It was almost 30 years after the end of the second world war before the wartime codebreakers of Bletchley Park were allowed to break their cover and recount what is now recognised as the greatest single British contribution to the Allied victory. It was the obsessive and instinctive guardedness of this kind that allowed the almost miraculous preservation of Bletchley's secret source of information throughout the war. They were helped by the unshakeable German conviction that the Enigma codes - several variants were used by each of the three armed services - were impossible to break. Ultra's contribution did not begin until the spring of 1941, as the Enigma cipher was progressively decoded. The effect was powerful, if not always decisive, in the fluctuating north African campaign. By the time of the battle of Alamein, Ultra's influence was less powerful than the decisive superiority - 5 to 1 - in tanks and airpower enjoyed by the Allies. The disappointment felt at Bletchley was that, given the constant stream of intelligence being supplied to Montgomery at the time, he was not able cut off Rommel's retreat before he reached Tunisia. Its influence in the war against the U-boats - where the naval Enigma was broken from the second half of 1941 - helped provide the information about U-boat locations to re-route convoys to safety. It has been calculated that about 1.5m tons of shipping were saved and valuable time was bought to build new ships and develop more effective anti-submarine defences. Четвёртый английский телеканал (Channel 4 Television Corporation MCMXCIX) показал в 1996 году 4-серийный телесериал по одноименной книге Михаила Смита "Station X. The Codebreakers of Bletchley Park (Станция Икс. Дешифровальщики Блетчли Парка)". Это история взлома кода "Энигмы" в Блетчли-парке во время Второй мировой войны. Этот замечательный подвиг - взлом кода, который немцы считали нераскрываемым, - должен был сыграть одну из главных ролей в победе над фашистами: 4-я серия - Война машин (без перевода). ---------- 3-3. Bletchley Park Tour [docu in full] http://youtube.com/embed/OuEHcJ7CCzg 게시일: 2012. 9. 7. Captain Jerry Roberts, UCL German alumnus and WW2 codebreaker, on 11 March 2009 he delivered his talk - 'My Top-Secret Codebreaking During World War II" at UCL about his experiences breaking the 'Tunny (the Lorenz)' at Bletchley Park.() He was a senior codebreaker and linguist in the Testery, who cracked Hitler's Most Secret Tunny code: a much more complex 12 wheel cipher system than the well-known 3 wheel Enigma. ----- () 게시자 주: 바로 이 talk 의 녹화가 아래의 제3-4항에 있다. ----- Tunny was declassified only in 2002. Most people in 'the Testery' have died by now, the work of the Testery remains seriously undervalued and poorly recognised by the public, Testery's achievements had very little or nothing. Captain Roberts is the last British survivor of the Tunny codebreakers. For the last 4 years, he has been campaigning for proper recognition for Bletchley Park's "Heroes", especially for his colleague Bill Tutte who broke the Tunny-system to help shorten the War by at least 2 years. If Bill Tutte had not broken the Tunny system, if the breaking of Tunny messages had not been so vital, there would have been no need for a Colossus at that time. Tunny declassified only a few years ago, for the first in 2011, BBC Timewatch made a programme 'Code-breakers -- Bletchley Park's Lost Heroes' http://www.youtube.com/watch?v=JF48sl... This documentary won two Academy Awards BAFTAs of the 2012, for the best documentary and best editing! Great story, watch it if you can, very moving! ----------- 3-4. Capt.

Bletchley Park is an estate located in the town of Bletchley, in Buckinghamshire, England, which currently houses the National Codes Centre and the National Museum of Computing. During World War II, Bletchley Park was the site of the United Kingdom's main decryption establishment, the Government Code and Cypher School (GC&CS), where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines.
