"Captain, we have reached the marking point."

Deputy Captain Lieutenant Kathelin recorded the current boat seat on the chart and reported it loudly to Gisel.

"Very good, prepare to turn, head 240, maintain the current depth and speed. We will be able to leave the current patrol area in another half an hour. I hope we won't have to have such a long snorkeling before entering the French waters." Gisele answered leisurely in his captain's mat with a cup of coffee.

"As for orders, captain. prepare to turn, head 240." Kathellin retold Gisel's order loudly: "In five seconds, start turning, 5.4.3.2.1, turn... Report to the captain, turn is completed. Now heading is 240."

"very good."

Gisel was very satisfied with his good training, and then he picked up the inside phone hanging on the reinforcement support beam of the command cabin and then adjusted the lever to the listening room.

"Corporal Wolfgan, I am the captain, report the current situation. Are they still following?"

"They were still following behind, with less than 1,500 meters apart on both sides of the stern, and the sound of the spiral was clear and loud. U38 and U43 were not behind, sir."

"Very good, keep monitoring, and you must report any abnormalities to the command module immediately."

"As for orders, sir."

Gisel put down the phone with satisfaction, turned his head to Kathelin and said, "We have now entered the waters where the enemy ships are very active. I hope we will not encounter any trouble. Now any mistakes in our world may cause irreparable losses to Germany. Marshal Reinhart must be sent to France safely."

"I understand, Captain. All of us understand this, don't worry." Kathering replied with a serious expression.

"Very good." Gisele smiled and nodded.

"Report to the captain."

The deputy navigator of u37, Lieutenant Turk, hurriedly entered the command cabin, and before he could stand up, he hurriedly reported loudly: "Marson, please come and see him immediately if it is convenient now."

Gisele frowned when he saw Turk's panic look, but when he heard that it was the Marshal who wanted to see him, he didn't care about blaming his subordinates for his abnormal reaction. Gisele hurriedly asked Turk: "Where is the Marshal now."

"In the torpedo compartment."

"Okay, I'll go there right away." Gisele turned around and said to Catherine, "Kisel, I'll leave it to you now. If you have any questions, please notify me immediately."

"Don't worry, captain."

Gisele looked around, then quickly got out of the command cabin and walked quickly towards the first torpedo cabin. Turk hurriedly followed.

"Turk, why did the Marshal go to the torpedo cabin? Isn't he chatting with you?"

Before the two commandos passed through the command cabin to go to bed, they reported to Gisel that the marshal had woken up and was walking in the boat. Then another sailor came to report that the marshal was chatting with several officers in the rest area. Now the marshal had actually gotten into the torpedo cabin again. Gisel could not figure out what the priest was thinking.

"We were chatting, but just after we accidentally talked about those failed attacks, the marshal suddenly wanted to go to the torpedo cabin to check it out, and we didn't dare to stop him. Now the gun captain and the mine captain are accompanying him."

"Failed attack? You mean the attacks we had on our last cruise."

"Yes, Captain. Marshal said he might know the reason for the torpedo failure."

"What, the marshal really said that." Gisele's steps were stagnant.

"Yes, that's what he said."

"Oh." Gisele pondered for a moment, then accelerated his pace towards the torpedo compartment.

Now the corridor of the front cabin is full of sailors and low-level officers. They are curiously looking into the torpedo cabin and talking to each other in a low voice. When they see the captain walking quickly, the people quickly stood at the wall and gave up a passage for Gisele.

When Gisel got into the torpedo compartment, the first thing he saw was a T3 placed on the torpedo loading rack in the center of the torpedo compartment. Now this 533 mm caliber weighing 1,600 kilograms has been removed. From the unloaded inspection ports, the components coated with lubricating and anti-rust oil on the inside of the torpedo were shining with dark golden light under the bright lights in the cabin.

"Marson, you came to me just to let me see this." Gisele walked to Xu Jun, who was standing next to the torpedo and carefully watched the torpedo chief work, and asked respectfully: "My Marshal, have you really discovered the reason why our torpedoes often fail?"

"I'll talk to you later, wait a moment, and there will be a result soon."

Xu Jun turned his head and looked at Jisel first, then focused his attention on the current work of the torpedo chief Sutton.

Sutton, the mine leader of the u37, was holding a screwdriver to remove the panel on the inspection port of the torpedo balance cabin. When the small steel plate was removed, a small air hole was exposed. Sutton quickly took off a pressure gauge from the tool holder beside him, and then carefully inserted the air hole.

"What is Sutton doing? Is it measuring the pressure of the balance cabin? This won't do anything. The air pressure of the balance cabin has been tested on land, and there is no problem." Gisele felt that the Marshal was an army officer and was not very familiar with the weapon of torpedo.

"Don't worry, my captain, keep your patience, the result will be announced soon." Xu Jun said to Gisele with a smile.

"Ah? Why is this happening!" Sutton, who was carefully observing the pressure gauge reading, screamed.

"What's wrong?" Gisele hurriedly came over.

"Captain, it seems that the Marshal's guess is correct. Look at this reading. The pressure in this damn balance cabin is now the same as the pressure in our boat."

"What, there is such a thing. This is impossible." Gisele looked carefully at the reading on the pressure gauge, then turned his head to look at the reading on the pressure gauge on the boat wall. He was stunned by what was happening in front of him.

"The torpedo's depth is entirely determined by the air pressure of this balance cabin. We all set the torpedo submersible depth based on the pressure of maintaining an atmospheric pressure in the balance cabin. But the pressure of this torpedo is the same as in the boat, which means that if we still set the depth of this torpedo as written in the cāo manual, its actual depth will be much deeper than the depth we set, and it may be three to five meters apart, and it may be even more." Sutton said with a frown.

"That means we can't hit the target with this torpedo." Gisele said suddenly: "It turns out that the torpedo we shot did not fail, but all of them crawled through the bottom of the enemy's ship."

"It's very likely that this is the case. It seems that we are actually shooting at the bottom of the sea." Sutton shook his head and sighed.

"Can you make a mistake during the inspection, such as the balance cabin being accidentally opened and sealed." Gisele was scared when he thought that his torpedo might have this problem, which means that he would not have a useful weapon to protect himself during this voyage.

"There is absolutely no problem. I did it strictly according to the land inspection procedures." Sutton replied firmly.

"Gentlemen, let me say a few words." Xu Jun inserted lightly on the side.

It was only then that the two naval officers realized the existence of the marshal. It was then that they remembered that this question was discovered entirely by the marshal's proposal. They now hoped to get the correct answer from the soldier who was constantly creating miracles. Gisele and Sutton quickly stopped the discussion. They looked at Xu Jun with breath and focused, waiting for him to express his opinion.

"We now know that there is a problem with the balance cabin of this torpedo, so have you ever thought about why this situation happened?" Before the two people answered Xu Jun, they continued: "There is only one reason for this situation, that is, the balance cabin has lost its seal. I think it is more likely that it has never been sealed. This shows that the reason why German torpedoes often fail in actual combat during this period. In the past period, the failure of torpedoes often occurred after you had been submersible for a long time, and at that time, the submarine was in the submarine.

The pressure in the part will increase a lot, and because the balance cabin is not sealed, the pressure in the torpedo increases with the air pressure inside the submarine. As a result, as Second Lieutenant Sutton said, all our torpedoes were shot to the seabed. The torpedoes launched in the water surface state can hit the target reliably because the air pressure is the same as the outside world. Including those with short submarine time or floating and ventilation, their torpedoes remain in an effective state due to normal pressure inside the boat. This is why the torpedoes sometimes fail without any faults and sometimes fail."

"It seems that you are right, my marshal. You are really an apostle of God." Gisele stood up and saluted Xu Jun respectfully.

"I would like to express my sincere thanks to you for all the personnel of the German Submarine Force."

"Ah, no need to do this. I just heard your subordinates talk about this matter and suddenly thoughts popped up in their minds. I think the problem may be due to the torpedo's concentration, so I took the initiative to do this test. If you want to say thank you, you have to thank those officers for asking me about this." Xu Jun felt a little embarrassed when he heard Jissel's thanks. In fact, he had learned about the problem of German torpedo from previous historical materials. Now he is obviously plagiarizing the labor achievements of those German scientists. He put this credit on himself, even if Xu Jun's skin is tough, it feels hot.

"Please don't say that, my marshal, if it weren't for you, I really don't know how long our submarines would fight with such unreliable weapons. You know the efficiency of those people in the Naval Ordnance Bureau." Gisele said excitedly.

"Haha, let's not talk about this. This is a reward for your care for us army officers. Well, since we have found the problem, we can come up with countermeasures. At least this weapon can still be used. Second Lieutenant Sutton can now reassemble it."

Xu Jun wanted to change the topic, but Jissel obviously did not want to do so. He no longer knew how to express his mood. Xu Jun's discovery helped a large number of submarine captains, including him, to restore their reputation. Now they can finally prove that the failed attacks were not because of their personal technical problems, but because the damn torpedoes were useless.

"My Marshal, I think your reward is too expensive. You must know that you have saved half of the navy's submarine captains. You have opened the road for them to regain confidence. You must know that there are several excellent submarine captains who have doubted themselves because of several failed attacks. Your discovery saved them, to be precise, you have also saved the lives of countless submarine soldiers. In the future, no one will lose their lives because of a broken torpedo. This has happened many times. Several submarines were attacked because the torpedo not only failed to hit the enemy ship but also exposed their positions. I believe that everyone will be very happy when they know this problem. My Marshal." Gisel could not hide his joy.

"Haha, my captain, I said this was just my momentary inspiration. I didn't do much for you, so stop saying that." Xu Jun said with a smile: "Now we know the problem, but we can't solve it immediately. We have to continue to use it before improving the torpedo. So I think we have to come up with a way to use it effectively. After all, it is a problem of fixed depth. I think it's enough to reduce the fixed depth accordingly after testing the pressure in the cabin. The magnetic fuse doesn't seem to be very reliable, and without accurate fixed depth, it has no effect. I think it's simply turned off all of them and wait until the more reliable product is fixed before considering it. Look at it, you can notify the other two submarines to do this when we float to the surface."

"As for the order, my marshal, everything will be carried out according to your will." Gisele replied respectfully: "Please leave here first and go to the officer's room for a rest. The air here is too turbid, and there are greasy and debris everywhere. This... is really..."

"Oh, that's it, okay, then I'll go to the officer's room for a while. Can you please make some food for me? I'm a little hungry." Xu Jun said to Gisele as he walked out of the cabin.

"As for orders, my marshal, I will arrange it right away."

At this moment, the telephone on the torpedo bulkhead suddenly started to scream. Gisele quickly picked up the receiver and said, "Torpedo cabin, I am the captain, what's the matter? What, are you sure? How many... I'll come over right away."

Gisel's face became increasingly ugly as the report on the phone became, and the excellent submarine captain had a nervous look on the face for the first time. Xu Jun stopped and looked at the captain. He noticed a hunch of uneasiness in Gisel's tone and expression. Something must have happened, and this matter must be very, very troublesome.

"What happened, Captain." Xu Jun looked at Jisel with a worried look.

"It's not certain yet. My Marshal. Let's go to the command cabin first, so I can get a detailed report there. If you're right, we're in great trouble now. Marshal, please come with me." After saying that, Gisele hurriedly walked towards the command cabin.

The soldiers and officers surrounding the door also felt something had happened from the captain's expression. They stood quietly on both sides of the aisle to make way. When the captain passed, they would automatically walk towards their respective posts. If they really encountered a battle, those posts would need manpower. Suddenly, with a few sharp battle reports, the lights in the submarine were suddenly switched to red combat lights. The crew members were excited all of a sudden, and everyone stood in their respective combat posts, looking firmly at the speakers in their respective cabins. They were waiting for the captain to give their instructions, and they also wanted to know what kind of enemy they encountered this time.

The entire submarine was instantly shrouded in an extremely solemn atmosphere of depression before the battle, and the hot murderous aura spread throughout every corner of the u37 with the breath of the crew.

The crew believed that as long as they obey Captain Gisel's command, they could easily overcome any difficulties. What's more, there is a German war god on the boat, the apostle of God. Under the protection of this miracle creator, they might have made some legendary achievements. So no one of these sailors felt nervous or afraid. On the contrary, they began to look forward to the next battle. They all had a premonition that it would definitely be a fierce battle, a wonderful battle, and more likely a battle that would never be forgotten for the rest of their lives, allowing them to tell others about their lifelong battle.

In the early morning of June 26, 1940, a brutal sea battle was about to begin in the empty waters 80 nautical miles off the Norwegian coastline. A group of elite German sailors were eager to prove their bravery with blood and fire, and they were going to extract their medals and glory from the blood of the enemy.
