Chapter 18 Japan won the first quarter

1.1 The Unsung Heroes of the Hawaiian War Spy Agents at Pearl Harbor Secretary Morimura is born Once Japan and the United States go to war, they will first strike Pearl Harbor, the base of the US Pacific Fleet. In order to contain Japan's southward movement, US President Roosevelt ordered the Pacific Fleet to sail into Hawaii from the west coast of the United States as early as May 1940.And according to the development of the situation in the Far East, it has steadily strengthened its preparations for war.From a strategic point of view, this is tantamount to stabbing a dagger into Japan's chest.Therefore, in the event of a war breaking out under such circumstances, the flanks of our country's long and broad southern front will immediately be seriously threatened by the US fleet, and there is no certainty of victory in southern operations.The Hawaii operation is indispensable as a battle to ensure the implementation of the southern front operation.Moreover, considering the strength of the Japanese navy, if the timing of the early attack is missed, the chance of winning will be lost. This is the opinion of Chief Yamamoto.

For the Hawaiian campaign to be successful, numerous difficulties had to be overcome. One of the most worrisome issues is the climate.If seven days of the month could be used in combat, the chances of success were not insignificant.There were also problems such as: the formation and training of a powerful carrier task force to participate in the attack; aviation torpedoes to attack warships anchored in shallow waters; the selection of routes for the attack on Hawaii; refueling of ships at sea; etc. However, the key factor that will determine the success of the Hawaiian operation is whether the main force of the US Pacific Fleet that is the target of the attack is actually anchored at Pearl Harbor.

Even if the Japanese mobile force is not detected by the opponent during the attack, and the weather conditions are good, the attack aircraft fleet will drive straight to Oahu Island. If the Pacific Fleet, the target of the attack, leaves the port for exercises or training, and there is nothing in Pearl Harbor, then it will be how?From the beginning of the war, the Japanese Navy was about to take the first irreversible wrong step. Therefore, the Japanese Navy Command had long noticed the Japanese Consulate General in Honolulu. It is not that simple to entrust the consulate general to collect the military intelligence needed by the military command.

The Military Command knew that it was certainly inappropriate for officials of the Ministry of Foreign Affairs to do jobs that were not their own. Moreover, this kind of work was very dangerous, and they would definitely feel embarrassed.Therefore, the Ministry of Military Command considered that it was necessary to deploy a naval officer as a full-time intelligence officer anyway, and secretly obtained the consent of the Ministry of Foreign Affairs.That is to say, in order to continuously and accurately grasp the dynamics of the American fleet in Pearl Harbor and other military information, it is planned to send naval officers there as personnel of the Consulate General.

At that time, there was a reserve navy second lieutenant named Takeo Yoshikawa in the Intelligence Department of the Military Command.When he was appointed as a second lieutenant, he retired from active duty due to poor health after recovering from illness. On a certain day in May 1940, the U.S. Pacific Fleet commanded by Admiral Richardson, unconventional, received an order not to return to the U.S. coast, but to stay at Pearl Harbor.On the same day, General Yamaguchi, head of the Fifth Division of the Japanese Military Command, told Yoshikawa: Yoshikawa-kun, I'm going to send you to Hawaii, what do you think?

Yoshikawa was puzzled and didn't know what to do. He thought that it might be a job like a messenger, so he just went to contact him.He said, "Okay, I'll go." So, start learning about American ships today!We will contact the Ministry of Foreign Affairs in a few days and don't tell anyone about this matter, even parents and brothers. Yes, I see. A few days later, Yamaguchi called Yoshikawa again and ordered him to go to the Ministry of Foreign Affairs to receive instructions.Yamaguchi lowered his voice and said to him: Yoshikawa-kun, I want you to be a staff member of the Consulate General in Honolulu and live there for a while.Procedures are handled by the Ministry of Foreign Affairs.Do as directed!

Yoshikawa lowered his head and listened intently to Yamaguchi's orders. Oh yes, you're still bald.Keep your hair up!Well, six, seven, eight, nine Yamaguchi counted the months with his fingers. Half a year will do. In order to show his face, Yoshikawa went to work at the Ministry of Foreign Affairs.He was assigned to work in the investigation department.It was also stipulated that he would take an examination for secretary students in the near future.Yoshikawa is not very interested in the work of the Ministry of Foreign Affairs, so he concentrates on studying the military situation in the United States at the Military Command.When he thought of the greatness of the mission, he became more serious.

At the Ministry of Foreign Affairs, the director general told Yoshikawa to use an alias.He didn't think of a suitable name himself, so he named it Morimura Masa according to the director's suggestion.Because this name is neither easy to pronounce nor easy to remember for foreigners. Yoshikawa passed the clerk's examination without taking it, and his name was clearly registered in the staff directory of the Ministry of Foreign Affairs.From then on, Naval Lieutenant Takeo Yoshikawa became the official Foreign Affairs Secretary Sheng Morimura. As early as the beginning of 1941, Yoshikawa received instructions to take up the post at the Consulate General in Honolulu and started preparations.His preparations were not limited to military preparatory knowledge, and even Morimura's luggage was not allowed to be sloppy.Suits and shirts and other things that usually have a name on them must be cautious in case the alias is seen through and revealed.Reminiscent of Han Feizi's admonition that the embankment of a thousand miles collapsed in an ant's nest, Yoshikawa became more cautious.Needless to say, the initials T‧M were written on the suitcases.

In this way, the Secretary Morimura of the Consulate General in Honolulu finally came out.The next thing is to wait for the Nitta Maru sailing from Yokohama in mid-March.All kinds of preparatory work took about a year. Positive activities of swingers Morimura On March 20, 1941, the gong sounded to announce the departure of the ship.The huge hull of the Nitta Maru on which Yoshikawa was riding quietly left the Yokohama pier. One morning a week later, Nitta Maru docked at the Honolulu pier.Several consulate personnel came to greet him.Needless to say, Yoshikawa met them for the first time.They don't know the details of Morimura.

Are you from the consulate?My name is Morimura. welcome!welcome!Hard work all the way! Please take care of me! The car drove to the consulate general.Yoshikawa walked into the Consul General's office and made a courtesy call. I am the secretary of Morimura.Come and report. Morimura saluted.Consul General Kita Nagao blinked and asked him to sit down, smiling and whispering jokingly: Are you Yoshikawa?I know.The military command has taken care of it.I will try my best to help, so just let it go! Among the local Japanese, only the Consul General knew that Second Lieutenant Yoshikawa's alias, Secretary Morimura, was sent to Hawaii by the military command to do spy work.Kita's words, to Yoshikawa, are like reinforcements from thousands of troops.

It must live up to your expectations!Yoshikawa's eyebrows were full of determination. It turned out that the purpose of sending Yoshikawa this time was to use the coded telegram sent by the Consul General to the Ministry of Foreign Affairs to report the military information obtained by Yoshikawa to the Military Command through the Ministry of Foreign Affairs. At this time, based on his previous four years of work experience in the military command, Yoshikawa devoted his energy to collecting the most valuable military intelligence.The so-called important information is: the type and number of American ships parked at Pearl Harbor in different periods; the types and numbers of aircraft deployed at the air base in Hawaii, the dynamics of ships based on Pearl Harbor, the air defense situation, and the patrols of aircraft and ships. conditions, security measures for ships and military installations, etc. Yoshikawa carefully considered how to obtain this information.He does not rely on external forces, but relies on his own strength to do it.Accuracy is an absolute condition for intelligence related to the destiny of a country.Therefore, seeing with your own eyes, listening with your own ears, and using your own brain to calmly judge, this is the most reliable method, and this is the path you should take.Fortunately, Yoshikawa is a diplomat, and there are many Japanese living in Hawaii.These are extremely beneficial to his intelligence-gathering activities. As soon as Yoshikawa took office, he started his activities.He was wearing green suit pants, a Hawaiian shirt, and a Hawaiian hat with feathers on his head. He hired a taxi for a ride in the name of sightseeing.He inspected Pearl Harbor, the base of the U.S. Pacific Fleet, and Hickam Field Airport, and other important military locations, and began preparations for future work.He thought of the map on the desk of the military headquarters, which he had carefully looked at almost every day. Now that these military targets were vividly displayed in front of him, an indescribable feeling arose spontaneously. Viewed from the hill, Pearl Harbor is like a huge sea car, shining white light.Under the blue sky with bright sunshine and summer-like seasons, warships of the US Pacific Fleet, large and small, are lined up on the blue sea like beautiful pastries coated with a layer of white cream.This scene has simply become a place of interest in Hawaii. Since then, Yoshikawa has passed by Pearl Harbor about once every four days to observe the situation in the harbor carefully.He spent a few minutes each time, accumulating over time, and meticulously recorded the types and numbers of ships moored in the port every day, using symbols that no one could understand except himself, and recorded them one by one in the black notebook. It was also at this time that in chartered cars or tour buses driving past Pearl Harbor, Yoshikawa often wore bright Hawaiian shirts, chatted and laughed happily with his maid, a nineteen-year-old beautiful Japanese girl.Because, for the young men and women who have trysts, the FBI monitors them more loosely. Just like that, the black notebook was filled with his precious handwriting page by page.However, Yoshikawa tried his best to hide this small book.Although the safe in the consulate general is safe, it cannot be used at night.It is dangerous to carry it on the body, so I have to hide it at home.But Yoshikawa is often not at home, so he may be searched at any time.He racked his brains to find ways to hide under the rug, in the back of a suit cabinet drawer, in a vase, and in the kitchen bin. One day, Consul General Kita came to Yoshikawa and said: Is it a bit boring to visit every day?Let me take you to a good place today.The place they went to was a Japanese tavern called Harushiro, located on the hills of the Aleva Heights. Coincidentally, the hostess of this tavern is from the same town as Yoshikawa, and is also from Matsuyama.Yoshikawa found that the entire Pearl Harbor can be overlooked from the second floor of the tavern. Since then, he has spent all day in Chunchao Building.Morimura, a swinger, and Japanese geisha, such as Xiang Jie, who had studied in Shimbashi, Tokyo, began to fool around.He often pretended to be drunk, hid behind the sliding window, and kept his eyes on the movement of Pearl Harbor. secret letter twisted into paper With the Japanese army stationed in southern French Indochina as a turning point, in August, the situation between Japan and the United States suddenly became dangerous. The FBI's surveillance of Japanese nationals living in Hawaii has also become more intense.Despite this, Tokyo still issued a secret order to step up intelligence gathering. Before long, Yoshikawa had a grimy face and disheveled hair, and Joe, dressed as a Filipino in a plain Hawaiian shirt, went to work in the sugar cane fields. From the sugarcane fields, Pearl Harbor is just around the corner.Later, Yoshikawa appeared here frequently.As time went by, his black notebook recorded the number of US ships parked in Hawaii in the order of Monday, Tuesday, Wednesday, Thursday, and Friday, and the statistics were gradually improved. In September, Yoshikawa can be seen fishing with a pole on the east coast.A towel was carelessly wrapped around his head, and a bored expression appeared on his face.At times, his fishing rod even ventured as far as Pearl Harbor. Yoshikawa was also concentrating on investigating military-critical coastal water obstacles, currents, and beach slopes at the time.His proficiency in swimming played a big role.Yoshikawa has been fond of swimming since he was a child.When I was in the fifth and sixth grades of elementary school, I swam with the young people in the village. I once won the championship in the near-swimming and long-distance swimming competitions, and I was like a dragon in the water. However, after a long period of twists and turns in order to coordinate the Hawaiian operation plan proposed by Commander-in-Chief of the Combined Fleet Commander Yamamoto with the general operational policy of the Military Command, Nagano, the Commander-in-Chief of the Military Command, finally made the following statement on October 19: Since Commander Yamamoto is so confident, as the head of the military command, I should take responsibility and do what you want.In this way, it was decided to use Nozomi Yamamoto's troops in the delayed Hawaiian operation, which was included in the military command's operational plan. Four days later, on October 23, the passenger ship Tatsuta Maru, which evacuated the last batch of civilians, sailed into Honolulu Port. On this ship was Minato Nakajima, a member of Section 5 of the Military Command (responsible for US intelligence) dressed as a passenger ship clerk. Major. On this day, Consul General Kita called Yoshikawa. Morimura-kun, do you know Major Nakajima? We know each other and worked together in the military command. To tell you, he has come.Do you think you want to meet? It is better not to see.I'm afraid there will be stalkers or bugs yes!Then I'll go to the ship to ask about the situation now. Kita, who came back from the boat, gave Yoshikawa something he said was from Nakajima, but it turned out to be a piece of Japanese paper. Twisting the paper carefully, I saw that it was densely written with small pencil characters.Here are ninety-seven questions for Yoshikawa.Nakajima asked Kita Zhuan Yoshikawa to answer the question in this paper before sailing tomorrow. The paper asked him to answer the following questions based on what he had learned in the past: 1.The total number of berthed ships. 2.Numbers and names of ships of different types. 3.Parking positions for battleships and aircraft carriers. 4.Berthing or mooring of battleships. 5.Dynamics of battleships and aircraft carriers (in and out of port, etc.). 6.The time it takes a battleship to get from its berth to out of port. 7.What day of the week do you infer that the most ships are parked? 8.Are battleships fitted with lightning protection nets when they are moored? 9.The number of days and location of the battleship docking. 10.Guidian claims that the battleships are kept in parallel. Is this a special case or is it often the case? 11.Are there large aircraft patrolling at dawn and dusk?If so, how many were dispatched? 12.Air bases and permanent troops in the Hawaiian Islands. 13.When an aircraft carrier enters or leaves a port, does the carrier-based aircraft take off outside the port? 14.The number of aircraft on Ford Island. 15.Are there any clogged balloons near Pearl Harbor? 16.Besides Pearl Harbor, are there any fleet anchorages? 17.Is there any precedent for temporary mooring in the Lahaina channel? 18.How often do sailors go ashore? 19.Are there signs of an increase in the Army's defense forces? 20.Construction status of underground fuel storage. 21.There are many oil tanks on the ground near the port. Is there oil in them? 22.The fleet is often dispatched, where to go?what direction?What are you doing? 23.If there are abnormal signs of shipboard fuel and food, report it immediately. 24.Where is the likely location for landing in front of the enemy? 25.Report the activities of the submarine as much as possible. 26.Is there an anti-submarine net at the mouth of the bay?If so, please report the details promptly. 27.Aircraft strengthening towards Kiska, Dutch Harbor and the Central Pacific. 28.Anti-espionage anomalies, and so on. That night, Yoshikawa spent a whole night answering ninety-seven questions based on the intelligence data he painstakingly collected over the past seven months.Here are some important questions: Question: What day of the week do you infer that the most ships are parked? Answer: Sunday. (Original author's note: The start of the war is December 7th, Sunday, Hawaii time.) Q: Are there large aircraft patrolling at dawn and dusk?If so, how many were dispatched? Answer: Both dawn and dusk are crosses. (Original author's note: Yoshikawa expected such questions. In order to see the patrol airship's departure and return with his own eyes, he stood on the lawn of the consulate many times at dawn and dusk to observe.) Q: Is there an anti-submarine net at the mouth of the bay?If so, please report the details promptly. Answer: Probably.But the species and others are unknown. (Original author’s note: When the war started, an anti-submarine net was installed at the entrance of the Pearl Harbor waterway. Yoshikawa considered this information in advance to be very important, and he had repeatedly sneaked into the bay wearing crumpled Hawaiian shirts and pretending to be Filipino workers .but never quite got there.) The next morning, Yoshikawa handed over the answer sheet to Consul General Kita.Xita wrapped it around her waist, patted her belly with her hands and said with a smile: "I will definitely hand it over to you!" Don't feel lost At that time, the Tojo cabinet was running wildly along the road of war, and the military command also made a concerted effort to make the last desperate effort to prepare for the war. From the ninety-seven questions mentioned above, Yoshikawa clearly saw the scales and claws of this domestic situation. Not long after Yoshikawa answered the ninety-seven questions, the mobile units of the Japanese Navy, which were tasked with attacking Pearl Harbor, quietly assembled before November 22, when Ambassador Nomura and Secretary of State Hull were having a heated discussion. Choose the Danguan Bay on the island.Four days later, that is, on the 26th, Hull's reply to the note actually broke the relationship between Japan and the United States. Deciding when to start the war is the most important issue.It is necessary to choose the time when the Pearl Harbor ships gather the most to deal a fatal blow to the US fleet. Telegram dated December 2 from Tokyo, instructing the Consul General of Hawaii that in view of the present situation it is extremely important for battleships, aircraft carriers and cruisers to berth at Pearl Harbor.Therefore, in the future, I hope that these situations will be reported every day as much as possible.Telegraph if there is any observation balloon over Pearl Harbor, or if there is any sign of an observation balloon being launched.In addition, it is also expected to inform whether the battleship is equipped with lightning protection nets. Originally, during the period when Yoshikawa first arrived in Hawaii, he was required to report once a week.Once August passed, it became a report every three days.This time I finally have to report once a day.Of course, Tokyo did not inform Yoshikawa of its intentions. However, the increase in the number of such requests for reports was enough to suggest that the time for war was imminent, and the target of the attack was Pearl Harbor. Yoshikawa noticed the anxiety of the military command from this instruction, so he drove, fished, and went to Chunchao Tower to have fun more frequently than before. On December 2, when the instructions for the daily report were sent to Hawaii, Admiral Yamamoto, Commander of the Combined Fleet, sent an cryptic telegram to the Mobile Force, which had already attacked from Danguan Bay and was advancing towards Pearl Harbor.This is the order to go to war.Day X, when the whole army was ordered to start the offensive, was fixed at midnight on December 8th.00:00 am on December 8th, Tokyo time, and 4:30 am on December 7th (Sunday), Hawaii time.As mentioned above, Yoshikawa, based on carefully accumulated statistical data, pointed out in answering the previous 97 questions that the day when most ships called at Pearl Harbor was on Sunday. It was a peaceful Saturday in Honolulu on December 6th, neither the roar of planes from Pearl Harbor nor any other sound could be heard.Yoshikawa finished his morning reconnaissance and made a report to Tokyo. He had lunch very late, and then dragged his tired body to lie on the bed in the dormitory.After sleeping for a while, I jumped up all of a sudden, and went to scout the situation of Pearl Harbor at dusk.The ships of the U.S. Pacific Fleet under Commander Kimmel were quietly floating on the summer-like sea all the year round. Huh?Why are the two aircraft carriers and ten heavy cruisers missing!I saw with my own eyes this morning that it was indeed parked there.How strange!Yoshikawa muttered, unable to believe his eyes. Yoshikawa hurried back to the consulate after dinner at the Chunchao Building, and immediately started drafting a telegram to send to Tokyo.Yoshikawa drafted Consul General Kita's Urgent Telegram No. 254 to the Minister of Foreign Affairs, which reported the situation at Pearl Harbor as follows. This telegram was sent about twelve hours before the Mobile Force began its attack on Pearl Harbor.But Yoshikawa had no way of knowing that this was the last report. The following ships were moored at Pearl Harbor on the 6th: nine battleships, three light cruisers, three submarine carriers, and seventeen destroyers.In addition, Light Cruiser 4 and Destroyer 2 have been docked.Aircraft carriers and heavy cruisers have all left the port and are not berthing in the port.There was no sign of aerial reconnaissance by the Fleet Air Force. According to this report, the Admiralty, the headquarter of Tokyo, conveyed the following information to the attacking Pearl Harbor force: At 6:00 pm (Tokyo time) on the 7th: 1. A Information (Key Points) On the 6th local time, ships were moored: 9 battleships, 3 light cruisers, 3 submarine carriers, and 17 destroyers.The docked ones are: Light Cruiser 4 and Destroyer 2.Aircraft carriers and heavy cruisers have all been dispatched.The fleet is unremarkable. 2. The headquarters of the Admiralty is sure of victory Behind the confidence of the Admiralty of the base camp that it will win, Yoshikawa's precious report cannot be ignored. Before he sent the above-mentioned telegram "Mooring Ships in Pearl Harbor", he sent the following telegram and put forward his own opinion at the same time: (1) At present, there is no sign of deploying blocking balloon equipment.Also, it's hard to imagine how much of this equipment they actually have.However, in order to control the sea surface and the vicinity of Pearl Harbor, as well as Hickam, Ford Island, and the air above the land runway of Ewa Airport, even if such preparations are actually carried out, the use of balloons to defend Pearl Harbor is limited.I think a surprise attack on these locations is a surefire success. (2) I don't think torpedo defense nets are installed on battleships The timely and accurate A-information issued by the Admiralty of the base camp based on the information collected by Yoshikawa painstakingly, needless to say, made a huge contribution to the success of the Hawaiian operation.The following records and recollections clearly prove this point. Greater East Asia War Training (Yokosuka Naval Air Force): In our opinion, obtaining the desired accurate and reliable information at the necessary time and knowing the situation of the US fleet and the enemy on Oahu is a good example for future wars. 5th Air Force battle report: The intelligence of the central government is very accurate, and it is possible to know the situation of Oahu Island well. Memories of Chief of Staff Caolu of the First Aviation Team: Thanks to the huge and meticulous care of the military command, it was possible to keep abreast of the enemy's situation in Pearl Harbor. Yoshikawa's last report was the above-mentioned Telegram No. 254, and it was around 9 o'clock when the encryption of this telegram was completed.Even Yoshikawa, who was full of energy, felt fatigued from day to day.After he drank two or three glasses of whiskey in one breath, he went for a walk on the lawn in the courtyard of the consulate as usual before going to bed.The roar of the plane could not be heard in the air.It was a quiet weekend night, and the whole of Hawaii was no different from usual.Yoshikawa lay down calmly on the bed. Dawn is December 7th (December 8th, Tokyo time). Yoshikawa, who was exhausted from yesterday's heavy labor, had a long sleep in the morning. It was past seven thirty when I got up from the bed.Just as he was having breakfast, he suddenly heard a terrible, deafening sound, followed by explosions and gunfire It seems to be a large-scale exercise! Go outside and have a look!Yoshikawa ran outside and looked at the sky, only to see thick smoke billowing over Pearl Harbor, and the mark of the sun was clearly visible on the wings of the plane passing through the faint morning fog. Japanese planes!Fight!Yoshikawa hurried across the courtyard to the office building and reported to Consul General Kita.At this moment, Kita came out. Kita-san, let's fight! Um! The two looked up to the sky and expressed their solidarity with the Japanese aircraft.The Consul General tightly grasped Yoshikawa's right hand, tears filled his eyes Yoshikawa's eyes were full of uncontrollable tears, as if he felt that the tense heartstrings had been slowly relaxed up until this moment, and an indescribable emotion of mixed sorrow and joy welled up in his heart, making him feel at a loss. Embassies and Consulates in Panama and the West Coast of the United States When talking about the reasons for the success of the Hawaiian operation, we cannot ignore the contribution of our embassies and consulates abroad, especially the legations in Panama and the consulates on the west coast of the United States in providing military intelligence. These embassies and consulates abroad officially began to collect military intelligence according to a telegram sent by Tokyo to the Minister of Foreign Affairs of the embassy in the United States on February 15, 1941.The telegram is as follows: Telegram No. 073 For information concerning the United States and Canada, the following are especially required: 1. The strengthening of preparations for war in the Pacific and Hawaii regions, as well as the supply of military materials, the quantity and type of materials in stock, and the transfer airports of aircraft (the transportation of large passenger aircraft should also be carefully recorded). 2. The dynamics of ships and aircraft (especially the actions of large aircraft and seaplanes). 3. Whether the government has requisitioned merchant ships (if there is any change in the usual plan, it should also be recorded) and whether some modifications have been made to merchant ships. 4. Recruitment training (exercise summary) and dynamics of army and navy personnel. 5. The words and deeds of junior army and navy personnel. 6. Conscription status of different races, with particular attention to whether blacks are recruited.If so, what are the conditions? 7. The situation of the students entering the army, navy and aviation departments after graduation. 8. Whether there is any use of transport ships to send troops to the South Pacific.If so, it should be reported in detail. 9. The progress of the expansion of weapons and production institutions, the production capacity of aircraft, and the increase of workers. 10. The general situation of Alaska and the Aleutian Islands, especially the movement of aircraft in the area, and the emergency situation including the shipment of military supplies. 11. An overview of the US defense posture. 12. Communication with Central and South America and the South Pacific region (including air contact), and the transportation of military supplies to these regions. Copies of this telegram are to be forwarded as Ministerial Orders to New York, San Francisco, Los Angeles, Seattle, Portland (Chicago or New Orleans), Van Coover, Ottawa, and Honolulu.In addition, as a reference, I also hope to pass it on to Mexico and Panama (the US side deciphered this telegram on February 20). Embassies and Consulates in Panama The Panama Canal, which opened to traffic on August 15, 1914, is an important national defense strategy of the United States and a gateway connecting the Atlantic Ocean and the Pacific Ocean.Therefore, the location of the Japanese legation here is extremely beneficial for understanding the dynamics of American ships and ships.In other words, based on information such as ships passing through the Panama Canal, it is possible to accurately grasp the situation of the transfer of US maritime forces from the Atlantic to the Pacific. The statistics of the telegram reports deciphered by the United States and sent to Tokyo by the Japanese Legation in Panama, compiled by the Joint Committee of the U.S. Senate and House of Representatives in the "Pearl Harbor Attack Record" are as follows: 1941 Canal Navigation Status August: 2 September: Tuesday October: Thursday November: 8 Defense of the Canal Region august: a September: ○ October: Wednesday November: ○ total August: Wednesday September: Tuesday October: July November: 8 Take the November 15 telegram from Panama in the report as an example: No. 246 Report on Ship Navigation in the Panama Canal 1. On November 2, a 6,000-ton army transport ship loaded with soldiers sailed to the Pacific Ocean. 2. On November 4, two cruisers of the Omaha type moored at Balboa. The ships sailing to the Pacific Ocean on the 3rd, 4th and 5th include: one American cargo ship and one British cargo ship (1,400 tons).From the Pacific Ocean, there are: three American cargo ships, one American oil tanker, and one British cargo ship (20,000 tons). Consulate in the West Coast of the United States In the north, Seattle, the largest naval shipyard on the west coast of the United States, across Puget Sound, Portland, Oregon, has our consulate; in the middle, San Francisco, famous for shipbuilding, repair and supply, has our consulate; in the south , San Diego and Los Angeles near San Pietro Naval Port have our consulates. Since May 1940, in order to restrain Japan's southward advance, the US Pacific Fleet, which has been operating from the west coast of the United States, sailed into Pearl Harbor and stopped frequently.Since then, the facilities of Pearl Harbor, the forward base, have taken on a new look.However, due to reasons such as ship maintenance, supply and crew recuperation, the west coast of the United States is still indispensable to the Pacific Fleet. Therefore, the location of the Japanese consulates in the above-mentioned important military locations is the best for spying on the movements of the US fleet.The statistics of military intelligence telegrams from the Japanese Consulate on the west coast of the United States in 1941 recorded in the "Pearl Harbor Attack Record" deciphered by the United States are as follows: January Consulate General in San Francisco: 1 Consulate in Seattle: Six Consulate in Portland: ○ Consulate in Los Angeles: 5 February Consulate General in San Francisco: 3 Consulate in Seattle: Four Consulate in Portland: ○ Consulate General in Los Angeles: 2 March Consulate General in San Francisco: ○ Consulate in Seattle: Six Consulate in Portland: ○ Consulate General in Los Angeles: 2 April Consulate General in San Francisco: ○ Consulate in Seattle: Four Consulate in Portland: ○ Consulate General in Los Angeles: 2 May Consulate General in San Francisco: ○ Consulate in Seattle: ○ Consulate in Portland: 1 Consulate General in Los Angeles: 1 June Consulate General in San Francisco: ○ Consulate in Seattle: Three Consulate in Portland: Four Consulate in Los Angeles: ○ July Consulate General in San Francisco: 1 Consulate in Seattle: ○ Consulate in Portland: 1 Consulate in Los Angeles: ○ August Consulate General in San Francisco: 1 Consulate in Seattle: ○ Consulate in Portland: ○ Consulate in Los Angeles: ○ September Consulate General in San Francisco: ○ Consulate in Seattle: ○ Consulate in Portland: 2 Consulate in Los Angeles: ○ October Consulate General in San Francisco: ○ Consulate in Seattle: ○ Consulate in Portland: 2 Consulate in Los Angeles: ○ November Consulate General in San Francisco: ○ Consulate in Seattle: ○ Consulate in Portland: 1 Consulate in Los Angeles: ○
