And at the same time that the 32nd Division completed the breakthrough to Ruyuekou, Yi Liangpin's troops and the 32nd Division fought chaotically. The 21st Division, which had been stagnant in Yanmen Pass, suddenly launched a fierce attack to the north with the whole army. They successively seized the new Guangwu and the old Guangwu, and launched an attack on Shanyin and East Yulin with the situation of advancing in parallel with three wings.

Seeing that the 21st Division finally bit the hook, Chen Hanzhang's heart that had been hanging fell to the ground. Although Mu Changqiu's troops had not yet arrived at the Pingdiquan line, they had not yet been able to seize Laoxian County and cut off the retreat of the 21st Division. And Yi Liangpin, who is now entangled by the 32nd Division, is likely to be unable to get out of Malankou according to the original plan.

However, under the circumstance that the Ruyuekou line had already been broken through on the entire front, Chen Hanzhang knew that he did not have much time to wait for the 21st Division to enter the encirclement. According to the existing situation, Chen Hanzhang gave up the original plan of setting up an ambush on the front line of Hongtao Mountain according to the development of the form.

Immediately ordered the troops deployed at Shentou to force a force crossing of the Sanggan River south of Mayi and penetrate directly into Guangwu Fort to cut off the retreat of the 21st Division. The troops that had originally set up an ambush at Hongtao Mountain attacked on all fronts, and under the cover of Chen Hanzhang's ability to mobilize all artillery fire, they went straight to the road from Shanyin to Yulin. With a cavalry, a rapid assault on the front line of Zhangzhuang. From the east and west, the 21st Division was flanked.

Chen Hanzhang's order to all units was to complete the two-sided attack on the 21st Division within the shortest possible time. In fact, when this situation was reached, Chen Hanzhang had already given up his original plan to encircle and annihilate the 21st Division. Yi Liangpin could not be withdrawn, which meant that he was holding one hand by the Japanese army, and now he did not have enough troops to complete the encirclement of the 21st Division.

In his hands, the armored units that can be put into the battlefield at the first time, except for the armored regiment equipped with T three or four tanks, all the tank units he is currently on the battlefield at Yanmen Pass. There were only two T26 light tank companies, and more than a dozen Crusader tanks that Yang Jicai withdrew from Taiyuan, and the number of tank clusters was not sufficient.

Compared with the insufficient number of tanks that can be put in, Chen Hanzhang's biggest headache is that the number of infantry cannot meet the needs. Although he temporarily changed all the cavalry that could be mobilized into infantry to participate in the battle. But he still made his use of troops, and he felt unusually nervous and insufficient.

Although most of the Japanese army is concentrated in the Datong Basin, which is relatively favorable to the battlefield, it is not a flat river here. Although the Japanese army was not able to seize Hongtao Mountain, the terrain where Guangwu Fort was located was located in a hilly area. The area between Guangwu and Yulinbao is located in the plains. In fact, although Chen Hanzhang is condescending, he is still in the position of a feint when he really starts fighting.

In such a situation, more troops are also needed. Under the condition that the main forces of the 10th Division, which had arrived one after another, had already moved to Ruyuekou, Yingxian, and southeast of Shanyin to deploy defenses and drag the 32nd Division, he really could not muster the strength to encircle the 21st Division. This battle was destined to be a defeat battle from the beginning.

The troops were insufficient, so Chen Hanzhang replaced them with firepower as much as possible. He mobilized all the artillery guns of more than 100 mm caliber that could be concentrated, and pressed the Japanese troops on three sides with fire power and air support. In addition, tanks were used to cooperate with infantry to gradually annihilate the enemy, so as to completely defeat the 21st Division.

Originally, Chen Hanzhang wanted to concentrate the main force of the 1st Armored Regiment, and with the cooperation of the 1st Mechanized Infantry Battalion, forcibly interspersed the depth of the Japanese army. This tactic was used once by Chen Hanzhang on the Korean battlefield. At that time, he also used the tank's mobility, armor ability, and firepower to tear apart the entire defensive circle of the Japanese army along the mountain road, under the cover of limited infantry, by adopting the method of rapid assault in large depth.

In North Korea at that time, Chen Hanzhang was facing a situation that was not exactly the same as it is now. But not only the forces faced a disadvantage, but also had to withstand the suppression of the artillery fire of the Japanese naval fleet. The pressure is no less than the pressure we face today.

In the face of the superior strength of the Japanese army stationed in Korea, Chen Hanzhang used this tactic to show his might on the battlefield and stir up the Japanese offensive. And at that time, after the battle, No. 1 personally gave this tactic a resounding name "tank splitting battle".

The current situation is much stronger than it was in North Korea. Their side had the advantage of firepower, and the Japanese did not have the support of naval guns. In terms of the quantity and quality of heavy firepower, the anti-union on the battlefield in northern Jin even occupied a certain advantage. Although the number of troops was a little tighter, the number of enemy troops in the surrounding area was also greater than that of the original Korean battlefield.

However, Chen Hanzhang believed that under the situation of similar terrain and similar enemy situation, it was absolutely appropriate for him to adopt this tactic. Moreover, the Soviet-made T three or four tanks he is now equipped with, whether in terms of armor protection or firepower, including mobility, are far from being comparable to those Polish and French miscellaneous light tanks of the year.

The power of these Soviet-made T 34 tank 76 mm tank guns far exceeded those French 37 mm short-barreled tank guns. What's more, the firepower and combat effectiveness of the covering infantry now are far greater than they were back then. Copying this tactic in northern Jin will definitely play a decisive role.

But Chen Hanzhang didn't expect that just over a year had passed. At that time, he played an unimaginable role on the Korean battlefield, and even the tactics that were decisive for the stability of the war situation, but in this battlefield in northern Jin, instead of playing the role he expected, he suffered quite severe losses.

The 21st Division had obviously made unusually detailed preparations before the war. Not only when fighting, but also never rashly, always steady and steady. When marching or fighting, they always huddle together, and first control the commanding heights around them. The most critical thing is that each wing is equipped with over-numbered anti-tank guns.

It is not only equipped with a large number of the latest anti-tank guns of the Japanese army, but also equipped with a new type of anti-tank artillery that is far more powerful than the original anti-tank guns of the Japanese army. This new type of anti-tank gun, Chen Hanzhang can get a military guarantee, and it has never appeared in the past.

A company of T 34 tanks of the 1st Panzer Regiment, in cooperation with three Crusader tanks, repeatedly tried to use the mountain road for a quick assault. However, all of them were firmly blocked on the highway by the new anti-tank artillery that appeared in the Japanese army. The power of this new type of anti-tank gun is significantly greater than that of the latest type of anti-tank rapid-fire gun of the Japanese army.

Chen Hanzhang, who was personally in command at the front line, felt that this anti-tank gun was definitely not a Japanese-standard anti-tank gun with the feeling of being the commander of the anti-coalition armored corps. Such artillery at a distance of three hundred meters could destroy the T three or four tanks from the front. And other Japanese-made anti-tank guns simply do not have this ability.

You must know that even the new type of anti-tank gun of the Japanese army can only penetrate the weak parts of the side of such a tank within a few tens of meters. And in the front, if you want to destroy such a tank with a narrow turret front, except for good luck to the extreme, there is no possibility of this at all.

In mountainous warfare, the visual distance in a straight line is relatively short. Moreover, in the mountainous terrain, the low body of this anti-tank gun, in this complex terrain, the anti-United Nations tanks can only break through in a first-line column during the attack. It is very suitable for the Japanese army to rely on the new anti-tank guns and adopt ambush tactics to destroy the T 34 tanks of the Anti-United Nations at close range.

In addition, Soviet-made tanks have a very narrow pitch angle, which means that the range of fire is very limited. The Japanese army also deployed this anti-tank gun on the mountainside, and coordinated with the rapid-fire gun at the bottom of the mountain and the 92 infantry gun on the top of the mountain, which brought considerable threat to the tanks of the anti-United Nations.

The Japanese army often adopted the method of putting the tanks in their own depth at the same time, and first attacking the first and last two vehicles. After destroying the first tank to block the passage, the other tanks that were blocked in the road were eliminated one by one by reversing the fire. Under the blow of multiple firepower at close range, not to mention the T 34 tank of the Anti-United Nations, I am afraid that it will be difficult to resist this tactic even if it is a new tank more than ten years later.

Chen Hanzhang did not expect that he had once displayed his might in the Korean Peninsula tank splitting battle and tank heart-to-heart warfare. In the mountainous area of northern Jinjin, which is also mountainous, it was forcibly contained by more than 30 new anti-tank guns of the Japanese army. After losing a company of T 34 tanks and completely destroying three Crusader tanks, Chen Hanzhang could only stop using interspersed and split tactics.

These T 34 tanks that were destroyed in this battle were the first tanks of this type to be destroyed by Japanese anti-tank artillery after the battle began. This tank, which was also equipped by the Anti-Japanese Union, was destroyed by Japanese anti-tank fire on the battlefield for the first time.

Under the circumstance that the losses were not light, Chen Hanzhang could only use the T 34 tanks as the main tactics of frontal assault and infantry covering the tanks. Instead, direct fire was used to cover the infantry attack, while the infantry was gradually cleared of anti-tank artillery under the cover of tank fire, opening the way for the tank's subsequent attack.

It's just that although the number of tank losses has dropped to an acceptable level, the speed of Chen Hanzhang's counterattack has obviously slowed down. Especially for the implementation of the original plan, it has brought a strict impact and greatly delayed the speed of achieving the goal.

The mountainous terrain of this area itself also limited the use of tanks. The offensive of the Anti-United Nations was cut very messy by the terrain. And this 21st Division, after encountering the counterattack of the Anti-Japanese Union, seized the commanding heights of the surrounding area at the first time. Relying on these commanding heights, they formed a whole defense in a short period of time.

At the same time, the Japanese troops around any of the attacked points will provide fire support and reinforcements at the first time. As if it had obviously been trained in similar terrain, the 21 st Division advanced and retreated in a measured manner during the operation, and its firepower was equipped and deployed quite reasonably. The internal and external lines are tightly coordinated, and its overall defense can be said to be almost watertight.

It is hard to imagine that this is a formation of a Japanese division in the middle of the attack. If it weren't for the formation of the Japanese army, and the place where the battle took place, it would be on the inner line of the Anti-Japanese Alliance. It is easy to think that this is the Japanese army relying on the mountains outside the inner Great Wall, and the anti-Japanese alliance is the side attacking with all its might.

In such a short period of time, the 21 st Division's firepower deployment was reasonably adjusted. In the battle, the tactical use was in line with reality, especially the speed of the transition between attack and defense, which was far beyond Chen Hanzhang's original expectations. Chen Hanzhang's attack was like plunging headlong into the arms of a fire hedgehog.

Although Chen Hanzhang concentrated almost all the artillery cover that he could use, he was unable to divide the 21st Division because of the failure of tactical deployment, and the progress of the battle was extremely slow. The progress in several directions is not very smooth, and even the progress in some directions can be said to be failures.

And the current situation of the entire Jinbei war situation, with the passage of time, in the comparison of the living forces of the two sides, can only develop towards the unfavorable side of Chen Hanzhang. The development of the battlefield does not wait for anyone, time waits for no one, and the most fundamental thing is the speed of change in the situation, which will not leave too much time for Chen Hanzhang.
