h3 Video Pods of Tony Sale's talks: Tunny Room Talk and Colossus Room Talk warning! you do need a good broadband connection to see these! Colossus goes Authentic!! Recoating of relay covers grey generously supplied by RSCOATINGS of Fenny Stratford, Milton Keynes Now working on Colossus cipher pattern extraction ready for another Cipher Challenge later in the YearValves for Colossus: EF36, EF37, EF37A, 6J5, 6V6, 6K8, 807, GT1CThe Baudot teleprinter code table Codes and Ciphersin theSecond World War The history, science and engineering of cryptanalysis in World War II created by Tony Sale Between 1939 and 1945, the most advanced and creative forms of mathematical and technological knowledge were combined to master German communications. British cryptanalysts, Alan Turing at the forefront, changed the course of the Second World War and created the foundation for the modern computer. In 1991 the Bletchley Park, the wartime home of Allied code breaking, was saved from destruction by Tony Sale and some colleagues. They transformed it into a museum devoted to the recognition and reconstruction of this crucial aspect of world history, which had remained completely secret until the early 1970s. "Anoraks Corner"Break Enigma!!! and Lorenz too!!!this is for the Nerds Video pods are here!Break Lorenz!! Break real Lorenz enciphered messages using Colossus, WARNING! this may overheat your brain!! Are you up to breaking real Enigma messages? Status Log Scenario 6 now up! ENIGMA Tony Sale's reconstruction of Enigma decipherment for the film Enigma This film is based on Robert Harris's novel Enigma. Although essentially fiction, it contains detailed sequences of Enigma codebreaking which have been scrupulously reconstructed by Tony Sale. Go to these pages by Tony Sale for full details. VirtualBP An interactive exploration of Bletchley Park and World War II code breaking from 1938 to the present day. Status Log . Not perfect but ready by Friday. The Enigma Follow a sequence of pages explaining how the Enigma worked. Keyboard of an Enigma The Lorenz cipher and the Colossus A sequence of pages explains the Lorenz cipher and how it was broken by the Colossus Colossus Mk 1 rebuild slowly evolves into Colossus Mk2 by 2004 See how the dedicated Colossus Rebuild Team achieved this. The first stage of the rebuilt Colossus has been working since 6 June 1996. LEFT: (in wheelchair) Tommy Flowers, designer and engineer in 1943. CENTRE: HRH The Duke of Kent, patron, switching on.RIGHT: Tony Sale, rebuilder and curator. Bletchley Parkand its Museums: The original Mansion and many Huts in the surrounding park are largely unchanged since 1945. Open a MAP of the Park. Follow a Virtual Tour of the Park. Five pages with fifty small pictures Bletchley Park Mansion Lectures by Tony Sale Lecture Notes on the Enigma and the Bombe, on Naval Enigma and on the Colossus are available. Continue to the Lecture Index page. Original World War II Documents Fish Notes by Captain Walter Fried describing in great detail the work of the Newmanry and Testery in Bletchley Park on breaking the Fish codes, Tunny (Lorenz) and attempting to break Sturgeon (Siemans). Continue to Fish Notes. Annex to Fish Note #F 071 giving a detailed account of breaking Lorenz from Delta D and lists the Colossus runs used. Continue to Delta D and Colossus runs. Critical Observations on German Traffic Analysis in Sixta Part of the History of Sixta written by Robert G. Nunn Jr. at the end of the war. Continue to Observations on Sixta. The History of the American 6813th Detachment Written by members of the American 6813th Signal Security Detachment seconded to Bletchley Park from August 1943. Continue to Introduction to the 6813th History. The Report on the British Bombe Written by members of the United States 6812th Division who were seconded to the Bombe outstation at Eastcote in North London in 1944. Continue to Introduction to the US 6812 Bombe Report. Tentative List of Enigma and Other Machine Usages A report written in Bletchley Park in 1945. Continue to Usages Index. The German manual for the naval use of the Enigma (1940) This document, the Enigma General Procedure, was captured and translated by the British. It can now be read on this site. Continue to the Index page to the Enigma General Procedure. The German manual for the doubly enciphered Naval Enigma messages (1940) This is the protocol for the offizierte messages which were doubly enciphered for officer's eyes only. It was also captured and translated by the British. Continue to the Index page to the Offizier and Staff Procedure. The Bletchley Park Cryptographic Dictionary (1944)This document listed and defined the hundreds of specialist concepts and activities at Bletchley Park. Continue to the Introduction to the Dictionary. The Newmanry History (1945) This document, kept secret until 2000, is the most crucial part of a longer General Report on Tunny. It gives the complete story of how the Lorenz cipher was broken, from the amazing breakthrough of 30 August 1941 up to the extremely sophisticated programming of the Colossus. Continue to The Newmanry History. The Special Report on Fish (1944) This document gives a complementary account of the breaking of the Lorenz ciphers through the use of Colossus, as reported at the time by an American cryptanalyst attached to Bletchley Park. Continue to The Special Report on Fish.
