The Battle of Yiling was ostensibly a revenge war launched by Liu Bei, but in fact it was the last let-off of Liu Bei's political career, Liu Bei wanted to take advantage of the last opportunity of his life to provide a good environment for the development of the regime he had established, and under the banner of revenge for Guan Yu, he wanted to retake Jingzhou and expand the strategic depth and political prospects of Shu Han.
Jingzhou for Shu Han, is the lifeblood of development, without Jingzhou, Shu Han can only be a corner of peace, losing the capital to compete for the world, Liu Bei will never allow Jingzhou to be lost, even if at the risk of Cao Wei's tiger and fisherman's profit, but also to launch this Yiling War, Liu Bei is bound to win.
Liu Bei
Unfortunately, in the battle of Yiling in history, Liu Bei was defeated, and the main reason for Liu Bei's defeat was that he was too impatient, gave up the water army, and at the same time let the Shu army all be stationed in the dense forest, only to be found by Lu Xun to find the fighter, Liu Bei was defeated unwillingly and reluctantly, in fact, Liu Bei was not without the possibility of victory.
If Liu Bei did not abandon the water army, if Liu Bei did not let all the troops be stationed in the forest, if Liu Bei did not rush to a decisive battle, but took advantage of the contradiction between Sun Quan and Cao Pi, could not take Yiling and temporarily retreated, and waited until the autumn harvest and the weather turned cool before starting the war, if Liu Bei started from Wuling County in the south and sent another army to attack Lu Xun, then Liu Bei was still likely to win the Battle of Yiling.
Sun quan
If Liu Bei defeated Lu Xun in the Battle of Yiling, how would the situation in the world develop?
First of all, Sun Quan will never surrender, if he wants to surrender, the Battle of Chibi Sun Quan has already surrendered, Sun Quan's choice is only to resist to the end, with Sun Quan's characteristics, Lu Xun is only the first line of defense against Liu Bei, behind Lu Xun, there is obviously a second line of defense against Liu Bei in Jingzhou Jiangling City.
Sun Quan and Lu Xun
Jiangling City is the core of the whole Jingzhou, the city is solid, easy to defend and difficult to attack, when Zhou Yu led the army to attack Jiangling City defended by Cao Ren Town, it fought for a year, or Cao Ren took the initiative to abandon the city, Zhou Yu only occupied Jiangling City, it is a very difficult thing to siege the city, but if Liu Bei can not take Jiangling City, it is impossible to continue to attack Sun Quan, but the siege battle is a land battle, for Liu Bei, it is still certain.
And Jiangxia County is Sun Quan's third line of defense, this is the intersection of the dangerous Yangtze River and the Han River, is one of the best positions for Sun Quan to use the director of the water army to block Liu Bei, Liu Bei's water army strength is not as good as Sun Quan's water army strength, so Liu Bei can not capture Jiangxia County, is the reason for whether he can finally defeat Sun Quan, if the first two lines of defense Sun Quan are defeated, Jiangxia County may not be able to hold, because the military heart has been lost.
Battle of Yiling
Chai Sang (present-day Jiujiang) is Sun Quan's fourth line of defense, this is Sun Quan's last line of defense, if Chai Sang is lost, the whole of Jiangdong is no longer in danger, Sun Quan will begin to flee to the southeast coast, if not fled, Sun Quan will be captured by Liu Bei.
At the same time, Sun Quan will also continue to ask Cao Wei for help, just as Cao Wei rescued Sun Quan when he was attacked by Sun Quan in Xiangfan, Sun Quan was good at dancing and good at using political forces from all sides to seek balance, if Liu Bei grew, Cao Wei did not want to see it, so Sun Quan would desperately show favor to Cao Wei in exchange for support, even if he sent his son to Cao Wei as a hostage, Sun Quan would not hesitate.
Cao Pi
So there is a high probability that Sun Quan will do this, when Liu Bei attacks Sun Quan on the one hand, Sun Quan on the one hand to Cao Wei to send his son as a hostage, seek support, while actively resisting Liu Bei, as for surrender, Sun Quan's dictionary should not have this word, he is unlikely to surrender, but if the situation in the world develops in this way, it is an excellent opportunity for Cao Wei to unify the world, of course, the premise is that Cao Pi is smart enough.
The more vigorously Liu Bei and Sun Quan fought, the happier cao pi became, because Cao Wei was the yellow bird behind the mantis catching cicadas, and if Cao Pi could take advantage of the opportunity to attack before Liu Bei annexed Sun Quan, it would be a perfect opportunity for Cao Pi to unify the world, this opportunity was not even Cao Cao, only Cao Pi had it, but no matter how the situation developed, as long as Liu Bei won the Battle of Yiling, Sun Quan would be a loser.
Liu Bei, Sun Quan, Cao Cao
Sun Quan's best result is to flee in defeat, the worst result is to be defeated and killed, the biggest possibility is to be driven out of Jiangdong by Liu Bei, it is likely to come to today's Taiwan Island, spend a lonely life, and Liu Bei and Cao Pi crossed the river to rule.
