Speaking of this, Du Kaishan walked to the map of Tianjin city hanging in Tao Jingfei's headquarters, picked up his baton and clicked on the few concessions he said, "As for the British and French concessions, although they are far away from this bacteriological warfare force. However, the Japanese army already has a command headquarters here that is responsible for the entire Hexi battlefield, and if another corps-level headquarters is set up here. Then for a small theater of operations, the density of this high command is somewhat too high. ”

At the same time, the British, French and American concessions are around the Wanguo Bridge, and the Tianjin Railway Station is on the other side. In addition to the Japanese concession, it is also the location of the main wharf of Tianjin River Port. There are too many key targets within the range, and even if a fool knows these areas, they must be within the key targets of our army. Obviously, such an area is not suitable for the seat of the High Command. ”

"As for the Hedong Russian Concession, it is along the railway line and around the Tianjin Railway Station, which is also not suitable. The Italian Concession is also here, and it is easy to focus on too many targets, and it is also very disadvantageous to be between the Chinese Concession and the Russian Concession, which has a large number of strategic targets. As for the room for maneuver that is too small than the concession, once it is surrounded, there will be no way back. ”

"Judging from the entire process of the Tianjin Campaign you recounted, the commander of the 48th Division, Yongyi Tsuchihashi, is very cunning. Not only was he able to retreat almost completely under the siege of Wang Xiaoming's heavy troops. In the battle for your periphery, the main strength of the 48th Division was preserved. ”

"In the battle for the urban area of Tianjin, the artillery positions were also set up quite cleverly. Let us have the advantage of firepower, but we cannot use it. Moreover, the strict blockade of the Tianjin urban area has made it basically impossible for us to obtain effective intelligence sources for our offensive attack on the Tianjin urban area. This shows that this person is quite cunning, and he is definitely not the kind of general who is hard-hitting. ”

"Judging from these characteristics, this person will definitely not set his headquarters in such an obvious place, waiting for us to end. Capture the thief and capture the king first, this is the characteristic of our Eastern War, and he will not be unclear about this. Especially when the Kwantung Army has suffered a lot of losses on us many times, he will not fail to learn a lesson and set up his headquarters as concealed as possible to reduce the possibility of being raided. ”

Of course, before the collapse of the war situation in the Japanese Concession, it was not impossible for his headquarters to be set up in these areas. But one thing is clear to me, even in these areas. But after the collapse of the war situation in the Japanese concession, he will definitely transfer with the command headquarters. ”

Because if he can't see the battle for Tianjin City anymore, he is already powerless, it will not be in line with his performance since the war. So I think even his original command is in the places I mentioned earlier. But after the tide of the war in the Japanese concession was reversed, he would definitely transfer his command at the first time. ”

He broke with the Japanese army's convention of reducing the level of command as much as possible on a single battlefield. On the east and west banks of the Haihe River, a headquarters was set up for each. It shows that he is not the kind of person who is old-fashioned and only knows mechanical dogma. If I am not wrong about his whereabouts, it means that he must have the possibility of the battle situation deteriorating at any time, and prepare an emergency plan. ”

"So even if his headquarters is being transferred, it will not cause confusion in command. Judging from the technical support capabilities of the Japanese army and the distance between the battlefields in Tianjin, even in the process of transferring his command, it may not really interrupt the command. Judging from the previous battle situation, this guy is very ghostly, and he won't fail to understand the truth of the three holes of the cunning rabbit. ”

"At the same time, you said that from the beginning of the battle for the city, all the high-power radio stations in the city disappeared and were replaced by a large number of fifteen-watt radios. This is normal, the fifteen-watt radio can be contacted directly with Jinan, and even with the Kwantung Army. Under the current war situation, the base camp of the Japanese army could not help much, and it was enough to contact Jinan and the Kwantung Army. ”

"If there is a fifteen-watt radio station that can meet the needs, why keep a high-power radio station so that your opponents can easily find their location? In addition, the fifteen-watt radio is also a field radio, so it does not need to rely on a fixed power supply. Whether it's a hand-cranked motor or a small gasoline generator, the power supply needs can be easily met. ”

"In such a narrow battlefield environment, no matter what position our headquarters is in, it has been exposed to our guns. It is normal for the Japanese army to stop using high-power radios to cover up the location of their headquarters, and we would actually do the same. ”

"But old comrade-in-arms, have you ever thought that it is very likely that this Lieutenant General Tsuchihashi Yuyi, during the entire battle, not only did not use a high-power radio, but even a fifteen-watt radio station was not used? Those fifteen-watt radio stations in the city, in addition to confusing us, there is another possibility. It was used as a relay station to relay the radio station between the regimental headquarters of the 48th Division and Jinan. ”

"And the five-watt radio station in their division and regiment headquarters is only responsible for receiving and distributing? In this way, it does not affect the safety and ensures the smooth flow of communication. Lao Tao, on the Haihe Plain, the power of the five-watt radio station is enough to cover the entire urban area of Tianjin, and the most important thing is that it is not noticeable. As for the antennas that do not require special settings, there are ways to camouflage. ”

"I think your whole goal is wrong. This way, you don't change tactics in search of the areas where you change tactics and take the mercury offensive. And place your search area within the boundaries of Tianjin Huajie. Also, don't just search Hexi, the Hedong area, mainly the original Austrian Concession area, should also search. The point is to have a basement, or a place with complete underground fortifications. ”

"There's another place where you're sending someone to search carefully. That is the area south of Yoshino Street in the Japanese Concession, and it is mainly an area that has not been through major battles before. This also includes the location of your headquarters, the entire Haiguang Temple, the Japanese crematorium and the triangle of the French Concession. ”

"There is a saying called dark under the lamp, and you can understand the specific truth of this sentence without me saying it. Many times, in this kind of street fighting, the more dangerous the place, the safest place. Maybe the little devil, the headquarters of the 48th Division, is hidden under your nose. ”

"But if you want to catch this guy faster, I have another way you might try. That is, all your radio stations, including all the radio stations in Tianjin, as long as they are in our hands, all adopt radio silence. ”

"At present, the battle of Tianjin has ended, and the defending enemy of Tianjin has been completely annihilated by us. At the same time, our army had captured Tanggu and completely solved the last Japanese stronghold around Tianjin. In this case, even if this earth bridge Yongyi is calm and steady, he has to try to escape. ”

"But in the case that the surrounding area is already occupied by us, unless he has the courage to jump into the Haihe River and swim all the way out of Dagu under our noses in this weather. And safely cross the frozen area of the entire Bohai Bay before boarding the boat. Otherwise, if he wants to get out, he can only find another way to leave the city of Tianjin first. ”

"That is to say, they either risk being captured by us at any time and take the overland route from Tianjin directly to Jinan. Or he fled outside Tianjin, waiting for his superiors to send a plane to meet him. By land, it's certainly not safe. The Jinpu railway is now completely interrupted, and there are not only our troops along the line, but also a large number of brother troops on both sides of the Jinpu road. ”

"Plus the language aspect, and the issue of carrying weapons. He wanted to walk to Jinan or Texas, which was too risky. I don't think the possibility of them choosing this way of escape is not at all. But unless there is no third way to go, it is unlikely to be. ”

"So if he wants to escape, there are only two ways. Either escape from the city and find a flat place where you can take off and land small planes. Either they are fleeing out of the city and running to the beach to wait for the Japanese to send ships with ice-breaking capabilities to meet them. However, the second option requires too many resources and is not very likely. ”

"The only thing that is most likely is that he and his superiors communicated by radio. Taking advantage of the detailed map in hand, as well as the fact that the terrain south of the urban area of Tianjin is flat and large, it is impossible for our army to be tightly deployed in all areas. Find a way to escape from Tianjin City first, and then contact the plane to pick you up. ”

However, no matter what method he chooses, as long as he wants to escape safely back to the Japanese-occupied area, he must contact his superiors. I'm afraid that a five-watt radio station is not enough, at least he has to use a fifteen-watt radio. As long as we ourselves keep the radio silent, reduce the interference of the air signal and pay attention to the monitoring, it is not very difficult to find his approximate location. Once you've found the approximate location, it's better to search for it than to look for a needle in a haystack. ”

After listening to Du Kaishan's idea, Tao Jingfei frowned: "This is a good way for you." But there's one thing I can't figure out. You said that the area east of Yoshino Street in the Japanese Concession, isn't that right under the nose of my headquarters? Is this so possible? ”

Tao Jingfei's words fell, but Du Kaishan shook his head with a wry smile: "Old comrade-in-arms, since the July 7 Incident, the Japanese army has occupied Tianjin for seven years. Seven years is not a long time, but it is not a short time. During these seven years, was it difficult for the Japanese army to try to make something underground in Tianjin? ”

"It has been 46 years since the Japanese Concession was opened at the end of the last century. With the virtue of the Japanese, it is simply impossible not to do anything in the Japanese concession. In addition, it turned out that Tianjin was the place where Japan garrisoned the most troops in China before the July 7 Incident. ”

"Haiguang Temple, in particular, has always been the location of the headquarters of the Japanese Chinese garrison. Around here, after all these years, you won't think that the Japanese army has not done anything at all. Even if it's not on the ground, what about the underground? More than 40 years is enough time for the Japanese to make some tricks on this land. ”

"The reason why I say that this Tsuchihashi Yongyi will not choose the British, French, American, and Italian concessions as the location of his secret headquarters is because these concessions are basically under their full control after the outbreak of the Pacific War. The Italian Concession was finally taken under Italian control after its surrender last year. ”

"Before occupying the concession, they did not trust Westerners, including their allies, the Italians. Moreover, the British, French, and American concession authorities will not allow them to engage in these things in their own jurisdictions. After the outbreak of the Pacific War, the time was too short, and they would not have much opportunity to build on a large scale. Therefore, the focus of your investigation should still be within the Chinese boundary and the area south of the location of the Japanese Concession where its bacteriological warfare troops were found. ”

Du Kaishan's words fell, but Tao Jingfei fell into deep contemplation. Du Kaishan's analysis made Tao Jingfei suddenly feel a sense of empowerment. Without any hesitation, he immediately grabbed the phone and called a regiment. Starting from the area around Haiguang Temple's own headquarters, he dug three feet deep into the Japanese concession step by step.
