      How far in the design process do you suspect the later and more obscure IJN projects such as the triple turret heavy cruiser (i.e. Zao from WoWs) were before they were put to the torch? Why is it that we have more information on certain designs/projects such as the B65 than others?

      There's only two codes I know of the that are unbreakable. One is RSA or public-key cryptography and the other is a book cypher. The book method encodes by giving the letter three numbers. The page number, paragraph and how many spaces into the that particular line your letter is. You have to have a exact copy of the book that was printed in the same year by the same publisher because in subsequent reprints the page numbers would be off. That method was used in Mel Gibson's movie "Conspiracy Theory" and they used "Catcher In the Rye" as the cypher.

    Because I'm Swedish, I want to remind about the Swedish mathematician Arne Beurling who on his own cracked the code of German telegraph line traffic between Germany and occupied Norway. In two weeks! This had nothing to do with Enigma, it was a kind of dedicated teleprompter encryption . And the dis-encryption machine he designed turned out to be simpler and faster than the German original.
    en.wikipedia.org/wiki/Arne_Beurling
    Perhaps Germans aren't that good at math? Let's enumerate the notable german mathematicians! Leibnitz. Euler, of course, but he was a professor of Saint Petersburg in the 18th century. Gauss, the incredible genius of probability theory most useful for code breaking, but he was beaten up by his school teacher for solving his homework too quickly. Hilbert. Riemann. Klein. (I wish I understood half of what they accomplished). So the Germans DID have great mathematicians. Their military leaders just didn't understand how to put them to use. Maybe their math teachers didn't beat their behinds red enough in school.

Neither way, punishing the bad boy or the good girl, the tough or the soft, did any good.
      It' does no good to beat children. Once beaten, they lose respect for it, because it wasn't so bad after all. The (tough boy) child understands that the beating is only symbolic with no intent of hurting them permanently physically. It is the THREAT of being beaten for the first time, that scary unknown, that works. Like nuclear war, a threat that only works as long as it remains an unfulfilled promise.

      Hilbert, who you mentioned, was once asked by the Nazi minister of education about the state of German mathematics, now that they had been "freed" of "Jewish mathematics." Hilbert supposedly replied that they had "destroyed" German mathematics.
      An example: there are two main mathematical central databases for article reviews, known colloquially as zblatt and MathSciNet. "Zblatt" sprang from the journal "Zentralblatt fur Mathematik" (roughly "central newsletter for mathematics") founded in 1931 by, among others, Otto Neugebauer. MathSciNet sprang from the journal "Mathematical Reviews," founded in 1940 at Brown University by Otto Neugebauer, who had refused to swear a loyalty oath to Hitler, and had been expelled. Within 10 years, the language of mathematics had shifted irrevocably from German to English.

    Amazingly, the Enigma machine was patented in 1918 by Arthur Scherbius, a German electrical engineer. It's first successful use was by the German Army in the late 1920's as a method to communicate among German manufacturers. The Germans were forbidden to rearm under the Versailles Treaty, and Enigma offered an ideal way to communicate between the Army and manufacturers that were illegally building tanks. Even though the encoded text was transmitted over normal shortwave frequencies, it was assumed the that massive number of key combinations would make it impossible for the Allies to know what the resurgent German Army was up to. The first successful attempts to break the Enigma code wasn't done by, as might be expected, the British or the Americans, but by the Poles, starting in the mid 30's. The amazing math described by Drach gave the Poles what they needed for their "Bomba", the first brute force machine to decode Enigma messages. It was the first of many built by the British and Americans.

    I think there was one historical error: Rejewski and Zygalski were not at Bletchley Park, not even informed about its existence. They still worked on cryptoanalysis during the war but were kept out of ULTRA completely (reasons not totally clear but there are suspicions them being Poles had something to do with it). Their invaluable pioneering work was later downplayed and imo it took the French spilling the beans on the whole thing to get them the recognition they deserved.

Tadeusz Lisicki reported this in Brian Johnson's book The Secret War in 1978 (a tv series was made later of it as well).
    Over one weekend while the Polish customs office was closed, the German Enigma was in the hands of the Polish military intelligence service. During that time it was studied in all details, photographed, and repacked to be sent to the German embassy the next monday, without any visible traces what happened, of course. With that information, BS4 started the Polish decyphering of the Enigma until 1939. When the Germans invaded Poland, the Poles destroyed any whatsoever evidence about what they knew or could do. As far as we know today, the Germans did not assume that Enigma has been cracked a long time ago, and they continued to use it everywhere.
    How did the Poles know that there was an Enigma on its way in 1928? According to Johnson's book/Lisicki: because the German official who got anxious to get "that packet" out ASAP, was making the Poles suspicious, just because he behaved so nervously; so that packet must be very - uhm - important ...
    This indicent was also reported by the Polish-German historian Janusz Piekalkiewicz in his last book in 1988, referring again to Lisicki; only that it happened in January 1929.
    Given the fact that the successful Enigma decryption was kept secret until 1974, it becomes understandable why all these small nice details remain unreported in most other books.

"The Ultra Secret" was published around 1974 (the series might have already been in the works when Enigma/Ultra was revealed, and a last episode added on to cover it).

    I have just seen the video. Brilliant work for sure, especially the brain melting part showing how complicated the machines to code were and how insane the work to decode was.
    When it comes to the Poles there are some factors to consider, some of them less important, some more:
    1. A number of Poles who lived in the part grabbed by Prussia in 1792 (and again in 1815) during the 1st WW worked in communication units of the German Imperial Army, one of several reasons was no local accent. German was a foreign language to them so no unnecessary and disrupting changes to the German language.
    2. Poles managed to break Red Army's codes in 1920 to such a degree they were capable to read Soviet messages faster than the units of the Red Army. This also allowed them to see through lies and deception while Red Army was gathering troops and heavy artillery in early 1920. Ironically this also worked once for the Red Army's favour because March-April offensive of Polish-Ukrainian troops was timed so that Soviet northern front in Belarus was still not ready to react to the events in Ukraine, but Tukhachevsky launched an offensive too early, in May 1920 which failed but achieved something - forced Poles to react and deprived their army in Ukraine of some key units so it was unable to stop Soviet Horse Army. It was rough for the Poles for the entire June and July duo to the fact, but again in August 1920 and September/October helped them gaining victory in this war.
    3. Poles ran rather close cooperation with several neighbouring states against the Soviets and one particular country much, much further away i.e. Japan. Cooperation with Japan included decoding Soviet codes but not only that. Cooperation with Japan is actually older than the reborn Polish state - started in 1905 earlier, mainly between Polish socialists of J.Piłsudski and Japanese intelligence services - obviously against Russia.
    It is a long and complicated subject so I'll stop here. There was even rather stunning proposal from Japan for Poland to buy 11 light cruisers from this country... in 1932 if I am not mistaken.
    Thanks again for the video!

    In this context, also Arne Buerling should be mentioned. He single handed, in two weeks time, with pen and paper only, broke the the German codes in 1940. This code was even harder to brake than the Enigma. (Siemens Halske T 52 Geheimfernschreiber). Thousands of German messages were decrypted and operation Barbarossa was known well before it happened. Actually, Swedish diplomats warned Joseph Stalin about the operation but he simply did not believe it. As far as I know, Brittish intelligence was informed that we also had cracked the codes.
    Fun fact is that Buerling later inherited Albert Einsteins office at Princeton.

      It was a little more complex than King being a Jerk who didn't respect British advise.
      Early on, he didn't have the assets to protect convoys on the US East Coast so he allowed Single Ships to sail and be attacked by U-Boats vs Several Ships being grouped in Convoys to be attacked by one or more U-Boats.
      Initially he used his limited assets to escort Troop Carriers to Halifax to be formed into convoys and escorted by Canada/Britain to the UK.
      In early 1942, his only priority was protecting Troop Ships.
      He then began to escort War Supplies in early/mid spring '42 with priority on Oil/Av-Gas to Britain.
      When he had more assets, he began convoy ops on the East Coast in late spring '42 and later in the Gulf/Caribbean.
      Without assets to protect East Coast convoys, losses would have been much higher within those convoys than the losses of non-escorted/non-convoyed shipping. Hence, no coastal convoys in early 1942.
      Historians don't give King the credit he deserves. He did what had to be done with the resources he had.
      Also, King was not directly commanding East Coast ops. That was then Vice Admiral Andrews who had to make the hard day-by-day decisions to get as much cargo as possible to Halifax knowing that many ships and lives would be lost in the process.
      The only other possible decision, in the early months of '42, was to stop all shipping on the US East Coast. That would have been Britain's Death Knell.
      Also, King had more pressing needs in the Pacific than the loss of Merchant shipping/lives on the US East Coast. There was the possibility of a Pearl Harbor type attack on the West Coast which was very real until the Battle of Midway.

    1. The tendency of German units to sign their messages 'Heil Hitler'; even better for a starting guess than 'An '.
    2. Garbo (Juan Pujol García): a Spaniard who detested the Nazis, who set up an entirely imaginary spy network to feed them misinformation, and who was eventually, after a couple of rebuffs, hired by MI6 to expand his activities in the UK.
    _It is a lot easier to decrypt a message if you have both written and sent it, and then intercepted the Enigma retransmission of the identical text._
    Garbo had the rare distinction of being awarded both an Iron Cross 2nd Class and an MBE.
    One of Garbo's fictional agents unfortunately died. The Nazis swarded his equally fictional widow a pension, which MI6 gratefully paid into their own bank account, thus reducing the burden on the British taxpayer.

      There is an optimal number of plugs for the plug board, I think it is 7 or so. When you add more plugs you actually decrease the number of combinations.
      But then again, once you have a crib and mass produced bombes to allow for parallell testing of all the 1680 possible rotor combinations in parallell (which requires bombs with 4 rotors for each of the letters of the crib, which was typically 4-6 letters) the substitution cipher of the plugboard just adds a minute or two to the decoding.

    I like how the British told no one about cracking Enigma until 30 years after the end of WW2. My guess is this is because Russia and other countries were getting examples of Enigma after the war and a lot of them made their own versions after the war. The Soviets used a ten rotor system called Fialka. By "forgetting" to tell the Soviets that they could crack rotor machines, the British would have been able to read Soviet traffic well into the 1970s. My guess is that Enigma became public after the Soviets went away from rotor machines.
    Also, I am guessing that Huff Duff (High frequency radio direction finding) was mainly used as a cover for the fact that the British had actually cracked the naval enigma.
    And finally, why did the Navy use a four rotor system when everyone else used a three rotor system? It is because they did not trust the Army encryption methods and encryption discipline after their experiences with the Army in WW1. And quite right they were too.

      Not all rotor machines are created equal. That is, just because you can break one does not mean that you can break them all. Enigma was broken because of certain weaknesses of the machine, and because of defective procedures. Without those weaknesses, and without the bad procedures, it would not have been broken.

Perhaps in the weeds for many, I found the in debth info extreemly on point and learned quite a bit about that machine that was such a vital key to German troop movement and crypto skills. God bless Turning..that weird little man became a GIANT. Well done mate.

    In 1970 I trained at Fort Leonard-wood Mo, part of our training was with a device that was pretty much a clone of the last machine you had in the photo except these had a tape feed on them so they typed out the coded message via the tape. I believe the reason behind the training was simply to give us an idea of cryptology since our MOS was Field Wireman. Some of our duties did involve the old PRC25 and 77, the latter was capable of encrypted transmission and reception with a huge add on device. I later cross trained into Landline Teletype and later Radio Teletype communications, ending up with the Communications Chief MOS when I moved on. Your video was like a trip back to my youth, thanks a million for the research and putting the video together. I love history on RUclips.

    One interesting fact that I read elsewhere was that
    A) the enigma was actually invented before WW II as a device to secure bank and economical as well as political information when sent via Telegraph..... cause every operator sending e.g. a cable to somebody at a distant branch of your bank/company/... was able to listen in.
    B) the Polish didn’t trust germany and started spying on German military communications pretty early on after WW I as in overhearing the Germans maneuvers initially in clear and then working on the subject as soon as germany started using encryption...

    The number of "stucker" wires could only be 13 maximum, as each wire connected a pair of the 26 possible letters...so there could never be 15 plug wires.
    Beyond those you mentioned, there were some other procedural flaws. One rather humorous one was that there was a suggestion that a nonsense word be added to the beginning of the message to improve security...so that they weren't all starting with, for example, "weather report" (or "ANX" as you mentioned.) "Sonnenschein" (Sunshine) was given as an example of such a nonsense word. So it turned out that a huge number of messages literally started with the word "Sonnenschein". A huge number of messages also ended with the words "Heil Hitler". Because of the A=/=A flaw, it was pretty easy to test the cypher text to see if the suspected plain text was indeed in the message.

      Lorenz was simpler it is a modulo 2 binary addition of a pseudo random sequence. You cracked it by adding together two message texts sent with the same settings which removes the pseudorandom stream and leaves to convoluted German texts the deconvolution is a room 40 type problem. This is even easier if they are the same message which given the mechanical fragility of the system seems to have happened more regularly than you might think. The key difficulty is adding the two sequences together accurately and in step without error and that needs a proper computer rather than an electromechanical machine with hardware embedded algorithms

      They are both rotor machines, but the Enigma only has 26 letter wheels,. while the Lorenz machine has three different wheels that all turn at every bit (or letter, not sure which).
      Without operator errors like repeating a message with the same settings the Lorenz would have been safe.
