PS: Thank you dongdajie book friend monthly pass. Thank you.

On April 16, 1942, the third day after the two fleets of the U.S. Army and the Naval Resistance Army met. The huge formation formed by three aircraft carriers and several warships is already less than 1,200 nautical miles away from Tokyo, Japan.

At 5:30 a.m. on 18 April, the US-Tang mobile fleet was 700 nautical miles away from Tokyo, Japan. In Cambridge, on the aircraft carrier Liberty Dragon, Li Guang gave an order, and the radio waves immediately flew to the submarine force of the Maritime Resistance Army.

The 1st Submarine Squadron of the Naval Resistance Force, led by Ji Keliang, has four large submarines that can sail long distances, and the area of operation is set around the Japanese mainland. But now there is not only the 1st Submarine Squadron around the Japanese mainland, but also the 3rd Submarine Squadron led by Jeon Yonghai.

Jeon Yonghae's 3rd submarine fleet has only four Raccoon class submarines and has poor endurance. Although it is equipped with a supply ship or a supply submarine, it is not an ocean-going submarine after all, so how can it run to the vicinity of the Japanese mainland?

Because, Quan Yonghai got a German submarine "stunt" from the German submarine captain Lieutenant Colonel Bickerbi.

For a long time, the Naval Resistance Force could not understand why the Germans' 600-ton submarines could fight in the ocean, and some even went to the Indian Ocean or the Pacific Ocean. You must know that the current submarine of the Maritime Resistance Army's Fox class is no worse than the German submarine in many aspects, but it is not suitable for this kind of ocean-going combat in any case.

Quan Yonghai has always dealt with German submarines the most, and a few bottles of good wine were smashed over, and Lieutenant Commander Bickerbi revealed a secret - adding sails to submarines.

What is this trick called? It's an insult to the submarine forces. But what can pull out the pus is a good plaster.

This is indeed not a difficult action, but if you don't break this window paper, it is really hard for ordinary people to imagine that a modern submarine is equipped with ancient sails.

Of the three submarine squadrons of the Maritime Resistance Army, Ji Keliang's first submarine squadron does not need to add sails, because four large submarines can easily make two round-trips from the Japanese mainland to Tang Port. And the second submarine fleet. Ren Tianyang doesn't need it, the scope of his combat is around Sumatra and Malaya, and the endurance of the Lilian-class submarines is completely sufficient.

However, if the third submarine fleet has to afford to attack thousands of kilometers of coastline from the coast of Chinese mainland to the Korean Peninsula, the range of the submarine is seriously insufficient, that is, it is difficult to meet the needs with a Pixiu-class supply submarine, after all, it is not easy to find a refueling site in the combat area. Therefore, this chicken-rib-like stunt was laughed at by Quan Yonghai.

The modification of Quan Yonghai is even more perfect than that of the Germans.

Five thirty.

The first rays of light had already appeared in the central Pacific, and on the golden sea, a small sailing ship with all the Japanese insignia appeared not far from the Japanese patrol boats.

It is located 650 nautical miles from the Japanese mainland. About 1,200 km. The outermost line of defense of the Japanese army's homeland, or rather the early warning line.

It is definitely not right to say that the devils do not pay attention to the local defense at all, and the devils actually pay attention to this. To the east of the Japanese mainland, Japan laid out at least three lines of defense.

The first is off the coast of Japan. It consists of a large number of gunboats and patrol boats, as well as small submarines.

The second, about 400 nautical miles from the Japanese mainland. There are Japanese seaplane carriers and destroyers here. as well as the composition of medium-sized submarines.

The third is about six or seven hundred nautical miles from the Japanese mainland. Most of this line of defense is made up of Japanese fishing boats. A few of them were converted fishing boats, which were directly under the management of the Japanese Navy. The ships had one thing in common, all of them were equipped with telegraphs.

The Japanese patrol ship Nichito Maru 23 is a patrol ship directly managed by the Japanese Navy on the third line of defense. Although it was managed, the ships did not belong to the navy. It's a fishing boat that still runs the old business.

Under the morning sun of dawn, Ichiro Shimizu, the ship's lookout post, spotted a light signal in the distance.

A Japanese ship is heading towards the Nichito Maru 23. Why is it a Japanese ship? Quite simply, the ship is Japanese-style in terms of sails and architecture, and it also flies the flag of the Japanese Navy.

Ichiro Shimizu is just a fisherman. I couldn't understand any light signals at all, so I immediately called the military personnel on the ship, Sergeant Yamamoto Kokiku. This sergeant should be said to be a former sergeant, because he has been retired for many years, and the fishing boat is actually his belongings.

Sergeant Yamamoto, although he is old, can still recognize the light signal: "Stop the boat and get checked." Here is the patrol ship of the Homeland Defense Command of the Japanese Navy. ”

Poor former Sergeant Yamamoto of the Naval Home Defense Command didn't know what it was about, but it seemed to be a big deal.

Yamamoto Xiaoju didn't expect that there would be ships from the Maritime Resistance Army here, and it was a sailing ship. This sailboat is not much different from ordinary Japanese fishing boats, and it is completely Japanese-style.

If it is a warship, Yamamoto Xiaoju will turn his brain a little more, and if it is a submarine, Yamamoto Xiaoju will definitely send a report immediately. But this is just a wooden sailboat, and Yamamoto didn't think about it at all, and of course it is impossible to think of the possibility of the Naval Resistance Army.

Yamamoto Xiaoju didn't think too much, he estimated that the old men of the Japanese Navy came out to raid the work. In the months since the start of the war, the Japanese Navy has not done this kind of thing once or twice, and his Nitto Maru 23 has been checked many times.

Although it seems that the department of inspection is different this time, I didn't take it seriously. Since the chief wants to check, let's check, Yamamoto Xiaoju is conscientious, and even sent additional manpower to monitor the sea at night. Yamamoto Koju considered himself worthy of the emperor's reward of 20 yen a month.

Yamamoto Xiaoju is an old sailor, and he can't figure out why the engine of the sailboat in front of him is a little muffled. But the speed of this boat does not seem to be slow, it is 14 or 5 knots, which is much faster than ordinary fishing boats.

After a while, without waiting for Yamamoto to draw any conclusions, the naval inspection ship was not far from the Nito Maru 23. When the distance between the two boats was still forty or fifty meters, Yamamoto Xiaoju felt that something was wrong.

The inspection boat did not seem to slow down, and it seemed that there was a shadow in the water in front of the inspection boat.

Yamamoto turned his head to look at the rising sun, as if the light was not in the right direction, and the shadow of the ship should not be ahead.

When Yamamoto's doubts were magnifying, he didn't have to worry anymore.

The submarine led by Quan Yonghai not only did not slow down. On the contrary, it is accelerating. Forty or fifty meters away, there is actually not much distance left.

The wooden hull that came out of the water took up less than half the length of the submarine. And the hull of the submarine in front of the watchtower, which is more than 20 meters, when the devil sees that the distance is forty or fifty meters, the submarine is actually less than 20 meters away from the Nito Maru.

When Yamamoto was still confused, the two boats had already collided together.

With a piercing grinding sound, the Nitto Maru 23 fishing boat had been provoked under the water by the Jianwei submarine, and then it was stern down and loaded into the sea.

The Nitto Maru-23 is just a wooden ship with a displacement of less than 30 tons, and for a Jairus-class submarine with a displacement of 600 tons, this is a small grasshopper. Gently and skillfully overturned.

In the early hours of this morning, this scene happened six times on the surface of the sea within a radius of dozens of miles. Although Ji Kelian's submarine team took more violent measures, the huge hull quickly rose from under the surface of the sea, and simply and neatly turned the fishing boat into the sky. These behaviors all have one thing in common, no cannon fired. No torpedoes were used. The Japanese patrol ships did not have time to send a telegram.

It is said that there was a general Zhang (Zhaozhong) who advocated the use of fishing nets and kelp against submarines. Ji Keliang and Quan Yonghai attached great importance to General Zhang's opinion. During the operation, they were very careful to avoid fishing nets and kelp. It's horrible. This is a great weapon of destruction against submarines in the 21st century.

At half past six o'clock, Li Guang received a report from the submarine unit -- that he was safe and sound.

The combined U.S.-Tang fleet continued to advance westward.

This was a task undertaken by the Naval Resistance Force in the bombing of Tokyo, and for this task, the Naval Resistance Force mobilized two submarine fleets and eight submarines. These eight submarines have been preparing in this sea area for more than a week, and the movement pattern of Japanese fishing boats on the sea surface has been clearly felt.

In fact, after the Battle of Ceylon, Li Guang regretted participating in the Tokyo bombing operation. Eight submarines will be delayed for at least half a month. According to the combat efficiency of the current submarines of the Maritime Resistance Army, eight submarines can sink 40,000 tons of Japanese merchant ships in half a month, and maybe if they are lucky, they can even kill one or two Japanese warships.

In short, in Li Guang's thinking, with the deepening of thinking. There is a growing recognition that this is an uncost-effective military operation. However, it was the Navy Resistance Army that proposed this action to US President Roosevelt on its own initiative, and Li Guang had no choice but to continue the military operation.

For the submarine to carry out such a task, the captain of the first submarine team, Ji Keliang, was the most unhappy, which delayed his exploits too much, and the competition between Ji Keliang and Ren Tianyang was quite fierce.

Quan Yonghai doesn't have much opinion, this guy is cunning. His main mode of combat now is not to rely on torpedoes, but on mines.

The Maritime Resistance Force once captured nearly 2,000 mines of the Italian army in Somalia, including trigger mines and magnetic induction mines. Quan Yonghai learned that the American submarines had no torpedoes for a while, so they could only arrange mine operations. The bad boy immediately began to turn his brain, and for two months, the submarine he led barely used a few torpedoes, and was busy laying mines on the shipping lanes of the Japanese mainland.

The supply ships of the third submarine flotilla are now in a very clever position. The best way to hide a drop of water is to place it in the ocean. Jeonyonghae's supply ship now looks like a standard Japanese patrol ship, and it also undertakes the task of reconnaissance for the Japanese army. Because this patrol ship was robbed by Quan Yonghai, but now the ships are all fighters of the Maritime Resistance Army.

In the two exit lanes of the Seto Inland Sea in Japan, the entire Naga Sea is fully equipped with 600 mines of various kinds. This tactic makes Quan Yonghai not worry about his results, maybe when the results will be delivered to the door by himself.

In Quan Yonghai's words, this is called a clever battle. As a matter of fact, Quanyonghai's mine tactics were extremely harmful to Japan's economy and seriously constrained the Japanese army's military strength. To the Japanese and Japanese merchant ships was no less of a threat than a torpedo from a submarine.

Historically, the U.S. aircraft carrier was discovered by the fishing ship Nitto Maru, and had to take off the bomber in advance, but the Maritime Resistance Army solved this problem, so the three aircraft carrier formations continued to sail west this morning, preparing to take off the bomber about 400 nautical miles from the Japanese mainland according to the plan.
