The reason why Jiang Wei left troops to garrison on Jiming Mountain was not only to prevent the Wei army from entering Longxi, but also to the point that thirty miles southeast of Jiming Mountain was Sanguan, which was the northern entrance of Chencang Ancient Road, and you could go directly to Hanzhong through this.

Therefore, Jiang Wei was prepared to stay in Jiming Mountain. If the situation was OK, he could retreat to Longxi, but if the situation was not good, he could retreat directly to Hanzhong. This was a plan of both worlds.

Because Wei is strong and Shu is weak, the national strength of Shu does not allow Jiang Wei to encounter a devastating blow, so every time he sends troops, Jiang Wei must first arrange a retreat and then consider attacking.

Zhuge Liang was cautious all his life. He went to the Central Plains five times. Although the final result was nothing, he lost a lot of losses, because Zhuge Liang would arrange his retreat before every attack. Things can be done, but things cannot be retreated. In short, whenever Zhuge Liang failed the offense, he would stop losses in time, preserve his strength, and leave it to the next attack.

As the successor of Zhuge Liang's legacy, Jiang Wei was undoubtedly inherited by Zhuge Liang in terms of strategy and tactics. Although Jiang Wei is more adventurous than Zhuge Liang, he still inherits Zhuge Liang's prudence in retaining his retreat. The Shu Kingdom's military strength is limited and he can't do it too much.

The Shu army lost almost half of the battle in Chen Cang, which actually exceeded Jiang Wei's psychological bottom line. If it was hit again, Jiang Wei and the entire Shu Kingdom would be unbearable.

Therefore, Jiang Wei hesitated about whether to withdraw troops from Longxi. Although the four counties in Longxi are still under the control of Shu Kingdom, if they have no soldiers to defend, they will not be able to resist the attack of the Wei army. Sooner or later, these counties will fall into the hands of the Wei army again, and will also take over the remaining forces of the Shu army, which is not worth the loss!

Jiang Wei thought about it for a while and finally made up his mind to retreat directly from Jiming Mountain to Hanzhong and give up Longxi.

Of course, Jiang Wei had to discuss such a major strategic decision with Sima Lun. After all, Longxi is the place offered by Sima Lun, and Sima Lun's foundation is here. Whether he is willing to return to Hanzhong with Jiang Wei is unknown, so on that night, Jiang Wei specially invited Sima Lun into his tent, trying to explore Sima Lun's tone and see what he thought.

When Sima Lun came in, he took the initiative to propose the idea of ​​giving up Longxi and withdrawing troops from Hanzhong, which surprised Jiang Wei.

After all, being born is the same and having a different position. For Jiang Wei, Longxi is happy to get it, but not upset to lose it. After all, this is not his own territory, and it is not a big deal for Jiang Wei who has been defeated repeatedly.

But for Simalun, Longxi is already his only foundation. Giving up Longxi means that Simalun will become a rootless piaoping from now on, and can only be entrusted to Shu. Although Simalun, who has tens of thousands of troops, will not be too sad when he arrives in Shu, it is ultimately a difficult thing to accept.

But Simalun seemed calm and said so. The reason why he said this was the result of repeated weighing. Simalun was a person with a great view of the overall situation. He knew how to choose and did not force himself to do anything that could not be done.

When he surrendered to Shu, his generals could not understand at all. Shu was not a very powerful country. The military strength of Shu was equal to the current military strength of Sima Lun. Sima Lun could completely defeat one country by one.

But Sima Lun had his own considerations. Whether Shu is strong or not is another matter, but Cao Liang was too powerful, so powerful that Sima Lun could not compete with him. In this context, Sima Lun had to find allies to fight against Cao Liang.

In fact, Shu Kingdom is not Simalun's most preferred. After all, Shu Kingdom's national strength is extremely weak, and Xiao Neng provides very little assistance to Simalun. However, it is located in Longxi and only borders Shu Kingdom. If Simalun does not choose Shu Kingdom, there is no choice, so Simalun surrendered to Shu without hesitation.

But the facts proved that even if he joined the power of the Shu army, he still could not compete with Cao Liang. The crushing defeat in Chen Cang made Sima Lun clearly realize this. Cao Liang was too powerful. I am afraid that even if Sima Lun gathered the power of the world, it would be difficult to become an enemy of him.

After Chen Cang lost his troops, Longxi's gates were opened, and after half of the troops were lost, Jiang Wei and Sima Lun's troops combined had no hope of defending Longxi. In this case, if Sima Lun continued to hold on to the incomplete and disabled, he would probably have to live and die with Longxi.

So after learning from the pain, Sima Lun finally decided to give up Longxi. Since things cannot be done, why should he try his best to do it?

His idea coincided with Jiang Wei. It was a very similar thing to the hero! He looked at each other for two days, but there was a hint of helplessness and desolation in the laughter.

This was originally a result that no one wanted to see, but now they have to follow this path. The times are forced by fate and fate are a mess.

Since they have made up their minds to withdraw their troops, the Longxi counties must speed up their evacuation. The prefects of the newly appointed counties have not yet been warmed up, so they have to move their nests quickly.

Not only are the officials and troops of each county going to withdraw, but the population of each county going to be moved must be forced to move. The territory cannot be taken away, but the population cannot be left behind for the enemy.

When Liu Bei evacuated Xinye, he brought 100,000 people to cross the Han River. It was not until the Changbanpo of Dangyang that he was caught by Cao Cao's cavalry. When Cao Cao retreated in Hanzhong, he forced to move more than 50,000 households in Hanzhong, resulting in a sparse population of Hanzhong and barren land. As a result, Shu Kingdom spent decades of efforts to restore Hanzhong to the level of the late Eastern Han Dynasty. Zhuge Liang failed the first Northern Expedition and retreated, he also allocated thousands of households in Xixian to Shu.

In the final analysis, the above is still the population. Without population, there will be no taxes, no economy, and no source of troops, so population is the basis of war.

In this great retreat, Jiang Wei naturally would not give up the forced migration of the people of Longxi into Shu. Regardless of the reluctance of the people of Longxi, the migration order must be implemented.

Therefore, the Jimingshan defense line cannot be evacuated for the time being. It is necessary to wait until all the soldiers and civilians in Longxi retreat from Qishan Road before Jiang Wei and Sima Lun retreat from Chencang Road. Before that, even if the Shu army launches the most fierce offensive, it must defend Jimingshan to win more time for the military and civilians in Longxi to retreat.

But Jiang Wei and Sima Lun didn't know that Hu Fen had withdrawn from Jieting. Once Jieting was lost, it was equivalent to opening a hole in Longshan, and Longxi's plan to withdraw troops became a elbow.
