In the later period of the Three Kingdoms, the three-legged situation that had been maintained for decades collapsed with the first destruction of the Shu Kingdom. In 263 AD, Sima Zhao, a powerful minister of Wei, sent troops to 5 roads and attacked Shu on a large scale. In the face of the menacing Wei army, Liu Chan, the queen of Shu, actually listened to the words of the eunuch Huang Hao and did not take any measures to resist.
After the fall of Shu in the later period of the Three Kingdoms, the confrontation between Jin and Wu lasted for more than ten years, how did Wu hold on for many years?
In this fierce confrontation, the reason why Wu was able to hold out for many years is mainly due to the following reasons:
1. The northern regime has entered a critical period of change. Originally, the north was the Cao Wei regime, but after the change of Gaopingling, the Cao family lost power to the Sima family, and the Sima family has been in power for a long time since then. But the political purpose of the Sima family is not simple, they are not willing to be the Duke of Zhou or Zhaogong, but they are more willing to be the emperor. After a long period of operation, Sima finally had the conditions to be the emperor. The War of Exterminating Shu was the charge of the Sima clan on the road to becoming the emperor, and Sima Zhao quickly promoted to the Duke of Jin and the King of Jin by virtue of his exploits in destroying Shu.
2. The Jin Dynasty needed to solve the problem of foreign invasion first. Xianbei leader bald tree function in the first six years of Tai (270 years) to rebel, to the first year of Xianning (275 years) almost monopolized Liangzhou, Xianning three years (277 years) March, Pingyu Protector Wen Yang led the army to crusade, although victorious, but the next year, bald tree function and captured Liangzhou, five years (279 years), Jin Wu Emperor Sima Yan appointed Ma Long as the Pinglu Protector, led the army to defeat and kill the bald tree function, completely pacified Liangzhou. You must know that the assassin is the governor of a state, a veritable high-ranking official. At the beginning, he didn't die much against Shu and Wu, but three in a row died, and the impact can be imagined. Even Sima Yan himself lamented that Wu and Shu were not so powerful back then. For Jin, it is imminent to solve the border rebellion, and the destruction of Jin can only be postponed.
3. It is because Eastern Wu still has a certain amount of strength, and the Jin Dynasty has been unable to make up its mind to destroy Wu for a long time. Although Eastern Wu seemed to be the weakest during the Three Kingdoms period, Eastern Wu was still very strong in military mobilization and the ability to resist invasion, relying on the Yangtze River natural danger, if it were not for Sun Hao's brutality and inhumanity that led to the collapse of the internal division, Sima Yan would not dare to attack Eastern Wu for a while. In fact, the Jin Dynasty also had actions against Eastern Wu at the beginning, such as the Xiling Governor who rebelled against Eastern Wu. Xiling, also known as Yiling, is an important town in Jingzhou, and the Bu family is a famous family in Eastern Wu, and the impact of Bu Yan's surrender can be imagined.
4. Wu adopted a series of defensive measures militarily. After the fall of Shu, Cao Wei launched several attacks on Wu, but Wu successfully resisted. Militarily, Wu adopted the strategy of "advancing by land and water" and took advantage of the superiority of the navy and army to effectively strike at the enemy. At the same time, Wu also adopted the strategy of "fortifying the city and fortifying it", strengthened the construction of city defense, and effectively protected the territory of Wu.
5, Sima Yan is not too much of a retribution, let alone too enterprising, after reigning for more than ten years, the war to destroy Wu was launched, this is still during the period Sun Wu himself continued to die, so he gave Sima Yan the opportunity to destroy Sun Wu, otherwise, I am afraid I don't know when I will be able to unify the world. However, just eleven years after the Jin Dynasty unified the world, the famous Eight Kings Rebellion broke out in history, and after more than ten years of the Eight Kings Rebellion, the Western Jin Dynasty's national strength declined rapidly, and was finally destroyed by the Xiongnu.
6. Yanghu, who was the military governor of Jingzhou at the time, hurriedly sent troops to respond to Bu Xi, but Lu Kang, a famous general of Eastern Wu, led his troops to surround Bu Xi and reject Yang Hu outside. Although Yanghu was in a situation of attacking Lu Kang inside and outside, he was killed by Lu Kang, and the Battle of Xiling ended with the victory of Dongwu. This battle proved that Eastern Wu still had a strong strength, and to a great extent, it frustrated the confidence of the imperial court to destroy Wu, so in the future, even if Yanghu repeatedly wrote to ask for the destruction of Wu, he could not convince the imperial court.
To sum up, the reason why Wu was able to hold out for many years during the confrontation was mainly because it had a strong naval army and navy, correct strategy and tactics, the support and support of the people, and excellent generals and officials. The combination of these factors allowed the state of Wu to maintain stability and development during the confrontation.
