Someone asked: After Zhuge Liang's death, Jiang Wei, who succeeded him, had several northern expeditions, and what was the state of the war?
After Zhuge Liang's death, in fact, the general trend of the Shu state had gone, relying on the old book left by Zhuge Liang and the internal coup d'état of the Wei state to make this breath not swallow so quickly. Adhering to the legacy of inheriting the ancestors and marquis Wu, Jiang Wei carried out eleven Northern Expeditions before and after in the two states of joining forces in the Northern Expedition and presiding over the Northern Expedition alone, of which there were victories and losses, but there were more victories and fewer losses, which can be seen that Jiang Wei did have certain talents in the military.

Let's take a closer look at jiang Wei's internal relations and northern expedition experience after he grasped the military and political power of the Shu state.
Jiang Wei, as an abandoned general of the State of Wei, in the late Three Kingdoms period on behalf of the State of Shu repeatedly fought against the famous Generals of the Wei Army, Deng Ai, Chen Tai, and Guo Huai, because many ministers in Shuzhong opposed Jiang Wei's Northern Expedition, and after Zhuge Liang's death, the local officials of Yizhou gradually rose under the suppression of the past, and the people within the Shu State who advocated surrender were far greater than those who advocated the Northern Expedition, Liu Chan, although a corporal of Li Xian, did not understand the principle of distinguishing between right and wrong, the eunuch Huang Hao interfered with the power of the dynasty, Jiang Wei wanted to get rid of him, but Huang Hao was deeply loved by Liu Chan, and Jiang Wei was afraid that Huang Hao would retaliate against him. Therefore, in the middle of the Tuntian to avoid disasters, we can also see that in the Shu kingdom, Liu Chan trusted the lord and faction, and we can also see from the side that There was also a certain internal resistance during Jiang Wei's Northern Expedition, which was originally a weak soldier in the country, coupled with the fact that the generals and ministers of the whole country were pregnant with ghosts, and they could not work together, and we could feel Jiang Wei's difficult steps in the political quagmire.
However, despite various unfavorable factors, Jiang Wei's obsession with the Northern Expedition was even worse than Zhuge Liang's, and when Fei Yi and Jiang Wei were in charge of military politics, they went on several Northern Expeditions and repeatedly sent troops west into Qiangzhong, causing Both Yongzhou and Liangzhou's Qianghu to abandon Wei and surrender to Shu, and Wei's Yongzhou assassin Guo Huai and Wei's general Xiahou Ba tried their best to stop it, but the soldiers were defeated by Jiang Wei and were powerless to prevent the rebels from defecting to the Shu state.
Later, sima Yi coup d'état, Jiang Wei thought that the timing was good to try to control the whole of Longxi, wanted to launch a large-scale military campaign, Fei Yi repeatedly restricted, only willing to give him 10,000 soldiers and horses, Fei Yi believed that Qiang Hu was fickle and untrustworthy, and the greatest threat to the Shu state was the State of Wei, not the ethnic minorities attached to the foot of the State of Wei, so the big move relied on unreliable people to respond, afraid of giving the State of Wei an opportunity.
In 253 AD, Fei Yi was assassinated, no one can restrain Jiang Wei, Jiang Wei officially began to preside over the Northern Expedition, this is already the sixth time Jiang Wei waved his division north, that summer he led the army to besiege Nan'an, Wei Army Chen Tai came to the rescue, Jiang Wei retired because of insufficient military food supply, from here we can see that Jiang Wei did not do as well as Zhuge Liang, the Northern Expedition is not prepared to do enough, the grain and grass logistics are too tight, it is impossible to support him in long-term combat, of course, it may also be because Jiang Wei did not have the power of Zhuge Liang in the past, Domestic resources cannot be freely allocated.
In 254, Jiang Wei decided to send an army to Longxi, the Wei official Li Jian surrendered the city, Jiang Wei was unstoppable, surrounded and suppressed Xiangwu, defeated the Wei general Xu Qian, beheaded the public, the Wei army was in chaos, Jiang Wei successively attacked Hejian and Heguan, and moved all the people of each county to the administration of the Shu state. This is also a rare brilliant achievement of the Shu state since the Northern Expedition.
In 255 AD, Jiang Wei again went on the Northern Expedition, broke the Yongzhou Assassination History Wang Jing, the Wei army killed and wounded tens of thousands, and then the Wei general Chen Tai came to relieve the siege, and Jiang Wei withdrew his army to garrison Zhong Ti, but it was still an old problem, logistics could not be guaranteed, and the confrontation was hastily collected soon, and did not expand the results of the battle.
In 256 AD, Jiang Wei took Hu Ji to send troops to the Northern Expedition again in two ways, some people may have seen that almost every year Jiang Wei launched a large-scale Northern Expedition, Jiang Wei's Northern Expedition for many years was indeed a bit of a sense of exhaustion, the army could not rest and was tired of running, the economic center of gravity tilted towards the war, year after year of fighting, the army and the people were miserable, and this Northern Expedition due to the improper cooperation of the Shu general Hu Ji, Jiang Wei was defeated by Deng Ai in Duangu, the Shu army was killed and wounded countless times, and the soldiers of the people began to complain about Jiang Wei. But Jiang Wei did not stop there.
In 257 AD, Zhuge Shi of the State of Wei rebelled against Sima Shi, Jiang Wei saw a rare opportunity, led his army out of Qinchuan, ready to take advantage of the internal turmoil in Wei to seize resources, Sima Wang and Deng Ai could not hold out, Jiang Wei garrisoned Mangshui, and repeated days of provocation without results, the following year Zhuge Wei was defeated and killed, Jiang Wei had no choice but to retreat, and once again returned without success.
At this time, the internal contradictions of the Shu state had reached the point of being unmanageable, and as the tide of opposition to Jiang Wei grew, Liu Chan also began to be dissatisfied with Jiang Wei, and became closer to the officials of the Partial An faction, in 262 AD, Jiang Wei insisted on going his own way and once again sent troops to the Northern Expedition, which was Jiang Wei's last Northern Expedition before his death, but was defeated by deng Ai, an enemy of his life, that is, at this time, the dissatisfaction of the imperial court with Jiang Wei began to erupt, and Jiang Wei became more and more unpopular with Liu Chan.
In 263 AD, the Wei army intended to cut down Shu, Jiang Wei said that Liu Chan hoped to send Liao Hua and Zhang Yi to lead troops to the front line, but Liu Chan did not trust him, and the eunuch Huang Hao even thought that Jiang Wei was using the excuse of defense to call up troops for the Northern Expedition, hoping that Liu Chan would ignore it, and as a result, the Wei army advanced into Shu land, and the Shu state was not the same as the small fight, the army was divided into five roads, the momentum was huge, Liu Chan realized the seriousness of the problem, but it was too late, a large area of land was trampled by the Wei army's iron horse, the Shu army abandoned the pass, the Yin ping stronghold, and withdrew to the Sword Pavilion, and the two sides were deadlocked. However, Deng Ai smuggled from Jinggu Road and directly attacked Liu Chan's doorstep, forcing Liu Chan to order Jiang Wei to surrender, and since then the shu state has exhausted its strength, Jiang Wei surrendered to Zhong Hui, instigated Zhong Hui to rebel, tried to turn the tide, but did not succeed, Jiang Wei and Zhong Hui both died in the Wei rebel army.
If Jiang Wei had not encountered Deng Ai, the enemy of his life, the results of the Northern Expedition should have been greater, and perhaps the birth of Ai He Shengwei was Jiang Wei's heart that jiang Wei could not get over.
