Personally, I think Jiang Wei can be called a general with both wisdom and courage, and he is also known as the five famous soldiers in the late Three Kingdoms with Wargo, Zhong Hui, Lu Kang and yang hu. Jiang Wei is a typical "scholar dies for a bosom friend" and a loyal heir of Zhuge Liang. Jiang Wei's Northern Expedition has always been praised more than praised less. For example, in the long poem at the end of Romance of the Three Kingdoms, there is a saying that "Jiang Wei went to the Central Plains alone and made great achievements". Most people also believe that Jiang Wei's Northern Expedition greatly consumed the financial and material resources of Shu Han, which led to the demise of Wei Jun in the future. Is that really the case? If nothing else, let's take a look at Jiang Wei's previous northern expeditions in history. According to the Records of the Three Kingdoms, Jiang Wei made more than nine northern expeditions, but eleven. For the first time, in 238 AD, Jiang Wei and Jiang Wan cooperated in Longyou. As a result, Wei Jun and Nan 'an are at loggerheads. In 244 AD, Jiang Wei and Wang Ping sent troops to attack Cao Shuang, the general of Wei. Cao Shuang's defeat barely saved Guanzhong. The third time, in 248 AD, Jiang Wei led an army out of Longxi to fight Taoxi with Wei generals Guo Huai and others, thus subduing Liangzhou Bai and taking him alive. The fourth time, in 249 AD, Jiang Wei sent Liao Hua to Taocheng. Because Wargo got the information in advance, Liao Hua failed. The fifth time, in 250 AD, Jiang Wei, supplemented by Hu Qiang, fought with Guo Huai in Taoxi, drawing. The sixth time, in 254 AD, Jiang Weiling surrounded Nan 'an, and withdrew voluntarily because of lack of food and grass. For the seventh time, in 255 AD, Jiang Wei went to Didao, Longxi, and Wei surrendered. Wei attacked Xiaheguan and Lintao counties and killed Wei. The eighth time, in 256 AD, Jiang Wei returned to Germany, defeated Wang Jing, the secretariat of Yongzhou, and killed tens of thousands of Wei Jun. After that, Wei Jun sent reinforcements on a large scale and lost ground. The ninth time, in 257 AD, Jiang Wei and Wargo fought in Duangu. Due to the failure of Shu general Hu Ji, the Shu army was defeated and suffered heavy casualties. For the tenth time, in 258 AD, Jiang Wei rebelled against Huainan with Zhuge Dan, leading tens of thousands of people out of Luogu, and was at loggerheads with Wargo. Zhuge Dan was defeated, and Jiang Wei led the troops back. The eleventh time, in 26 1 year, Jiang Wei led his troops into Qinchuan, but was separated by Wargo, so he withdrew. Throughout Jiang Wei's previous northern expeditions, the specific achievements are as follows: winning twice; Small wins three times; Not four times apart; A big defeat, a small defeat. Generally speaking, we still win more and lose less, and the loss of the army is also Wei's attention to Shu. Moreover, the base point of Jiang Wei's Northern Expedition has been pushed from West Qinling County and Woods Valley in Zhuge Liang's era to Jincheng in the north of West County and Mangshui in the south bank of Wei River. It is precisely because Jiang Wei has repeatedly defeated Cao Wei's generals Cao Shuang and Wang Jing that Wei Jun has been stuck in the Qinling Mountains. Shu Han, with a small land and a large population, forced Cao Wei, a powerful country with Kyushu, to take strategic defense for 30 years, which is extremely rare in China's military history. As for the two failures of the Northern Expedition, they were all defeated by the general of Wei State, Wargo. I always thought that Wargo was the best general of Wei. Moreover, Jiang Wei attacked, Wargo defended, and Wei was also superior in terms of troops and materials. Jiang Wei deserved to be defeated by him. It is no exaggeration to say that Jiang Wei's Northern Expedition maintained the declining Shu-Han regime to some extent. Some people say that Jiang Wei's northern expedition caused Shu Han's "soldiers trapped and people tired", which is indeed inevitable, but Wei also suffered losses, and Wei's losses as the defeated party were far greater than Shu Han's, so we might as well think that it was Jiang Wei's active northern expedition that narrowed the national strength gap between Shu and Wei. [Danger] There is a view that winning by surprise is easy to defend but difficult to attack. It is good to insist on consuming Wei Jun, so as not to be eliminated prematurely. This sentence is good in theory, but I also want to quote a sentence from Chi Shangbin, head coach of Xiamen Xiamen New Team, "You can't stay." Huan Wen conquered West Shu with 7,000 soldiers in the Eastern Jin Dynasty! The strategy of defending Chengdu by attacking instead of defending, actively exploring the north and taking Hanzhong as the barrier was set by Zhuge Liang during his lifetime. If this is wrong, then Jiang Wei is just continuing Zhuge Liang's mistake. After Zhuge Liang's death, the talents of Shu Han declined sharply, and the court was gradually controlled by treacherous court officials. Among them, Liu Chan's favorite eunuch Huang Hao is the most prominent. When Dong Yun was alive, every time he saw Huang Hao, he would denounce him, so Huang Hao dared not make a difference. When Dong Yun died, no one in North Korea could stop him. Jiang Wei wanted to go out to find Huang Hao, but Liu Chan stopped him. Therefore, Huang Hao was jealous of Jiang Wei, and repeatedly wanted to take Jiang Wei's relieving power and then murder him. Jiang Wei knows very well that he dare not give up the relieving. And the only way to keep the military power is to lead troops to fight. Why do you need to defeat the enemy without fighting? There is a simple reason. If Jiang Wei adopts the strategy of sticking to the city wall, he will soon be deprived of military power and replaced by Yan Yu, a close confidant of Huang Hao. Please think about the friends who hold the theory of "sticking to the end". How long can Shu people keep Yanyu's troops? Thirty years? Three years is good! At the end of Shu and Han Dynasties, there were not many outstanding generals, only Wang Ping, Liao Hua, Zhang Yi and later Xia Houba. Facing the powerful Wei Jun, Jiang Wei should shoulder the full responsibility of commander-in-chief, general and staff officer. Anyone who knows a little about the military can understand the difficulty of Jiang Wei's battle at that time, but even under such conditions, Jiang Wei can still win tactically. What reason do we have to accuse him?
