Despite the forced passage, these wooden bridges are not necessarily really unbearable. But Yang Jicai really didn't dare to take this risk, regardless of the fact that he forcibly passed through these small bridges that were only a few tens of meters long and numerous. The only way to do this was to go through the guò in sections, which made the speed far behind the original plan.

Even the last wave of covering troops, which set off after more than ten hours, did not need to consider the load-bearing capacity of the bridge because they were on the road, but there was not so much trouble. In terms of travel speed, he rushed to the front of them, and rushed to the first line of Shiling Pass, which they had arrived before. By the time the train convoy led by Yang Jicai arrived at Shiling Pass, Su Yingqi had been waiting for him here for nearly two hours.

If it weren't for Yang Jicai's dispatch of the reconnaissance troops in advance, he secretly controlled the various Japanese strongholds south of Tongpulu Xin County. At the same time, Chen Hanzhang sent cavalry and armored clusters to the south to meet the Yuanping line. Before the arrival of Japanese reinforcements, they seized Xinkou and Yuanping, ensuring the safety of the retreat route north of Yuanping.

On this way, the railway from Taiyuan to Datong is more than 300 kilometers, and it may be difficult for Yang Jicai, who has walked for two whole days, to withdraw safely. Because the train fleet retreating from Yang Jicai, less than three hours after passing through Guòxinkou and Yuanping, the Japanese reinforcements had already arrived here, completely blocking the Beitongpu Railway.

And with the cover of part of the Jinsui troops and the Jinchaji troops, when the convoy arrived at the front line of Shiling Pass, they had all disembarked and withdrawn to their respective base areas. The entire convoy had no covering troops except for a basic battalion of the Jinsui Military Region and the troops led by Su Yingqi.

Even if it was only three hours at night, he would not face a squadron, nor a wing of Japanese troops. Rather, a whole brigade and a brigade-sized detachment of the Japanese army, equipped with a large amount of artillery and gas bombs. With less than two battalions of troops at his disposal, there was very little ammunition left in the whole army. As well as the eleven remaining tanks, which have almost run out of shells, it is impossible to safely break out of the encirclement while still protecting so much equipment.

Just when Yang Jicai was delayed in retreating a lot because of the load-bearing of the bridge. Behind him, the Shanxi battlefield was already a sudden change in the wind and clouds at this time. Just when Yang Jicai was slowly retreating to Datong, a new wave of Japanese reinforcements was seizing the time to gallop towards Taiyuan and the entire Shanxi battlefield.

The reinforcements drawn from the China Dispatch Army in East China had already broken through the Niangzi Pass line and entered Shanxi on the day Yang Jicai evacuated Taiyuan. The mountain village detachment, which was the vanguard of the team, forcibly entered the front line of Xinxian and Yuanping through Wutai just three hours after Yang Jicaitong Guò.

At the same time, although the Japanese army was unable to build the Zhengtai Railway for a while, it had already opened the road from Jingcheng to Yangquan. We are seizing the time to mobilize food, ammunition, and supplies for the Shanxi battlefield. The Japanese troops stationed in Changzhi and Linfen were also transporting grain to Taiyuan along the Nantongpu Railway and the Baijin Railway.

If Yang Jicai retreated, even if he only delayed for a day, and waited until all the Japanese reinforcements and supplies arrived, he would really not be able to leave if he wanted to. Once the Japanese reinforcements arrived, they came up from all sides and cut off the North Tongpu Railway. Except for the annihilation of the entire army under the city of Taiyuan, he had almost no second way to choose.

At the same time as this mountain village detachment, the Japanese reinforcements appeared in the entire North China battlefield, as well as the division-sized Takeuchi detachment. After getting off in Handan, it passed through Wu'an, Shexian, Licheng and Liaoxian, and marched towards Yushe and Taigu. If it weren't for the fear of needless losses due to the congestion of the Zhengtai Highway and the bombing.

As well as Okamura Ninji to this Takeuchi detachment, there are other plans for its use. The route of this Wunei detachment was chosen to the southeast of Jin, which was relatively far away, and did not take the Zhengtai Highway. If this Wunei detachment had gone to Jingcheng, Yangquan, and Yangshou, it would have rushed to the Taiyuan front line long ago.

And at the same time that the main force of this Wunai detachment had rushed to Yushe. After landing in Tianjin, the 47th Division, one of the two divisions drawn from the Southeast Asian battlefield by the Japanese army's base camp, did not make any rest and was marching to Zhangjiakou through the Pingsui Railway.

Not only was the division fully equipped, but it also carried a wing of Taisho four-year 150-millimeter howitzers brought over from the Philippine battlefield. At the same time, the department also strengthened the 13 field artillery pieces captured from the Philippine battlefield and formed a field artillery brigade on a temporary basis.

The 69th Brigade, which landed at Tanggu in the early stage, reinforced two mountain artillery squadrons, one field artillery squadron, and four rapid-fire artillery squadrons drawn from the mainland, had already reached the line from Laiyuan to Lingqiu.

Okamura Ninji, who had received a large number of reinforcements, ignored the fact that the Datong War had basically ended at this moment. The actual situation that the main force of the 15th Division and the 3rd Independent Mixed Brigade stationed in Datong has been completely wiped out. And constantly and frequently deploy troops, looking for a breakthrough, trying to defeat the troops of the Anti-Japanese Union in northern Jinbei and the main force of the advance army in one fell swoop, so as to redeem the current defeat.

After the reinforcements of the Japanese army in East China rushed to the Shanxi battlefield first, Okamura Ninji did not seem to be in a hurry to immediately put the two divisions transferred from the Southeast Asian battlefield into front-line operations. In addition to the 47th Division, which was making every effort to reinforce the Zhangjiakou line, he left the 21st Division and stationed it on the front line of Shulu, Zhengding, and Shimen.

In addition, Okamura Ninji is mobilizing materials to replenish this division with a large number of mules and horses and other necessary transportation capacity for mountain warfare. And from the artillery directly under the front army, the last four mountain artillery squadrons were transferred to replace the field artillery of this division, which was not suitable for mountain warfare. The last 120-mm howitzer brigade directly under the Front was also equipped with the division.

At the same time, the remaining strength of several independent mixed brigades and regiments left by the Japanese army in Hebei is also being frequently mobilized. After retreating to Shimen with heavy losses in the bombing, the 15th Division was withdrawn to Qingfengdian for reorganization, and was also supplemented by a field replenishment team. Although it has not been completed, its strength has been restored.

In the face of new changes in the enemy situation in the battlefields of southern Chanan and Shanxi, Yang Zhen, who had returned to the headquarters of the Anti-Liaoning Resistance League at this time, was also constantly adjusting his deployment. Du Kaishan's headquarters, which had already taken Huade and Shangdu, and completely defeated the main force of the 110th Division, except for leaving a force to clean up the battlefield and completely solve the small remnants of the 110th Division trapped between Huade and Shangdu.

The main force immediately moved south to cross the Pingsui Railway and spread out on the entire line west of Zhangjiakou to cooperate with the operations of the advancing army. At the same time, after the troops drawn from the Rehe battlefield arrived at the battlefield in northern Shanxi, they were immediately deployed on the line from Hunyuan to Guangling in the northeast of Shanxi, forming an overall combat situation with Du Kaishan in the south.

But considering this operation, it was all mountain warfare. In addition to leaving an independent tank battalion, Yang Zhen cooperated with the battlefields of Huade and Shangdu to clear out the remnants of the enemy. The rest of the Matilda II tanks were all transferred back to the Northeast Theater. However, Yang Zhen mobilized two howitzer battalions that were more suitable for combat in the northern Shanxi and southwestern Chasa battlefields.

Yang Zhen knew very well that although the 32nd Division was now unable to go north for the time being due to supply problems. But as soon as the supply is completed, the main force of the division will immediately move north. In cooperation with the Japanese reinforcements that had already arrived in Shanxi, a large-scale offensive was launched against the area currently controlled by our army in northern Shanxi.

In the case that the force has been used to the limit, it is impossible to increase the number of troops to the north of Jin. Yang Zhen could only find ways to increase firepower for the battlefield in northern Jin. At the same time, taking advantage of the fact that after the capture of Datong, the main battles on the battlefield in northern Jin were concentrated on the western front, and a large amount of ammunition and oil were transferred to northern Jin in a hurry.

At the same time, he telegraphed Chen Hanzhang not to stick to various points when carrying out defense. It is necessary to make use of the relatively complex terrain between the inner and outer Great Wall as much as possible and adopt a posture of mobile defense. And use the deep mountainous terrain to turn the entire inner and outer Great Wall into a tomb for the Japanese army.

Considering that the Japanese army could use the troops in the northern Jin Dynasty to reinforce the troops, Yang Zhen did not tie Chen Hanzhang's hands and feet in command. In addition to telegraphing Chen Hanzhang to be flexible and mobile in combat. He also told Chen Hanzhang that he did not need to ask for instructions in advance before taking action. When necessary, it can be played on a temporary basis.

However, Yang Zhen also told Chen Hanzhang in the telegram that it is necessary to pay attention to cooperation and coordination with fraternal units and to properly handle the relationship with fraternal troops. In the use of fraternal troops, we must pay attention to their strengths. Don't use the standards of the Anti-Japanese Federation to demand the fraternal troops in Guannai.

After giving Chen Hanzhang the order, he took into account the equipment and adjustment of the 21st Division, as well as the position of the rest of the 15th Division. I always feel that Okamura Ningji's adjustment is not like Yang Zhen, who was completely aimed at the battlefield in northern Jin, and sent three urgent telegrams to the boss and deputy commander-in-chief.

In addition to informing the central government and the two of them of their doubts. It is also hoped that the troops of the Hebei-Shandong-Henan and Southern Hebei Military Regions, which have already advanced to the Taihang region, will not continue to move north, and will stay on the spot to cooperate with the troops left behind in the Taihang and Shanxi-Chahar-Hebei Military Regions to deal with the unexpected situation that is very likely to occur. Yang Zhen thinks that it is better to keep more attention and leave more points to retreat.

At the same time, Yang Zhen repeatedly reminded the boss and the commander of the Jinsui Military Region, who had already rushed to northern Shanxi, that they must pay attention to guarding against the Japanese army taking advantage of the current emptiness of the Jinsui Military Region to carry out a sweep of our Jinsui base area, so as to reduce the pressure on the supply lines behind the Japanese army when fighting in northern Shanxi. To avoid the recurrence of the situation that our army continued to ambush Japanese convoys behind enemy lines during the Battle of Xinkou, which caused a lot of difficulties in the supply of Japanese troops.

If Yang Zhenjian really can't do it, he will change the original plan of deploying the main force of the Jinsui Military Region on the left flank of the northern Shanxi battlefield. The main forces of the Jinsui Military Region, which are gradually returning, will all be withdrawn to the base areas in the northwest of Shanxi Province in order to ensure the security of the base areas in the northwest of Shanxi Province and the Shaanxi-Gansu-Ningbo border region.

At the same time, the Taihang, Taiyue, and Shanxi-Chahar-Hebei Military Regions must once again make preparations for counter-sweeping. If the form permits, the troops of the Jizhong Military Region, which are currently in the Taihang Military Region, can be returned to the Jizhong Plain to fight at an appropriate time under the command of the profit-making personnel. At this time, the Jizhong District, which had become the core area of the Japanese army, made a big disturbance in the Heavenly Palace, dispersed the Japanese army's forces, and reduced the pressure in the base area.

While adjusting the deployment on the ground, Yang Zhen transferred most of the Il-4 bombers and two-thirds of the A-20 attack planes that still had the ability to fly to northern Shaanxi and several airfields in Guisui and Jining to make up for the dilemma of insufficient ground troops and firepower. And one-third of the aerial bombs currently in the northeast are also transferred to northern Shanxi.

And in order to be in the situation that most of the aviation forces, especially the bombers, have been transferred to the northern battlefield to participate in the war. Yang Zhen requisitioned the American-made B-25 bomber that landed in the northeast base area after the US air raid on Tokyo on 18 April, along with the original crew.

In Yang Zhen's view, no matter what kind of army you are, since everyone is now a grasshopper on a rope. Then there is absolutely no friendly army of your own fighting here, you have rested in the base area of the Anti-Japanese Union, and it is a good thing to pat your ass and leave. Since he came, if he didn't do something, wouldn't it be in vain that Lang wasted the excellent performance of the B-25 bomber?
