In 201 BC, Liu Bang personally led an army of 300,000 to attack the Xiongnu in the north, but Liu Bang himself would not have imagined that in this battle he encountered a terrible opponent since Xiang Yu: Mao Dun Shan Yu, the first person in the history of the nomadic people to unify the various departments of the steppe.
At that time, most of Liu Bang's troops were infantry, and Liu Bang, who was eager to fight, was eager to find the main force of the Xiongnu to fight a decisive battle, and was confused by the "illusion" of Mao Dun Shan Yu, Liu Bang's forward troops led thousands of troops to enter directly, but this was exactly in the arms of Mo Dun Shan Yu, and 400,000 troops surrounded Liu Bang's thousands of regiments, and finally trapped in a place called Bai Deng Mountain.
Here Liu Bang was trapped for seven days and seven nights, until the strategist Chen Ping offered advice and bribed The Fu clan of Mo Dun Shan Yu, and finally Mo Dun Shan Yu agreed to Liu Bang's request and let Liu Bang leave, it is said that when Liu Bang fled, he could be said to be fast and whipped, and did not dare to look at both sides at all.
Since then, Liu Bang and the Xiongnu have set up a policy of "peace and affinity". For the next seventy years or so, the Han Dynasty continued to follow the "peace and affinity", until the Han Wudi Emperor Liu Che succeeded to the throne, and thus changed this decision, and the Han and Hungarian sides changed their form from then on.
How many questions do we have in the face of the "Siege of Bai Deng"? Why did the Xiongnu retreat under the preponderance of the Xiongnu? At that time, Han Xin was still there, why did Han Xin not lead the army, and if Han Xin went to war, would it change the pattern of the battlefield and let the Han army win?
Why did Mao Dun shan Yu let Liu Bang leave?
In fact, many people at that time for The Idea of Mo Dun Shan Yu was also very incomprehensible, at that time Mo Dun Shan Yu Obviously occupied the initiative position, but did not launch an attack, let Liu Bang leave, if at that time Mo Dun Shan Yu was a little bolder, then the history of the Han Dynasty would be rewritten, but if you really consider the overall situation from that time, you will find that Mo Dun Shan Yu also had to do it:
First of all, At the time of the Chu-Han War, Mao Dundan unified the entire grassland, broke through the Eastern Hu and defeated the Yue clan in the west, so that the originally weak Xiongnu gradually became stronger. However, Mo Dun Shan Yu did all this on the basis of the confrontation of power, Mo Dun Shan conquered the steppe departments by force, but it also led to a serious loss of national strength, domestic complaints, and at that time the countries in the western region also did not obey the control of Mo Dun Shan Yu, in order to maintain the needs of rule, Mo Dun Shan Yu must first start to solve the internal problem, once he killed Liu Bang, Mo Dun Shan Yu would face a situation of two-front combat.
Secondly, at that time, Mao Dundan was all cavalry, and although Liu Bang's troops were infantry, baideng mountain was easy to defend and difficult to attack, and this was exactly what Liu Bang's troops were good at. Before this, Mao Dun Shan Yu also attacked several times, but first, the Xiongnu army was not good at attacking the city, and second, it did not have heavy weapons to attack the stronghold, and the large army of the Han Dynasty was also coming, and continuing to drag on was extremely unfavorable to Liu Bang, and it was equally unfavorable to Mo Dun Shan Yu.
Third, it is that Mao Dun Shan Yu did not really want to start a war with the Han Dynasty, and unifying the grasslands with the strength of the Xiongnu was already its limit, and the national strength of the Han Dynasty was far above that of the Xiongnu, and with the Xiongnu at that time, mao Dun Shan did not intend to start an all-out war with the Han Dynasty at the beginning, but only got some money from the Han Dynasty.
Therefore, this is also why Mao Dun Shan Yu Ming, in the case of having the advantage, still let Liu Bang leave. Then some people asked, if Han Xin was there at that time, would it change Liu Bang's fate?
Why didn't Han Xin save Liu Bang?
At the time when Liu Bang was trapped on Mount Baishan, Han Xin was still there, and if Han Xin's military means were used to face Mo Dun Shan Yu naturally, but Liu Bang did not take him with him, why didn't Han Xin go to the rescue of Liu Bang?
First of all, Liu Bang's means of cutting off the gong after pacifying the world had already made Han Xin chill, and baideng's siege was Liu Bang's suspicion of another foreign-surnamed wang at that time, Han Wangxin, who only surrendered to the Xiongnu and the Xiongnu against Liu Bang, so it also caused Liu Bang to march against the north.
And Han Xin's situation was also extremely difficult at that time, so in this case, even if Liu Bang was under siege, han Xin's disposition would never go to the rescue, and even if he wanted to rescue, he would threaten Liu Bang like the "False King of Qi" incident that year.
Secondly, Han Xin's situation at that time was not good, in 201 BC, Xiang Yu's former general Zhong Liyi defected to Han Xin, liu Bang knew, thunder was angry, ordered Han Xin to arrest Zhong Lixiao, and at that time, someone advised Han Xin to either kill Zhong Liyi or rebel, Han Xin chose the former, and Zhong Liyi was forced to commit suicide.
However, when Han Xin handed over Zhong Liyi's first rank to Liu Bang, Liu Bang did not dispel his suspicions about Han Xin, and although he pardoned Han Xin for his sins, he put him under house arrest in Luoyang and renamed him "Marquis of Huaiyin", that is to say, at that time, Han Xin did not even have personal freedom, how could he control the military power?
Therefore, this is also why Liu Bang, the "Siege of Baideng", was able to escape from death, but Han Xin did not rescue him, and after the Siege of Baideng, Han Xin, the Marquis of Huaiyin, eventually died, and a generation of military gods fell.
