It's 4 a.m. it's still dark. The u-211's break is over. Prion looked up at the sky and waited for his crew to get back into the submarine one by one. He was used to being the last to enter the submarine so that he could check and cover the hatch himself.

Soon everyone got into the submarine. Prion closed the hatch, and the bad air replaced the fresh and cold sea breeze.

"Keep diving! The depth is 35 meters. Five minutes later, save electricity and keep heading. " Prion ordered out loud.

His first mate was in position, and he repeated his order loudly: "continue to exhaust and dive, the depth is 35 meters underwater. Turn off the main lighting after 5 minutes! "

The situation has become clear and the combat mission has been deciphered. Prion has told his crew that the next day's mission is to enter Scarpa Bay. As the next day would have to be spent underwater, prion ordered everyone to save air and electricity and not to move around if it was not necessary.

After about five minutes, the main lighting in the submarine was cut off. The instruments in the submarine control room, the slight leakage of water droplets in the pipes and the sound of sea water squeezing the hull from all sides were mixed together, which made people feel creepy. With the mechanical rotation and roar, it became the noise in the submarine. All around was darkness, with only a few lights on the instruments, so that people in the submarine could see the outline of the surroundings.

At 4 p.m. the next day, all the crew finished their meals, the tables, chairs and utensils were sorted out, and the crew's bunks were folded up.

"You take a few people with you and put the explosives you bring in at the bottom of the submarine." Prion felt that time was up, so he began to prepare for everything before the attack.

The chief officer nodded and walked out of the command cabin with several people holding flashlights. They loaded explosives in the torpedo cabin, power room and other places. Several people's expressions were very serious. They knew that the task this time might be really difficult.

Then prion gave the order that everyone check their life jackets. At the same time, these submarine officers and men carefully tore off the fleet logo on their hats to avoid exposing their identity after being captured.

"Damn it Prion knew that there would be a long wait, waiting for the miracle to come. He held his pocket watch and was in a nervous mood. So he swallowed a mouthful of saliva and forced himself to calm down.

"Attention! We're at risk of sinking every minute! Everyone, get ready to fight! We're going to Scarpa Bay. Our task is very simple - to make a scene in Scarpa Bay and avenge our old high seas fleet. " Prion announced the full order in a loud voice.

Some people in the command cabin of the submarine were strangely quiet, and all of them stared at their captain in silence. They thought it was a reconnaissance mission or a mine laying mission, but they never thought that this time they were really here.

"Revenge After a long time of shock, another sailor finally echoed in his voice: "revenge for those seniors of rainbow operation!"

"Yes! Revenge! We're going to let the Brits know! Who is the master of the sea The chief mate said excitedly.

"Yes! That's what we want! Even if you die, you have to tear off a piece of meat from the British! " Brian nodded and said, "keep heading! Keep going

As time goes by, everyone is waiting for the moment when they can act. It's like the bride waiting for the sedan chair, full of joy, looking forward to, but extremely nervous.

"Periscope height!" I don't know how long it took, prion finally said. He put his face up to the periscope, raised the only device that could observe underwater targets, and looked around carefully.

"This channel can't be submerged, or it will hit those sunken ships." After looking at the surrounding scenery, I compared the navigation map with the first mate. On the map, the location of many sunken ships was densely marked. It was an accurate map made by German merchant ships and spies for many years.

"Then what? Shall we go up? " The chief officer looked at his commander in surprise and asked in disbelief.

"Float up!" Prion nodded.

At 7 p.m., prion gritted his teeth and finally ordered the submarine to begin to float. The motor began to run at full speed and drove for another half an hour at a depth of about 25 meters until the sonar provided an underwater interceptor reported that it had not detected any noise coming from the sea. Prion again looked around with a periscope.

He felt that he had not been so cautious and nervous for several years. When he floated to a depth of 5 meters, prion ordered the periscope to be raised again. After observation, night had fallen and the sea was in good condition. At 7:15, prion finally made up his mind and ordered to surface.

The submarine's airtight water tank squeezed the sea out of the submarine, and this giant of nearly 1000 tons finally surfaced. Under the cover of night, the u-211 submarine was sailing almost close to the coastline.

Because of the air source, the diesel engine on the submarine began to run. In the next two hours, the u-211 was very dynamic, sailing at a high speed to the northwest of helm strait with the tide at almost full speed.

But at 9 p.m., they were in trouble. A British freighter appeared on their route, so the u-211 submarine began to dive in a hurry. Finally, a minute before they were found, they dived below the surface of the sea. In order to avoid passing ships on the sea, submarines often dive into the water and have to contend with the increasingly strong current. There is some deviation in the calculation of the time of entering Scarpa Bay. A strong tide is flowing into Scarpa bay at this time. Like a canoe in a torrent, the u-211 narrowly entered the cork Strait at night. At 23:31, the submarine began to enter Scarpa Bay, during which the bottom of the hull even collided with the mooring line laid on the seabed, causing the submarine to turn sharply to the right and grounding. Due to the fact that prion had previously ordered the submarine to move in a semi submerged state according to the water depth, now it had to continue to exhaust into the water tank, so the u-211 successfully floated again. The channel ahead widens and the current slows down. In order to prevent submarine attack, there are many man-made sunken ships and other underwater obstacles in the channel less than one kilometer wide. According to the information collected before departure, it is extremely difficult to enter Scarpa Bay by the route through the Strait of cork, which is almost difficult to penetrate. At this time, the u-211 submarine was sailing along this route. At 12:27 midnight, prion finally confirmed a result. They have entered Scarpa Bay. But when everyone was relieved, the most devastating thing happened. All of a sudden, a bright light hit u-211, shining its command tower shell. Prion, who was watching everything from the command tower, was stunned by the scene. He was even ready to go all out. The light came from the headlights of a taxi that happened to pass by on a road in the small town of San Marin on the shore. Under the strong light, Prynne and the chief officer on the command tower can even see the trucks and sentries used by the Royal Navy officers and soldiers on the shore. Everyone panicked. It seemed that their whereabouts had been exposed and it was inevitable that they would be attacked. The chief officer's hand has been pressed on the holster at his waist, while prion has even pulled out his P-38 pistol. However, as we all know, not to mention relying on these short guns in their hands, they have no chance of winning even if they count the 88mm gun in the bow and the 40mm anti-aircraft gun in the stern. Prion, holding his breath, could even see two British soldiers lighting cigarettes at each other's sentries. Maybe the two men would fire a warning gun in the next second to let prion give up their last hope. This time, it seems that God chose to take the German side, and prion's worry never came. Fortunately, the taxi didn't find the submarine. Instead, it turned a corner and drove on towards Scarpa Bay“ If I do it again, I'll be scared to death here. " The chief officer leaned against the shell of the submarine command tower and gasped, his hands still shaking. For a few seconds, he even admired prion, who was silent, and felt that the commander was extremely calm. But this worship didn't last long, because when the chief officer bowed his head, he saw his captain inserting his P-38 pistol into the holster with trembling hands. He failed twice in a row, but he failed to put it back“ Watch out! We need to find the best attack position. There's only one chance. Now that we're here, we'll make a big fight Prynne recovered for a while before he said that. The chief officer nodded, and the two men put up their telescopes and began to continue to guard against the surrounding situation. In any case, there is no way out. The current task of u-211 submarine is to find the attack target as soon as possible. Prion, while directing the submarine to continue its westward voyage, carefully observed the sea. A dark night hung over the British Isles, and the entire Royal Navy was dejected by the defeat off the Dutch coast. Under the leadership of Churchill, the Navy minister, the king has ordered more warships to be called in to deal with the threat of the German Navy. So in Scarpa Bay, almost all the naval aircraft carrier power that the British navy can hold is gathered. Churchill plans to use the same number of aircraft carriers to cover the attack of battleships on Wilhelm harbor and kill the German high seas fleet.
