Suppose That Liu Chan does not surrender, waiting for Jiang Wei to return from the Sword Pavilion, attacking Deng Ai back and forth, and Deng Ai will be defeated.
Sima Zhao's battle against Shu made careful arrangements, and his troops were divided into two ways:
1: Deng Ai tangled with Jiang Wei in Puzhong, and Zhuge Xu cut off Jiang Wei's retreat to help.
2: Zhong Hui led the main force of the Wei army to drive straight in, take Hanzhong, and destroy shu Han.
Sima Zhao chose this time very well, and the biggest obstacle to destroying Western Shu was Jiang Wei. At this time, the Shu lord Liu Chan favored the eunuch Huang Hao, huang Hao played with power, and the right general Yan Yu was in cahoots with each other, to seize Jiang Wei's military power, Jiang Wei was worried about being killed, simply hid in the middle of the pile, and did not return to Chengdu.
Jiang Wei was not idle in Puzhong, he had been staring at the movements of the State of Wei, when he heard that Zhong Would rectify the army and horses in Guanzhong, he immediately understood that the battle of the life and death of the Shu State had come, and he could not watch the fall of the Shu State, Jiang Wei immediately gave Liu Chan a table:
Wen Zhong would rule the army in Guanzhong, and if he wanted to make progress, it would be advisable to dispatch Zhang Yi, liao hua to supervise the various armies to protect Yang'an Pass, and Yinping Bridgehead to prevent it.
If Liu Chan listened to Jiang Wei's advice and made arrangements early, Zhong Hui and Deng Ai would be more difficult to destroy Shu than to ascend to heaven. Liu Chan was really worthy of Jiang Wei's loyalty, he asked Huang Hao to discuss, Huang Hao was already at odds with Jiang Wei, he read Jiang Wei's table and thought: You think you are still a great general, pointing fingers at the military arrangements of the Shu kingdom, here I have long been removed, but what way to make Liu Chan not believe Jiang Wei?
This traitor also had a trick, he told Liu Chan that there was a wizard with a special psychic experience, the wizard came to solve everything, Liu Chan had special trust in Huang Hao, and immediately promised to find the wizard into the palace, the wizard gave the result by jumping the big god, wei jun attack was a fictitious thing, don't worry, Liu Chan was completely relieved, did not make the slightest preparation, the minister of culture and martial arts was also in the dark. Such an emperor also said that he had great wisdom, and I don't know how these people thought.
Speaking of Jiang Wei, who was attacked by Deng Ai and Zhuge Xu in two ways, he knew that if he did not escape from the Shu kingdom in time, he pretended to attack Zhuge Xu, and when Zhuge Xu was shrinking his troops, Jiang Wei copied the path to the Sword Pavilion and blocked zhonghui's way to attack Chengdu.
The south side of the Sword Pavilion is relatively flat, easy to transport materials, and the north side is a dangerous road of "one husband and one pass, ten thousand people can not open", Zhong Hui led the army to attack several times, losing troops and breaking generals, and there was no progress. At this time, Deng Ai proposed a plan to smuggle Yin Ping.
Deng Ai planned to march from the Yinping Trail, and the surprise soldiers entered the hinterland of the Shu state and attacked Fu County, and he expected that Jiang Wei would inevitably withdraw his troops from the Sword Pavilion to return to reinforcements, and Zhong Hui would be able to drive straight in and destroy the Shu state.
But the difficulty of smuggling through Yinping exceeded Deng Ai's imagination, his army chiseled mountains along the way, built bridges and paved roads, and so on through the seven hundred miles of desolate mountains, the military food had been exhausted, in this way all the generals of the army would be starved to death, Deng Ai helplessly, the first one wrapped his body in felt, rolled down from the mountain, Wei Jun saw the commander-in-chief so, and there was no way to retreat, they also plucked up the courage to climb down from the cliff, the soldiers pointed directly at Jiangyou, what they could not imagine was that the Jiangyou defender Ma Mi surrendered, which was simply an accident. If Ma Mi went all out to meet the battle, with Deng Ai's tired division, Deng Ai's smuggling of Yin Ping would also end in failure, and Deng Ai's success was a fluke.
Deng Ai replenished personnel and materials in Jiangyou, led the army forward, defeated Zhuge Zhan, and Liu Chan of Chengdu fully cooperated, ordered people to tie himself up, and led Wenwu out of the city to surrender, which cannot be blamed on Liu Chan, who was originally "unable to support Adou"? The Shu kingdom thus perished.
If Liu Chan chose to stick to it, it would be "Ah Dou who could afford to support", Deng Ai's plan to smuggle into Yinping originally did not think of fighting alone to destroy the Shu Kingdom, he was just cooperating with Zhong Hui, only Zhong Hui's army from the Sword Pavilion into Xichuan, in order to destroy the Shu Kingdom, Deng Ai thought that Liu Chan was such a weak chicken, and even fell without a fight.
Deng Ai's battle plan to cooperate with Zhong Hui was not feasible. Zhong Hui's army could not be attacked for a long time in the Sword Pavilion, hundreds of thousands of troops had to spend how much grain per day, Shu Dao was too difficult, and the road was far away, grain could not be transported, Zhong Hui consulted with the generals, in the fight may suffer losses, decided to withdraw back, at this time Jiang Wei received Liu Chan's surrender will, Shang Zhong hui camp please surrender.
If Jiang Wei did not surrender to Zhong Hui, with the communication conditions at that time, it was estimated that Zhong Hui would not know where Deng Ai was, and Zhong Hui would withdraw, and Jiang Wei would be able to deal with Deng Ai with all his might.
Liu Chan did not surrender, the Shu generals and the people were still willing to follow Liu Chan, although Liu Chan fainted, but not brutal, he did not persecute the loyal generals, Zhuge Liang, Fei Yi, Dong Yun, all under Liu Chan to get a good death, Jiang Wei's army received Liu Chan's surrender order, angrily drew his sword and cut stones, it can be seen that the army is also willing to be loyal to Liu Chan.
As long as Liu Chan persisted, and the Shu state surrendered to Deng Ai's men and horses, it was entirely possible that they would defect before the battle. Deng Ai's Wei army reached Jiangyou with only two thousand men, and only increased its strength by collecting the Shu state's surrenders, Jiang Wei returned to attack Deng Ai, Liu Chan transferred troops from all over Xichuan to be under the command of Jiang Wei, Deng Ai would immediately fall into an unfavorable situation, with Jiang Wei's military ability, he was not afraid of Deng Ai, Deng Ai fought alone, and would not be Jiang Wei's opponent.
Moreover, the generals of the Wei army were also not in harmony, Zhong Hui had a rebellious heart, he was bent on expanding his strength, Deng Ai and Zhuge Xu did not leave Jiang Wei in Puzhong, when Deng Ai smuggled into Yinping, Zhuge Xu led his army to the Sword Pavilion and Zhong Hui to meet. The first thing Zhong Hui did was to load Zhuge Xu into a prison cart and annex Zhuge Xu's army. As a person of Zhong Hui, he preferred Deng Ai to die in Xichuan, so that in the battle to destroy Shu, Zhong Hui occupied Hanzhong, which was also a great achievement.
Summary: If Liu Chan does not surrender, sticks to the aid, and waits for Jiang Wei to return to attack Deng Ai together, all factors are unfavorable to Deng Ai, Deng Ai will eventually be defeated by Jiang Wei, although the Shu state lost Hanzhong, but can keep the Territory of Xichuan, the Shu state will not perish.
