The U-039 submarine gradually surfaced after the British fleet passed overhead.

   "Quickly, immediately send a telegram to other submarines to report the news of the British fleet. This time, we will kill all of these British fleets." Doenitz ordered.

   "Yes, sir." The communications soldier immediately went to send a telegram.

   Immediately, the U-309 submarine began to chase the British fleet going south with all its strength. Because the speed of merchant ships is generally slower, far lower than the speed of submarines on the sea, the U-039 submarine can completely keep up with the British fleet. In addition, they continuously communicated the position of the British fleet to other submarines through telegrams, allowing them to adjust their course and intercept them.

  A large net composed of the submarine force of the German Navy is enveloping the British fleet. The British, on the other hand, don't even know about it.

   Submarine hunting often requires patience. For a suitable attack position, they sometimes even need to spend a whole day waiting. This time, organizing other submarines to form a pack of wolves to attack the British fleet requires close cooperation between the submarines. Otherwise, if something goes wrong, it is possible to make their plan fail.

   It was not until the afternoon that the submarine force of the German Navy completed its deployment, and a total of nine submarines participated in this operation. Except for the U-039 submarine which followed the British fleet, the remaining eight submarines formed an encirclement from the front, left and right of the British fleet.

   At 3:45 p.m., submarine U-048 aimed at a British merchant ship and fired a torpedo.

  533 mm heavy torpedo, less than 500 meters away from the merchant ship, quickly rushed towards the merchant ship. The people on the merchant ship didn't notice it at all, as if they didn't realize that the crisis had come to them.

   "Boom!"

  A huge explosion sounded on the side of the merchant ship. The flames shot up into the sky, and the huge merchant ship shook violently. The entire side of the ship seemed to have been bitten off by a monster.

  The defense of the merchant ship was already very bad. Under the explosion of the high explosives of the torpedo, the merchant ship was directly torn apart.

  The seawater poured into the merchant ship frantically, and the sinking of the merchant ship was irreversible.

   "What's going on?" When the merchant ship was attacked, both Major Edward and Captain Martin were startled, and they looked at the merchant ship in front of the formation with binoculars.

   "Is it an enemy attack? Or was there an accident?" Captain Martin asked.

   Major Edward's face has become ugly: "Get ready to fight, I think, we are in trouble. Damn the German submarine, we are being targeted by them."

  At this time, several more merchant ships were hit. This is an attack from a submarine ambushing in the surrounding area.

  For the submarine force of the German Navy, such a large British fleet is like a feast for them to enjoy. Everyone hopes to add some to their sinking numbers.

   "God! It's not just a submarine. How many submarines did the **** Germans hit in this sea area?" Major Edward couldn't help but exclaimed.

  If they only encounter a German submarine, they can also use destroyers to siege, sink it, and drive it away no matter how bad it is. But now there is not just one submarine, but several submarines. Therefore, this time the problem may be troublesome.

   "Order the destroyer to launch an attack, find out those German submarines, and sink them! They must never be allowed to attack our merchant ships again." Major Edward ordered.

  The destroyer that provided the **** for the fleet, like a ferocious hound, rushed to the place where the merchant ships were hit.

   It's just that the German submarine has launched a torpedo and hid in the water again, waiting for the next opportunity to attack.

  The entire fleet is already in chaos. After being attacked by German submarines, these British merchant ships fled in all directions like frightened sheep. In the panic, some merchant ships even collided with each other. After the hull was smashed, they sank directly into the sea. The whole scene became extremely chaotic.

   "Boom! Boom! Boom!"

  The destroyers of the British Navy also continuously dropped depth charges into the sea in an attempt to blow up the German submarines hiding in the sea. However, they had little success. Submarines don't stay still underwater. Although the submerged speed of the current submarine is still very slow, it is not something that a destroyer without sonar can catch. Destroyers want to sink submarines, more can only rely on luck.

  A periscope rose from the sea, vigilantly observed the surrounding area, and after no danger was found, it rose to the height of the torpedo launch.

   "The merchant ship ahead is 600 meters away from us. The No. 1 launch tube is ready, launch!" Doenitz ordered.

   "Boom!"

  A 533mm torpedo shot out of the torpedo tube and quickly shot towards the British merchant ship ahead.

   Soon, the torpedo lightly kissed the side of the merchant ship. Through the periscope, Dönitz clearly saw that the submarine was blown to pieces during the explosion.

   "Quick, dive, the British destroyer is here." After seeing a destroyer rushing towards them aggressively, Dönitz gave an emergency dive order.

  The water tank of the submarine began to fill with water, and it quickly dived into the sea. When they dived to more than 50 meters underwater and began to submerge at a speed of five knots, the depth charges of the British Navy also fell into the sea.

   "Boom! Boom!"

  A dull explosion sounded, and the shock wave slapped on the hull of the submarine, making a crackling sound. Even the submarine began to shake under the action of the water waves.

   After the destroyer of the British Navy launched an attack, it turned around and left after not finding the target. Denitz and the others breathed a sigh of relief.

  Submarine is a weapon with strong concealment. But at the same time, once encountered an attack, it is difficult to fight back, and can only escape the enemy's attack by dodging.

   The melee ended after more than half an hour, and the submarines of the German Navy withdrew one after another. Although not all British merchant ships on the sea were sunk, these German submarines had no torpedoes and had to evacuate. The British destroyers on the sea searched for them like mad dogs, making it impossible for them to surface and attack those merchant ships with artillery.

   They are already very satisfied with being able to kill so many merchant ships. Better than keep going and get sunk by British destroyers.
