In the official history, the reason why Li Yan was demoted to a commoner was that the supply of grain and grass was only a superficial reason, and Zhuge Liang made up his mind to abolish him, not only because of this one thing. Pen fun and pavilion www.biquge.info

[Li Yan who died]

In the early days of Liu Chan's reign, Zhuge Liang and Li Yan were both auxiliary ministers, and the relationship was still quite close, Li Yan was stationed in Yong'an, guarding against Sun Quan, Zhuge Liang managed the government, recuperated, and probably after the Southern Expedition to Yonghong, Li Yan also wrote a letter to persuade Zhuge Liang to be the king and add nine tin, but Zhuge Liang refused.

According to the records of "Zhuge Liang Collection", there are strict and bright books, and Liang is persuaded to accept Jiuxi and become king. Liang replied: "I have known each other for a long time, but I can no longer understand each other!" Under the feet, the country of light is instructed, and the way of abstaining is not to be acquiesced. I am a corporal in the East, misused in the first emperor, a very human minister, Lu gave tens of billions, and now the thief has not been effective, and the confidant has not answered, and Fang Pet Qi and Jin, sitting on the noble side, is not its righteousness. If Wei is destroyed, the emperor will return to his former residence, and ascend with his sons, although ten lives can be bearable, but it will be worse than nine evils! ”

After Zhuge Liang went north to Hanzhong, Li Yan also helped him win over Meng Da together, and the two directly praised each other, which shows that the relationship is good. But later, the relationship between Zhuge Liang and Li Yan gradually changed, and Li Yan also began his continuous journey to death.

The first thing Li Yanzuo did when he died was to ask for the division of the five counties of Yizhou to establish Bazhou, and he served as the assassin of Bazhou. This is an obvious move to decentralize power, and if it doesn't sound good, it will be suspected of self-reliance. And at that time, Zhuge Liang was ready to send troops to the north, hoping that Li Yan would lead troops to Hanzhong to help him, Li Yan couldn't shirk it in every possible way, and he also took advantage of this rude request to hope that Zhuge Liang would agree, and he really regarded Zhuge Liang as a fool, so Zhuge Liang directly rejected him, and the two may have begun to break up.

In connection with this matter, Li Yan persuaded Zhuge Liang to say that Wang Jiajiuxi was actually likely to have bad intentions, after all, Li Yan was the auxiliary minister left by Liu Bei to Liu Chan, what kind of position did he say this. Things in Bazhou were actually not bad, and soon Li Yan did even worse things.

In the eighth year of Jianxing (230), Cao Zhen made a large-scale crusade against Hanzhong, Cao Wei divided his troops into several ways to attack, the enemy was strong, Zhuge Liang in order to confront Cao Wei, made preparations for another northern expedition, and once again ordered Li Yan to lead troops into Hanzhong, but Li Yan said that Sima Yi and others were recruiting people to be big officials over there, what is this! It's a complete outright threat.

But in the face of the strong Cao Wei, Cao Zhen's terrifying army, Zhuge Liang had no choice, he could no longer turn his face with Li Yan at this time, he could only endure it, he took retreat as advance, not only let Li Yan's son Li Feng be in charge of Jiangzhou affairs, but also let Li Yan protect the affairs of the Prime Minister's Mansion with the central capital, which is equivalent to handing over the power of the imperial court to Li Yan. Li Yan got so many benefits and didn't make trouble, and then Cao Zhen couldn't make the trip because of the rainy season attack, Zhuge Liang sent Wei Yan and other generals to attack, and Shu Han won a big victory.

After this battle, Zhuge Liang must have made up his mind to kill Li Yan, but Li Yan at this time is not easy to deal with, first of all, he and Zhuge Liang are the same auxiliary ministers left by Liu Bei, high and powerful, is the nominal number three person in Shu Han, not only began to manage the affairs of the Prime Minister's Mansion, his son Li Feng also controls the eastern forces of Shu Han from Jiangzhou to Yong'an, there is no decent reason Zhuge Liang can't move Li Yan. What's more, Cao Wei had just been defeated, and Zhuge Liang had to take the opportunity to expand the results of the battle and prepare for another northern expedition in the spring, and there was no extra time and energy to clean up Li Yan, so the situation in Shu Han did not change much for the time being.

It was not until Zhuge Liang personally led the troops to the Northern Expedition to Cao Wei for the fourth time, and withdrew because of the lack of food for the soldiers, and it was Li Yan who transported grain for Zhuge Liang at that time.

But judging from the current data, Li Yan's failure to transport grain in time is not due to his own reasons, but due to objective factors, "Three Kingdoms: Li Yan's Biography" recorded in the "Three Kingdoms: Li Yan's Biography" is "in autumn and summer, it rains in the sky, and the grain is not transported", that is, because of the rainy season, there is really no way, Li Yan failed to guarantee the supply, after all, the supply line of Shu Han itself is relatively long, and it is indeed helpless in the rain. Later, Li Yan sent someone to inform Zhuge Liang, and finally Zhuge Liang withdrew.

In fact, there are no major problems here, Li Yan has a little responsibility at most, Zhuge Liang can't directly knock Li Yan down even if he uses this as an excuse, but he can't stop Li Yan and start to die himself. After Zhuge Liang withdrew from the army, Li Yan not only did not admit that he had given the problem, but instead bit Zhuge Liang back, asking Zhuge Liang why he had enough supplies to withdraw for no reason, and directly put the responsibility on Zhuge Liang, and also wrote to Liu Chan, saying that the army pretended to retreat, but was actually to lure the enemy to eliminate it.

In fact, at this time, Li Yan was already in chaos, and there were no rules for doing things, and he began to contradict himself. On the one hand, he said to Zhuge Liang that he did not admit that he asked him to withdraw the army, and did not admit that he had given the problem, and on the other hand, he told Liu Chan that he had let the Shu army lure the enemy deeper, and did not really let Zhuge Liang retreat.

Overall, Li Yan just didn't want to take responsibility for failing to replenish in time. Why? Personally, I think it's because Li Yan is afraid, after Li Yan threatened Zhuge Liang to gain higher power, he has actually completely offended Zhuge Liang, this Li Yan should also have a number in his heart, so Li Yan didn't dare to give Zhuge Liang an excuse to suppress himself, he was afraid of losing the power he had already reached, he was afraid that Zhuge Liang would attack himself with insufficient supplies, so Li Yan wanted to cover up one of his responsibilities (Li Yan has no actual responsibility for supplies, but has nominal responsibilities, and it is not the first time that supplies are insufficient, So at best, it can only be called a small responsibility), and more mistakes were made, which in the end were completely irreparable.

When Li Yan put the responsibility on Zhuge Liang, in fact, he was already equivalent to declaring war on Zhuge Liang, and when Li Yan wrote to Liu Chan to defend himself, he was actually forcing Liu Chan to choose one of the two, as for the result, it is self-evident.

In other words, the direct reason for Li Yan's final downfall was not because Li Yan failed to transport grain in time on the surface, which led to Zhuge Liang being forced to withdraw from the army, but because Li Yan's failure to transport grain was mainly due to objective reasons, not Li Yan's subjective mistakes, and Li Yan actually only had some nominal responsibility for this.

In fact, in order to cover up the mistake of supply, Li Yan counterattacked wrongly, framed Zhuge Liang, and directly sent the handle to Zhuge Liang. was relegated to the end, and there was no chance to turn over.
