I have been waiting for a long time before my retreat review. I’ve been sorry!

*******

For the need for confidentiality, the ships participating in the "Frederick Caesar" ship set sail from several ports in Ireland, France and Spain, and assembled in the Bay of Biscay. If there was no accident during the voyage, they would remain radio silent. The first half of the trip was quite smooth. When they received the order from Bernke, they had sailed 460 nautical miles from San Miguel, rather than the 500-550 nautical miles expected by the staff officers of the Allied Fleet.

With a voyage of more than 400 nautical miles, the speed of ocean freighters and large tankers will have to run for another two days, while the speed of warships can be one day and a half, and a fast one for more than ten hours. Since the US and British warships have been dispatched, the current location of "Frederick Caesar" is not only safe, but it can even be said to be very dangerous. Even if he is concerned, the German Rear Admiral Von Heinke, who is the commander-in-chief of the fleet, quickly made the decision to turn the fleet. However, in order to keep this large fleet in the steering process to avoid collisions or ships falling behind due to inadequate information transmission, he asked all ships to hang green beacons after receiving the flagship light signal.

As a result, this cautious move caused big trouble.

During the fleet's turn, a watchman on the naval transport ship "Maxi Tellow" near the right side reported to the officer on duty that he saw a torpedo passing by about ten meters away from the side of the ship. However, the officer on duty found no abnormalities when he looked at the sea surface. Besides this watchman, no one on the ship saw torpedo or torpedo tracks, and no ship in the entire fleet was hit by torpedo. The officer on duty believed that the sailor had hallucinations due to mental tension.

Coincidentally, about 2,000 meters away from the Maxi Tellow, a crew member on duty on the German tanker "Fert" saw the white torpedo tracks on the dark sea. He hurriedly called his companions, but when the other crew members came to him, there was nothing abnormal on the sea surface, and the crew members felt that their companions must have seen it.

In fact, the torpedoes seen by these two people are not illusions, but attack attempts made by the same US submarine. The submarine is called "Blue Cod", a bass-class submarine designed and built by the US Navy in the late 1920s. Its combat radius reaches an astonishing 5,000 nautical miles, which means that it can travel back and forth between Europe and the Americas under floating conditions. The Americans are worthy of a group of guys who "must be big" and have stopped building submarines with a displacement of less than 1,000 tons since the mid-1910s. The surface displacement of bass-class submarines has reached 1,400 tons, and at this time, the destroyers of many countries are only 100 tons.

The intersection of the "Cod" and the "Frederick-Caesar" fleet is both accidental and inevitable. It has been lurking in this waters in the eastern and middle Atlantic Ocean for more than two weeks. During this period, it was shy about being discovered and beaten up by the Allied destroyers, and even attacked once by the Allied long-range patrol aircraft. Fortunately, it was only a little skin trauma.

One evening before, the seaplane carried by the Frederick Caesar fleet came to explore the way. The Blue Cod, who was repeatedly attacked, saw the plane's traces from afar and dived into the water, thus avoiding the opponent's early warning and reconnaissance. The captain of the boat Major Anderson was a smart man. He knew that the appearance of the light seaplane meant that the enemy ship was not far away and was likely to pass through this sea area. So after nightfall, he did not let the submarine float as usual.

Because that is likely to be discovered by the radar equipment of enemy ships. The "Blue Cod" became a cunning and patient flounder, hiding the huge hull that is easily detected by radar under the sea surface that cannot be penetrated by pulsed radio waves. It only exposes the can-shaped command tower and the backup ventilation port to the water, quietly waiting for the arrival of prey. A few hours later, the prey arrived as scheduled and lit up the green beacon, which pointed out the attack location for the hunters.

Faced with such a good opportunity, the smart Major Anderson made a mistake that cowboys easily made, which was recklessness and indifference. He trusted the weapon commander too much, and was worried that the enemy ships would find themselves closer, so he ordered an attack early and fired four torpedoes in one breath.

The US-made torpedo with medium speed is not heard after launching, if you do not hear an explosion after seven or eight minutes, you can judge that it has not hit any target. After a cup of coffee, the sea surface is still as quiet as usual. The crew of the "Blue Cod" can't help but regret the loss of the torpedo, and at the same time, it is fortunate that the enemy did not discover itself.

The larger the size of the marine creatures in nature, the slower the movements. The perch-class submarine is not flexible, whether it is up and down or down, or steering. Therefore, Major Anderson did not let it turn around and use the tail torpedo, but waited for the crew to complete the loading and then launch a second attack. During the waiting process, the Major closely followed the movement of the enemy ships. After observing for a long time, he suddenly realized that the enemy's fleet was not simply adjusting the route, but turning around and returning!

Can the prey that comes to the door slip away? Major Anderson was very depressed. The fleet in front of him seemed to have twenty or thirty ships. With the battle situation of the Azores, this cliff was transporting personnel and supplies to the front. If you kill one, you may sink to the bottom of the sea, thousands of tons of weapons and ammunition or hundreds of thousands of land soldiers. It can reduce certain resistance for the US and British troops to attack three islands such as San Miguel in the future. However, no matter how big the submarine is, it is also a submarine. If it floats rashly, the tenth* will be discovered by the enemy's ship-based radar, and then a medium- and close-range artillery battle with short strikes. The "green cod" that is free in the sea will inevitably become the enemy's in-track delicious...

Major Anderson was worried about what to do next, but he didn't know that the submarine command tower that poked out of the water was his monkey tail, and the enemy command ship "Ruger" had already captured this clue.

The "Ruger" is a standard military-class heavy cruiser designed and built by Ireland and actively promoted to the alliance countries. Its standard displacement is 15,000 tons. It uses the 55-diameter 203mm naval gun made by Krupp as the main weapon. Its performance is balanced and comprehensive. The exported models have a high cost-effectiveness. The two ships purchased by the Irish Navy have been enhanced in terms of air defense configuration and technical equipment, and are basically undergoing experimental improvements every year.

.A very important reason why the German Navy Staff selected the "Ruger" as the command ship of the "Frederick Caesar" escort fleet was that it was attracted by the mc-iib short-wave pulse radar it equipped with. With this expensive technical equipment, the escort ship can effectively monitor and alert the 50 kilometers of waters around the fleet when the reconnaissance aircraft cannot take off, which is particularly valuable at night and in bad weather.

A well-trained fleet can turn around in the way members turn their heads while marching. If a temporary fleet wants to maintain its formation, it can only turn around in the most primitive and clumsy way, that is, to turn around in a circle. In the first half of the circle, the "Ruge" as the command ship continued to sail westward, and its relative position with the "Blue Cod" gradually approached. Although the radar reflection waves of the submarine command tower were very weak, the superb Irish radar soldiers still noticed the only abnormality in the surrounding waters and reported to the bridge as soon as possible.

The current situation is special. Major General Von Heinke, the first commander of the ship, and Colonel Farrell, were both on the bridge at this moment. They received a report from the radar room. The two briefly exchanged opinions and decided to defy rather than to rebel and immediately dispatch the destroyer closest to the suspicious target to explore.

After receiving the order, the German destroyer "Willie Fraser" quickly deflected its course and slowly sailed to the designated area to facilitate sonar detection. The crisp battle alarm ringtone kept ringing in the destroyer's cabin, and all the crew members rushed to the battle position. The artillery on the ship began to rotate. Under the order of the officers, the anti-submarine personnel began to remove the insurance of the deep-water bomb and put them into a state of waiting to be fired.

The "Willie Frazel" gradually approached, and the Americans quickly noticed the approaching danger. Major Anderson quickly ordered the submarine to dive completely into the water and then remain static at a depth of twenty meters. Past experience told him that a submarine that was still in the water was difficult to detect by enemy ships, not to mention that the sea was pitch black and without moonlight and starlight. Even if the enemy ship was close to a hundred meters, it might not be able to dig out this cunning halibut.

In this way, the "Green Cod" was quietly suspended in the water, and the periscope in a closed state was less than five meters away from the sea. If an enemy destroyer passed directly above it, the two might even have a direct collision.

On the other hand, although the radar of the Ruger lost its target, it can guide the ship to eliminate potential threats through technical positioning methods combined with modern and traditional. In its radar room and navigation room, many technical officers worked closely together to use radar data, navigation drawings and mechanical calculators to calculate a series of coordinate parameters and inform the communication department that the communications troop converts these parameters into light signals, so that the "Willie-Fraser" can be targeted.

On the bridge, Major General von Heinke said to his temporary partner: "If that was really an enemy submarine, we must sink it here, otherwise it will soon report our exact location to the enemy fleet, after all... radio interference technology is not as reliable as people think."

Colonel Farrell responded lightly: "At this point, I feel that the probability of encountering an enemy submarine is more than 70%. Considering that the depth of the seabed here is almost infinite, the probability of the enemy submarine successfully escape after being discovered is more than 70%. In short, our situation seems to be not very good, and this has nothing to do with whether there are enemy submarines here."

This made Major General Von Heinke feel a little unhappy, and he asked back: "I am very curious, is the Irish Navy's attitude towards this war as unhappy as you?"
