In the Battle of Gaixia, Han Xin wiped out all the military leaders of Wei, Zhao, South Korea, Daiguo and Qi, and the rest of Ying Bu and Peng Yue took refuge in Liu Bang. In this context, the army attacking Xiang Yu is no longer the original vassal Coalition, but the Han army under the direct or indirect command of Liu Bang, which is equivalent to attacking Xiang Yu with the power of six countries. Although there were 65,438+people in the Battle of Gaixia, Xiang Yu was an exhausted teacher. And Liu Banglai supports people from all walks of life, such as Han Xin and Peng Yue, who basically save their strength. After they got the promise of Liu Bang's fief, they were even more eager to try. Under this balance, Xiang Yu's failure is inevitable.
From the battle of Pengcheng to the siege of Gaixia, the whole political and military situation of Chu and Han has undergone fundamental changes. In the battle of Pengcheng, the Chu army was in full swing, and there were many soldiers. Fan Zeng, Lu Bu, Long Qie and others were brave and good at fighting. Who is the butcher of the world at this time? It was none other than Xiang Yu, who was deeply rooted in the hearts of the people. Even Liu Bang's soldiers think so, including Liu Bang. Therefore, Liu Bang's attack on Pengcheng was based on a mirage, without any foundation. 560,000 troops are just a rabble pieced together by the 18-route swinging overseers. So, when Xiang Yu came back with 30 thousand fighters, both the geographical location and the people's hearts were immediately restored. What is the down-to-earth strength? This is it! The mob naturally dispersed in a hubbub. Liu Bang was no match for Xiang Yu's slaughter in the world at this time, and naturally lost.
It has been five years since Xiang Yu enfeoffed the world in the Battle of Gaixia. These five years, the change is really too great. First of all, the feudal lords of the 18th Route who were enfeoffed, except a few with little influence, were basically swept away by Han Xin on the eve of the Hai Xia War. In other words, Xiang Yu's enfeoffment system was gone after the Qin Dynasty, so Xiang Yu actually lost the strength to dominate the world, leaving a hollow reputation as a hegemon; Plus Xiang Yu is too conceited and willful to share profits with others. Han Xin, Chen Ping, Qing Bu and others used to be Xiang Yu's men, but later they left him one by one to go to Liu Bang. It was these people who killed him in the late Chu-Han War. In the past five years, he has used fewer and fewer civilian military commanders, and he has played less and less. Ying Bu rebelled, Fan Zeng died, Long Qie was drowned, and Xiang Yu became a real loner, a person who didn't even want to share profits with those who worked for him, let alone be kind to ordinary people, which would inevitably lead to a great loss of popular support.
In the five years of Chu-Han hegemony, although the Han army has repeatedly lost and fought, it will soon recover its vitality and then compete for it. That's because Liu Bang's political work is well done, which has been recognized and supported by the people, and his men have been supplemented. Han Xin and Peng Yue were both used by Hanwang, and now everyone's heart has changed! On the other hand, Xiang Yu at this time, the army was exhausted, and the generals who could lead the troops were almost lost, and the people's hearts were absent. As analyzed, "Korea has a world that is too (big) and half, and governors are attached to it. Chu Bing stopped (exhausted) to eat, and this day will also be the time of Chu's death. It is suggested that "it is better to take it because of its opportunity." "At this time, don't attack Chu Jun when he is tired. When he's done, there's no chance! Therefore, Liu Bang would rather tear up the peace agreement than fight this battle. Finally, he defeated the Chu army in the battle of Gaixia, and Xiang Yu defeated himself!
