Before Zhuge Liang died, why did he tell Yang Yi and them, this Wei Yan is afraid that he will not listen to orders, if he does not listen to orders, you will leave yours. Leave him alone, why?Now I think everyone should understand.
Just because Wei Yan was an unswerving anti-Cao element, not only was he not an anti-thief, but also a resolute anti-Cao element, Zhuge Liang expected that he would not give up the Northern Expedition. He must continue to fight, and Zhuge Liang knows Wei Yan very well, what about this, he is pretentious and thinks very highly of himself, when Zhuge Liang was alive, he always felt unwilling. I didn't enjoy that battle, but Zhuge Liang's prestige was too high, he couldn't help it, now that Zhuge Liang has died, Yang Yi, Jiang Wei, and Fei Yi can't suppress Wei Yan, and Wei Yan won't listen to them. So I had to let him go, there was no way, I couldn't keep it, I couldn't stop it.
Therefore, Zhuge Liang's last order is very clear, "If you delay or do not obey the order, the army will spontaneously", that is, you go yours, regardless of him, did not say that if Wei Yan did not obey the order, you would kill him, because Zhuge Liang knew very well in his heart that Wei Yan was by no means a thief. It's just that there is no way, because at this time, the most important thing is to quickly withdraw the army to Chengdu and defend the Shu Han regime.
Only by preserving Shu Han, the future revival of the Han dynasty will be returned to the old capital, and there may be a glimmer of hope. If even Shu Han can't be saved, then there is no hope at all. In order to take care of the overall situation, at this time, I had to say, go with Wei Yan.
After the battle of Hanzhong, Liu Bei established himself as the king of Hanzhong and moved back to Chengdu. I didn't want Liu Bei to promote Wei Yan to be the general of Hanzhong Zhenyuan and the Taishou of Hanzhong, and the whole army was shocked. For this reason, Liu Bei asked Wei Yan: "I appointed you with a heavy responsibility today, how do you want to deal with it after you take office?"Wei Yan said: "If Cao Cao comes from all over the world, please refuse it for the king."Partial to the 100,000 people, please swallow it for the king. Liu Bei said yes, and the ministers also felt very bold about what he said.
During Zhuge Liang's Northern Expedition, Wei Yan served as a former military division and participated in the decision-making of the front-line war during the Northern Expedition. During Zhuge Liang's Fourth Northern Expedition, Wei Yan, Gao Xiang, and Wu Ban fought against Sima Yi, and the Wei army was defeated. In this battle, the Han army won 3,000 armor levels, 5,000 collars of armor, and 3,100 crossbows.
Zhuge Liang handed over his military power to Yang Yi and put Wei Yan in charge of the rear. However, Wei Yan was not satisfied with this arrangement, believing that his qualifications were older than Yang Yi's and that he should take Zhuge Liang's place. After Zhuge Liang's death, Wei Yan began to clash with Yang Yi, which eventually led to the "Wei Yan ** Yang Yi Incident".
The Wei Yan** Yang Yi incident occurred after Zhuge Liang's death. When Zhuge Liang was seriously ill, he arranged the deployment of the retreat and the route of the withdrawal of troops and other related issues. He handed over the military power of the Sichuan and Shu army to Yang Yi, and asked Wang Ping, Fei Yi, Jiang Wei and others to obey Yang Yi's military orders. However, Wei Yan was not invited to participate in this decision-making process.
After Zhuge Liang's death, Wei Yan was dissatisfied and angry about it. He didn't want to withdraw his troops, thinking that he should continue to fight and reclaim the world. Wei Yan's words and actions also showed his dissatisfaction and dissatisfaction with Yang Yi. For example, he said: "Although the prime minister is dead, I see it." The relatives and officials of the government can return the funeral to the burial, and I should lead the army to fight the thief”
Wang Ping was also an important figure in this incident. He was a general of Shu Han, who followed Zhuge Liang on his Northern Expedition and excelled in the Battle of Jieting. In the incident of Wei Yan ** Yang Yi, Wang Ping, as Yang Yi's subordinate, tried his best to assist Yang Yi, and protected Yang Yi at a critical moment, allowing him to escape Wei Yan's pursuit.
In this case, Wei Yan took the lead in returning south, burning the plank roads along the road, and attacking Yang Yi's army. However, he was unsuccessful and eventually had to flee. In Hanzhong, he was chased and killed by Ma Dai.
