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, it could be done again since the principal mechanics of the machine remain nearly identical to the original. edition.cnn It is thought that it’s the British who decrypted the Enigma codes but funnily enough it wasn’t the British’s who first to break the enigma codes but it was actually Poland. Close links between the Germans and Polish engineers after the invasion allowed the Polish Cipher Bureau to reconstruct a prototype of the Enigma machine. In 1939 while the Germans were busy focusing to invade other countries they had forgotten to keep heavy surveillance on Poland. The initial man power kept decreasing because Hitler was trying to invade countries to fast for German allies to keep them under surveillance. Therefore Poland realised that it had struck gold and this would be the only chance to get out of Hitler’s regime. bbc.co.uk “Poles shared their information with the British, who in turn established the Government Code and Cipher School at Bletchley Park in Buckinghamshire. Mathematicians and intelligence experts, with the help of primitive early computers, began the complex and urgent task of cracking the Enigma code.” legacy.history.co.uk Although the experts at Bletchley first succeeded in reading German code during the 1940 Norwegian campaign, their work only began to pay off meaningfully in 1941 when they were able to gather enough evidence of the planned invasion of Greece. Therefore it was extremely beneficial for the Western Allies facing hardships in the United States. Ultra played an important role there for the Europeans to take a victory. Ultra intelligence had an effect on several operations during the war from the invasion of Crete, the campaign against Rommel in North Africa, and, perhaps most important of all, during the D-Day landings.

Ultra , Allied intelligence project that tapped the very highest level of encrypted communications of the German armed forces , as well as those of the Italian and Japanese armed forces and thus contributed to the Allied Victory in Europe. Britannica.com
“Ultra allowed the Allies to learn that their dummy preparations against Calais had been taken seriously by the Germans and, once the Normandy landings had begun, the Allies knew the location of almost all the German units in the area”. theiet.org

The allied victory in Europe to this day heavily relied on Bletchley’s experts who focused upon breaking the codes used by German U-Boats in the Atlantic.
“In March 1941, when the German armed trawler ‘Krebs’ was captured off Norway complete with Enigma machines and codebooks, the German naval Enigma code could finally be read”. historyinworld The Allies could now discover where U-boats were hunting and direct their own ships away from danger. This would be mean more ammunition, better health care services and more men. A U-boat can only remain submerged only for brief periods at a time so the Nazi party needed exact location. The Nazi party also wanted Europe , Britain and all its allies to be isolated in the field. Therefore majority of the British ships would be targeted as first preference. dailymail.co.uk
“ Hitler wanted them to starve if he could” he was extremely ruthless against any allies of Britain. historyinworld
“German armed trawler ‘Krebs’ was captured off Norway complete with Enigma machines and codebooks, the German naval Enigma code could finally be read. The Allies could now discover where U-boats were hunting and direct their own ships away from danger”. telegraph.co.uk At one stage in 1942 when the German codes were paying off, Hitler was taking out 5700 British ships a year. That is fifteen North Atlantic ships a day but after the codes were broken Germany was only destroying 510 ships a year. This was a drastic change in figures and clearly the codes were paying off and the sudden rise in Europe’s victories against Nazi also increased. (Refer to fig 2 ). nytimes

Conclusion
The full contribution of intelligence to the winning of World War II is clear only now , after nearly 60 years after the war. There were many sources used to gather intelligence arguably to this day it is known that if the German codes were not broken and intercepted the war in Europe would be a lost. The experts at Bletchley played a crucial role to take Germany and the Nazi party down by intercepting the Enigma codes. Therefore the British ships could now move without fear of being targeted
