At the end of the Qin dynasty, people everywhere were dissatisfied with the tyranny of the Qin dynasty and began to resist the tyrannical Qin dynasty. Guangwu and Chen Sheng took the lead in the uprising, which was called Daze Township Uprising in history. Chen Sheng and Guangwu are both Chu people, but the biggest force in Chu is the Chu army led by Uncle Xiang Yan. Descendants of the previous six countries also stepped forward. Restored their country names. After Chu died in Xiang Liang, Xiang Yu became the supreme general. At that time, Zhao was besieged by the general's 400 thousand army, and the king of Zhao sent people to Chu for help.
So the king of Chu ordered Xiang Yu and Fan Zeng to lead tens of thousands of troops to rescue the siege of Julu, and Liu Bang set out from Chu to attack Guanzhong. The king of Chu promised that whoever attacked Xiaguan first would be the king of Guanzhong. Xiang Yu took the lead and led a great army north. In the first battle of Julu, Xiang Yu took out the momentum of burning ships and ordered the army to sink all his cauldrons and ships. After crossing the Zhanghe River, the only way to fight is to die. Chu Jun took out the determination to die, and confronted him for the first time, breaking up Qin Jun, who had besieged the stag, and lifting the siege of the stag.
At this time, when the princes of other roads saw that Xiang Yu's troops had won, they all rushed over without moving. Xiang Yu is their commander in chief, and Xiang Yu is about to have a decisive battle with Qin Jun. At this time, Qin Ershi heard the news and sent someone to question Zhang Han's responsibility. Zhang Han was afraid and sent Sima Xin, a long history, to Xianyang for instructions, but Zhao Gao refused to meet each other. After coming back, Zhang Han was scared, too. At this point, the surrender letter he sent also listed the fate of Tian Lei, Meng Tian and other generals of Qin, hoping that Zhang Han would surrender. Zhang Han wanted to conclude a contract, but Xiang Yu refused, and Xiang Yu defeated Qin Jun one after another. This led to Zhang Han's final surrender.
In the Battle of Julu, Qin lost all its main forces and accelerated its demise.
