Li Guang was a general from the time of Emperor Wen of Han to Emperor Wu of Han, born into the Longxi family, and spent most of his life fighting, but because of the loss of time in the Battle of Mobei, he finally committed suicide in fear of sin. Whose responsibility should this be?

In 119 BC, after two years of preparation, Emperor Wu of the Han Dynasty concluded that the Xiongnu ignored the fact that it was not difficult for the Han army to travel a long way to attack Mobei, and felt that they had unexpectedly launched the Battle of Mobei. Once you've planned it, put it into action.
Wei Qing and Huo Went sick sent troops to attack the Xiongnu, originally according to the plan, Huo Wentai led the elite troops from Dingxiang to attack Shan Yu, and Wei Qing led Huo to go out of the county after the selection of the disease, responsible for blocking the King of Zuoxian.
At this time, the capture of Yan Shan yu dong, but also ordered the horse to ride out of The Dai County, and ordered the general to send out Dingxiang. The Xiongnu were not stupid, and the history of the Xiongnu believed that they had sent a gap to tell the Han Dynasty that Shan Yu was in the east, while king Zuo Xian was in the north, and Emperor Wu of Han, who had successive great victories, did not think much and directly ordered Wei Qinghuo to attack the line of illness.
As for the purpose of the Xiongnu in doing so, they tried to swallow the Weiqing department after getting rid of the relatively strong Huo Go Sick Department, and then returned to the division to close the door and beat the dogs, and surrounded the Huo Go Sick Department.
Sure enough, after Wei Qing led tens of thousands of troops out of Dingxiang, he captured some Xiongnu and got accurate information, but it was still on the northern side, and Zhao Xin's strategy at that time was very sinister, he believed that the Han army was hungry after a long journey, as long as the Xiongnu lined up to catch turtles in the urn, they could defeat the Han army.
Wei Qing, who had received the latest information, quickly made a decision, leading the main force to meet Shan Yu himself, while sending the right general and the former general to lead a roundabout strategy. In the face of military orders, the former general Li Guang was indignant, believing that he was a former general and should face the enemy head-on, rather than going astray.
Li Guang, who tried to persuade Wei Qing to change the military order, failed to achieve his goal, the general did not listen, which angered the old general, so he went out with the right general with resentment, this time Li Guang once again triggered the lost skill, he and the partial division led by the right general quickly got lost after leaving the host road, and has been circling in the south of the desert.
After Wei Qing arrived in Mobei, although Shan Yu waited in a strict position, Wei Qing seized the opportunity to defeat Shan Yu and fled northward, although he pursued for a day and a night, he still failed to catch up with Shan Yu, which directly led to the failure of the plan to formulate a siege in advance, because the Eastern Route Army failed to arrive on time.
When Wei Qing packed up the battlefield and returned to Southern Mo, he met Li Guang, who was still in the process of getting lost, and sent someone to comfort the old general and ask him about his march, but Li Guang, who had always omitted documents, could not hand them over, and Wei Qing, who wanted to report the course of the war to the emperor, sent someone to urge Li Guang's subordinates.
This angered the old general, and he personally went to Wei Qing's big tent to explain, but when he walked to the Wei Qing shogunate, he said: Guangjiefa fought with the Xiongnu for more than seventy years, and now fortunately from the great general to take orders from the soldiers, and the great general moved back to Guangbu, and lost the way, is not heaven! And for more than sixty years, he could not return to the official of the sword and pen. So he stabbed himself.
The meaning of this passage is that he fought dozens of battles with the Xiongnu all his life, and later followed Wei Qing to attack Shan Yu, but Wei Qing sent him to the east road far away, so he got lost, which can only be regarded as providence, so old and unwilling to face the sword and pen official, so he committed suicide.
Many people feel that it was the operation of Wei Qing and Emperor Wu of Han that caused Li Guang to commit suicide, and the history of the history is that he committed suicide only because he was a dish, as a general, he was unwilling to obey the general's orders, and he could not complete the military planning in advance, and even the minimum combat requirements could not be met.
In the southern part of the country, Wei Qing sent Li Guang out of the right road after receiving news from Shan Yu on his own road, because sima Qian's record thought that Emperor Wu of Han had yin him, but Wei Qing himself knew shan Yu's position after he was out of the plug, how could Emperor Wu of Han explain in advance not to let Li Guang be Shan Yu?
Originally, even Wei Qing could not have been able to meet Shan Yu, because the wrong information only gave Wei Qing the opportunity, which confirmed that Emperor Wu of Han's record of not letting Li Guang meet the Xiongnu in advance was wrong.
What about Wei Qing, after Mo Nan knew Shan Yu's position, he needed to respond separately, at this time, if Li Guang, a veteran of the Three Dynasties, could not lead an army, then the other people were even less qualified and capable, Cao Xiang, or Gongsun Ao, who was the first to go out of the army? Or the unknown Zhao Zhiqi?
Obviously, no matter whether it is fame or combat experience, Li Guang is more in line with the conditions for leading an army alone, and at this time, what is the problem with dispatching Li Guang; moreover, it is the natural duty of a soldier to obey orders, and the general is in charge of the overall situation and sends him to carry out a mission, can he refuse under various pretexts?
Don't let him go, he rushed to go, told him to go and couldn't complete the task, but also blamed the east and the west, the road is not good, there is no water and grass, the road is too far and the wind is too big is not an excuse for the task, the Han army is out of the desert north for the first time, where do you know so many messy things to go, everyone is the first time, why do you want to play special?
Therefore, regarding Li Guang's suicide intention, Wei Qing and Emperor Wu of Han were not responsible, purely his own people were still addicted to food, did not know how many pounds they had, and afterwards did not have the courage to take responsibility and thought of dying, after all, at that time, the law was lost and lost was a capital crime, although it was possible to spend money to atone for his sins, but he ransomed once, and once again there is no money to say, the old face can not pull down ah!
