At the Brechley Manor, in addition to Knox, the deciphering community, there is also a mathematics wizard, Turing. He graduated from Cambridge University and relied on his research on cryptography after the war. He became one of the pioneers in the era of electronic computing.

First of all, they started with the development of a machine that can imitate or explain every "dummy mystery" of the German Defence Force, so that it can launch all the coding procedures that are frequently changed when the main command of the German army is issued day and night, and when the adult orders are issued. After a difficult attack, the British finally made the machine with the above functions and named it "bomb."

At the end of 1939, the "bomb" deciphered the German code, and the British were ecstatic. Since then, the German secret plan and action plan has been continuously transmitted from the Brenchley Manor to Colonel Menzies, and then directly to Churchill's desk. In fact, most of the German actions during the "World War II" failed to win the British, but the British have always concealed the source of intelligence, and have never caused doubts from opponents.

On July 2, 1940, Hitler released the first "Sea Lion" combat plan, which is also the British local landing operations plan. At the beginning of the campaign, Churchill and the Air Force staff learned most of the German Air Force – sometimes even all of them – through “super secrets”.

In response to the command of the German Air Force Commander Goring to seize the air superiority, the Royal Air Force has developed a plan to concentrate its superiority against the enemy. Since the number of aircraft of the British Air Force is not much in Germany, the fighter squadron and the main defensive forces can only be concentrated at the appropriate time, in the right place and at the appropriate height to deal with the enemy's main attack power. Relying on early warning radars and deciphered German military intelligence, the Royal Air Force can always take advantage of the arrival of the Nazi Air Force to accurately intercept the interception, without the need for time and space patrols to guard against German raids - the British Air Force has greatly reduced the pilot's physical consumption and gasoline Wait for strategic material consumption.

On August 13, 1940, over Sussex and Kent, 80 German "Donil 17" bombers, and a larger number of "Junker 88" dive bombers, flew to the British hinterland and coastline to carry out bombing missions. Due to the dense clouds in the sky, the German escort fighters could not take off as planned, and the bombers had to attack alone.

The British Air Force Command had already known the German action plan in advance. When the German plane was found on the radar, it immediately launched an operational plan that was already ready. In this confrontation, the German Air Force lost a total of 47 aircraft and more than 80 were injured. The British Air Force lost only 13 aircraft.

So actually in the WW1, the cipher of the German military should not be posted. It directly results in that the cipher of WW2 is deciphered.
