back to article Cryptography is the Bombe: Britain's Enigma-cracker on display in new home

The UK National Museum of Computing will open its new Bombe gallery this weekend at Bletchley Park in Milton Keynes after a successful crowdfunding campaign to put the WWII code-breaking machines on display. "We even hope to have a Colossus operator veteran present so that they can exchange notes – something they could never …

        Oh, you mean the Poles, such as Marian Rejewski, Jerzy Różycki and Henryk Zygalski who actually broke Enigma? Then some people built machines to automate their brilliance.

        The Poles never get sufficient credit for their work on Enigma.

          The Poles never get sufficient credit...

          Actually, I don't recall reading a single history of the GCCS work that didn't start with the Polish work. So I think they do get due credit. Realising that purpose-built machines could attack weaknesses in machine-generated ciphertext was a major insight. However, their relatively simple Bombas worked against a relatively simple form of Enigma; it got precisely nowhere against military-grade Enigma as used during the war. Turing's Bombes were a good deal smarter.

            Re: The Poles never get sufficient credit...

            The Polish contribution is written into all the material and they have a really nice memorial piece of art at Bletchley Park and the guided tours all make a point of stopping there and emphasising their contribution. So that "unacknowledged" bullcrap can stop.

            But Bletchley Park wasn't just about a few boffins reverse engineering the enigma, it was a big campus with thousands of people for industrial scale processing of encrypted messages that were feeding in from a network of listening stations. During the was the various types of enigma changed and had to be cracked and re-cracked as the rotors were added and the stecker boards etc. For periods of months during the U-boat blockade BP was blind to naval enigma and needed combat personnel to capture code books.

            So it wasn't just a case of being handed the decryption method before the war and happily reading off all the communications.

              Go to BP, and actually see what is on display before complaining.

              It's a worthwhile day out.

    Do I detect a subtext that Bletchley Park Trust kicked the Bombe out ?

    What are those guys on ?

    Seems like the TNMOC vs BPT dispute carries on simmering with much bad blood, just kept out of the public eye.

    >>The Bombe at Bletchley today is a replica, the originals having been destroyed as part of the post-war effort to keep Bletchley Park's codebreaking a state secret.<<

    Spooks giving up something that useful? I'll put money on there being a working set in GCHQ's basement, next to an original Collosus. I believe we did refurbish & sell on Enigma systems after the war.

      Re: State Secret.

      The story is that Churchill et al wanted to keep secret the fact that we broke Enigma, et al, as we knew the Russian's had collected a load of the machines from the Nazis at the end of the war for their own use.

        "... the Russian's had collected a load of the machines from the Nazis at the end of the war for their own use"

        Not only the Russians. Many of our European allies continues to use Enigma machines after the war, as did a number of commercial companies.

        Part of my father's job in the late 40s was intercepting encrypted military and commercial transmissions from ships in the Med on behalf of the supposedly decommissioned Bletchley Park 'monitoring station'.

        It's worse than that. The UK government sold enigma machines to some of its "allies" to keep an eye on them.

          Why's that worse? Of course you spy on your allies. If you think GCHQ doesn't take a look at US Government comms then you're sadly mistaken.

    A conspiracy theory is born

    What's the likelihood we built and sold "used" Enigma machines to Stalin, then kept the old codebreaking systems going and pretended we had destroyed them just so that Russian spies could discover the "secret" of their destruction?

    1. Yet Another Anonymous coward Silver badge

      Re: A conspiracy theory is born

      That would be ridiculous - Stalin had so many agents in British intelligence that he would have known instantly.

      Instead we sold them to all our Commonwealth friends and Non-US Nato allies, with a big sigh that it was such excellent German kit that we had never been able to break it.

        Many "commonwealth friends" worked in Bletchley Park against Enigma, so I reckon some of them might have noticed.

    When?

    Germany invaded Poland in 1939 not 1938.

    1. Captain Badmouth

      Re: When?

      Possible mix-up of dates. I seem to recall that the Poles had early warning of invasion due to being able to decrypt some Nazi signals, so got out early- 1938 perhaps?

      1. bazza Silver badge

        Re: When?

        The Polish gave their work to the British more or less as the final act of their government before being overrun by the Germans. It was a close run thing in the scheme of things.

        As well as being a marvellous technical gift, what it also gave us British was a hope that a machine based decrytion effort was plausible (indeed, the Poles had done it). In war, the gift of hope is worth a thousand battleships.

          The Polish gave their work to the British...

          (and the French, but that didn't help much)

          The British, by way of thanking the Poles, excluded them from the Bletchley operation, feeling they couldn't be trusted.

            There were many exclusions on the grounds of nationality, not just the Poles. There were people of German ethnicity in Poland, Pomerania and other border areas (see the GDansk/Danzig situation / Prussia etc) so the exclusion necessarily had to be general. It's unfortunate by not "by way of thanking..."

    I'll be there a week on Saturday.

    For the TNMOC BBQ.

    I stumped up some Dosh to help get the Bombe moved to Block H.

    Well done to all those who moved it. By all reports it was quite a squeeze to get it through the door.

    Have more than one of these on me.

    i was up there a few weeks ago, the first day the bombe was on show to the public, completely by chance.

    its a great day out, went for the guided tour of the full museum and was the only one on the tour so got huge value out of it.

    highly reccomend it to anyone with even the passing glimpse of an interest in technology and its history - so much more than just the colossus and enigma stories, truly impressive to see most of it still working.

    something pleasingly english about a museum with a Cray super-computer next to a Crazy Taxi arcade machine

  14. Andy Taylor

    Couple of things

    Firstly the Bombe isn't really a computer, it's an electro mechanical Enigma emulator.

    Secondly, Block H was built for Colossus machines 5-10, not Bombes.

    Bombes were housed in various huts (mainly Hut 11) and later at other locations near to Bletchley.

  15. unix.beard

    Careful now!

    If you go to Bletchley and want to see this, make sure you go into the National Museum of Computing, and not into to Bletchley Park. They are on the same site, but are two separate attractions with separate admission!

    wartime atmosphere

    bad scanty food, casualty lists in the paper, frequent bombing raids?

    With all due respect to those who served, I don't get the re-enactor thing. Fair numbers of my countrymen dress up in blue and gray to fire off black powder blanks at one another as if it were 1863 again, and I don't get that either. Should I be reassured that we are not uniquely demented Over Here?

      Re: wartime atmosphere

      England's own civil war has its re-enactment society: http://www.thesealedknot.org.uk/

      And you will find plenty of medieval jousting displays at big old houses in the summer: https://www.knightsofnottingham.co.uk/joustingevents.html

      It's just people who are interested in history putting on a show.

      I don't get golf at all but some do and that's fine by me.
