. Act according to the scheduled plan!) The next day, December 2, the NYK ship Tatsuta Maru left Yokohama Port in the name of the second evacuation ship and headed for Los Angeles on the west coast of the United States. On this day, the "Asahi Shimbun" Evening News reported on the headline that Tatsuta Maru set off for the second time in the United States, braving the turbulent waves of the Pacific Ocean, saying: Among the 148 passengers, there were 35 foreigners, including the wife of the Norwegian Chargé d’Affaires in Japan, Consta, and a group of four including the Chilean journalist Branett. They came to Japan this spring. I have visited Manchuria and North China, and among the more than 60 overseas compatriots eager to return to the United States issued re-entry visas by the US government on the 29th of last month, only three have completed the procedures.Nanguo Taro, an old man who lived in the United States for fifty-four years, rushed to the ship just before sailing. Although the number of passengers was small, at the moment when the Japan-U.S. negotiations were at their most critical moment, the whole wharf was crowded with people who were seeing off Tatsuta Maru, who was about to set sail in the stormy Pacific Ocean.In the sound of "Patriotic March" played on the deck, people shouted goodbye, goodbye, waved their handkerchiefs one after another, and the boat left the trestle bridge. For Tatsutamaru's captain, Kimurahei, there were a few things he couldn't figure out. One of them was the repeated postponement of the date of departure.Originally scheduled to depart in mid-November.Then it was changed to November 20th, and then it was pushed back two days and three days until the 27th before it was decided to sail in December.Also, with regard to the ship's actions, the newspapers cite information released by the relevant authorities to exaggerate. "Asahi Shimbun" Evening Post on November 25: (Foreign Affairs Authorities) The imperial government is negotiating with the U.S. government to send a ship to the United States for the second time since it first sent a ship to the United States to evacuate overseas Chinese.Due to an understanding, it was decided to send Tatsuta Maru to Los Angeles and Balboa (Panama) this time.In addition, the ship will set sail as soon as it is ready, and it is generally scheduled to sail from Yokohama in the middle of this month. "Asahi Shimbun" Evening Post on November 27: (Released by the foreign affairs and mail delivery authorities) The decisions regarding the dispatch of the ship to the United States are as follows: Tatsuta Maru sails from Yokohama on December 2, arrives in Los Angeles on the 14th, departs from Los Angeles on the 16th, and departs from Los Angeles on the 20th. Arrived in Balboa in four days. Was Tatsuta Maru really for the purpose of evacuating Japanese expatriates?Why was the departure postponed again and again until December 2nd? Probably for more insurance.Four days after Tatsuta Maru left Yokohama, that is, on December 6th, the following news was published in the Tokyo evening papers: On the 5th of this month, the foreign affairs and letter delivery authorities issued a statement and decided to allow Tatsuta Maru, which sailed from Yokohama to Los Angeles and Panama on the 2nd of this month, to stop in Mexico halfway.The schedule is as follows: Arrive in Los Angeles on December 14 and set sail on the 16th; Arrive in Manzanillo on the 19th and set sail on the 22nd; Arrive in Balboa on the 26th and set sail on the 28th. The foreign affairs authorities published in the newspapers, as well as the foreign affairs and letter delivery authorities, needless to say, were all instructed by the headquarters of the Navy Department.This trick has no other effect, it is just to reassure the United States that the day when Japan decides to go to war is still far away.This is tantamount to using Tatsuta Maru as a bait for a feint. The day before Tatsutamaru left for the United States, on December 1, Lieutenant Toshiichi Toshiichi, head of the Military Affairs Bureau of the Ministry of the Navy, called the captain Mucunhei to the Ministry of the Navy and said to him: "Captain, you will have to work hard this time. Please be careful on the way." . After speaking, he handed him a heavy rectangular wooden box, as if there was something metal in it. Omae did not say what was in the wooden box.In fact, this box is full of sixteen pistols, and even the order documents for using the pistols are in the box. Why did Omae give sixteen pistols to the captain? That's because there were more than a dozen American military passengers on board the Tatsuta Maru.As soon as the battle broke out, the ship would turn back and sail back to Japan.If more than a dozen American soldiers find out about this, they will threaten the captain and ask him to steer the ship towards the United States. The next day, December 2, when the ship was about to leave the shore, Dazuo Lin of the Ministry of the Navy came to the ship and had a private conversation with Captain Kimura and Chief Bursar Kato in the chart room under the bridge of the ship.At that time, Lin Dazuo conveyed to them the strict order of his superiors: In order to prevent passengers from hearing the broadcast, the vacuum tube must be dismantled, and the cruise ship is not allowed to send any wireless telegrams to the outside world. The sailing bell rang all over the ship.Lin Dazuo, who hurried down the gangway, watched the huge Tatsuta Maru slowly leave the pier, and silently wished it a safe return after completing its mission. The fateful day of December 8 finally arrived. As soon as the battle broke out, when the temporary cabinet meeting was held at the prime minister’s residence in Mizutamachi, Tokyo, Tatsuta Maru followed the instructions of the Ministry of the Navy and slowly drove eastward outside the reconnaissance circle of the US military patrol plane (based on the island) north of Midway Island. Just after 10:00 a.m. local time on the 7th (7:00 a.m. Tokyo time on the 8th), the radio director of Tatsuta Maru panicked and called the Chief of General Affairs Sho Kato and said: Report to the Bursar, received a big news.The base camp issued an announcement.At dawn on the 8th, the Imperial Army and Navy entered a state of battle with the US and British forces in the Western Pacific.Again: Imperial Army and Navy Kato was taken aback, and immediately got in touch with the three government commissioners on board (foreign affairs, navy, and one from each of the three provinces for letter delivery), and immediately discussed how the ship should act. As a result, it was decided that Tatsuta Maru would immediately turn back and drive back quickly. Japan. Kato notified the captain of the decision.Because there was no order from the Ministry of the Navy, the captain hesitated at first, but finally made up his mind and turned back to return.The engine on the ship picked up speed all of a sudden.Just then, the Ministry of the Navy sent a telegram order: Tatsuta Maru will return immediately and return to Japan at full speed! Captain Kimura's responsibility is great.If the fact of the war ever got out and it became known that the ship was now sailing in the opposite direction, foreign passengers would boo and some might even take counteraction.We must do everything possible to avoid such things from happening, maintain order on board, and safely complete the tasks assigned by our superiors. Therefore, only a few cadres on the ship knew about the start of the war, not even the crew, let alone the passengers.However, the fact that Tatsuta Maru, which had been sailing eastward slowly, suddenly changed direction and headed west at full speed, this fact cannot be concealed from the experienced passengers. The boat is going in the opposite direction now!One of the passengers, an Italian lieutenant commander, cried out. Strange!This ship is not heading for the destination of the United States, but heading for Yokohama There was an uproar among the passengers.All of a sudden there was chaos on board.However, due to Captain Kimura, General Manager Kato and others coping well, the turmoil was quelled without using the gift given to the captain by the former lieutenant officer of the Navy on the eve of sailing.The booing of the passengers, fortunately, did not cause a major disturbance. In this way, Tatsuta Maru successfully achieved the purpose of the feint operation planned by the Admiralty of the headquarters, and returned safely to Yokohama on December 14.Whether the U.S. side was fooled by the move is unclear. Sailors Tour Tokyo On the morning of December 5, when the Cabinet meeting approved the U.S. ultimatum passed by the headquarters and the joint government meeting, about 500 students from the Yokosuka Naval Torpedo School got off the platform on the Tokyo Station Yokosuka Line platform. The hat hoops of the Navy Torpedo School on these sailor hats were replaced with hat hoops with the characters of the Imperial Japanese Navy.Led by their instructor, Lieutenant Masayoshi Iwashige, they lined up to the front of the palace. Here, about 500 cadets of the Naval Artillery Technical School wearing the same caps led by the instructor Lieutenant Minzang gathered together, visited the Imperial Palace on the square in front of the Double Bridge, and then left according to their own routes .Students from the Torpedo School visited Meiji Shrine and Yasukuni Shrine, and then visited the Asahi Shimbun headquarters near Yurakucho Station. In the afternoon, the students who were allowed to move freely, with their mouths open, wandered curiously in the center of Tokyo, Ginza during the daytime.The sidewalks of Ginza were suddenly crowded with sailors, their brightly colored blue uniforms and white leggings, very eye-catching. The activities of sailors visiting Tokyo lasted for three days from this day.Participants in this event were cadets and marines from various naval schools in Yokosuka, with a total number of about 3,000. After seeing such a scene, people described various feelings.Some frowned and said: The situation is so tense, and you still visit Tokyo, what's the matter?It's too carefree!Some admired and said: It really deserves to be the Japanese navy, how calm and unhurried it is! But there is another real purpose in playing this humorous tactic, and that is that in order to deceive the enemy, one must first deceive oneself. The Admiralty of the Headquarters instructed the naval schools and the Marine Corps in Yokosuka to arrange a large number of sailors to visit Tokyo as a means to keep the secret of the mobile force attacking Hawaii.The intelligence agencies of the United States, Britain and other countries are desperately spying on when Japan will launch a war. Under such circumstances, sailors visiting Tokyo seem to be a good way to conceal their determination to go to war. From this point of view, including the visit to the newspaper office in the plan of visiting Tokyo is undoubtedly an arrangement based on the desire of the headquarters of the Navy Department to report on the newspaper.This expectation was fulfilled.The "Asahi Shimbun" evening paper on December 7 published the news under the headline "Three thousand sea warriors came to the office", and published photos of the sailors visiting the newspaper office. According to the news, about 3,000 sea warriors who persisted in training day and night in the ever-changing and turbulent Pacific Ocean, led by two captains Jing and Iwashige, arrived in Tokyo in batches on the morning of the 5th, and lined up neatly for the second day. Shigehashi paid homage to the Imperial Palace, Meiji Shrine and Yasukuni Shrine, and then came to the shrine at 10:00 am. The sailors listened to the welcome speech by Hideo Nomura, the editorial director, in the auditorium on the seventh floor, and then visited the newspaper office for an hour.The sailors looked at the high-speed rotary printing press with amazement, watched carrier pigeons on the roof, and visited the Hibiya Broadcasting Hall.Afternoon free at leisure.After a fun day, return to camp in the evening. In addition, the morning issue of "Yomiuri Shimbun" on December 8 published a photo of the sailors surrounded by innocent and lovely children in the flower garden of Hibiya Park, and published a message saying: The wind is beautiful, the sky is as clear as washing, and the sun is shining. It is bright, so that people don't feel a little bit of early winter. This is the seventh day, a warm and warm Sunday, just like the fuel-saving slogan that warming up with a fire is worse than basking in the sun, it is a typical good day for basking in the sun. This is a scene of Sun Hymn taken in Hibiya Park. Next to the sage with red flowers, the sailors are surrounded by innocent and lovely children sitting on the dry grass, and they are telling the story of the warship. The story of the sea is here At this moment, the heroic sailors guarding the Pacific also forgot about the raging sea, and returned to the beautiful childhood, gathering and playing happily.Warm sunshine on the lawn, the sun laughing in the blue sky overhead. These sailors who visited Tokyo probably never dreamed that at this time the mobile unit led by Commander Nagumo was attacking Pearl Harbor in the remote North Pacific Ocean.
