I had the opportunity to stand on Omaha beach, Dog Green sector. My feelings were enhanced from watching your Walking D-day series. Thank you.
Excellent breakdown and description. The first time this has made sense to me. Thanks. Good work.
Very enlightening and a job well done. A simple explanation for a very complex machine.
Polish code breakers were able to read German messages in 1932 long before the outbreak of war in Sep 01 , 1939 which was the reason of passing vital information to British and French . Names of Polish experts are - Marian Rejewski , Jerzy Rozycki and Henryk Zygalski with many others who contributed to the project of cracking the “Enigma “ - most sophisticated coding mashine of that time .
Exceptionally clever people. I struggle with crosswords.
Well done
Here is the link that says once and for all that no Alan Turing cracked Enigma. It was the Poles that did it and nobody else.

You are like a cult member. The Poles did what they did, and Turin and the 3000 staff at Bletchly park did what they did, ie reading German coded messages daily.
This is the tirle of the "once and for all video"
Heroic Polish Codebreakers set the Foundations for the Allies to Crack Engima
Foundations for the Allies to Crack Engima
This guy insolently changes dates as if it was Turing who first began working on Enigma. It was the Polish mathematicians who were presented in the video first began cracking the Enigma 10 years before Turing. Turning would do nothing without the POLES and the Brits take credit for busting Enigma. Turing would not even have known where to start without the Poles. So, it is the Poles who cracked Enigma and no some Alan Turing.
Where did I « insolently change dates »?
The Poles made a great advance with the means they had. The Bomba they made had 6 spindles for decrypting a three rotor Enigma machine. The 5 rotor Enigma would have needed a Bomba with 60 spindles.
To say Turing would have NEVER have worked out the Enigma machine is like saying we would have no notion of evolution of Darwin hadn’t published his book. People find ways.
There was a team of genii working on these problems. Turing has become the most famous but I don’t know if he was the most intelligent. Tutte worked out how the 12 rotor Lorenzo machine worked without ever having seen one.
@@WalkingDday At :6:52 you say: '' ...........but Turing at the Bletchley team cracked it anyway. The Poles came into the picture in 1929......''. No, In 1929 Turning never heard of Enigma. So, it was the Poles in 1929 that worked on Enigma and Turing began 10 years later. So, don't switch the date facts and don't give credit to the British for cracking Enigma. If you Brits had began war on Germany as you declared on 3 of September 1939 along with the French Poland would not bleed. You brag that 10 000 Londoners died because of V1 and V2 rockets. Just in Warsaw uprising 250 000 Warsaw civilians died during the 63 day battle. I call the British and French cowards. Get your video straight.
@@user-ky5dy5hl4d I did, but you are taking it out of context. This is what I said.
« To increase the strength of the cipher they added two more rotors to choose from. The operator might be instructed to put in rotors V II and III .
The German security boffins tested the machine and came to the conclusion that it was’t 100% crack proof. They added the piece de resistance. The plug board. The plug board had a socket for each letter of the alphabet. Each typewriter key was wired to the corresponding socket on the plug board, then to the rotors.
The operator had ten cables with plugs on each end. He could connect letters to other letters. If A was connected to T , typing A would send T to the rotors and typing T would send A to the rotors. If a letter had no plug in it, the letter would be itself.
The number of combinations was now 158 quintillion. That’s 158 followed by 18 zeros. The cipher was now really uncrackable. But Turing and the Bletchley team cracked it any way.
The Poles come in to the story in 1929. The Poles were proficient at decoding Russain ciphers which dated from WWI. In 1929 Jerzy Rozycki attended a cryptology course in Warsaw. He then worked in the cipher bureau with Marian Rejewski and Henryk Zygalski….. »
First....it was the Polish men....Then....it was Alan Turing....Problem solved....
RRZ (Rejewski, Różycki, Zygalski) were educated under the Prussians - in German - and they had the knowledge and experience that no-one else could have provided in the 1930's.
Touring provided the theory that RRZ didn't.
