When did Germany realize Enigma was broken?
The actual revelation for the majority of Germans did not come until the 1970s when the Ultra documents were finally de-classified. The long delay in revealing them was the result of many Warsaw pact countries relying on Enigma based technologies through the 1950s and 1960s.

What might take a mathematician years to complete by hand, took the Bombe just 15 hours. (Modern computers would be able to crack the code in several minutes). Many of the weaknesses in the Enigma system came not from the apparatus itself, but from the people involved in using the code-generating machine.

Why was the German Enigma so difficult to break?
The thing that made Enigma so hard to crack with contemporary means was that the settings changed with each keystroke. If you were to sit down at an Enigma machine right now and press the “A” key three times, you would get a different scrambled letter every time.

In 1923 he set up his Chiffriermaschinen Aktiengesellschaft (Cipher Machines Corporation) in Berlin to manufacture this product, and within three years the German navy was producing its own version, followed in 1928 by the army and in 1933 by the air force.
How did the Enigma code help the Allis?
The enigma code had to be kept a secret by the British so the Germans wouldn’t find out about it being broken. The breaking of the enigma code changed the war drastically by allowing the Allis to know the Germans moves body During the war great Brittan fort in a battle called “the battle of the Atlantic”. In this battle they took over a German U-boat, inside they found the machine that was receiving the German codes. The machine was bought back to England to see if they could crack the code. A man called Alan Turing brock the enigma code after he built a machine that could decipher it. It took him 3 year to eventually break the code. The enigma code was a vital part of the Germans communication to each other. The Allis used the code to intercept the German message and find out things about their armies and strategies and what they were planning on doing. When the code was fist Brocken the message they deciphers was a bombing of British ships, the people who broke it couldn’t tell anyone that they had broken the code, they were to scared of Germany finding out that there code has been broken. If Germany had found out that the code was broken they would have changed it, England couldn’t afford Germany finding

To do this, the Allies set up a hoax. First, the Allies found German spies and told them false information to report. Then, the Allies created a phantom fighting force and gave false information via radio, which they knew the Germans were eavesdropping on. The Allied code-breakers could decipher Germany’s communications, and that is when the Allies knew that their hoax had been a success. Because of this planning, the Allies were well on their way towards victory by the time Germans realized what

However, it wasn’t long until tension started to rise up in America
What is the argument for bystanders to resisters?
A common argument in favor of bystanders’ inaction is that they would have been in greater danger and put more lives in jeopardy if they became rescuers. However, this is not a valid claim. Clearly, there is striking evidence that proves if a group strongly opposes legislation or perpetrators, then it would be harder to control the protesting group. In the reading, “From Bystanders to Resisters,” people who were originally bystanders created a strong group that opposed the Nazis. After the ordinary Germans citizens combined in a joint effort to “ [consider] ways of fighting the Nazis and building a new Germany after the war,” they “placed a briefcase containing explosives under a massive table around which Hitler and his staff were scheduled to meet later that day” (“From Bystanders to Resisters” 374).

Poles were definitely disappointed to see that despite the film only covering a short span of time, their major contribution was still marginalized.
When did the Poles crack the Enigma?
The Poles had cracked Enigma in 1931, but when war broke out and the codes changed every 24 hours, it was evident that more effort had to be brought to bear on it. And so to Bletchley came an assortment of mathematicians, military experts, historians, bankers, musicians, chess masters, and people who did the Times Sunday crossword in ink. Huts sprang up on the grounds where code-breakers worked, sweltering in summer, freezing in winter, in a haze of cigarette smoke. Others labored in centers close by, including Eastcote.
Who invented the Turing Bombe?
Chief among the code-breakers was mathematician Alan Turing, who invented the Turing Bombe, a device that turned the letters produced by Enigma into legible German. With its rows of wheels and dials, it is tempting to call the Bombe a prototype computer, but it is in fact an electromechanical device that carried out a systematic search to find combinations on the Enigma. There were 150 million million million possible settings to choose from!

How many bikers came through the gates of Bletchley?
Motorcycle couriers took the translated messages to Bletchley, whence they went directly to the War Rooms by radio. As many as 35 or 40 bikers might come through the gates in an hour. Churchill could read Adolf Hitler’s mail before Hitler did. It was estimated that Bletchley’s work shortened the war by two years.
