The Chinese military and people rose up to resist and went through thousands of efforts to curb the pace of Japanese aggression, but why did a country as small as Japan have the courage to go to the ocean to attack China? In terms of troops and materials, they did not have an advantage, why did it take Chinese eight years to win, in fact, the key is that the Japanese side had the most advanced equipment at that time - aircraft, and China did not shoot down its anti-aircraft guns.
China has been passively beaten, mainly in the hands of the Japanese, at that time China's national defense equipment completely dependent on imports, in terms of performance can not be compared with the Japanese army, and at that time there were not many pilots, according to the basis of the inability to compete with it. Although the anti-aircraft guns with a range of more than a thousand meters are still powerless against the bombing of the Japanese army, for a long time, Chiang Kai-shek and Dai Kasa also sensed that something was wrong, why every time the Japanese army can avoid the defensive range, accurate bombing targets, after ruling out many possibilities, the final conclusion was drawn, that is, there was internal traitors in the army, and some people leaked important military secrets.
Chongqing bombing suffered heavy losses, countless Chinese displaced, everywhere can see the ruins of broken walls, in the face of such a tragic result, the intelligence organs of the number of hands Dai Kasa finally struck, after intercepting part of the Japanese army's secret telegram, basically confirmed that there are insiders collaborating with the enemy to betray the country, to find out the traitors has become a top priority, but cracking the code is not an easy task, no one is helpless.
At that time, China did not have such talents, and finally Dai Kasa and others could only turn to foreign experts, and finally locked their eyes on the father of the American code, yardley's process of deciphering the secret telegram was also very tortuous, and when he first took over, he had no clue, and later learned from the captive enemy personnel that the password was composed of fifty letters, and there were no more clues.
Yardley began to summarize the law according to the telegram intercepted by the military, and after repeated confirmations, he finally came to the conclusion that the Japanese used a one-time password, this small breakthrough liked many people, the frequent light and grain words gave him more hints, and finally found the source of the book code - Pearl Buck's "Earth", bombing the secret electricity officially announced the cracking.
After mastering the law of sending secret electricity, he quickly found out the person who leaked the secret, the one-armed thief, according to the results of the investigation, his real identity was an officer of the Sichuan Army's anti-aircraft artillery team, and it was because of his leak that the Japanese army evaded the defense range of the anti-aircraft artillery every time. After this incident, the military command has repeatedly launched internal investigations, which have made many of them
