This Zuo Ma Jiu is a major general who is very cunning and extremely cautious in his actions. Although he had a direct order from the commander of the North China Front, he never lightly advanced the enemy, and his movements were always unusually slow, and his actions were always slow. As soon as there is any abnormality in the surrounding area, immediately occupy the nearest hill to organize defense.

Wang Minggui, who was responsible for the defense of the entire Tongpu Road West and Northern Jin Dynasty, focused on the Datong direction in the entire Northern Jin Dynasty battlefield. Moreover, this left detachment is extremely cunning, like a cunning fox, and always refuses to take a step lightly. Its location has been wandering, constantly wandering back and forth between Shenchi, Ningwu, and Shuoxian.

In addition to sending small forces to the north to constantly harass and loot food and supplies everywhere, the main force is unwilling to take a step north of the inner Great Wall. Nor did they carry out any division of troops, and the whole army shrank together. And there is no puppet army equipped with any kind, and it never stays in one place for two nights in a row. It is better to drag an army of thousands and travel through the mountains all day than to rest in one place.

Wang Minggui concentrated his forces several times, but he never caught the fighter plane and took down this left detachment. This left detachment is like a fangs stuck in the entire front line of the Anti-Japanese Federation, so that when you want to fight, you can't find anyone. If he doesn't pull it out, it is quite dangerous to let him wander between the two wings of the inner Great Wall.

This time, under the situation that the battle situation was about to change, Chen Hanzhang made a great determination to concentrate his superior forces and firepower first, and strive to pull out this poisonous fang before the Japanese army launched a large-scale attack. Stabilize the situation in the northwest of Luxi and Jin, and concentrate on dealing with Taiyuan and the emerging Japanese reinforcements.

At the same time, most of the troops were concentrated, and the focus of the defense was on the front of Hunyuan, Yingxian, and Guangling in the northeast of Shanxi. And concentrate a part of the troops, cross the inner Great Wall and preemptively attack the strategic points between Guangling and Lingqiu, Pingxingguan and Weicheling. The main force of the 69th Brigade was attracted from the source to the direction of Lingqiu, and the pressure on Du Kaishan was relieved before the advance.

Chen Hanzhang attacked the left detachment on the western front instead of defending first, and put the main forces on the deployment of the eastern front, which made Yang Zhen a little uneasy. What he was worried about was not the enemy forces that had now entered the northeastern part of Jin and the territory of southern Chanan. These are Japanese troops on the surface, and there is nothing to worry about.

The Japanese army that has been deployed does not have a big impact on the battlefield in northern Jin. As long as Du Kaishan completes the southward movement, the junction between the battlefields of Chanan and Northern Jin will be completely blocked, although the troops invested are not much. But it completely sealed the last weakness between the entire battlefield from southern Cha to northern Jin.

Moreover, although the number of reinforcements that the Japanese army has invested now is large, it cannot change the situation of the war with these troops. He was more worried about the 21st Division, which had not yet been put into the first line, the 15th Division, which was being reorganized on the Shimen front, and even the 32nd Division, which was still in Taiyuan.

These three Japanese divisions and regiments that have not yet appeared on the battlefield are finally invested there, which is what worries Yang Zhen the most. Invested in northern Jin, Yang Zhen was not very worried. What he was most worried about was that two of the three Japanese divisions would be thrown into the sweep of several major enemy base areas in Shanxi by Okamura Ninji.

These nails are placed at the junction of Hebei and Shanxi provinces, as well as the surrounding area of Taiyuan, which is always a hidden danger. If it takes the opportunity to sweep the northwest regions of Taihang and Jin, or even encircle Wei to save Zhao and attack the Yellow River and attack the Shaanxi-Gansu-Ningbo border area, then it will have a negative impact on the current war situation.

Especially in this 21st Division, which has been changed to light equipment and is now fully equipped. Appearing on the battlefield in northern Jin at a time when the two armies were at a stalemate is another dangerous factor. At present, although the Japanese army in the northern Jinbei battlefield has invested two brigade-level detachments and a division-sized detachment, these troops Okamura Ningji should know very well that they will not be able to recover the northern Jinbei battlefield at all.

They arrived a little too late. If the arrival time of these Japanese troops was three to five days earlier, if Yang Jicai had not raided Taiyuan, the time for the 32nd Division to arrive at the battlefield in northern Shanxi would have been forced back by several days. The battlefield in the north of Jin will definitely not be what it is now.

I am afraid that the Japanese army in Inner Datong will still be stubbornly resisting at that time, and the Japanese army from outside will have a large number of reinforcements, even if Chen Hanzhang gets the two divisions brought by Wang Minggui, and the strength of one division and one brigade drawn from the advance army. But at that time, I am afraid that I will also have to bear great internal and external pressure.

But now Datong has been taken, although this thousand-year-old city has been reduced to ruins, but now Jinbei has been firmly controlled in his hands. And after the enemy in Suiyuan has been completely eliminated and the remnants of the enemy in Chaxi no longer pose a threat, the entire supply line from the north of Jin to the northeast has actually been opened.

Although the route is somewhat long, and there is a lack of railways to rely on. But after all, the supply line has been completely opened. In addition, a large number of combat aircraft were deployed to the vicinity of the battlefield in northern Shanxi Province to provide reliable air support. It is difficult to have a decisive influence on this part of the Japanese army, which has advanced to the northeast of Jin.

Moreover, with the southward movement of Du Kaishan's entire army, the entire battlefield of southern Chanan and northern Jin has actually been connected. At present, the Japanese army wants to counterattack northern Jin, relying on the troops invested now, if these three divisions do not join the battlefield, there is no way to save the situation. This situation, Okamura Ninji should not be able to see.

If the enemy in the northeast of Jin Province attacks first, and the follow-up troops will participate in the battle one after another, this has formed the most unfavorable refueling tactic for themselves. With the strategic literacy that Okamura Ninji had shown before, as well as the ability of the senior generals and staff officers of the Japanese army, he would not fail to see the danger of the entire deployment.

But what kind of tricks is this Okamura Ninji doing? Although the information transferred by the central authorities is not very comprehensive, the focus is still very clear. Yang Zhen always felt that these Japanese troops who were placed on the second line by Okamura Ningji would not just sit back and watch the fierce battle in northern Jin and even the lack of troops to change the unfavorable situation, but bask in the sun on the Pinghan line and around Taiyuan City.

It is precisely because there are still three divisions, especially the fully equipped 21st Division, which has not yet determined the direction of its final investment, that Yang Zhen is a little worried about Chen Hanzhang's deployment. This is a fully equipped division, not a half-crippled division like the 15th Division, which has lost most of its troops.

And judging from the previous left-hand action, its action is extremely cunning. Its true combat intentions have not yet been clarified. If Chen Hanzhang attacked Luxi's left detachment first, once the battle dragged on, it would have an adverse impact on the entire battle situation.

If Okamura Ninji uses this left detachment to make stuffing, it will attract the attention of the surrounding anti-union. In addition to the troops in Ludong, the anti-coalition forces had no time to take care of the 32nd Division and the 41st Division around Taiyuan to launch an attack on the Jinsui Military Region. Coupled with the 21st Division, which is very likely to sweep away Taihang, these two wings are dangerous.

Moreover, Yang Zhen had a faint feeling in his heart that under the development trend of the entire Suiyuan and Northern Jin battlefields. Is the main force of this left detachment really opposite Wang Minggui? Judging from the current situation, this is not very likely. Okamura Ningji would not have placed such a lone army in the Guanshui Mountain in the northwest of Jin Province at this time.

Regarding Yang Zhen's worries, Guo Bingxun was a little disagreeable. Although there are so many more Japanese troops in the entire war situation in North China, the northern Jin Dynasty is now in full hands. Relying on the mountainous areas of northern Shanxi, coupled with the current equipment of the Anti-Japanese Federation, there should not be any big problems under the current situation that the entire front of northern Shanxi and southern Chanan has been completely connected.

The only problem is that after the 48th Division arrives at the front line of Zhangjiakou, the price to be paid for the battle for Zhangjiakou will be much greater. Guo Bingxun's opinion is still in accordance with Chen Hanzhang's method. Concentrate superior forces and firepower, and hit this left detachment first. It is still a wise choice to remove this fang, which is stuck in the front line, first.

However, Guo Bingxun somewhat disagreed with Chen Hanzhang's concentration of armored troops to deal with this left detachment. The area of all operations of the left detachment was in the mountains. Chen Hanzhang mobilized so many armored troops, but instead limited his actions to the road, which would undoubtedly leave a large number of loopholes in the entire deployment.

Regarding Guo Bingxun's thoughts, Yang Zhen shook his head and said: "I'm not criticizing Chen Hanzhang, this left detachment is only a few thousand troops, even if you look at them with a force, it won't have much impact on the battle situation." If it were me, I would have focused my main attention on this sixty-ninth brigade in Ludong first. ”

"The location of the 69th Brigade is the junction of the Japanese army's deep defense line, and it is also the starting point for its attack on our army's defense line in northeast Shanxi. If the 69th Brigade is defeated first, Zhangjiakou, which is an important town and provincial capital in southern Chanan, and the northern barrier of the Pingjin area, will be completely surrounded by our army strategically. ”

"Zhangjiakou is the gateway to the Pingjin region and an important town outside the Saiwai. If the Pingsui Railway along Zhangjiakou and the line were in the hands of the Japanese army, even if our army controlled the southern part of Chahar and the northwest of Hebei, it would probably be difficult for our army to gain a foothold. Unless our army is here, invest a lot of troops to hold on. ”

"But if Zhangjiakou is in the hands of our army, the entire Chanan to the Pingjin line will be shaken on the whole line. If our army is willing, it can go straight to Pingjin. Once the Pingjin area is shaken, the Japanese rule in North China will also be shaken on all fronts. This result will not be lost to Okamura Ninji's ability. ”

"At the same time, if this 69th Brigade is defeated by our army, it will be equivalent to the door of Hebei being completely opened by our army. No matter how barrier-free our army is, once the troops go out of the Maguan, it will be close to the Great Plain of Jizhong. At that time, our army's army in northern Jin and southern Chanan will be pressed. The battlefield will completely shift from the inner line of our army to the inner line of the Japanese army. This will be a fatal blow to the Japanese army's strategy of fighting and supporting the war. Therefore, no matter how many troops this 69th Brigade is, the position it is in now is a place where the Japanese army must be saved. ”

"If Chen Hanzhang concentrates his forces to fight this 69th Brigade first, the Japanese army will inevitably come to the rescue. By encircling Wei and rescuing Zhao, the entire Japanese army can be deployed on the second line, and the enemy army, whose current situation is still unclear, can be mobilized as soon as possible. At least mobilize the enemy of Taiyuan first. ”

"Then in a wide range of interspersed and roundabout battles in Tongguò, the entire situation in the northeast of Shanxi Province was completely disrupted. No matter what Okamura Ninji's thoughts were, it completely disrupted them from the roots. Let Okamura Ningji put on such a posture, that is, whatever the plan, he can only put it down first. You have to hit seven inches to fight a snake, what does it mean for you to pick five inches to fight? ”

"I don't object to persimmon picking a soft pinch first, but it is also time-split, fractal shì, although he also launched some tactical attacks on the Eastern Front, but the troops invested are a little too small, and it is not enough to completely muddy this pool of water, and it is difficult for Okamura Ninji to feel a real threat."

"These tactical counterattacks launched by Chen Hanzhang in the northeast of Jin Province are more in response to Du Kaishan's headquarters that are moving south from the front line of Huade and Shangdu, and finally fill a weak underbelly of our army in the battlefields of southern and northern Jin. The real intention is not to focus on this line. I can't say that Chen Hanzhang's deployment is wrong. But Chen Hanzhang first decided to fight this left detachment, and I think it was really inappropriate. ”
