Sun Quan promised to lend Nanjun to Liu Bei. In addition to his own pressure, there is also the intention of the so-called Dongwu strategist Lu Su, because Lu Su gave him a famous suggestion when Sun Quan just took over the Jiangdong regime. On the sofa, right? Strategy, which is equivalent to Shu Han's Longzhong confrontation strategy, is the highest development strategy of their respective regimes.
Sun Quan and Lu Su
Lu Su's strategy of lying on the couch for Sun Quan was seven years earlier than Zhuge Liang's long-term confrontation for Liu Bei. At the same time, Lu Su was the first recorded person who put forward the overall strategy of the group at the end of the Eastern Han Dynasty, and he was also the first person who said that it was impossible to revive the regime in the Eastern Han Dynasty. Lu Su told Sun Quan, who was only 19 years old, that he would set foot in Jiangdong to observe the situation in the world, take the opportunity to destroy Huang Zu, the satrap of Jiangxia, attack Liu Biao, and finally go west.
When Lu Su said this, it was 200 AD. At that time, the world situation was still unclear. Cao Cao is still fighting Guandu with Yuan Shao in the north. Jingzhou is occupied by Liu Biao and Yizhou is guarded by Liu Zhang. Sun Quan has just taken over Jiangdong, and there are many things facing domestic political stability, so he is too busy to attend to these. Therefore, it is too early for Lu Su to talk about this world strategy for Sun Quan.
However, Sun Quan did not forget Lu Su's strategy. When Lu Su was alive, Sun Quan basically listened to Lu Su's suggestions and strategies. For example, after stabilizing the domestic situation, Sun Quan once levied three taxes on Jiangxia County in Jingzhou, and like a couch, he killed Huang Zu, the Jiangxia satrap under Liu Biao, occupying half of Jiangxia County. Sun Quan wanted to seize Jingzhou, partly because of Lu Su's lying on his couch, and partly because he killed his father.
Sunerdai
Because Sun Quan's father, Sun Jian, was killed by Liu Biao's Howie behind his back, the revenge of killing his father was not * * *, while Cao Cao's father was brutally retaliated against Tao Qian after being killed by Tao Qian, and even used the massacre as a means of revenge, because filial piety was the first morality in the Han Dynasty and the basic moral quality that everyone must abide by. So did Cao Cao and Sun Quan, so Sun Quan vowed to slay the Jiangxia satrap.
In fact, Sun Quan still has an emperor's dream in his heart, an emperor's dream of unifying the world and making great achievements in the empire. However, Sun Quan's dream is hidden, unlike Cao Cao, who set an example with practical actions. Liu Bei talks about reviving the Han Dynasty every day. Everything Sun Quan did was to unify the world while ensuring the stability of Jiangdong regime. Sun Quan also has the ambition to unify the world.
Just as Sun Quan was preparing to continue to attack Jingzhou in the west, the situation in the world changed greatly in accordance with Lu Su's strategy of lying on his couch. In 208 AD, after pacifying the whole north, Cao Cao couldn't wait to aim his gun at the south. Soon, Cao Cao personally led the army to levy Liu Biao in Jingzhou, and Liu Biao died of illness. His second son, Liu Cong, became a shepherd in Jingzhou, and Liu Cong surrendered to Cao Cao under the coercion of his Jingzhou strongmen. Because of this sudden political situation, Lu Su and Sun Quan were anxious to know the situation in Jingzhou and change their strategies.
Sun Quan and Liu Bei
So, shortly after Liu Biao died, Lu Su went to Jingzhou. Lu Su must have discussed the political situation with Sun Quan before leaving Jiangdong. Without Sun Quan's consent, it is impossible for Lu Su to express his political intention of forming an alliance with Liu Bei while meeting with him. This is a pre-determined idea of Sun Quan and Lu Su, so after Cao Cao went south to Jingzhou, his strategy changed at this time: to form an alliance with Liu Bei, * * *.
Lu Su's tactics influenced Sun Quan from beginning to end, including Battle of Red Cliffs's former Sun Quan's reluctance to surrender to Cao Cao. It is largely the temptation of Lu Su. It is better to be the master of the independent party than to be the puppet of Cao Cao. At the same time, Sun Quan's dream of emperor forced him not to surrender to Cao Cao, so the alliance between Sun Liu and Sun Quan was actually put forward and led by Sun Quan.
Including Sun Quan, who was painstakingly managed by Zhou Yu for one year, lent Nanjun to Liu Bei, all of which had Lu Su's intention. Lu Su persuaded Liu Bei of Sun Quan Alliance to confront Cao Cao. On the other hand, in order to reduce the military pressure, on the border of Wei Wu, thousands of kilometers from Yangzhou to Jingzhou, only Sun Quan faced the military pressure of Cao Cao. Because Liu Bei's territory is in the four counties of Jingnan, and it is not adjacent to Cao Cao's territory, how can Liu Bei come over?
Liu Bei married Sun Quanmei and borrowed Jingzhou.
There is only one way, that is, lend Nanjun to Liu Bei. As long as Nanjun lends Liu Bei, Liu Bei will meet Cao Wei in Jingzhou. Then Liu Bei will be in charge of Jingzhou's military defense, and Sun Quan can reduce the military pressure. Therefore, Lu Su is also very supportive of the Sun-Liu Alliance, and Lu Su is also the only staunch supporter of the Sun-Liu Alliance in Soochow.
When Lu Su was around, Sun Quan still attached great importance to Lu Su, and most of them listened to Lu Su's alliance with Liu Bei. Unexpectedly, Liu Bei did not return Nanjun after winning Yizhou, so Sun Quan sent troops to capture the four counties in Jingnan. Because Cao Cao was fighting in Hanzhong, Liu Bei felt the crisis, so he quickly made peace with Sun Quan and cut Changsha County and Guiyang County to Sun Quan instead of Nanjun borrowed by Liu Bei, and then Sun Quan and Liu Bei were still there.
Although Sun Quan lent Nanjun half of Jiangxia County+Changsha County+Guiyang County, Sun Quan was still not satisfied. He traded 1 county for 2.5 counties, but Sun Quan was still not satisfied. It can only show that Nanjun is far more important to Sun Quan than half of Jiangxia County+Changsha County+Guiyang County.
Jingzhou Qi Jun
In addition, Jingzhou Nanjun has natural convenience for Jiangdong regime. Sun Quan's Jiangdong regime used to guard against Cao Cao in the north. The Yangtze River can guard against the north, but it can't guard against Jingzhou Nanjun, which is also in the Yangtze River basin. If an enemy goes down the river from Nanjun, it will be the only weakness and fate of Sun Quan's regime. For the absolute stability of the regime, Sun Quan has always had the idea of taking Jingzhou Nanjun.
Although Sun Quan was sold to Lu Su for face when Lu Su was alive, Sun Quan's consideration was always from a political perspective and interests. Even though Lu Su was alive, Sun Quan had the idea of taking Nanjun, but he didn't have the idea of northern expedition to Hefei. For Hefei, Sun Quan didn't want it, but he didn't have the ability to want it, or even if it was shot down, he couldn't keep it, because Hefei was built in the north, far from the Yangtze River, and Sun Quan's water army just slammed in the water and couldn't land at all.
Map of Jingzhou in Three Kingdoms
Since it is difficult to break through in the north, Sun Quan began to focus on the west, with the sea in the east and Cao Wei in the north. The south has been occupied by Sun Quan all the way to Jiaozhou, and only Nanjun in the west is the only place that Sun Quan can seize, which is also a strategic breakthrough for Sun Quan. In fact, when Lu Su was here, Sun Quan began to plan the strategy of how to seize Nanjun.
Because Sun Quan sent people to reach a settlement with Cao Cao in AD 2 17, and sent a surname Xu Xiang to see Cao Cao, asking him to surrender. At the same time, the two sides formed a political marriage. The reason why Sun Quan did this was to create political advantages for the capture of Jingzhou, because if Sun Quan broke with Liu Bei, he would definitely break with Liu Bei. Sun Quan could not fight on two fronts, but only one side and the other. Sun Quan's strong will to seize the South Army in Jingzhou never let go of Liu Bei's first battle, and could not stop Lu Su at all, so whether Lu Su is alive or not, Sun Quan will seize Jingzhou.
