Dongwu was ridiculed by the group as a Jiangdong rat because he crossed the river in white to seize Jingzhou and captured Guan Yu, thinking that Dongwu was a proper villain who backstabbed his allies.
In fact, there are no eternal friends, only eternal interests, this wise saying is common in ancient and modern times, and it is even more vividly reflected between Liu Bei's Shuhan Group and Sun Quan's Soochow Group.
The alliance between Sun and Liu was very complicated, the alliance between the two sides originated in Jingzhou, the contradictions also originated in Jingzhou, and the rupture also originated in Jingzhou.
The importance of Jingzhou's geographical location and prosperity is self-evident in the north-south hegemony during the Three Kingdoms period, Cao Cao can dominate the world, Liu Bei can gain a foothold and become a full momentum, and for the downstream of Eastern Wu, Jingzhou, which is in the middle reaches of the river, is like a sword hanging over his head, and he will want to get it and feel at ease.
It was around Jingzhou that the two major forces of Liu Bei and Sun Quan staged a wonderful love-hate relationship.
After Cao Cao's army went south, Jingzhou surrendered without a fight, Liu Bei led the remnants of the army to Liu Qi, who was only left in Jiangxia, and when the fall was imminent, it was the Eastern Wu who defeated Cao Cao in the Battle of Chibi, although the Eastern Wu had its own plans, but it was undoubtedly to save Liu Bei.
Later, Sun Quan, at the suggestion of Lu Su, lent Jingzhou to Liu Bei, who had no place to live, including Zhou Yu, who took a year to capture Nanjun, which was guarded by Cao Ren, and agreed to return it after taking Yizhou and having land. This act of sending charcoal in the snow shocked Cao Cao's jaw.
Later (Liu) Beiyi saw (Sun) Quan in Beijing and begged the governor of Jingzhou, but (Lu) Su persuaded the right to borrow it, and rejected Cao Gong. Cao Gongwen has the right to prepare the land industry, write a book, and write on the ground.
Since the alliance between Sun and Liu, it has been the unilateral contribution and more responsibility of Eastern Wu, when Cao Cao attacked Eastern Wu, Eastern Wu told Liu Bei urgently, but Liu Bei could not provide any help.
Moreover, it is easy to invite God and it is difficult to send God, but it is easy to take it back when Jingzhou is lent out, but it is difficult. After Liu Bei captured Yizhou, Sun Quan wanted to return to Jingzhou, but Liu Bei responded in a trick and said".I plan Liangzhou, Liangzhou is fixed, and it is all about Jingzhou and Wu Er. When I get Liangzhou, I'll return all of Jingzhou to you.
It has been loaned out for five years, in the face of Liu Bei's breach of contract, the uncle can bear it and the aunt can't bear it, Sun Quan directly sent officials to the three southern counties of Jingzhou, but was expelled by Guan Yu who guarded Jingzhou, Sun Quan finally couldn't bear it anymore, if you don't pay it back, I will go and grab it back, and decisively sent Lu Meng to attack Changsha, Guiyang, and Lingling three counties.
After the two sides tore their faces, Liu Bei personally led 50,000 troops out of Shu to prepare for a fight, at this time Cao Cao marched into Hanzhong, Shu ** moved, Liu Bei then negotiated peace with Sun Quan, returned Jingzhou, Jiangxia, Changsha, Guiyang to Eastern Wu, still occupy Nanjun, Lingling, Wuling.
And Shu Han's second-in-command Guan Yu was not good at handling the relationship with Dongwu during the period of guarding Jingzhou, so the two sides had constant small frictions.
Later, the loyal Lu Su couldn't help but reprimand Guan Yu at the single knife meeting: "The country originally borrowed the Qing family with land, and the Qing family's army was defeated from afar, so there was no reason for it." Now that he has gained the state, he has no intention of returning it, but he asks for three counties, and he does not obey his orders. "When you were at the end of your rope, you said that you came to borrow Jingzhou, but now you have a place to live but you don't mean to return it, we take a step back and ask for three counties, and you still don't agree.
Shu Han responded, "The husband of the land, but the ear of virtue, how often there is!" Guan Yu also took care of face, and only said, "This is a national affair, how do people know!" ”
The two sides have their own arguments, but in general, the Shu Han side is reasonable.
However, Soochow has always been focused on maintaining reconciliation between the two sides, and only Lu Meng".Knowing Yu Xiaoxiong, having a heart for both, and living in the upper class of the country, it is difficult for it to last long. And Yu Junchen, with his deceitful power, is repeated, and he can't be treated with his heart. Thinking that it should not be tolerated again and again, Sun Quan suggested that Sun Quan find an opportunity to recapture Jingzhou, but Sun Quan not only did not adopt it, but also very relieved to transfer most of his troops from the border between the two sides to the northern expedition to Cao Cao. However, Guan Yu has always been guarding against the capture of Jingzhou by Eastern Wu, and when he launched the Battle of Xiangfan, he also left a large number of troops to defend Jingzhou.
Therefore, the two sides are allies on the surface, but in fact they have their own thoughts, but Soochow has maintained restraint for a long time.
And Guan Yu is proud, has always looked down on Eastern Wu, often has a heart of insult, and has no respect for Sun Quan, in the face of his request to marry his sons and daughters, not only refused but also humiliated that the tiger girl had to marry a dog, "Dictionary" also recorded that Guan Yu in the attack on Fancheng, because of the suspicion that Sun Quan's reinforcements were slow and scolded "Gang Zi Daer", and said that after capturing Fancheng, Sun Quan could be destroyed. After Sun Quan learned about it, he pretended to write a letter to apologize to Guan Yu, but he already hated Guan Yu in his heart.
As a result, the contradiction between the two sides was completely intensified, and Guan Yu's main force went north to give Dongwu an opportunity, so Dongwu decisively crossed the river in white clothes and took Jingzhou in one fell swoop and was captured and killed Guan Yu.
However, from a political point of view and the actual situation of the allies of both sides, it is difficult to put all the charges on Dongwu, although Jingzhou is not Liu Bei's nor Sun Quan, but Liu Bei was at the end of his rope It was Sun Quan who pulled him, and Liu Bei said that he was temporarily borrowing Jingzhou, but he regretted it afterwards and did not admit it, and in any case, he had lost morally first. Later, if Cao Cao hadn't entered Hanzhong, the Sun and Liu families would have broken up and fought earlier.
