In the sixth year of the Han Dynasty, that is, in 201 BC, the Xiongnu, a powerful northern neighbor of the Han Empire, suddenly invaded south. Under the leadership of the leader Mao Dunshan Yu, the Xiongnu iron cavalry swept like a violent wind, making it difficult for Han Wangxin in the north to resist. In order to keep his position and wealth, Han Wangxin chose to surrender, and the entire Daijun fell to the hands of the Xiongnu. When the news reached the ears of Liu Bang, the ancestor of the Han Dynasty, he immediately mobilized more than 300,000 troops, gathered all the main forces of the Han army, and marched north with all his might. At this moment, the war between Han and Hungary is already on the verge of breaking out. Hearing that the Han army was pouring out, the cunning Xiongnu did not invest all their forces at first, but skillfully induced Han Wangxin to be the leader of the attack on the Han army. The regular army of the Xiongnu did not give much help, and only Han Wangxin, who played the role of a puppet army in this war, made Liu Bang feel a little troubled. However, by the seventh year of the Han Dynasty (200 BC), the Han army had basically uprooted Han Wangxin's forces and recovered all his homeland. When this land returned to the territory of the Han family, a trend of thought began to emerge within the Han army to seek a peaceful solution to the relationship with the Xiongnu. For the victory over the Xiongnu, although some Han generals showed bravery and skill in attacking Han Wangxin, they were still unsure in their hearts. At this time, they believed that a large-scale head-on clash with the Xiongnu should be avoided as much as possible, so as not to consume all the elite forces of the Han army in the first encounter. At this critical moment, Liu Jing stood up in Langzhong, and he reminded Liu Bang to be wary of the Huns' tactics to lure the enemy. However, Liu Bang did not listen to his advice, but angrily scolded Liu Jing: "You coward of Qi State!."You were originally promoted and made a fortune only with clever words, but now you want to shake the hearts of the army with your tongue!In a fit of rage, Liu Bang imprisoned Liu Jing in Guangwu Prison. 
Liu BangWe can't help but wonder that Liu Bang, as a veteran oilman, would not know the superficial tactics of luring the enemyIn terms of battlefield experience, although Liu Bang is not as good as Han Xin, he is still relatively sufficient. However, at the beginning of the campaign, Liu Bang's counterattack went too smoothly, causing him to have some thoughts of underestimating the enemy.
Han Wangxin was repeatedly broken by Liu Bang, and he could not support it, so he could only ask the new master, the Xiongnu, for backup. But even if the Xiongnu left and right Xian Wang came with 10,000 cavalry to help, they still could not resist the fierce offensive of the Han army. The Huns were defeated in Jinyang, defeated in the second and left the stone, and defeated in the third place, losing one after another, and fighting and retreating. In the confrontation on the plains, the Xiongnu nomadic cavalry turned out to be no match for the Han army's chariots.
Historical Records: The Biography of Han Xin Lu Wanlie contains: In the winter of the seventh year, he attacked from above, broke the bronze sword of the letter army, and beheaded his general Wang Xi. Believe in death and go to the Huns. He and the white native Manqiuchen, Wang Huang and others set up Zhao Li, a descendant of Zhao Miao, as the king, regained the letter and defeated the stragglers, and conspired with the letter and Mao Dun to attack the Han. The Xiongnu fought on the left and right, and the king of the virtuous king will ride more than 10,000 horses and Wang Huang and other tun to the south of Guangwu, to Jinyang, and the Han soldiers to fight, the Han Dynasty broke it, chased to the stone, and broke it again. The Xiongnu reunited the army to annoy the northwest, and the Han ordered the chariots to break the Xiongnu. The Xiongnu were often defeated, and the Han took advantage of the victory to chase the north.
After a brilliant victory, Liu Bang remained cautious. Before deciding to launch a decisive attack on the Xiongnu, he sent wave after wave of vanguard troops to penetrate deep into Xiongnu territory to detect the void and reality. These vanguard troops did not send only one team, but more than a dozen teams, and they all reported to Liu Bang: "The Xiongnu can be defeated!"”
Therefore, Liu Bang's anger did not stem from Liu Jing's analysis of the possible Xiongnu ambush, but because Liu Jing's views at this time were very likely to disturb the morale of the army.
When the main force of the Han army is assembled, if you don't dare to attack, will you have to turn around and flee when you see the Huns in the future?What's more, at this time, the Han army had successfully explored the location of the Xiongnu's lair, and Mao Dunshan Yu spent the cold winter there.
Suppose someone leads an elite cavalry unit to secretly advance northward, go straight to the Xiongnu's lair, and kill the Xiongnu Dashan Yu in one fell swoop, wouldn't it be possible to completely solve the northern problem of the Han court?Moreover, behind the cavalry troops, there were also 300,000 Han army main force foot soldiers, even if the front attack was blocked, the infantry army could quickly catch up and encircle, which was enough for the Huns to drink a pot.
If the reader is Liu Bang, what choice will you make in the face of such a situation?Do you choose to be safe, or do you take the risk of solving the northern problem in one fell swoop?This plan seems perfect, but there is a fatal flaw. That is Liu Bang. This supreme in the world actually took the lead, personally commanded the battle, and even served as the commander of the forward, which is not his usual style, but reminds people of Xiang Yu's style. Han Xin also bluntly said that Liu Bang was not good at leading troops. Moreover, everyone also knows that in the early days of this war, Liu Bang was besieged by the Huns on the top of Baishan Mountain, and almost all his troops were annihilated.
Historical Records: The Biography of Uncle Liu Jing and Sun Tonglie contains: "The King of Han believed in the rebellion, and Emperor Gao attacked him. To Jinyang, Wen Xin and the Xiongnu wanted to attack the Han together, and they were furious, so that people made the Xiongnu. The Huns hid their strong men and fat cattle and horses, but saw the old and weak and the livestock. The envoys came for ten generations, and they all said that the Huns could be attacked. The envoy Liu Jing returned to the Xiongnu and reported: "The two countries are fighting each other, and it is advisable to boast and see what is the director."
Today, the ministers are gone, and they see the barren old and weak, and they will want to see the short, and the Fu Qi soldiers will compete for profit. Foolishly thought that the Huns could not be attacked. At that time, the Han soldiers had already exceeded the sentence, and more than 300,000 soldiers had already been killed. was angry and scolded Liu Jing and said: "Qi Yu!."Winning the office with his tongue is now a vain speech to frustrate our army. "Respect Guangwu for the Department of Machinery. Then, to Pingcheng, the Huns made a surprise army to surround Emperor Bai Deng. ”
We can't help but ask, if the Battle of Baishan Mountain was a well-planned cavalry raid, then Liu Bang could have let the first cavalry general at that time, Yingyin Hou Guanying (Cao Shen was in Qidi at this time) lead the team. A few years ago, Guan Ying led the cavalry to raid the hinterland of Western Chu, and the results were very impressive. It doesn't matter if you go into battle in person, none of the generals who have survived a hundred battles have accompanied the army, and the most famous one who followed Liu Bang was a Wenchen - Chen Ping, a lieutenant in the army!On the other hand, Mao Dun's side is also very funny, this old man went out with his wife and a lot of family members. 
MaudunTherefore, the so-called Battle of Baideng may give it a second interpretation - it is not a raid and siege battle, but more like an epic dialogue between Liu Bang and Mao Dun. It was only during this dialogue that the two sides failed to reach an agreement, which led to the conflict. Otherwise, it is difficult for us to explain:1Why did Liu Bang personally lead the cavalry to Baishan Mountain and throw himself into the enemy's encirclement like a death?2.Why did Mao Dunshan Yu follow his wife's advice and let Liu Bang go just for a few pieces of gold, silver and jewelry when he wanted to eliminate Liu Bang in one fell swoop?After all, Maudon was a hero of the First Generation, and it would be impossible to say that he had no idea about the south. He could completely besiege Liu Bang on Baishan Mountain, and then wait for the Han army at the foot of the mountain, once the main force of the Han army was eliminated, he could go south directly, how difficult is this?Let's take a look at what kind of pillow wind is blowing by Maudun's wife. Emperor Gao then sent an envoy to secretly give a large amount of property to the Yan family. He then said to Maudun: "Two monarchs should not besiege each other. Nowadays, even if you get Han land, you alone will not be able to live there after all. And the King of Han also has gods, so you should think about it. Yan reminded Mao Dun: "The power of the Han court is very large, and it is by no means an opponent that can be easily defeated. Even if the Xiongnu went south, would they really be able to occupy the Han land?"Mao Dun's withdrawal is also very interesting, he did not directly remove the encirclement, but deliberately sold a flaw and let Liu Bang rush out with people. And I also found a reason in advance: it's not that I don't work hard, but Han Wangxin promised to send troops, but his people grinded foreign workers halfway. Mao Dun and Han Wang Xin's generals Wang Huang and Zhao Liqi, and Huang and Libing did not come, suspecting that they had a plot with Han, and also took the words of the Yan family, which was a corner of the siege. So Emperor Gao's edicts were all full of Fu Ya's foreign country, and they went straight out from the corner of the corner, and they joined the army, and Mao Dun led the troops away. "Maudun's excuse for withdrawing troops – with Han Wangxin's generals Wang Huang and Zhao Liqi, and Huang and Libing not coming – further confirmed that Baishan Mountain was not a war. At that time, Han Wangxin had been defeated in a mess, and this group of scattered soldiers, whether they came or not, had little impact on both Han and Hungary.
But this was the reason for Maudun's withdrawal, that is, Maudun itself did not want to continue fighting. When Liu Bang broke through, Mao Dun also pretended that I tried my best to block, but the Han army was too brave for me to resist. It's so difficult to release water, what's the purpose of Maoton?The answer is acting.
So, who is he playing for?Undoubtedly, the Xiongnu were not monolithic. Under the situation of the gradual unification of the steppe by the Xiongnu, the members of the internal ruling group expanded rapidly, but the contradictions and conflicts between them also increased. The concept of dignity and order was actually very weak among the Xiongnu. Everyone chooses to mix with you just because you are strong enough to lead everyone to make profits together. And when I go back to my tribe, I'm sorry, I'm the king here.
This also explains why it was not the main force of Mao Dun who fought against the Han army with Han Wangxin before, but the left and right Xian kings of the Xiongnu. In ancient and modern times, this kind of tactical thinking has been universal. This is called: defeat the enemy country to quell the external trouble, defeat the princes to quell the internal strife. The same is true of Liu Bang's strategy of placing Han Wangxin in Mayi and fighting with the Xiongnu. "
After Liu Bang returned to the camp, he did not call the army for **. On the contrary, both the Han and the Hungarians tacitly chose to retreat. In the Battle of Baishan, the Han and Hungarian sides gathered more than 500,000 troops (including troops fighting on the periphery). Seeing that the two empires of the north and the south were about to clash in an all-out way, they ended in thunder and rain. After Liu Bang returned to the camp, he released Liu Jing and sent him to conduct the first peace talks with the Xiongnu, officially starting the peace operation. 
In this regard, Liu Bang is very willing to spend a lot of money, because at first he planned to send his biological daughter Princess Lu Yuan to implement the strategy of harmony. In the next few decades, although the Xiongnu had a record of some troops going south, they did not launch a real large-scale southern invasion after all. As for the Han army, it lacked the motivation to go north, and focused on quelling the civil strife. In the Wenjing era after Liu Bang, no matter how much chaos occurred within the Han court, the Xiongnu never took any major action.
It was not until the time of Emperor Wu of the Han Dynasty that a new round of large-scale wars officially broke out. In this regard, I am afraid that there is only one explanation, that is, the Xiongnu actually lacked enough strength to capture the Han Dynasty. With a large territory in their hands, neither Han nor Hungary was able to quickly integrate their internal forces for an external offensive. And this is determined by the limitations of the times and the limitation of manpower.
