In the next second, his mind realized what was going on on the sea. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The German Navy had its own tactics, and in 1940, although it was not too mature, the wolf pack tactics had already taken shape under Dönitz's insistence.

This less sophisticated tactic allowed the German Navy's submarine forces to find and attack as many Allied transports as possible.

Wolf pack tactics are not complicated to say, to put it simply, communication and cooperation. The system focuses on the discovery-ambush process.

Normally, Dönitz had his submarines deployed vertically along the routes that the Allies might pass, ensuring that the probability of spotting the enemy's transport fleet was greatly increased.

The first submarine to spot the enemy's transport fleet was tasked with following and confirming its course and position.

Because of its speed, it may not have a chance to find an attack position, but this submarine that discovers the enemy will radio the situation of its discovery to all the submarines around it.

The remaining submarine forces would rush to the route of the Allied transport fleet in advance, set up an ambush and attack the Allied transport ships.

Because the submarine group will attack it in theory, it will achieve greater results, and it can also disperse the enemy's anti-submarine counterattack, so the results will be more obvious.

This tactic resembles a pack of wolves attacking their prey, so it is called "wolf pack tactics". In fact, this may be the conceptual rudiments of one of the most primitive theories of saturation strikes at sea.

Prion knew this tactic, but he rarely used it, and in fact in the spring of 1940, as an ace captain, he was mostly a lone ranger.

However, he had also participated in this kind of operation, so he reacted immediately, and there must be submarines of his own people attacking around him.

The wolf pack tactics cannot achieve real-time communication during the battle, but can only achieve pre-war coordination and scheduling.

Therefore, at the beginning of the attack, it is still necessary to rely on the submarine to play on its own, and the attack scene will become chaotic.

Although the wolf pack tactics are still brutal, they are not as fluid and immediate as the coordinated operations between the branches of the military in modern warfare.

But after all, this is a new tactic that has led to submarine warfare, and its power is still very strong in the face of the British fleet, which lacks anti-submarine capabilities.

It is clear that in the other direction, another German submarine was also attacking, and the time of the attack was almost the same for both.

This is the benefit of the high quality of the front-line troops and the good habit of carrying out orders. In the vast sea, the German naval officers and sailors can still be as accurate as clocks, which is absolutely commendable.

In fact, Prien underestimated Li Le's determination to destroy the British sea supply lines, and at this time, around the British J-18 transport fleet, three German submarines were attacking.

So when Prion heard the 7th loud explosion, he realized that he might have unknowingly participated in a wolf hunt.

If the wolf pack tactics were followed, Prien would have known that there were other German submarines around.

The reason why he didn't immediately realize that there were other German submarines involved in the attack was because the telegram he had obtained earlier was not the basic process of wolf pack tactics.

If it is an order from the lair, there will often be clear coordinates provided by a reconnaissance submarine, and not a route.

Similarly, if it is a habit of attacking from a wolf pack, the submarine that has surrounded its prey before will use radio contact beforehand, and it is quite frequent.

What made Prien forget the wolf pack tactics was this telegram from the general command of the submarine, which obviously did not correspond to the combat habits of German submarines.

"Maybe it's because it's urgent, and because I got this important information, I had to send it directly to me......" Prion convinces himself in his mind.

He raised his head and asked the officer beside him: "How is the torpedo prepared?" If we are ready, let's see what happened to the British. ”

Prien's side, the first mate also thought of the situation on the sea, nodded with a smile and said, "Report to the chief!" The torpedo is ready! Float at any time! ”

"Good!" Prion nodded, then grabbed the handrail beside him and gave the order: "Float to periscope height!" All of them, stay in battle shape and be ready to fight at any time! ”

"Float begins!" Not far away, the non-commissioned officer in charge of the drain valve unscrewed the upper handle, and the submarine began to float from a depth of 40 meters with a slight tremor, nimble like a giant shark.

"Depth 30! …… 25！ In the dim light, looking at the values pointed to on the pressure gauge, the officer at the drain valve reported again and again the numbers he saw.

"15 meters deep!" He twisted the valve in his hand slightly, slowing the drain, the submarine's tremor became faint, and everyone began to feel the familiar shaking again.

At a depth of 40 meters, there are no wobble waves, and the silence there is like stagnant water, and there is no obvious shaking if you do not touch an undercurrent or a special area.

Now a noticeable shaking is felt, proving that the place where the submarine is located, is not far from the surface of the sea.

"Stabilize the submarine! Keep it at a depth of 10 meters! Prien's hand removed from the armrest, pressed it on the handle of the periscope, and commanded.

Soon, the submarine stopped at the depth he wanted. The German submarine officers and men were probably the most well-trained soldiers in the world, and they were all better than the special forces.

You must know that among the 40 submarine officers and men, there must be professional mechanics, cooks, navigators, radios, and even blasting experts.

Don't think this is alarmist, just take a few photos of the inside of the submarine and you'll see why they deserve so much respect.

Therefore, these officers and soldiers are absolutely meticulous in carrying out orders and uniting and cooperating, otherwise they will sink to the bottom of the sea and will not live tomorrow.

"Raise the periscope!" When the submarine naturally stayed at the periscope depth of 10 meters, Prien gave the order while sticking to the eyepiece of the periscope, trying to look down on the surrounding situation.

When his periscope came out of the water and saw the lines of the transports outlined by the moonlight on the dark water, he couldn't help but be surprised.

He thought it was the moon in the sky that lit up the surrounding sea, but he soon spotted the wreckage of a burning and exploding transport ship around him.

The nearest transport ship, about 6,000 tons, had broken in two, and its bow had been raised high.

Farther away, a freighter had capsized, and not far from the capsized freighter, a transport ship of almost 8,000 tons was sinking, and the fire on board could not be rescued.

"Keep afloat!" Prien hurriedly ordered, it seems that all German submarines are preparing for a second attack, and it is a very dangerous thing to continue to stay at a depth of 10 meters.

You must know that when attacking a freighter, the fixed depth of the German torpedo was about seven or eight meters, which was just enough to hit one's own people at a depth of 10 meters.

Therefore, when German submarines attacked, they liked to float on the water, because they could also avoid accidental damage from their own torpedoes.

Because the tonnage of German submarines was less than 1,000 tons at this time, the draft was within a very safe range.

"I'm on the top! Draining! Soon the U-47 submarine's modest upper enclosure was exposed, the diesel engine was roaring happily, and the power inside the submarine was beginning to be sufficient.

The lights were noticeably brighter, and everything around them was less dim. And at this time, Prion also found his next target.

"Left full rudder! 27 degrees! He shouted orders to his men to aim their submarines at the huge target with the bow as quickly as possible.

Because the torpedo was fired before, the attack angle and spacing of the torpedo could be set in advance by taking advantage of the covert sneak attack, so the bow of the submarine could not be completely pointed at the target.

However, the fish that are loaded into the bow launch bay of the submarine are all set of direct fire, which is the usual practice of the German Navy, and it is also the safest setting for sneak attacks at night.

In this setting, the torpedo can accelerate faster and rush to the target at a faster speed, but the disadvantage is that the range is very close and can only be used at close range.

"Torpedo tubes No. 1 and No. 2! Get ready! He aimed his submarine at the target while nervously observing the movement around him with his periscope.

Obviously, the British transport fleet did not anticipate such a massive attack on itself. They were very flustered at this time, and because there were too many places to be attacked, the surrounding anti-submarine warships could not confirm which direction the attack came from for a while.

Chaos is to give German submarines the greatest chance. There was already a smile on Prien's lips, and now was the time for him to show off his skills.

"Aim for the target! Torpedo tubes No. 1 and No. 2, launch! He stared at the unconscious behemoth in the distance and gave the order to attack.

"Tom! Tong! "Unlike underwater launches, with two muffled sounds, two slender torpedoes erupted from the torpedo tubes in front of the submarine, crashing through the water in front of the submarine.

The splash of the waves hit the bow of the submarine, which stretched all the way to the radio antenna on the mast on the enclosure, which was still crackling and dripping with seawater.

Under the darkness of the night, the small figure of the U-47 submarine looked even more hideous against the backdrop of the firelight.
