lost half of the country, and it is the best half, military, diplomatic, financial, and foreign trade have failed completely, this is Chang Kaishen's current predicament; Thirty meters below the sea surface of Qinzhou Bay, it was Li Kongrong's pain that more than half of the torpedoes were used. The sound of propellers of Japanese transport ships was all overhead www.biquge.info, and there were only six torpedoes in the front and rear torpedo compartments combined. If he could have the infinite function of torpedoes, he would definitely be able to sink all the floating ships at sea, but no, he could only stare dryly.

Deck guns and the like were of no avail, 20 guns could fire as soon as they floated, but 20 guns could not sink merchant ships; The 105 guns can be sunk, but when the gun carriage is deployed and the shells are taken out, the Japanese destroyers are afraid that they will already rush over, and in order to reduce the underwater navigation assistance of the deck guns, the two deck guns do not have gun shields, which is equivalent to saying that if the distance is close enough, the rifles can kill the gunners. The only thing that can be dealt with by the Japanese landing is the large hair boat and small hair boat used by the Japanese landing, but in this way, the submarine must float between the merchant ship and the coast, except for the three-kilometer-wide bay mouth where Qinzhou Bay goes out to sea, the water in other places is not deep, and it is not good to go there to float and run aground on the seabed, and it is difficult to end up at that time.

Li Kongrong was entangled, and the officers in the control cabin were waiting for him. In this situation, no one has a good way, so I hope he can think of the idea of expanding the results of the battle. didn't want to wait for a long time, but Li Kongrong said in annoyance: "Six torpedoes, except for the first two, let's put them apart." Try to cause panic and drag it out until dark. ”

"Separated?" Gao Guangyou is not sure why, it means that you have to stay in a fixed sea area all the time, otherwise you will have to spend electricity to go around in this sea area, neither of which is a good choice.

"Yes. Bai Jiansheng's meaning is to delay and disrupt the enemy's landing, the delay is to prepare for the army on the shore, and the disruption is also to delay, and the other is to hope that the Japanese army will make mistakes, such as heavy firepower and baggage, if there is a mistake when transporting it ashore, it will affect the combat effectiveness of the Japanese army after the landing. Li Kongrong said his opinion on the landing, and he immediately looked at the water listening room, "Is the active sonar turned on?" ”

"Not yet." Liu Yongren bit the tip of his pencil. He is the navigator and, according to his duties, is responsible for marking the location of enemy ships on charts when active sonar is turned on. However, now the U-38 itself cannot accurately determine its own position, so the position of the enemy ship cannot be marked at all, and all that can be drawn is the position and distance between the enemy ship and itself. With the performance of active sonar, this distance is no more than 1,800 meters, and more precisely, the distance is less than 1,200 meters.

"Then turn it on first." Li Kongrong said. "Don't worry about the Japanese army discovering it, this is near the sea, and the sonar that can find us hasn't been built yet."

"Yes." Lu Ruping was standing at the door of the water listening room, he was the head of the small room. "Turn on active sonar." He turned his head to Lin Lianfan, who was in charge of water listening, and Lin Lianfan immediately turned on the CT monitor switch - because it was equipped with an electronic tube, the monitor could only be used for at least half an hour, and when the monitor was warmed up, the active sonar on the front of the enclosure would be turned on.

"Sit and sink first, and then search for enemy ships after turning on the plane." Li Kongrong didn't think that the display had not yet warmed up. He took off the white captain's hat from his head and said, "Start eating right away, and then fight after breakfast." ”

Breakfast had already been prepared, but it had been hot in the kitchen because of the battle. As soon as Li Kongrong said that everyone's stomach was rumbling when the meal was opened, everyone was hungry until now.

The shelling on the sea continued, and the 5th Fleet seemed to be about to run out of shells it was carrying, and the artillery fire continued for three hours. Standing on the bridge of the Torikai in the rain, Rear Admiral Tafumi Yamaguchi, chief of staff of the 5th Fleet, wore a raincoat and observed the situation on the coast through a telescope. Disturbed by the rain and artillery fire, it was difficult for him to see clearly, he could only see the stretch of coast to the mouth of Qinzhou Bay and fold in, the scenery on the shore was completely different from Sanya, there were no coconut trees, and there were not many houses to see, only the Qingtian and White Sun Flag erected on a small hill was the most conspicuous. The gun commanders of each ship should have seen this flag, and the shells rained down, and in a moment the flag was covered by artillery fire.

"Your Excellency, Lin Li Shaozo reported a malfunction of the hydrophony equipment and could not be used to search for the Shina submarine." The staff of the fleet reported to Yamaguchi Tawen, which had been reported a few minutes earlier by the flagship of the 5th Destroyer, the Asakaze.

"Glitch?" Yamaguchi Tawen could have commanded offshore Haikou, but in order to sink the Shina submarine, he stayed on the Chokai.

"Yes. There are similar reports on the sub-day. "Ziri is the second ship of the 21st Destroyer, because she was injured in the collision between the flagship Chuchun and the merchant ship last night, and she became the flagship.

"That's right." Yamaguchi responded helplessly. At this time, the Navy's minesweepers were still clearing mines, and once the minesweeping was completed, the marines and army divisions would begin to land on the beach, and the first place to land would be Qisha on the west side of the bay mouth, which belonged to the 5th Brigade of the 9th Division; then Huangwutun, west of Qin County at the bottom of the bay, the 21st Brigade; Finally, there is Litouzui, south of Qin County, where the Taiwanese mixed brigade is formed.

The landing plan was carried out one after another, first outside Qinzhou Bay and then inside Qinzhou Bay, with intervals of several hours. But now everything is chaotic, originally it was a feint to attack the Beihai first, and then seize the beach of Qinzhou the next day, but now the feint is not a feint, it is tantamount to a strong attack, and the Chinese army also seems to be ready, the mountain pass does not understand the army, but the minesweepers report that the mines in Qinzhou Bay are all over the place, and there are heavy guns and mortars of the Zhina Army on both sides of the bay, and the minesweepers can barely clear a road until at least in the afternoon.

I wish he was gone. Yamaguchi Duowen had to look forward to it so much, but his expectations could not be realized at all, in the U-38 cabin, Li Kongrong, who had eaten several bowls of flat meat in a row, wiped his mouth and walked to the chart table, at this time the active sonar had just been turned on, Lin Lianfan bowed to the monitor before starting to work, Li Kongrong looked at his pious appearance and smiled: "Why, if you don't respect it, won't it start?" ”

"This ......" In Lin Lianfan's opinion, the captain said this is obviously disrespectful, but he can't say that the captain said wrong, and his face was suddenly full of sorrow, and Lu Ruping on the side said: "It's very mysterious, sometimes you can't see anything when your temper comes up." ”

"It's really going to be coaxed." Li Kongrong thought of the radar during World War II, when the radar operators of the US military called their radars "babies"; when the technology was not yet mature, each set of equipment had its own temper, and it would not work if it was not coaxed.

As Li Kongrong spoke, the sonar had already begun to work. The display is borrowed from the radar display and uses a long afterglow cathode ray tube (CRT), and there is no epoch-making digital technology, so it is naturally an analog display, and the display form is a single beam, so it adopts an A-type display. This is the professional explanation given by the research, Li Kongrong did not delve into it, what he knows is that the display is borrowed from the display mode of the hospital CT machine, and then there are countless failed experiments.

The whole display is simply a light point and a line, the picture is somewhat like the ECG monitor of later generations, but the ECG is similar to lightning, which will fluctuate up and down the horizontal line, and the sonar display in front of you is only displayed above the horizontal line. The highlight of the crest on the left is the active sonar, representing the U-38 boat, and the right side is the echo with a smaller crest, there are some scales between the two crests, representing the distance of the echo, under normal circumstances, the crest of the echo is constantly moving, because both sides are moving, but this time the crest of the echo after the active sonar is turned on is extremely disordered, which startled Lin Lianfan.

"Chief Engineer, horizontal steering." Li Kongrong ordered the control cabin, and at this time the submarine had already floated from the bottom of the sea.

"Right full rudder. The left man moves forward slightly, and the right man moves back slightly. Su Jinghu pulled the bell, and the 76-meter-long body of the U-38 slowly turned in the sea. As it turns, the echo gradually transforms, and when it turns to a certain position, the echo finally returns to a point of light.

"There are too many boats." Li Kongrong said. "Now we're only facing one, how far is it?"

"A thousand... Fifteen hundred meters. Lin Lianfan said and explained, "Sir, the scale is not very accurate, I used to ......."

"Torpedo tube No. 1 ready." Li Kongrong only nodded to him, the current sonar is all experienced, only the operator knows its temper, Lin Lianfan said that it is 1,500 meters, that is, 1,500 meters.

"What is the bearing and speed?" Li Kongrong asked him again, these two data displays did not show, and they were even more empirical.

Active sonar borrows the advantages of passive sonar, which can move at a certain angle and determine the target orientation with binaural effect. Lin Lianfan has used headphones to determine the direction of the target, and combined with the changes in distance and bearing, the speed of the target can be calculated by trigonometric functions. This is already the limit of artificiality, and the submarine should be as stationary as possible at this time, so as not to add new variables to this multivariate equation. Li Kongrong's gaze made his head sweat, and after another silent calculation, he confirmed: "The speed of the enemy ship is eight knots, and the azimuth is 054." ”

"The enemy's ship is 054 in azimuth, 1,500 at a distance, and 8 knots at a speed......" The parameters reported by Lin Lianfan were directly converted into orders, and each sentence was repeated by the crew who entered the shooting parameters.

"The depth is three meters, and the torpedo speed is forty-five knots." Li Kongrong gave the final order. After a while, the forward torpedo compartment came with a report that No. 1 had been prepared. "One launch!" He waved his hand suddenly, and then said, "The left is full of rudders, and the two planes are moving forward at full speed." ”

"One launch!" The bow torpedo compartment Chang Xiangqi also waved his hand suddenly, and with the sudden lightness of the bow, the No. 1 torpedo came out of the tube, and the U-38 urgently avoided to the left, so as not to be discovered by the destroyer because of the torpedo track.

The sea was stormy, and the white track of Torpedo No. 1 at high speed went unnoticed. It wasn't until the merchant ship on the outer side of the fleet suddenly exploded into a column of water that the hearts of the Japanese soldiers on the sea suddenly sank to the bottom: the Shina submarine came again.

"Your Excellency......" On the bridge of the ship, the captain of the ship, Goro Kouda, pointed to the merchant ship that sank in the middle of the mine, and his expression changed greatly.

"Signal to all destroyers and army transports," the fleet staff officer had just reported a search for the enemy, and Yamaguchi was well aware. "Drop all the dinghies, bring grenades and flare guns, and each dinghy is arranged five chains from the front and rear. As soon as a submarine periscope or a mine trail is found, a grenade is used to expel it and a flare is fired. ”

"Nani?" Goro Kouda was surprised that he didn't understand why the chief of staff would adopt this idea.

"Need I repeat it again?" Yamaguchi looked at him.

"No, I don't." Goro Furuuda was just surprised by this search method, not that he didn't understand it. He immediately had the signalman sound the flag, asking each merchant ship to lower the dinghy and then separate at a distance of five chains. More than 60 merchant ships and 11 destroyers, plus the existing landing boats, for a time the sea was densely covered with small boats.

Of course, Li Kongrong, who was underwater, did not know that the Japanese had set up a monitoring net on the sea with hundreds of small boats, and the entire U-38 boat was still immersed in the joy of hitting enemy ships, especially Li Kongrong -- relying on sonar to attack could only be imagined before, and even if it was tested several times in the United States, it was impossible to really determine the feasibility of the method without actual combat testing. Now that he could finally declare that the sonar attack was indeed effective, he would surely be ecstatic if Dönitz had been informed of this through a German spy at the Swiss Institute.

The crowd cheered for a moment, and then they held their breath and fell silent. In order not to attract the destroyers, the active sonar was turned off, only the monitor was on, but it was strange that the Japanese destroyers only patrolled overhead and did not drop depth charges.

"Did you run out of bombs last night?" Gao Guangyou is very optimistic, the water here is shallow, the Japanese must resist by throwing depth charges, and if the luck is not good, everything will be over.

"I don't know." Li Kongrong also couldn't figure out the situation on the surface, and he wanted to float up to the periscope depth on several occasions and stretch out the periscope to see the situation on the sea surface, but reason still stopped this thought, especially now that the launch of the first torpedo has come on his behalf, the Japanese will definitely strengthen the monitoring of the sea surface. "How's it going?" He asked the water listening room.

"Situation ......" There are boats all over his head, and the headphones are very noisy, and Lin Lianfan can't say what the situation is.

"Turn on active sonar and take a look." Li Kongrong said.

"Yes". The active sonar is turned on for the second time, and with the opening, the monitor is chaotic again, and the crest of the echo does not jump regularly, as if it wants to break free from the shackles of the monitor and take off the screen.

"Is the sonar broken or is there too many boats?" Li Kongrong asked, he couldn't understand it either.

"Report sir, if it's not broken, it's too many ships." Lin Lianfan replied like this, and he didn't have a bottom in his heart, after all, the target of the test was only a merchant ship entering the Kennebek River, and there was no sea full of ships like this.

"Engine, twin slight speed, direction zero ninety-zero." Li Kongrong had to try a different position, but the speed of the submarine was too slow, and he had to wait patiently.

"Your Excellency, will the Shina submarine still appear?" More than 700 small boats were laid out in a square area of 24 kilometers in length and width, and more than 60 merchant ships were concentrated in this area. The submarine will be spotted by the boat on the surface of the sea if it sticks out of the periscope from any place to attack, but Goro Uuda is worried that the submarine will be gone.

"He'll be back." Yamaguchi smiled at the corners of his mouth, and he admired more and more the courage of the submarine commander. (To be continued.) )
