"Romance of the Three Kingdoms, Guan Yu Biography": So Quan Yin seduced Fang, Ren, Fang, and Ren made people welcome power. And Cao Gong sent Xu Huang to save Cao Ren, but Yu could not be overcome, and led the army to return. Quan had already taken possession of Jiangling, and yu shishi's wives were captured, and the Yu army was dispersed. Quan Shu will counterattack Yu, behead Yu and Zi Ping in Linfeng.
After Liu Bei, Zhuge Liang, Zhang Fei, Zhao Yun, Huang Zhong, and others entered Sichuan to fight, Jingzhou was very empty, and only Guan Yu was left with senior generals. Although Zhuge Liang gave Guan Yu the eight-character policy of "East and Sun Quan, North Reject Cao Cao" before leaving, it could ensure that Jingzhou was foolproof. However, in 219 AD, Liu Bei and others won the final victory in Hanzhong, and Guan Yu thought about hitting iron while it was hot and carrying out a major Northern Expedition.
He then raised an army from Jiangling, Jingzhou, besieged Cao Ren at Fancheng, Lü Chang at Xiangyang, and flooded the Forbidden Seventh Army, threatening Huaxia. However, due to the treachery of his allies Sun Quan, he and Cao Cao jointly attacked Guan Yu, cutting Guan Yu's back road, making it impossible for him to return home, and finally defeated Maicheng, and Yu Was killed in Linfeng.
Now, many people blame guan yu for not being the best person to sit in Jingzhou, because Guan Yu's interpersonal relations are too poor, which offends Sun Quan, causing Sun Quan and Cao Cao to unite together, and eventually lead to a different head. If Zhao Yun was allowed to guard Jingzhou, and Zhao Yun was a military general who took the overall situation into consideration, he would not easily offend Sun Quan, nor would he lose Jingzhou. Is that right?
Personally, I believe that even if Zhao Yun guards Jingzhou, he will not change the fact of losing Jingzhou, and analyzes the following from the three aspects of Sun Quan, Cao Cao, and Jingzhou.
Sun quan
Jingzhou (南郡) was not fought by Liu Bei on his own, but zhou Yu, the governor of Eastern Wu, led the Jiangdong army after a year of fighting, and "killed and wounded a lot" and injured many people, before driving Cao Ren away and taking Nan County. After Zhou Yu's death, the newly appointed Lu Su, in order to better resist Cao, proposed to Sun Quan to temporarily lend Jingzhou to Liu Bei, support Liu Bei, and jointly resist Cao Cao. As the old saying goes, "It is not difficult to borrow and repay, and it is not difficult to borrow again", but Liu Bei was the biggest "Lao Lai" in the Three Kingdoms period, and after borrowing Jingzhou, he never thought about returning it. Sun Quan was speechless about this, always thinking about how to take back Jingzhou, and made eighteen strategies.
In 215, sun Quan learned that Liu Bei had taken Yizhou, and after sending people to demand Jingzhou without success, he sent Lu Su, Lü Meng, Gan Ning and other generals to attack Jingzhou, which Guan Yu was defending. The two sides are fiercely fighting, and war is on the verge of breaking out. Finally, Liu Bei faced Cao Cao's threat and made a pact with Sun Quan to divide Jingzhou equally, that is, Jiangxia County, Changsha County, and Guiyang County in Jingzhou belonged to Sun Quan, and Nan County, Lingling County, and Wuling County in Jingzhou belonged to Liu Bei, which was called xiangshui demarcation.
However, for Sun Quan, just taking Jiangxia County, Changsha County, and Guiyang County was not satisfied, and what he wanted was the whole of Jingzhou, especially the rich Nan County. After Cao Cao sent people to contact Sun Quan, the two immediately hit it off, wanting to attack together and curb Guan Yu's development. So Sun Quan sent Lü Meng, dressed in white, to cross the river and raid Jingzhou.
Jingzhou
After 215 AD, Liu Bei and Sun Quan "demarcated the xiangshui boundary" and assigned Jiangxia County, Changsha County, and Guiyang County to Sun Quan, and the scope of Jingzhou under his control was greatly reduced, leaving only Nan County, Lingling County, and Wuling County. Cao Wei controlled the rich cities of Fancheng and Xiangyang. Therefore, at the junction of the three sides of Wei Shu and Wu, the jingzhou area controlled by Guan Yu had long since ceased to be dominant. If Guan Yu strictly implemented Zhuge Liang's eight-character policy, he might not be able to keep it. What's more, if Guan Yu takes the initiative to attack, the odds of winning are even smaller.
Cao Cao
Cao Cao had just been defeated in Hanzhong, and now Cao Ren of Fancheng was besieged by Guan Yu. He then quickly dispatched the Seventh Army of Yu Ban and Pound, but unfortunately guan Yu was flooded with the help of heavy water, and the entire army was destroyed. Cao Cao then sent a second reinforcement, Xu Huang, to temporarily contain Guan Yu's offensive. Even if Xu Huang followed in yu's footsteps, Cao Cao could still send a third reinforcement, and the third reinforcement, that is, Cao Cao led the army and personally went to war. Guan Yu was only a partial division, and it was difficult to resist Cao Cao's army.
The above analysis of the situation of Sun Quan, Jingzhou, and Cao Cao, the next analysis is that if Zhao Yunzhen guards Jingzhou, can he do better than Guan Yu? Can he ensure that Jingzhou is foolproof?
Zhao Yun did things in a down-to-earth manner, and without Guan Yu's "pride", he would not insult Sun Quan, refuse Sun Quan's proposal, and offend Sun Quan like Guan Yu. However, Zhao Yun could not offend Sun Quan, and Sun Quan and Cao Cao would not take the initiative to attack the "fat meat" of Jingzhou? I don't see it. Just think, you haven't offended the robber, but the robber may also find you, he is for money, he will not let you go because you are kind to others. This is also the reason for Guan Yu's Northern Expedition, his main purpose is to "attack instead of defend", and Zhuge Liang's Northern Expedition is a truth.
Therefore, even if the moderate Zhao Yun guarded Jingzhou, he did not offend Sun Quan, nor did he have the Northern Expedition, he might lose Jingzhou. If you don't hit someone, someone else may hit you. The distance between Jingzhou and Liu Bei's base camp, Yizhou, was too far, and the main forces of Jingzhou were all transferred away by Liu Bei, and the defense was empty. Therefore, if zhao yun is replaced by Zhao Yun shou Jingzhou, with his personal strength, he cannot change the end of Jingzhou's loss.
