The Battle of Hanshui was a battle in the Hanzhong region during the Three Kingdoms period at the end of the Han Dynasty, and the two sides of the battle were Liu Beijun and Cao Cao's army. In fact, this battle is only a local battle of the entire Battle of Hanzhong.
At that time, Cao Cao and Liu Bei were fighting for Hanzhong, and Cao Cao prepared a large amount of grain and grass, and Jitun was in beishan, preparing to fight a war of attrition with Liu Bei.
At that time, Huang Zhong suggested that Zhao Yun go to grab the grain, and the two discussed a time for Huang Zhong to go out on the expedition. As a result, Huang Zhong arrived at the agreed time but did not return, and Zhao Yun was worried that Huang Zhong would have an accident, so he only led dozens of cavalry out to look for Huang Zhong. The result happened to be a large force sent by Cao Cao.
Perhaps Cao Cao's army did not expect to be able to meet Zhao Yun, and as a result, he was stunned by Zhao Yun to break out, and he was also put together by Zhao Yun, and the loss was not small.

Unwilling to accept defeat, Cao Cao sent troops to fetch Hanshui from the Xiegu Trail and ordered Xu Huang to be the vanguard, Wang Ping was a general at Yamen at the time and knew the geography of Hanzhong well, so he was appointed by Cao Cao as a deputy pioneer to assist Xu Huang. However, the two still had differences.
Xu Huang is a fierce general with good strength. He wanted to order the army to cross the Han River and fight a battle. The fierce general is different, if you don't shoot, you will be already there, and if you shoot it, it will be a blockbuster. But Wang Ping was different, he thought that this was not a good thing, what if he had to encounter an emergency to retire?
Xu Huang did not listen to Wang Ping's persuasion and forcibly entered the army, as a result, he was defeated and escaped from death. After returning home, Xu Huang blamed Wang Ping and said, You see that our army is in danger, why don't you come to the rescue? In fact, Wang Ping was also quite wronged, he wanted to save them, and it was estimated that they were boiled by someone with a spoonful.
Besides, Wang Ping had also persuaded him, but Xu Huang didn't listen. Now a rake is thrown upside down. Looking at Xu Huang's angry look, like he wanted to kill people, Wang Ping was scared, prepared for a hot brain, simply reversed, and took advantage of the night to put a fire and run.
To say that Xu Huang was depressed enough, he had just lost the battle, his morale was low, he did not expect to be almost burned to death, and the deputy general also surrendered to the enemy, which made this fierce general attack his heart in a hurry, and he was frightened and broke his guts, and there was no way to go back to account for it.
He couldn't go back, so he had to abandon the camp and leave.
