Was ULTRA a military 'operation'
Sorry to be pedantic, but .....
Is there a definition, in this main topic's context, of 'operation'? I had supposed that the term would be more limited and thus exclude ULTRA (though not questioning ULTRA's importance). If not what else can be added? PLUTO?
ULTRA was the designated title of the work and refers to the fact that the British Security Classification was RESTRICTED, CONFIDENTIAL, SECRET and TOP SECRET. Something designated ULTRA was in fact very much handed out on a need to know, eyes only information and was higher than anything designated TOP SECRET. As it was not a military operation in the sense that Operation Husky or Operation Overlord were, it was nevertheless information garnered via the Ultra de-crypts that enable military operations to proceed at a reduced or minimal risk. ULTRA information when passed to operational commanders was always done so in a manner that ensured they did not know the source of the information. The NAZI's as a result never discovered that their Enigma and Lorenz traffic was being decoded and read - they knew that it would be read but were always assured when tests showed that it was impossible to break. Incidentally the US Navy never captured an Enigma machine - that is a dream of Hollywood. They were made aware that Britain was reading Enigma Traffic. Imagine the scene if they had been made aware how they would have bragged on TV that they were reading Enigma traffic and convoy XYZ had got through because they had read the traffic. The Kreigsmarine would have immediately changed the settings making the whole thing unreadable and convoy shipping lost, the NAZI's could have conceivably won the war. As it is the reading of the Enigma and Lorenz codes is calculated to have shortened the war by about 2 years. — Preceding unsigned comment added by 22.214.171.124 (talk) 15:37, 25 October 2013 (UTC)
- Dissemination of ULTRA intelligence was definitely a military operation, although managed at the top level by MI-6. SV1XV (talk) 18:09, 26 October 2013 (UTC)
- The top level of UK classification during World War II was MOST SECRET. TOP SECRET was the American equivalent which the British subsequently adopted. 126.96.36.199 (talk) 17:25, 17 December 2014 (UTC)
Why in the world is this the default "ultra" page?
It's so... random and obscure. That would be like having Car redirect to a documentary called "Car" instead of the article about motorvehicle. What the heck? 188.8.131.52 (talk) 13:06, 13 July 2011 (UTC)
- Because it's the primary topic for "Ultra" -- it's not obscure to the readership at large. See Talk:Ultra (disambiguation)#Requested move -- JHunterJ (talk) 14:03, 13 July 2011 (UTC)
I have moved this from the article as it is more appropriate here. It was inserted by Grapestomper9. I'll leave a note at their talk:
It should be noted in this article that of all people associated with the sucsess of Ultra, Alan Turing by far tops the list of its most important contributors. Among other brilliant methods of cracking these codes, Alan Turing invented what can only be described as the very first electro-mechanical "high speed" computer. Most involved with Ultra at the highest levels would say that without Alan Turing the Axis would have won the War. --John (User:Jwy/talk) 00:47, 21 June 2013 (UTC)
Without Alan Turing's input in to the design of the Bombes the next step could not have been taken so rapidly. That next step was the development of Colossus to read the Lorenz Code used by the NAZI High Command to communicate Hitler's orders and response to those orders. — Preceding unsigned comment added by 184.108.40.206 (talk) 15:24, 25 October 2013 (UTC)
Did the Germans Not Suspect?
Winterbotham stated, IIRC, that one reason the 1944 Ardennes offensive (Battle of the Bulge) took the Allies so much by surprise was the Germans relied on landlines and messengers to give orders; a radio silence was imposed. OTOH, the Allies had come to rely on Ultra (which supplied no information) so much that they went so far as to discount pilot reports and other intelligence reports of a troop build-up. — Preceding unsigned comment added by 2602:306:CF99:1470:C438:7EAE:3832:58A7 (talk) 10:39, 28 October 2014 (UTC)
Churchill, King George VI, and "It was thanks to Ultra that we won the war"
In case you've wondered whether Churchill really said to King George VI, "It was thanks to Ultra that we won the war" – in particular, would the King even have been aware of the 'Ultra' codename? – with the assistance of some others I did some digging into this. The statement is weakly sourced in its several occurrences on WP, usually to an unlinked "Cited in the Imperial War Museum's 2003 exhibit 'Secret War'" (the only thing I find there now is this page which does not suggest that) and sometimes to this History Channel page.
However I believe the root source for this formulation is Anthony Cave Brown's 1987 book "C": The Secret Life of Sir Stewart Graham Menzies, where on page 671 he wrote:
- ... at the end of the war. Churchill told King George VI in Menzies's presence that "it was thanks to Ultra that we won the war."
As it happens Anthony Cave Brown didn't have the greatest reputation for accuracy – see for example this Guardian obit from 2006. In this case, he footnoted this statement (footnote found on page 812) to Gustave Bertrand's Enigma ou la plus grande énigme de la guerre 1939–1945, page 256, published in France in 1973 (and the first book to really break the secrecy around Ultra, a year before Winterbotham's).
The statement in the Bertrand book comes at the end of a short passage asserting the importance of Enigma-derived intelligence for the Allied victory. The text there is:
- Sans parler de cette entrevue historique, la guerre finie, où Sir Winston Churchill, présentant à S.M. George VI le Chef de l'I.S., prononça ces paroles; qui m'ont été rapportées par le général Menziès lui-même:
- « C'est grâce à l'Arme Secrète du général Menziès, mise en œuvre sur tous les Fronts, que nous avons gagné la Guerre! »
This can be translated to something like this:
- Not to mention this historic meeting, after the war, in which Sir Winston Churchill, presenting to H.M. George VI the Chief of the I.S., stated these words; that were reported to me by General Menzies himself: "It is thanks to the secret weapon of General Menzies, put into use on all the fronts, that we won the war!"
So it's clear that Churchill didn't use the phrase 'Ultra' and that Anthony Cave Brown didn't either accurately or fully replicate the quote. I have now done so in this article, putting some context before it to briefly explain who Menzies was.
But aside from that, to write as a straightforward fact that Churchill said this, is a bit risky. This is not something that was written on a document that has now been declassified, or something where there was a disinterested witness to the conversation who subsequently described it, or even something where we have the dates of the conversation or its later relating. There are a lot of potentially weak links in this chain: Churchill could have been overenthusiastic in the moment, or exaggerated the importance a bit to flatter Menzies; Menzies could have exaggerated the conversation, or even fabricated it; Menzies could have misremembered it when relating the encounter to Bertrand, or could have exaggerated it to play up the importance of Ultra to Bertrand so that Bertrand would feel his contribution to breaking Enigma had been important; Bertrand could have exaggerated it or misremembered it by the time he was writing his book; or things could be lost in translation.
Or, of course, it could very well be that Churchill said it and meant it and that it was accurately rendered by both Menzies and Bertrand. But given the length and nature of this chain, I think it's better for this article to say "Winston Churchill was reported to have told King George VI ..." rather than the previous "Winston Churchill told King George VI ...".
