What are some famous battles in ancient times where a small number of people defeated a large number?

"Sun Tzu's Art of War" says: "Soldiers are crafty." There were too many battles in ancient China in which a small number defeated a large number. I will give you two of the most familiar battles first.

1. In the Battle of Chibi, the ratio of the armies of both sides was 0.18:0.89. Cao's army numbered 230,000, and Sun and Liu's alliance numbered 50,000. This was originally a victory for Cao's army without any suspense, but in the end Cao's army was defeated and returned.

Because Cao Cao ordered all the ships to be connected together at that time, which made the momentum more powerful and looked quite bluffing. Unexpectedly, Brother Huang Gai in the Sun-Liu Alliance caught this point, During the battle, Zhou Yu asked Huang Gai to lead a small force to pretend to surrender. In fact, after approaching Cao's fleet, he began to set fire to the ships. Many of Cao's troops either drowned or were burned to death, and returned in defeat.

2. In the Battle of Julu, the ratio of the armies of both sides was 0.14:0.86. Xiang Yu had 50,000 soldiers and Qin had 300,000 soldiers. The Battle of Julu was not as simple as the Battle of Chibi. In summary, Xiang Yu had Strategy, on the other hand, the Qin army was not at the right time and the right place, and the people were not harmonious.

The Qin army was divided into two groups, led by Wang Li and Zhang Han respectively. The 100,000 troops led by Wang Li encountered a long period of continuous silver rain on their way here, and their equipment was soaked by the rain. Broken, the overall combat effectiveness dropped significantly. Wang Li led his troops to Guanzhong and was defeated by Cao Shen. Zhang Han led his troops to capture Zhao Di in one go. Wang Li also captured Xindu. Then when heading to Julu, Wang Li's 100,000 troops encountered Xiang Yu's five troops. Ten thousand soldiers and the dormant 350,000 giant deer Zhao army.

At this time, Wang Li and Zhang Han began to have conflicts and dislike each other. Without Wang Li's knowledge, Zhang Han had already sent people to find Xiang Yu to reconcile. Wang Li usually fought and charged, so for The formation was not well understood, but it quickly fell apart under the organized attack of Xiang Yu's 50,000 soldiers, and the entire army was wiped out in a month. At this time, Zhang Han led 200,000 troops to surrender to Xiang Yu. Later, all the soldiers were trapped and killed by Xiang Yu in Xin'an. So far, the Qin army had no chance to stand up. Xiang Yu won a complete victory in the Battle of Julu.
