For Su Yingqi, no matter whether the 32nd Division of the Japanese Army was full, he left himself in Crouching Tiger Mountain and ignored it. Or this 32nd Division does not look down on its own remnants of the defeated generals, and its real intention is to have other plans, which is not the point. The point is that since the Japanese army did not attack itself, the retreat route behind itself was not cut off.

In fact, Su Yingqi didn't know that the reason why the Japanese army around Taiyuan did not attack the front line of Wohu Mountain and let him go at the last moment, except for the great damage caused to the Japanese army by Yang Jicai when he left. The Japanese troops, which had already advanced into and around the city of Taiyuan, had suffered heavy losses in the air raid the night before.

The anti-Japanese air forces stationed in northern Shaanxi and southern Suinan have been dispatched to make use of the fighter units of the Japanese army air force, and at present there is almost no night flight capability. Large-scale bombardment was carried out on the Japanese positions in the south, west, and east of Taiyuan. The anti-United Nations air force has specially practiced a set of night bombing tactics.

Because the main purpose was not to capture the positions of the Japanese army, or to annihilate the living forces of the Japanese army and destroy its field fortifications. Therefore, among the bombs dropped in this night bombing, except for a small number of high-explosive bombs, the main bombs were American-style incendiary bombs and napalm. These incendiary bombs and napalm brought severe casualties to the Japanese army, which was on the offensive and did not have strong field air defense capabilities.

In particular, the 32nd Division, which was subjected to air raids, and the 16 special aerial bombs, even in the mountainous terrain, limited a considerable part of their power. Moreover, the yield of these sixteen special aerial bombs is relatively small compared to the dozen or so used in the Kangbao battlefield.

However, these 16 special aerial bombs still caused the 32nd Division to suffer considerable losses. In particular, on the Mengjia, Xiaoyaotou, and Naoma lines, which were the key areas of bombing, two to three air-fuel bombs were dropped on average in each Japanese assembly area. Although because of the mountainous terrain, the power of such bombs is limited to the area affected.

However, it is precisely because the air-fuel bombs that explode in the ravine are confined to the ravine because the dispersion area is limited to the ravine, but it increases the local power and lethality in disguise. Almost none of the Japanese troops in the selected target ravine survived the explosion.

The 32nd Division, which was fighting east of Taiyuan, did not attack the front line of Wohu Mountain, except for heavy losses in the bombing. A considerable part of the reason was the violent explosion in Taiyuan City, which attracted the attention of the 32nd Division. I really didn't have time to find out that here in Wohu Mountain, there was still a small anti-United Nations force holding on.

In addition, the most crucial point is that the 32nd Division at this time, even if it did not suffer too much losses in the bombing all night, was actually somewhat unable to fight. Behind them, Taihang and the reinforced troops of the Southern Hebei Military Region were unable to contain the actions of the division. However, with the combination of the usual guerrilla warfare and movement warfare, the supply line of the 32nd Division was cut off.

Not to mention that the connection with Zhengding, the logistics supply base of the 32nd Division, was cut off, and even the supply lines with Yuci and Yangquan were also in a situation where they were in a situation where they were connected from time to time. The transport of a consignment of food and ammunition requires the escort of at least one infantry brigade to arrive safely.

But at present, the 32nd Division simply cannot draw so many troops to escort logistics supplies. If an infantry brigade had been drawn from each batch of supplies, the 32nd Division would have to send two-thirds of its troops to protect the supply lines in order to meet the needs.

Moreover, the reserves in Yuci and Yangquan were not able to support too many Japanese supplies. The grain and ammunition reserves in Yuci, which was closest to Taiyuan, were all allocated to the 32nd Division, which could not meet the needs. The Battle of Northern Jin started very suddenly, and the Japanese army did not have time to prepare in advance. Taiyuan was besieged, which was even more unexpected by the Japanese army.

Except for Taiyuan, a transportation hub, which has a large amount of grain reserves, the rest of the bases have not been specially stockpiled in wartime. The amount of all the grain in stock is not very large. Even Yuci, an important stronghold on the Zhengtai Line, could only supply a week's worth of food and ammunition for an infantry brigade. These grains and ammunition were nothing less than a drop in the bucket for a complete division, and the food behind them could not be transported for a long time, and in the last few days, the 32nd Division could only eat an average of one meal a day from top to bottom. More importantly, the ammunition carried by the 32nd Division itself was not only consumed a lot during the battle, but also lost more than half of it in the air raids of the Anti-United Nations.

With the delay in the rear, the daily ammunition ration of its individual soldiers has dropped to 30 rounds. And the reserve of artillery shells has fallen to a dangerous number. Infantry guns and rapid-fire guns, shells are already less than a hundred. Heavy artillery and mountain artillery shells, on average, only ten shells remained per gun.

This is also infantry shells and rapid-fire shells that are used as support firepower at the level of the Japanese army's brigade, and there is a certain amount of stock in Yuci. After the 32nd Division arrived east of Taiyuan, a squadron of the Japanese defenders in Yuci transferred all the shells to the 32nd Division as soon as possible. Otherwise, the current 32nd Division would not be able to make up even a hundred rounds.

What can't be carried at the moment is not only Yang Jicai, who has consumed a lot of troops and is no longer able to continue to defend. There is also this 32nd Division, which is almost cut off from the mouth of the person to the muzzle of the gun. Compared with the troubled 32nd Division, the 41st Division, which fought in the south and west of the city, was much better.

Although the logistics of the 41st Division were already precarious under the harassment of the Taiyue Military Region, they were forced to deploy a large number of troops to escort ammunition and food. However, although the situation barely met its own needs, it was far better than that of the 32nd Division. Moreover, it is backed by Jinyuan, Qingyuan, and Jiaocheng, and can extract a part of the grain.

At the same time, because the marching distance is not so long, the logistical supplies can still partially meet the needs. Although it is impossible to form a reserve, it is much better than the 32nd Division is about to run out. If Yang Jicai was carrying it for a day, I am afraid that it would not be him who would retreat first, but the 32nd Division, which had almost run out of cooking.

Although Su Yingqi didn't know about this qiē, Yang Jicai already knew it clearly from the mouths of the Japanese prisoners. But no matter whether the 32nd Division can't bear it in the first place, this is no different for Yang Jicai. The 32nd Division was now almost cut off, and its only effect was that when it retreated, it would be much less risky to encounter Japanese pursuit.

The 32nd Division, which was eager to enter Taiyuan City to replenish, found that there was nothing left. Even the headquarters of the First Army was already hungry from top to bottom. Not only was it unable to provide supplies to the 32nd Division, but it even had to be reinforced. The 32nd Division, which had no choice but to levy and distribute food on the spot, that is, to grab grain, and sent troops back to Yangquan immediately to rush to transport grain, did not take into account that there was still a small anti-United Nations force in Wohu Mountain.

The 32nd Division ran out of food, and the 41st Division was unable to pursue because of the greater casualties. The main force of the Japanese army along the way has almost been drained, and some of the puppet troops left behind do not dare to make any moves at all, so that Yang Jicai can almost be said to have not been intercepted and pursued by the Japanese army when he retreated.

But the problem is that many times the battlefield is not just facing the enemy, more often than not, the reason for changing the plan is an unforeseen opponent. Yang Jicai, who evacuated at the maximum speed according to the original plan, retreated at a speed after leaving Taiyuan, but the speed of retreat was far from what he planned and imagined.

From Taiyuan to Huangzhai, his train convoy ran for half a day. Otherwise, it would not have been only a few tens of kilometers away, but it was not until noon the next day that Su Yingqi was given the order to retreat. The dilapidated railway facilities, large and small tunnels and bridges have become the reason why the speed of the convoy cannot be improved.

Even in order to ensure the safety of transportation, every time they arrived at a turnout, the personnel of the Jinsui Military Region stationed in the underground working committee of the Tongpu Railway who accompanied the evacuation had to get off the train to check on it. lest the turnout be moved by the Japanese army, and there will be some accidents that should have been avoided. And each train that is obviously overloaded, even if the front and rear locomotives are pushed and pulled one by one, they cannot travel at maximum speed under complex road conditions.

Shanxi is mountainous, and the terrain is relatively much more complex than Hebei. Although when the Tongpu Railway was built, it was avoided as much as possible to avoid overly complex terrain. However, the actual situation in Shanxi is there, and no matter which direction this railway takes, it will inevitably have to pass through countless mountainous areas, large and small, as well as countless ditches and ravines.

And on these ditches, countless bridges have also been erected. Although the number of tunnels in the entire Tongpu Railway is not as good as that of Zhengtai Road, it is enough to make the Jinpu Railway, which is mainly built on the plain terrain, ashamed. Although there was already mental preparation before and a detailed plan was already made. The first qiē operation was also implemented step by step according to the plan, but the speed and efficiency still gave Yang Jicai a headache.

Along the way, it took nearly ten hours for Yang Jicai's convoy to arrive in Huangzhai. If it weren't for the measures taken by Yang Jicai, coupled with the bombing last night and this morning, the anti-Japanese aviation did their best to cover it, and the 32nd Division was unable to pursue because of supply difficulties. At this rate, the Japanese army would have caught up with their butts a long time ago.

Even if it passed Huangzhai, it did not mean that Yang Jicai's retreat had a smooth journey. In order to ensure safety when crossing the tunnel, Yang Jicai had to change his plan and lengthen the time between trains. In longer tunnels such as Tongguò Duanjialing, the delay is longer.

Because these tunnels on Tongpu Road were originally built according to the narrow-gauge railway traffic standards. The height of the tunnels is generally relatively low. Trains carrying equipment can only barely pass through with caution. Otherwise, once there is a scratch during the passage, it is not only the equipment that will be damaged.

What delayed the time was even more time-consuming when the Tongpu Road was built, in order to save costs under the condition of limited funds. Many of the bridges that were supposed to be iron bridges were replaced by wooden bridges. These improvised wooden bridges, which were erected over countless ravines, were simply unable to bear the heavy weight, and repeatedly reduced the speed at which the traffic was not planned.

At the time of these corner-cutting bridges, Yang Jicai had to divide a train into three separate passages. Otherwise, these bridges, which could not bear the heavy load, would have to throw all his convoys into the ditch. Although these bridges are small bridges.

On the contrary, the large bridges on the route have been reinforced by the Japanese army when they replaced the rails and changed the original narrow gauge to standard gauge, and the quality of the original construction was not bad, so they did not cause too much trouble. All trains, basically according to the planned way of travel, are one-time passes.

As for the overloading of the pass, whether it will harm these bridges, that is not something that Yang Jicai has the heart to worry about now. But these are far more than the number of large bridges, erected on countless wooden railway bridges that cannot be bypassed, and cannot be filled, and are basically dry in the dry season, so that Yang Jicai Lang spent a lot of time.
