Sentence / Kodama
During Sun Ce's era, Jiangdong had always played the role of a vassal of the Han Dynasty, expanding its territory under the cover of being a "loyal minister". After the Battle of Chibi, Sun Quan's goal was very clear, that is, in the context of the irrevivalability of the Han Dynasty, he annexed Jingyi to the west, opened up the Yangtze River defense line, established the imperial industry, confronted Cao Cao across the river in the way of the Northern and Southern Dynasties, and then waited for the opportunity to go on a northern expedition to establish the cause of Emperor Gao. In this process, all actions must serve this goal, including making appropriate compromises to Liu Bei.
To be honest, the alliance between Liu Bei and Jiangdong is an accident, and it is not taken by Liu Bei's side as Zhuge Liang planned in "Longzhong Pair".
In August of the thirteenth year of Jian'an (208), Liu Biao died of illness, and the news reached Jiangdong, Lu Su immediately asked Sun Quan to send an envoy to Jingzhou in the name of mourning, and then adjust the relationship between Jiangdong and Jingzhou according to the actual situation of Jingzhou: if Liu Bei and Liu Biao's two sons worked together, then they would form an alliance with Jingzhou, and if the three parties were separated, then they would find a way to take Jingzhou.
In Lu Su's planning, taking Jingzhou is a must, depending on how to play the cards.
It's just that when Lu Su walked to Xiakou, he learned the news of Cao Cao's southern expedition, and when he arrived in Nanjun, Liu Cong had surrendered, and after learning the news of Liu Bei's southward departure, Lu Su immediately decided to chase Liu Bei and saw Liu Bei in Dangyang.
At this time, Lu Su's business trip plan had been completely disrupted by the drastic situation, and all he could do was to improvise and maximize Jiangdong's interests in the chaos as much as possible. After catching up with Liu Bei, Lu Su expressed his intention to cooperate with Liu Bei in order to build a Sun-Liu community to fight against Cao's army.
Of course, Liu Bei couldn't ask for it, because the Sun-Liu Alliance was a life-saving straw for him in a desperate situation, so there was a link for Zhuge Liang to send Jiangdong.
As for why Lu Su insisted on forming an alliance with Liu Bei in distress, it was because Jiangdong at this time was a voice of surrender in the face of the might of Cao's army, especially the civilian system represented by Zhang Zhao, and Lu Su needed to introduce Liu Bei, a staunch anti-Cao faction, to strengthen the will to resist Cao within Eastern Wu. Of course, Liu Bei and Liu Qi also have a certain surplus value for Jiangdong, and their remnants can enhance the probability of victory for Eastern Wu.
After negotiating with Liu Bei, Lu Su suggested that Liu Bei enter Fankou, ensuring that the Jiangdong forces could enter Jiangxia from Fankou and fight deep into Jingzhou. After that, Liu Bei played a considerable role in the reason why Zhou Yu was able to grasp the initiative of the war and introduce the battlefield into Jingzhou.
Next is the plot of the Battle of Chibi, and Liu Bei's role in it is the role of a collaborator.
Please note that since the beginning of the Sun-Liu Alliance, the relationship between the two sides has been established: Sun Quan is the protagonist, Liu Bei is the supporting role, and Liu Bei's group cooperates with Jiangdong's operation of the Yangtze River defense line while undertaking a certain anti-Cao heavy task, as long as Liu Bei has a slightly uncontrolled situation to challenge the authority of the protagonist, then Sun Quan's attack will definitely be arranged immediately.
After the Battle of Chibi, Liu Bei took the four counties of Wuling, Changsha, Guiyang, and Lingling, Sun Quan occupied most of Jiangxia County and Nan County, and Cao Cao only retained control of Nanyang County and part of Nan County.
Jingzhou was divided between the forces of Cao, Sun, and Liu.
Although Liu Bei occupied the four counties in the south of the Yangtze River, his living conditions did not change because of this, because Cao Cao still controlled the northern world aggressively, and Sun Quan not only had a strong base in Yangzhou but also firmly controlled the important strongholds along the Yangtze River after the Battle of Chibi, Yiling, Jiangling, Baqiu, and Lukou strategic points were under the control of the Wu army.
In order to break the game, Liu Bei first played the card of Liu Qi and listed Liu Qi as the assassin of Jingzhou, so as to siphon the elite of Jingxiang and transfer Liu Biao's talent pool to his own name. After Liu Qi died of illness, Liu Bei took the Jingzhou pastor under the recommendation of the Jingxiang clan.
After finishing it, Liu Bei personally went to Jingkou to ask Sun Quan for important places, and asked Sun Quan to give him Jiangling and other places.
At that time, Jiangdong was divided into two completely different factions on Liu Bei's card: Zhou Yu and Lü Fan were staunch in the anti-Liu faction, believing that Liu Bei had a heroic posture and should be eliminated in advance, and Lu Su supported the continued extraction of Liu Bei's surplus value and an alliance against Cao Cao in the north.
In order to convince Sun Quan, Zhou Yu provided a very clear plan for expansion: first Jingzhou, then Yizhou, then Hanzhong, and then an alliance with Ma Chao in Liangzhou, and sent troops from Qinchuan and Wanluo to the Northern Expedition, plus Jianghuai, and Eastern Wu would have three forward positions in the north by then.
Moreover, Zhou Yu also suggested that Sun Quan should send troops to guard against Liu Bei, who was stationed in the public security.
Sun Quan agreed to this plan at the time, but Zhou Yu died of illness in Baqiu on the way back to Jiangling, making this grand blueprint lose the possibility of landing.
When Lu Su replaced Zhou Yu's position in Jiangdong, history changed course, and at Lu Su's suggestion, Sun Quan agreed to continue the alliance with Liu Bei. At the same time, Sun Quan also married his sister to Liu Bei, and continued to consolidate the alliance between the two sides by marriage.

It can be said that this decision was Sun Quan's most rational choice at that time, and even Cao Cao was stunned after learning of Sun Quan's decision, and lost confidence in opening up Jiangnan in his heart.
The reason why Sun Quan is also a hero in troubled times is because he knows how to make trade-offs and knows the truth of sacrificing temporary interests to serve the ultimate goal.
It was over, Sun Quan asked Lu Su to move from Jiangling to Lukou, and gave Nanjun to Liu Bei, Liu Bei took Guan Yu as the Taishou of Xiangyang, General Dangkou, stationed in Jiangbei, and Zhang Fei as the Taishou of Yidu, Fengxin Tinghou, stationed in Nanjun.
Having controlled the Yangtze River defense line from the Three Gorges to Jiangdong section, Liu Bei has changed the previous completely passive situation, and there is room to break through to the north and west.
The reason why Sun Quan chose to continue to ally with Liu Bei was because after Zhou Yu's death, Sun Quan did not have a good general to integrate the resources of the Yangtze River defense line and land the imperial industry, and more importantly, the lack of Eastern Wu's own strength.
First of all, there is a serious problem of Yamagoe in Koto. Since Sun Quan took over Jiangdong, he has been dealing with the internal Shanyue problem, and for this reason, he also missed the best opportunity to get involved in Jingzhou during Liu Biao's serious illness. In the case that the Shanyue problem has not been eradicated, Eastern Wu does not have the extra troops to further develop Jingzhou and Yizhou, and in addition, it is necessary to operate military towns along the Yangtze River and strengthen the defense of the Jianghuai front, and the limited forces of Eastern Wu cannot support its multi-front operations, not to mention Cao Cao, a strong enemy.
Even Jingzhou next door, Sun Quan can't guarantee to swallow it. As we all know, Jingzhou and Jiangdong belong to a feud, fighting for many years, and Sun Quan's atrocities in the slaughter of the city after conquering Jiangxia in the thirteenth year of Jian'an (208) have left a shadow on the people of Jingzhou, and the people of Jingzhou are psychologically rejecting Sun Quan.
And Liu Bei is different, after eight years of deep cultivation in Jingzhou, he already has a certain prestige, and the people of Jingzhou followed Liu Bei to flee when Cao's army went south. At the same time, Liu Bei also captured the hearts of Jingxiang's elites by pulling Zhuge Liang into the team. Coupled with Liu Bei's further integration of Jingzhou's resources after the Battle of Chibi, Sun Quan could not replace Liu Bei's position in Jingzhou for a while, so it was better to continue to use Liu Bei's prestige in Jingzhou and let him share the pressure from Jiangbei's Cao army for Jiangdong.
In addition, at this time, Jiangdong was also seriously unstable. After Sun Ce crossed the river into Jiangdong, the Sun clan was labeled as an invader, and the Jiangdong clan was seriously uncooperative with him, and even repeatedly encouraged Sun Quan to surrender after Cao Cao occupied Jingzhou, and the Jiangdong clan believed that Sun Quan could not represent their own interests and could not protect their property.
Even if Sun Quan won the Battle of Chibi, but only stabilized the Jiangdong clan for a while, how to realize the convergence of the Huaisi group and the Jiangdong clan, Sun Quan still has a lot of work to do, and this will definitely take time to digest. Among the Three Kingdoms, the reason why Sun Quan was the latest to be emperor was because the internal Shanyue issue was not properly handled, and the Jiangdongization of Sun Wu's regime was not realized.
In other words, it is impossible for Sun Quan to put his hand into Jingzhou without a stable interior, which will only lead to his poor operation in Jingzhou and Yangzhou.
Looking at it this way, it is very understandable that Sun Quan ceded Nanjun to Liu Bei, that is, Liu Bei used his advantages in Jingzhou to share the pressure from Cao's army in Jiangbei, and concentrate on managing the Jianghuai defense line by himself, while dealing with Yangzhou's internal problems.
Why Liu Bei cousin Sun Quan is the general of the chariot cavalry and leads the Xuzhou pastor is a confirmation of the division of labor between the two sides: Sun Quan runs Xuzhou, Liu Bei runs Jingzhou, and Sun Liu destroys Cao from two directions.
Sun Liu's division of labor is clear Source/Network
But at this time, Sun Quan is still a proper protagonist and belongs to the leader, which can be seen from the labels on both sides: Liu Bei is General Zuo, Sun Quan is the general of the chariot cavalry, and the general of the chariot cavalry is traditionally above the general Zuo.
In other words, although Liu Bei at this time expanded his living space under the banner of Lian Wu Kangcao, the challenge was still very big.
In Zhuge Liang's words: "The lord was in the public security at the time, there was pressure from Sun Quan in the east, the powerful Cao Cao in the north, and there was a spy Madame Sun lying beside him, and he was extremely anxious." ”
Pang Tong is also deeply worried about this situation: "Sun Wu in the east, Qiang Cao in the north, and Jingzhou has limited resources, so it is difficult to achieve great things." ”
At the same time, Jiaozhou was also Sun Quan's position to restrain Liu Bei.
At this time, taking Yizhou to the west to expand the living space has become Liu Bei's must choice, why Liu Bei is strongly opposed to Sun Quan's move to send Sun Yu to open up Yizhou, and even does not hesitate to enter the mountains for the sake of the coward, the reason is here.
It just so happened that Liu Zhang of Yizhou sent a signal to Liu Bei to enter Shu, and Liu Bei couldn't ask for it.
But when Liu Bei entered Shu and became a guest, the balance was broken, and when Liu Bei's identity in the Sun-Liu alliance gradually transitioned from a supporting role to a protagonist, Jingzhou once again became a powder keg.
The battle between Sun and Liu is inevitable.
