At the end of the Eastern Han Dynasty, the world was divided into three parts, and three opposing regimes of Wei, Shu, and Wu appeared on the land of China, and people with a little common sense knew that among these three countries, the State of Wei was the most powerful, the State of Wu was the second, and the State of Shu was the weakest existence.
Although the State of Shu has always been the protagonist in the re-enactment, it has not been able to change this fact. However, when the three countries were destroyed, the Shu state performed quite heroically compared with the previous two countries.
As we all know, liu chan, the lord of the Shu Dynasty, was really a lot worse than his father, in 263 AD, the Shu kingdom was already greatly reduced in strength due to Jiang Wei's successive years of conquest, and the house leaked during the overnight rain, and the Wei state began to take the initiative to attack the Shu state at this time. Although Jiang Wei made a series of resistances, he still failed because Liu Chan listened to the traitors, and after the fall of Hanzhong, he re-established the defensive line at the Sword Pavilion. However, he did not think that Deng Ai bypassed the defensive line formed by Jiang Wei and defeated Zhuge Zhan at Mianzhu Pass. After this news reached the State of Shu, Liu Chan decided to abandon resistance and submit to the State of Wei. Although Jiang Wei made a plan to restore the country, it also ended in failure.
In fact, during this period, the Shu Han, who had already perished, actually fought a hard battle. Before we talk about this battle, let's first look at what happened before.
In order to retake Jingzhou, Liu Bei personally led a large army to attack Eastern Wu, but did not want to be defeated by an unknown Lu Xun, so Liu Bei retreated to Yong'an (White Emperor City). Because of the loss of face, Liu Bei simply stayed in Yong'an Tun and prepared to face the Eastern Wu army here, and had another opportunity to counterattack. Unfortunately, Later, Liu Bei fell seriously ill and ultimately failed to realize this wish, and the heavy responsibility of garrisoning Yong'an fell to Li Yan's body, and Yong'an became the eastern gate of Shu Han.
By the time of the fall of the Shu Han Dynasty, the governor of Yong'an had changed several times, and it was Yan Yu at that time. When he learned of Zhuge Zhan's death, he led a large army to rescue Chengdu, and the defensive task of Yong'an City was entrusted to Luo Xian. Luo Xian had served as a prince in Chengdu, but because he had offended the eunuch Huang Hao, he was transferred out of the power center of Shu Han and became Yan Yu's deputy general at Yong'an.
Before the fall of the Shu Han Dynasty, they had asked for help from the State of Wu, but the Wu army that came to the rescue sat back and watched the success or failure, and seeing that the State of Shu was destroyed, they stepped up their speed to march towards Yong'an, and their purpose was obvious, but they wanted to take the opportunity to divide the State of Shu.
At this time, the Yong'an defender was Luo Xian, who was very angry in the face of this shameful behavior of the State of Wu, and although the State of Shu had surrendered, he resolutely reorganized his soldiers and prepared to block the Wu army.
As mentioned earlier, Yan Yu took yong'an's main force with him in order to rescue Chengdu, so Luo Xian now had only a small number of defenders for him to dispatch. What's more, after the news of Liu Chan's surrender reached Yong'an, many people took advantage of the chaos and fled. Compared with the army of the State of Wu, Luo Xian was obviously in a weak position, and the only advantage was that Yong'an City was strategically located, and in order to be prepared, the walls were high and thick.
Under these conditions, Luo Xian still led the remaining troops to fight with the Wu army, and from 263 AD to 264 AD, Luo Xian repelled the large-scale attacks of Sheng Man, Bu Xie, and Lu Kang.
However, it was also a loss of troops, and the strength of the troops in Yong'an City was less than half of the original, and it had caught up with the large-scale plague, and the real combat effectiveness was very small. Fortunately, the Wei general Hu Lie began to attack Xiling, and the Wu army besieging Yong'an was forced to retreat.
Afterwards, Luo Xian was highly valued by Sima Yan and became the founding general of the Western Jin Dynasty. Although the State of Shu had already surrendered to Wei at that time, luo xian had nominally belonged to Wei Chen, but because of the chaos, Luo Xian's defensive battle could also be regarded as the last battle of the Shu state.
