In 219, Guan Yu was killed by the Eastern Wu general Ma Zhong. Guan Yu's death not only caused the Shu state to lose a major general, because the Jingzhou that Guan Yu was defending was breached, so it meant that the door of the Shu state was opened from then on. But this was only the fuse for the shu state to perish.
In 221 AD, Liu Bei declared himself emperor in Yizhou, and in the same year, In order to avenge his brother, Liu Bei launched the famous Battle of Yiling. At that time, the group of ministers in the Shu kingdom, led by Zhuge Liang, all opposed Liu Bei's move to attack Wu, and Sun Quan also sent emissaries to ask Liu Bei for peace. However, Liu Bei, who was determined to go his own way, still chose to launch the Battle of Yiling.
The Battle of Yiling ended with the defeat of the Shu state, and it was this war that caused the Shu state to suffer heavy losses. The Battle of Yiling not only cost the Shu state 50,000 elite soldiers, but Liu Bei also died in the White Emperor's City because of this battle. Before the Battle of Yiling broke out, Guan Yu, Guan Ping, and Zhou Cang were killed one after another. Subsequently, Liu Bei executed his righteous son Liu Feng. These can be said to be the elite of the Shu state's military generals. After Liu Feng's death, Shangyong was lost. In 220 AD, Fa Zheng died of illness. Just as Liu Bei was preparing to launch the Battle of Yiling, Zhang Fei was also killed by his men in 221 AD. Huang Zhong then fell ill and died in Chengdu. In 222 AD, in the middle of the Battle of Yiling, Ma Chao also died of illness in Chengdu.
The Shu state was the weakest of the three kingdoms, and it was only after Liu Bei and Zhuge Liang's efforts to govern the shu state that its strength was enhanced. It was the Battle of Yiling that caused the Shu state to lose a large number of elite soldiers, and it was also during the Battle of Yiling that the Shu state lost four of the five tiger generals in succession. The Shu kingdom was originally short of talent, and Shu Zhongwu would be led by the Five Tigers General. After the death of four of the Five Tiger Generals, his successors Zhang Nan and Feng Xi and Zhuge Liang's warlords of the Southern Barbarian tribe: Mo Ke and Fu Tong were also killed on the battlefield of the Battle of Yiling.
Regarding Fa Zheng's death, Zhuge Liang once lamented: If Fa Xiaozhi is still alive, he will definitely be able to stop Liu Bei's eastern crusade. Even if Fa Zheng could not stop Liu Bei, he would not let the Shu army return with a big defeat. From this, it can be seen that Zhuge Liang felt that the Battle of Yiling was a strategically wrong choice made by Liu Bei. The death of the elite warrior proved that Zhuge Liang's judgment was correct. In addition, Liu Bei also died of illness in the White Emperor City because of the Battle of Yiling, which made the Shu Kingdom have no main heart bone since then, which was a greater blow to the spirit of the Shu Kingdom.
Liu Bei's entrustment to Zhuge Liang at the White Emperor's City undoubtedly showed that he had realized the mistake of launching the Battle of Yiling. As a monarch, Liu Beidu has bowed to Zhuge Liang, what choice can Zhuge Liang make? It can only be bowed down and died. Therefore, Zhuge Liang knew that he could not do anything, and he also had to work hard to do it, and led several wars in the Northern Expedition of the Shu Army in the Central Plains. Zhuge Liang's northern expedition to the Central Plains once again caused the Shu state to lose troops. The Shu kingdom, whose strength was constantly declining and its talents were withering away, was doomed to be destroyed by Cao Wei.
