Iron Cross

On the eve of the outbreak of World War II, the Polish Cryptozoological Bureau disclosed to the British intelligence agency the cracking technology of the German Enigma cipher machine. Later, with the seizure of code books and physical cipher machines during submarine warfare and the development of relevant computing systems, the British Finally, the cryptographic system was cracked. The main job of Bletchley Manor is to analyze the data from the Axis powers collected by the telegraph listening station provided by the British. At first, these initial data would be sent quickly by intelligence agents on motorcycles. Later, the listening stations would directly transmit the data by teletype machines.

The water tower in the manor was once converted into a radio room and named "Radio X". However, because the long antennas protruding from the radio room could easily expose the target, it was soon moved away from the manor to prevent the entire base from arousing suspicion from outsiders. This is also why Skorzeny was able to find aerial photos in old archives. Initially, the Luftwaffe discovered these wires during reconnaissance and used it as a backup communications center for London. Later, it was discovered that the obvious antenna group was missing. Bombing was abandoned.

Now, this aristocratic manor hidden in the Buckinghamshire countryside has become the center of Britain's wartime secret keys and cipher indexes. In country houses, a large group of special mathematical experts are deciphering German secrets, and the SkyThunder Commando team The mission is to find and destroy them.

The sound of oars and water broke through the unique silence of the night. After a day's hard work, Randolph and Schubert successfully controlled a fishing boat. Now the commandos who came with the submarine were carrying them. The weapons and the eight pieces of equipment were transferred from the kayak to the fishing boat.

This was the most thrilling moment during the landing. Luck seemed to be favoring Rank and his party. Just after they boarded the ship, the unique rainy night weather of the British Isles came again, and the entire port and dock area were shrouded in rain and fog. No one can be seen from 30 meters away.

"You are finally here." Randolph deliberately lowered his voice. "There are three vehicles parked at the port, an American Jeep, and the other two are military trucks, all of which are vehicles used by the port guard. Schubert and I We watched them all day before we found a way to steal it, but the hidden danger is not small. As long as they find that the vehicle is missing after dawn tomorrow, they will definitely report it to the police, which will increase our risk of exposure. "

"It's impossible to go to Bletchley Manor without a vehicle, and we can't seize it in an honest way." Rank pointed to the military police uniform on his body, "The port guard force is affiliated with the navy, they will not use the army military police. , If we come to the door, we will probably get a slap in the face, and if they ask someone to verify, it will be even more embarrassing. "

"That's right, we have to find other ways."

"But the loophole is also here. According to the British normal handling method, after they find that the vehicle is stolen, they will report it to the police and then trace it layer by layer. If possible, they will also report to the navy. If I am not wrong, this kind of cross-border The communication system between the military services will not be very efficient - as long as they follow the procedures step by step, they will never be able to react before leaving get off work today. "

Skorzeny thought about it for a long time, and finally made a decision: "It depends on your judgment. Let's take these cars and go directly to the destination."

The convoy was driving on the road and soon encountered the first checkpoint.

"Stop!" A sergeant stopped the convoy and said, "Sir? Which part are you from? Where are you going?"

"Sergeant, this is my ID." Rank handed an ID through the car window with a white-gloved hand. "We are from the Cambridgeshire Military Police. I am Lieutenant Colonel Robin. I have been ordered to escort a group of people. Send German spies and equipment to Buckinghamshire..."

"German spy?" The soldier on the opposite side looked puzzled.

"Look." Rank got out of the car and pointed at Randolph and Schubert who were tied up in the two cars. He also showed off the broken parachute, the captured radio station and other items with a German flavor. . Randolph and Schubert were swearing as hard as they could, and a string of German curses blurted out, making everyone who heard them frown.

"Sir, you are very lucky to have caught a German spy." After verification of documents, troop escort and the "genuine" German spy, the sergeant obviously believed the whole situation, "But this guy is too dishonest. You have to Gag him up."

Rank patted the other party on the shoulder and praised: "Sergeant, you have a good idea. It seems that you are usually a smart person. Come on, please shut up the spies." The team member next to him immediately found two rags that he didn't know were rags. Something else was stuffed in. Randolph and Schubert tried to struggle, but they couldn't speak.

When the convoy left the checkpoint with great swagger, Rank found that the sergeant was still waving at him.

After get off work, two teams of vehicles suddenly arrived from the gendarmerie in Bletchley Town. It was some of the team members led by Rank. Others had been sent out by him to survey the location of the installation device.

"I am from the MI5 Special Operations Group, and I have been ordered to investigate counter-intelligence matters." Ranke's first words after getting out of the car startled Captain Robert, the leader of the local military police team, who stammered Said, "Sir, I did not receive the relevant instructions."

"Of course you won't have any orders, because the target of arrest is you." Rank immediately instructed the team members to throw him to the ground. The surrounding British military police were all stunned. Rank calmly took out the MI5 document with a bright red seal from his briefcase, "This is an official document. According to the investigation, 'Robert is a German spy who has infiltrated the team. For the sake of caution, Lieutenant Colonel Robin is fully responsible for verification and identification.' Everyone, you are all within the scope of identification. I hope you will explain the situation to me one by one, including how to handle cases in normal times, how to deal with emergencies, and how to coordinate relationships around you. We can't wrongly accuse a good person, let alone let a bad person go."

These military police were first shocked by Rank's preemptive momentum, and then they were frightened by this piece of paper. None of them resisted but chose to cooperate. No one thought of calling to verify the situation. They were all controlled by the commandos. Half an hour later, Skorzeny came out to report: "All solved."

"Very good, I'll stay here and act according to circumstances, you guys go your separate ways."

At nightfall, all the devices had been deployed and started working, just surrounding the entire manor in eight directions. The method of playing the role of military police was very successful. No one recognized that the military police had completely changed their roles today, and the order of the town was as calm as ever.

At nearly 12 o'clock in the evening, a team of experts led by Professor Alan Mathison Turing of Cambridge University was busy working in the manor. They received a clear order from MI6 to come, and everyone had to put down other work at hand and devote themselves to code deciphering. Two days ago, the German side suddenly launched a new code system, and the German code table held by the super secret instantly became a piece of waste paper.

What's more terrible is that the monitoring department told these experts that in North Africa, in the Low Countries, in Germany, and even in the Atlantic, the strength of telegraph signals suddenly increased unprecedentedly, and the communication volume increased several times. It is said that even Prime Minister Churchill was alarmed by this news. The intelligence department unanimously judged that the Germans would take a big action: such a sudden unified change of the code system could not be completed overnight, which means that the German side had been preparing to start this matter a few weeks or even a month ago.

"Conspiracy, there must be a huge conspiracy." Prime Minister Churchill gave a death order to crack the Germans' new code as soon as possible, so all the code and intelligence experts in the country gathered in the manor overnight, and 12 o'clock was the moment when their collective wisdom reached a climax.

"Professor, I think the Germans may have enabled a new compilation thinking, rather than simply adding rotors to the Engelhard code machine. Because the current code logic system is completely different from the original one. We must adjust our thinking."

Turing nodded approvingly: "MacDonald, you are my best student, what do you think?"

"My idea is..." He explained it quickly, and Turing exchanged opinions with several other professors and thought it was initially feasible.

"You go and try it first, find two researchers to help..."

At this moment, a dull sound of an airplane flew over the sky, and someone laughed and said, "Is the Royal Air Force going to attack the Germans again today?"

"No." Someone said in confusion, "It shouldn't fly so low in this place..."

Turing said, "Gentlemen, don't worry about the Air Force, we must crack the code as soon as possible. I heard that the Prime Minister is so anxious that he is afraid of any mistakes on the North African front or elsewhere, and he has sent five consecutive telegrams to General Montgomery." How could they know that this date was deliberately chosen by Hoffman, with the purpose of suddenly changing the code on the eve of the action, so that British cipher experts would gather together to think about how to crack it, and then create an opportunity for the commandos to catch them all in one fell swoop.

"The Germans' move is really unexpected..."

Before he finished speaking, he suddenly heard the sound of heavy objects falling to the ground, followed by explosions and screams: "Air raid, air raid, the enemy is attacking..."

At this moment, there were three Lancaster bombers in the air, constantly dropping bombs according to the instructions of the ground positioning system. These four-engine bombers were collected by Germany from the wreckage of British planes shot down. Those planes that were lucky enough not to fall into pieces could still be used after being repaired. In the evening, they disguised themselves as a Royal Air Force bomber formation heading to Germany for bombing and then turned back halfway, and used the British transponder code to deceive the ground radar station. Then they began precision bombing according to the guidance of the positioning system. This time, they dropped no ordinary bombs, but the few German solidification bombs that were generally reluctant to use. Bletchley Manor was too big and there were many people. It was difficult to completely destroy it with high-explosive bombs alone. At the same time, there were a large number of cabins inside, and the effect would be twice the result with half the effort after using solidification bombs.

The commandos who had been paying attention to the movement on the periphery saw it clearly. The fire suddenly broke out, and all the buildings were burning. There were running figures and screams everywhere in the fire.

Skorzeny gave orders with confidence: "The Air Force has done a good job. It's our turn next. Everyone be careful and don't get involved with that thing, otherwise you don't know how you will die."
