Absolutely fascinating from start to finish, This should be shown in the school's today to show what a brilliant country Britain is instead of putting this great country down.

Thank you, Daddy, for your service on the USS Randolf, still going at 96 yrs old ❤

Bletchley is a brilliant place to visit. Loved it all. Amazing what they achieved

The Enigma was broken in 1932 by three Polish mathematicians: Marian Rejewski, Jerzy Różycki and Henryk Zygalski, who were employed by the Polish military Cipher Bureau. The first Polish copy of the military version of "Enigma" was built in the "Ava" factory in Warsaw in 1933. The process of putting the elements together took place in Pyry near Warsaw. From then on, Poles could read German military correspondence. In 1939, Poland handed over the Enigma documentation to the British.

A great documentary and very absorbing. Very sad how Turing was treated after the war. Instead of being a hero he was victimized. Why didn't the hierarchy who were involved with Bletchley do anything to help him?

Ah this little machine was genius. Glad it was figured out layer by layer. This is an amazing video, thank you

Turing, one of the greatest minds on the last century. Doomed by the narrow minds of his contemporaries.

Everyone who is a major in Computer Science knows the famous Turing Machine. He's the father of Computer Science.

Marian Rejewski broke the Enigma code. Thanks to the achievements of cryptologists and possession of the commercial machine and documents provided by French intelligence, Poles started work on building a copy of the Enigma soon after. To put that into perspective, on 30 January 1933, one month after the code was broken, Hitler became chancellor of Germany. With the second world war looming, Poles had to share their knowledge about the Enigma with British and French colleagues. During a meeting in Pyry, near Warsaw, in July 1939, Rejewski and his colleagues demonstrated how to crack the machine and gave each allied side a replica. This allowed Alan Turing to continue their work at Bletchley Park.

That's actually one of the best documentary I watched about the enigma machine! From the beginning , it gave a great insight on how it actually came to be, how it worked ( genius engineering ) and how we deciphered that thing. We should always be grateful for Alan's Turing work, developing the first modern computers. one of those beautiful mind that we lost because of human greed & homophobia. keep up the great content 👊

From the United States, thank you Bletchly.

I always knew the basics of the story. But watching this video was the most enjoyable piece of anything I ever watched. Knowing what was at stake, and the little details just made it so much the better. Those folks at Station X are heroes that should be remembered forever, along with the gents of the Royal Air Force. I just love everything about England and just such a remarkable country over time. To know they were at their knees and made it just gives me goosebumps. Had Hitler been more competent, the war could of turned out much different.

Bletchley Park, the location of the top-secret Ultra code-breaking team described by Churchill as “My geese that laid the golden eggs and never cackled.”

I know that the "Officer Class" will not like it but contribution made by Tommy Flowers was magnificent, so much so that his efforts have been subdued.

I read a lot of books about WW Two and it's frightening how many things happened that if they hadn't WW Two might have been lost and the world been ENTIRELY different. Even the breaking of the Nazi code depended on lot's of separate things that very well might not have happened the way they did. Reminds me of the proverb "For Want of a Nail".

a documentary on who and how enigma is created would be wonderful

Years after the war ended the benevelant UK government decided Turin should be pardoned. My God, why didnt they do this when the man was alive? Did they think this made them squeaky clean. That they did the right thing. Bloody hipocrites. RIP Alan. Blessings from Argentina.🌹🌹🌹

This is the best documentary video I’ve seen in a long time. And that it’s two hours is even better.

Don't forget Poland got the first enigma machine and 3 Polish scientists/mathematicians did the ground work.

That Turring cat was a human computer . Next level Genius

A fascinating documentary on once great event in history.

What a documentary! I cannot stop watching. All my love for Alan Turing (and somewhat for Churchill as well).

Brilliant documentary.

Very interesting doc still relavent today. Thank you for sharing and keeping these stories alive before they are gone

Interestingly, here in Ontario, Canada, we had Camp X. Ian Fleming was trained here.

Absolutely fascinating!

BRITTIAN NEVER STOOD ALONE. Canadians and Australians fought since day one.

Flower (Collosus), Welchman, Tiltman, Newman, Tutte (and the Poles) all had remarkable minds and huge impacts. It is odd Turing gets so much credit and not the others.

Perhaps because I was always a complete nullity in Maths, I really wonder at how the human mind managed to break the Enigma code on the basis of mathematical and other calculations

I love this documentary. Sounds fascinating like solving a puzzle. My puzzle here is : why there is English subtitle in the whole documentary except when German was spoken ? 🤔🙄

a documentary on who and how enigma is created would be wonderful. A fascinating documentary on once great event in history..

I Appreciate the help

Hut 33 is a hilarious comedy about Bletchley Park, well worth a listen.

Always sometimes they use fraction ratios to play certain gravity layers to how they understand the pyramids or the atmosphere that they produce inside a different depths

What about my hero ? Tommy Flowers ? He converted Turing's theories into machine that worked !

What is missing is the crucial work of Elizabeth Smith Friedman who developed a method of code breaking with her husband who worked for American Intelligence at the time. She found a flaw in the Enigma coded messages which led to the downfall of Hitler’s top SS man whose code name was SARGO. By breaking the Enigma code, she tracked SARGO to South American where he had set up a second team of spies. Broken for the second time, SARGO went underground and would never organize another spy system again. South America broke ties with Hitler and Japan and became an ally to Europe and American. Elizabeth Smith Friedman’s work was classified and sealed. Herbert Hoover took all credit by stamping all her team’s deciphered messages with the FBI seal. It wasn’t until 2008 when her file was declassified that the world found out the truth. Her work was groundbreaking and her methods still applied today. She is worth looking up!

Great story of Station X Intell, helping to save many lives.◆◇◆

Gosh how brilliant are the British. They invented the modern computer as we know it today. Brilliant. RIP Alan Turing .

Did they destroy him or did he destroy himself. Isn't someone who saved other people's lives enough for someone?

Excellent documentary but why no subtitles when German was spoken at the most crucial moment of the U-Boat surfacing?

Great documentary destroyed by way too many KZfaq commercials.

The Hackers' Dictionary includes the adjective "bletcherous" which all by itself sounds severe enough. But I presume that it right appropriately alludes to Bletchley ParkQ

interesting!!

Shame they didn’t have captions for the German language pieces

So on your side of the country how many did you catch pulling the rotation of the atmospheres and energy streams to take out weight material or to pull someone else's technology outside in

70 years after his death, I'm only now learning of Alan Turing. THAT is a tragedy.

The millions of lives saved by the brilliant Alan Turing and his incredible team, only to kill himself because he was gay. The British government were instrumental in his death and a lovely way to honour and show your appreciation to this brilliant mind and man. He was offered chemical castration or prison, and took his own life in 1954. Shameful way to treat a real hero by people who got what they want and once they did, simple threw him away. Thank you Alan, absolute legend. May you forgive and forever R.I.P

What a gem of a video!

Very good video. When the extra wheel was added, did the Germans not notice? Similarly when they could read it again, did they not notice?

It sounds like the same process they use to break the code in games and understand random number generation to manipulate the seemingly random odds. Some people are just too smart.

In perspective, it achieved little because UK wasn't even predominant in the war. Russia and US took the lead in the war. Also, thanks to the secrets of UK, US and Russia fought without knowing about the decode of Enigma.

Bletchley Park and the Enigma Code was such an importantly successful endeavor for the Allies. Just think of this one element missing and how much harder it would have been for total success in defeating Hitler. Besides, we saw the introduction of the modern electronic computer. Great learning. Enjoy. Thanks.

Makes you realise what both sides went through and how much we owe to the forces in the war ...

@16.00 "What about if they'd been stupid enough to just use ABCD..." The Nazi equivalent of using "Password" to sign in.

I agree with the following correction, about Polish people breaking the code first. There were several,AIAIK, several german codes

Heroes!!!❤❤❤

Polish criptologists decoded Enigma in 1932 and at the verge of war decided to give British all they have achieved including enigma and computerized “ Bomba “ which helped speed up the process of reading German communication traffic . All that helped British as a fundament to create “ Ultra “ . Credit goes where credit is do .

As I understand it the people who worked in Station X were still bound by the Official Secrets Act more than 30 years after the war ended.

Its a strange world we live in where Colossus never existed, that is until 30 years after the end of WW2.

I really identified with David Baum who found that important letter but had no idea what said BECAUSE HE DOESN’T SPEAK GERMAN; I don’t speak German either so I would have appreciated SUBTITLES IN ENGLISH whilst the German guy was speaking!!! To quote my teenage son DUH!

Hydraulic pressure gravity's pressure and directional flow

To know what spin cycle they're using

I heard one of the Cambridge 5 was part of this

Pumps direction

Because of the way they would have technology built now anytime they would fly up in space they would have this rotation being pulled so in my opinion they wouldn't even be able to get out there far enough something would always be turning inside of their gears against them

Something that's never mentioned in any of these documentaries about the enigma was what kind of code were the British using and was it in any way readable by the Germans?

I never did manages the Time 's crossword !

Turing’s was a troubled life, betrayed by the country he saved, but he faced his infamous prosecution with amused fortitude.

It would be great if there were subtitles for the German language interviews

The barracks, or huts, as they were called, where the codebreakers worked were not heated. That is, except for some, which were said to hold valuable cargo. Those were the huts where the Americans worked.

Which way is your hydraulic pressure

Too bad they destroyed Alan Turing for simply being gay.

Best things ever know...

They couldn't get a shot of DC b roll without a jet liner flying thru?🙄😅

Old school , best brains .

No subtitles when the German guy was talking? Seemed kinda important. 🤷🏻‍♂️

My bad, 1:37:40 good old Tommy

Bletchley Park created a more advanced machine which was based on a Polish invention called "bomba" and a Polish system/machine which included only few "bomba's. These initial inventions were fundamental.

The best brains !

When brains were brains !

So also I'm one of the understandings I've seen with our government they align front desk and the public to fill out 1/0 as part of the representatives of their taxes and then it made it look like the consensual bases is always being recorded as the the public stealing or another country stealing

I'm amazed by the lady at 08:32, she must be of great age but she still looks like she's in her early sixties at most.

The German needs caption at 53min. He goes on and on.

Does the word duh mean anything to you? *Imagine the hand gestures.

Has this man had an official pardon from the government yet?

This just goes to show that the WW2 generation really was the greatest general ever. Both in Great Britain and the U.S. All the preceding generations have, and are, falling short.

The Sigma machine was cracked by Turing using an early computer, right?

Brilliant documentry

Anyone know how old this Doc is? Those interviews must be 30 years old. But the Doc itself feels modern.

Sad 😢

So much was achieved by so few, for so many.

in fact, germany was going sideways after moscow, backwards after stalingrad. the war was decided without reference to events in britain. from here, it looks like germany was hopelessly out-classed from the start.

Trev me boy, that was a good visit you took us to. A slight side-track, I have a question, re. renting m/bikes. Yes of course things will come at you from all angles but is bicycling also prone to the same dangers. Do you have any experiences that you would like to share with us? Thanks for your never ending positiveness and entertainment.

The stew went west !

You should do one on how one dead british officer helped win ww2

I found out i was born in the same house as code breaker Sir Harry Hinsley.

too much subject between the ads!

Hedy Lamar and friend helped in the submarine, boucning frequency from bomb to bomb, something like that

Some people would say that the American War Industry was responsible for the Allied victory...that was true towards the end of the war. But at the beginning of the war (1941) when the German and Japanese codes were broken that helped turn the war in the Allies favour.

What did it look like
