Imperial Overlord

In the next second, he realized what was going on on the sea in his mind.

The German navy has its own tactics. In 1940, although it was not too mature, the wolf pack tactics had already formed its own prototype under the insistence of Dönitz.

This immature tactic allowed the German Navy's submarine force to find and attack as many Allied transport ships as possible.

The wolf pack tactics are not complicated, to put it simply, it is communication and cooperation. This system focuses on the discovery-ambush coordination process.

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

The first submarine to spot an enemy convoy, was on a mission to follow and confirm its course and position.

Because of its speed, it may not have a chance to find an attacking position, but this submarine that finds the enemy will transmit its findings to all the surrounding submarines by radio.

The rest of the submarine force will rush to the route of the Allied transport fleet in advance, ambush and team up to attack the Allied transport.

Because submarines attack in groups, theoretically, they will achieve greater results, and they can also disperse the enemy's anti-submarine energy to counterattack, so the results will be more obvious.

This tactic is very similar to the way wolves are attacking their prey, so it is called "wolf pack tactics". In fact, this may be a conceptual prototype of the most primitive maritime saturation strike theory.

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

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

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

So at the beginning of the attack, you still have to rely on the submarine to play by itself, and the attack scene will become chaotic.

Although wolf pack tactics are still crude, they are not as fluid and immediate as the inter-service coordination in modern warfare.

But after all, this is a new tactic that leads submarine warfare, and it is still very powerful in the face of the British fleet with insufficient anti-submarine capabilities.

Apparently, in the other direction, another German submarine was also attacking, and the attack time of the two was almost the same.

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

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

So when Prien heard the seventh huge explosion, he understood that he might have been involved in a wolf hunt without knowing it.

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 got before was not the basic procedure of the wolf pack tactics.

If it was an order from a lair, there would often be clear coordinates provided by a reconnaissance submarine, rather than a course.

In the same way, if it is the habit of attacking from wolves, the submarines that were besieging the prey before will use radio communication in advance, and it is quite frequent.

It was this telegram from the submarine headquarters that made Priyan forget the wolf pack tactics. Obviously, this telegram did not conform to the combat habits of German submarines.

"Maybe it's because the matter is more urgent, because I got this important information, so I have to send it directly to me..." Prien convinced himself in his heart.

He raised his head and asked the officer beside him, "How are the torpedo preparations? If the preparations are complete, let's see what the British mess up."

Beside Prien, the first officer also thought of the situation on the sea, smiled and nodded and said, "The report is good! The torpedo is ready! You can go up at any time!"

"Very good!" Prien nodded, then grabbed the armrest beside him, and gave the order: "Float up to the height of the periscope! All are there, keep fighting, and be ready for battle at any time!"

"Starting ascent!" Not far away, the non-commissioned officer in charge of the drainage valve unscrewed the upper handle, and the submarine began to float up from a depth of 40 meters with a slight tremor, as nimble as a giant shark.

"Depth 30! ... 25!" Looking at the value on the pressure gauge through the dim light, the officer next to the drain valve reported the number he saw again and again.

"15 meters deep!" He slightly twisted the valve in his hand to slow down the speed of the water drainage, and the vibration of the submarine became weaker, and everyone began to feel the familiar shaking again.

There are no swaying waves in the 40-meter-deep sea. The silence there is like stagnant water. If it does not encounter undercurrents or special areas, there will be no obvious swaying.

Now I can feel the obvious shaking, which proves that the place where the submarine is located is not far from the sea.

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

Soon, the submarine stopped at the depth he wanted. German submarine officers and soldiers are probably the most well-trained soldiers in the world, and they are no worse than special forces.

You must know that among the 40 submarine officers and soldiers, there must be professional mechanical repairers, cooks, navigators, radio operators, and even blasting experts.

Don't think this is an alarmist, just find a few photos of the interior of the submarine, and you can understand why they are so worthy of respect.

Therefore, these officers and soldiers are absolutely meticulous when 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 stopped at the periscope depth of 10 meters, Prien ordered, while sticking to the eyepiece of the periscope, trying to look down on the surrounding situation.

When his periscope came out of the water, he couldn't help being surprised when he saw the lines of the transport ship outlined by the moonlight on the pitch-black water.

Originally thought it was the moon in the sky that illuminated the surrounding waters, but soon he found the wreckage of the burning and exploding transport ship around him.

The nearest 6,000-ton transport ship has been broken in two, and the bow has been raised high.

Farther away, a freighter had capsized, and not far from the overturned freighter, a transport ship of almost 8,000 tons was sinking.

"Continue to surface!" Prien hurriedly ordered, it seemed that all the German submarines were preparing for the second attack, and it was a very dangerous thing to continue to stay at a diving depth of 10 meters.

You must know that when attacking the freighter, the German torpedo was set at a depth of about seven or eight meters, which was just enough to hit the person who dived at a depth of 10 meters.

Therefore, when German submarines attack, they like to float on the water, because doing so can also avoid accidental damage from their own torpedoes.

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

"I'm going up! I'm draining!" Soon the U-47 submarine's not so huge upper hull was exposed to the surface, the diesel engine was roaring happily at this time, and the electricity in the submarine also began to be sufficient.

The lights are obviously bright, and everything around is no longer so dim. At this time, Prien also found his next target to attack.

"The left rudder is full! 27 degrees!" He loudly ordered his subordinates~www.readwn.com~ to make his submarine aim at the huge target with the bow as soon as possible.

Because the torpedoes were launched before, the attack angle and spacing of the torpedoes can be set in advance by taking advantage of the hidden sneak attack, so the bow of the submarine does not need to be completely pointed at the target.

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

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

"No. 1 and No. 2 torpedo tubes! Get ready!" While he aimed his submarine at the target, he nervously used a periscope to observe the surrounding movement.

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

Chaos is the greatest chance for German submarines. There was already a smile on the corner of Prien's mouth, and it was time for him to show his talents.

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

"Tom! Tom!" Different from the underwater launch, with two dull sounds, two slender torpedoes were ejected from the torpedo launch tube in front of the submarine, smashing through the water in front of the submarine.

The splashing waves hit the bow of the submarine, which extended all the way to the radio antenna on the mast on the hull, and the sea was still dripping down at this time.

Under the darkness of the night, the tiny figure of the U-47 submarine, against the backdrop of the fire, looked even more ferocious.
