The defeat suffered by the Later Jin army under the city of Zunhua was not meaningless, for example, when they attacked this Ming army camp now, they learned from the experience of attacking two fortresses outside the city of Zunhua.

Although the trench in front of the Ming army's camp was still a gentle slope on the attacker's side, and the Houjin army could directly rush into the trench to fight on the wall, this time the Houjin army did not take advantage of this, but honestly drove the Xinfu Han army to start filling the trench, as if the trench in front of it was to be filled in first.

Sun Chengzong, who was standing behind the camp wall and watching the battle, was not wearing armor, he was still wearing a bullfighting suit made of red silk yarn. This kind of emperor's special reward is extremely conspicuous on the battlefield because of its bright colors.

Most of the new Han troops, which were used by the Later Jin army to test the attack, recognized Sun Chengzong's uniform and knew that there was a big official here. In this way, the rumor that the emperor is in the camp may indeed be true.

After all, the newly attached Han army is not the Liaodong Han people who have been in gold for a long time after surrendering, and they still have a little reverence for the Ming Emperor. Attacking a stronghold where the Emperor was sitting had already greatly reduced their morale, and they were even more reluctant to face this figure who seemed to be an important minister next to the Emperor.

Therefore, the attacking Xinfu Han army not only did not concentrate in the direction where Sun Chengzong was, but intentionally or unintentionally avoided his direction. As for the Houjin army, it was mainly observing the defense facilities and firepower of this Ming army battalion.

It is no longer a secret among the Jurchens that the Three Banners of the Left Wing of the Jurchens met under the fortress outside the east gate of Zunhua.

Although the Jurchen Eight Banners have always liked to brag about their bow and horse kung fu, they also talk about Nurhachi's mythical record of defeating 800 Yehebu with four people dismounted and shooting when he was just starting out.

If the Ming army on the opposite side didn't have the strength to fight back, they didn't mind stepping forward to show the Ming army the combat skills of the Eight Banners Foot Shooting. However, the battle of besieging the Ming army's fortress taught these Jurchens that no matter how powerful the archers were, they could not defeat the artillery of the Ming army.

Therefore, they eagerly hoped that they could use the lives of the newly attached Han army to test the defensive layout and the number of artillery in this Ming army camp.

However, the ideas of these Tartars are destined to be difficult to realize. Just when the Houjin army drove the Xinfu Han army to start filling in the trenches, Sun Chengzong, who was standing behind the outer wall of the camp, said to Mao Yuanyi: "Pass the order, before the order of the staff headquarters, first, it is forbidden to fire artillery and Dafa tribute artillery that exceeds six catties.

Second, all new artillery pieces are now under the command of the General Staff Headquarters of the Base Camp, and they are not allowed to be fired without an order from the General Staff Headquarters of the Base Battalion.

Third, tell the generals to let their subordinates try to be as restrained as possible when fighting, and not to scare the enemy away. ”

Mao Yuanyi replied with some puzzlement: "Restricting the use of artillery, the lower officials can still understand it, this is for fear of startling the snake."

But what exactly is the reason for the order to let the combat troops relax somewhat? Shouldn't we take advantage of the fact that they are filling in the trenches to kill and injure a large number of them, and force the Jurchen Tartars on the opposite side to take the field themselves? ”

Sun Chengzong looked at the five endless negative soil teams outside the camp wall, and replied with a calm face: "I'm worried that the fight will be too hard, so that the leader of Jiannu on the opposite side will feel that the casualties paid for attacking this big camp are too great, so he simply gave up the idea of attacking and looked for another way out."

If they know the news of His Majesty's departure to the East Road, no one knows if they will lead their troops to the East again.

Therefore, it would be better for them to feel that the defense of this large battalion is not so good, and that they still have a chance to attack with all their might. It's better than making them feel the danger from the beginning, so they are unwilling to commit the real Jurchen's forces.

The more troops they put into it here, and the more fierce the fighting, the safer it will be for Your Majesty on the eastern road.

We have nearly 20,000 soldiers of the new army in the east of Shimenxia, as well as more than 4,000 auxiliary soldiers, and in the west of Shimenxia, there are also Shanxi soldiers and righteous soldiers recruited by Lu Xiangsheng, the prefect of the daimyo.

And His Majesty did not carry many men and horses to the east, and the Ming army on the East Road was ununited because of the new defeat, if these Tartars were allowed to turn around and go east, His Majesty's side would be in danger. ”

Mao Yuanyi paused for a while, then arched his hand and said: "The chief still understands that the lower officials almost made a mistake. I also asked the commander-in-chief to retreat to the second line of defense to preside over the overall situation, and let the subordinate officials arrange it here. ”

Sun Chengzong nodded at him, then turned around and walked towards the rear. Mao Yuanyi, on the other hand, turned around and gave multiple orders to the adjutant general on the side, adjusting the entire defense line in the direction of Houjin Trench.

The main thing was to reduce the number of troops on the frontal line of defense, strengthen the reserves and develop a system of rotational firing.

Regarding the adjustment of the Ming army's defense line, those newly attached Han troops who were burdened with soil and filled trenches were the first to feel it, and the continuous arrow attacks of the Ming army before it suddenly fell to a sparse place.

The Houjin generals who supervised the filling of the trench stipulated that only one round of rest could be rested after three times of negative soil filling, and there were not many new attached Han troops who could complete this goal, but as the attack of the Ming army slowed down, there were more people who survived the three negative soil filling.

However, this result did not restore some morale of the new Han army, but only made the morale of this army even lower. Because although the Ming army reduced the number of attacks, it also had sufficient time to aim and shoot.

Originally, under the cover and shooting of the Ming army, there were many people in the Xinfu Han Army who were only slightly injured, and only some of the unlucky people were killed on the spot or seriously injured and died.

However, after the Ming army slowed down the speed of the attack, the lightly injured people were greatly reduced, but once they were hit by the Ming army, they were killed or seriously injured on the spot.

Previously, when the Ming army covered and shot and filled the trenches, these newly attached Han troops had the idea of getting out, anyway, it was by luck to die or not, as long as they survived the three trenches they could take a breath, so the speed of these Han troops filling the trenches was relatively fast.

But now, these new Han troops have found that they don't have to rely on luck, and after the Ming army launches a round, they will pause for a moment to aim at a new target, and it is safest to throw earth forward in this gap.

After discovering this trick, some of the more flexible Xinfu Han troops subconsciously slowed down their pace, waiting for the Ming army to release a round of bullets and bows and arrows before desperately throwing the earth forward.

After these Han soldiers who discovered the trick survived the three trenches, it was soon spread throughout the newly attached Han army. And the consequence of this is that the speed of filling the trench has been greatly slowed down, because everyone is grinding, expecting others to come forward to receive a round of Ming army shooting.

The consequence of this was that the Ming army was given more time to shoot them, and the casualty ratio of the new Han army increased significantly.

Although some Houjin soldiers who urged the Han army to fill the trenches were dissatisfied with the decline in the progress of the trenches, many of them were more courageous, and even ran to the side of the trenches to whip the Han troops who were cowering and threw the earth.

However, since they discovered that once the Houjin soldiers stepped forward, the Ming army's shooting target would turn to them, this kind of automatic action of stepping forward to supervise suddenly disappeared.

By the evening of the 4th, the trench in front of the Houjin army was only half filled, but the casualties of the Xinfu Han army had already exceeded half.

Huang Taiji originally planned to take advantage of the poor vision at night to let these Han troops continue to fill the trench to reduce the damage of the Han army. After all, there was no place to capture the Ming and use it to replenish the Han army, and once the Han army was lost, it was necessary to mobilize the Mongols or Jurchens themselves to do the most dangerous trench filling work.

However, after the brutal trench filling battle during the day, the endurance of the Xinfu Han army had obviously reached a limit, and the result of the Houjin army driving them to continue filling the trenches at night was that many people began to flee at night.

The poor sight at night obviously belonged not only to the Ming army, but also to the Houjin army. For the escape of the Han army, the Later Jin army was also difficult to control. The Ming army lit an extremely bright lamp on the camp wall, and used the reflection of silver-plated iron sheet to illuminate the trench in front of it as if it were day.

When Huang Taiji found that the effect of filling the trench at night was not as expected, and a large number of Han troops took the opportunity to flee, he stopped the operation of filling the trench at night.

On December 5, in order to prevent the new Han army from continuing to delay time, Huang Taiji ordered Yue Tuo to take his own banner Niu Lu to supervise the battle, and cover the new Han army that filled the trench, and shoot at the Ming army on the camp wall.

More than a dozen chariots were pushed into the trench by hundreds of Jurchen armor soldiers, these chariots were different from the rudimentary products made by the Jurchens themselves before, with the assistance of the captured Ming craftsmen, the shields on these chariots were in accordance with the standards of the Ming army, covered with cowhide and iron on thick wooden boards, and even the small Franc cannon of the Ming people was difficult to destroy.

This weapon used by the Ming people to deal with nomads was learned by Nurhachi and became a sharp weapon used in field sieges by the Jurchen Eight Banners. In particular, the heavy armored soldiers in the chariot arrived at the Ming army array to carry out infantry shooting, and the Ming army was confused and launched a charge, which became the most common field tactic of the Jurchen Eight Banners against the Ming army in Liaodong.

Because of the success of this tactic, Nurhachi once ordered not to fight if the enemy did not have a chariot. So fundamentally, the Ming army was not defeated by the Jurchens' cavalry and archery tactics, but by a barbarian who had learned the Ming army's tactics and used the Ming army's standard weapons.

This time, Houjin detoured into the customs, and naturally he would not bring any bulky cars with him. However, after the defeat of Zunhua City, Huang Taiji selected Ming craftsmen and began to make Nurhachi's improved chariots.

According to Nurhachi's regulations, every 100 men should be equipped with four chariots, of which 30 soldiers should operate them, and the other 70 should be the main force of the battle.

Yue Tuo used 12 chariots this time, which is equivalent to using 300 soldiers with red flags to provide cover for these newly attached soldiers who filled in the trenches.
