The submarine 'advanced' along the Travi River at a speed of four knots, and with the speed of the river, Li Kongrong estimated that his speed was about seven knots, but it was unsightly that the submarine was going backwards. When Liu Yongren, the navigation officer of the pen ~ fun ~ pavilion www.biquge.info climbed the control tower, he smiled embarrassedly and scolded himself, 'Kill you'.

The shipyard is located at the penultimate bend before the Telavi River exits the sea, and the long bend leads to the sea, where there is not only a large lake, but also the Lübeck border checkpoint. Liu Yongren went to the control tower to determine the course - although the Telavi River is more than 400 meters wide, but the channel is not wide, Lin Zhun had specially chartered a merchant ship to travel in this section many times, Liu Yongren was paying close attention to the route chosen by the German pilot, and now he went to sea, he came up to act as a pilot.

Liu Yongren, who came up, did not care whether the submarine was moving forward or backwards, he carefully observed the reference objects on both sides of the river, and many times suggested that Li Kongrong slow down and 'advance', or even stop. The night was too dark, once the moonlight was blocked by the clouds, the entire Travi River would be black, and the riverbank next to it was a little white, if it weren't for Liu Yongren, Li Kongrong would really think the riverbank as the Travi River.

It took half an hour for the submarine to sail into the wide water before the Telavi River entered the sea, where Li Kongrong finally ordered the steering gear to return to the rudder 180 degrees, turning the submarine into a bow facing forward and stern facing backwards. Then he didn't immediately give the order to move forward, but just called Su Jinghu up, and the three of them whispered on the control tower how to sail through the last leg of the journey before entering the sea.

"Is there enough power?" The most worrying thing is the amount of electricity, and Li Kongrong was the first to ask about the amount of electricity.

"It should be enough." Su Jinghu has also been paying attention to the amount of electricity, and now the power pointer is in the position of three, just four.

"Where's the high-pressure gas?" Li Kongrong asked the second question. The border checkpoint in front was brightly lit, and it was impossible for the submarine to fool the past, and the only way was to dive, but the water depth of the estuary was about 12 meters, and the height of the submarine was 9.5 meters. There are two risks, the first is the fear of encountering merchant ships entering the port when going to sea, so the result is self-evident, and the second is the fear of running aground, whether it is the two dangers, high-pressure gas is crucial.

"Enough." There was no problem with the submarine's high-pressure gas system, and Su Jinghu checked the high-pressure gas as soon as he got on board. "But I think it's better to test it here first, I'm afraid there is a problem with the pressurized water tank."

Su Jinghu is an old man, Li Kongrong nodded and said, "Then dive down immediately and see if there is any problem." ”

The diving hatch door was closed, and the passages were closed. Rong Ying and Jiang Jing struggled to open the valve. 'Boom...', the water poured into the main water tank with a slight sound, and a cloud of mist rushed out of the gunhole on the deck, and then the slender hull slowly sank into the water, but because the water was so shallow, the conning tower was only half submerged, and the whole submarine was already sitting at the bottom.

"It doesn't seem to be a problem." Li Kongrong smiled, and several other people also laughed with him. "Let's check around and see if there's any leakage." He commanded, but in his hand he held the coat that the German captain had left in the captain's quarters—it was a captain, and he ******** button up the white captain's hat again. "It's a pity there are no mirrors." He said regretfully.

"Float." Li Kongrong threw down the white captain's hat, and he felt that now was not the time to wear it.

The sound ......of 'sneering' high-pressure gas pouring into the tank was extremely loud, and the submarine sitting on the bottom shook a few times, and finally surfaced again. Li Kongrong and Liu Yongren soon returned to the conning tower.

After confirming through the telescope that there were no merchant ships entering the port immediately, Li Kongrong exhaled, "There is still one nautical mile left." ”

"This bend is divided into two sections, the first section is 820 meters, and the water depth is about 8.4 meters to 10 meters; The section after the 76-degree turn is about 1,005 meters long, and the water depth is 10.2 to 13 meters. The whole channel is about 150 meters wide, and the narrowest part is more than 80 meters, and the mouth of the river is often cleared by the Germans, and there is little siltation. Liu Yongren was also very nervous, and the hydrological information provided by the British, which he had memorized before, now blurted out.

"What's the most dangerous part? What is the river flow rate? Li Kongrong repeated these numbers in his mind, and finally asked the speed of the river, and when he passed through the checkpoint, he had to submerge the submarine in its entirety, so he needed to accurately calculate the speed and flow rate of the boat.

"The flow rate is around three to four knots this season. The section of the checkpoint is faster because of the narrow river channel. Liu Yongren explained.

"From now on, sail according to the charts." Li Kongrong finally decided that the first paragraph should also be based on the nautical chart navigation, "I am on it, and if I find something wrong, I will correct it immediately." When we got to the corner, we dive. ”

"Yes, sir." Liu Yongren agreed, and the person immediately drilled down.

"Attention to all cabins, keep semi-submersible, this section is sailing according to the chart." Li Kongrong gave the order into the microphone. Soon, the submarine was launched under Liu Yongren's orders.

The distance of 820 meters is not far, and in about ten minutes, the submarine will go to the bend, and Li Kongrong closed the hatch at this time and walked to the command platform: "Now I am in command." Engine: dive to periscope depth; Fifteen degrees on the right rudder, seventy-six degrees to the right. ”

"Dive to periscope depth. Fifteen degrees on the right rudder and seventy-six degrees on the rudder. Su Jinghu and Xu Zhenqi, who was at the helm, repeated his orders, and while the submarine was diving, the hull of the submarine began to turn right.

Navigation officer Liu Yongren was counting the seconds from the beginning of the rudder, and fifteen seconds later, he immediately made a gesture to Li Kongrong to return the rudder, and Li Kongrong immediately ordered: "The rudder is right, and the rudder is set." "Then he looked at the embankments on both sides with a periscope, but the vision inside the periscope was so bad that he couldn't see anything.

"The servo is ruddering, set." Xu Zhenqi repeated the order, and the servo immediately returned to the rudder.

"The duo moved slowly. All compartments pay attention to grounding collisions. Since he couldn't see it, he could only sail according to the chart, and Li Kongrong wanted to cross the estuary as soon as possible, and gave the order to slow down while retracting the periscope.

"Slow ahead." The engine room quickly returns to the clock. The hum of the electric motors became louder, and everyone in the cabin felt the submarine speeding forward.

The Lübeck checkpoint was brightly lit, and the clock had just passed ten o'clock, and the time for the shift had not yet arrived. As usual, the mighty river of the Telavi River flows calmly and horizontally through checkpoints and hastily flows into the Baltic Sea. No one knew that there was a submarine more than seventy meters long under the calm waters, even though the head of the border police station, Captain Alexander John, was walking on the embankment.

Captain John on the embankment was extremely leisurely, and in the submarine below the river, Li Kongrong, who was sweating profusely, constantly ordered the chief engineer Su Jinghu to maintain the depth and level - the river was too shallow, and the submarine kept touching the bulge at the bottom of the water, but fortunately, the riverbed at the mouth of the sea was full of sand. The submarine advanced meter by meter, every second was torment, but the further it went to the sea, the deeper the water became, and after five minutes, the submarine finally stopped stumbling and the navigation became smoother.

"Five hundred meters ......, four hundred and fifty meters ......, four hundred meters ......" Liu Yongren was reading with a stopwatch, and everyone breathed a sigh of relief as the numbers reported became smaller and smaller. Report sir, we sailed out of the estuary. Ten minutes later, Liu Yongren reported excitedly.

"Right rudder five." Li Kongrong wiped his sweat and gave the order again. "Full speed ahead."

Sailing out of the Travi River finally relieved Sujing Lake, although the power was not much, it was finally able to leave the shore and start charging. When the power was about to run out, the submarine finally surfaced ten kilometers from the coast.

"Mazu bless!" Several people said in unison, the most pious is the king. Rong Ying and Su Jing Lake. Li Kongrong also secretly exclaimed in his heart, but he didn't put his palms together.

"Start the diesel engine." He waited for Su Jinghu and the others to finish silently before giving the order.

"Start the diesel engine." The order was transmitted to the power compartment, and Chen Ergong, who had been waiting, spat and foamed at the mouth before pulling the starting handle of the diesel engine, and with a few soft sounds of the piston, the diesel engine on the right side rumbled and roared.

"It worked!" When the two diesel engines roared together, Su Jinghu slapped his thigh with all his strength, and then punched Li Kongrong twice. "Hansheng, we succeeded!"

"It's good if it works." In the section before going to sea, Li Kongrong's heart mentioned his throat, and now when he heard the roar of the diesel engine, he suddenly felt that his whole body was prostration. "Five on the left side, full speed ahead for both sides." He commanded. When the engine room returned to the bell, he looked at Lin Huiping: "No, I want to rest for a while, you take over." ”

"Okay, you go first, and replace me after dawn." Li Kongrong's face turned a little pale, this plan was planned with all his strength from beginning to end, and the pressure was not small. Although Lin Huiping has never commanded a submarine, as long as he does not dive, this is a boat, not to mention that Jiang Jing, who specializes in navigation, will go up to the command tower with him to lookout.

"Lin Huiping takes over the command." Li Kongrong staggered to the captain's room after giving the last order, and he first recorded in detail the process of undocking and entering the sea in the logbook, and then leaned on the captain's unique large ship to look through the logbook described by the previous captain.

This submarine is the second submarine of the IXA type: U-38. It was built by the Bremen shipyard and was launched on August 9 last year and entered service on October 24. On April 13 this year, while participating in an underwater attack exercise in the Baltic Sea, the U-29 collided in a storm and hit the stern of the boat, when the bow of the U-29 pried up the entire stern of the U-38, and the propeller, rudder and gearbox in the tail were immediately damaged, and a large amount of water was flooded in the stern. Fortunately, the sailors plugged the breach and saved the submarine. The submarine was then towed by tugboat to the nearest shipyard in Lübeck for repairs.

The logbook not only details the collision on April 13, but also records the submarine's training before, and Li Kongrong also saw a straightforward description on one of the pages of the logbook, such as 'the snorkel is really a nightmare', and it is clear that Dönitz equipped the submarine with a snorkel before history.

The U-38's training record is very valuable, which Li Kongrong wanted to learn but did not learn. But after a cursory flip through the logbook, he suddenly remembered that he didn't seem to have received a report on the submarine's armament. I don't know if I have a torpedo or not, Li Kongrong put down the logbook and stood up, he walked to the command platform and asked Su Jinghu: "Have you checked the torpedo compartment?" ”

"Nope." Su Jinghu is working with Wang. Rong Ying, Xu Zhenqi, and Liu Yongren smoked cigarettes, and scratched their heads embarrassedly when Li Kongrong asked about torpedoes, he didn't go to the torpedo compartment at all, he just thought about how to drive the submarine out of the mouth of the Travi River.

"I'll take a look." Li Kongrong took the cigarette handed by Su Jinghu and said. At present, the division of labor is that Lin Huiping and Jiang Jing are responsible for lookout, Xu Zhenqi is in charge of the rudder, Liu Yongren is in charge of navigation and hydrophones, and Wang is in charge of navigation. Rong Ying was in charge of the gate and high-pressure gas with the assistance of Su Jinghu, and Chen Ergong and Xia Xin were in charge of the power cabin. Everyone is busy, only he is idle.

Type IXA submarines have six torpedo tubes, one more than Type 7A, and the distribution of these six torpedo tubes is four in the front and two in the rear. Since everyone was in the aft cabin, he walked straight past the captain's room, then the officer's room, the galley, the non-commissioned officer's room, and the sailor's room before coming to the bow torpedo room at the very front. Before he could enter the cabin, he saw four torpedo tubes and two rails for loading and unloading torpedoes hanging in mid-air. On both sides of the guide rail were torpedo racks, and he regretted that there were only eight torpedoes on the torpedo racks, and the thunder heads were all training mines.

In general, the torpedo tubes in the bow are not torpedoed, while the torpedo compartment in the stern does not have a torpedo mount, and only the torpedoes are loaded in the tubes. This means that the entire submarine has ten torpedoes, and all of them are training mines.

"It's bad luck." Although he expected the result, Li Kongrong was still annoyed. He went back to the captain's room and opened the logbook, which was exactly what he saw. Because it was only an exercise, the submarine was equipped with training mines, a total of ten, eight in the front and two in the rear, but the 105mm foredeck guns, the 37mm rear deck guns, and the 20mm anti-aircraft guns in the conning tower were loaded with live ammunition, but the number was not much.

"What a wolf without claws." Li Kongrong closed the logbook in disappointment, and then looked at the radio room opposite and thought of the code book and the code machine, the result of the search was the same as he thought, when the submarine sailed into the dock for maintenance, the code book and the code machine were taken away by the radio officer, and even the telegram script was gone, leaving only the radio transceiver. Li Kongrong was disappointed and happy at the same time, disappointed that he did not extort the Germans again, and happy that even if he encountered the British Royal Navy, the Germans' passwords would not be leaked because of themselves.

The diesel engine roared constantly, and the U-38 submarine sailed at full speed on the Baltic Sea in the dark night, and the waves from time to time flooded her deck, and even hit the enclosure, stirring up waves, and the sea breeze poured the salty taste of the Baltic Sea into the submarine, which made everyone excited. At two o'clock in the morning, the submarine sent a telegram to the receiving merchant ship cruising off the coast of Denmark as planned.

"Zunzhi, they're out!" Gao Guangyou, who was the first to see the message, trembled excitedly, and he read the short message three times before informing Lin Zhun and the others.

"Really out?" Lin Zhun and others, who had been waiting for news, grabbed the message. The theft of an active German Navy submarine from a German shipyard seemed impossible to them, but it was unbelievable that it actually worked.

"It's out." After reading the message, Lin Zhun handed it over to Lin Xiangguang and the others, he calmed down and said, "Everyone go and rest first, and we will meet them in four hours." (To be continued.) )
