"First depth charge!" With a roar, the Soviet destroyer dropped the first depth charge of the day to attack a submarine. After an hour of dogfighting, for the first time, the Soviet destroyer felt confident that it could sink its opponent, so it launched a fierce attack.

Just an hour earlier, the destroyer had turned with Prien's submarine and then sailed along a course for another 2 minutes, only to suddenly lose track of the submarine. With a little calculation, the bearded captain guessed Prien's trick - slow down.

In fact, the speed of the opposing submarine is decreasing after adjusting the course, and the destroyer sonar at this time is deployed in front of the hull, that is to say, the rear of the destroyer is actually a sonar blind spot.

Using this principle, the German submarine cleverly hid in the sonar blind spot of the Soviet destroyer. This is also a trick learned from the British Navy, if submarine warfare in Britain taught the British how to anti-submarine, then how many British captains learned anti-submarine warfare, how many German submarine captains have practiced the ability to escape from the tiger's mouth. The nature of war is that you come and go, and no one stipulates that only one side can grow in war.

However, the destroyer relied on its high speed to seize the initiative, and after half an hour of circumparation, just when Prion thought he was free from the Soviet destroyer's entanglement, the bearded man returned to the battlefield with his strong obsession for revenge.

Prien was really tormented crazy by this haunting fellow, and the last time he had such an experience was after the sneak attack on Scapa Flow, when the British Navy searched for it overwhelmingly. But it was the terrible process of being intercepted by dozens of ships in front and back, and being chased by a destroyer like this, it was the first time in Prien's life.

So a new round of hunting began, and this time the process was much more thrilling than the last, because when the bearded man re-found Prion with his destroyer, his course control was not so good.

Captain Prion on the submarine came up and gave the bearded man a weighty greeting gift: he fired two torpedoes with a torpedo tube in the tail, directly disrupting the beard's pursuit. The destroyer was forced to dodge the oncoming torpedoes and once again lost its target. This also proves Prien's mood in another way, and submarine commanders are generally reluctant to use valuable torpedoes to get rid of the opponent's anti-submarine attack.

The poor Soviet destroyer had to once again predict where the submarine was located, and once again grabbed Prien's tail. But this time Prion played zigzag sailing again, because during this time, Prien's submarine had risen to periscope depth, ignited the diesel engine and filled the battery with power. So this time, Prien was even more daring to play a game of hide and seek with the bearded destroyer. The submarine picked a relatively safe sea area and dropped to a depth of 70 meters, which is already a depth that is not easy for destroyers to detect and attack, and as the depth increases, the positioning of the submarine becomes even more difficult.

However, after an hour of entanglement, the bearded captain did not want to dwell any further, and he gave the order to attack, and the first depth charge was finally dropped into the water by the bombardier.

"The other side is attacking! Depth charge!" The sonar soldier heard the strange sound of things entering the water, and hastened to report the news he had received: this sound was all too familiar, because this destroyer was built in England, and the German submarine force of the same type of escort destroyer had encountered it almost several times.

"Right rudder, dodge this bomb! After the explosion, give the Soviets the prepared gifts, then turn off all systems and wait for them to leave!" Prion decided to take out the killer weapon that he had been preparing for an hour. He asked the soldiers to remove a bunch of useless wooden planks and life jackets from the submarine, and then loaded them into torpedo tubes.

All he had to do now was match the explosion of the opponent's depth charges, launch the debris, and then let the stuff surface, creating the illusion that the submarine had been hit and sunk. This trick can be described as an Oscar-winning actor-level acting, and under normal circumstances, you can deceive your opponent and escape from Ascension - of course, this trick is also the last resort to save your life, and no one will use such an extreme method as cheating death to deceive your opponent.

And above the water, the bearded captain was also waiting, and he found the flaw of the German submarine captain a few minutes ago, which was the only flaw exposed by the other party in the process of more than an hour of wits and courage.

"This German opponent is really very cunning. If it weren't for our luck, we probably wouldn't have been able to sink this German submarine. The bearded captain stood on the bridge and sighed: "His only flaw is that he likes to do the left full rudder when he is the first to turn and maneuver! Subconscious habits make you doomed to die today." ”

He was confident in sinking his opponent, for he had just discovered Prion's habit by accident when he saw the incoherent and somewhat messy dots on the charts. He also deliberately confirmed it once, and found that the opponent did have such a small habit.

The depth charges that were dropped burst in the pitch-black ocean, setting off a huge air bubble, which expanded violently in the seawater, and because of the explosion, it expanded violently against the laws of nature. However, only a moment later, the surrounding sea water was squeezed back due to the tremendous pressure, forming a huge tearing force that vibrated back and forth. If a submarine is within the scope of this explosion, even if it is only a little bit, it will break and shatter because of this huge tearing force, and become a steel coffin underwater.

"Launch!" Prien's mouth slowly raised upward, and he couldn't help but feel a little smug in his heart - the flaw he deliberately exposed was finally discovered by the other party, using this attack, the shock from the huge explosion would greatly limit the other party's sonar work, and this was also the best time for him to escape from the pursuit.

Life jackets, planks, and other items were all pushed out of the sea by the high-pressure air, and some of these things began to float upwards at a rapid rate due to buoyancy. If the adversary sees these things, he will mistake the submarine for sunk and leave on his own initiative. To add to the realism of the effect, a pile of debris also includes a vat full of fuel, which will not surface, but will leak diesel fuel to make the shipwreck site look more realistic - an Oscar-winning scam, but not for nothing.

So, the quiet wait began, and the people inside the submarine waited motionlessly, waiting for the good news from the sonar soldiers. As the minutes ticked by, no one knew if the next second they would have the news of the enemy's departure over their heads, or if another deadly depth charge would fall.

The bearded captain was standing on the deck at this time, looking at the broken life jackets that clearly showed signs of friction, and the broken wood chips and planks. There are not many things that can surface on the submarine, and the most direct evidence is, of course, the corpse, but in this case, the corpse often does not surface immediately, and there will be no corpse.

"Wait and see!" the bearded man gave the order with a frown, and the destroyer cruised back and forth in the nearby waters, refusing to leave. It seemed to be waiting for the German submarine to show its feet when it couldn't hold its breath, and it also seemed to be waiting for the evidence that it had sunk the other side to surface.

The submarine officers and men who were accustomed to the smell of the French perfume mixed with diesel fuel were unaware of the chaotic smell of French perfume mixed with diesel oil, and they just looked over their heads, waiting for the time when their warship would start its engines and sing again.

On the deck of the destroyer, the cold sea breeze whipped the sailors' clothes, and they also waited, staring at the surface of the sea for fear that they would miss something important, hoping that more direct evidence would appear there.

Seeing that the oil stains were getting bigger and bigger on the sea, the bearded captain also felt that the current situation was definitely that the opponent's submarine had been sunk by himself. "I won! I sank them!" he sighed, and then gave the order to return, and after a circle, the destroyer began to sail on the course from which it had come, not very fast, but not very slow.

"It's about 20 knots, and it's heading away. The sonar soldier whispered what he heard to Prien. Prien nodded, ignoring the muffled cheers behind him, and gave another order to the non-commissioned officer who controlled the power of the submarine: "Turn on the power plant, go at full speed, and keep the rudder on the left!"

The submarine's batteries were working again, the engine motors were turning again, the power inside began to recover, and in addition to the emergency lights, some of the lights were turned on by the crew. It's no longer so gloomy, as if all of them have returned to the world from hell.

"Or is it still the left full rudder?" the helmsman asked, looking at Prien, confused. In order to deliberately sell this flaw just now, he carried out several operations on the left full rudder, and this time he got rid of the enemy, what else did he want to do with the left full rudder?

Prion patted him on the shoulder and explained solemnly: "This opponent is not easy to deal with, I don't know how long this trick can deceive him, so this time we must be ready to fight at any time, and we can't be a little careless!"

After saying that, he confidently clenched his fists: Destroyer commander, I admit that you are indeed strong, but this time, no matter what, it was me who escaped and ascended to heaven! Unfortunately, I won!
