After Cao Rui came to power, he attacked Liao three times in the sixth year of Taihe (232), the first year of Jingchu (237), and the second year of Jingchu (238), and finally destroyed the Gongsun clan. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ。 :。

Three times to cut Liao

In the sixth year of Taihe (232), Cao Rui sent the Yanyi general Tian Yu to lead the Qingzhou troops along the sea route, and Youzhou Assassin Shi Wang Xiong led the Youzhou troops to attack Liaodong by land.

During the Taihe period, because Zhuge Liang of Shu Han and Sun Quan of Eastern Wu sent troops to the Northern Expedition for many years, Cao Rui faced great defensive pressure, so at this time, although he was very dissatisfied with Gongsun Yuan's collusion with foreign enemies, and once sent troops to fight, but considering the overall situation, he finally gave up this battle. Later, Gongsun Yuan betrayed Sun Quan and expressed his loyalty to Cao Wei, and the relationship between Liaodong and Cao Wei eased again.

However, after Gongsun Yuan's attitude towards Cao Wei's envoy was very bad, Cao Rui regained the heart of Liao, and took the excellent Biqiu Jian as the history of Youzhou, Biqiu Jian once again proposed Cao Rui to level Liao, which was recognized by Cao Rui, but at that time Liaodong had broken off relations with Wu State, so Cao Rui saluted first and then sent Biqiu Jian to lead the army to recruit Gongsun Yuan to the court.

In the first year of the early Jing Dynasty (237), the second expedition of Biqiu Jian and others can be said to have laid the foundation for the third expedition to Liao. First of all, the first priority of this military operation was to recruit Gongsun Yuan into the court, and military action would only be taken if Gongsun Yuan refused, and as long as Gongsun Yuan refused to enter the court, it was actually equivalent to declaring war on Cao Wei, which also gave Cao Wei an excuse and reason to attack.

In terms of troops, Biqiu Jian's troops are only the soldiers of Youzhou and a state, and the troops of the first expedition to Liao also include Qingzhou soldiers, this time it can be said that the strength is not very strong, before Biqiu Jian sent troops, Guanglu doctor Wei Zhen directly said that Biqiu Jian wanted to level Liao with a state army is very arrogant, so it is not an accident to say that Biqiu Jian's defeat this time is not an accident, even if there is no impact of heavy rain, it is difficult for Youzhou's troops alone to defeat Liaodong, which is firmly defended by the side of security.

Cao Rui himself could not have imagined this, otherwise he would not have dispatched the troops of the two states for the first time in the invasion of Liao, at that time, Cao Rui for Biqiu Jian's military action may be to 'force' Gongsun Yuan to express his position, if Gongsun Yuan is indeed reversed, Biqiu Jian can destroy Liao with a state of troops is the best, and if he can't go back, he will mobilize the army and fight again, so Biqiu Jian did not record being punished after the defeat of the army, because Cao Rui's basic purpose has been achieved.

In the second year of the early Jing Dynasty (238), Cao Rui sent Sima Yi to attack Liao for the third time after he was ready, and this battle was the real battle to destroy Liao. In terms of the external situation, the threat of Shu Han and Sun Wu to Cao Wei had been reduced, and Cao Wei was able to free up enough forces to crusade against Liaodong; In terms of strength, Sima Yi led 40,000 'elite' troops from the center alone, and later Youzhou Assassin Shi Biqiu Jian may also lead the troops to participate in the war, and the overall strength is already higher than the first expedition to Liao, and Gongsun Yuan has little hope in the face of the troops in the two states, not to mention that there are now Sima Yi these 'fine' British generals to lead.

Therefore, the outcome of the third expedition to Liao was actually decided when Cao Rui sent Sima Yi, in the final analysis, Gongsun Yuan was only in Liaodong, and his overall strength was at the county level, at most at the level of a small state, and the gap between Sima Yi's army was too big, and Cao Wei was even more of a heaven and a place, Gongsun Yuan should not have delusions from the beginning.

Sima Yi pacified Liaodong, we can intuitively find that Sima Yi's use of troops is like a god, but we need to understand the planning and preparation of Emperor Cao Rui of the Ming Dynasty at that time, it was indeed Sima Yi who directly destroyed Liao, but it was Cao Rui who really destroyed Liao.

The impact of the Liaoning

In history, Sima Yi's pacification of Liaodong had a huge impact, first of all, this greatly strengthened Cao Wei's influence on the surrounding countries, especially in Northeast Asia, and secondly, this battle greatly improved Sima Yi's prestige, which was one of Sima Yi's important military exploits in the future, and finally it was a small problem, after the demise of the Gongsun clan, some small countries that had been suppressed were stupid 'wanting', but in front of the powerful Cao Wei, these are small things.

After Cao Wei pacified Liaodong, it had an immediate and significant impact on Northeast Asia, because whether countries wanted to compete for hegemony or allies, the object of consideration was changed from Gongsun Yuan to Wei. Among them, the Evil Horse Tai State with internal and external pressure is the most active, so Wei also named Bei Mihu as the pro-Wei Wa King, fake gold seal purple ribbon, together with the ambassador Nansheng Mi also won the rate of good Zhonglang general, fake silver seal green ribbon. The Sino-Japanese foreign 'exchange' from Japan to the belt side by sea and then to the Central Plains by land was opened again. After Himiko's death, there was a civil 'strife', and the result was decided by Wei Ting, and the dispute was settled by Yi He's succession, which shows the great influence of Wei. (Note 1)

And Sima Yi himself was very 'outstanding' in this battle, and he was extremely flexible in using troops, and this battle also became a classic example and was cited by later generations in the art of war. After the war, Sima Yi's own prestige in Cao Wei also reached a new height, and soon Cao Rui made him and Cao Shuang become the ministers of Tuogu, and the two jointly assisted the new emperor Cao Fang in managing the government. The Battle of Annihilation of Liao and the 'Rebellion' of Pingmengda were considered by later events to be one of Sima Yi's major military achievements.

Originally, the battle to destroy Liao was Cao Rui's own performance, and the preparation and planning work in the early stage was actually done by Cao Rui, Sima Yi actually only took the head in the end, if Cao Rui did not want to ensure that this operation must be successful, it would be difficult to get this opportunity to send troops with Sima Yi's prestige and status.

After the destruction of Liao, everyone in the world knew Sima Yi, but Cao Rui was forgotten by most people, which means that Cao Rui made a wedding dress for Sima Yi. But how to say it? With Sima Yi's performance in this battle, especially in the future, Sima Yi's status is also above Cao Rui, this result is actually not unreasonable.

In addition to the good influence, there are also bad influences, because the Gongsun clan has been relatively strong in the northeast, so after the Gongsun clan was eliminated, some small countries began to be stupid 'desire' to move, which was represented by Goguryeo, and later repeatedly invaded the Wei state, but at that time Cao Wei was not easy to bully, as a retaliation, Youzhou assassin Shi Biqiu Jian twice crusaded against Goguryeo, almost destroyed the country.

At that time, Gongsun Yuan and Zhuge Liang, Sun Quan and Kirbineng could be said to be the four main enemies faced by Cao Rui, before Gongsun Yuan, Zhuge Liang had died of illness, Kirbineng was assassinated, only Sun Quan was still alive and Cao Wei was left to make trouble, Shu Han has not been much after Zhuge Liang's death.

And Cao Rui himself was still very young at the time, according to the normal situation, it was not impossible for him to survive Sun Quan, and then destroy Shu Han and Sun Wu, but how to say it, if he didn't die, he wouldn't die, but the young Cao Rui played himself to death.
