18th September 1938
As Hitler demands territory in Czechoslovakia, war seems inevitable. GC&CS sends most of its staff from London to Bletchley Park and prepares for the oncoming conflict. For three weeks, around 70 staff work from the mansion. When locals ask questions, staff say they are here for the pheasant shooting season. Work starts immediately but the conditions are crammed and chaotic, with mounds of books and papers scattered around. There are too many people crammed in for the codebreakers to concentrate. Even so, there are not enough of them to do everything.
War is avoided when Hitler is allowed to seize Czechoslovakian territory. It would not be, as Neville Chamberlain claims, “ peace for our time” but it is a breathing space. CG&CS uses it to learn the lessons of this first move.
The codebreakers return to London, When they come back to Bletchley Park, they willl be better prepared.

This is one of the largest rooms in the Mansion. Temporarily adopted as an office by the Military Section in 1939, the Dining Room was mostly used during the war as a place for eating and recreation.
In the late 1930s, there were a few hundred staff at Bletchley Park, and meals were served to them by waitresses. In 1938, a top London chef from the Savoy was even temporarily brought in by management to cook for those early codebreakers.
In 1942, the operation at Bletchley Park had grown much bigger and different catering arrangements were established. The large new canteen opened on Wilton Avenue, and this space, whilst still used as a dining room, was sometimes handed over to the Recreation Club for lectures.
The Leon family, who owned Bletchley Park pre-war, were responsible for the design and construction of this splendid room. Much of it’s Edwardian grandeur remains, despite the thousands of people who have worked - and eaten - in here since
The Watch
Work at BP went on around the clock. In this room there were four Watchkeepers on each shift, led by Watch No.!. Most were civilian experts in German, able to fill any gaps in the deciphered messages before translating them. As they had no military experience, special Military Advisers helped compile the final reports.
Polish Bomba
(scale replica)
The Bomba machine was developed by the Poles to help find individual Enigma keys. The rotors you can see on top mimic the rotors of an Enigma machine.
The machine cycled through possible Enigma rotor positions. It looked for patterns that allowed the starting rotor settings for a particular message to be identified.
Chauffeur’s Hut
This hut was a replacement for a much earlier one built at the rear of the Mansion very soon after the 1938 occupation of Bletchley Park by the Government Coade and Cypher School.
Ordered in August 1943 and built by October, it was necessary as the number of drivers grew along with the BP workforce throughout the war, so that at the end of March 1945, 133 drivers were covering 32,000 miles weekly. they provided transport for staff to and from their billets as well as chauffeur services for senior BP management.

Alpha is a bloc symmetric encryption algorithm I created during my spare time. I used Java with JavaFX.
My software is not intended to be distributed. Even if I wanted, I can't due to laws :)
* The size of the encryption key is variable. It only depends on you when you create the key ;
* A file is cyphered by blocs which size is the key size ;
* Every variation of the key has repercussions on the whole generated cyphered file.
The key is unique ;
* All types of file can be cyphered : txt, images, rar, zip, exe, videos, ... everything you want without risk using a minimal memory ;

The Ballroom
During early WW2 the Ballroom was used as a teleprinter room, like the Billiard Room next door.
By 1942, the teleprinters had been relocated to the huts and specially constructed buildings. It was suggested that the Ballroom be partitioned to become a Typex machine room repair workshop.
However, it was decided to use the Ballroom for more appropriate activities, and in 1942 the Recreation Club moved in. The Reels (Scottish Dancing) Section was based here in 1943. The space was later converted into a quiet reading and rest room where staff could relax.
The Ballroon is the largest room in the Mansion. The walls are covered in ‘linen-fold’ oak panelling and the ceiling is oak beam and plaster. The room was added as an extension to the existing house by its last resident, Sir Herbert Leon, in the 1880s.
Decoding Room
Once the day’s Enigmas settings, or keys, had been broken in the Machine Room, intercepted messages were typed into Typex machines adjusted to these settings. The deciphered messages, usually in German, then emerged from the machine. The noise from the Typex machines when the ciphers were being decoded could be heard throughout the hut.

Enigma I plugboard with six cables
(replica)
In the buildup to WW2, German forces used a plugboard with Enigma. The plugboard cables connected pairs of letters to each other, switching one for another.
During encryption the electrical circuit passed twice through the Enigma rotors, entering and exiting via the plugboard.

This block housed the Sections that handled Enigma ciphers used by the Italians, French and other European nations. Codebreakers trying to crack the unsolved Japanese codes also had their officers here. Much of the block was later occupied by staff working on naval Enigma ciphers which the Germans had made increasingly complex.
1947 Sunbeam Talbot
2 litre Sports Saloon converted to a Tourer
Shipped to Simpsons of Madras when new on 12th September 1947, this car was oringally light green, which is still visible in some places. Following its return to the UK the car was generously donated to Bletchley Park Trust by Mick Jagger after starring in the film Enigma (2001) which was produced by Jagger’s film company.
Loosely based on real events, the film follows the story of cryptanalysts at Bletchley Park facing their worst nightmare: Nazi U-boats have unexpectedly changed their Enigma cipher and a merchant shipping convoy with 10,000 people on board is in peril.
Jagger required a period sports car for the starring role, which had a large enough boot into which a secret compartment could be built to house the Enigma machine. A Sunbeam Talbot 2 Litre Tourer would have been ideal, but they were rare in 2001, therefore this Saloon was acquired. The while of the body from the scuttle backwards had been removed and replaced by a custom 4 seater Tourer body and windscreen with the required compartment behind the rear seats. Notice the blackout headlights.

During WW2 this room was filled with teleprinters and the staff who operated them. Teleprinters were noisy devices used for transmitting and receiving messages in text over the ordinary telephone network.
Access was through the bay window entrance. it connected to a newly built annex containing a telephone exchange (now demolished). It also provided access to the Ballroom beyond, where more teleprinter machines were housed.
The Billiard Room was part of the early mansion built by Samuel Seckham between 1881 and 1883, It was originally a freestanding single storey building connected to the rest of the house by a doorway in the east wall (the wall containing the current entrance). The walls are particularly thick in places, as you would expect of exterior walls.
After the house was bought by Sir Herbert Leon in 1883, the room was made taller and the high ceiling, resembling a medieval great hall. was installed. The large recess at the far end contained a fireplace.
