Introduction: In 209 AD, Chen Sheng and Wu Guang led a peasant uprising against the rule of the tyrannical Qin. Qin II was surprised by Chen Sheng's peasant uprising, but there was no one available in the dprk, and all the famous generals were killed by himself. Qin II asked the courtiers if there was any way, and some people proposed that Zhang Handan be allowed to deal with the peasant revolt. Zhang Handan was a famous general in the last years of the Qin Dynasty, and Zhang Handan was ordered to quell the rebellion for his country when he was in danger. As the last famous general in the last year of the Qin Dynasty, if he failed, the Great Qin Empire would collapse.

When Chen Sheng's hundreds of thousands of troops attacked Hangu Pass, Zhang Handan used the prisoners of Lishan to form an army with extremely strong combat effectiveness. Zhang Handan defeated Zhou Wen's hundreds of thousands of troops with an army of prisoners, and Zhang Handan defeated the combined forces of Qi Chu, and Xiang Yu's uncle Xiang Liang was killed in this battle. After Zhang Handan defeated the rebellious army, Zhang Handan's battles were victorious one after another, and Zhang Handan made his own efforts for the rule of the Great Qin Empire. The Great Qin Empire was briefly stabilized by Zhang Handan's victory, and after the failure of the Chen Sheng Wuguang Uprising, Xiang Yu and Liu Bang continued to lead the peasant revolt against the Qin Dynasty.
Xiang Yu defeated Zhang Handan's army at the Battle of Julu, and after Zhang Handan was defeated, he also hoped that the imperial court would reuse him. At the end of the Qin Dynasty, the world was in chaos, and in the middle of the dynasty, Zhao Gao was monopolized, because of Zhang Handan's defeat Qin II was very angry, as a famous general who was brave and good at war, how could he fail miserably. Zhao Gao's heart was extremely vicious, and he naturally wanted to be held responsible for Zhang Handan's failure, so Zhao Gao sent someone to blame Zhang Handan's body. Zhang Handan's face changed drastically after he knew it, and Zhao Gao added the blame to himself, and he could not avoid death.
Zhang Handan sent Sima Xin to Xianyang to explain the situation, but unexpectedly Zhao Gao's eunuch was missing, and Zhao Gao knew that Zhang Handan would send someone to Xianyang to explain, but Zhao Gao did not care what happened to Zhang Handan. Anyway, Zhang Handan failed, zhang Handan could not avoid death, and zhao Gao still had the final say in the imperial court. Sima Xin stayed in Xianyang, and Sima Xin felt that the place where he was staying was very unsafe, and Sima Xin feared that Zhao Gao would send someone to kill him. Sima Xin fled back to the army in fear, and Zhao Gao finally sent someone to hunt down and kill Sima Xin, but Sima Xin had already escaped, and Zhao Gao did not kill Sima Xin.
After Sima Xin returned, he persuaded Zhang Handan to abandon Qin and surrender to Chu, and Sima Xin said to Zhang Handan: Zhao Gao is doing things in the dprk, the people below have done nothing at all, we will be jealous when we win the war, Zhao Gao will be jealous, and if we lose the war, Zhao Gao will find a crime to execute us, please consider it. Chen Yu also played a letter to Explain the current situation to Zhang Handan, and Zhang Handan felt that they were right after reading it, and Zhang Handan decided to defect to Xiang Yu. Why did Zhang Handan decide to defect to Xiang Yu instead of Liu Bang? In fact, Zhang Handan felt that Xiang Yu was a hero, Xiang Yu was the only one who had defeated him in the war, Xiang Yu and Zhang Handan were all generals with high martial arts, and Zhang Handan felt that it was not shameful for him to throw himself under Xiang Yu's door.
The situation in the last years of the Qin Dynasty left Zhang Handan helpless, and Zhao Gao had the power to deal with Zhang Handan, and Zhang Handan's victory and defeat in battle were all seen by Zhao Gao. Zhao Gaozhuan killed Zhongliang, and the central government was controlled by Zhao Gao, and if Zhang Handan did not defect to Xiang Yu, Zhao Gao would kill Zhang Handan. Liu Bang was a figure from a low-level background, and Zhang Handan was an official of the imperial court, and Zhang Handan could not have defected to Liu Bang to do things. Zhang Handan also looked down on Liu Bang's army, on the contrary, Xiang Yu's origin was a nobleman of the Chu State, and Zhang Handan valued his personal origin more.
Zhang Handan could not betray his own country as a man, but only the situation at the end of Qin forced Zhang Handan to decide to betray, and since Zhang Handan chose Xiang Yu, he could not defect to Liu Bang again, because Zhang Handan could not have a second betrayal, otherwise Zhang Handan would bear the insult, which was not allowed by Zhang Handan as a person. Zhang Handan was also a hero at the end of the Qin Dynasty, and Zhang Handan was crowned the King of Yong after he defected to Xiang Yu, and Zhang Handan's betrayal ushered in a fiefdom. But Zhang Handan's heart still fantasized about the Great Qin Empire, in 205 BC, Liu Bang led an army to attack the abandoned hill where Zhang Handan was located, Liu Bang has been unable to fight, and finally the Han army flooded the city with water, and after the city was breached by the Han army, Zhang Handan committed suicide.
Conclusion: Zhang Handan was a hero of the Great Qin Empire, but Zhang Handan was not in time, if Zhang Handan was born in the era of Qin Shi Huang. Presumably, Zhang Handan's ending would not be so tragic, Zhang Handan did not meet a Ming Jun, he was just fighting for the dark and brutal Great Qin Empire, Zhang Handan thought that the Great Qin Empire would give him good treatment, Zhang Handan did not expect that he was charged with a defeat, even so, Zhang Handan before committing suicide, he still had the Great Qin Empire in his heart.
