In fact, in addition to the fact that the Austro-Crème laid a large number of mines in the Strait of Otranto to prevent the main forces of the Entente from entering the Adriatic Sea to attack the Austro-Hungarian naval fleet, the Entente side also set up anti-sufficiency in the Otranto Strait.

There was once an Austro-Hungarian submarine named U-15 many times in and out of the anti-submarine blockade line, and sank Allied ships many times, this Austro-Hungarian submarine named U-15 in the two years of the outbreak of the war you sank a total of thirteen Allied ships, including four of the sunken Allied warships, two light cruisers, a destroyer and a troop transport, at that time there were 900 Italian soldiers on the troop carrier, and at this time the U-15 was hidden in the sea in front of the rabbit ready to wait, It was this U-15 submarine that the Chinese expeditionary fleet and the French fleet encountered.

At this time, the U-15 submarine was slowly sailing in the direction of the Chinese fleet and the French fleet at periscope depth, and there was no way, it was not equipped with a sonar system. If you want to investigate the sea surface situation ahead, the only way to do it is to extend the periscope out of the water to investigate, and the so-called periscope depth is just enough to extend the periscope out of the water to observe the sea surface situation in front of you. But the submarine is below the surface, if the enemy ships are relatively close. In December last year, the Austro-Hungarian destroyer Batalon discovered the periscope of the French submarine Monge, and immediately fired at the opponent with the ship's rapid-fire guns, and after the opponent suffered heavy damage, it rammed and sank the French submarine Monge.

The U-15 submarine captain Knight Trapp, who was staring intently at the two hazy huge silhouettes in the periscope lens, came to the conclusion based on his own judgment that they were two destroyers with a displacement of two thousand tons, and he couldn't help but curse: "Damn." How is it a destroyer and a light cruiser? Send a message to the rear fleet, tell them to hurry up, I'd rather deal with a battleship than a destroyer! ”

The submarine encountered the destroyer, and if the engine was not turned off and the submarine was stationary, it would be easy to be detected by the sonar system on the destroyer, of course, this was not the reason why Trapp didn't want to fight the destroyer, after all, he didn't know that the two destroyers in front of him were equipped with sonar systems, and the reason was that the destroyer was very fast. And the tonnage is small, and the small tonnage means that the volume is small and the length is short, at high speeds. It is very flexible, and unless the two ships are very, very close together, it will be difficult for a torpedo fired by a submarine to hit the target. After all, it takes a time process for a submarine to go from rising to the surface of the water capable of firing torpedoes and firing torpedoes at enemy ships, and the probability of being detected by enemy destroyers during this time is very, very high. It is important to know that torpedoes from this period did not have tracking devices.

"Yes, Major!" The second lieutenant in charge of communications agreed. Then the newspaper began.

"Helmsman, dive twenty meters!" There are still several nautical miles from the two battleships in front, and Trapp is not in a hurry, he ordered the helmsman, so as not to be discovered by the enemy ship after a long period of observation, and it is necessary to dive in time, but if you want to observe the enemy ship again, you must let the submarine rise again, there is no way, the submarine periscope of this period cannot be retracted, and can only be observed by adjusting the sinking and floating of the submarine.

Knight Trapp's periscope had limited vision, and he only observed a destroyer and a light cruiser directly in front of him, but he did not observe a light cruiser and a destroyer on the left and right flanks, and these ships were sailing in the direction of a nautical mile radius of his submarine.

After resting for a few minutes and taking a few sips of water, Trapp patrolled the torpedo tubes on both sides and turned back to the command module without finding any problems, by which time about ten minutes had passed.

Trapp, who returned to the command module, walked up to the periscope and shouted: "Ascend to periscope depth!" ”

"Yes, sir!"

The U-15 submarine slowly ascended, stopped at the periscope depth, but was still moving slowly, Trapp immediately used the periscope to observe, the situation in the lens surprised him, in addition to the previously discovered cruiser and a destroyer less than two nautical miles from the submarine, he also found that there were a large number of warships behind these two ships, each of these battleships was extremely large, large and small combined fifty or sixty, looking at the appearance of the battleships and the flags hoisted, he found that they were the Chinese fleet and the French fleet, This is the Chinese expeditionary fleet and the main French fleet, how did they get through the guò mine area?

"Shhh

"Ahh

Despite the attack, the Knight Trapp was very calm, he turned his head and observed the periscope again, the situation in the lens shocked him, so he turned the periscope in the opposite direction, and three light warships appeared in the camera, he couldn't help but gasp again, he realized that the submarine was discovered by the other party, and it was in a state of surroundment, he couldn't understand how the other party found his submarine so far away, his submarine had just risen.

I don't have time to think about it. He immediately yelled: "Dive, dive!" ”

"Knight. How much to dive? The helmsman asked.

"Damn, dive as deep as you can!" Trapp yelled in frustration.

The U-15 was lucky this time too. In the process of diving, the Huaguo expeditionary warship fired several more shots, and the shells exploded around the submarine, although the momentum was very loud, but the submarine was still not harmed, and there was no danger of diving to the lowest depth.

"Quick, turn around, let's go back!" Under Trapp's loud orders, the U-15 submarine began to flee in the direction of its own fleet after making a slow U-turn. Trapp also forgot to send a notice to his own fleet during the dive just now.

As a matter of fact, the reconnaissance planes of the Chinese expeditionary fleet had already discovered the main fleet of Austria-Hungary, consisting of four dreadnoughts and some cruisers and destroyers, which were rushing towards this side, and the reconnaissance planes also exchanged fire with the Austro-Hungarian maritime reconnaissance planes and shot down the reconnaissance planes of the opposing side.

On the battleship Huanghe, Shen Shoukun, who was dressed in a straight naval training uniform, was smoking a cigarette and observing the sea situation in front of him with a telescope. Shells kept exploding in a sea area.

At this time, the communications staff officer walked in with a paper clip and saluted: "Report to the general, our sonar system has determined that the enemy submarine is within one kilometer of the house, and just now our cruiser Golden Pomfret also discovered the opponent's periscope and carried out artillery bombardment. The enemy submarine has dived to the maximum depth below the surface and is turning around and fleeing in the direction of the main force of the opposing surface fleet! ”

Shen Shoukun waved his hand: "Got it." ”

After the communications staff officer left, the combat staff officer walked in with a Wen Jiàn clip under his arm and reported: "General Qiyu." All the carrier-based aircraft of our two aircraft carriers are ready to take off at any time to bomb the Austro-Hungarian fleet! ”

Shen Shoukun thought for a while and said, "Inform the French of the war situation." And tell them that we have locked on the approximate area of the enemy submarine. It is currently under siege! Orders: First, to order the French fleet to sail at maximum speed in the direction of the Austro-Hungarian fleet at a distance of more than five nautical miles from our fleet, and to make operational preparations to outflank the Austro-Hungarian fleet; secondly, to order all the anti-aircraft weapons of the whole fleet to be brought into combat condition, and thirdly, to order aircraft carrier carrier-based aircraft to take off in two batches to bomb the Austro-Hungarian fleet, so be it ".

"Yes, General!" The combat staff officer wrote it down with a pen, stood up and saluted, and then turned to leave.

On the cruiser Pomfret, the communicator in the sonar detection room took the phone and reported to the command module: "Report to the captain, our ship has reached the top of the enemy submarine!" ”

After hearing this, Captain Meng Tingrui took the phone and immediately said: "Drop depth charges immediately, speed!" ”

After the order was given, five seconds later a depth charge was dropped into the sea, and after waiting for two minutes, under the influence of the pressure of the sea water, the depth charge exploded, and a large amount of sea water came out from under the surface of the sea.

The observer standing on the side of the battleship observed for a while and shook his head at the officer standing at the door of the command cabin, but without success, was evaded by the enemy submarine.

Although the depth charge just now did not directly destroy the U-15, the shock caused by the explosion almost overturned the submarine, and everyone in the submarine was dizzy.

Captain Trapp knight scolded: "Damn, this cruiser is like a dog, why is its nose so sensitive, why does it always find our position accurately?" Damn, why is this happening?! ”

"Captain, I heard that the British have recently equipped their ships with a device that can detect underwater submarines, is it also equipped with this kind of equipment on Chinese ships?"

After hearing this prompt, Trapp suddenly realized, and he immediately shouted: "Quick, turn off the engine, turn off the engine!" ”

The submarine's engine was turned off, and it was suspended in the sea, but Trapp didn't know that there was also a device called active sonar on the Chinese ship, which mainly turned on this thing, and even if the underwater submarine turned off the engine, the other party could accurately find its location.

Ten minutes later, the cruiser Pomfret again found the position of the submarine and sailed over it to drop a depth charge.

A violent explosion was followed by a large number of bubbles rising from under the surface, followed by a number of floating debris rising up the bubbles, and Trapp and his crew were all buried at the bottom of the sea.

"It worked!" All the officers and men of the Chinese Navy on the cruiser burst into cheers. (To be continued......)
