When the Japanese Empire was still very weak, in order to narrow the gap with Western countries, they did almost everything, and even did not hesitate to use special means to send a large number of spies abroad. For a while, almost one out of every three overseas Japanese was a Japanese spy.

Some of them were sent by the government, and some were spontaneous out of patriotism, and these Japanese were like sponges absorbing information, greedily searching for all the information they could get their hands on, whether it was military science and technology, industrial commerce, and commerce, and they would try to get their hands on any information that they thought might be useful to the Japanese Empire.

The Japanese are unusually generous in their intelligence-gathering work, whether it is money, fame or even the body of a Japanese woman, as long as they think it is necessary, they will not hesitate at all. At least 20% of the rapid rise of the Japanese Empire should be attributed to these supernumerary spies.

It is because they are good at using spies abroad that the Japanese are very sensitive to their own domestic intelligence information control, because they have always believed that they can detect Western intelligence, so Westerners will definitely do the same to Japan.

The Japanese military's secrecy and anti-espionage work has been quite meticulous, and in fact it has indeed achieved considerable success, and the closed environment of the island country itself is a natural barrier, and the differences in race make it even more difficult for Western spies to move an inch, and foreign spies have no chance to get in touch with Japan's core intelligence, which is also one of the reasons why Sorge is famous in history.

The secrecy of the Imperial Japanese Navy was second to none at the time, and compared to the carefulness of the Japanese, the historical Germany and Italy were simply two big colanders.

Since the end of the Taisho period, the Japanese Navy has begun to delete and revise the equipment data and data released to the outside world, and has strictly sealed the information on the development of new weapons, not only to guard against outsiders, but sometimes even to deceive its own people, so that many weapons and equipment data were not known to outsiders for the first time until the end of the war.

The most famous is the super super crossbow class battleship [Yamato], before the outbreak of the Pacific War, not many people in the outside world even knew about the existence of this warship, even after the US Navy sank it, all the intelligence data about this battleship is still from the naval intelligence department's speculation, and most of it turned out to be wrong later.

In the early days of the Pacific War, the intelligence postures of Japan and the United States were completely unequal, and it should be said that the United States was at a clear disadvantage, because Japan's strict domestic control system made American intelligence gathering often futile.

Therefore, Hanafang's unintentional gaffe is already a leak in the Japanese Navy, and if someone wants to deal with him, he can take this matter out and go online. Hua Fang realized his mistake, his face suddenly turned white, and he looked at Guidao with a worried expression, hoping that the boss would not notice.

Guidao is also a person who has served as a submarine captain, how could he not notice this, but it seems that he does not seem to care about Hanafang's gaffe, and still chats with the German captain as usual.

"Your ship looks like it's been cruising for a long time, is it ready to go back to Saigon Harbor?" Kishima dusted off his cigarette ash in an aluminum ashtray and probed the German captain at the same time.

Guidao didn't think that the captain of the Independence Nation was deliberately spying on the Japanese side just now, he felt that the other party was more like showing off the advanced technology of the Independence Submarine Ship.

It is true that the noise emitted by the submarine is much lighter than that of the Imperial Navy, and it is said that the diesel engine of the independent submarine uses a special means of damaging shock, but unfortunately the national country has always been reluctant to teach the Japanese experts the tricks. It would be nice to have a chance to enter the power compartment of the independent submarine and take a look, Guidao thought to himself.

In addition, what makes Guidao curious is how the submarine of the Independent Nations is equipped with ashtrays, and is it allowed for them to smoke in the submarine? Usually, the Japanese Navy only allows the crew to sail or anchor on the surface of the submarine, and only after obtaining the permission of the captain's rest law, they are allowed to smoke in the control tower and the front and rear decks, and all the toilets on the submarine are all open, which is the "B" rest law of the Japanese Navy submarine (at that time, there were three kinds of rest regulations on Japanese submarines, A, B and C, Law A is that no one is allowed to go on the deck except for the personnel on duty in the control tower, and Law C prohibits personnel from resting on the control tower and the toilet outside the boat is closed. ）。

Most of the sailors on the Japanese submarine are smokers, according to the Japanese Navy's order, each person can be allocated twenty cigarettes per day, which is exactly the amount of one pack, if it is a regular cruise, it is not much of a problem, once you enter the combat cruise, then it is all up to luck if you want to smoke, so few people can smoke the share. Not every sailor had the opportunity to go on deck, so he went to the conning tower to watch the lookout, which was often used by officers as a reward for good performance.

It seems that the regulations of the German Navy in this regard are somewhat different from those of Japan, although the Japanese and German navies have had some exchanges before, but this is the first time between the submarines of the two countries, because the German submarine force has not been taken seriously by the German military top brass, and the result has also affected the Japanese Navy's perception of this aspect of intelligence. Hitler was not very interested in submarine forces, and although he personally participated in several parades of submarine forces, it seems that the Führer preferred the big pipes on the huge ships.

"Yes, we've been out for twenty days and we're getting ready to return to base, but not in Saigon, but at Haiphong Port." Robin replied with a smile.

The Japanese should have been aware of the secret anchorage of a German submarine off the coast of Vietnam, and that some Japanese freighters with suspicious tracks were often watching off the coast of Vietnam in recent times. Of course, this anchorage can't be hidden for too long, and sooner or later it will be detected by Japanese spies, but at that time, U1001 should also return to Germany, and whether this anchorage is exposed or not by then has little to do with Robin and them.

The mechanical wear and tear of the U106 is not serious, and after this trip to Singapore for docking and maintenance, the submarine can be completely restored to the state it was in when it departed from Wilhelmshaven.

"Oh, we're from Kaohsiung Port, and we've only been at sea for three days." Guidao has a good time here, the Yi 60 actually sailed from Sasebo Port, but it had docked at Kaohsiung Port four days ago.

The Japanese Navy's large submarine was designed to build a large submarine with powerful firepower and long-range endurance. This was a remedy devised by the Imperial Japanese Navy in response to the weakening of the Japanese Navy by the Washington Naval Treaty, which did not impose restrictions on the number and tonnage of submarines, so the Japanese Navy tried to make up for the gap in the number of surface warships by building large submarines.

As a result, these loopholes were closed during the London Naval Treaty, and in the end, the Japanese were so squeezed out that they would not play with you shameless British ghosts.

The special background of the large submarine in the sea has made her have a very strong endurance and self-sustaining ability at the beginning of the design, she can sail 10,000 nautical miles continuously at a speed of ten knots, and at the same time, she can carry out a continuous mission for three months after a replenishment. So for the U106's twenty-day voyage, there is nothing to brag about in Guidao's opinion, but out of etiquette needs, he must compliment the other party, anyway, the people of the independent country will not take this seriously.

"Oh, it turned out to be from Kaohsiung." Robin reached out and pushed the snack plate on the table.

"Please try our German cream biscuits, which are flown in from Germany and are not usually available at sea."

"Oh, was it transported by plane from Berlin? This is a must-try. "Guijima was amazed.

It looked like an ordinary baked biscuit, and I don't know if it was actually flown in from Berlin, but Guijima didn't think it was bragging, so he carefully picked up a piece and put it in his mouth with an elegant gesture.

It tasted like a cream sandwich cookie, not much different from what you could buy in Asakusa, Tokyo, but to Kijima's surprise, it looked like it had been frozen, and the cream filled still had a chill in your mouth.

"Hmm." While munching on the biscuits, Kijima gave a thumbs up.

"My sister (delicious)," he said, turning to Hanafang.

"Heh, it's worthy of a single will, and I actually used a plane to transport this ordinary snack." Hanafang chewed the biscuit and nodded.

"Don't just look at the surface, since the independent country can transport this kind of snack by air over long distances, then of course they can also transport other supplies, which is the national strength of the European hegemon." Guijima admonished his subordinates in Japanese.

"Ha, I see, Commander." Hua Fang hurriedly bowed his head and was taught.

"Thank you very much for your hospitality, Captain Robin." Kijima pulled a handkerchief from his pants pocket and wiped the crumbs of biscuits from the corners of his mouth.

"Captain Robin, we have no problem with your request to exchange supplies, but I would like to ask you what kind of supplies you want to exchange." Having eaten and drunk, it is time to talk about "business".

"Anything, grain, vegetables, meat, canned food, cigarettes, drinks, alcohol, all of them." Robin replied happily.

"Can you provide a specific list, and how many people are you going to exchange?" This kind of thing is not without precedent before, it is a form of friendship between foreign sailors, but usually this kind of exchange takes place privately in the harbor docks, and it is the first time that such an exchange has been encountered on the island at sea.

The main reason is that there are few opportunities to encounter such calm sea conditions as today, the water surface stability of the submarine itself is insufficient, and it will sway seriously when it encounters wind and waves, and even if it is a normal sea surface supply, it often tires the crew half to death, and who would be interested in exchanging supplies with others.

"Let's change it for ten people, Mr. Lieutenant Colonel, I heard that you have only been on the voyage for three days, and you should still bring fresh vegetables." Robin asked, "We can exchange it for you in cans, the best German prosciutto." ”

Originally, it was just an excuse to come up with a pat on the head, but now it seems that this is better than a real deal, because it is located in the sea area of Southeast Asia, the temperature in the cabin is hot and humid, and the U106 does not carry too many fresh vegetables, and it has eaten all of them two days ago.

"We brought some turnips and dried vegetables." Guidao turned his head to look at the flower house.

Here I want to mention the food problem of the Japanese Navy, I am afraid everyone has heard this saying, the food standard of the old Imperial Japanese Navy was so high that in later generations there were Yamato Hotel, Musashi Hotel rumors circulating.

It is not an exaggeration to say that this statement is not much, and compared with the hard-working Japanese Army, the Navy does eat much richer. It should also be added that the meals of Japanese naval officers and junior soldiers were completely different, and could even be described as vastly different.

As we all know, the Japanese Navy has always taken the British Royal Navy as an example since the day it was founded, and the biggest feature of the British Royal Navy is the aristocratic cultivation of officers, so the daily meals of Japanese naval officers are all formulated according to the standards of the British Navy.

In fact, when the army was on the mainland, there was not much difference between the food and the navy, and the Japanese army soldiers could eat meat, vegetables, canned food, all kinds of fruits, coffee or tea, all kinds of desserts, sake and cigarettes every day. At that time, the average Japanese farmer's three meals a day were just brown rice with miso soup and a little pickled vegetables at most, and meat was a luxury that was only available during the Chinese New Year.

But after the outbreak of the Sino-Japanese War, the Japanese Army went to Chinese mainland, and supplies had to cross the ocean to be transported from the mainland to the battlefield. At the beginning, in order to reduce transportation costs, most of the Japanese army ordered the troops to requisition grain on the spot, and to put it bluntly, it was to grab it from the local Chinese people. At first, they were indeed able to "collect" some grain, but when the Chinese people's stock of grain was robbed, the "collection" on the spot became an empty letter. Moreover, in addition to staple food, a large number of non-staple food supplies still need to be procured from China and transported to the Chinese battlefield across the ocean.

The cost of replenishment for the Japanese army gradually increased with the extension of the battle line, so that the cost of the army was several times higher than that of the navy for the same cost of food, so of course it was impossible to continue to maintain the level of the domestic garrison.

The sailors on the Japanese Navy warships did not have the problem of supply loss at all, so every dime of their food expenses was spent on the purchase of food and materials, and the deployment of materials stationed in the local area was convenient, so until the end of the war, they could still maintain the standards before the war.

Of course, there are some unlucky, such as the island garrison unit under the navy, when the sea supply line was cut off by the US military, they suffered from the same hunger as the army on the island.

The submarine is a special ship in the Japanese Navy, because of the special conditions, the standard of food for the crew was set by the Ministry of the Navy alone, from Taisho to Showa 15, the standard has been changed three times.

Because the internal environment of the submarine is special, it is often in a state of high temperature and humidity, and at the same time, the air pressure in the cabin changes greatly during submarine, and the cooking conditions are also harsh, which are very different from surface ships.

For example, in the case of rice, the staple food of Japanese sailors, the submarine must be equipped with hard rice that is not easy to get wet, and the inner layer of the rice bag must be covered with a layer of oiled paper to prevent moisture. At the same time, in addition to wheat and rice, which are used to cook the navy's traditional wheat rice, the submarine also carried a large amount of canned rice.

This is prepared for the inability to use the kitchen pressure cooker to cook rice when diving, these canned rice is mainly glutinous rice cooked with a lot of sugar and red beans, which is the favorite red bean rice of the Japanese, to be honest, the feelings of sailors for this kind of canned food are difficult to describe in words, because even if it is a delicacies from the mountains and seas, you will get tired of eating it every day, but if anyone says that you can't eat this kind of red bean rice, it will definitely be damned.

The variety of vegetables on the Japanese submarines is not too monotonous, with a variety of melons, potatoes and turnips, as well as a variety of dehydrated vegetables and canned vegetables, such as canned bamboo shoots and bean sprouts.

The Yi 60 now carries several cartons of Nerima white radish, and if you want to give it to the Duguo people, it shouldn't have much impact on the later voyage, and the Duguo people are still willing to exchange it for bacon, and I don't know what the taste of the Duguo bacon is.

"Captain Robin, before exchanging supplies, can you allow us to enter your submarine for a visit, although I know it is a bit excessive, but it has been a dream of mine for a long time." Kijima tried his best to make his smile look genuine, but the quivering corners of his eyes completely revealed the nervousness in his heart.

"Of course, Mr. Lieutenant Colonel." Captain Robin replied crisply, and without even thinking about it for a second, he agreed to your request.

"Thank you so much!" Guidao hurriedly sat up straight, and thanked Robin for his solemn bow.
