After Guo Bingxun quickly recorded Yang Zhen's order, he immediately began to transfer troops to the battlefield in northern Jin. According to Yang Zhen's request, the headquarters of the 10th Division was given priority to be airlifted to northern Shanxi. The rest of the troops newly integrated into the 10th Division began to be airlifted from the 13th Engineering Regiment, which is the most fully formed, and the two battalions of the Headquarters Guard Regiment.

Other troops were rapidly concentrated in Harbin and Qiqihar. To the two battalions, two battalions were airlifted to the north of Jin. Taking into account the overall situation of the battlefield in northern Shanxi, all the 10th divisions were transferred to northern Shanxi by air. Dispersed transportation, after arriving in northern Shanxi, centralized training is carried out.

The two railway corps that were withdrawn from the construction site of the Tongliao-Kailu railway immediately boarded the nearest train and were directly transported to Harbin for training and replacement of weapons and equipment. The reason why the railway soldiers were not used nearby was because these railway soldiers needed to be trained for a long time. Although the regiments to which these two railway columns belonged were the closest to Tongliao, they were not combat units after all.

Just when Guo Bingxun was racing against time to reinforce the northern Shanxi battlefield and mobilize reinforcements with all his might, the entire Shanxi battlefield had started on all fronts at this moment. After intense deployment, the main force of the Jinsui Military Region to the south launched a siege on all sides against the Zuojian detachment hidden in the mountainous area north of the Jingle and Lanxian roads, and when the target had already been determined.

However, the left detachment could not hold on to it under the cover of mountainous terrain and artillery fire. And relying on the abundant grain and ammunition stored before the war, as well as the continuous tactical counterattack of Tongguò, he repeatedly fought with the main force of the Jinsui Military Region participating in the war. It was precisely in response to Chen Hanzhang's initial worries that this battle was fought from the beginning.

The repeated tug-of-war dragged the hands and feet of the troops of the Jinsui Military Region. On the second day of the battle, in a ravine in the Japanese-controlled area, the troops of the Jinsui Military Region who participated in the battle found the remains of thousands of Chinese massacred by the Japanese army. Obviously, this is the pre-war plundered civilians who were massacred by the Japanese army after the fortifications were built for the Japanese army.

And in the northeast of Jin, Du Kaishan, who had already rushed to the battlefield in the north of Jin, took over the command of the entire battlefield in the northeast of Jin. Without the slightest delay, he turned most of his troops to the west. Focus on the county town of Guangling, as well as the surrounding Japanese army to carry out an offensive. With the strength of one regiment, with the cooperation of a battalion of the first subdivision of the Shanxi-Chahar-Hebei Military Region, they seized Feihukou and cut off the connection between Wei County and Laiyuan.

His main force cut off the highway between Guangling and Weixian, and between Guangling and Lingqiu. With the troops who launched a diversionary attack head-on, they completed the encirclement of the Japanese troops in Guangling and Lingqiu. And one of them launched an attack in the direction of Pingxingguan with a bluff. Although it had not yet torn apart the inverted triangle formation of the Japanese army in the northeast of Jin, it had encircled one of its arms.

At the same time when the northeast of Jin Province was fighting into a pot of porridge, the 21st Division of the Japanese Army suddenly entered Dai County out of Wutai Mountain, and concentrated its forces to launch a fierce attack on the line from Yanmen Pass to Guangwu. After an encounter with Su Yingqi, the speed of the 21st Division's actions increased significantly. On the second day of the encounter with Su Yingqi, his vanguard troops were stationed in Dai County.

In fact, the 21st Division encountered by Su Yingqi was only a part of its break. As early as the day of Su Yingqi's departure, the main force had already entered the Wutai Mountains between Lao County and Dai County. If you really want to encounter the main force of the 21st Division, I'm afraid it won't be so easy for Su Yingqi to get out in the first place.

On the day when the 21st Division launched an attack on the front line of Yanmen Pass, the 32nd Division in Taiyuan did not participate in the northwest of Shanxi Province nor participated in the sweep of the Taihang Military Region. Instead, they concentrated all their troops, took trucks through Dingxiang and Wutai, and quickly went straight to the north bank of the Hutuo River.

Its vanguard troops, without waiting for the follow-up main force to arrive, immediately launched an attack on the Ruyuekou line after arriving at Fanzhi. And preemptively seized the two commanding heights in the Ruyue Pass, Tiejialing and Wudou Mountain. The artillery was erected on the ironclad ridge and constantly carried out artillery strikes in depth.

At this time, the entire Shanxi battlefield, from the southeast of Jin to the northeast of Jin, was full of dense gunfire. The war and wolf smoke covered almost the entire land of Shanxi except for the southwest of Shanxi. The invading Japanese army mobilized almost all the forces that could be mobilized in North China and launched a full-front counterattack to northern Shanxi and southern Chanan.

Facing the 32nd Division of the Japanese Army, the direction of action was almost unexpected by everyone. Chen Hanzhang did not panic, but transferred two battalions from the battlefield in northeast Jin, and transferred the 13th Brigade of the 6th Column of Jinsui left by the boss to this direction. Taking advantage of the terrain, the tactics of resisting step by step were adopted to delay the actions of the 32nd Division.

However, the commanding heights of Ruyuekou Pass, Tiejialing and Wudou Mountain, were lost and occupied by the Japanese army before the arrival of the blocking troops, but Chen Hanzhang was somewhat caught off guard. Tiejialing is located in the Ruyue Pass, with an altitude of more than 2,000 meters, and is the commanding height inside and outside the entire Ruyue Pass.

Once the Japanese army occupies this place, it will be unobstructed within a radius of dozens of kilometers inside and outside the Ruyue Pass. Its artillery fire can completely suppress the mountains on both sides of Ruyue Pass at an altitude of only more than 1,000 meters. The Japanese army of Tiejialing and Wudoushan won first, and the blocking troops could only retreat to the north of Ruyuekou to block the attack.

In this way, it was too close to the ambush circle he left for the 21st Division. Once this 32nd Division went west, not only would its entire tactical intentions be exposed. At the same time, the back of the encirclement force will also be fully exposed. At that time, not only would he not be able to complete the encirclement and annihilation of the 21st Division, but he would be faced with the situation of being attacked by the enemy on his back.

Moreover, after the loss of Tiejialing, all the troop movements outside the Ruyue Pass were almost impossible for the Japanese army to protect. The artillery fire deployed on the ironclad ridge also poses a powerful threat to the movement of troops in depth. However, in the counterattack against Tiejialing, under the situation that the follow-up troops of the 32nd Division had arrived one after another, Chen Hanzhang had no hope of recapturing it by relying on the blocking troops unless he mobilized a large number of troops.

Faced with the 21st Division getting closer and closer, it is too late to adjust the deployment. Chen Hanzhang gritted his teeth, determined to respond to all changes with the same. For the time being, no adjustments will be made in the deployment, and the main operational target will still be the 21 st Division. First hit this main division of the Japanese army, which had never suffered any blow since it was put into the Shanxi battlefield.

The original blocking force on the front line of Ruyue Pass was ordered to immediately cooperate with a regiment in the Beiyue District, which had been deployed here. Take advantage of the mountains on both sides of Ruyue Pass to resist at any cost, and buy at least three days for the battlefield on the central front. Even if all the troops are exhausted, they will have to hold out for three days.

Taking into account the strength of the 32nd Division in the direction of Ruyuekou, there were roughly two and a half wings. At the insistence of the boss, Chen Hanzhang quickly transported the only 14th Brigade of the Jinsui Sixth Column to Yingxian County by car. Along the first line from Ruyue Pass to Yingxian, it was immediately put into defensive operations as a second-line unit.

In the middle of the road, the regiment in Beiyue District that had been holding the front line of Yanmen Pass was used to adopt the tactics of resisting step by step, leading the 21st Division to the direction of Guangwu. However, to the great surprise of Chen Hanzhang and all the troops participating in the battle, the 21st Division of the Japanese Army suddenly stopped attacking on all fronts after occupying Yanmen Pass.

The whole division and regiment began to build fortifications in a hurry, inside and outside the Yanmen Pass, and put on a posture of defending the Yanmen Pass according to the natural dangers. The 21st Division stopped the offensive and directly hung aside the ambush circle set up by Chen Hanzhang in Yanmen Pass.

At the same time, on the front line of Ruyuekou, the offensive of the 32nd Division became more and more fierce. Although the blocking force relied on the terrain to continuously delay the Japanese offensive, under the fierce fire of the Japanese artillery, the number of casualties was rising every hour. The Japanese army's tactics of attacking in the east and defending in the west made Chen Hanzhang immediately feel considerable pressure.

In order to alleviate the pressure on the first line of Ruyuekou, Chen Hanzhang took the risk of withdrawing all the alert troops on the first line of Loubeikou to the second line. Let open the gate of the north entrance of the building, and let this 32nd division divide the north entrance of the building. The north entrance of the building, which is located in the Hengshan Mountains, is close to Hunyuan County.

Once the Japanese army chose to divide its forces from the north entrance of Lou to attack, Chen Hanzhang could only give up the offensive against the Japanese army in Hunyuan County. At the same time, the 32nd Division will also be integrated with the Hunyuan Japanese army, which will be extremely unfavorable to the next battle. The entire battlefield in the northeast of Shanxi Province will also be turbulent on all fronts. But when he had no choice, Chen Hanzhang could only take this risk.

But no matter what method Chen Hanzhang adopted, the 32nd Division was like a tendon, staring at Ru Yuekou's line. Concentrate troops to attack the first line of Ru Yuekou, and it is not far from the straight line distance of Ru Yuekou, and the north entrance of the building, which has been opened at this moment, is as if it has not been seen.

And the 21st Division on the front line of Yanmen Pass on the central line is also like this. Yang Wankou, who was close at hand, as if there was no such thing, put the entire division on the line from Yanmen Pass to Yangmingbao. The hedgehogs of the two divisions gathered together and put on a complementary posture, which made Chen Hanzhang feel an abnormal headache.

Even if the troops were mobilized and the whole line went south to counterattack, the troops at hand were not enough to deal with the two divisions of the Japanese army at the same time. You attack the 21st Division in Yanmen Pass, and this 32nd Division can come to the rescue quickly. Once the attack is focused on the 32nd Division, the attacking force will be flanked from both sides by the 21st Division and the enemy in Hunyuan.

Although the Japanese army adopted a series of bewildering postures, Chen Hanzhang knew very well that the Japanese army, the 21st Division, did not really stay on the front line of Yanmen Pass. This posture is just to confuse himself. If he had transferred his troops to fight the 32nd Division first, the 21st Division would have unceremoniously driven straight in.

can clearly know the true intention of the Japanese army to adopt this tactic, but Chen Hanzhang, who has used his troops to the extreme, has nothing to do in the face of this situation. He didn't want to adopt a purely defensive posture, because in his opinion, it would be a force that made him very mobile and tied up in battle.

However, if the whole army now concentrates on setting up ambush troops and moves south, and encircles and annihilates this 21st Division on the left and right of Yanmen Pass, there will be two headaches. First, there were not enough troops to cover the flanks to deal with the inevitable rescue of the 32nd Division. Second, the complex terrain in Yanmen Pass also restricts the movement of its own tank troops.

Third, and most critically, there is a difficult problem that cannot be solved. Once they go south, there will be no more mobile forces on the entire battlefield. Once a new enemy situation arises, it is simply not possible to deal with it. Unless the protection of the flank of the main force of the Jinsui Military Region is abandoned, two regiments commanded by Mu Changqiu will be transferred to attack in the northeast direction across the Tongpu Railway. Otherwise, once the war is in a stalemate, it is easy to delay things.

Once Ying County gains and loses, the entire battlefield in northern Jin will be divided into two parts. If the 32nd Division attacked San'in to the west after capturing Yingxian, then its troops going south to Yanmen Pass would be surrounded by the Japanese army on the battlefield within Yanmen Pass.

With a Japanese division close behind him, no one could turn a blind eye. Especially at the moment, his own depth and emptiness have been used to the extreme, and there are almost no defensive forces. The troops of the 32nd Division were blocked and fought into such a refueling situation. It is destined that this battle will be solved on the inside line by itself, and it will not be able to pull to the outside line.
