"Submarine discovered! 1,200 meters ahead! The lookout shouted almost hoarsely, startling the captain as he climbed up the tower.

"Nani!" Hiroshi Hanabo hurriedly took two steps faster to climb the control tower, and then raised the telescope hanging on his chest and looked ahead.

"This is... This is a submarine of the Sole Navy, and it is said that they have been training in this area during this time. Hiroshi Hanabo let out a long sigh of relief when he saw the white German Navy flag hanging on the submarine.

The Japanese Navy's intelligence services are investing more in the Vietnamese intelligence network, but with the exception of some Japanese expatriates and Vietnamese independents, it is difficult to recruit credible agents, both of whom have long been targeted by the French authorities. Especially now that the German intelligence services have also begun to intervene in the counter-espionage work in French Indochina, the Gestapo sent by Germany are no less ruthless than the group of special high-tech police officers who have lost their conscience.

In the early years of the French colonial government, the French colonial government was still concerned with some evidence, and the governor was a man of human care, so even if the evidence of the crime was conclusive, the judge only sentenced him to short prison sentences and exile. When the Germans arrived, the way of dealing with the problem changed, and they set up two huge concentration camps on the outskirts of Saigon and Hanoi.

As a result, since last month, there has been a steady stream of Japanese intelligence that people have disappeared on the territory of French Indochina, and it is estimated that nine times out of ten they have been sent to concentration camps by the French. The government could not even recognize the identities of these people, let alone protest to the French.

The Japanese Navy had set up intelligence stations in both Saigon Port and Haiphong Port, but the intelligence network had been torn apart by the German and French intelligence agencies, and in the end it was the Navy Command Department that went into battle shirtless, and the Japanese naval attaché stationed in French Indochina, desperately in danger of being expelled by the colonial government, spent a lot of money to bribe the officials of the two French port departments, and finally got some valuable information out.

The Naval Command Department paid more attention to the activities of the French Far East Fleet, and those two French battle cruisers were too powerful to fight against any battleship belonging to the Combined Fleet, not to mention the pile of light and heavy cruisers, so before the [Yamato] was officially commissioned, these two French battle cruisers would be the biggest threat to the Imperial Navy in Asia.

However, according to information leaked from the French Indochina government, the French seem to be preparing to recall these two warships at the beginning of next year, supposedly to prepare for modernization, God knows where these two warships are not modern, but this is good news for the Imperial Japanese Navy.

As for the submarine force of the German Navy, the Military Command Department seemed to be completely uninterested, but in fact it was frightened by the ferocious posture of the Germans when they stabbed the army red deer, and in addition, a bunch of hands and tails of the Bishan air battle had not yet been completed, so the upper echelons were afraid that they would not cause any diplomatic disputes because of intelligence work.

The naval staff officers who comprehended the spirit of Shangfeng found a very "logical" reason, and they declared in their report to the Military Command Department that the German boat group was only a passer-by in the South Asian colonies, declaring the existence of an independent country, and that it would eventually return to its base camp in Europe.

And the reason seems to be particularly sufficient, Germany does not have a real military port of its own in Asia, there is neither a shipyard for the maintenance of submarines, nor a professional logistics supply base, especially the parts standard of the German Navy is almost not common to Britain and France, which means that even if it is a maintenance bolt here, Germany has to travel thousands of miles from Europe.

The staff officers declared that no country in the world would incur such high operating costs just to maintain an existing fleet. Instead of sending an expensive submarine detachment, the Germans would have better station an army in Asia, at least cheaper.

In addition to the above, one of the most important reasons is that the Japanese have always believed that without the cooperation of the surface fleet, submarines can only play some harassing role in regular naval warfare. They took the Japanese Navy's own tactics as the starting point, and after "repeated arguments," they finally came to this "scientific" conclusion.

The Japanese Navy did not know about the brilliant performance of the German submarine forces in the British Campaign, because this time Germany did not have the same hype around the world as in history, and the British certainly did not have nothing to expose themselves, except for insiders on both sides of the war, few people knew the exact tonnage of British merchant ships.

In the eyes of the Japanese admirals at this time, they only saw the magnificence and splendor of the decisive battle in the strait of the British and German naval fleets, while the German submarine forces seemed to be playing soy sauce the whole time, and only killed some merchant ships and frigates.

Several frontal naval battles in the European war further strengthened the idea of the Imperial Japanese Navy's fleet for a decisive battle on the surface, and the gradual reduction of the nine-stage formation was the right way to use troops, and all aircraft and submarines were opportunistic, and the final decisive battle had to depend on our big ships and huge guns.

As a result, the warship faction and the treaty faction within the Japanese navy began to quarrel again for five days and three days, because the examples of the European war were placed there, and the treaty faction was now in decline, and the fleet faction began to take advantage of the victory to pursue, and it is said that Admiral Yamamoto Isoroku (who had just been promoted in mid-November this year), who was famous for his extraordinary energy in the past, had some difficulty coping with this time.

The topic is far away, and now back to the scene of the encounter, Captain Robin's identification is not wrong, this is indeed a Haida IIIb ocean-going submarine, and the Japanese Navy officially calls it the I-56 submarine. This submarine, numbered Il-60, is the fourth submarine of its class.

This class of submarine is called Haida Type IIIa, that is, the improved version of the Yi 53 submarine, so it is also called the Yi 53 change by the Japanese Navy, and the equipment within the Imperial Japanese Navy often has several different names, whether it confuses the enemy spies I don't know, from a historical point of view, it should not play much role.

Speaking of this Yi 60, it is famous in the Japanese Navy, and she is the only submarine in the Japanese Navy's diving team that has an "anti-submarine record".

Because on the night of February 2 last year, during an attack training in the Bungo Channel, she personally killed her sister ship, the submarine Yi 63, which is also Haida IIIb.

Speaking of this thing, it was a night training, Yi 63 arrived at the scheduled meeting point in advance, because no colleagues were found, so the captain Sano Takao Shaozo ordered the submarine to stop in place and wait, for safety reasons, Yi 63 also lit the navigation lights on the control tower and stern.

As a result, the problem was with the two navigation lights, and the Yi 60, which then arrived at the assembly site, did not expect the Yi 63 to be lit because it was a violation of the night training regulations. As a result, the captain of the Yi 60 at the time, Nakagawa Zhao Shaozo (looking at the level of the father's name, he had already expected that his son would cause trouble in the future.) I take the lights in the distance for the mast lights of the fishing boats.

You must know that the Haida IIIb is 100 meters long, and it is at least 50 meters from the conning tower to the tail, and the Japanese coastal fishing boats at that time were not so big, and as a result, the conning tower and stern lights on the I-63 were misjudged by Captain Nakagawa to be lit by two different fishing boats, so he did not hesitate to choose to cross in the "middle" of the two fishing boats.

The I-60 did not realize that it was rushing towards its sister ship at full speed until it approached within 200 meters, and because of the lights, the personnel on the I-63 conning tower did not notice the companions approaching at high speed in the dark, and finally the I-60 crashed head-on into the motor room of the I-63 at a right angle, causing the latter to sink to the bottom of the sea in a very short time, and the whole boat survived except for the six officers and men under the captain Takao Sano on the conning tower, and the remaining eighty-one people were all drowned in the cabin.

To say that the magic is still to come, in order to cover up the responsibility of the superior of the naval fleet, no one was punished for this incident afterwards, that Nakagawa Zhao Shaosa was only temporarily transferred from the post of captain, and at the end of October 40, he was actually promoted to Nakasa, and was transferred to the Yi 58 as a captain.

And on the same day, the surviving Sano Takao Shaozo was also promoted to Nakasa, and was transferred to the Yi 70 as the captain.

Historically, the captain Nakagawa survived the war and was sentenced to eight years in prison in Yokohama after the war for shooting at the surviving crew of an Allied shipwreck.

On the third day after the Japanese army's successful attack on Pearl Harbor, he commanded the Yi 70 and arrived near Pearl Harbor to conduct reconnaissance operations, trying to discover the whereabouts of the missing aircraft carrier in Pearl Harbor, and in a sense the captain succeeded, the Yi 70 hit the [Enterprise] aircraft carrier that was returning to Hong Kong at full speed, and before he could send a telegram to report to his superiors, he was bombed indiscriminately by the "Big E" carrier-based aircraft. In the end, the I-70 sank into the vast Pacific Ocean with 93 officers and men of the whole ship.

Now let's talk about the accident of the I-60 submarine, after being towed back to the Sasebo Military Port for careful repairs, the I-60 was restored to combat capability in November of that year, and after replacing almost all the officers, the Sasebo Town Guard gave the submarine a new mission.
