After the death of Tian Lei, Wang Jian and others, the star of Qin Dynasty died, Zhang Han was the last glory of Qin Jun, Hu Hai became dissolute after taking office, and Zhao Gao dominated the state affairs, which led to national corruption, boiling public grievances and smoke everywhere.
the Battle of Julu
At the beginning of the uprising, Zhang Han was the bane of the rebels. With the temporary captive army of Lishan Mountain, hundreds of thousands of people in Zhou Wen were defeated. After Zhang Han, Lien Chan and Lian Jie won. First he broke the Qi-Chu coalition, then he broke the Chu army and killed Xiang Liang in Dingtao. It can be said that before the Battle of Julu, Zhang Han frightened all the insurgents, and he took a team of torturers to wipe out the insurgents everywhere.
Some people say that after Zhang Han killed Xiang Liang, he didn't pursue victory and had no strategic vision to destroy Chu. However, after the destruction of the Chu army, the famous soldiers in Chu were all dead. At this time, Xiang Yu's reputation is not obvious. I didn't expect him to lose to this young man, so it is reasonable for him to lead the army to besiege Zhao. But underestimated Zhao's determination to resist.
the Battle of Julu
After Xiang Yu killed and seized the military power, the army was less than 60 thousand, and other governors stayed put and dared not solve Zhao's siege. With his fearlessness, Xiang Yu made his 50,000 troops win. As long as Xiang Yu fails once in the battle of Julu, the situation of the whole rebel army will be in jeopardy. Fortunately, Xiang Yu won the first world war. He led five Wan Chu armies and defeated Wang Li by a narrow margin. In fact, Xiang Yu didn't want the whole army to cross the river at first, but Chen Zhaoyu kept urging him, so Xiang Yu took the whole army, burned the tent, crossed the river with only three days' food, and fought a decisive battle with Qin Jun. After crossing the river, Xiang Yu took the Chu army straight into the tunnel and cut off Wang Li's food and grass, which greatly upset Wang Li's morale and boosted the morale of the Chu army. In the end, Xiang Yu captured Wang Li and 200,000 pieces of Qin Jun.
the Battle of Julu
After World War I, Zhang Han still had 200,000 troops in his hand, but he retreated to Wujia, holding on without letting Xiang Yu take any advantage. Zhang Han still had the idea of fighting Xiang Yu, but the fatuous Qin Ershi blamed him for Zhang Han's retreat and urged him to fight Xiang Yu. Zhao Gao also framed Zhang Han at this moment. Zhang Han sent people to Beijing to defend, but was assassinated by Zhao Gao. Zhang Han was very disappointed with Qin Ershi's stupidity and Zhao Gao's biting. He knew that even if he won Xiang Yu, Zhao Gao would not let himself go. If he loses, it is a dead end. In that case, it is better to surrender. So Zhang Han led two hundred thousand Qin Jun to surrender to Xiang Yu.
Therefore, the responsibility for Zhang Han's failure is not really his own. At that time, his surrender was actually a helpless choice.
