On August 15, 1939, the British Government School of Cipher was the first to move into Bletchley Garden, in which the Admiralty, Military and Air Departments of the school were all deployed on the first floor of Bletchley Manor, and the top floor was used by MI6. In addition, the Bletchley Manor also has a telecommunications department, a teletype room, a kitchen and a dining room for the code-breaking staff.

FROM 1943, BLETCHLEY GARDEN IMMEDIATELY USED THE WORLD'S FIRST DIGITAL ELECTRONIC COMPUTER TO DECIPHER A GERMAN TELETYPEWRITER CIPHER SYSTEM CALLED TUNNY, WHICH WAS DESIGNED BY TOMMY FLORAS AND WAS ONE OF THE GREATEST CONTRIBUTORS TO THE SUCCESSFUL DECIPHERMENT OF GERMAN CIPHERS.

During the war, a number of wooden huts were built in Bletchley Garden for intelligence gathering. These huts are named after numbers, and they work in the following ways:

Hut 3 – For intelligence purposes, it specializes in translating and analyzing the Enigma cipher system used in the Army and Air Force

Hut 4 - Intelligence purpose, dedicated to the analysis of the Enigma cipher system used in the Navy

Hut 6 – Dedicated to the decipherment of the Enigma cipher system used in the Army and Air Force

Hut-8 – Dedicated to deciphering the Navy's Enigma cipher system

Huts 10 and 11 are respectively the meteorological department, and the "bomb", the tool for deciphering the Enigma code......

Therefore, the German army's Enigma cipher machine was quickly deciphered, so that Britain, the United States, the Soviet Union and other countries knew very clearly the military deployment of the German army, the situation of troops, and the research and development of weapons and equipment, so that they could calmly deal with the German attack.

However, since Chen Yanlong modified the Enigma cipher machine, Britain, the United States, and the Soviet Union were able to detect much less information about the military deployment and combat operations of the German army, and in many cases there was no way to decipher it.

But even so, scientists in Britain and the United States, as well as codebreakers, are trying their best to develop more advanced computers and find ways to decipher them to deal with the code-breaking work of the Enigma cipher machine after the German army's repair.

"How? Annie? Did you intercept the contents of a telegram about the movements of the German Navy in the Mediterranean? ”

Just as Rommel was resting on the aircraft carrier fleet, a female officer from Intelligence Division 6 asked anxiously about a female codebreaker who was intercepting Germany's Enigma naval code.

"It's being intercepted, give me a little more time, this time we will be able to successfully decipher the Enigma naval code of the German Navy! Ensign Liz! ”

Anne, the codebreaker, replied faintly as she concentrated on intercepting the German code.

"Yes! May God bless us! Since the Germans changed the code, it became more and more difficult for us to decipher their code! I heard that even Prime Minister Churchill has paid close attention to our decipherment work, and has issued a very strict order that we must re-decipher the German Enigma code in a short period of time! ”

Second Lieutenant Liz replied sullenly, too.

"Yes! I didn't expect that the Germans would be able to modify the original Enigma cipher machine, I originally thought that Mr. Bill Tutt, Mr. Tommy Floas, Mr. Max Newman's Nemanry department, and Mr. John Trollman, together with them, had completely deciphered all the German cipher machines, who knew that something unexpected would suddenly come out! ”

Anne, the codebreaker, was also in mixed feelings.

"Hmmm! But I still believe that Mr. Bill Tutt and Mr. Tommy Floyas will find a solution again, and the final victory will be ours, because we are working for a just cause, and this damn world war should have ended sooner! Because there are so many people who died, and they were all those damned Germans! ”

Ensign Liz was silent for a moment, but comforted herself as if she were self-motivated.

"Hmmm! Yes, we will win! ”

Anne, the coder, also nodded lightly and replied.

But it was the deciphers Anne and Lis, two high-ranking staff, who were able to talk about it in the Bletchley Manor, and know that they were in the process of deciphering the German Enigma cipher machine, because most of the people in the manor were ignorant of the deciphering work they were participating in, except for the secrets known to a few wealthy and powerful people.

In the case of people of class and class, they are only insignificant members of the vast administrative apparatus of the estate; They will not be told what the true nature of the work at Bletchley Manor is.

Most of them were working day and night on the form of the "circle and cross game", and there were also sentinels, oaths, threats, guns, high walls, and gates in the manor, so that the vast majority of the codebreakers were isolated from the world, and the second lieutenant could not casually discuss the matter of the code.

Of course, apart from intelligence expert Ralph Tayster, who leads a four-member decipherment team called the "Taysteli Group", Robert is one of the four veteran members, codenamed "Jerry". Later, the team was expanded to 9 members, with as many as 118 related staff, except for those senior personnel who worked in three shifts throughout the team.

At this time, Bill Tutt, Alan Matheson, and Tommy are also in an emergency meeting at the manor.

"The original Enigma cipher machine was a complex cipher machine composed of three rotors. Under this system, the machine can encrypt messages into a jumble of letters. But in nature, we finally found out that the German army's improved Enigma cipher machine has an extra rotor, which means that the work of deciphering this cipher machine is 26 times more complicated at once! ”

"If we want to crack this method in the short term, we still need a while, at least a few months, as long as a year, unless we have more advanced digital electronic computers, or computers, if the Germans also configure technologies such as mapping systems into their Enigma cipher machines, then it will be even more difficult for us to decipher their codes!"

During the meeting, Alan McTheson was the first to stand up and explain.

Known as the father of computer science and artificial intelligence, as well as the general counsel of the British and American code-breaking departments, his face was also quite solemn at this moment, he glanced at the audience, and then waited for the next person to answer him.

"Do you have any good solutions, Mr. Advisor?"

In this regard, Captain Raymond Robert, a core member of the British code-breaking team, looked at the other party with expectant eyes.

At this time, Bill Tutt, a legendary British coder expert, and Tommy were also staring at Turing expectantly.

And Turing also looked at the other party deeply, because Robert finally became a milestone heavyweight in the world of World War II code-breaking through years of tireless efforts, so even Aaron Turing, the computer science pioneer who led the deciphering of the German Navy's "Enigma", expressed appreciation for his work.

That's why he respects the other party's speeches and ideas.

"In addition to manufacturing more advanced electronic computers, or sending additional personnel to analyze and decipher the top code of Nazi Germany - the "tuna" code, there is no particularly good way to deal with the modified "tuna" code of the German army for the time being! ”

After being silent for a long time, Turing also said a little helplessly.

"But the nature of our navy is fighting a naval battle against the Germans in the Mediterranean, if we can't decipher the German code movements for them, then this naval battle will be a relatively difficult battle for our army!"

As soon as the words fell, intelligence expert Ralph Tester was worried.

"As you said, in addition to continuing to work hard to find a way to re-decipher the German army's "tuna" Enigma code with one more rotor, we can also send more intelligence officers to various departments of the German army to reconnoiter the military deployment and actions of the German army's top brass! ”

Turing frowned and responded.

"I'm using the methods you mentioned, but I've found out that our Prime Minister Churchill is an impatient man, and he won't give us much time!"

Intelligence expert Ralph Tester sighed softly, tired.
