On March 10, 618, Yu Wenhua and led the "Xiaoguo Army" to rebel, invaded Yangzhou, and strangled the Sui Emperor Yang Guang, known in history as the "Change of Jiangdu". After that, the world flocked to the throne, and Li Yuan declared himself emperor in Chang'an and established the Tang Dynasty. Li Mi, Wang Shichong, Dou Jiande, Yu Wenhua and each of them are kings. Later, Li Mi was defeated by Wang Shichong at Luoyang, and Yu Wenhua was killed by Dou Jiande. The people who really have the ability to chase after the Central Plains are Li Yuan (Tang), Wang Shichong (Zheng), and Dou Jiande (Xia).
In the third year of Wu De (620), Li Yuan issued an edict and ordered Li Shimin, the King of Qin, to lead a large army to conquer Wang Shichong, and Li Shimin led Li Ji, Qin Shubao, Cheng Zhijie, Duan Zhixuan, Wei Chigong and others to march all the way, and the Tang army was unstoppable, and continuously conquered more than fifty prefectures and counties in Henan, directly approaching Luoyang. Wang Shichong was stunned and rushed to Dou Jiande for help. Dou Jiande and Wang Shichong also had a vendetta and were reluctant to send troops.
But at this time, Dou Jiande's adviser Liu Bin advised:
"The world is in chaos, Tang de Guanxi, Zheng De Henan, Xia De Hebei, a total of the momentum of the full." Now that Tang Dynasty is raising troops to Zheng and Zheng is dead, Xia cannot be independent. It is better to send troops to save it, and the soldiers of the two countries, riding on the old age of the Tang Division, the world is also desirable! (Excerpt from "Zizhi Tongjian", with deletions)
I have to say that Liu Bin's words are still very reasonable, Dou Jiande, as a temporary tyrant, can not know the truth of "cold lips and dead teeth". As a result, Dou Jiande sent troops to rescue Wang Shichong, and the "Battle of Tiger Prison Pass" broke out.
When Li Shimin heard that Dou Jiande had come to his aid, on the one hand, he attacked Wang Shichong and besieged Wang Shichong in the city of Luoyang, and on the other hand, he organized troops to block Dou Jiande, and as a result, Li Shimin blocked Dou Jiande's 100,000 troops with 3,500 Xuanjia troops. In this way, Li Shimin trapped Wang and Dou at the same time.
In this great battle, Li Shimin's wisdom, bravery, endurance and decisiveness were brought to the extreme, and finally Wang Shichong surrendered, and Dou Jiande was captured.
After this battle, the Tang army unified northern China, the world was strong, and it was no longer able to compete with the Tang army, so Li Shimin, the king of Qin, was also crowned as a general of Tiance, and the Qin royal palace also collected many talents, laying the foundation for the future changes in Xuanwumen.
In fact, the reason why so many civilian and military generals were willing to submit to Li Shimin was not only because Li Shimin agreed to the war, but also because Li Shimin threw a "big stone" after the war.
Originally, after Li Shimin defeated Wang Shichong and invaded Luoyang City, on the one hand, he sent troops to maintain order in the city, "entering Luoyang first, guarding the city, prohibiting plunder, and no one dared to commit crimes." On the other hand, Li Shimin urgently ordered Fang Xuanling and Du Ruyi to collect the maps, household registrations, letters left by Wang Shichong, as well as the Sui Dynasty edict (Luoyang was originally the capital of Sui).
According to Liu Zongyuan's "Dragon City Record":
Emperor Taizongwen of Pingwang Shichong, Yu Tu had a language of communication, and a number of documents were connected to hundreds of things. Emperor Taizong ordered Du to be obscure. If obscure fu is deceived, Emperor Taizong said: "Put it into cao officialdom." "It is heard that there are ministers who will commit suicide.
This means that when Fang Xuanling and Du Ruyi searched the books and literature, they found hundreds of secret letters, which were all evidence of collusion between the ministers and Wang Shichong. Li Shimin asked Du Ruyi to handle this matter, and Du Ruyi couldn't make up his mind, so he asked Li Shimin how to deal with it. Li Shimin replied: "It is enough to hand over to the relevant officials for normal handling (the investigation that should be investigated, the questioning that should be asked). "Soon, the news spread, and the minister wanted to commit suicide to escape the next punishment.
After Li Shimin heard about it, he solved this problem with a large stone. Dragon City Record Cloud:
The upper is to retrieve the document and wrap a thing on the back. Doubting the weight of the stone, the upper relatives wrapped in a hundred weights, the fate makes the Tuotuo River sink, and it is not provincial.
This means that When Li Shimin heard that someone was about to commit suicide, he hastily retrieved the letters, found a large stone, and ordered the letters to be wrapped and tied together with the stones. Li Shimin was afraid that the bundle would not be strong, so he personally wrapped many layers of cloth strips, and then ordered the stones and letters to be sunk into the Tuotuo River together. In this way, everyone was relieved.
At the end of the Eastern Han Dynasty, after the Guangwu Emperor Liu Xiu destroyed Wang Lang, he burned the letters exchanged between Wang Lang and officials in order to achieve the purpose of buying people's hearts. Li Shimin's imitation of Liu Xiu is actually buying people's hearts.
The author believes that before the Battle of Tiger Prison Pass, the world was undecided, people's minds were moving, and everyone wanted to leave a back road for themselves, so there were many people who stepped on two boats. Now that Li Shimin had destroyed Wang Shichong and Dou Jiande, and the north had returned to the Tang Dynasty, Li Shimin had destroyed his letters, allowing these people to be loyal to the Tang Dynasty without scruples, or to the Qin Dynasty. At the critical moment, Li Shimin threw a large stone into the river, and achieved the purpose of "fame and fortune", which can be described as clever.
