According to the prediction of the Japanese North China Front, once the Anti-Japanese Union attacked Tianjin, the Japanese concession, which had important targets, would be the preferred attack range. There were too many exits left in this secret command post, and it was too late to expose itself. Therefore, after opening the passage at the bottom of the wall, the Japanese army immediately blocked the secret entrance and exit of the East Asia Tobacco Company.

After the Battle of Tianjin, Haiguang Temple became the target of the first wave of attacks of the Anti-Japanese Federation. In order to cover up the secrets in Haiguang Temple, the Japanese army destroyed the wall of the secret exit in Haiguang Temple with long-range artillery before evacuating the front line of Haiguang Temple. Create the illusion that it has been destroyed by the fire, so that the exit can be covered directly with a pile of rubble.

At the same time, when the anti-coalition forces had already reached Yamato Park and were close to controlling the entire Japanese concession. Lieutenant General Yuyoshi Tsuchihashi ordered his troops to blow up another exit in the Japanese concession. If it weren't for the fear that the river would enter the channel, he would drown himself. As well as exposing the location of this underground command post, I am afraid that Tsuchihashi Yongyi will explode directly from the passage under the wall river.

As early as when the Japanese army built this secret command post, a large number of explosives were planted under all the passages in order to prevent accidents. In order to blow up all the contents inside this command post, along with a large number of other secrets hidden inside, in case of unfavorable circumstances.

However, the overall scale of this secret underground command post is not large, but it is also a sparrow, although small, it is also full of organs. In addition to a complete ventilation system and water intake system, there is also a hidden electrical connection to the outside world. It also has its own gasoline generator, so it can maintain a sufficient power supply even if the circuit connecting with the outside world is cut off.

The stockpiled supplies such as food and ammunition can meet the needs of an infantry brigade for half a year. But due to the size of the group, it can only accommodate one infantry brigade at most, which is already the limit. Moreover, this underground secret command post is just a simple command post. Unlike the various fortresses of the Japanese army in the northeast, they only had defensive capabilities and no offensive capabilities.

At the same time, the confessions of these Japanese prisoners of war also confirmed another speculation of Du Kaishan at the beginning. During the entire Tianjin Campaign, Tuqiao Yongyi's own high-power radio stations could only receive and not transmit, and all reports to the temporary garrison of the Jinan Front Army were transmitted through two 15-watt radio stations set up in the Austrian Concession using the low-power tactical radio stations that followed him.

In order to avoid revealing his location, he placed several fifteen-watt radios in different locations throughout the city, and numbered them all for use as transit and backup stations. This effectively avoids the anti-United Nations surveillance department from locking down the location of his headquarters by radio.

Combat command over the entire urban area of Tianjin was also conducted through more than a dozen tactical radio stations at the brigade level in their hands. In Tsuchihashi Yongyi's view, since the enemy army has reached the urban area, for the battlefield commander, the communication distance of these tactical radio stations is sufficient.

His headquarters, whether it was in the First District Office or moved to this secret command post, did not have any wired communication equipment to the outside world. Even if the anti-coalition troops called his headquarters, it would be difficult to find the location of his headquarters through the telephone line.

After the Anti-Japanese Union launched a rapid artillery attack on the Japanese fleet on the Haihe River, it crushed the fleet on the Haihe River. Lieutenant General Yuyoshi Tsuchihashi, who was sitting at the headquarters, immediately sensed that something was wrong. Taking advantage of the short lull period of the stalemate in the attack on the Japanese concession by the Anti-Japanese Alliance, he moved to this secret command post set up southeast of Haiguang Temple through a secret passage set up in the residential area of Gong No. 40 and under the cover of the guard squadron.

In order to ensure the safety of his command post in the street fighting, Lieutenant General Yongyi Tsuchihashi can be said to have put a lot of effort into it. However, it did make his opponent Tao Jingfei, in order to find him, he worked hard, so he almost didn't dig three feet into the ground. And in the entire Tianjin battle, even at the last moment of the Tianjin battlefield, his command was never interrupted.

It was this guy's cunning that allowed him to escape countless searches and arrests by the anti-coalition forces. If it weren't for Du Kaishan, who also likes to take the edge of the sword, he would have passed through Tianjin to see his old comrades-in-arms. In addition, this guy did not want to use a high-power radio station, and tried to contact Jinan with only a five-watt radio station, but he was never successful, and he has not yet been able to decide the way to evacuate.

And because Tao Jingfei's headquarters is set up in Haiguang Temple, the security around this is too strict. I never gave this guy a chance to slip out, maybe he really let this guy slip out. Because this secret command post is the last exit of Henan in the wall, it is close to the suburbs of Tianjin. When you cross a road, you have a lot to offer.

Through the confessions obtained from the interrogation of these guys, Tao Jingfei not only figured out the mystery of the disappearance of the Japanese military headquarters in Tianjin, but also found that he had caught a lot of big fish in this underground command post. Except for those killed or captured on the battlefield, almost all the top leaders of the remaining Japanese army in Tianjin were in it.

Among the Japanese officers who were killed or captured during the purge operation. There were not only most of the officers of the regimental headquarters of the 48th Division, but also a large number of the headquarters of the North China Front. Even the Chinese dispatch army, and even the headquarters of the various organs in Tianjin.

When Okamura Ninji withdrew from Beiping to Tianjin, he split the North China Front Headquarters in two. He took part of Jinan and stayed in Tianjin to assist Lieutenant General Yongyi Tsuchihashi in defending Tianjin. Among the two major generals who were killed, one was Major General Nakanishi, the current deputy chief of staff of the North China Front, and the other was Major General Miyazaki Monday, an officer at the Japanese Army University.

In his capacity as head of the Fourth Division of the General Staff Headquarters, this old man was ordered by the base camp to accompany the wing that landed in Tianjin to the Pingjin battlefield to assess the battle situation. As a result, he didn't expect that he was trapped in Tianjin City and could not return to his homeland. Together with the wing that landed in Tanggu with him, the jade was shattered in the city of Tianjin.

It is a pity that this person was killed, and the intelligence officers who participated in the interrogation were very sorry. The fourth director of the Japanese Army General Staff Headquarters, this is a rare core figure in the Japanese army base camp. If you can catch it alive, you will definitely get a lot of good things out of his mouth.

It's just that the troops who went down to clear up the situation didn't know the true identity of this guy, and there was no way to show mercy to his subordinates. In addition, this guy and the major general Nakanishi Sadaki are also extremely fierce. In the face of the anti-United Nations anti-United Nations anti-Japanese troops, they actually hid in a secret room and pulled out their pistols to shoot at the anti-United Nations troops.

As a result, a grenade was used to solve two people together. When the two of them collectively went to the west and the troops saw that the two people were actually wearing the rank of major general, they regretted it too late. Compared with these two fierce guys, it was much easier to capture Tsuchihashi Yongyi.

As soon as the clearing troops went down, they encountered Yongyi Tsuchihashi, who was pacing back and forth in the passage with two guards, and was worried about the predicament. After killing the two guards behind him, the butt of a rifle smashed directly into the bundle before the guy took out his pistol and shot himself in the head.

There is no way, compared to the two recalcitrant major generals who hid in the secret room. This old man was illuminated by the lights in the passage, and the rank of lieutenant general on the collar badge was too obvious. So although the soldier's hand was a little heavier, the butt of the gun that made Tsuchihashi Yuyi suffer was very heavy, and he was almost smashed out of the concussion. He was unconscious for a long time, but after all, he was caught alive.

As for the captured Japanese Army Daisa, his true identity can be said to have made the intelligence department ecstatic. As the head of the Japanese secret service in Tianjin, although he is not as high as Tsuchihashi Yongyi in his position, because of his special status, the intelligence department pays more attention to it.

As long as this guy's mouth can be pried open, not only can he find out the Japanese army's spy operations in the whole of North China, but he can also find out a considerable number of Japanese spies hidden in North China. For the intelligence services, this guy is a super big baby.

The remaining officers above the rank of assistant are not only those of the 48th Division, but also the North China Front and other systems of the Japanese army, and there is also a lieutenant who is the captain of the Japanese military police in Tianjin. The army commanders who were killed, except for the chief of staff of the 48th Division, were all quite heavyweights.

Under this net, Tao Jingfei can be said to have gained a lot. However, after receiving Tao Jingfei's telegram, Yang Zhen, who had been attracted by the sudden change in the Shanxi battle situation at this moment, did not pay too much attention to it. For Yang Zhen, Tianjin has been completely recovered, and more than 30,000 defenders have all been annihilated.

Even if he runs away from Tsuchihashi Yiyong, it's not a big deal. The remnants of one elite division, two divisions, and two mixed brigades, as well as the military, police, and special organs of the Japanese army in Tianjin, have all been annihilated. That's the most important thing, and that's where the real impact comes in.

Compared with the victorious end of the Tianjin Campaign, the Eastern Hebei Theater has also completed the end. The Northeast battlefield is deadlocked, and there is no shortage of other fronts with two points. The current battle situation between Shanxi and eastern Henan makes Yang Zhen happy and worried. Especially the performance of the First Army on the Shanxi battlefield, Yang Zhen had a not very good premonition.

On the Shanxi battlefield, the Japanese army suddenly changed its original tactics of attacking the troops of the 18th Group Army, abandoning all the strongholds west of Yangquan on Zhengtai Road, as well as north of Taiyuan and west of Jinxi. Concentrate all the forces that can still be concentrated, ignore the all-out interception and encirclement of the surrounding Jin-Cha-Ji and Jin-Sui Military Region troops, and forcibly retreat to Taiyuan.

Concentrate forces to avoid the troops of the Taiyue and Shanxi-Hebei-Shandong-Henan Military Regions along the Nantongpu Railway and the Baijin Railway, divide all the troops into two routes, and quickly retreat to the south of Jin. As for those strongholds that had already been surrounded and the county towns, the defending enemies who were still stubbornly resisting, were directly abandoned by the First Army.

This time, when the First Army contracted the forces north of Taiyuan and along the Zhengtai Road, in order to achieve the maximum suddenness of the campaign, the movements were extremely hidden. All the fortifications and strongholds north of Taiyuan were not destroyed in any way. The equipment that could not be taken away was abandoned on the spot without any destruction.

According to the distance from Taiyuan, the troops retreating to the south alternately covered from far and near, and forcibly withdrew to Taiyuan as quickly as possible. The northernmost Japanese army was even ordered to hold on to the death in order to contain the troops of the 18th Army north of Taiyuan and create fighters for the rest of the friendly forces to evacuate safely.

With this hand, Lieutenant General Yoshimoto Sadachi, the brother troops, which mainly adopted the tactics of squeezing and cutting off the various units of the Japanese army in the Shanxi battlefield and annihilating the enemy in the movement, were somewhat caught off guard. Especially in the direction of Zhengtai Road, the troops of the Shanxi-Chahar-Hebei Military Region, which are focused on the line from Yangquan to Niangziguan, will not have time to act in the future.

Although most of the troops of the Jin-Cha-Ji and Jinsui Military Regions, which were fighting north of Taiyuan, discovered the Japanese army's moves, they continued to adopt the tactics of pursuit and interception, intercepting a considerable number of enemy troops and all the puppet troops. However, because some cadres hesitated and reacted too slowly, and because of the extremely rare Japanese army, they didn't care about the intercepted troops at all, and just buried their heads in the tactics of running wildly towards Taiyuan, and still let most of the Japanese troops run away.
