After the failure of the last Northern Expedition of the Shu State and the death of Zhuge Liang, the Shu state regime was crumbling, but it was only surviving. With the assassination of Fei Yi at the first meeting of the year, Shu Han was even more in crisis, and at this time a heroic and decisive and very domineering figure appeared - Jiang Wei.
When Fei Yi was still alive, Jiang Wei was always constrained militarily, and every time he wanted to lead the Northern Expedition, Fei Yi did not allow it, and the number of troops in his hands was only tens of thousands, and the idea of the Northern Expedition had to be suppressed in his heart. However, in 253 BC, Fei Yi was assassinated, and naturally no one took care of Jiang Wei, so the year after Fei Yi's death, Jiang Wei officially became a leader in the army, and Jiang Wei inherited Zhuge Liang's legacy and always remembered to go north to the Central Plains. In his first year in office, he beheaded the Wei general Xu Qian at Xiangwu and moved people from Lintao and Heguan to the Shu state, a battle that was very fruitful, but Jiang Wei was always waiting for an opportunity to make a big northern expedition.
Finally, the emperor did not pay off, the great general Sima Shi of the State of Wei died violently in 255 AD, Sima Zhao took over the power of his brother, but the foundation was still unstable; it just so happened that Guo Huai also died, which was a once-in-a-lifetime good opportunity, Jiang Wei of course would not give up easily, quickly gathered soldiers and horses, and went north again. Because the national strength of the late Shu Han Dynasty was really weak, Jiang Wei brought about 30,000 to 50,000 horses and horses in this Northern Expedition, but on the surface it could not be revealed, so he announced that he would send troops to Jincheng, Shiying, and Qishan in three ways, which frightened the Wei state's Yongzhou Assassin Shi Wang Jing, and hurriedly told the general Chen Tai of Zhengxi to make plans early to meet the Shu Han army.
Who was Chen Tai, he was an old fox, and he saw through Jiang Wei's plan at a glance, so he asked Wang Jing to guard Di Dao and wait for reinforcements to arrive, while he himself sent troops to Chen Cang to give Jiang Wei a two-sided attack. Sure enough, chen tai was expected, Jiang Wei went straight to Di Dao, Wang Jingyi saw that Jiang Wei's army was tired, he forgot Chen Tai's instructions, ready to exert his military talents, a big fight, so he led 50,000 troops to stand on the west bank of the Tao River, ready to confront Jiang Wei's army head-on.
Jiang Wei saw that the Wei army was not panicked, calmly commanded the army, and beat Wang Jing's army to the ground, and Wang Jing quickly led the rest of the people to flee back to the city and wait for reinforcements to arrive. Jiang Wei took advantage of the victory to pursue, and Sima Zhao, knowing this, quickly sent Deng Ai to assist Chen Tai, who lit a beacon and blew horns and drums to boost morale, saying that he would cut off Jiang Wei's back road. Jiang Wei saw that wei reinforcements had come so promptly, and knew that it was impossible to capture Di Dao, so he had to retreat first. However, this battle severely damaged the defensive forces in the Cao Wei Yong prefecture region, shook the people's hearts in the Yongzhou area, and the battle between Shu and Wei invested equal troops, ending in a great victory for shu Han, prompting Jiang Wei to rise for a while, unlimited scenery, and in the second year of the Battle of Taoxi, Jiang Wei was appointed as a general.
Just when Jiang Wei thought that he could make meritorious achievements and restore the former glory of the Shu Kingdom, in fact, the defeat was already decided, and the disparity in national strength between Shu and Wei was huge. In terms of population, the Shu state is only more than 900,000, and the Wei state has more than 4 million, and the population alone is very different; looking at the geographical location, Yizhou is easy to defend and difficult to attack, the supply of grain and grass is very inconvenient, and the battle must be full of grain and grass. Therefore, the Shu state was doomed to survive, and the Northern Expedition was only the last struggle. And Cao Wei can quickly recover after the great war, the Shu state is not, in short, the defeat is determined early, even if Jiang Wei achieves more achievements, he can not save the fate of the Shu kingdom will eventually perish, he can afford the sentence "Jiang Wei died, Han died." ”
