...World War 2 secret code breaker World War 2 marked for many of Germany's mistake and one of the critical mistakes was using secret codes for radio messages to communicate between allies. However, the meticulous work of code breakers based at Britain’s Bletchley Park cracked the secrets of German wartime communication, and played a crucial role in the final defeat of Germany. The moment Germany started using radio to communicate with its allies a narrow grave was dug, but it kept getting wider and wider, the more they used radio. Eventually the grave became wider and deeper, thus Germany collapsed and lost the war because of these mistakes. Therefore many of the allies of Britain in Europe won their battles. In this essay how , when and what will be discussed regarding the consequences for using coded radio communication. history.co.uk The Enigma story began in the 1920s, when the German military - using an ‘Enigma’ machine developed for the business market – began to communicate in unintelligible coded messages. The Enigma machine enabled its operator to type a message, then ‘scramble’ it using a letter substitution system, generated by variable rotors and an electric circuit. To decode the message, the recipient needed to know the exact settings of the wheels. German code experts added new plugs, circuits and features to the machine during the pre-war years to make it more complex. Although its basic principle remained the same. Therefore if it was hacked once...

...Extended Essay Group 3: History To what extent did breaking code JN-25 and code ULTRA give aid to the Allies in the Pacific and Atlantic theatres of World War Two? Word Count: 3746 Abstract: This extended essay has the subject of Code Breaking Intelligence. When studying the Second World War, the phrase ‘code breaking’ is not highlighted as a significant factor, so this investigation is to assess the contribution of code intelligence in the Second World War. The main question being: To what extent did breaking code JN-25 and code ULTRA give aid to the Allies in the Pacific and Atlantic theatres of World War Two? The scope of this investigation is confined to two specific codes called the JN-25 and Ultra. This is due to the abundance of codes and ciphers used during WWII. It is also limited to where, either the Pacific or Atlantic theatres, these two codes were most effectively applied to aid the Allies. Information was attained from secondary sources to create a bank of relative information to the research question. The conclusion that can be drawn from this investigation is that code intelligence did significantly aid the Allies in the Pacific and Atlantic theatres. With the assistance of JN-25 the Americans halted the Japanese in the Pacific theatre, stopping its expansionist and aggressive behaviour. Similarly, the British and the Americans, with the help of code Ultra, achieved an offensive against Germany and Hitler, plus shortening the war by two to four...
