After Zhuge Liang arrived in Hanzhong, he did not immediately launch an offensive, but observed and prepared for a year in advance, and at the same time contacted Meng Da, the old general of Shu Han, in an attempt to attract Meng Da to attach, but unfortunately Meng Da wavered and was finally defeated by Sima Yi.

[Things are not people]

In the first year of Yankang (220), Meng Da rebelled against Shu Han because he was dissatisfied with Liu Feng, took refuge in Cao Wei, and was reused by Cao Pi, the lord of Wei, and became friends with Xiahou Shang, Huan Jie, and others.

However, the world is changing, a few years later, Cao Pi, Huanjie, and Xiahou Shang have all died, Meng Da has almost no allies in the Cao Wei group, and has little contact with Cao Rui, which is equivalent to falling out of favor, so Meng Da is uneasy, and Shu Prime Minister Zhuge Liang secretly corresponded with him and plotted to betray Wei. Coincidentally, Meng Da and Liu Feng were at odds back then, and now they have a gap with Wei Xing Taishou Shenyi.

【Change】

At the beginning, when the Shu general Meng Da surrendered, the Wei Dynasty treated him very favorably. Sima Yi thought that Meng Da's words and deeds were cunning and untrustworthy, but his repeated admonitions were not accepted, and the imperial court also appointed Meng Da as the Taishou of the new city, the marquis, and the fake festival.

Meng Da then connected with Eastern Wu, consolidated Shu's trust in him, and secretly plotted against the Central Plains. Zhuge Liang, the prime minister of Shu, hated Meng Da's capriciousness and worried that he would endanger Shu. Meng Da and Wei Xing Taishou Shen Yi had a grudge, Zhuge Liang wanted to deepen the grudge between them, and sent Guo Mo to deceive Wei to visit Shen Yi, deliberately revealing Meng Da's plan to betray Wei. And Shen Yi and Meng Da were not in harmony, and they had already said several times that Meng Da was ready to take refuge in Shu, so when Meng Da heard that his plan was leaked, he immediately prepared to raise troops.

According to the record of "Wei Luo", Da was not only favored by Emperor Wen, but also friendly with Huanjie and Xiahou Shang, and Emperor Wen collapsed, Shi Huan and Shang both died. When Zhuge Liang heard it, he wanted to lure it, and he counted the books to recruit him, and he repaid him. Wei Xing guarded Shen Yi and Da had a gap, and the secret expression was connected with Shu, and the letter of Emperor Wei was also. King Sima Xuan sent the army to Liang Jizhi and persuaded him to enter the court. Da was frightened and rebelled.

At that time, Emperor Ming had already issued an edict to make Sima Yi garrison Yu Wan, and Jiadu supervised the military of Jing and Henan. He was afraid that Meng Da would quickly send troops, so he wrote to him: "The general abandoned Liu Bei in the past and entrusted himself to our country, and the country entrusted you with the important task of the territory, and entrusted the matter of cutting Shu to the general. No matter how foolish the Shu people are, they hate the general. Zhuge Liang wants to destroy the relationship between you and Wei, but he has no choice. What Guo Mo said is not a trivial matter, how could Zhuge Liang ignore this matter and let Guo Mo leak it, the reason is easy to understand. ”

Meng Da was overjoyed to believe it, and hesitated to seek Wei. Sima Yi secretly marched into the crusade. The generals believed that Meng Da and Wu Shu had a conflict with each other, and they should wait and see before acting. Sima Yi said: "Meng Da has no faith, now is the time for them to be suspicious of each other, and he should be eliminated before he makes a decision." So he marched quickly, traveled two days in one day, and arrived at the foot of Shangyong City in eight days. Wu and Shu each sent their generals to march to Xicheng Anqiao and Muqisai to save Meng Da, and Sima Yi assigned generals to intercept Wu and Shu's armies.

At the beginning, Meng Da wrote to Zhuge Liang and said: "Wan is 800 miles away from Luoyang, 1,200 miles away from me, and when I hear the news of my incident, I should give it to the Son of Heaven, and it will take a month to travel back and forth, and at that time my city has been repaired and solid, and all the armies are ready." I am in the middle of a dangerous road in the mountains, Sima Gong will not come in person, and his subordinates will not be in trouble in the future. When the Wei soldiers arrived, Meng Da told Zhuge Liang again: "I have been in trouble for eight days, and the Wei soldiers have arrived at the city, how fast!" "Shangyong City is blocked by rivers on three sides, and Meng Da erected a wooden fence outside the city to strengthen the city's defenses. Sima Yi crossed the water and destroyed the wooden fence and reached the city. Siege the city in eight ways, attacked for 16 days, Meng Da's nephew Deng Xian, and the general Li Fu opened the door to surrender.

"Wei Luo" records: King Xuan lured Li Fu and his nephew Deng Xian and Xian to open the door to recruit troops. Da was besieged for six days and defeated, and his head was burned in Luoyang Sida's Qu.

After Sima Yi beheaded Meng Da, the head was passed to the Beijing Division. More than 10,000 people were captured, and the army was reorganized and returned to Wan. Encourage agriculture and mulberry, prohibit waste, the people of the south are happy and attached, after the Ming Emperor divided the new city of Shangyong, Wuling, Wuxian for Shangyong County, Xi County for Xi County.

At the beginning, Shen Yi had been in Weixing for a long time, and he was arbitrary in matters of the territory, often pretending to engrave seals and confer officials under the pretense of the emperor's will. Meng Da was killed, and Shen Yi had doubts in her heart. At that time, the county guards sent more gifts to congratulate Sima Yi because of his new victory, but Sima Yi not only did not prohibit it, but also hinted that Shen Yi should also come to congratulate. After Shen Yi arrived, Sima Yi questioned him about the engraving of the holy will, and took him down and sent him to Jingshi. He also moved more than 7,000 of Mengda's remaining people to Youzhou. Shu generals Yao Jing, Zheng He and others led more than 7,000 subordinates to surrender.

[Talking about this matter]

The change of Shangyong in the first year of Taihe (227) is mainly recorded in the Book of Jin, when Zhuge Liang had arrived in Hanzhong, but had not yet launched the Northern Expedition, but actively contacted Meng Da, trying to lead him into chaos, and Meng Da was indecisive, and Wu Shu had contacts, Zhuge Liang then directly linked the fact that the two sides were in contact with the violent Meng Da to revolt.

However, the road is one foot high and the demon is one foot high, Sima Yi's reaction was faster and more positive than Meng Da imagined, although Shu Han and Sun Wu both sent troops to support, but Meng Da was still defeated and killed.

As the saying goes, "character determines fate", and Meng Da's death was actually not unexpected. Earlier, Meng Da served under Liu Bei, and Liu Feng and others pacified Shangyong and other places, and then the two of them first ignored Guan Yu's request for help, and then Neigang, Meng Da finally rebelled against Shu and returned to Wei, not only that, Meng Da later helped the Wei army seize Shangyong and other places. However, a few years later, Meng Da once again disagreed with his colleague Shen Yi and others, and once again had a rebellious heart, if the first time was because of Liu Feng's oppression, then the second time must not blame others.

When Sima Yi attacked Meng Da, although the situation was fierce, it was an obvious fact that Meng Da only held for 16 days, at that time Shu and Wu had already sent troops to rescue, as long as Meng Da could hold out for a while, it should not be a problem to get out of trouble later. Sima Yi later talked about the crusade against Shangyong when he was crusading against Gongsun Yuan in Liaodong, saying that at that time, the Wei army had more soldiers and less food, so it was necessary to fight quickly, that is to say, as long as Meng Da survived the initial predicament, he might even have the opportunity to unite with Shu and Wu troops to kill Sima Yi. As a result, not many days later, Meng Da even turned against his nephew Deng Xian, what else can be said.

Earlier, because of the initiative of Meng Da and Shen Yi in Shangyong and other places, Cao Wei's control of this place was not deep, and after Sima Yi pacified Meng Da's rebellion, he controlled Shen Yi again, and this area was completely controlled by the Wei Dynasty.

Sima Yi's pacification of the Shangyong Rebellion and Xiahou Yuan's rescue of Liangzhou are actually a very obvious contrast. Earlier, after Xiahou Yuan was surrounded by Ma Chao in Jicheng, the seat of Liangzhou, because of the contact with Cao Cao who was far away in Yecheng, the rescue time was delayed, which not only led to the fall of Jicheng, but also repelled by Ma Chao, and then Liangzhou happened again, Xiahou Yuan learned the lesson of the last time and immediately sent troops to drive Ma Chao out of Liangzhou.

And Sima Yi came to Shangyong so quickly and surrounded Meng Da, it can be seen that he must not have received Cao Rui's order, and Xiahou Yuan did it for the second time, and Sima Yi did it for the first time, which is also very thought-provoking.

In addition, Zhuge Liang stayed in Hanzhong for such a long time, and he also had some connection with seducing Meng Da, and after Meng Da failed, it was meaningless for Zhuge Liang to stay, so he quickly sent a direct offensive.

The direct confrontation of Shu Wei was on the verge of breaking out.
