Ancient society believes that "good subjects choose the lord and do things, loyal subjects do not do two lords", which is the embodiment of the ancient people's monarchical thinking, which lasted for more than two thousand years, it is this kind of thinking that binds the courtiers, most of the courtiers want to become "loyal subjects", they also realize their wishes, but there are also some "wall grass" courtiers in history, who can betray the original monarch and choose a new monarch, they will be condemned by history, no matter how great their achievements. During the Three Kingdoms period, Jiang Wei, a great general of the Shu Han Dynasty, made many military achievements for the Shu Han, but he had no small controversy in history, because he betrayed the State of Wei and surrendered to the Shu Han.
Jiang Wei was originally a vassal of Cao Wei, his father Jiang Wei died for Cao Wei, and after his father's death, Jiang Wei was given the title of Zhonglang (中郎) and joined the army in Tianshui County, at this time Jiang Wei's military talents had not yet been fully revealed. In 228 AD, that is, in the sixth year of Jianxing, the Shu Han chancellor Zhuge Liang led a large army to attack Qishan, Jiang Wei and Gong Cao Liangxu, the main bookkeeper Yin Reward, the main record Liang Qian, and others from Tianshui Taishou Ma Zun patrolled everywhere, Nan'an, Tianshui and Anding three counties opposed Wei Shu, Ma Zun as Cao Wei's courtiers, thinking that all his subordinates were betrayed, he fled overnight, leaving Jiang Wei and others, when Jiang Wei and others went to Ji County, they were not allowed to enter the city, so Jiang Wei had no choice but to surrender to Zhuge Liang.
From this point of view, Jiang Wei's rebellion was really a helpless move, he had no intention of betrayal, he was completely forced, fortunately, Zhuge Liang had the ability to know people, and wrote a letter to the Shu Han Jiang Wan (after Zhuge Liang's death, Jiang Huan succeeded to the post of prime minister) saying that Jiang Wei was a sergeant of Liangzhou and had courage, after which Jiang Wei commanded sergeant Liangzhou, had courage, and was later promoted to the general of the Central Supervision Army Zhengxi. In the twelfth year of Jianxing, Zhuge Liang died of illness, Yang Yi and others led the army back, Jiang Wei and others followed Zhuge Liang's will, secretly did not mourn, slowly retreated from the army, after returning, Jiang Wei was appointed as the auxiliary Han general of the Right Supervision Army, and was given the title of Marquis of Xiangping.
Jiang Wei gradually became an important general of the Shu Han Dynasty, was entrusted with the management of the internal and external military, in 254 AD, Jiang Wei led the army out of Longxi, in two years, Jiang Wei made great military achievements, first repelled the Wei army, beheaded the Wei general Xu Qian, took advantage of the victory to pursue, occupied a number of regions, and then led tens of thousands of soldiers to attack Cao Wei, in Taoxi to break the Wei state of Yongzhou to assassinate the Wang Jing, killing tens of thousands of Wei troops. Cao Wei's great defeat brought Jiang Wei's prestige in Shu Han to the peak, so he was promoted to the rank of general, and he showed outstanding military talent in this great battle, and the whole of Yongzhou was almost overthrown, which was a record that Zhuge Liang and Lu Xun had not achieved in the Northern Expedition before!
However, after that, Jiang Wei was not able to maintain his prestige, he intended to continue to attack Wei, originally planned to send troops with the Zhenxi general Hu Ji to fight together, but Hu Ji did not come, Wei general Deng Ai defeated Jiang Wei at Duangu, Jiang Wei's army suffered heavy losses, Jiang Wei autonomously made a mistake, so he asked to be demoted to a rear general and do great general work. Later, Jiang Wei was still bent on planning to cut down Wei, but since the Battle of Taoxi, the State of Wei had already sent tens of thousands of troops to guard against Shu Han, but Jiang Wei was still fighting with the Wei army, and he challenged many times, and the Wei state defenders have not been able to meet the battle.
In fact, this is related to Zhuge Liang's last wish, it was Zhuge Liang's kindness that allowed Jiang Wei to show his skills in the army, which he did not have in the Wei kingdom before, and Zhuge Liang has also been cultivating and reusing him, so Jiang Wei will be bent on the Northern Expedition and vow to complete Zhuge Liang's last wish.
Unfortunately, Shu Han already had no power to return to heaven, when Liu Bei lent Guan Yu revenge during the Shu Han Dynasty, a large-scale crusade against Eastern Wu, but unfortunately, the State of Wu achieved the final victory, and the Shu Han was seriously injured, just losing tens of thousands of people had already made Shu Han collapse, but the State of Wei lost tens of thousands of soldiers in the Battle of Taoxi, but there was not much impact at all, but Shu Han thought that it had achieved a great victory.
At that time, the State of Wei did not put Shu Han in his eyes, but focused on guarding against Eastern Wu, the central and eastern front forces of the State of Wei were used against Eastern Wu, only the western front was used against Shu Han, if Jiang Wei could take advantage of the victory and attack the western front of Wei, it would be very easy.
But Jiang Wei had been dying di Dao, he had originally thought of attracting Chen Tai to rescue Di Dao, and then annihilating Cao Wei's reinforcements, but Cao Wei's defenders could not avoid fighting, and Jiang Wei's army was completely consumed here, and it was useless at all.
It was not until 258 AD, when Zhuge Wei was defeated and killed, that Jiang Wei returned to Shu Han, where he once again held the post of general, and when Jiang Wei led the army to attack Wei again, he was defeated again by Deng Ai and could only retreat to Puzhong. Poor Jiang Wei was bent on serving the country, but there was still a eunuch Huang Hao in the dprk who targeted him and planned to depose Jiang Wei, Jiang Wei also saw this person's intentions and asked Liu Chan to kill Huang Hao, but Liu Chan did not agree, and Jiang Wei was afraid of going back to be targeted by Jiang Wei, so he stayed in Puzhong to plant wheat.
In 263 AD, when the Wei army cut down Shu, Jiang Wei saw the signs and asked the imperial court to take precautions, but Huang Hao listened to the ghost god and told Liu Chan that there was no enemy army coming, so Shu Han did not make defensive preparations, until the Wei army really came, Liu Chan sent an army to support Chuzhong, Shu Han's national strength was not as good as Cao Wei's branch army, Jiang Wei could not resist at all, Cao Wei generals wrote to persuade Jiang Wei to surrender, but Jiang Wei did not respond at all. Cao Wei's army forced Liu Chan to surrender Kaesong, and Liu Chan also ordered Jiang Wei to surrender, which was another betrayal against his will, and Jiang Wei could only accept it.
After Jiang Wei surrendered, he was still thinking about restoring the country, until Zhong Hui had the intention of rebellion, so he persuaded Zhong Hui to rebel together and kill wei generals, but in the end, the matter was revealed, and both Jiang Wei and Zhong Hui were killed. In this way, it seems that Jiang Wei was bent on Shu Han, but unfortunately when Shu Han arrived in his hands, he became a mess, but in the eyes of many people, he was an unfaithful and treasonous person, and in the eyes of historians, he was criticized as a soldier who was poor and militaristic, and a soldier who was very happy to make great achievements, if he was in the heyday of Shu Han, perhaps belligerence would not be a shortcoming.
