At about 5 o'clock in the afternoon of October 26, the second year of Chongzhen, Beile Abatai and Azig led more than 5,000 people from the four banners of the left wing and the Mongolian soldiers on the left wing, and arrived outside the Longjing Pass of the Great Wall.

Longjing Pass belongs to the ground of Qianxi, and Qianxi is in the middle of the 1200-mile Great Wall defense line from Shanhaiguan to Jizhen Town, Huanghuacheng, Beijing, and is the most important section of the Great Wall defense line in Jizhou Town.

The rear of Longjing Pass is the Santun camp and Zunhua City, when Qi Jiguang repaired the Great Wall defense line in Jizhou Town, the idea was to use the Great Wall defense line as a cordon, and the Santun Camp and Zunhua City stationed heavy troops as a mobile force, and a certain Great Wall pass was attacked, then from the Santun camp and Zunhua City to transfer troops to support.

The Great Wall of Jizhou is mostly built on the Saibei Ridge, although the height of the Great Wall is between 15-2 zhang, but after standing on the steep ridge, it has become an insurmountable wall. The steep slopes hundreds of meters high on both sides of the wall are covered with dense bushes that are more than one person high, and there is no way to get close.

The only way to pass through this man-made natural hazard is to pass through the various passes along the Great Wall. Longjingkou is one of the easier passes in the vicinity. The northeast and southwest sides of Longjingkou are steep mountains, and only when they reach this place suddenly breaks off and a gap appears.

A river that meanders out of the mountains also happens to turn back from this gap and cross the Great Wall to the south, and finally merge into the Luan River. In previous years, merchants used to follow the fast-flowing river as guides through the mountains to trade with the Mongol tribes to the north.

The valley is flanked by steep rocks, and people walk through it, and even during the day, it feels unusually dim. And the river is meandering, the narrowest point is only more than 200 meters, and there are often boulders in the middle of the river, so the pedestrian's field of vision is quite narrow. One husband is the pass, and ten thousand people are not open, which probably refers to such a terrain.

Longjing Pass was built in this mountain gap, and the gate was built on the west bank of the river. The city is 15 zhang high, 2978 zhang in circumference, there are three gates of south, north and east, and there is also the moon city at the east gate. There are nearly 100 families living in the castle, and more than 200 sergeants are stationed.

According to the idea of the generals who built Longjing Pass, after building the gate here, it would be difficult to attack even if it was one or two thousand.

After the left flank army stopped at a distance of 2 miles from Longjing Pass, Abatai and Azig gathered their generals to discuss how to capture the pass. In the end, it was agreed that 80 elite soldiers would be selected to attack the city gates tonight, and the army would then carry out a surprise attack.

Abatai, Azig and other Jurchen generals had little confidence in this plan, after all, fighting at night was quite risky for outsiders who were not familiar with the geography of this place.

However, the guide sent by Burhatu insisted on the plan of night attack, and this guide was quite familiar with Longjing Pass, and believed that he could attack from the water gate to the east of Guancheng. Longjing Pass has been in disrepair for many years, although the front still maintains an intact city wall, but the city wall in the south of the city has collapsed a hole, and the guards only used a wooden fence to enclose the matter, and did not repair it. Therefore, as long as you select the best people to enter the city through this gap, it is possible to open the gate to the north without having to fight the battle.

There was no need to fight in the city, and this reason immediately convinced the Jurchen generals of the discussion. From the beginning of Nurhachi's army, the Jurchens almost won all the battles in the field, and the only few defeats were the siege of the city, and the result was defeated by the Ming army's counterattack. As for the Later Jin's capture of Liaoshen and other fortified cities, most of them were won by bribing the Ming generals or large households in the city to directly open the city gates.

Abatai and Azig did not support Baylor, who went south to conquer Ming, so they did not want their subordinates to be lost in the brutal battle of the city, so they agreed to the plan of night attack.

The effect of this night attack was very good, although the defenders of Longjing Pass had strengthened their vigilance after receiving the news that Houjin was about to invade, but the long peaceful life had made the Ming army guarding the pass forget how to fight.

Because they had been on guard for a long time, when Houjin broke through the rear city wall into Guancheng, the Ming army finally discovered the enemy invasion. However, for these already malnourished Ming troops, the difficulties encountered by night operations were no less than those of the Houjin army that participated in the night attack. Especially when these Jurchens began to set fire to people's houses in the city, the Ming army, which was still guarding the city wall, suddenly lost control.

Even if the Ming army guards stopped drinking many times, they could not let these soldiers stay on the city wall to defend against the enemy, after all, their families were all in the city's houses.

So, in the early morning of October 27, Longjing Pass was broken by the left-wing army of Houjin, and the Longjing Pass guard committed suicide, and the soldiers and civilians in the city surrendered. When the sky was about to dawn, the Ming army stationed in Hanerzhuang got the news, and sent the deputy general Yi Ai and the general Wang Zunchen to aid Longjing Pass, but at this time the city had been down, and the reinforcements were broken by the left wing of the Houjin, and both Ming generals died in this battle.

On the morning of the 27th, the troops of Sanbeile Mang Gurtai, Beile Dolgon, and Duoduo arrived at Longjing Pass. Huang Taiji originally wanted to take Daishan and Mang Gultai with him to avoid them having any thoughts when the war was not going well. However, after Dai Shan and Mang Gurtai stayed in the Chinese army, they stayed together all day, as if they were discussing something.

Huang Taiji suddenly woke up, he didn't want his trip to be successful, but the three major Baylors over there reached a united front. Therefore, he made an excuse to send Manggultai to the left flank, and at the same time let Dorgon and Duoduo spy on Mangguertai.

The left flank was dominated by two white flags, and the Dorgon brothers were the owners of the two white flags, so even if Manggultai wanted to do something, he had to ask for the consent of the Dorgon brothers.

After Mang Gurtai arrived at Longjingkou, he naturally took over the command of the left flank. Although Abatai and Azig did not support going south to attack Ming, once they broke through the barrier, they immediately wanted to go south to attack Zunhua City, lest the rich people in the city flee.

The two of them felt that as the commanders of the left-wing army, they would inevitably be able to share the bulk of the looted property from this expedition, so their enthusiasm for fighting could not help but rise. But the arrival of Mang Gurtai suddenly shattered the dream of the two.

Abatai and Azig didn't want to go with Mang Gurtai, since the Great Wall pass had been opened, then the people and goods in the pass were already in the pocket of the army, and at this time, of course, they had to lead the army alone to get the most benefits. Therefore, the two of them each asked Mang Gurtai for their lives, one volunteered to fight Hanerzhuang, and the other asked to fight Panjiakou.

Mang Gurtai, who has always been brave and good at fighting, refused the request of the two, he was not as shallow as the two younger brothers, and when he saw that he easily broke through the pass of the Great Wall, he changed his position. The greater the exploits of this war, the more loot he obtained, and the higher Huang Taiji's prestige in Houjin, so how will the three of them deal with themselves at that time?

Mang Gurtai, who was standing on the ruined wall of Longjing Pass, took a look at the scenery in the south, and then lazily said to the generals who looked puzzled: "Didn't Sibeile say it before? This time, those who refuse will be killed, and those who surrender will not be disturbed. Do not separate the captive from his father and his wife. Do not commit adultery to women, do not strip people's clothes, do not destroy the utensils of houses, do not cut down fruit trees, and do not drink alcohol. There is no forgiveness for violators. Gushan Ezhen can't help it, and the sin is like this.

In that case, we should salute before we fight, and then ask them if they are willing to surrender, and then attack them. Otherwise, wouldn't it be a violation of the military orders of the Four Baylors? This is also for your own good, so that you may not have sinned against the law of the four beles. ”

Abatai was silent, as Nurhachi's concubine, he has not been favored by the old slave, and even the current Baylor was canonized by Huang Taiji, so he dared to get involved in the struggle between the four Baylors.

Azig was still a little unwilling and said: "We are now in the enemy territory, the enemy is outnumbered and I am outnumbered, the enemy is scattered and our army is concentrated, we should fight fast and slow now, how can we give the Ming people time to persuade them to surrender?"

It's better to drive the army to the city, if the enemy is willing to surrender, everyone will naturally be happy, if not, you can attack directly, there is no need to waste time. ”

Dodor wanted to say something, but was held back by Dolgon. Mang Gurtai quickly reprimanded Azig, not only pointing out that he had made decisions on behalf of Dordor before, but now he continued to discriminate between superior and inferior, and dared to question his own orders as the chief general of the Great Baylor and the left, which was simply arrogant.

Azig's face turned blue as he was trained, but he finally didn't say anything more. No matter how unreasonable Manggultai's words were, he was no longer the son he loved by Nurhachi. The four major Baylors have always been eyeing Niu Lu in his hands, and last year Huang Taiji took away the position of the owner of the white flag by cutting off the head of the flag. Azig didn't think that if Mang Gurtai was to trouble him, someone would come forward to intercede for him.

By reprimanding Azig, Mang Gurtai finally established his command on the left flank. Sending people to recruit the Ming army in Hanerzhuang and Panjiakou also became a foregone conclusion.

The defenders of Hanerzhuang sent reinforcements to support Longjing Pass, but they were defeated by the left wing of the Houjin, and at this time, the news of the fall of Hongshankou in the west also reached Hanerzhuang. The east and west passes of Hanerzhuang have fallen, and the small city of Hanerzhuang has become unsafe.

According to the rules of the Ming army in the past, the defenders of Hanerzhuang were either killed in battle or surrendered. However, after the General Staff formulated new battlefield rules, it gave the Han'er Zhuang Ming Army a third way.

Therefore, Mang Gurtai was soon rewarded, and the Ming army in Panjiakou was willing to surrender to the Houjin army, except for some soldiers who fled. However, the defenders of Hanerzhuang abandoned the defense of the city, and evacuated with the residents of the city, and before they left, they set a fire to burn down the houses and baggage of Hanerzhuang.

After hearing the news, Mang Gurtai finally couldn't sit still. Now the weather has begun to approach 0 degrees at night, if these Ming troops burn houses at every turn, the Houjin army will not be able to sleep in the wild every day.

After Mang Gurtai wrote a letter to Longjing Pass to warn the general soldiers of the Santun Battalion and told him not to harass the soldiers and civilians of Houjin after the surrender here, he set off to Hanerzhuang to station, and sent 100 Yang Guli guards to reconnoiter the terrain outside Zunhua City.
