If I remember right that was Coventry. The Germans were not testing anything however. They had no idea that their code had been broken. If the British had taken any extraordinary measures to protect Coventry though, that could have given it away. Therefore the British did not evacuate the town nor give it any additional air defence. That was a very difficult decision but in the calculus of war it is often necessary to balance the cost in lives now against a greater one later on. Michael Montagne This must indeed be one of the hardest decisions to make, and it was up to Winston S. Churchill to make it.
During World War II, the Allies successfully broke several German codes, most notably the Enigma machine codes, which were used for secure military communications. The work of cryptanalysts at Bletchley Park, particularly by figures like Alan Turing, led to the decryption of Enigma messages. Additionally, the Allies also managed to break the Lorenz cipher, used for high-level communications. These breakthroughs significantly contributed to the Allied victory by providing critical intelligence on German operations.
The enigma code wasn't actually broken. What happened was that one of the coding machines, much like a typewriter, was captured along with the coding book. This gave the Allied forces the ability to read the code.
The current (2012) principal allies of the Ba'ath regime are Russia, China and Iran.

Ultra was the Allied name for Enigma, a German ciphering machine which looked something like a typewriter. Since the Enigma code changed every day, it was impossible to break, but the Allies captured an Enigma machine early in the war and were able to decipher the German code. At first, Ultra would seem to have been an easy end to the war, but it was important to keep Germany believing that their code had not been broken, lest they switch to a different coding system. Therefore, some information from Ultra was acted upon by the Allies, and some was not, so that Nazi Germany would remain convinced that their encoding system was intact.

The German ENIGMA coding machine was used to communicate orders from Germany to its deployed U-boats. Early in WWII, the failure to break the ENIGMA code helped lead to significant losses in the Battle of the Atlantic. The Germans believed that the ENIGMA code was unbreakable. The first break for the Allies came when the British destroyer HMS Bulldog successfully boarded and captured an ENIGMA machine and its code books from the German U-boat U-110 in May, 1941. The capture of the ENIGMA machine significantly aided efforts by cryptoanalysts at Bletchley Park in England, where the main British code decryption efforts were being conducted. Eventually Bletchley Park was able to successfully build a computer that would decode all German Naval communications. This feat, as well as the Allies' success at keeping the knowledge from the Germans that ENIGMA had been captured and broken, led to the major downturn for German U-boats in the Atlantic. By the end of the war, German U-boat losses were 70%.
The Enigma was pretty much a complex machine that the British got a hold of. They got it when Germany invaded Poland and someone stole it from one of the deserted U boats and brought it back to Britain. This helped because when Hitler sent commands out to the U boats, Britain will also pick up the command so Britain would be one step ahead of the war plan. The only problem was when Britain found out one of their undefended cities were going to get bombed, they couldn't do anything because they did not want to let the Germans know that they had the Enigma. Otherwise, Britain would use it to find out Germany's plans and use it to attack one the areas that they are not covering.
