If there was a mole on the team before, how did you find out?

In the large-scale anti-Japanese drama "The Battle of Defending Changsha", Ke was originally a very capable and patriotic Shanghai beauty. She became an important officer of the theater command at a young age, wearing the epaulettes of the lieutenant colonel. Unfortunately, she was caught by Japanese spies and became a shameful spy. The consequences of selling military intelligence by spies are very serious, which will lead to the sacrifice of countless soldiers in front, and it is Lu Yunduo, the intelligence director sent by the military system, who finally finds out Ke Lijuan. This was indeed the work of the military system during the Anti-Japanese War.

This bridge is actually fictional. In the real war history, the information leakage of the second Changsha Battle was not because of the existence of a mole, but because the Japanese 1 1 telecom class deciphered some telegrams of Xue Yue, which was also caused by the untimely password replacement of the whole national army at that time. But it basically reflects the process of finding the mole. First of all, the commander and the chief of staff clearly felt that all the movements of the enemy were targeted. For example, 10 troops were ambushed as soon as they arrived at the battlefield, and there was no opponent in the world who knew the Oracle, so the combat deployment must have been leaked.

And this situation not only appeared in a unit of Li Yutang 10 Army, but also at the end of the 74th Army. That problem must have come from the theater command. According to Lv Yunduo's judgment, the key departments that can grasp the overall deployment of troops are nothing more than the War Department, the Telecommunications Department and the Logistics Department (it is easy to judge the distribution of troops from the quantity and location to distribute and transport ammunition). Then there is the investigation. All the staff working in the above departments were screened and investigated one by one from the aspects of information content and quantity, contact with the outside world and past history. The most likely suspect will be depicted.

Then there is secret surveillance or temptation, such as deliberately releasing false information to identify them one by one, and taking evidence from the enemy's reaction or possible information transfer, because information transfer is a necessary link. Not many people can fully grasp the top secret information such as the deployment and transfer of troops in Changsha Battle, so it is not difficult to check and confirm.

In the end, Ke was exposed and killed by Xue Yue on the spot. It's a pity that a beautiful woman with good nature has embarked on such a road of no return for the safety of her family, but it is not worthy of sympathy. More officers and men will die in the front line, so what about their families?

During the Anti-Japanese War, the most successful anti-espionage actions of the military government were the case of Huang Xun, the secretary of the Executive Yuan, and the case of a one-armed thief in the Chongqing bombing. These two groups of spies caused serious losses to the Anti-Japanese War, especially the latter. From 1939, the Japanese air force in Wuhan carried out "indiscriminate bombing" on Chongqing, and the Japanese bombers entered no one's land every time. At that time, the anti-aircraft guns equipped by the national army had a range of 12000 meters, but Japanese planes could fly above this height, making Chongqing's air defense firepower useless.

What is even more ridiculous is that Chongqing is a misty mountain city. The navigation and observation equipment of military aircraft is far less advanced than that in the 1940 s, and most days of the year are not suitable for bombing. But the Japanese can always fly in on time on sunny days, so it is almost certain that there is a mole in Chongqing's air defense forces. Because only Japanese agents are under the guidance of the ground, it is impossible to master such accurate information, and the military system regularly intercepts the secret messages sent to the Japanese aggressors in Wuhan, but it is difficult to decipher the contents.

In desperation, Chongqing hired American cryptographer Adrian to work in the "darkroom". Yardley and his assistants put all the secret telegrams copied by the military telecommunication department together and summarized them. After repeated research and translation, it is found that the mole's code name is "one-armed thief", and he uses a set of "infinite codes", and it is concluded that this is a set of book codes, and the original version must be an English novel, which is characterized by the fact that the first word on the first 100 page is goin, which makes Yardley very close to the truth.

After investigation, the unified action department of the military region suspected that an officer of an anti-aircraft gun unit of the Sichuan Army was a bandit, but he could speak fluent English (most people could not read English novels). Conspired by the puppet government of Wang, he colluded with Hull, the German consultant of Chongqing government, to form a spy network and provide information to the Japanese army in exchange for huge rewards. The Japanese army used this information to bomb Chongqing accurately, and the lives and property of Chongqing soldiers and civilians suffered heavy losses.

Adrian ventured to take his girlfriend Xu Zhen to visit the one-armed robber's home. With Yardley as the cover, Xu Zhen finally found an English book with characteristics in the study: The Good Earth, a novel by American woman writer Pearl Buck. Facts have proved that this is beyond doubt. After being able to completely decipher the code, China Air Force launched an ambush in advance according to the secret telegram sent by the one-armed thief, which dealt a heavy blow to the Japanese aircraft formation that came to bomb. After that, the military closed the net and arrested all spies such as the one-armed thief, waiting for them with ruthless bullets.

"Huang Xun and his son case" is well known, so there is not much pen and ink. They leaked the information that China's army was preparing to wreck and block the Yangtze River, so that all Japanese ships in the middle reaches of the Yangtze River escaped from Jiangyin fortress. But that was an urgent decision made by the "Supreme National Defense Conference". Few people knew it and it was not difficult to investigate. On the eve of the fall of Nanking, Huang Xun and others were shot, and the sinners of these ethnic groups deserved to die.

How to find out if there is a mole in the army? The lonely hero gave the best answer.

In recent years, in the war dramas reflecting the Anti-Japanese War of the New Fourth Army, The True Color of Heroes is an excellent work. In this play, Hu Jun, as the head of the wide lane, turned a regiment of the Puppet Army into a brave and United New Fourth Army. The plot is closely related, except that the width of the driveway is too wide for Gao Daquan, which seems to have no shortcomings.

Infernal affairs boss only tells undercover trading places, and when the police go, they know that undercover is a policeman!

There is a simple and direct way to find the mole: the mole is bound to reveal information and secrets, and only a few people have access to secrets. After the scope of suspects is determined, they will deliberately tell these suspects different false secrets. According to the enemy's movements and the people lurking in the enemy team, we can find out what specific information the enemy has got. We just need to check the false secrets told to different mole suspects and find that the mole is nearby.

The stationmaster said to Yu Zecheng, Look, there are only two of us left in our station now. Do you think I look like Mount Emei?

This is a very difficult and arduous task. How to find it,

Please watch a TV series "Yan 'an Eliminate Rape".

It describes how to investigate and eliminate rape.

First of all, we should use logic to establish the object of investigation; Then we must collect evidence in secret, and we must not startle them; Finally, the mole is usually trapped and exposed in public, then the charges against him are announced and he is arrested.

Exclusion is the most commonly used method.
