Yang Zhen believed that when necessary, as long as the Japanese troops on the front line of Huade and Shangdu could withdraw, they could accept the loss of Suinan. But if it is said that Datong in the north of Jin is lost, it is unacceptable to the Japanese army no matter what. Even if the Japanese army gave up Suinan, it would definitely not sit idly by and watch the Anti-Japanese Union enter Shanxi.

Chen Hanzhang's hand can be said to have really stabbed the hornet's nest of the entire Japanese army in North China, which is bound to cause a chain reaction. Although Chen Hanzhang was a little prelude, Yang Zhen was not annoyed. In his opinion, Chen Hanzhang understood the essence of what is called the great in-depth operation of armored troops.

Although Yang Zhen was divided into three ways for Chen Hanzhang's soldiers before, he was indeed a little dissatisfied. Yang Zhen believed that in the face of the small number of Japanese troops in the entire Suinan, Chen Hanzhang divided the troops in his hands into three routes, which was a little too scattered among his strength. The focus of the entire Suinan operation was on the two ends of Jining and Guisui, as long as these two ends were choked, the Japanese army at Zhuo Zishan was not a matter at all.

Chen Hanzhang's soldiers were divided into three ways, and they were a little too scattered in their strength. Either way, there is no way to deal with the unexpected. At the same time, if Yi Liangpin had more troops there, the results of his raid might be even greater. At least it won't be like now, the assault force is insufficient, and it can only be in a stalemate.

This kind of divergent action itself shows that Chen Hanzhang has some inadequacies in anticipation of the unexpected situations that may be encountered. Especially in the direction of Jining, which was the only way for the Japanese army in Shanxi to reinforce the Suidong and Chaxi battlefields, the new enemy situation that might appear was not expected to appear. Therefore, Yang Zhen was very dissatisfied with Chen Hanzhang's action of dividing the troops into three ways in Wulanhua, but considering the battle situation in Suinan and the deployment of Japanese troops, as well as the possible situation, Chen Hanzhang divided his troops and adopted the method of dividing his troops into two heavy ends and light in the middle. At least Chen Hanzhang's choice of focus is quite good. Although he was very dissatisfied, he was quite acceptable, so Yang Zhen didn't say anything.

This time, under the circumstance that Guisui had already been captured, Chen Hanzhang concentrated his troops on the eastern and central routes, and controlled the Jining-Fengzhen section of the Pingsui Railway on the Jining and Fengzhen lines. The plan of transferring troops from the Western Front to use the Japanese troops in the northwest of Shanxi Province to attack and penetrate directly into the Datong front really satisfied him.

Whether he can win Datong or not, Yang Zhen is not very worried. After the 69th Division entered Suinan to fight, only an independent mixed 3rd Brigade was left in the entire Datong. And part of the strength of this brigade was also divided in Suinan. There are also a considerable number of troops, which are stationed in Yanggao, Tianzhen, and Huairen, and there is only one infantry brigade left in Datong at this time.

As long as the roundabout troops commanded by Mu Changqiu were in place in time before the new enemy troops arrived, it would not be difficult to take Datong. Of course, the city walls around Datong are also a difficult hurdle for Mu Changqiu. But judging from the battle of Guisui, there is always a solution to the problem.

In this long-distance attack, the key problem is a quick word. That is to say, after entering Shanxi from the mouth of the killing tiger, there must not be any stops along the way. It is necessary to take Datong before the Japanese army south of Datong reacts, otherwise once the battle is a stalemate, the entire attacking force will be in an extremely dangerous situation.

However, in this long-distance attack, as long as you enter the front line of killing the tiger, Youyu and Zuoyun along the way are the base areas of the Jinsui Military Region. Although the county seats and main highways of the two counties are still under the control of the Japanese army, they are subject to the war situation in Suinan, and the total number of troops deployed is not much. The rest of the puppet armies such as the Xingya Emperor's Allied Army and the Shanxi Suppression Communist Army, Yang Zhen still doesn't look at it.

The entire vast countryside of Youyu and Zuoyun is firmly in the hands of the Jinsui Military Region. In last winter's sweep, although the Jinsui Military Region abandoned all the county seats, the loss of stored materials was also quite large. However, most of the vast countryside is still in the hands of the Jinsui Military Region.

At present, the number of Japanese troops in the counties in the northwest of Shanxi Province is insufficient, and Yang Zhen really didn't see the remaining Xingya Emperor's Allied Army, Shanxi's Communist Army, and miscellaneous puppet security teams, garrisons, and other miscellaneous armed forces. Without the support of a backer, these guys are not even a rabble.

Although these puppet troops armed with the equipment of the Jin Sui Army captured by the Japanese army, they were still well-equipped. A considerable part of it was a puppet army composed of a small number of surrendered troops of the former Jin Sui Army plus captured personnel, and the training was quite well-trained. But the morale of these puppet troops is very low, and a considerable part of them are only used as a means of earning a living. Compared with the puppet Manchu army, the actual combat effectiveness is negligible.

The roundabouts along the way can basically be said to be equivalent to the interspersed with the inner line. With the cooperation of the left-behind corps of the Jinsui Military Region, which is familiar with the terrain and enemy situation, Yang Zhen is not worried about any great difficulties along the way. As long as Mu Changqiu is more decisive in his actions, there should be no big problem.

The most critical issue was to face the follow-up chain reaction of the surrounding enemy forces, the Japanese First Army stationed in Shanxi, and the Japanese North China Front after the capture of Datong. Datong is an extremely important strategic location, and the Japanese army is bound to launch a counterattack to recapture Datong.

The most critical thing now is that the entire Jining, Datong, and Fengzhen frontline, with only the roundabout troops in Chen Hanzhang's hands, will definitely not be enough to deal with the situation. At the very least, relying on the two infantry regiments and one cavalry brigade in Mu Changqiu's hands alone, it was absolutely difficult to resist the all-out counterattack of almost the entire Japanese First Army. And solving the dilemma of the Jining battlefield is definitely not something that the two regiments in Yi Liangpin's hands can solve.

It is easy to say that the Jining battlefield has broken through on the front line of the white flag, and the 26th Division has been encircled. The troops of the Western Front are currently engaged in fierce battles with the 110th Division and the 9th Brigade of the Independent Mixed Regiment, which have been successively invested by the Japanese army. If the Western Front is given an additional division, they are fully capable of sending part of their troops to reinforce the Jining battlefield in a short period of time.

If Mu Changqiu can seize Datong, then Chen Hanzhang's department, who has arrived on the front line of Fengzhen, can completely pull out his hand and turn around from the southern front, go straight behind the Jining battlefield, and join the Jining battlefield. The key issue now is Mu Changqiu's side, how to increase their forces after capturing Datong.

After hesitating for a moment, Yang Zhen sent a telegram to the two veteran commanders of the advance army who were commanding the battle on the southern front, requesting that no less than one division of troops be transferred from the battlefield in southern Cha and forcibly advance to the line of Tianzhen and Yanggao from between Zhangbei and Shangyi. At the same time, it is hoped that at this moment, the political commissar of the advance army, who is also the commander of the Shanxi-Chahar-Hebei Military Region, will coordinate the remaining troops of the Shanxi-Chahar-Hebei Military Region to cooperate with the interspersed operations.

The two major base areas of Beiyue and Pingxi, which are subordinate to the Shanxi-Chahar-Hebei Military Region, are the closest base areas behind enemy lines to Datong in northern Shanxi, except for the Jinsui Military Region. If they can participate in the war, they can at least contain part of the speed of the Japanese puppet army south of the Pingsui Railway, east of the Tongpu Railway, and west of the Taihang Mountain to reinforce the Datong battlefield.

After receiving Yang Zhen's telegram, although the two veterans of the advance army were surprised by such a bold interspersed action of the Anti-Japanese Federation, they still met Yang Zhen's needs. A division was drawn from the anti-coalition forces assigned to his command, plus a cavalry brigade to form a detachment, and forcibly interspersed in the direction of Tianzhen and Yanggao.

The Beiyue District was ordered to draw out no less than three regiments of troops and immediately deploy them along the banks of the Sanggan River. These three main regiments are the only three main regiments in Beiyue District that have been completely formed after the sweep that lasted from summer to winter last year, and they dispersed their troops as much as possible to solve the problem of supply.

Since the brutal sweep carried out by the Japanese army last winter, the troops left behind in the major regions of the entire Shanxi-Chahar-Hebei Military Region have been unable to sustain their winter supplies. In addition to retaining part of the mobile combat force, most of the main forces of the troops could only be reluctantly divided into pieces and dispersed in order to solve the problem of shortage of materials and food for the winter.

The Japanese army's winter sweep, which lasted for two months, was different from the previous summer and autumn sweeps, which annihilated the main force of the Kannai army as much as possible. The actual operational objectives are clear. Aren't you strong in survivability, and don't you pay attention to some kind of so-called people's war, which you fight when you have the opportunity and withdraw if you don't have the opportunity?

I will no longer be foolish to find your main force for a decisive battle, I will destroy your reserves, and completely destroy your base area. Even if you escape my blow, because you have no food to eat and no winter clothes, you can only starve, sleep, and freeze to death in the deep mountains and old forests. Killing, burning, and robbing all of them brought severe losses to all base areas in North China.

In particular, the Beiyue area, which was mainly swept by the Japanese army in the Shanxi-Chahar-Hebei region, suffered heavy losses. After the end of the Japanese army's sweep, 80 percent of the grain in the whole area was stolen. All the winter supplies that had been stored were burned down, and almost not a single house in the whole district was intact. A large number of young and middle-aged people were taken away, and a considerable part of the population was forcibly relocated out of the mountains.

Under the brutal sweep, in order to preserve the living force. In order to solve the problem of food and clothing for the troops when a large number of materials were destroyed and the base area was destroyed by the Japanese army, Beiyue District could only disperse the troops as much as possible before the launch of the Anti-Union Campaign. Before the launch of this campaign, it began to concentrate one after another.

The three regiments drawn out by the political commissar are the three main regiments with the most complete structure that have been preserved by the great efforts of Beiyue District. Moreover, in addition to these three regiments in the Beiyue District this time, the rest of the troops were concentrated very slowly because they could not solve the problem of supply. The rest of the troops wanted to concentrate on the battle, and they had to wait until April.

It can be said that in addition to the troops drawn from Chanan, the Shanxi-Chahar-Hebei Military Region, which is also the commander of the political commissar. In order to respond to Chen Hanzhang's roundabout action, the three regiments were taken out, and all the housekeepers in Beiyue District were taken out. The Beiyue District, with the fact that most of the Pingxi base area has been lost, is now the main force of the entire Shanxi-Chahar-Hebei Military Region.

Taking out these three regiments is equivalent to basically transferring them to the Shanxi-Chahar-Hebei Military Region, which is now scattered guerrilla, and taking out all the most combat-effective units. You must know that most of the current units of the Shanxi-Chahar-Hebei Military Region have abolished the battalion-level structure and reduced all regiments to five infantry companies.

And even these small regiments usually operate in a company as a form and disperse their activities. In addition, the backwardness of the means of communication, the lack of radio stations, and the excessively wide area of scattered activities make it not easy to concentrate. These three reorganized regiments are already the only main regiments in the entire Shanxi-Chahar-Hebei Military Region. In order to support Chen Hanzhang's detour, the political commissar took out the last bit of capital of the Shanxi-Chahar-Hebei Military Region.

In the Jinsui, Taihang, and Taiyue directions, after receiving Yang Zhen's telegram, the remaining troops of the Jinsui Military Region also concentrated the main forces of the only five regiments, as well as the guerrillas of some counties and districts, and immediately entered the territory of Zuoyun and Youyu to control the highway from Guisui to Datong. and launched large-scale sabotage and harassment warfare against the Japanese strongholds along the route.

The main forces of the two major regions of Taihang and Taiyue also began to concentrate one after another, preparing for the Tongpu and Zhengtai railways. And mobilize all forces in the base area to prepare for the rescue of the anti-United Nations pilots. The troops of the Hebei-Shandong-Henan and Southern Hebei Military Regions are also heading north, preparing to enter Shanxi to support the troops in the Taihang and Taiyue districts who had lost Yan Zhan Ng in the counter-sweep.
