After sinking three aircraft carriers, considering that it was difficult for battleships to be blown up, the French Air Force turned the spearhead to British cruisers and destroyers, but they had just sent a destroyer that had been damaged by "mistakenly hitting the auxiliary vehicle" during the previous bombing of aircraft carriers to the bottom of the sea, and the British battleship Sovereign suddenly rose with billowing smoke without being attacked by French bombers, and Vice Admiral Somerville, who had just transferred to the battleship King George V, had not yet figured out what was going on. I watched this battleship with a glorious history quickly sink into the sea

It wasn't until the Sovereign sank completely that Vice Admiral Somerville thought of a possible cause, "Could it be a torpedo fired from a submarine?" Didn't you hear of German submarine activity here? Could it be Italian? ”

Now that the fighting was fierce, it was impossible to spare much liliang to devote to anti-submarine operations, and Vice Admiral Somerville had to ask the ships to be careful with torpedoes while activating active sonar for detection. The effective detection distance of the active sonar of the submarine in this period was less than 3 km, but the torpedoes fired at a distance of 3 km were enough to allow enough reaction time for each ship. But not long after Vice Admiral Somerville's order was given, the British battleship Revenge followed in the footsteps of the Sovereign, and Somerville was almost mad, clenching his fingers and subconsciously grasping his hairstyle, which he had always paid great attention to, and cried out in his heart, "Oh God! Tell me what the hell is going on? ”

The attack on the "H" flotilla was not the Italian submarine that Vice Admiral Somerville had thought, but the German submarine that he thought was impossible. At this time, Germany's submarine base in France had not yet been built, but because of Hu Weidong's suggestion, Dönitz still sent a small number of submarines into the western Mediterranean Sea in advance to "explore the way".

At that time, the crew of the U-boat saw the columns of smoke rising from the sea level through the periscope, and immediately realized that there was a naval battle, and the scale was very large, and through the changes in the columns of smoke, they judged that they were approaching their side, and the captain Moore immediately decided to ambush the opponent's forward side to try his luck, if the opponent was an enemy warship and the battle continued when it drove there. He just took the opportunity to fish in troubled waters. sneak attack; And if it's a friendly fleet, or if the battle is over when you get here, then forget it, a submarine attacking a large fleet, even if you can achieve results. He will definitely die under the other party's dragnet search. He didn't do this kind of stupid thing.

As a good submarine commander. Captain Moore is well aware of the weakness of his U-boat, which is too slow underwater and cannot quickly move away from the target in the submersible state, as long as the opponent has enough warships with anti-submarine capabilities. If you spread out and turn on the active sonar to eliminate area by area, you can always find yourself, and if the other party still has an aircraft, it will be even more difficult for the submarine to escape.

Thinking of this, Captain Moore looked forward more and more to the new submarine in the shape of a teardrop, and His Excellency Admiral Dönitz had promised them that when the first batch of new submarine cadets graduated and were able to take over the responsibility of submarine warfare, they would be able to terminate their mission and return to China for training

Although he had complained for a long time about the low underwater speed of the U-boat, it did not have much effect if he waited for the rabbit, and because of the deep sea in this area, the boat was equipped with every German submarine captain's favorite - an improved version of the oxygen torpedo, which not only had a long range, high speed, and great power, but also had almost no track when sailing, and it was difficult for those large ships to effectively avoid it even if it was immediately recognizable to the naked eye.

For the same reason, it is also difficult to give early warning to destroyers on perimeter alert, unless they happen to be in the way of torpedoes (due to the huge losses in the Battle of Dunkirk [the number of destroyers that were sunk was already quite large, and many more destroyers had to be maintained because they were injured or overused [mainly anti-aircraft guns]). This time the British did not send enough destroyers to basically not be able to do this. And a sneak attack when the other side is busy fighting, not to mention the effect

Out of the necessary caution, Captain Moore selected three big guys just after the target distance of 3000 meters, and released 2 torpedoes to each of them, and the result was lucky, because the distance was close enough and it was relatively sailing, the first 2 torpedoes all successfully hit the target, the oxygen torpedo was already more powerful than ordinary torpedoes, and it only sailed less than 2000 meters (the torpedo and the battleship were opposite to each other) to hit the target meant that the liquid oxygen it carried only used up a little, The remnants of a large amount of liquid oxygen further increased the power of the torpedo explosion, and after the two torpedoes hit, they directly sank the battleship Sovereign, which had a full load displacement of more than 30,000 tons, and almost all the warships were buried before they could evacuate

In the next four attacks, the hit rate dropped sharply as the alert British warships began to change direction, but one torpedo still hit the battleship Revenge, and although the officers and men on board tried their best to save it, the old battleship finally sank to the bottom of the sea

The elated Captain Moore and his men were eager to continue the battle, but it would take a long time for the torpedo to be reloaded, and since it had been many days, most of the fuel and supplies on the ship had been used up, so they had to sail back to the mainland to replenish and report to the commander and the Führer. Overjoyed to learn of their miraculous victory, Mustache personally awarded Major Moore the rank of Major and the newly established Knight's Iron Cross with Silver Oak and Sword, making Captain Moore the first recipient of the medal on this plane. The outstanding performance of a group of outstanding submarine officers and men, including Captain Moore, also made the mustache fully aware of the great power of submarine warfare, and immediately approved Dönitz's proposal to expand the scale and scope of submarine warfare.

At this time, Germany had already trained some qualified submariners who could skillfully control the drop-shaped submarines, and also built the first batch of four drop-shaped submarines with actual combat capabilities, but most of these learning backbones were retained as instructors by the submarine school, and the four drop-shaped submarines were also handed over to the submarine school for teaching. Only after the first batch of new submarine trainees of the submarine school graduates and the number of equipment for the drop-shaped submarine also increases, will this new-type submarine that is beyond the times get the opportunity to show its skills. Otherwise, piecemeal fighting will not achieve much success, but will give the enemy more time to study ways to deal with it. However, even with those old-fashioned U-boats, Dönitz believes that he can still achieve good results with his "wolf pack tactics" (to be continued......
