Half a month has passed since the Manchu court decided to withdraw from Beijing.

Half a month, if it is an army, is enough to walk from Beijing to Liaodong. But now it is not only the army, but the hundreds of thousands of Manchu Qing people in Beijing. It is the wife and concubine of the Manchurian aristocracy, the family of the children, and the old and weak women and children of all the Eight Banner soldiers.

In every Manchu family, in addition to the men in the family, there are also women and children, as well as clothed slaves, and too many properties that are unwilling to give up. The adult males were drafted into the army, and all that remained were the old and weak women and children, as well as the clothed slaves. Hundreds of thousands, towing families and mouths still have to carry a lot of property, and the time to retreat is simply not possible.

The families of the Manchurian nobles also said that they were the first to retreat, and with the help of the army, they had already passed through the Shanhai Pass and entered the Liaoxi Corridor. But ordinary flag people are not so fast. The family walks with a mouth, and he can't walk more than twenty or thirty miles a day.

Fortunately, they went to Shanhaiguan from Beijing through Jizhou, which was different from the path of the Ming army that came from the south, otherwise they would have been intercepted by the Ming army.

At the head of Shanhaiguan City, looking at the Ming army troops that appeared outside the city, and looking at the situation of the Ming army's banner waving like a rainbow, Dai Shan and Luck De sighed long, the Ming army was stuck in the main road to Shanhaiguan, and there was no way.

Outside the Shanhai Pass, the cavalry of the Ming army was vertical and horizontal, countless Manchu people who had not yet entered the customs were impacted by the Ming army, the cry shook the sky, the hateful Ming saber stabbed the spear, the sound of fire guns sounded into a piece, every moment there were Manchu people fell in a pool of blood, and the soldiers of the Eight Banners who saw the closure were filled with righteous indignation and tears.

"Prince Li, please allow me to fight the Ming army!" Lucketthun knelt on the ground and pleaded with Daishan.

"Fight, what to fight? Don't you see that the number of Ming troops outside the Guanhai is 50,000 or 60,000, how much is the total strength of our Shanhaiguan? Plus your cavalry is less than 10,000 people, how can you fight with the Ming army? Dai Shan scolded angrily, watching his people being killed by the Ming army, he was also uncomfortable.

"However, there are still 100,000 people outside the gate, all of whom are the families of my Eight Banner Warriors!" Luck howled, tears streaming down his cheeks.

"There are more people entering the customs, and only by guarding Shanhaiguan can we make more people return to Liaodong safely. If Shanhaiguan Pass is lost, it will be difficult for the hundreds of thousands of people who leave the customs to escape the pursuit of the Ming army. Dai Shan said bitterly.

"Ah!!h Luckard howled in pain, pounding his hand against the wall, and the flesh of his fist flew wide.

Seeing Luckedhun's self-harming appearance, Daishan showed a painful look in his eyes, and ordered someone to pull Luckedhun's arm.

"Luck Dehun, you have done your best, without you leading the cavalry to delay, the Ming army would have come to the outside of Shanhaiguan long ago, and there will be more people intercepted by the Ming army.

Now that your mission has been completed, take your cavalry and go to Ningyuan to join the imperial court. Ningyuan still has more than 20,000 Ming troops, and you need to deter them, so that more people can return to their hometown in Liaodong safely! ”

......

Outside the city of Shanhaiguan, Chen Yue took the main force of the Ming army to garrison the west bank of the Shihe River, and observed Shanhaiguan, the world's first Xiongguan, at close range.

Shanhaiguan is close to the mountains and the sea, stuck in the throat of the Liaoning West Corridor, from the Yanshan Mountain in the north to the Bohai Sea in the south is only a few miles wide, which is actually the narrowest place in the West Liaoning Corridor.

Shanhaiguan Guancheng stands on the main road leading to the corridor of western Liaoning, in addition to the Guancheng with a circumference of four miles, the city of Dongluo and Xiluo City are built around the Guancheng, the north and south wings of the city, and the Guancheng is connected by the city wall, up the mountains and down to the sea, forming a complete defense system.

If you want to defeat the Shanhaiguan, you must first break through the Xiluo City outside the Guan, and then you can attack the Guancheng, and the Guancheng has an urn city, and there are five enemy towers at the head of the city one mile wide, and it is difficult to attack head-on.

A few years ago, Li Zicheng came to Shanhaiguan with a hundred battles and a sharp spirit to break through Beijing to destroy the Ming Dynasty, and fought with Wu Sangui's Guanning army repeatedly, but failed to break through the city.

And now, looking at Shanhaiguan Guancheng, Chen Yue's expression was very solemn. The Qing army did not deploy troops outside the pass, nor did it try to rescue the Manchu people outside the pass who were intercepted and killed by themselves, indicating that the Qing army had made plans to defend the pass. If you want to enter the customs to chase and kill the Manchu brigade that escaped, you must forcibly break through the customs. However, looking at the sturdy Guancheng in front of him, Chen Yue knew that it would be difficult to forcibly break through the pass, and he would inevitably pay great sacrifices!

However, Wu Ping is still blocking the main force of the Qing army in Ningyuan, if he does not break the Shanhai Pass, can he hold Ningyuan with only Wu Ping's 20,000 partial divisions, and can he cut off the retreat of the Qing army?

"Lord Wang!" Jin Xin led the rear army to the outside of the pass, and came to Chen Yue to ask for an order, "Lord Wang, the last general is willing to lead troops to attack Shanhaiguan!" ”

Chen Yue shook his head: "It's too difficult to forcibly break through." Jin Xin, I will give you 20,000 troops, you go north to bypass the Shanhaiguan, try to cross the border wall, and break through to the Shanhaiguan. ”

After Li Zicheng was defeated in the Battle of Shanhaiguan, Chen Yue specially learned about the battle situation at that time from Hao Shaoqi, who surrendered, and Hao Shaoqi's subordinates had many soldiers of the Shun Army who participated in the battle of Shanhaiguan, and gave a detailed description of the battle that took place in Shanhaiguan at that time.

And now, Wu Sangui, the protagonist of the Shanhaiguan War, is in his own army, which makes Chen Yue more familiar with the terrain of Shanhaiguan.

According to Wu Sangui's report, Shanhaiguan is too strong, and if it is forcibly attacked, it will inevitably pay great sacrifices, but there is no need to storm Shanhaiguan, because you can choose to go around Shanhaiguan from a stone side wall in the north. The Qing army is too small, there is not enough manpower to defend the border wall dozens of miles long, it is not difficult to break through the past, Li Zicheng sent Tang Tong Bai Guangen from a stone out of the side wall to Shanhaiguan after cutting off Wu Sangui's retreat, if there is no Qing army, Wu Sangui, who is trapped in the lonely city by both sides, will definitely fail.

As long as an army can be sent out of the pass, it can support Wu Ping in Ningyuan and pursue the fleeing Manchu army.

So Chen Yue handed over this arduous task to Jin Xin. Of course, because it was from the mountain across the side wall, the chariot could not be carried, and the army that was in this pass also fell into a state of isolation, Chen Yue repeatedly instructed Jin Xin, telling him to be cautious and not to trap the army in danger.

Seeing that he was given a heavy responsibility, Jin Xin was extremely happy, and promised to take the army to the north. Wu Sangui was sent as a guide to lead Jin Xin to break through the side wall.

Then Chen Yue ordered the remaining more than 30,000 troops to line up outside Shanhaiguan and launch an attack on Shanhaiguan to contain the attention of the Qing army in Guancheng and create an opportunity for Jin Xin to break through the side wall from a piece of stone.
