In the Battle of Gaixia, Han Xin besieged Xiang Yu on all sides. Why did he leave a hole for mercy?

The reason why Han Xin laid siege to Xiang Yu with flying daggers and left a wide hole for Xiang Yu was not that Han Xin wanted to release Xiang Yu, but that was actually one of Han Xin's tactics. Han Xin, who is familiar with the art of war, also knows that Sun Tzu once said that if you go to besiege the enemy, if you don't leave a place for the other party to escape, it may make the enemy very resistant to his attack.

So at that time, although Han Xin led an army of 300,000, he still had to be careful of Xiang Yu's desperate battle. Moreover, the hundreds of thousands of troops brought by Xiang Yu this time are the most elite troops in the hands of Xiang Yu. It can be said that this is also the main force in Xiang Yu's hands, so Liu Bang and Han Xin are very careful about this.

In addition, among the people who followed Xiang Yu at that time, although people like Fan Zeng had left Xiang Yu, there were still many talents who followed Xiang Yu, so Han Xin should be careful of the schemes of those people. Han Xin also divided his 300,000-strong army into three parts in the war, and personally led one as the main force fighting Xiang Yu. It can be said that Han Xin's lineup this time is actually huge, and it is also both offensive and defensive.

Han Xin first lured Xiang Yu to charge and break through there with a small amount of troops, but the encirclement was round after round, which finally made the Chu army exhausted and finally made Han Xin divide-and-conquer. Xiang Yu also broke through in such a chaotic army. In the last ten, there were only 800 people left in the Wan Chu Army.
