After more than a month of bloody battles, in the early May of the fourth year of Tang Wude (621), in the Battle of Tiger Pass, Li Shimin led the elite of 3,500 Xuanjia Army, successfully defeated the main force of more than 100,000 Xia troops, captured Dou Jiande, the king of Xia, and created a rare military miracle in the history of cold weapon warfare.

The battle of Tiger Pass ended with a complete victory for the Tang army. This battle also became a key battle to determine whether the Tang army could finally capture Luoyang. The complete victory in the Battle of Tiger Prison Pass mainly produced two benefits for the Tang Dynasty and the Luoyang War.

First, it succeeded in smashing the military alliance between Zheng and Xia.

As mentioned above, after the Li Tang Dynasty completed the strategic plan to consolidate Guanzhong, it began to carry out the next military action, marching into the Central Plains, conquering Luoyang in the east, and destroying the two major separatist regimes entrenched in the Central Plains in one fell swoop.

Li Shimin led the main force of 100,000 Tang troops to the east out of Tongguan and attacked Luoyang, officially opening the prelude to the unification of the Central Plains by the Li Tang Dynasty. At the same time, the Tang Army's eastward crusade also broke the three-legged pattern of Tang, Zheng, and Xia. Out of consideration for his own interests, coupled with the fact that the Tang army was like a bamboo, Wang Shichong was defeated repeatedly; Zheng and Xia became allies, and Dou Jiande led a large army to aid Luoyang, and the two sides formed a unified anti-Tang front to jointly flank the Tang army.

However, the battle of Tiger Prison Pass made all this come to naught, making Wang Shichong and Dou Jiande's attempts in vain. Dou Jiande's entire army was annihilated at Tiger Pass, and his army was defeated and captured, which led to the military alliance between Zheng and Xia, which collapsed in an instant and ceased to exist.

Moreover, in the battle of Tiger Pass, Li Shimin won more with less and defeated Dou Jiande's army of more than 100,000; In fact, with the defeat of Dou Jiande in the Battle of Tiger Pass, the Dou Jiande military group, which once crisscrossed Hebei, has also been completely defeated. If nothing else, just wait for Luoyang to be taken and Wang Shichong's regime destroyed, and the Tang army will sweep through the Hebei prefectures, which will definitely be a success. Therefore, the victory in the battle of Tiger Prison Pass can be described as killing two birds with one stone.

Second, it completely disintegrated Wang Shichong's psychological defense.

Before, several major battles outside Luoyang City, three battles in Beibei, Qianjin Fort, and Qingcheng Palace, Wang Shichong lost his soldiers and lost his generals, and his vitality was greatly injured, so he had to retreat into the city and fight for trapped beasts. In desperation, Wang Shichong sent a signal for help to Dou Jiande, and agreed to flank the Tang army together. He pinned all his remaining hopes on Dou Jiande.

According to Wang Shichong's idea, with Dou Jiande's strong troops, he will definitely be able to break through Li Shimin's interception at the Tiger Pass, and quickly rush to Luoyang City, join forces with him as soon as possible, and join forces with the outside to flank the main force of the Tang army. However, it backfired, and the final result was that Dou Jiande was defeated and captured, and the main force of the Xia army was annihilated. In this way, Wang Shichong's only hope was ruthlessly extinguished.

It should be said that the end of Wang Shichong has arrived. At this time, Wang Shichong lost all his elite soldiers, and the foreign aid army was wiped out, leaving him with only a lonely Luoyang City. Wang Shichong knew that after Li Shimin's victory in the Tiger Pass, the soldiers would inevitably aim directly at Luoyang. When the Tang army approached the city, Wang Shichong felt more and more desperate, and gradually, even he had to give up. Therefore, the victory in the Battle of Tiger Pass hastened the collapse of the Zheng and Xia regimes.

Wang Shichong expected it well, after defeating Dou Jiande's reinforcements, Li Shimin stopped for a moment, and immediately made a move against Wang Shichong and launched a final general attack on Luoyang City. In fact, the victory or defeat of the two sides in the battle of Tiger Pass was undoubtedly a bolt from the blue sky for the Wang Shichong regime!

For example, not long after the Battle of Tiger Prison Pass ended, on the seventh day of the fifth month of the fourth year of Wude (621), the news that Dou Jiande was defeated and captured was once spread, Wang Shichong's camp immediately exploded, and the people were panicked. I thought that the victory was in hand, and it was a good opportunity to turn the tables against the wind. Who knows, it did turn over, but it was Li Shimin and Tang Jun who turned the tables, but the two major groups of Wang Shichong and Dou Jiande overturned, collapsed and sank into the sand, and were defeated.

Therefore, the battle of Tiger Prison Pass came to an end, and the defenders of Yanshi and Gongxian near Luoyang surrendered, and the Tang army captured Yanshi and Gongxian without much effort. At this point, Luoyang's outer barrier was lost, and there was no natural danger to defend. At this moment, the huge Luoyang City is a feast on a plate in front of Li Shimin.

Not long after, Wang Deren, the general of the Zheng army stationed in the old city of Luoyang, actually abandoned the city and fled. The deputy general Zhao Jiqing had no choice but to raise the city and surrender to the Tang army. The situation at this time was very good for the Tang army. Luoyang's defeat has been decided, and Wang Shichong is obviously powerless.

Before Li Shimin went to the Tiger Prison Pass, he left Li Yuanji, the king of Qi, and Qu Tutong, the veteran general, to lead the main force of the Tang army to continue to besiege Luoyang and oppress Wang Shichong. Obviously, Li Yuanji and Qu Tutong's tasks have been completed very well. During Li Shimin's battle with the Xia army at the Tiger Pass, Wang Shichong never broke through the encirclement of the Tang army and joined forces with Dou Jiande, creating favorable conditions for the victory of the Battle of the Tiger Pass and relieving Li Shimin's worries.

Now, Dou Jiande is defeated. Therefore, Li Shimin decided to lead his troops back to the front line in Luoyang, join the main force, and then command all the officers and men of the Tang Army to launch a general attack on Luoyang, forcing Wang Shichong to surrender on his own initiative, and drawing a successful end to the battle of Luoyang.

So, Li Shimin led the elite of the Xuanjia Army and returned to Luoyang. Moreover, in the team that returned to Luoyang, the Xuanjia Army also escorted Dou Jiande, Wang Wan, Changsun Anshi, Guo Shiheng and other important heads of state and military and political dignitaries of Zheng and Xia. Among them, Wang Wan, the eldest grandson Anshi, and Guo Shiheng are all important members of Wang Shichong Group, and they were sent to Tiger Prison Pass to cooperate with Dou Jiande. As a result, in the battle of Tiger Prison Pass, they, like Dou Jiande, became prisoners of the Tang army.

Li Shimin returned all the way back to the division, escorted the prisoner cart of the prisoners of war, and accompanied them until they were pushed to the foot of Luoyang City. After arriving at the city of Luoyang, Li Shimin waved his hand and ordered someone to escort the prisoner car of Dou Jiande and others to the front of the battle, so that Wang Shichong could see it clearly. Wang Shichong stood on top of the city tower, but Dou Jiande was under the city, the two looked at each other from a distance, with mixed feelings in their hearts, talking and talking, they couldn't help but feel sad, and they both cried.

There is no record in the history books about what Wang Shichong and Dou Jiande talked about. It is conceivable that the two of them were once the overlords of the Central Plains, and they also worked hard to defeat the Tang Army, unify the country, and become the masters of the world. However, in the final result, Dou Jiande became a prisoner, and Wang Shichong was about to become a prisoner, and they were all defeated by Li Shimin, a young man in his twenties.

The reason why Dou Jiande was escorted to the front of the battle was that Li Shimin wanted to tell Wang Shichong not to have some unrealistic illusions; Going out of the city and surrendering is his only choice at present. Immediately afterwards, Li Shimin released the eldest grandson An Shi in the prisoner of war sequence, let him enter Luoyang City, and told Wang Shiren the whole process of the defeat of the Xia army. In fact, Li Shimin was giving Wang Shichong an ultimatum, urging him to surrender quickly, otherwise he would break the city in a big way.

The current Wang Shichong is really anxious, and he is in trouble both internally and externally. The current situation is that he can't fight and fight, and he can't defend it, but Wang Shichong is unwilling to admit defeat and doesn't want to surrender to Li Shimin. For a while, Wang Shichong was at a loss and didn't know what to do. What to do? Wang Shichong summoned the generals to discuss countermeasures.

At this time, the problems faced by Wang Shichong were exactly the same as the choices Li Mi faced at the beginning. Previously, the Beibi Mountain army was defeated, and the main force of the Wagang army was completely lost. Li Mi's original idea was to retreat to Luokoucang and make a comeback. It's a pity that it backfired, because Bing Yuan really defected to the enemy, causing Luokoucang to fall into the hands of Wang Shichong, and the success fell short. Now, feng shui takes turns, and now it is Wang Shichong's turn to face a choice, and he has made the same choice as Li Mi.

Wang Shichong summoned the generals to discuss, although he was defeated at this time, he still wanted to last fight to the death, seeking a glimmer of hope. Wang Shichong's idea was this, Luoyang didn't want it, led the few remaining troops in the city, rushed out of the encirclement of the Tang army with all his might, went south to Xiangyang, occupied a place, and took the opportunity to recuperate his wings, so that he could make a comeback in the future and compete with the Li Tang Dynasty.

In fact, Wang Shichong ostensibly discussed countermeasures with the generals, but in fact, he wanted them to stand in line and express his position, hoping that they would follow him, rush out of Luoyang, and go to Xiangyang. Unexpectedly, when they heard that they were going south to Xiangyang, the reaction of the generals was inconsistent, and they expressed their opposition one after another:

The king of Xia, who I trusted, has been captured now, although he has come out, he will not succeed in the end. (Information Governance Guide)

The generals said to Wang Shichong, the strength we rely on is nothing more than the hundreds of thousands of troops of Dou Jiande, the king of Xia. However, now, Dou Jiande has been captured by Tang Junsheng. What's more, outside Luoyang City, the Tang Army is pressing the border, and it is still unknown whether we can rush out. Even if you really break out of the encirclement, when you arrive in Xiangyang, what kind of climate can you achieve when there is no strong reinforcement outside and no male soldiers inside!

In a word, the people's hearts have been dispersed, and in the face of the Tang army's troops approaching the city, Zheng Guo and the whole country, everyone has lost their fighting spirit and given up resistance. In addition, Wang Shichong acted perversely and unjustly on weekdays, and few people were willing to follow him sincerely. Wang Shichong, a generation of heroes, has completely become a loner.

Therefore, in front of Wang Shichong, there is only one way to surrender. The so-called general trend has gone, and he has no power to return to the sky, even if Wang Shichong is unwilling, at this moment, the general trend and the situation are forced, he can only accept his fate and bow to fate. After a fierce inner struggle, Wang Shichong was helpless and decided to surrender in Kaecheng.

On the ninth day of the fifth month of the fourth year of Wude (621), Wang Shichong was dressed in plain clothes, led the crown prince Wang Xuanying and more than 2,000 ministers, went to the Tang army camp to ask for surrender, presented a letter of surrender, and formally surrendered to Li Shimin. Seeing Wang Shichong, a fierce rival who had been fighting with him for so long, he knelt in front of him at this moment. Li Shimin did not get carried away and fell into the ground, but treated Wang Shichong with courtesy. However, Wang Shichong knelt on the ground, sweating profusely, and was so nervous that he couldn't do it. Seeing this situation, Li Shimin said to Wang Shichong with a smile, in fact, he was deliberately mocking him:

Qing often sees a boy everywhere, but now he sees a boy, how can he be so evil? (Information Governance Guide)

What Li Shimin meant by this is that in the past, you always regarded me as a yellow-mouthed child who has not dried up, why did you behave so respectfully when you saw me, a yellow-mouthed child, today! The implication is to say, Wang Shichong, you also have today, I didn't expect to lose in my hands. Wang Shichong is not stupid, of course he can hear the smell of gunpowder in Li Shimin's words, and hurriedly kowtows to apologize and beg Li Shimin for mercy.

With the surrender of Wang Shichong, the battle of Luoyang, which lasted ten months, finally achieved a complete victory. Luoyang City, which was coveted by the heroes, finally became the territory of the Tang Dynasty. The military campaign of the Eastern Expedition to the Central Plains ended with the complete victory of the Li Tang Dynasty. The capture of Luoyang marked the Tang Dynasty's entry into the Central Plains and achieved a decisive victory, and the grand plan of dominating the world is just around the corner!

Of course, the forced landing of Wang Shichong and the capture of Luoyang do not mean a complete victory. At this time, the Li Tang Dynasty did not fully control the situation in the Central Plains. After the war, there is still a lot to deal with the aftermath. The capture of Luoyang was only a military victory. What Li Shimin has to do next is to stabilize the situation in Luoyang, clean up the hearts of the people in the Central Plains, and defend the fruits of this hard-won victory.

How to stabilize the situation in the Central Plains? It can be summed up in two words: appeasement. Li Shimin knew very well that during Wang Shichong's occupation of Luoyang, due to his perverse actions, the entire Luoyang City was in a miasma, the people's livelihood withered, and starvation was everywhere. The once prosperous and wealthy Eastern Capital has become a hell on earth, and the people are struggling to make a living.

If the Tang Dynasty continued to oppress and exploit the people like Wang Shichong, it would only exacerbate the increasingly bad chaos in Luoyang and intensify the contradictions. At that time, it will inevitably lead to the Tang Dynasty having just defeated Wang Shichong and Dou Jiande, the two strong enemies, and will be dragged into the abyss of civil war, which will outweigh the losses. Therefore, in order to stabilize the situation in Luoyang, we must not intensify the contradictions, but should focus on calming the people's hearts and let the people of Luoyang get out of the wounds of the war as soon as possible.

First of all, when the Tang army was stationed in Luoyang, the first important thing Li Shimin did was to restrain his subordinates, strictly enforce military discipline, and do nothing wrong to the people of Luoyang. As we all know, at the beginning, Li Yuan and his son raised troops from Taiyuan, and the reason why they were able to advance into Guanzhong and conquer Chang'an in a short period of time was because the 30,000 righteous army led by the Li family father and son had strict military discipline and no offenses in the autumn, and won the support of the military and people in Guanzhong, so that they could quickly achieve victory and achieve the imperial cause.

Therefore, this time when he captured Luoyang, Li Shimin continued to carry forward the fine style of attacking Guanzhong, restraining the army and pacifying the people. In Li Shimin's view, the top priority at the moment is to maintain the normal order of Luoyang City, so that the people's lives can return to the right track as soon as possible. According to historical records:

So part of the armies entered Luoyang first, guarded the city, forbade invasion, and no one dared to offend. (Information Governance Guide)

Li Shimin ordered a part of the Tang army to enter Luoyang first, and the army then entered the city. After the Tang army entered the city, it did not wantonly disturb the people, nor did it burn and loot. On the contrary, as soon as the vanguard of the Tang army entered the city, they immediately controlled Luoyang's important transportation arteries and trade markets, and divided their troops to guard them. Moreover, before entering the city, Li Shimin and the soldiers of the Tang Army agreed on three chapters of the law, strictly prohibiting the abduction of the people. Therefore, the officers and men of the Tang Army resolutely carried out the military orders of the King of Qin, and the autumn did not commit any crimes, and quickly stabilized the social order of Luoyang City.

On the tenth day of the first month of May, Li Shimin led the main force of the Tang Army and officially entered Luoyang. At this point, the eastern capital of Luoyang changed hands, Luoyang City, and the Tang Dynasty flag was hung high; The land of Luoyang and Henan was included in the territory of Li Tang. So, after entering Luoyang, how will Li Shimin appease the situation in Luoyang?

First of all, after the main force of the Tang army entered Luoyang, Li Shimin appointed his right-hand man, Ji Room Fang Xuanling (a famous virtuous minister in the Tang Taizong period and one of the "Twenty-four Meritorious Heroes of Lingyan Pavilion"), to go to Zhongshu Province and Menxia Province to collect atlases and books and edicts during the Sui Dynasty. It's a pity that Fang Xuanling was a step late, and those important books had already been burned by Wang Shichong, and by the time they were discovered, it was already too late.

Since all the books have been burned, it is a matter of second best. Li Shimin ordered Xiao Yu, Dou Liang and others to seal the Luoyang Treasury, take out all the gold and silk property, and reward the meritorious soldiers. This was also agreed in advance between Tang Gaozu Li Yuan and Li Shimin and the front-line soldiers before attacking Luoyang.

Through a series of measures such as appeasing the people, collecting classics (unsuccessful), and rewarding soldiers, Li Shimin initially stabilized the situation in Luoyang and did not let Luoyang riot after the war. It should be said that in stabilizing Luoyang's politics, the Tang Dynasty achieved remarkable results in the first step.

Generally speaking, Li Shimin's policy for stabilizing the situation in Luoyang is to be lenient and appeased, treat the people well, and maintain public order. However, leniency does not mean leniency. treats the people, Li Shimin is naturally Huairou, and he has not committed any crimes in autumn. However, Li Shimin's treatment of another group of people was very harsh. What kind of people? That is, in the Battle of Luoyang, some of the most heinous war criminals.

These heinous war criminals are all former important henchmen, cronies, and minions of Wang Shichong. They followed Wang Shichong, acted for the tiger, and aided the abuse, making the people of Luoyang restless and the people's grievances boiling. Therefore, these people must be killed no matter what, and not killing them is not enough to make the people angry.

At that time, when Wang Shichong surrendered to the Tang Dynasty, there were more than 2,000 civil and military officials in Luoyang who surrendered with him. Most of them are insignificant little people, and the crimes are not so big. As a result, many people have been forgiven and forgiven. From among more than 2,000 people, Li Shimin selected more than a dozen people who committed the most heinous crimes, and they were punished in a canonical manner.

These dozen people are Duan Da, Wang Long, Cui Hongdan, Xue Deyin, Yang Wang, Meng Xiaoyi, Shan Xiongxin, Yang Gongqing, Guo Shizhu, Guo Shiheng, Dong Rui, Zhang Tonger, Wang Deren, Zhu Cang, Guo Shancai and others. Li Shimin ordered them all to be beheaded on Luoshui.

It is worth mentioning that among the more than a dozen war criminals who were executed, Shan Xiongxin was also included. Shan Xiongxin was a powerful general when he was in the Wagang Army, with strong martial arts and brave and good at fighting. If Shan Xiongxin can be recruited to Tang Jun's account, it will naturally be better.

What's more, Li Shimin has always loved talents, and his advisers are like clouds, fierce generals are like rain, Fang Xuanling, Du Ruhui, Changsun Wuji, Qin Qiong, Cheng Yanjin, Wei Chi Jingde, Luo Shixin, Duan Zhixuan, Hou Junji, these people are all heroes in the world, and they all serve under Li Shimin's account. Just imagine, doesn't Li Shimin know that Shan Xiongxin is a powerful general, but he still insists on executing him, which is obviously a bit unreasonable.

The reason why Li Shimin wanted to kill Shan Xiongxin was mainly because on the battlefield of the Battle of Beipi, Shan Xiongxin almost took Li Shimin's life, and Li Shimin had always been haunted by it, and he had a pimple in his heart. In addition to this reason, there is a more important point, that is, Li Shimin believes that Shan Xiongxin is capricious and an unfaithful and unrighteous person.

Before, when Li Mi killed Zhai Rang, he also wanted to kill Shan Xiongxin and Li Shiyun together. At the critical moment, Shan Xiongxin was so frightened that he knelt on the ground and begged for mercy before he picked up a life. Later, the Beibishan army was defeated, the Wagang army was almost annihilated, and Shan Xiongxin surrendered to Wang Shichong instead, and since then he has been desperate for Zheng Guo.

Judging from Shan Xiongxin's past behaviors, Li Shimin feels that although Shan Xiongxin is brave and good at fighting, he lacks integrity, is capricious, and has milk is his mother. Such a person, if he is attached to Li Tang, must be forced by the situation. One day in the future, Shan Xiongxin surrendered and rebelled, betrayed Li Tang again, and turned to others. Instead of raising tiger legacies, it is better to eliminate hidden dangers now. Therefore, Li Shimin insisted on killing Shan Xiongxin.

However, there is another version of Shan Xiongxin's murder. According to other historical records, the person who finally ordered the execution was not Li Shimin, the king of Qin, but his father, Li Yuan, the ancestor of the Tang Dynasty. In other words, the last person to sentence Shan Xiongxin to life and death was the Tang Emperor Li Yuan:

At the beginning of the Ping Wang Shichong, by his deceased Shan Xiongxin, according to the routine of the execution, the table said that its martial arts are superb, if it is received in the death, will be grateful, can be for the country's life, please redeem it with the official. Gaozu didn't allow it. (The Old Tang Dynasty Book: The Biography of Li Tao)

Whether it was the order of Tang Gaozu Li Yuan or Qin King Li Shimin, all in all, Shan Xiongxin was finally beheaded in Luoshui like the rest of the dozen or so people, and his head was in a different place. So, if Li Shimin wants to kill Shan Xiongxin, will there be no one in the Tang army to intercede for him? The old people of Wagang in the past, did they turn a blind eye?

This is not entirely true, at that time, in the Tang Army, there were still people who interceded for Shan Xiongxin, who was it? Li Shiyun. As early as the Wagang Army, Li Shichang and Shan Xiongxin were well-known generals and fierce generals in the Wagang Army. Moreover, the relationship between the two is also extraordinary, they once swore to live and die together, which can be called a neck-to-neck friend who cut off his head for his life. What's more, Li Shichang himself is a loyal and benevolent person, and when his friends are in trouble, he naturally can't see death without help.

So, Li Shichang went to meet Li Shimin, the king of Qin, and pleaded for Shan Xiongxin. He told Li Shimin that Shan Xiongxin was superb in martial arts and extremely brave; If Shan Xiongxin can be brought under his command, it will undoubtedly enhance the strength of the Tang army, and it would be a pity to kill him like this. In order to let Li Shimin keep people under the knife, Li Shixin did everything at all costs, saying that if he could exchange his life for Shan Xiongxin, he would be willing to give up all the official titles he had obtained.

Li Shimin knows very well what kind of person Li Shiyun is, and I believe that he did not deliberately go against himself. However, Li Shimin had made up his mind and did not agree to Li Shixian's plea, and still insisted on executing Shan Xiongxin. It is conceivable that Li Shiyun must have been very disappointed, and finally retreated in tears.

Before his execution, Li Shichang met Shan Xiongxin for the last time in private. The two old friends said goodbye to life and death, with mixed feelings. Shan Xiongxin knew that his death time was coming, and he thought that Li Shiyun did not go all out to rescue him, so he couldn't help but complain a little about Li Shixian: "I know that you don't do anything!" Hearing Shan Xiongxin's words, Li Shiyun felt very uncomfortable, very guilty, and couldn't save his old friend's life. Therefore, Li Shiyun said this sadly:

I will not hesitate to die with my brother; But since he promised the country in this body, nothing will happen. And after my death, who will look upon my brother's wife? (Information Governance Guide)

Immediately, Li Shiyun cut off a piece of meat on his thigh, stuffed it into Shan Xiongxin's mouth, and said with tears in his eyes: "Life and death are eternal, this meat will return to the soil together!" After that, Shan Xiongxin was sent to the guillotine, and a generation of troubled generals died in Huangquan. After Shan Xiongxin was killed, Li Shixin did not break his promise and adopted Shan Xiongxin's son, which can be regarded as an explanation to his old friend.

As for the other war criminals in Wang Shichong's camp, Li Shimin's treatment of them is different. Those who committed the most heinous crimes had to be killed, such as Zhu Cang, a brutal and murderous and extremely vicious person, Li Shimin included him in the execution list and sentenced him to death.

However, for some war criminals whose crimes were not so big, Li Shimin showed more magnanimity, such as Wei Jie, Yang Xu, and the eldest grandson An Shi, and more than ten others, all of whom were escorted to Chang'an and handed over to the imperial court for disposal. In addition, there are some innocent people who have been detained by Wang Shichong for a long time, and Li Shimin ordered them all to be released. And the people who were unjustly killed by Wang Shichong, Li Shimin specially sent people to sacrifice:

The people were cruel and cruel, and they threw rubble to hit their corpses, and they were like graves. More than ten people, including Wei Jie, Yang Xu, and the eldest grandson An Shi, were sent to Chang'an. Those who are innocent and imprisoned by the world shall be released, and those who have been killed will be sacrificed and condemned. (Information Governance Guide)

Speaking realistically, after the Tang army captured Luoyang, Li Shimin's post-war policy was still based on pacification and stability. Although, Li Shimin once ordered the execution of a group of war criminals of Wang Shichong's group. However, only a dozen people were killed, and all of them were heinous crimes, and people who deserved to be killed, and never any innocent people were involved. It should be said that the series of measures taken by Li Shimin quickly stabilized the situation in Luoyang in a very short period of time, so that Luoyang quickly returned to the normal track after the war.

Stabilizing the situation in Luoyang was a major breakthrough in the political field in addition to Li Shimin's military victory. This breakthrough was a great victory for the Li Tang Dynasty to win the hearts of the people in the Central Plains and the general support of the military and people in Luoyang after the capture of Luoyang.

The tricky things were dealt with, and the situation in Luoyang City was initially stabilized after the war. Next, Li Shimin set aside a large amount of free time to sit in the gate and meet with the older civil and military ministers in Wang Shichong's group, including Su Wei, a veteran of the Three Dynasties.

Su Wei served in the Western Wei Dynasty, the Northern Zhou Dynasty, and the Sui Dynasty, and was the prime minister of the Sui Wen Emperor and the Yang Emperor of the Sui Dynasty, and participated in the formulation of major policies and laws in the early Sui Dynasty, and was a shrewd and capable minister. Despite this, Su Wei has a fatal weakness, a weak personality and a lack of character.

Historically, Solvay has changed its doors several times and changed its owners four times. For example, after the Jiangdu mutiny, Yu Wenhua and the killing of Emperor Yang of Sui appointed Su Wei as the doctor of Guanglu; Later, Yu Wenhua was defeated by the Wagang army, and Su Wei was attached to Li Mi's Wagang army; After the defeat of the Wagang Army, Su Wei switched to Wang Shichong again. It can be seen that Su Wei is a typical political tumbler and an evergreen tree in officialdom.

However, what Li Shimin hates the most is this kind of tumbler and evergreen, to put it mildly, this kind of person is the grass on the wall, falling with the wind. The problem is that Su Wei feels that he is old, has stood tall for three dynasties, and is now in his eighties, and hopes to continue to be reused in the Tang Dynasty.

Therefore, when Su Wei met Li Shimin, he deliberately put up a score, probably to despise Li Shimin's youth, and also to test whether Li Shimin was a corporal of courtesy. After seeing Li Shimin, Su Wei was very arrogant, claiming that he was old and sick and could not bow down.

never expected that Li Shimin would not eat him at all, and when he saw Su Wei like this, he was immediately very unhappy and despised him very much. Li Shimin understands that if he agrees to Su Wei's request today, it is equivalent to being eaten by him, and he will make more unreasonable demands in the future. Therefore, this time, Li Shimin must not compromise, and his attitude must be tough. So, Li Shimin sent someone to hold Su Wei accountable, and said in a sarcastic tone:

The prime minister of the public Sui room could not be helped in danger, so that the monarch killed the country. See Li Mi and Wang Shichong all bowing and dancing. Now I am old and sick, and I have no work to see each other. (Information Governance Guide)

Su Wei would never have thought that Li Shimin, a young man in his twenties, would be so assertive. Su Wei originally wanted to rely on the old man and sell the old and shake his majesty, but he didn't expect to plant a big heel, which is not easy for Li Shimin. After the Tang army returned to Chang'an, Su Wei proposed to meet Tang Gaozu again, but he was rejected again, and he ate a closed door, and no one cared about it from then on.

Why did Tang Gaozu refuse to see Su Wei? The reason is simple. At this time, the Tang Dynasty had already entered the Central Plains and was unstoppable in dominating the world. Therefore, the Li Tang Dynasty needed to set a moral benchmark in front of the people of the world: loyalty, filial piety, benevolence and righteousness. Obviously, a tumbler like Su Wei is far from meeting the moral standards of loyalty, filial piety, benevolence and righteousness. Even if Su Wei went through three dynasties and was highly respected, Tang Gaozu did not intend to continue to reuse him.

Soon after, Su Wei died at home. Due to Su Wei's old age and illness, and he had no financial resources, his life was difficult, and he had not yet recovered his official title. Therefore, it is equivalent to saying that Su Wei died in poverty and disease, at the age of eighty-two, which is also the end of his life.

After entering Luoyang, Li Shimin took advantage of his leisure time to visit the palace buildings left over from the former Sui Dynasty. As we all know, Emperor Yang of the Sui Dynasty spent a lot of manpower, material and financial resources to build Luoyang into the first international metropolis in eastern China in order to build Luoyang, the eastern capital. Therefore, the palaces and palaces in Luoyang City are also magnificent, beautiful, and extremely luxurious.

When Li Shimin saw these luxurious palace complexes, he recalled the past of the fall of the Sui Dynasty, and couldn't help but sigh: "Extravagance, poor people's desires, no death!" "No wonder the Sui Dynasty will die, so many and gorgeous palaces, I don't know how many people have been looted. If a country does not know how to cherish its people, it is destined not to last long. "Extravagance, poor people's desires" is one of the reasons why Emperor Yang of Sui died and the country was destroyed.

In order to remember the lessons of the rapid demise of the Sui Dynasty, and also to prevent the signs of corruption and degeneration and greed for pleasure within the Tang army, Li Shimin ordered the demolition of the Duanmen Tower, the burning of the Qianyang Palace, and the destruction of many luxurious and extravagant palaces and gatehouses. At the same time, many of the monasteries in Luoyang City were abolished, and thirty monks and nuns were dismissed on the spot, so that all of them returned to their original residences:

King Shimin of Qin looked at the Sui palace and sighed: "Extravagant, poor people's desires, no death!" "Ordered to remove the gate tower, burn the Qianyang Palace, and destroy the gate of heaven and que; The dojos were abolished, the monks and nuns in the city, and there were thirty famous and virtuous people left, and the rest returned to the beginning. (Information Governance Guide)

It can be seen that from this time, Li Shimin began to explore the reasons for the fall of the Sui Dynasty, and why the Sui Dynasty went from unprecedented prosperity to collapse in an instant. In fact, after Li Shimin became emperor, he often used the negative example of Emperor Yang of Sui to spur and alert himself. It is precisely because of such a strong sense of distress that Li Shimin, Taizong of the Tang Dynasty, was able to exert himself and be diligent, create the famous "Zhenguan Rule" and become an emperor of the ages.

To be precise, as of this time, Li Shimin has basically stabilized the situation in Luoyang, so that after Wang Shichong led the people to surrender, Luoyang has developed in a good direction in all aspects. However, this does not mean that Li Shimin can sit back and relax completely. Because, Li Shimin still has one last important thing, which is also the last step of the Li Tang Dynasty to unify the Central Plains: to conquer the Hebei states and pacify the old territory of the Xia Kingdom.

Although, through the Battle of Tiger Pass, Li Shimin broke the main force of more than 100,000 Xia troops and captured Dou Jiande, the king of Xia. However, after all, the foundation of the Xia State is still there, and Hebei is still under the control of the Xia State. Although at this moment, all the main forces of the Xia army have been wiped out in the battle of Tiger Pass. However, Xia Guo still had the strength to fight a battle, and he fought against Li Tang and fought a last-ditch battle, but it did not reach the point of being embattled.

Only by completely taking Hebei, unifying the Central Plains of the Tang Dynasty, and breaking the ultimate strategic goal of Zheng and Xia can it be regarded as a successful end. Therefore, what Li Shimin had to do next was to conquer the Hebei Prefectures in one fell swoop and complete the last step of the Li Tang Dynasty's Dingding Central Plains.

By this time, the situation was quite favorable for the Tang Dynasty. Dou Jiande's army was defeated and captured, and the main force of the Xia army was lost, resulting in the leaders of the Hebei group of dragons and panic. Therefore, at this time, strike while the iron is hot and strengthen the political offensive, and the Hebei prefectures will be able to spread the word and look at the wind.

Sure enough, on May 15 of the fourth year of Wude (621), Dou Jiande's old left servant shot all the good deeds, and surrendered to Li Tang with the land of the three states of Wei, Xiang and Wei. At the beginning, in the battle of Tiger Pass, the Xia army was defeated like a mountain, Dou Jiande was captured, and there was chaos on the battlefield. Therefore, taking advantage of the chaos, Qi Shanxing escorted Dou Jiande's wife Cao Shi, led hundreds of cavalry, fled to Zhaozhou, and returned to Hebei.

Qi Shanxing's surrender to the Tang Dynasty with the land of three states was undoubtedly a good start for the Tang Dynasty to conquer the Hebei states. After the Battle of Tiger Pass, many remnants of the Xia army retreated to Zhaozhou one after another. At this time, Dou Jiande had become a prisoner of the Tang army, and the remnants of the Xia army, which had no leader, suddenly fluctuated in people's hearts, and seemed to have lost their backbone, and they didn't know where to go next, whether to continue to occupy Hebei to fight against the Tang army, or to adapt to the situation and surrender to the Tang Dynasty.

At this moment, within the Xia Kingdom, opinions are very discordant, and there is a serious division. Some people believe that since King Xia was captured, the country should not be left without an owner for a day, and Dou Jiande's adopted son should be supported as the new monarch. Then a large number of troops were recruited on the spot to replenish the new force, and if Li Shimin led the army to attack, he would fight to the death with the Tang army.

However, some people's thoughts are very negative. They believed that Xia Guoqi was exhausted, so it was better to disperse, and simply do nothing, loot the local residents, property, and materials in Hebei, and then go into the sea to become pirates, leaving nothing for the Tang army.

One side advocated supporting the new monarch and confronting Li Tang; On the other hand, it advocated abandoning Hebei and occupying the island as a thief. Qi Shanxing resolutely opposed the opinions of the two parties, and he was not only opposed to continuing to fight against the Tang army, but also opposed to plundering the people into the sea. So, Qi Shanxing patiently analyzed the situation for everyone:

At the end of the Sui Dynasty, there was chaos, so I gathered in the grass and wilderness to survive. With the heroic martial arts of the Xia King, pacifying Heshuo, the horses are strong, once captured, it is as easy as a snap, is it not the destiny of heaven, and it is not human power to fight for evil! Now that we are defeated like this, we will not succeed in defending it, and it is inevitable to escape, so how can we restore the poison to the people if we are ruined by the country! If you don't commit yourself to the Tang Dynasty, those who want to get silk should scatter all the things in the treasury, and don't restore the crippled people! (Information Governance Guide)

Qi Shanxing analyzed that the current situation is irreversible. Think about it, King Xia is so wise and martial, he has been on the road for several years, pacifying Hebei, and his soldiers are strong. However, once the army is defeated and captured, it is not like a flood that discharges the embankment, and it is difficult to change the defeat. Therefore, whether it is to defend Hebei or flee in groups, it is inevitable that the fate of the country will be lost in the end. Therefore, the only way out is to surrender to the Tang Dynasty.

In addition, in response to the abduction of the people proposed by some people, Qi Shanxing is also extremely disapproves. In his opinion, even if he really surrenders, he cannot harm the people at the last moment, which will only arouse public anger and ruin his reputation. Moreover, Qi Shanxing proposed a method, don't you just want to ask for more property, it is better to open the treasury, take as much as you want, and don't rob the people.

In the end, after Qi Shanxing's patient persuasion, everyone finally unified their thoughts and agreed to descend to Tang. Immediately afterwards, Qi Shanxing ordered people to open the treasury, take out all the hundreds of thousands of gold silk property stored in it, and put them on the East Street of Wanchun Palace, so that the soldiers could pick them up. At the same time, Qi Shanxing sent troops to guard all alleys and streets, stipulating that once they were finished, they would leave immediately and not enter the people's homes again. In this way, hundreds of thousands of pieces of gold silk took three days and three nights to completely divide them.

After dividing the property, the soldiers and soldiers of Xia all got a generous "scattering fee", and they were satisfied, so they dispersed. In this way, the remnants of the Xia army that survived the Battle of Tiger Prison Pass were dismissed on the spot in such a peaceful way. Next, Qi Shanxing will officially dedicate his land to the Tang Dynasty.

Soon, Qi Shanxing and his right servant shot Pei Ju and Xingtai Cao Dan, led the civil and military officials of the Xia State, Feng Dou Jiande's wife Cao Shi and the eight seals of the country, as well as all the treasures obtained in time from the previous elimination of Yu culture, to ask the Tang Dynasty to surrender. Tang Gaozu Li Yuan felt that Qi Shanxing was a person who could recognize the situation and take the initiative to surrender to the Tang Dynasty, and he was very measured in handling things. Therefore, Tang Gaozu continued to entrust Qi Shanxing with important responsibilities, appointed him as the second protector of the left of the King of Qin, served under Li Shimin, and rewarded him.

Qi Shanxing dedicated his land to the Tang Dynasty, marking the complete annexation of the Hebei region to Li Tang, and the Tang army conquered the entire territory of Hebei in one fell swoop without spending a single soldier, disintegrating the foundation of the Xia State's political power. The Li Tang Dynasty entered the Central Plains and broke the last step of Zheng and Xia was successfully realized, and it was completely completed!

As the so-called double happiness came to the door, not long after Hebei returned to the Tang Dynasty, good things came to the Tang Dynasty again. On May 21, the fourth year of Wude (621), Wang Shichong's Xuzhou Xingtai and Qi Wang Shibi surrendered to the Tang Dynasty with 38 states such as Xu and Song. At this point, all of Wang Shichong's territories, cities, prefectures and counties in Henan were all included in Li Tang's rule, and the Henan region was finally pacified.

After Li Shimin broke the main force of the Xia army and captured Luoyang, the officers and men of the Tang army struck while the iron was hot, and in less than a month, they quickly subdued all the areas of Henan and Hebei, realized the strategic plan of the Tang Dynasty to unify the Central Plains, and won the final victory of the eastward expedition to Luoyang.

No matter from which aspect, the capture of Luoyang and the pacification of the Central Plains were definitely a huge victory for the Li Tang Dynasty, which had only been founded for four years. The news of this victory spread to the four seas, and the whole country of Datang rejoiced, immersed in the joy of victory.

Especially the Tang Emperor Tang Gaozu Li Yuan was particularly excited. As early as shortly after the victory in the Battle of Tiger Pass, Tang Gaozu couldn't wait to write an edict to praise Li Shimin and the soldiers of the Tang Army, and sent Shangshu Zuo Servant Pei Lin as a special envoy to Luoyang to comfort the three armies:

The Sui clan fell apart, and Cuihan was isolated. The two males are combined, and they are clear. The soldiers were not only victorious, but also had no casualties. He is worthy of being a minister, not worried about his father, and you are also meritorious. ("Old Tang Dynasty Book: Taizong Benji")

From July of the third year of Wude (620), the Tang army officially went east to Luoyang, and in May of the fourth year of Wude (621), Wang Shichong led the people to surrender, and the whole territory of Hebei was attached to Li Tang. Li Shimin led 100,000 soldiers of the Tang Army, and after ten months of hard fighting, finally wiped out the Zheng regime of Wang Shichong in Henan and the Xia regime of Dou Jiande in Hebei, the two largest military groups in the Central Plains.

Since then, the Central Plains and Hebei areas have basically been owned by Li Tang. After this battle, the Tang Dynasty completely controlled the Yellow River Valley, and its sphere of influence included almost half of China. The Tang Dynasty's grand cause of dominating the world has made breakthrough progress and leaps.

The battle of the Eastern Expedition to Luoyang and the destruction of Zheng and Xia was a key battle in the unification war of the early Tang Dynasty, and it was also an extremely important war. The victory in the Battle of Luoyang was of great significance to the unification of the Li Tang Dynasty. To sum up, there are two main far-reaching impacts.

First, the strategic plan of the Tang Dynasty to enter the Central Plains was successfully completed.

At the beginning of the founding of the Tang Dynasty, in order to unify the world and sweep away the heroes, Tang Gaozu Li Yuan formulated the general policy of unification war: consolidating Guanzhong, conquering the Central Plains in the east, and leveling the south of the Yangtze River. Therefore, through a series of military operations, the Tang Dynasty successively eliminated the Xue clan in Longxi, Li Liang in Hexi, Liu Wuzhou in Shanxi and other separatist forces, consolidated the military posture in the Guanzhong region, and relieved the worries of Li Tang's army to march eastward and point at the Central Plains.

After the situation in Guanzhong was completely stabilized, the Tang Dynasty immediately marched into the Central Plains. Therefore, Li Shimin personally led 100,000 Tang troops to the east to conquer Luoyang, and after ten months of bloody battles, he finally defeated Wang Shichong and Dou Jiande, captured Luoyang, swept Henan and Hebei, and realized the unification of the Central Plains. Therefore, the complete victory of the Battle of Luoyang marked the entry of the Li Tang Dynasty into the Central Plains and the completion of the second stage of the strategic planning in the great cause of unification.

Second, it basically laid the pattern of Datang dominating the world.

To be precise, the eastward expedition to the Central Plains was a key move in the great cause of reunification of the Tang Dynasty. After this battle, the trend of Datang dominating the world was basically decided. In fact, before the Tang Army's Eastern Crusade, Wang Shichong and Dou Jiande were both powerful separatists in the world, and they were the most qualified to compete with the Tang Dynasty for the lord of the world. However, in the final result, Wang Shichong and Dou Jiande were defeated by the Tang Dynasty one after another, and both went offline and became prisoners of the Li Tang Dynasty.

gnawed the two hard bones of Wang Shichong and Dou Jiande, which was a huge victory for the Tang Dynasty. The complete victory of the Eastern Crusade basically laid the pattern of the Tang Dynasty's domination of the world. From then on, the road to the Tang Dynasty's domination of the world will be a flat river; There is no longer any separatist force that can stop the Jin Ge Iron Horse of the Li Tang Dynasty. In less than ten years, the Tang Dynasty established by the Li family and his son will surely pacify the four seas and end the turbulent times in the late Sui and early Tang dynasties!

In this world-renowned battle of Luoyang and Tiger Prison Pass, Li Shimin brought his wisdom, bravery, composure, courage and other commanding talents to the extreme. At the beginning, Dou Jiande personally led more than 100,000 Xia troops to aid Luoyang; And Li Shimin only led 3,500 Xuanjia troops to seize the Tiger Prison Pass and intercept Dou Jiande's army. As a result, Li Shimin defeated Dou Jiande's more than 100,000 soldiers and horses with only 3,500 Xuanjia troops, created an immortal miracle of war, and won a decisive victory in conquering Luoyang and destroying Zheng and Xia.

After the founding of the Tang Dynasty, the heroes competed with each other, and the separatist forces that took advantage of the situation in various places were eyeing the Tang Dynasty. As an outstanding military commander, the young Qin King Li Shimin worked tirelessly, continuously led the troops to the battle, led the Tang army soldiers to conquer the south and the north, and pacified the crowds, and determined the Quartet with divine force.

From the beginning of the founding of the Tang Dynasty, Li Shimin has been galloping on various battlefields, Pinglongxi, Dinghedong, Luoyang, and Zhanhujiao, and successively defeated Xue Rengao, Liu Wuzhou, Song Jingang, Dou Jiande, Wang Shichong and other strong opponents.

It can be said that Li Shimin fought for the Tang Dynasty in the south and the north, opened up the territory, annexed one separatist regime after another for the Tang Dynasty, and created an invincible and invincible war myth on the battlefield with his outstanding military talent and unbridled commander's charm.

It is no exaggeration to say that the establishment and unification of the Tang Dynasty are mostly due to Li Shimin. Li Shimin relied on his outstanding military exploits to lay down half of the Tang Dynasty. It can even be said that if there is no Li Shimin in the Tang Dynasty, it will never pacify the four seas and dominate the world within ten years.

Since then, Li Shimin's prestige has soared day by day, and he has gradually become an indispensable figure in the core of Tang Dynasty power. Especially when Li Shimin conquered Luoyang and returned to the dynasty, he and the soldiers of the Tang Dynasty were ceremoniously welcomed by the soldiers and civilians of Chang'an, and the scenery was infinite for a while.

On the ninth day of the seventh month of the fourth year of Wude (621), Li Shimin led an army of 100,000 to the east, returned triumphantly, and returned to Chang'an in a mighty manner, just as he was solemn and grand when he led the army to the expedition. This iron-blooded army, which had fought for ten months, finally made immortal achievements under the leadership of their commander Li Shimin, the king of Qin, and returned to Chang'an, the capital of the Tang Dynasty.

Li Shimin led the Tang army, the class returned to the dynasty, and the soldiers and civilians in Chang'an City held a grand welcome ceremony. The entire ceremony of the Tang army's entry into the city and the dedication of victory was an unprecedented grand occasion since the founding of the Tang Dynasty, which was unprecedented. The grand occasion at that time is clearly recorded in the history books:

Taizong personally wore gold armor, 10,000 iron horses, 30,000 armor soldiers, and preached in the front and rear, capturing the two false masters and Sui's utensils and offering them to the Taimiao. The great joy of the ancestors, drink to the courtesy to enjoy. Gaozu is not a special official since ancient times, but a different emblem, with virtue. ("Old Tang Dynasty Book: Taizong Benji")

Li Shimin, the king of Qin, led 100,000 Tang troops, returned from the Eastern Expedition, and triumphantly marched to Chang'an. I saw that Li Shimin was wearing golden armor, leading 10,000 iron horsemen and 30,000 armor soldiers to enter Chang'an City. After entering the city, Li Shimin dedicated the captured Zheng Emperor Shichong, Xia King Dou Jiande, as well as the utensils and chariots of the Sui Dynasty to the Taimiao.

At that time, it was the height of summer, the sun was shining, and the dazzling sunlight shone on Li Shimin's golden armor, shining with golden light. Moreover, when Li Shimin led the army into the city, the formation was very spectacular, the front and rear military music was drumming, followed by 25 generals such as Li Yuanji and Li Shiyun, the king of Qi, which was really majestic.

So, how to commend Li Shimin's immortal exploits in conquering Luoyang? Since the establishment of the Tang Dynasty, Li Shimin has been fighting everywhere and has repeatedly performed miraculous feats. Long before the eastward expedition to Luoyang, Li Shimin successively commanded the pacification of the Western Qin Xue regime and the defeat of Liu Wuzhou and Song Jingang.

With the outstanding military exploits made on the battlefield every time, Li Shimin's political status in the Tang Dynasty court is also gradually rising. Therefore, before leading his army to Luoyang, Li Shimin had already held several important military and political positions. At this time, Li Shimin had several political identities: King Qin, Shang Shuling, General Youwuhou, Yongzhou Mu, Taiwei, Shaanxi East Dao Xingtai Shangshuling, Zuo Wuhou General, Liangzhou Governor, Yizhou Dao Xingtai Shangshuling.

Because Li Shimin held many important military and political positions, he was in charge of the military command of the Tang Dynasty, and he made immortal achievements in the capture of Luoyang. Therefore, Tang Gaozu Li Yuan no longer knows what kind of official position should be awarded to this second son? After thinking about it, Li Yuan believes that the old official titles in ancient times are no longer enough to highlight Li Shimin's world-famous achievements. So, Tang Gaozu Li Yuan decided to create an unprecedented title to commend Li Shimin's merits.

In the tenth lunar month of the fourth year of Wude (621), Tang Gaozu gave Li Shimin the title of "Admiral of Tiance", which was an unprecedented title that had never been given before. It is equivalent to saying that the title of "General Tiance" marks that Li Shimin has officially become the veritable supreme military commander of the Tang Dynasty.

At the same time, Tang Gaozu Li Yuan asked Li Shimin to lead Situ (one of the three dukes) and Daxingtai of Shaanxi East Road, located on the prince, and the number of food towns increased to 30,000, opened the Tiance Mansion, set up an official office, and placed the Luoyang area under the jurisdiction of Li Shimin. It can be said that Li Shimin at this time, in the early years of Tang Gaozu Wude, reached the peak of his life and career:

In October, the plus general Tiance, the Daxingtai of Shaanxi East Road, was located on the prince. 20,000 households were added, and 30,000 households were passed. Give a gold chariot, a crown of clothes, a pair of jade, 6,000 catties of gold, the front and back of the preaching and the music of the nine parts, and 40 swords. ("Old Tang Dynasty Book: Taizong Benji")

It is particularly worth mentioning that after the capture of Luoyang, Li Shimin ushered in the peak moment of his life and career. At that time, if it was a matter of dominance, no one could compare with Li Shimin.

First of all, Li Shimin has an important political identity - "General Tiance", who is on the throne of the prince. The plus name "General Tiance" means that Li Shimin has become the supreme military commander of the national army in the Tang Dynasty, holding the guns of the national army.

In addition, in addition to the "Tiance General", Li Shimin also has two crucial identities: Daxingtai of Shaanxi East Road and Daxingtai of Yizhou Road. Daxingtai in eastern Shaanxi means that the Central Plains around Luoyang are under the jurisdiction of Li Shimin; Yizhou Dao Daxingtai means that the country of Sichuan Tianfu is also under his jurisdiction. If you go east, you can go to Luoyang, and if you retreat to the southwest, you can retreat to Sichuan, and you can attack and defend. In other words, Luoyang and Sichuan have become Li Shimin's sphere of influence and his strong political capital.

From the army in Jinyang to the entry into the Guanzhong, and then to personally command the unification war in the early Tang Dynasty, sweeping away the separatism. During this period, Li Shimin, the king of Qin in his early twenties, became a high-profile figure in the political and military circles of the Tang Dynasty.

In the past few years, Li Shimin relied on the southern and northern wars, countless military achievements, and won half of the Tang Dynasty's charming achievements, and was named an unprecedented "Tiance General" by his father Tang Gaozu Li Yuan, who was above the prince and became the deservedly supreme military leader of the Tang Empire, second only to Tang Gaozu Li Yuan and the crown prince Li Jiancheng. At this moment, Li Shimin has reached the pinnacle of his life and career and has become a key figure in the Tang Dynasty.

However, as Li Shimin reached the pinnacle of his life and career, the power in his hands became greater and greater. A potential threat, but quietly emerging. The power struggle within the Li Tang royal family gradually began to ferment. Li Shimin's achievements are unparalleled in the world, threatening the crown prince Li Jiancheng's status as a prince. At the same time, due to his own world-famous exploits and the increasing power in his hands, Li Shimin's desire for the throne was further stimulated. Therefore, from this time on, Li Shimin coveted the position of the crown prince of his eldest brother Li Jiancheng, and his ambition to swallow the sky was gradually revealed.

Therefore, after the Battle of Luoyang, the relationship between Li Shimin and his eldest brother, the crown prince Li Jiancheng, began to drift apart. This pair of siblings, brothers who were once close and fought side by side, finally came to the point of meeting each other in arms and fighting in the same room; Li Shimin finally embarked on a road of killing his brother and slaughtering his brother and seizing power from the palace gate, which directly triggered the "Xuanwumen Change". Of course, that's all for later.

In any case, in May of the fourth year of Wude (621), the much-anticipated Battle of Luoyang finally came to an end with the complete victory of the Li Tang Dynasty. After ten months of bloody battles, the Tang army, under the leadership of Li Shimin, finally conquered Luoyang, entered the Central Plains, successfully completed the Eastern Crusade, and achieved the key victory of the Tang Dynasty to unify the world. Since then, the Tang Dynasty's domination of the world has basically become an indisputable fact.

However, conquering Luoyang and entering the Central Plains does not mean that the Tang Dynasty will be able to sit back and enjoy its success from now on. On the contrary, there is still a long way to go before we can completely dominate the world. Realizing the unification of the Central Plains was only a crucial part of the unification strategy for the Li Tang Dynasty, but it did not complete the overall strategy of the Tang Dynasty to unify the world. How to consolidate the fruits of this hard-won victory is also a problem that cannot be ignored, whether it is for Tang Gaozu Li Yuan or for the entire Tang Dynasty.

However, before the Tang Dynasty monarchs and ministers could toast to celebrate the great victory of the Eastern Expedition to the Central Plains, at the end of December of the same year. That is, in December of the fourth year of Wude (621), an eight-hundred-mile urgent war report from Hebei was sent to the Taiji Palace in Chang'an by a fast horse, and placed in front of the imperial case of Li Yuan, the ancestor of the Tang Dynasty; When Li Yuan opened this battle report, the ruler of the Tang Empire, his face became more and more solemn: Liu Heimin, the old department of Dou Jiande, conquered the old capital of the Xia Kingdom, and all parts of Hebei responded one after another, and the forces of the rebels were all in Dou Jiande's old realm.

It has been less than half a year since the capture of Luoyang, and the whole territory of Hebei has rekindled the flames of war; What Li Yuan didn't expect was that this sudden Hebei rebellion made the Tang Dynasty helpless for a while, and countless founding fathers were sunk in the sand, and they were forever frozen on the land of Yanzhao.

So, why did a rebellion suddenly break out in the land of Hebei, which had just been pacified? Why did the rebel forces get a response from Dou Jiande's old ministry and quickly swept through the old realm of the Xia Kingdom? In the face of this massive Hebei rebellion, how will Tang Gaozu Li Yuan, as the supreme ruler of the Tang Dynasty, respond? And in this counterinsurgency war that is different from the past, Li Shimin, the king of Qin, who has been invincible and conquers everything, and has conquered half of the Tang Dynasty, what valuable lessons have he learned from it, and what kind of benefits will this have for him to create the "rule of Zhenguan" in the future?
