Those who are familiar with the history of the Three Kingdoms know that the Battle of Yiling was the last of the "Three Great Battles", and Luo Guanzhong, the author of the Romance of the Three Kingdoms, made a very exaggerated description of the Battle of Yiling, saying that Liu Bei raised the strength of the whole country to cut down Wu, and the troops dispatched were about 700,000, which showed his determination to avenge Guan Yu. Unfortunately, Liu Bei's all-out attack was disintegrated by Lu Xun, and the situation of the Three Kingdoms also quietly changed, and his defeat directly contributed to the future unification. However, the real Battle of Yiling in history was not so large in scale, because the troops sent by Liu Bei were only 50,000 people in total.
Regarding Liu Bei's reasons for cutting down Wu, in fact, many people have walked into a misunderstanding, he is not only avenging Guan Yu, his deeper purpose is to take advantage of the opportunity to annex Eastern Wu. Liu Bei was not a dimwitted monarch, nor was he a hypocrite, his heart worrying about the people of the world was true, and the heart of the Xingfu Han Room was also true. Along the way, Liu Bei has experienced too much, he conforms to the people's hearts, wins the will of the people, and he can only take the road of "people" without taking advantage of the time and place. Fortunately, Liu Bei succeeded, although he attacked Liu Zhang, although it was a bit unkind, but in the chaotic world, the weak were doomed to be eliminated by the strong, which was an immutable law. However, Guan Yu's death greatly stimulated Liu Bei, and he decided to cut down Wu almost instantaneously.
It should be known that the ancient people's local concept was extremely strong, and Jingzhou was the foundation of Liu Bei, and the reason why he was able to establish the foundation of Shu Han was largely dependent on the Jingzhou shi clan. Then a passage in the "Romance of the Three Kingdoms and The Biography of Liu Ye" basically pointed out Liu Bei's thoughts: "Although Shu is narrow and weak, and Beizhi wants to strengthen himself with might, he is bound to use the crowd to show that he has more than enough." And Guan Yu and Bei, righteousness as kings, enyou father and son; Yu death can not serve the enemy for the Xingjun, and the distinction between the beginning and the end is insufficient. Guan Yu's position was very important, if Liu Bei turned a blind eye to his death, he would only damage his own foundation, and those who followed him in the beginning inevitably left one by one, in order to envelop this group of people, he had to take this step.
Moreover, Liu Bei was not a brave and resourceful man, he had carefully studied the form of the time before he sent his troops, because the Shu state occupied the natural danger, Cao Wei was helpless for a short time, and there was Zhuge Liang sitting in the rear, which was even more impeccable. On the other hand, Eastern Wu was attacked on both sides, on the one hand, Sun Quan not only had to bear the anger from Liu Bei, but also to prevent the Wei army from attacking, and once Wei Shu reached a consensus, Eastern Wu was very likely to be divided in two. Therefore, for Liu Bei's revenge, Zhuge Liang did not stop it, and Liu Bei rarely let him accompany him, and his move was enough to see some problems.
After Pang Tong's death, Zhuge Liang became Liu Bei's only backbone, and now that he was gone, he could only entrust the base camp to Zhuge Liang to take care of. In addition, from the day Zhuge Liang came out of the mountains, he had always advocated the formation of the Sun Liu Alliance, and Cao Cao's power was extremely large, and if he did not do so, he would not be able to lay the foundation for the situation of the three divisions of the world. However, Guan Yu's death was unexpected by Zhuge Liang, so his position was extremely embarrassing, because he was the main person in charge of the "Sun Liu Alliance", and his brother Zhuge Jin was also a high-ranking official in Eastern Wu, and he was deeply respected by Sun Quan, and it was inevitable that there would be some discord between him and Liu Bei.
Since he said this, he has to say some Zhuge Jin, he has been running for Sun Liu Alliance, Liu Bei looked at Zhuge Liang's face, and did not give him less steps. However, in the battle to attack Guan Yu, Zhuge Jin made a great effort, and later he was even given the title of Nan Commandery Taishou. Unexpectedly, when Liu Bei was rejuvenating his troops, he actually came to "calm things down" and once again posed as an old and good man, how could this make Liu Bei not angry? Therefore, although Zhuge Liang did not approve of Liu Bei's cutting of Wu, he did not dare to interject, and could only obediently do a good job in logistics, and Liu Bei, who was nearly a year old and had lost his spirit of adventure, did not dare to pour out of the nest, and could only take 50,000 soldiers and horses.
It is worth mentioning that these 50,000 soldiers and horses are also "patchwork from east to west", of which more than 30,000 are Shu troops and more than 10,000 are Wuxi Barbarians, which together can reach 50,000. In addition, Sun Quan also wrote a distress letter to Cao Pi, which indicated that Liu Bei only had 40,000 troops and horses. It can be seen from this that Although Liu Bei did not dare to make a desperate bet, Sun Quan did not dare to fight with one of them, and the mere 50,000 troops scared him to surrender to Cao Wei, and the helmsman of Eastern Wu was not as extraordinary as the legend.
