A case study of military strategy in the late qin dynasty. In July 209 BC, Guangwu and Chen Sheng revolted in the name of Fu Su and Xiang Yan, and put forward the slogan "No way to cut, no way to attack Qin". After the rebels captured Chen Jun, they decided to establish a political power to confront the State of Qin, so they claimed the title of king, taking Zhang Chu as the pseudo-king (deputy king). At this time, the storm of peasant uprising swept across the country, and the insurgents included Ying Bu, Qin Jia, Zhu Jishi, Zheng Bu, Ding, Xiang Yu and Liu Bang. In order to deal a heavier blow to the Qin Dynasty, Chen Sheng decided to take Xianyang as the main force, and divided his troops to slightly take counties. Guangwu ordered the generals to attack Xingyang in the west and prepare to enter the customs. Later, because Xingyang was not captured, he sent Zhou Wen as a general, bypassing Xingyang and Luoyang, and directly taking Xianyang; Liu Song was sent to attack Nanyang, headed for Wuguan, and bypassed Xianyang from the south; Think that the general, Shao sister-in-law is the guard, and the commander is around, and capture the former Zhao area; Send Deng Zong captured Jiujiang county; Send Zhou to the city to capture the original Wei area; Send Zhao Ping to fetch Guangling. In terms of attacking Xianyang in the west, Guangwu and others besieged Xingyang City, but they couldn't attack it for a long time, and the war situation was in a stalemate. Song Liujun once captured Nanyang, but Nanyang developed slowly, and finally failed to enter Wuguan. Zhou Wen led the army to capture the stage less than a hundred miles away from Xianyang, Qin Dou, which seriously threatened Qin's heart. Qin Ershi was frightened when he heard the news. He fought back against the rebels with hard-working "sinners" and troops defending the Huns. In terms of capturing counties and counties, Chen Wu led 3,000 people to capture more than 30 cities successively, entered Han in August, and stood on his own feet as king at the instigation of Zhang Er and Chen Yu. He was too busy expanding his territory to cooperate with the rebels against Qin. After Zhou captured the land of Wei, he established the old aristocrat Wei as Wang Wei and became independent from Chen Sheng. Deng Zong went to Jiujiang and Zhaoping went to Guangling. In 209 BC, Zhang Han, the general of the Qin Dynasty, led the "torturers" to resist Zhou Wenjun. In the Battle of Hong Men, Zhou Wenjun was defeated and withdrew from Guanzhong. Since then, he has been pursued by Zhang Hanjun and completely annihilated. Guangwu led an army to besiege Xingyang for more than four months. When Qin Jun approached Xingyang, there was internal division. Tian Cang and Li Guifei were ordered by Chen Sheng to kill Guangwu. Chen Sheng had to take Tian Cang as the general. Tian Cang died in Aocang, and the troops were defeated. Gui Li was attacked by Qin Jun, defeated and killed. After solving the siege of Xingyang, Zhang Han continued to advance to Chen County. Chen Sheng personally bid out of the city. County magistrate Chen can't keep it. Chen Sheng wanted to return to the original uprising area, so he went to Xiachengwen, where he was killed by the traitor Zhuang Jia. After Chen Sheng's death, the main force of the rebel army was defeated, leading to final failure.

Chen Sheng and Guangwu failed because of their mistakes in subjective guidance. First, leaders are complacent, divorced from the masses, have inhuman contributions, and undermine internal unity; Second, there is a lack of vigilance, experience and methods for the separatist activities of the old aristocracy; Third, it failed to unite the insurgents from all over the country to form an anti-Qin alliance; Fourth, there is a lack of calm analysis and correct decision-making in strategic guidance.
