In the area under the jurisdiction of the First Army stationed in Shanxi, where the Japanese army is most likely to reinforce the Mongolian garrison, there are not only the troops left behind by the Taihang Military Region, but also the main force of the Taiyue Military Region who can go into battle at any time. And the troops of the National Army's Second Theater Command, although
At present, the main focus has been on preserving strength, and it has rarely participated in the battle against Japan, but it can at least contain part of the First Army's strength.
The extremely shrewd commander of the second war zone, although the current war against Japan has focused mainly on the most basic defense. Moreover, he lost a lot of troops, especially heavy weapons, in the early days of the war of resistance.
The troops that suffered heavy losses no longer posed much of a threat to the Japanese army.
But after all, for the Japanese army, the hundreds of thousands of equipment under his command are not too bad. Although it is not as good as the Central Army at the moment, it is not too bad. The main reason is that the Jinsui Army, which has a large gap in heavy weapons, is like a
It's not a small threat. It's an army of more than 100,000 people who have received military training and has barely adequate equipment, not more than 100,000 pigs.
Although the man's strength was greatly damaged and he could not regain his pre-war strength no matter how hard he worked, since he retreated to Shanxi, the number of times he took the initiative to attack can be counted with a slap. Thank God that the Japanese army did not come to attack him.
He even dared to take the initiative to provoke the Japanese army.
But after all, there were more than 100,000 people, which was a considerable force in anyone's eyes. The Japanese army still had to deploy troops to guard against them. The Japanese First Army had to divide its forces to monitor the second theater and at the same time dispatch
Part of the troops were stationed on the north bank of the Yellow River in southern Shanxi to prevent the troops from the First World War Zone that faced it across the river from counterattacking in the Zhongtiao Mountains.
In addition, at this time, three main regiments had completed the re-equipment, and other units had also been enriched with the re-installed weapons. On the original basis, an artillery regiment and an artillery battalion were formed using the received artillery.
With the cooperation of the Taiyue Military Region and the remaining troops of the Taihang Military Region, the number of troops that the First Army could send north to reinforce the Mongolian garrison was limited.
The most critical thing is that in the eyes of the Japanese base camp, it is still unknown whether the Chabei area with barren land and poor people will become an area that the Japanese army desperately fights for. The Japanese Mongolian Army's garrison is mainly concentrated in the Chanan area, and Chabei has always been its area.
Weak areas of defense.
Because the Chabei area is close to Outer Mongolia and is subject to its desert and grassland terrain, it is conducive to the highly mechanized Soviet army to exert its firepower and mobility. As well as the insufficient number of Japanese vehicles themselves, the distance between long-distance railway lines and big cities is
Under the circumstances, it is relatively difficult to supply large corps.
Therefore, compared with the Chanan area, the Japanese and puppet troops in Chabei are much weaker. Choosing the breakthrough point here can achieve the greatest results in the shortest time. At the same time, one unit can quickly move south to seize Yinshan before the Japanese and puppet troops.
Various passes in the mountains were built to prevent the Japanese and puppet troops in Chanan from counterattacking towards the Chabei area.
In short, it is a sentence. In Yang Zhen's opinion, either don't do it or do it to the end. Instead of placing the main target in the Cha'nan area, which has little room for maneuver and is surrounded by enemies on three sides, it is better to make an effort and focus on the Cha'nan area north of the Yinshan Mountains.
The northern region is the main operational target. At the same time, we strive to capture the entire Suiyuan in one go and directly open the communication line with the Shanxi-Suiyuan Military Region.
With the Shanxi-Suiyuan Military Region and the Northwestern Shanxi Anti-Japanese Base Area as the entire transfer station, the Northwestern Shanxi Anti-Japanese Base Area is adjacent to the Shaanxi-Gansu-Ningxia Border Region to the west, facing the Shanxi-Chahar-Hebei Military Region across the Tongpu Railway to the east, and only across the Zhengtai Railway from the Taihang Military Region.
Although its geographical location is not as good as the Shanxi-Chahar-Hebei Military Region in the middle of the four anti-Japanese base areas behind enemy lines in North China, it is not much different from the Shanxi-Chahar-Hebei Military Region.
In terms of contacting the central government, the Shanxi-Suiyuan Military Region, which is separated only by the Yellow River from the Shaanxi-Gansu-Ningxia Border Region, still has a certain advantage. The only disadvantage is that it is relatively far away from the anti-Japanese base areas behind enemy lines in Shandong and the Hebei, Shandong and Henan anti-Japanese base areas to the south.
Far away. But its role as a transfer station is still enough. Moreover, the enemy situation around Jinsui is better than that in Shanxi-Chahar-Hebei.
The reason why Yang Zhen did not choose Cha'nan was that, in addition to the narrow terrain and little room for maneuver, another reason was that he would launch an attack directly from Rehe to Cha'nan. Regardless of whether he wanted to or not, he would have to face the strong defenses of Zhangjiakou and Datong.
A city with many defenders.
Although there is only one independent second mixed brigade in Zhangjiakou, the strength of the Japanese army is not as good as that of Datong. However, Zhangjiakou is not only the location of the Japanese Mongolian garrison headquarters, but also is quite close to Baoding, Chengde, and Peiping in a straight line. If Zhangjiakou is
When the attack was launched, not only the Kwantung Army, but also the Japanese North China Front Army would be fully involved.
In other words, the Japanese North China Front is not only maintaining its current status of sweeping up the rear bases of eastern Hebei and northern Hebei, as well as the blockade of the Great Wall inside and outside, but will inevitably involve all of them. Without Zhangjiakou, this is a foreign country.
The important ground was impossible for the Japanese army, whether it was the Kwantung Army or the North China Front Army, to accept.
You must know that if you break through the Zhangjiakou line, there will be no barrier in the entire north of Peiping. From here, you can threaten Peiping to the southeast, tear up the Great Wall to the south, and invade Shanxi to the west. After the July 7th Incident, the Japanese army was
They started from Zhangjiakou and attacked westward. After capturing Datong, they quickly went south to engage with the Second Theater in the Xinkou area to launch a large-scale Battle of Xinkou.
Zhangjiakou is only a hundred kilometers away from the Sino-Mongolian border. It has been a military center since the Qing Dynasty entered the customs. Even until decades after the founding of the People's Republic of China, it was a place where heavy troops were stockpiled. During World War II, the Japanese army used to prevent the Soviet-Mongolian army from cutting off
The connection between the Japanese Army in North China and the Kwantung Army was that a large number of permanent fortifications were built here regardless of manpower and material resources. Choosing Chanan as the main breakthrough point will undoubtedly lead to a long-term battle, which is not what Yang Zhen wants to see.
Yang Zhen is not too worried about the involvement of the Japanese North China Front Army alone. But if the Kwantung Army is also involved, then it is something Yang Zhen does not want to see because he does not want to weaken the Japanese military's combat capabilities too much before the Pearl Harbor Incident.
.And once the two major Japanese strategic groups are deployed, even if they have the advantage in equipment, the troops in their hands are still insufficient.
As for Datong, although the surrounding Japanese troops can mobilize less troops and the speed of reinforcements is not as good as Zhangjiakou, the Japanese troops stationed in Datong themselves are far more powerful than those in Zhangjiakou. The 26th Division is the only field field of the Mongolian garrison.
The division was stationed in Datong.
If you want to open up a straight line with the Shanxi-Chahar-Hebei Military Region, it is impossible to go west to northern Shanxi or east to Zhangjiakou and Datong in northern Hebei, two cities where the Japanese army is heavily stationed and has built a large number of solid fortifications.
Avoid. Instead of wasting troops and wasting time under the two fortified cities and the Japanese military fortifications north of Zhangjiakou, it is better to shift the strategic target to Chabei.
Taking advantage of the grassland terrain in Chabei that is conducive to mechanized operations, and taking advantage of having a large number of tanks and other mechanized equipment on hand, they adopted ground-air coordination tactics to engage in a decisive battle with the Japanese garrison in Mongolia in the field. They strived to defeat the Japanese army in one go.
The main force of the Mongolian troops stationed in Xinjiang has completely opened up the communication line through Chabei, Suiyuan, and northwest Shanxi.
After listening to Yang Zhen's idea, the commander and political commissar of the advancing army over there were shocked by this wild idea. Even the political commissar who was drinking water spurted out the water in his mouth. His plan
The basis for this is to completely defeat the Japanese garrison in Mongolia.
Although there is only one field division of the Mongolian garrison, there are also several independent mixed brigades. Although this strength is the smallest among the Japanese troops in North China, it is not easily shaken. Not to mention that it is not bad.
Received rapid reinforcements from Shanxi's First Army.
Yang Zhen's idea of counting on the left-behind troops in the Taihang Military Region and the Taiyue Military Region to hold back the main force of the Japanese First Army is probably quite difficult in the eyes of the two veterans. Even the best of the Taiyue Military Region are there.
, I am afraid that those who want to hold back the main force of the First Army are motivated but unable to do so.
As for the idea of completely defeating the Mongolian garrison, let alone the Shanxi-Suiyuan Military Region and the advancing army that directly faced it. The Shanxi-Chahar-Hebei Military Region, which was responsible for part of the combat mission, stayed in the Beiyue area to persist.
In addition, it does not have this ability.
You must know that the current Chinese army, even the most well-equipped Central Army, may not be able to annihilate a single regiment of the Japanese army by concentrating more than a dozen regiments. In last year's Hundred Regiment Battle, the 129th Division concentrated
More than ten regiments of the main force were unable to encircle and annihilate a Japanese brigade based on the favorable geographical situation.
On the contrary, it suffered a lot of casualties. More than half of the participating troops even lost the battle. After this battle, due to the heavy casualties of the troops, and the main force resting and redressing, they prepared to go north to join the battle. The remaining troops in the base area were
Due to their own reasons, they were actually unable to fight the Japanese army.
It even happened that when the Japanese army was mopping up, a brigade of troops dared to run rampant in the base area. The equipment was too poor and ammunition was scarce. The quality of the troops declined quickly after the expansion. Especially when the main forces were transferred northward, most of the remaining troops were left behind.
The local armed forces were newly upgraded and their combat effectiveness was relatively weak, making the Japanese army extremely arrogant.
The lessons learned from the past made the commander of the advancing army extremely cautious when setting up their marching formation when they first entered Rehe. Even at the beginning, the goal was to concentrate the forces of a regiment to encircle and annihilate a squadron of the Japanese army or a battalion of the puppet Manchukuo army.
plan. If the Japanese army dispatched an infantry brigade, then at least one brigade of troops would be concentrated. Only due to subsequent changes in the situation, the main force was concentrated to fight a decisive battle with the Japanese and puppet troops.
Of course, this also has a lot to do with the fact that the equipment situation has been greatly improved after the army changed its equipment. Not only does it have its own artillery at all levels, but the ammunition supply is still quite sufficient at least for now. But it is also a kind of helplessness due to the pressing situation.
Otherwise, if this situation continues, the troops will starve and collapse.
Moreover, the Anti-Japanese Alliance has now reached Linxi. If the problem cannot be solved in Rehe for a long time, it will also affect the next strategic deployment. Of course, this foundation is based on the fact that the Japanese army in Rehe only has an independent garrison at the brigade level, and the remaining directions are
The Japanese troops were attracted by the Anti-Japanese Alliance.
Even though the equipment of the troops has been greatly enhanced, on the basis that the military quality has not been fundamentally improved, the two veterans believe that more caution is needed during the battle. If the Japanese troops deployed by the Kwantung Army in Rehe are one division,
If the strength of the regiment is not high, then the two veterans will never deploy it like this.
Now Yang Zhen wants to concentrate his main force to defeat a Japanese field division, plus the Japanese First Cavalry Group stationed in the Guisui area, and the Second Independent Mixed Brigade. In the eyes of the two veterans, this is indeed tantamount to going too far.
Toda. In their opinion, without a year of training, even if the main force has completed the re-equipment, the customs troops plus the advancing army will not have this capability at all.
