The Qing army crossed the Liao River on the ninth day of April, which was the largest use of troops after the Songjin War, and the eight banners of Mongolia and Han all went out to fight, and the eight banners of the Manchurian Eight Banners also recruited seventy percent of the young and strong, with a total strength of 130,000 - Dolgon moved his brain again, only to a small number of old and weak soldiers who stayed in Shengjing, and the hidden dangers of the Mongolian and Han Eight Banners naturally could not be left in the old nest, and even the common people Haoge had to go out with the army.

The first emperor said a long time ago that the Fengzhou soldiers would be defeated when they entered Liaodong, and the Qing soldiers would also be defeated when they entered Fengzhou, and the regent was crazy, and he didn't want to live and dragged us to die - the morale of the Eight Banners was low, and they walked for four days before marching more than 100 miles, and the Mongolian tribes of the outer domains who had made an appointment to meet did not even see a shadow, and Dolgon did not seem to be in a hurry, and led the army to grind slowly on the road.

Empress Weng (now Fuxin), the opportunity finally came, Wu Sangui sent an envoy to send a letter for help - "The king is a hero of the world, on the occasion of the destruction of the withering and decaying meeting, when it is difficult to get it again, begging to read the words of loyalty and righteousness of the lonely ministers of the dead country, and quickly select elite soldiers to enter the China Association and the Western Association. Then those who report to the northern dynasty will not only be rich, but will split the land in return. ”

Dolgon waved back, couldn't help laughing happily, luck is too good, to be honest, he didn't have the courage to go to Datong thousands of miles away to seek death, originally wanted to cross the Daling River Valley, looking for a chance to enter the customs to get a handful, Emperor Taizong was also disgraced when he ascended the throne at the beginning of the year, isn't it just by breaking through the success of the pass to monopolize the power, he can also play the same way, but this step is too dangerous, since Li Zicheng can break through the Beijing Division, his strength cannot be underestimated, he is still a little hesitant, and now Wu Sangui sent a letter asking for help, and he has the bottom in his heart.

"Mr. Hong, what do you think?" Dolgon asked Hong Chengchou with a smile, this person has been in the house for a long time since he returned to Shun, and he has never made a plan, and Emperor Taizong also used him as an ornament, and now it is time to come in handy.

"The minister thinks that this is Wu Sangui's crying blood for help, I can't help it, but I can go out of Jizhen and Miyun, and join forces with Wu Sangui to suppress the thieves." Hong Chengchou replied that he had been incorporated into the Han army with a yellow flag and had an ugly braid.

Dolgon shook his head with a smile, and glanced at Zu Dashou again, this guy is Wu Sangui's uncle, and most of the letters of persuasion written to the generals of the Guan Ning Army came from him, so I still have to listen to his opinion.

"The minister also thought that this was a once-in-a-lifetime opportunity, and my Qing soldiers should enter the customs to suppress thieves." Zu Dashou hurriedly replied, and he was still surprised that his nephew's writing was suddenly much more syldicated, of course he couldn't guess that this was the handwriting of the governor of Jiliao.

"Wu Sangui is not qualified to join forces with this king, reply to him to surrender, if he leads the people to return, allow him to be the king of Tujin," Dolgon laughed again, waved his hand and ordered the generals: "Immediately turn to Shanhaiguan and force Wu Sangui to attack Mingdu." ”

When the Qing army heard about the Ming Dynasty, they immediately became jubilant, and the whole army turned around and headed south, marching 200 miles a day to Shanhaiguan, and arrived at Lianshanbao on April 20, only 200 miles away from Shanhaiguan - at this time, Wu Sangui sent an envoy again to ask for help, asking the Qing army to enter the customs quickly, and Dolgon smiled and sent the messenger away, and ordered the whole army to advance slowly.

One of the two powerhouses of Datong and Qing stood by and watched, and the other grinded, forcing the two supporting characters to the forefront, Wu Sangui reorganized the army day and night, but Li Zicheng arrived late, and did not arrive on the west bank of the Shihe River until the early morning of April 21.

It is not easy for the Shun army to come to this trip, the Beijing division suffered from torture and plunder, the people regarded the Shun army as an enemy, and there was an appointment in the market to raise an incident and support the unveiling post of the East Palace, and Liu Zongmin, Li Guo and others spent all day drinking, and they wanted to return to the old nest with the looted property, and they had no intention of staying in Beijing for a long time. Li Zicheng knew that it was difficult to gain a foothold in Beijing, but he was reluctant to take the opportunity to ascend the throne and become emperor in the national capital, and when he was in a dilemma, the news of Wu Sangui's rebellion came, and then Li Yu sent a letter informing Wu Sangui that he might collude with the Qing army to enter the customs. The generals of the Shun army were angry, shouting and shouting and killing, and even Liu Zongmin and Li Guo jumped out to ask for war - Wu Sangui, a slave with three surnames, was too shameless, not only played a trick on the Shun army, but also sold himself to join the Dongyu, is he embarrassed to go home if he doesn't kill this person? Li Zicheng was also annoyed and angry, this tone was not out of the emperor's taste, leaving Niu Jinxing and his group to prepare for the enthronement ceremony, and the generals led more than 200,000 people to kill Shanhaiguan. However, the Shun army was lazy in Beijing, and when they heard that the war was fighting, they were sluggish, and there were still many people deserting in the army.

Shanhaiguan takes the city of Guancheng as the center, builds four auxiliary cities of Dongluo City, Xiluo City and the south and north wing cities, connects with each other with the Great Wall and Taibao, the south wing city also faces the sea and cannot attack, the whole attack and defense system is impeccable, and the auxiliary city cannot be taken and wants to capture the Guancheng. This battle is not easy to fight, the Shun army is unable to deal with the Qing army and the Guanning army at the same time, must use the advantage of strength to grab time to eat Wu Sangui, and then rely on the side wall to deal with the Qing army - Li Zicheng observed Shanhaiguan, ordered Tang Tong to rush to a stone thirty miles northwest of Shanhaiguan to cut off Wu Sangui's retreat, the main force of the Shun army attacked Dongluo City, Xiluo City and North Wing City at the same time, and the battle of Shanhaiguan immediately began.

The Shun army was numerous, but there were only 60,000 soldiers, and they still used the old method to attack the city, in front of them were carrying ladders and holding hoes, and the common people rushed forward one after another, and the soldiers behind fired volleys with guns and arrows, desperately suppressing the defenders of the city. The Ming army showed a disadvantage when it started the war, Wu Sangui had 40,000 people, Gao Di had 10,000 people, and there were 30,000 village soldiers organized by the gentry, which seemed to be a lot, but the armored soldiers were less than 10,000 people, and the other miscellaneous soldiers were incomplete in weapons and low in combat power, and they were simply unable to stop the flow of people from the black pressure. The Shun army rushed to the city with the corpses of their companions, the brave men climbed up the ladders, and the common people also picked up their hoes and dug the city desperately. Wu Sangui was desperate, personally led the elite cavalry out of the city to counterattack, the cavalry of the Shun army also swarmed up, the two sides went forward and fought for their lives, the Shun army with superior forces gradually controlled the battlefield, and it seemed only a matter of time before the capture of Shanhaiguan, but the danger was approaching.

Tang Tong was full of resentment and went on the road, he only had 8,000 people, not only was he powerless to stop Wu Sangui from escaping, but if the Qing army came to reinforce him, he would be attacked from both sides, and he would be sent to death. The more Tang Tong thought about it, the more afraid he was, the more unlucky he became, not long after arriving at a stone, the cavalry of the Qing army suddenly appeared, and before he could think about what to do, the other party rushed over with a shout, this Shun army was originally a Ming army, and the Qing army was afraid of the Qing army like a tiger, hundreds of people were killed at the slightest contact, and the others did not dare to fight, and habitually coerced the main general to flee.

Baya Lajun Zhangjing Tulai stopped chasing for a few miles, he was not interested in this group of defeated soldiers who played the banner of the Shun army but wore the Ming army uniform, but shook his head and sighed, nearly 10,000 people were easily defeated by hundreds of elite cavalry, it was still the same, it did not change at all, and he continued to search forward with his subordinates - Emperor Taizong died, he also stepped aside, and was sent to be the leader of the white armor soldiers, but this is more pleasant, it is better than seeing that nasty little white face.

Tang Tong gathered the remnants of the army and hid in the mountains, and never dared to show his face again - the Qing army came so fast, this battle of the Shun army will undoubtedly be defeated, it is a blessing to be able to escape this catastrophe, this guy is worried that he will be defeated and convicted, and he intends to block the news from Li Zicheng.

On the morning of April 22, the Qing army arrived at Weiyuan Fort two miles away from the city, Dolgon ordered the whole army to rest and raise a big banner, at this time there were thousands of Mongolian cavalry from the outer domain, these guys did not dare to provoke Datong, they heard that they entered the pass but happily joined in the fun, Dolgon unceremoniously drove them to the west to serve as a guard - he was a little suspicious, always felt that the Datong Iron Cavalry would suddenly appear, Erlu Ke had learned the Huang Taiji Art of War, and liked to play long-distance raids the most, Shanhaiguan did not have to worry too much, someone was more anxious than him, the more intense the fight, the better. Sure enough, it didn't take long for Wu Sangui to break out of the encirclement and run to ask for a meeting, and Dolgon's little heart was so excited that he was thumping, but the shelf still had to be set up.

"You asked me to come, I came, why did you use shelling?" Dorgon asked sharply.

"No, the thieves attacked the city on three sides, and they sent troops to cut off my retreat, so they fired artillery from all sides, and they definitely did not intend to offend the friendly army." Wu Sangui hurriedly argued.

"You have a point," Dorgon nodded, turning his face and continuing to look in the direction of the castle, where the sound of cannons and shouts of killing became more and more intense.

Wu Sangui looked panicked, hesitated for a moment and pleaded: "Nine kings, send troops quickly, although the thieves are rampant, the combined troops of the Ming and Qing dynasties will win the battle, and our country will be rewarded with land and gold and silk." ”

"Wu Sangui, what do you think of what this king asked you to consider?" Dolgon's eyes stared at Wu Sangui and he was silent, sneered a few times and then roared angrily, "What does the Ming Kingdom have to do with my Qing Dynasty, why did our soldiers shed blood for the restoration of the country?" The king's conditions remain the same - shave your hair and surrender, otherwise you will fight down, and this king will only negotiate with the victor. ”

Wu Sangui stood for a long time with a pale face, and finally fell to the ground with a weak leg: "Minister Wu Sangui is willing to surrender!" ”

"That's right, you avenge the old master, the righteousness is commendable, this king also wants the beauty of adults, the Ming and Qing dynasties were enemy countries in the past, and now they are a family, if the Qing soldiers enter the customs if they move a grass and a particle, they will be executed by military law, you can tell the residents of all sizes, don't panic," Dolgon laughed and helped Wu Sangui up, turned his face to the guards and ordered, "Shave General Wu's hair immediately, this king wants to make a blood alliance with General Wu." ”

Wu Sangui surrendered, and let the Qing army enter the city from the South Water Gate, the North Water Gate and the Guanzhong Gate, but Li Zicheng was still struggling to attack the auxiliary city, and he didn't know anything about the arrival of the Qing army - Shanhaiguan was easy to defend and difficult to attack, and the Shun army had no results except for the forced landing of some village soldiers in the north wing city, Li Zicheng changed his playing style, and set up a long snake formation along the Shihe line from Beishan to the sea to lure the defenders out of the city to fight.

"The thief is vulgar, how can there be a victor in a long line?" Dolgon watched from the city tower for a while, his heart was completely steady, and he waved his hand and ordered Wu Sangui to take all the elites out of the city to meet the battle.

At noon, the battle of Shihe entered the climax, five thousand Guanning iron cavalry out of Shanhaiguan, launched an attack in the direction of Beishan, the head of the Shun army was almost instantly defeated, Li Zicheng immediately mobilized the long snake formation to roll back and besiege, the two iron cavalry collided together, the sword light and sword shadow were full of blood, and the sound of war drums resounded for hundreds of miles. The Guanning Iron Cavalry lived up to its name, and successively broke several formations of the Shun army, but more Shun troops rushed forward one after another, fighting one after another, the former died, and the latter re-advanced, the Guanning army was entangled in the dense flow of people and could not accelerate, and people continued to fall off their horses and be chopped into pulp, and the situation gradually deteriorated.

"Brothers, kill thieves, this battle will not stop!" Wu Sangui rushed to the front, roaring loudly and slashing with a knife, there were too many thieves, and they couldn't rush out after killing through a few big arrays, but the Qing army was still waiting, did they have to wait for the blood of their brothers to run out?

"Wu Sangui downhill! The Ming prince and his father are here. Li Zicheng took the crown prince and Wu Xiang to watch the battle, and the Shun army shouted and persuaded him to surrender.

"Don't surrender, brothers, kill the thief!" Wu Sangui's eyes were red, he waved his knife and slashed the Shunjun cavalry in front of him, and rushed towards Li Zicheng's Daxu, Li Zicheng glanced at his opponent with pity, waved his hand, and the soldiers around him shouted to meet him.

The Guanning army was too tenacious, and the three hours of the battle were still fighting to the death, and the Shun army besieged with absolute superiority, but the death was heavy but they couldn't take the opponent, and the elites in the middle and tail of the formation also joined the battle group one after another. Wu Sangui led the Guanning army to break through many times, and was exhausted and fell into a heavy encirclement, and the whole army was destroyed only overnight.

The battle situation in front of him made Dolgon on the city break out in a cold sweat, and he lowered his clairvoyance and sighed in a low voice: "Han'er is so brave, such a mountain of corpses and a sea of blood is still in a fight to the death, and it is difficult for my Qing soldiers to match it." ”

Duoduo snatched the clairvoyant and replied nonchalantly: "Old Fourteen, Han'er has always been like this, but he doesn't have the courage to fight with us, don't be stupid, Wu Sangui is dying, let's go!" ”

"Old twelve, old fifteen, the two of you each bring 10,000 iron horsemen with Zhengbai and inlaid white to attack, remember, attack the tail of the thief formation to the sea, row by row, advance layer by layer." Dolgon laughed self-deprecatingly, waved his hand and gave an order to Azig and Duoduo - the prince and the nobles disobeyed him, and also instigated the minions to cheat and play tricks, and the only ones who could use it were these two brothers and two white flags, and the main reason for not attacking was to worry about losing his old capital.

The wind suddenly rose, 20,000 Qing army iron cavalry rolled over, the white flag was like a wind and tide, the Shun army was dizzy by the dense arrow rain, suddenly "the east is coming, run for your life" The shout came, the soldiers turned around and ran, the others reacted, and immediately fled, and the Shun army collapsed in an instant. Liu Zongmin found that there was a change, and led the Zhongquan pro-army to reinforce, but the chaotic army lost control, everyone was scrambling to flee for their lives, the Zhongquan pro-army not only failed to block the Qing army, but was rushed by their own people, Liu Zongmin also hit the arrow, seriously wounded and fled - the battle situation abruptly changed, the Shun army failed to eat Wu Sangui, but was attacked by the head and tail, Li Zicheng was at the head of the battle to command the siege of Wu Sangui, witnessing the sudden collapse of the whole army so angry that he beat his chest, and the pro-soldiers saw the Qing army approaching, and did not hesitate to help him get on the horse and flee in embarrassment.

Li Zicheng fled, the Shun army was defeated, the Qing army and the Guanning army chased for 20 miles and beheaded more than 10,000 people, and the Shun army that could not escape was pressed to the sea, and countless people drowned in the water. Shanhaiguan victory, Dolgon set up a banquet that night to entertain the meritorious soldiers, in public to fulfill the promise, Wu Sangui, who had made meritorious contributions in the bloody battle, was the king of Pingxi, divided 10,000 horses and infantry, and made him the vanguard, and Azig and Duoduo took advantage of the victory to hunt down the thieves.

Fan Wencheng suggested that to appease the people's hearts, based on the Guannei, and draft a text in spite of illness - "The volunteers are coming, in order to avenge the monarch and father, not to kill the people, and those who are punished today are only thieves, and those who return from the official will be restored to their officials, and those who return from the people will resume their careers, and the teacher and discipline will be strict, and you will not be harmed", Dolgon was very satisfied, ordered to post notices everywhere, and also promised that "all the ministers who return from shaving their hair will be given a higher rank to stay in their original posts."

The Shun army fled to Yongping before stopping, before they had time to catch their breath, and were defeated by Wu Sangui who was chasing, Li Zicheng was annoyed and ashamed, ordered Wu Xiang to be beheaded to show the public, and then continued to run, retreated to Beijing on the 26th, and then slaughtered Wu Xiang's whole family - the more people killed, the more cowardly, this guy did not dare to guard the Beijing Division, on the 29th Wuying Hall held an enthronement ceremony, the Xi'an set was replayed, and on the 30th, the emperor abandoned Beijing and fled south, and ordered the Forbidden City and the nine gates of the Beijing Division to be burned before leaving.

When Dolgon arrived in Jizhou, he heard that Li Zicheng had abandoned the city and fled, so he immediately ordered Azig, Duoduo, and Wu Sangui to chase after the poor Kou and not linger for a moment - Wu Sangui's dream of recovering the capital division was completely shattered, but at this time he couldn't help himself, so he had to lead the army to hurry south, and he still had to do the work of the forward.

Li Zicheng once again the wall fell down and everyone pushed, the Shun army fled to Dingzhou to get Gu Kecheng, Gu Ying's uncle and nephew led the army to respond, frightened and planned to fight a battle, but the general Jiang Zhi who guarded Baoding suddenly descended to the Qing, attacked and killed the Shun army general Zhang Tianlin and his more than 1,000 men who stayed in the city, and Wu Sangui's soldiers were united, the Shun army was defeated in Dingzhou, and then defeated in Wangdu, Gu Kecheng and Gu Ying died in battle, the whole army no longer had the fighting spirit, and the army fled back to Henan - the north was defeated, although Li Zicheng still had the crown of the top Dashun Emperor, but the military heart and the people's heart fell apart, Defeat is not far off.

Dolgon left Jizhou and cautiously advanced westward, the thieves were not worried, but President Li had to guard against it, but the Datong army only showed its face in Changping, eating and chatting with the Qing army forwards, and then generously let Changping retreat to Juyong Pass, it seemed that he had no interest in the Beijing Division, Dolgon was a little relieved, and he mustered up the courage to rush to the Beijing Division.

On the second day of the fifth month, Zhang Jinyan, Zhang Ruoqi and other former officials led the gentry of Beijing to open the city gate to welcome the hero Wu Sangui, but they did not expect to wait for Dolgon, and now it will be wrong, Dolgon entered the Chaoyang Gate with his head held high in a cheer - a heavy rain at night extinguished the fire of the Beijing Division, and the Wuying Hall and Wenhua Hall in the Forbidden City were still relatively intact, but they were also burned full of smoke and dust, and Dolgon announced on the Wuying Palace: "The Ming Dynasty is malfunctioning, and the three salaries are implemented...... There are more grains, summons to buy a lot of eyes, all kinds of private factions take advantage of the people, now with the people, where the positive amount is given, all the additional distribution is deleted, if the officials do not comply, investigate and punish their crimes", "since the chaos of the Ming Dynasty, Diao Feng day competition to set up institutional lawsuits, hurt the wealth and corruption of the vulgar heart, from now on to be restored, where the first year of Shunzhi before the first day of the fifth month of the second day, the crime is exempted from all sizes." The next day, he called Li Mingrui as the waiter of the Ministry of Rites, and Feng Quan, the former scholar of Toushun, presided over the funeral of Emperor Chongzhen, and the Mongolians of the outer domain were also driven out of the customs by him.

The old officials of the Ming State praised the Great New Politics, and the common people were also grateful for the reduction and exemption of Tian Fu, and Dolgon felt that his ass was firmly seated, and sent his sworn friend Tan Tai back to Shengjing with the music to supervise the relocation of the capital to Beijing.
