German spies pretended to be working groups to inspect the Soviet command and knocked on the table a few times until they were still confused
During World War II, the headquarters of a former Soviet army was informed that the superior would send a working group to inspect and guide the work. The commander attached great importance to it and immediately made the deployment.
One morning, a group of officer-like men came to the headquarters, and judging by their mannerisms and the letters of introduction they carried, they were undoubtedly working groups sent by their superiors. They were warmly received by the Commander and reported in detail to the Working Group on all aspects of the Force and the recent organization of work. When he spoke of a recently drawn up battle plan, a yellow-bearded officer in the working group showed great interest and wanted to see it. The commander didn't say a word and asked the operational staff officer to take out the plan.
The yellow-bearded officer carefully read through the plan and asked some questions from time to time, and the commanders answered them one by one. After reading the plan, the yellow-bearded officer touched his beard, looked up, and said excitedly: "Well, very good, I am satisfied!" After saying that, I inadvertently tapped the table with my hand a few times. Unexpectedly, the sound of this "tuk tuk" tapping attracted the attention of the combat staff officer just now. He heard that this was the drum beat of the German March of Victory, and he thought: a senior officer of the Soviet Army can never inadvertently and never beat the drum beat of the German march, there must be an article in it!
So he took an opportunity to report the doubts in his mind to the commander. The commander was immediately alert, and he quickly got in touch with the superiors, only to learn that the working group sent by the superiors would not arrive until the afternoon. He then ordered that the members of the fake working group be detained. After interrogation, these people pretending to be "working groups" turned out to be spies sent by the German army.
Hey, that yellow-bearded German spy was so confused that he couldn't figure out how the Soviet commander could see them. He didn't expect that it was because he inadvertently knocked on the table a few times and leaked the chance, which led to the disaster of killing.
