Li Zhaoshui's battle plan for each submarine squad was to arrive at the combat area first, with the four Lanfang-class submarines taking cover in the open sea, and two Xinhua-class submarines escorting the four mine-laying submarines to mine first, and after the mines were laid, all of them would retreat to the open sea to ambush passing merchant ships and warships. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Lanfang-class submarines try their best to attack merchant ships, and try to let Xinhua-class submarines attack after discovering Japanese warships, and Xinhua-class submarines can attack without surfacing when they launch an attack, and the concealment and attack effect will be better, and ocean-going minelaying submarines have the largest number of torpedoes and can attack freely.

The first to reach the destination was the 9th Submarine Group, which arrived near Kuroshima at 11 p.m. on the 27th. The captain ordered four Lanfang-class submarines to stand by here, the deputy leader led two ocean-laying mine-laying submarines to mine the Osumi Strait, and he himself led two ocean--laying mine-laying submarines to Kagoshima Bay to lay mines.

The Osumi Strait runs northeast-southwest and is about 24 kilometers long and 33 kilometers wide. The water depth is 80~150 meters, and the bottom is muddy, sandy and coral. There are few reefs in the strait, and there are no obstacles to navigation, which is suitable for ship navigation and submarine underwater navigation. The Osumi Strait is an important sea route between ports in the East China Sea, the Yellow Sea, and the Sea of Japan in the Tsushima-Korea Strait and ports on the east coast of Japan.

The submarine first sailed to the northeast exit of the strait, turned around, sailed in an S-shape, maintained a speed of 4.5 knots, and then laid 1 mine every 3 minutes, and when it returned to the southwest exit, 42 mines were also laid, and the distance between each mine was about 450 meters.

When I returned to the west entrance of the strait, it was already 5 o'clock in the morning, and I immediately surfaced and began to charge the battery, and contacted the team leader and the four Lanfang-class submarines to retreat westward, at least to the west of Heidao to ensure safety.

At this time, the team leader also finished laying mines and was rushing back from Kagoshima. The team leader did not enter Kagoshima Bay this time, but arranged the mines on the narrow waterway between Ibusuki City and Minami-Osumi at the exit of the bay, and more than 80 mines were distributed in such a narrow area, so it can be said that the mines were dense, and if the ships in the bay wanted to enter and exit, at least 8 of the ten ships would be sunk.

The opinion of the team leader is that this place is too close to the mainland, and it is necessary to retreat at least 100 kilometers to the west, and ambush the passing Japanese ships there, and there will be no one to rescue them after they are sunk.

On the morning of the 28th, the 9th Submarine Squadron sailed westward, looking for prey. The principal and deputy team leaders each led 4 submarines, lined up, with a distance of about 1 kilometer between the submarines and sailing at a speed of 7 knots.

Now, having defeated Tsarist Russia, Japan is one of the new powers. Of all the countries in Asia, the Japanese navy was the strongest, and the self-confidence of the Japanese merchants was inflated, and they did not expect that any country would dare to attack the idea of Japanese merchant ships.

At 10 o'clock in the morning, the submarine where the team leader was located found the first prey, which was coming from the direction of Shanghai due west, and should be a 5,000-ton cargo ship in terms of volume, with a deep draft, heavy cargo, and a speed of about 9 knots.

5 submarines began to move to the specified positions according to the order, and all submarines began to sink below the surface. The vertical distance of a merchant ship on a submarine is about 1,000 meters.

The first Lanfang-class submarine released a periscope, and the captain began to lock on to the target; The submarine operator adjusts the depth of the submarine according to the requirements of the captain;

The captain began to give the order: "Open the launch port pressure cover!" ”

"Report, the launch port gland has been opened!"

The captain continued to look into the periscope to observe the speed and position of the Japanese merchant ships;

"Torpedo tube air valve No. 1 is inflated and standby!"

"Report, the No. 1 torpedo tube air valve is fully inflated!"

The captain calculates a reasonable launch time based on the speed and distance of the merchant ship and the speed of the mine after launch, "Torpedo Tube No. 1 is launched!" ”

"Report, Torpedo Tube No. 1 has been fired!"

There are no traces of navigation on the water after the launch of the trackless electric self-homing torpedo, the noise is very small, and the current merchant ships do not pay attention to it, and the existence of the torpedo cannot be detected at all. The submarine did not dive and escaped, and the captain continued to observe the Japanese merchant ship through the periscope.

The people on the Japanese merchant ships did not know the danger was coming.

The torpedo was launched and sailed forward at a speed of 24 knots, and automatically searched for the target of the attack.

81 seconds later, with a loud bang, the torpedo hit the stern of the Japanese merchant ship, and more than 270 kilograms of explosives exploded, directly blowing up the tail of the merchant ship with a large filling and thin skin, the keel was broken, the merchant ship became two halves, the sea water poured into the frenzy, the bow of the front part was raised high, the crew on the deck was thrown into the sea, and the tail was directly blown into the air, and then smashed on the sea surface, and quickly sank into the sea.

The crew inside the submarine excitedly began to shout, "Hit!" "We hit! ”

The captain smiled with relief: "Don't be too happy, it's not good to be too excited, we just sank a small merchant ship, and it's not worth everyone's excitement." ”

"Captain, it's not about sinking merchant ships or warships, it's about our good start and opening the record, which is what makes people happy."

"It's nothing, this is the credit given to us by the team leader, and the next time we eat, everyone will give the team leader a few more glasses of wine."

"Yes, Captain!" The seamen replied in a loud voice.

The captain kept an eye on the periscope until the entire merchant ship sank completely into the sea along with the cargo.

At this time, there was a lot of garbage floating on the sea, and a few lucky sailors were floating on the sea with wooden planks waiting for rescue, and they were glad that they jumped ship in time and did not sink with the ship, and they were able to catch a plank on the sea, which was really blessed by Amaterasu.

The team leader sent a telegram that the Lanfang-class submarine was sailing westward, and the transport submarine cleaned up the battlefield, killed the crew member who fell into the water, and then evacuated westward.

Two transport submarines surfaced, and the Japanese crew who had fallen into the water looked at the behemoth that suddenly emerged from the sea, and thought that they had encountered a water monster. The rapid-fire guns on the submarine fired, "bang, bang, bang......", and it didn't take a few shots, and before the Japanese crew could react to what was going on, they became minced meat, staining the surrounding sea red, and they would soon become a delicacy for the surrounding sea fish. When the blood cleared, and only a few pieces of wood drifting with the waves were left on the sea, no one would have thought that a merchant ship had just been sunk around here.

In one day, the 9th submarine team hunted and killed 6 Japanese merchant ships, leaving no traces.

The Osumi Strait is a busy waterway, with more than 100 Japanese ships passing through it every day.

On the 28th, three merchant ships were attacked by mines, the ship sank, and less than half of the people survived, and the surviving crew agreed that the ship was in normal operation, and suddenly there was a violent explosion from the bottom of the ship, and then the ship was destroyed and people died, and those who survived were lucky.

On the 29th, five more merchant ships were attacked by mines, and the ships were blown up and sunk.

On the 30th, four merchant ships were sunk in the Osumi Strait waterway.

On the 31st, two more merchant ships sank in the Osumi Strait, and only eight survived.

Since then, the Osumi Strait has become a forbidden area for Japanese merchant ships, and the Japanese Navy has arranged patrol ships to be on duty at two exits of the strait, prohibiting any ships from passing through the strait, and all of them have detoured.

There are also such incidents at the exit of Kagoshima Bay, where several merchant ships have been sunk in succession; 1 light cruiser, 1 destroyer and several merchant ships were sunk in Sasebo; Five merchant ships were sunk in Nagasaki, and no ship dared to enter or leave the port of Nagasaki; Fukuoka and Kitakyushu also experienced the same magical events as Nagasaki and Sasebo; The Guanmen Strait has now completely stopped sailing, and cross-strait personnel and goods exchanges have been completely suspended.

On the 29th, the 8th Submarine Squadron and the 9th Submarine Squadron got in touch, converged in the eastern part of the East China Sea, and began to frantically hunt Japanese merchant ships from the direction of the Bohai Sea, the Yellow Sea and the East China Sea, as of the 31st, the two squadrons sank a total of 47 Japanese merchant ships, each time they will try their best to destroy the evidence, if the sinking speed is slow, they will make up another torpedo.

The 6th and 7th submarine squadrons, in the same amount of time, were also frantically hunting merchant ships transporting goods from the direction of Korea back to Japan.

In less than one week, Japan lost 100 merchant ships, and there are many mysterious missing ships under investigation. It caused panic in the whole of Japan.

Zhang Wei's system score has risen wildly, and now it has risen by more than 400,000 points, and the cost of buying submarines is almost earned.
