Battle of Han River

The Battle of Han River was fought between the warlords Liu Bei and Cao Cao in 219 during the prelude to the Three Kingdoms period of Chinese history. The battle was the last major engagement in the Hanzhong Campaign, in which Liu Bei emerged victorious and subsequently declared himself King of Hanzhong.

Background
Cao Cao was defeated by Liu Bei at the Battle of Mount Dingjun in 219 and his general Xiahou Yuan was killed in action. In retaliation, Cao Cao led a large army to attack Liu Bei's camp at the south of the Han River. Liu Bei sent his generals Zhao Yun and Huang Zhong to defend. Huang Zhong and Zhang Zhu went to destroy the enemy's supplies while Zhao Yun would remain in the camp with Zhang Yi unless they did not return.

The battle
Huang Zhong's army moved to burn the supplies of grain Cao Cao had at the North Mountain; his troops marched in the night, and at sunrise they reached the granary. Wei general Zhang He's army arrived before Huang Zhong could successfully burn the grain. Cao Cao then sent Wei general Xu Huang to intercept Huang Zhong and block his retreat. He succeeded, and Huang Zhong's army was surrounded. Zhao Yun's army dispatched to look for Huang Zhong after he had not returned by noon.

Zhao Yun left Zhang Yi in charge of the camp's defense. He then departed to find Huang Zhong in battle, and successfully rescued him and retreated back to the main camp.

When Zhang Yi heard that Cao Cao's army was in pursuit of Zhao Yun, and was headed towards the main camp he thought they should close the gates and while they make preparation. However, as soon as Zhao Yun returned to camp he ordered all flags and banners removed, all drums silenced, and the gates to be left open completely. He stationed all his archers and crossbowmen in a covered area outside, and he stood in front of the gates. Fearing an ambush, Cao Cao ordered his men to retreat. As his men began to retreat Zhao Yun ordered his men to beat the drums as loudly as they could, and rain arrows down on the retreating enemy.

Zhao Yun, Huang Zhong, and Zhang Zhu closed down on Cao Cao's army. They rushed toward the Han River, and in confusion many were pushed in to the river and drowned. Meanwhile Meng Da and Liu Feng arrived and burned all the enemy supplies at the North Mountain.

Aftermath
Liu Bei came and inspected the battlefield and exclaimed, "Zhao Yun has valor through and through". He ordered a celebration to late that night honoring Zhao Yun. From then on, Liu Bei's army called Zhao Yun "General of Tiger's Might" (虎威將軍).
