In the battle of Yutai, Wu Zheng's preparation was very sufficient.

The army that shook the Qing army head-on, and the 25,000 men of the First Army were transferred from the direction of Jiangdu alone, and as far as this local war was concerned, Wu Zheng had already taken out 30% of the total military strength.

In other words, this battle cannot be lost, and if it is lost, the foundation of the General's Mansion will be moved.

That will set off a series of chain reactions, the biggest consequence of which is that merchants from all over the country will flee the coast in pursuit of advantages and avoid disadvantages, and foreign merchant ships will head north to Tianjin.

This situation may not be a serious problem for the Qing court, which is mainly agriculture and animal husbandry, but for the general's mansion, it is a catastrophe.

Wu Zheng has been walking a tightrope all these years, in fact, at any time, a defeat may become the last straw that crushes this force, in front of interests, there will not be many people who talk to Wu Zheng about righteousness and affection, whether it is a scholar or a businessman, it is still interests that determine their butts, but the degree is different.

In this battle, Wu Zheng was fearless, especially Shen Zhiyuan's sudden return, which made Wu Zheng more confident.

Of the 100,000 enemy troops in Yanzhou, there are 20,000 fewer for no reason, and on his own side, there are 20,000 more.

Of course, this was due to a private deal with Zilharang, and if it were not for this deal, it was clear that the Qing court would not sit idly by and watch Wu Zheng calmly mobilize a large army to form an encirclement of Yanzhou.

Wu Zheng originally wanted to fight in several directions, tighten the encirclement, and then force Dolbo to surrender, and then find a suitable time to put Dolbo back like Bolo, block Zierharang, and prevent him from "covering the sky with one hand" in the Qing court, a divided Qing court, which Wu Zheng is very willing to see.

Ke Aobai suddenly led his army south, which aroused Wu Zheng's vigilance.

Just hit a time difference? Regardless of whether Zilharan is a human or a ghost? Let's take Ziyang first, as for the whole territory of Yanzhou? Then we'll see.

With this in mind? Wu Zheng revoked the previous order to annihilate the enemy as a supplement, that is to say? This battle has been changed to a normal battle to break the city.

Chen Sheng led his troops to storm Yutai, and a field battle outside the city came down? Both sides weighed the other's abilities.

I have to say? The army that Dorgon left behind to his son was indeed strong.

In order to reduce the losses of his own troops, Chen Sheng sent a partial division to capture the Zhailiji of Yutai Xijie, forming a three-sided encirclement? Have you already made Yutai successful? It has become a trend that both sides know well.

At this time, Ganglin and Qi Chongge in Ziyang City panicked.

On the one hand, they urgently asked the Qing court for reinforcements, and on the other hand, they sent people to Jinan Mansion to urge Ao Bai to lead a large army to help.

But it is difficult to save the fire from afar, Ganglin and Qi Chongge made a stupid move at this time, after they transferred 10,000 new troops to reinforce it? and then send out his descendants to reinforce Yutai, so that? In fact, in Ziyang City, the army has been empty to the extreme.

Ganglin and Qi Chongge originally wanted to? Do your best to hold the fish platform and delay until the arrival of Aobai? So how many more days can it last? And then the Qing reinforcements arrived? The siege of Ziyang was immediately resolved.

But they could not have predicted that although the Qing court had the heart of reinforcements, the internal power was far from what the two could imagine.

The Aobai Department was the only reinforcement that the Qing court actually reached Yanzhou in this war.

……。

October 12, early morning.

After the First Army returned from three days of continuous attack, Chen Sheng obtained 36 large-caliber curved guns (similar to the black-hearted cannons of later generations), and under the cover of field direct-fire guns, dozens of pounds of shells were fired into the city like hail.

This "rough" method caused the clay wall at the south gate of Yutai to collapse by more than one-third.

The First Army immediately attacked the city, and the Qing army in the southern city saw that the situation was not good, and began to retreat to the north in large numbers.

When the Northern Expeditionary Army entered the city, they found that behind the south gate, corpses were everywhere, all of which were blown up and mutilated.

The success of the south gate indicates that the fish platform has changed hands.

The partial division deployed by Chen Sheng in the direction of the West Gate became the last straw that crushed the morale of the Qing army in the city.

On the 12th, at noon, the First Army occupied the whole city of Yutai and began to pursue the Qing army fleeing north, sweeping away the remnants of the city.

……。

The battle of Yutai is of great significance.

It was a head-to-head duel, with the two sides having almost the same amount of strength.

It can be said that to a certain extent, the Qing army still occupies a favorable position, after all, it is the defender.

But even so, the Qing army only held for three days before retreating.

The casualty ratio of the two armies in this battle was about one to two, and we were one to two.

To a large extent, this shows that the balance of superiority in the combat strength of the enemy and our enemies has begun to reverse.

The tactical means behind Chen Sheng's "rough" bombardment of the city gate with large-caliber artillery were recognized by the generals of the guards after the war, and they later asked Wu Zheng for equipment, so the four artillery workshops of the Jiangnan Military Workshop once went all out to produce a single artillery.

In the end, he was forcibly stopped by Wu Zheng.

This is not that Wu Zheng is unwilling to reduce the casualties of the siege troops, in fact, this method is too "rough", but everywhere the shells go, it is a mess.

The explosion injured not only the enemy, but also the civilian population of the city, and destroyed not only the city walls, but also the houses.

Wu Zheng's Northern Expedition wanted to regain lost territory, not accept a ruined city that required a lot of manpower and material resources to be invested after the war.

The most important thing is that once you lose the support of the people and are hated by the people, the gains outweigh the losses.

There are policies and countermeasures, which is greatly reflected in the generals of the Northern Expeditionary Army.

They began to circumvent Wu Zheng's ban on a small scale and partially, and Wu Zheng also turned a blind eye to this.

Of course, that's another story.

……。

The fish platform was only guarded for three days.

This made Ganglin and Qi Chongge no longer panic, but jumped.

Although it was learned that Aobai had already gone south, the forward had only arrived in Tai'an Prefecture, and it would take at least two days to reach Ziyang.

In other words, Ziyang City needs to block the enemy's attack for at least three days before it can look forward to the arrival of the main force of Aobai.

The wrong decision to send the defenders in Ziyang City before not only did not serve the purpose of reinforcing Yutai, but because of the scattered army in Yutai, the team structure was disrupted, and the most important thing is that the words and deeds and propaganda of the defeated troops directly led to low morale.

In order to protect the morale of the banner soldiers, Gang Lin and Qi Chongge made another wrong decision, after they withdrew the flag soldiers, they ordered the city gate to be closed.

This is tantamount to giving up the tens of thousands of defeated soldiers who have not yet entered Ziyang.

This decision outweighed the losses, not only angering the Qing troops outside the city who could not enter the city, but also greatly reducing the morale of the Qing troops inside the city.

But Ganglin and Qi Chongge were in chaos at this time, and they were even discussing whether to ask Dolbo to come back to the meeting and calm the situation.

In fact, human nature is basically the same, in the case of life, interests are the most important, and righteousness is secondary.

Ganglin and Qi Chongge turned their backs on Dolbo and went from Fulin, which actually had signs before Dolgon's death, Dolgon originally wanted to do something to the two, but because he felt that time was running out, in order to leave some available people for Dolbo, and balance and contain Shen Zhiyuan's power, this left the lives of these two.
