Guan Yu's loss of Jingzhou can be said to be the biggest pain in the hearts of Shu Han fans, because since then, Shu Han's strength has been greatly reduced, and he only occupies the land of one state, and can no longer compete for the world. Don't look at Zhuge Liang's Northern Expedition and Jiang Wei's Northern Expedition, but in fact, there is no chance of victory at all, because the gap between the national strength of Wei and Shu is too big. It can be said that since the loss of Jingzhou, Shu Han has lost the opportunity to dominate the world!
Everyone realized the importance of Jingzhou to Shu Han, so everyone wondered, if another person replaced Guan Yu and let Zhang Fei, Zhao Yun or Wei Yan go to guard Jingzhou, could they hold it?
This kind of thinking is very reasonable, after all, Guan Yu gives people the feeling of being very proud, since he can't keep it, then change a few people who are not so arrogant, maybe they can do a good job of relations with Sun Quan and guard Jingzhou? But in fact, this kind of thinking is only an ideal state, and does not consider reality, if according to reality, no matter who goes to guard Jingzhou, it cannot be kept, unless Pang Tong is still alive!
So why is it that Jingzhou must not be able to hold it? In fact, the main reason is below!
Many people attribute Sun Quan's sneak attack on Jingzhou to Guan Yu's poor temper and anger Sun Quan, but in fact this view is a bit superficial. It is true that Guan Yu is indeed arrogant, and in the face of Sun Quan's courtship, shouting out the words "Wuhu's daughter marrying a dog" is indeed inappropriate, but this matter is not enough to be the reason for the two countries to go to war! The reason why Sun Quan insisted on sneaking into Jingzhou was not because of his bad relationship with Guan Yu, but because the strength of the Shu Han clique was rapidly expanding, threatening the safety of Eastern Wu!
After the Battle of Chibi, Cao Cao occupied Nanyang Commandery, Liu Bei occupied the four counties of Jingnan, and Sun Quan occupied Nan County and Jiangxia County, and it seems that Liu Bei's clique occupied the largest territory. However, Liu Bei's territory has a big shortcoming, that is, he and Cao Cao are separated by Sun Quan, that is to say, Sun Quan's Nan County is actually between Cao Cao and Liu Bei, and Liu Bei's territory is all inland areas, relatively poor, and the development value is not high, on the contrary, Nan County can not only connect Eastern Wu and Cao Wei, but also connect Yizhou, which is a treasure land, so Liu Bei suggested to Sun Quan that Nan County be lent to him, and he helped Sun Quan resist Cao Cao.
At that time, Although Eastern Wu won a great victory in the Battle of Chibi, the overall strength was not enough to compete with Cao Cao, the battle line in contact with Cao Jun was too long, it was easy to be broken by Cao Jun, and Liu Bei's strength at that time was not very strong, and the threat to Eastern Wu was less than Cao Cao,So Sun Quan directly lent Nan County to Liu Bei. It was precisely because of the acquisition of Nan County, Liu Bei's strength rapidly expanded, and he directly used this as a springboard to capture Yizhou and become a prince sitting on two major states, and his strength was not inferior to Sun Quan. So at this time, Sun Quan saw the crisis and felt that Liu Bei's clique might threaten him, so he asked Liu Bei to return Nan County to him. Liu Bei was naturally unwilling, and the meat he ate had a reason to spit it out, so the contradictions between the two sides intensified!
Sun Quan directly ordered Lu Su to attack Jingzhou, Guan Yu sent troops to confront Lu Su, Liu Bei also brought 50,000 soldiers and horses from Yizhou, to fight with Sun Quan, the big war was about to break out, as a result, at this time Cao Jun sent troops to Hanzhong, which surprised Liu Bei, so the Xiangshui Alliance appeared, Liu Bei ceded three counties to Sun Quan, in exchange for peace with Eastern Wu, and Sun Quan of Nan County did not return. In this conflict, Eastern Wu took advantage of the situation, and the two sides temporarily returned to peace, but soon after, Sun Quan was once again moved, and the reason why he was moved was because Liu Bei defeated Cao Cao in Hanzhong!
Cao Cao's strength does not need to be repeated, Liu Bei was able to defeat Cao Cao, which shows how powerful his strength is! More importantly, Guan Yu had a water army in his hands, and they could go down the river and attack Eastern Wu, so it seemed that Shu Han's threat to Eastern Wu was actually greater than That of Cao Wei! And this point is ignored by many people, everyone looks at the problem, always used to stand in the perspective of Shu Han or Cao Wei, if you stand in the perspective of Eastern Wu, you will find that the Liu Bei clique during the Battle of Xiangfan, the strength is too strong, the threat to Eastern Wu is greater, who knows if Liu Bei will suddenly change strategy and take Eastern Wu first? Sun Quan dared to pin the country's security on Liu Bei? How can it be? Therefore, after Liu Bei won the Battle of Hanzhong, Sun Quan would definitely plot against Jingzhou, because Guan Yu's water army was a very great threat to Eastern Wu!
Sun Quan always kept Jingzhou in mind, and the strategy of the Shu Han clique was to go north from Yizhou and Jingzhou at the same time, so as long as a certain time came, Jingzhou would send troops to the Northern Expedition, which could not be changed, whether it was Guan Yu, or Zhang Fei, Zhao Yun or Wei Yan, when the time came, they must send troops to the Northern Expedition, and as long as they moved, Sun Quan would definitely sneak into Jingzhou! Therefore, even if Zhang Fei, Zhao Yun or Wei Yan were to guard Jingzhou, it would be impossible to defend!
If you want to defend Jingzhou, there is actually only one way, that is, Pang Tong is not dead! This is also Liu Bei's initial strategic consideration, when Liu Bei attacked Yizhou, the reason why he only took Pang Tong and not Zhuge Liang, in fact, was to let Zhuge Liang assist Guan Yu in guarding Jingzhou, if Pang Tong did not die, then Guan Yu sent troops to the Northern Expedition, Zhuge Liang must have stayed in Jingzhou to guard, with Zhuge Liang in Jingzhou, Sun Quan could not defeat Jingzhou, only in this way, Jingzhou could not be lost!
epilogue
On the whole, if Guan Yu is replaced by Zhang Fei, Zhao Yun or Wei Yan, in fact, he will not be able to defend Jingzhou, because Sun Quan has been thinking about Jingzhou, as long as Jingzhou is northern, he will come to attack Jingzhou! In fact, only if Pang Tong was alive, Jingzhou could be defended. Because Pang Tong was alive, Zhuge Liang would stay in Jingzhou and help guard Jingzhou, in this case, even if Sun Quan sneaked into Jingzhou, it would be difficult to defeat Jingzhou!
