In August of the fourth year of Jingyuan (263), the Wei army was divided into three routes to attack Shu, and the general Deng Ai led more than 30,000 troops from Didao (now Lintao, Gansu) to contain the main force of the Shu general Jiang Wei stationed in Huzhong (now northwest of Zhouqu, Gansu); Yongzhou assassin Shi Zhuge Xu led more than 30,000 people to attack Wudu (northwest of present-day Chengxian County, Gansu) to cut off Jiang Wei's retreat; Zhong Hui led the main force of more than 100,000 people, wanting to take advantage of Hanzhong, and then go straight to Chengdu.

With Tingwei Weiquan as the Sima of the Zhenxi Army, Deng Ai and Zhong Hui Military, the festival supervisors. It is commanded by the general Sima Zhao.

The Shu army sent Liao Hua, the general of the right chariot cavalry, to lead the army to reinforce Jiang Wei in the middle of the river; Zhang Yi, the general of the left chariot cavalry, and others went to the Yang'an Pass to refuse. He ordered the generals of Hanzhong to abandon the outlying strongholds of Hanzhong, shrink their forces and retreat to Hancheng (now east of Mianxian County, Shaanxi) and Lecheng. Because the Shu army did not strictly defend the sloping valley, Luogu and meridian valley of the throat and dangerous roads, it was occupied by Wei Xing Taishou Liu Qin.

Zhong Hui then advanced several ways, straight into Hanzhong, left 20,000 people to surround Han and Le Ercheng, led the main force straight down to Yang'an Pass, beheaded Shu general Fu Yan, surrendered Jiang Shu, followed Keguan City (now Yangping Pass, Shaanxi), and drove south.

Deng Ai ordered Tianshui Taishou Wang Qi to attack Jiang Wei's camp directly, ordered Longxi Taishou Zhuan Hong and others to invite Jiang Wei's front, and ordered Jincheng Taishou Yang Xin to attack Gansong. Jiang Weiwen Zhonghui and other troops had entered Hanzhong, knowing that Hanzhong was difficult to protect, he hurriedly got rid of Deng Ai and retreated to Yinping. Yang Xin and others pursued until the mouth of the Xinjiang River, the two sides fought, Jiang Wei was defeated and retreated, and was blocked by Zhuge Xu, who preemptively occupied the bridgehead (southeast of Yinping).

Jiang Wei made a pretend from Kong Hangu to the north and wanted to detour to the east, making it look like he was sending troops to attack the rear of Zhuge Xu, and when Zhuge Xu left the bridgehead for thirty miles to block the attack to the north, Jiang Wei took the opportunity to quickly pass through the bridgehead, and joined forces with Liao Hua and Zhang Yi to defend the Sword Pavilion.

Zhuge Xu rushed to intercept it, but he missed a day and didn't catch up.

…… ……

Deng Ai entered Yinping and wanted to join forces with Zhuge Xu to go south.

Zhuge Xu did not obey, and led the army to the east to move closer to Zhonghui.

Zhong Hui wanted to monopolize military power, falsely accused Zhuge Xu of being afraid of the enemy, escorted him back to punish the crime, and then led the army south, but was blocked by Jiang Wei in the Sword Pavilion.

The Sword Pavilion is known as "one husband is the pass, and ten thousand people are not open", Jiang Wei is guarding with danger, and Zhong will attack the Sword Pavilion, and there is nothing to do. When the Wei army was unable to continue with military rations, Zhong Hui was ready to retreat.

Deng Ai said:

"Now that the thieves have suffered a great setback, they should take advantage of the victory and pursue them. From Yinping along the path, through the Han Deyang Pavilion, rushed to Fuxian, more than 100 miles away from the west of the Sword Pavilion, more than 300 miles away from Chengdu, sent elite troops to directly attack the heart of the enemy. Although Jiang Wei was defending the Sword Pavilion, in this case, he would definitely have to lead troops to rescue Fu County.

At this time, the clock will just take advantage of the void. If Jiang Wei defended the Sword Pavilion and did not save Fu County, then Fu County would have very few troops. The Art of War says: 'Attack it unprepared, take it by surprise.' Attack its empty land today, and you will surely defeat the enemy. ”

In October, Deng Ai took advantage of Jiang Wei's containment by Zhong Hui in the Sword Pavilion, and led the army from Yinping to the south along Jinggu Road East, more than 200 miles south of the Sword Pavilion, and Zhong Hui also sent his generals Tian Zhang and others to follow up.

Deng Ai led the army to climb the trail, dig mountains and open roads, build trestle bridges, and march through the uninhabited dangerous area of more than 700 miles. The mountains are high and the valleys are deep, and it is extremely difficult. On the way, the grain transportation did not continue, and he was in trouble many times.

When the troops walked to Mage Mountain, the road was cut off, and they could not advance or retreat for a while, so Deng Ai took the lead and rolled down the hillside wrapped in felt. Deng Ai led his army by surprise to Jiangyou and forced the general Ma Miao (miǎo) to land.

Zhuge Zhan (Zhuge Liangzi), the general of Shu Guowei, returned to Mianzhu from Fucheng and lined up to wait for Deng Ai.

Deng Ai sent his son Deng Zhong to attack Zhuge Zhan's right flank, and Sima Shishu to attack his left flank. Deng Zhong and Sima Shisu were defeated, retreated, and said to Deng Ai: "The thieves hold firm and are difficult to break. ”

Deng Ai was furious and said: "When life and death are at stake, it's all about this, and what else can you say!" ”

Loudly reprimanded the second general and beheaded him. The two generals rode their horses back, waved the army to fight again, Deng Ai also came to supervise the battle, and finally broke the Shu army, then conquered Mianzhu, and beheaded the Shu general Zhuge Zhan and Shangshu Zhang Zun and others.

After the fall of Mianzhu, the Shu army collapsed on all fronts.

Deng Ai took advantage of the victory to attack, and captured Luoxian (now Guanghanbei, Sichuan) in one go, approaching Chengdu.

Liu Chan, the queen of Shu, was frightened and lost his ground, and felt that the general trend had gone, and under the persuasion of the lord, he sent someone to send the emperor's seal and ribbon, and wrote a letter to Deng Ai to ask for surrender.

Deng Ai led the army into Chengdu, and Shu Han perished.

Liu Chan sent people to the front line to order Jiang Wei and others to surrender, and Jiang Wei and others received the order and went to Zhonghui's army to surrender.

…… ……

In this battle, Deng Ai took advantage of the fact that the main forces of the two armies were holding each other, led the division to surprise the troops, carried out a large depth and detour interspersed, bypassed the frontal defense of the Shu army, and smashed the Shu capital Chengdu, creating a famous surprise attack in the history of Chinese warfare.

Deng Ai entered Chengdu, and Liu Chan led more than 60 princes, kings, and ministers to tie himself up and carry the coffin to the barracks to meet him.

Deng Ai held the talisman in his hand, untied the bindings, burned the coffin, accepted the surrender, and forgave them.

Deng Ai restrained his subordinates, and after entering the city, there was no looting. He pacified the surrendered personnel and reinstated them to their old jobs, which was supported by the Shu people.

However, Deng Ai occupied and stayed overnight in the palace, and it is said that Deng Ai, his son, and his generals all stayed in the palace of Liu Chan's concubines. Deng Ai is even more so, staying in the palace of Liu Chan's concubine Li Zhaoyi, and his son and subordinate generals also frequently enter and stay for a long time.

Therefore, Li Zhaoyi angrily issued such a sentence, "You can't be humiliated!" Then he committed suicide in grief! (From "Romance of the Three Kingdoms")

Li Zhaoyi's "two or three humiliations" does not really refer to it, but only two or three times, but a general number word, which means "continuous", which is in line with Deng Ai's overnight stay and the frequent stay of his son and his generals.

"Romance of the Three Kingdoms" did not directly describe it, because it involved Sima Zhao, as well as Hu Lie, Wei Qian and other famous generals of the Jin Dynasty in the future, how dare Chen Shou write it publicly? Of course, there is another reason, that is, Qiao Zhou, the minister of Shu Han who advocated surrender, is Chen Shou's mentor!

In "Chronicles of the Three Kingdoms", Chen Shou just wrote this sentence: "The army is slight, the dead are lost, and a few days are Anji." "This is a devastating slaughter!

…… ……

In the face of the great victory, Deng Ai arbitrarily followed the previous practice of the Eastern Han general Deng Yu and appointed a large number of officials in the name of the Son of Heaven. He worshiped Liu Chanxing Hussar General, the Prince of Shu Han as the commander of the chariot, and the kings as the commander of the horses; For the ministers of the Shu Han Dynasty, according to their status, they were either appointed as court officials or let them receive their subordinate positions.

Deng Ai appointed Shi to compile and lead the history of Yizhou Thorns, and appointed Longxi Taishou and others to lead the counties and counties in Shuzhong.

Send people to bury the soldiers who died in the battle with the dead of the Shu soldiers in Mianzhu, and build a high platform as a Jingguan to promote their martial arts.

Deng Ai is deeply proud of this great achievement, and often shows boasting and is proud. He once said to the scholars and doctors of the Shu Kingdom: "You are fortunate to have met me, so I am today." If you had met someone like Wu Han, you would have been killed. ”

He also said: "Jiang Wei is naturally a hero for a while, but he met me, so he was at the end of the road." ”

People of insight often laughed at him behind his back when they saw him so boastful.

These became the excuse for the careerist Zhong Hui to put him to death.
