Dönitz immediately asked for a review of Enigma's security. "Enigma" refers to a family of electro-mechanical rotor cipher machines. Decryption of Enigma traffic built up gradually during 1940, with the first two prototype bombes being delivered in March and August. Earlier radar was unable to distinguish U-boat conning towers from the surface of the sea, so it could not even locate U-boats attacking convoys on the surface on moonless nights; thus the surfaced U-boats were almost invisible, while having the additional advantage of being swifter than their prey. A second explanation relates to a misadventure of Churchill's between the World Wars, when he publicly disclosed information from decrypted Soviet communications. The term "Ultra" has often been used almost synonymously with "Enigma decrypts". [a], Many observers, at the time and later, regarded Ultra as immensely valuable to the Allies. Iain Standen, Chief Executive of the Bletchley Park Trust, says of the work done there: "It was crucial to the survival of Britain, and indeed of the West." "[109], Debate continues on whether, had postwar political and military leaders been aware of Ultra's role in Allied victory in World War II, these leaders might have been less optimistic about post-World War II military involvements.[e]. [19] At the turn of 1939, the Germans made the systems ten times more complex, which required a tenfold increase in Polish decryption equipment, which they could not meet. Used properly, the German military Enigma would have been virtually unbreakable; in practice, shortcomings in operation allowed it to be broken. Boasting the world's best DJs, unparalleled production, and location in the beautiful city of Miami, Ultra Music Festival is the world's premier electronic music festival. It was broken by the US Army Signal Intelligence Service and disseminated as Magic. Next Event 7 Dec. — 2019 Ciudad Deportiva Puerta 19 Ciudad de México, México Visit Resistance Ciudad de México Site . The new higher-frequency radar could spot conning towers, and periscopes could even be detected from airplanes. The distribution of Ultra information to Allied commanders and units in the field involved considerable risk of discovery by the Germans, and great care was taken to control both the information and knowledge of how it was obtained. Each has plausibility, and all may be true. There is also a one-volume collection of reminiscences by Ultra veterans, Codebreakers (1993), edited by Hinsley and Alan Stripp. It was headed by a British Army or RAF officer, usually a major, known as "Special Liaison Officer".

In 1967, Polish military historian Władysław Kozaczuk in his book Bitwa o tajemnice ("Battle for Secrets") first revealed Enigma had been broken by Polish cryptologists before World War II. It produced a polyalphabetic substitution cipher, but unlike Enigma, was not a rotor machine, being built around electrical stepping switches.

[citation needed], The third explanation is given by Winterbotham, who recounts that two weeks after V-E Day, on 25 May 1945, Churchill requested former recipients of Ultra intelligence not to divulge the source or the information that they had received from it, in order that there be neither damage to the future operations of the Secret Service nor any cause for the Axis to blame Ultra for their defeat. [15] As stated by historian Thomas Haigh, "The British code-breaking effort of the Second World War, formerly secret, is now one of the most celebrated aspects of modern British history, an inspiring story in which a free society mobilized its intellectual resources against a terrible enemy."[16]. 50 MILE ULTRA-MARATHONS. While it is obvious why Britain and the U.S. went to considerable pains to keep Ultra a secret until the end of the war, it has been a matter of some conjecture why Ultra was kept officially secret for 29 years thereafter, until 1974. 95 RN Ultra messages from the OIC to ships at sea were necessarily transmitted over normal naval radio circuits and were protected by one-time pad encryption. Each SLU included intelligence, communications, and cryptographic elements. Their investigations were negative, and the conclusion was that their defeat "was due firstly to outstanding developments in enemy radar..."[93] The great advance was centimetric radar, developed in a joint British-American venture, which became operational in the spring of 1943. Switzerland developed its own version of Enigma, known as NEMA, and used it into the late 1970s, while the United States National Security Agency (NSA) retired the last of its rotor-based encryption systems, the KL-7 series, in the 1980s. For example, Andrew Roberts, writing in the 21st century, states, "Because he had the invaluable advantage of being able to read [Field Marshal Erwin] Rommel's Enigma communications, [General Bernard] Montgomery knew how short the Germans were of men, ammunition, food and above all fuel. [24] Several systems were used, principally the Lorenz SZ 40/42 (Tunny) and Geheimfernschreiber (Sturgeon). During that period, the important contributions to the war effort of a great many people remained unknown, and they were unable to share in the glory of what is now recognised as one of the chief reasons the Allies won the war – or, at least, as quickly as they did. At the start of the Battle of France on 10 May 1940, the Germans made a very significant change in the indicator procedures for Enigma messages. It's easy to pay bills, view statements and more. [21] Gordon Welchman wrote. The more so, since B-Dienst, his own codebreaking group, had partially broken Royal Navy traffic (including its convoy codes early in the war),[84] and supplied enough information to support the idea that the Allies were unable to read Naval Enigma. This was taken as a clear signal that Sea Lion had been cancelled. "[9] However, Hinsley and others have emphasized the difficulties of counterfactual history in attempting such conclusions, and some historians, such as Keegan, have said the shortening might have been as little as the three months it took the United States to deploy the atomic bomb.

What would have been decided about the atom bomb? Detailed reports by the Japanese ambassador to Germany were encrypted on the Purple machine. The US Army also made progress on the Japanese Army's codes in 1943, including codes used by supply ships, resulting in heavy losses to their shipping.

These investigations were spurred because the Germans had broken the British naval code and found the information useful. Information obtained through code-breaking was often attributed to the human intelligence from the Boniface network. Most Ultra intelligence was derived from reading radio messages that had been encrypted with cipher machines, complemented by material from radio communications using traffic analysis and direction finding. Another view is from a history based on the German naval archives written after the war for the British Admiralty by a former U-boat commander and son-in-law of his commander, Grand Admiral Karl Dönitz.

The Departmental Historian at GCHQ (the Government Communications Headquarters), who identifies himself only as "Tony" but seems to speak authoritatively, says that Ultra was a "major force multiplier. This was an extremely well informed, responsive ring that was able to get information "directly from German General Staff Headquarters" – often on specific request. It has saved thousands of British and American lives and, in no small way, contributed to the speed with which the enemy was routed and eventually forced to surrender. And they need venture only a reasonable distance beyond the facts to recognise the extent to which the explanation lies in the influence of Ultra. This meant that those at Bletchley Park had some time to build up experience of collecting and starting to decrypt messages on the various radio networks. Admiral Karl Dönitz received reports of "impossible" encounters between U-boats and enemy vessels which made him suspect some compromise of his communications. [20] On 25 July 1939, the Polish Cipher Bureau handed reconstructed Enigma machines and their techniques for decrypting ciphers to the French and British. [7] Sir Harry Hinsley, Bletchley Park veteran and official historian of British Intelligence in World War II, made a similar assessment of Ultra, saying that while the Allies would have won the war without it,[8] "the war would have been something like two years longer, perhaps three years longer, possibly four years longer than it was.
