In the early morning of December 5, when the east was only turning white, the big tent of the Chinese army in the ninja pass was already full of people. Li Hongyuan and all the generals of the Eastern Route Army were summoned here to listen to Li Hongyuan and other staff officers tell the results of the battle plan they had calculated all night last night.

After listening to Li Hongyuan's report, Zhu Youzhen knocked on the desk next to him, and after quieting down the people in the tent, he said: "I have decided to divide a partial division to attack the Santun camp city and implement the battle plan of encircling the point and sending reinforcements.

The general who led his troops to attack from the east bank of the Luan River, I decided to choose Wu Huai. As for Zu Dashou, he followed me and was responsible for the offensive from the west bank of the Luan River.

It was only a day's journey from here to Santun Camp City, and Wu Huai led the partial division to break through directly to the Santun Camp City, and then blocked the connection between Santun Camp City and the outside. It is expected that by the third and fourth days, the Houjin army led by Wu Nag will inevitably make some moves. Then the partial division led by Wu Huai can choose a place to ambush Houjin to rescue the army of Santun Yingcheng.

The main force of our army, which is advancing from the west bank of the Luan River, will slow down its march in the first two days. From the third day, we will attack with all our might, and if the Wunag army does not come to the rescue of Santun Yingcheng, I will give Wu Huai's troops new instructions to cross the Luan River and attack the Wunag army from the rear.

If the Wunag army really sent troops to rescue the Santun camp city, then Zu Dashou would lead the cavalry of his headquarters to assault and strive to attack the Wunag army ambushed by Wu Huai from the west of the Luan River.

In this battle, we strive to annihilate the Houjin clan led by Wu Nag, and for those Mongolian vassal tribes, the 36 Guanmen Division, and the Horqin Division, as long as they do not insist on resisting on the spot, they can force those who surrender to surrender, and those who are unwilling to surrender and want to evacuate, they will also open the net and let him go.

However, for the so-called Ulut Mongol Banner led by Wu Nag, as well as the Jurchen soldiers and horses in this army, no one must be let go. If anyone can stay with Wunag, whether he lives or dies, I will pour wine for him in front of the army.

As long as the headquarters of Wunag is defeated, the main force of our army and the men and horses mobilized at the passes of the Great Wall will be able to attack the Santun camp city without hindrance. Once this city is over, the siege of Zunhua will be lifted.

The Houjin army made a detour to attack from afar, with no rear to rely on, and no internal supporters, and now that both the east and west sides are under attack by our Ming army, they will inevitably retreat.

Therefore, the Santun camp city is the turning point of this war, and as long as we take this city, then we have won this battle by seven points. I hope that all the soldiers will continue to press forward and do their best in the next battle to completely turn the tide of the battle, expel the Houjin Tartars from the pass, and end this war. ”

Wang Zaijin thought about it for a long time, and finally admitted that the readjusted battle plan according to the timetable calculated by the General Staff Headquarters was much more feasible than the immature plan yesterday. Most importantly, this battle plan has already marked out all the risk factors, so as long as it is implemented according to this plan, even if it does not achieve the expected victory, there will not be much loss.

In the present situation, it was obvious that the emperor would not accept his advice to retreat to the rear without a complete victory. Rather than confronting the Houjin army that has failed continuously on the opposite side, and waiting for other variables to occur when the Houjin reinforcements come up, it is better to implement this plan according to it.

The victory was based on the Santun camp city, and the Ming army on the eastern road was also exempted from the risk of fighting with the main force of Houjin. In the face of setbacks, they also happened to retreat to the Ninja Pass, relying on the camp here to resist the Houjin cavalry. In any case, the emperor's safety can be guaranteed.

After Wang Zaijin determined this, he spoke out in support of the emperor's decision. With the support of the military department, Chongzhen's decision is even more difficult for the generals of the Ming Army on the East Road to waver.

Although Zu Dashou was a little unhappy to let Wu Huai get the opportunity to command the partial division, he did not dare to question the unanimous opinion of the emperor and the military department, but praised the emperor's wise decision with a smile on his face.

When the sun rose high the next day, Wu Huai crossed the Luan River with several staff officers and nearly 5,000 cavalry, and rushed straight from the east bank of the Luan River towards the Santun camp city.

Not long after Wu Huai left the camp, Zu Dashou also took more than 2,000 cavalry as the vanguard of the Ming army, sweeping the west bank of the Luan River and the road leading to Qianxi City.

Although there is a city wall surrounded by a city wall in Qianxi, this place is not a county seat. However, the northeast of Qianxi City is adjacent to the Luanhe River, and there are mountains in the west and south, so it has become a place for a merchant to stop on the passage from Zunhua to Shanhaiguan, and it has gradually become prosperous because of the business travel and military exchanges, but it is more lively than Qian'an City.

However, after several changes of hands with the Later Jin and Ming armies, in addition to some old, weak, sick and disabled residents, the young Zhuang either fled over the mountains to the Fengrun and Tangshan areas, or were captured by the Later Jin army and became a member of the new Han army or artisan battalion.

After losing the topography of the Ninja Pass, between Qianxi and Santun Yingcheng, there was only one tactic left for Wu Nag to choose, which was to give full play to the speed advantage of his army, which was dominated by cavalry.

The men and horses of the Mongol right battalion and the Mongol vassal departments were mixed together, divided into dozens of ranger troops, and carried out intrusion operations when the Ming army was marching, so as to delay the march speed of the Ming army.

On the night of December 4, after Wunag withdrew with his army to Qianxi City, he finally stopped Tushetu Khan Oba of the Korqin tribe. Although Wunag, Dudu, and Chahara were unable to punish Oba's actions, the three of them still partially took away Oba's command of the Korqin tribe.

At the strong request of Wunag, Dudu, and Chahara, and out of fear that the Houjin army was still in the rear, Oba reluctantly agreed to hand over the command of the Horqin tribe to his younger brother Budaqi, and agreed that Dudu would stay in the Korqin tribe to supervise the battle.

Wu Nag, Du Du, Chahara and others reorganized the retreating left army soldiers and horses that night, and after collecting the defenders of the Qianxi and Ninja Pass camps, they finally had more than 7,500 troops, including more than 1,500 men and horses from the Mongolian right battalion, more than 1,100 people from the Naiman, Ao Han and other vassal tribes, more than 1,000 people from the 36th Guanmen Department, nearly 3,500 people from the Horqin Department, and about 400 people from the Jurchen Eight Banners. There is also about a bull and a blue banner and hundreds of Mongolian vassals in Santun Camp City.

The men and horses of the Horqin tribe accounted for half of the Houjin army, and the three of them, including Buwu Nag, did not care about the command of this horse. Even if the three of them knew that their actions had aroused Oba's resentment, they couldn't care about it at the moment.

In fact, Budazi, who had taken Oba's place in command of the Korqin tribe, was more angry with the actions of the three Wunag than his brother. Despite the situation, both Budazi and his brother pinched their noses and recognized Huang Taiji's revised covenant, and recognized the Later Jin Dynasty's transformation of the Korqin tribe from an ally of equal status to a vassal subordinate to the Later Jin order.

At this time, the Later Jin had not yet torn the last fig leaf of the Ming Kingdom, although the incompetent Lin Dan Khan was frightened by the Later Jin army, and he didn't even want the foundation of the Chahar Department in Liaodong, and moved to the Hetao area with his direct tribes to rob the pastures of the Mongol brothers.

However, the Mongolian tribes on the steppe, including the Horqin tribe, were waiting for the Ming Kingdom to be revived, and to teach the Houjin a heavy lesson, so that the peaceful days on the steppe could be restored, and the Mongolian tribes could return to their independent and free life again.

If it is said that in the early days when Huang Taiji took the Houjin army to make a detour into the pass, the Jurchens easily captured those passes that were regarded as dangerous by the Mongols, and successively defeated the Ming army in the pass, which made the Mongolian tribes shocked by the strength of the Houjin army, and gradually had a bit of sincere attachment.

Then when the Later Jin army attacked Zunhua and the Ming army began to counterattack from the east and west, and the seemingly powerful Later Jin army showed fatigue, the Mongols' awe of the Later Jin army dissipated somewhat.

If the seemingly powerful Later Jin army, like the Mongols, was still in a state of scorching under the Ming people's cities, then the Jurchens were only reaching the level of Altan Khan.

Altan Khan still wants to submit to the Ming Kingdom, will the Jurchens be any different? Compared with the Mongols, once the sparsely populated Jurchens declined, would they still be able to keep the territory of Liaodong? If you can't say it, you will be driven back to the deep mountains and old forests by the Ming people to dig ginseng and hunt mink.

The Korqin tribe was unwilling to completely surrender even to the Mongol Great Khan, who had served for generations, let alone let them surrender to the Jianzhou Jurchen who came out of the deep mountains and old forests.

In particular, when the Jurchen generals such as Wunag, Dudu, and Chahara began to meddle in the internal affairs of the Korqin Tribe, they completely regarded the Korqin Department as a subordinate Mongolian tribe in the Later Jin Dynasty, which profoundly stimulated Budaqi's self-esteem as the bloodline of the Golden Family.

After Du Du gained the power to supervise the Korqin tribe, he quickly divided this part into three parts, 1,000 men were given to Wu Nag for use, 500 people were under the command of one Jurchen Niu Lu to protect Oba, and Du Du took another Jurchen Niu Lu with Budaqi to lead the remaining 2,000 people.

Du Du actually suggested that it would be safer for Oba to retreat to Santun Camp City first under the protection of this army, but Oba refused. At this time, Oba only wanted to be with his people, and he had to be careful not to be put under house arrest by the Jurchens.

On the morning of December 5, Wunag made a distribution of troops, Chahara with 500 men to monitor the east bank of the Luan River, Du Du and Budaqi led the army to garrison the west of Qianxi City, and he retreated with the main force to the passage from Qianxi to Santun Yingcheng. The two sides supported each other to contain the march of the Ming army.

As for Qianxi City, after seeing that the Ming army had cannons, Wu Nag dispelled the idea of living in this small city. And those Mongols were even more unwilling to give up their mounts and fight a defensive battle with the Ming army
