After the Battle of Weinan, Cao Cao took full control of Guanzhong and completely opened the passage to Hanzhong, and in the twentieth year of Jian'an (215), Cao Cao personally led a large army to defeat Zhang Lu and successfully occupied Hanzhong.

【Aisle extinguishing】

In March of the twentieth year of Jian'an (215), Cao Cao, the Duke of Wei, personally led his troops to attack Zhang Lu, preparing to enter the place where the Di people lived from Wudu. The Di people intercepted on the way, and Cao Cao sent Zhang Zhanghe and Zhu Ling to defeat the Di people. In the summer, in April, Cao Cao left Chencang and arrived at Hechi. Dou Mao, the king of Di, had more than 10,000 people, and refused to surrender because of the dangerous terrain. In May, Cao's army defeated the Di people and carried out a massacre. In the same year, the generals of Xiping and Jincheng, such as Lu Yan and Jiang Shi, jointly killed Han Sui and dedicated his head to Cao Cao.

【Capture of Hanzhong】

In the autumn and July of the same year, Cao Cao, Duke of Wei, arrived in Yangping. Zhang Lu asked his younger brother Zhang Wei and his subordinate Yang Ang to occupy Yangping Pass and build a city wall more than ten miles long along the mountainside, which was difficult for Cao's army to overcome, so he withdrew his army and left. When Zhang Lubing saw that Cao Gong led his troops to retreat, he lifted the guard here.

Cao Gong secretly sent Xie Kou, Gao Zuo and others to risk a sneak attack at night, defeated the enemy army, killed Yang Ren, and attacked Zhang Wei, Zhang Wei and others fled overnight. Zhang Lu was defeated and fled to Bazhong. At that time, Liu Ye was the master and accompanied the army to the west. When Cao Cao arrived in Hanzhong County, the mountains were steep, difficult to climb, and the military rations were very scarce, so he said: "This is a place of delusion, whether there is or not, it doesn't matter." Our army is short of food, so it is better to return to the army quickly. Cao Cao personally led the soldiers back and ordered Liu Ye to supervise all the men and horses behind him and let them go out of the mountain in order. And Liu Ye calculated that Zhang Lu could conquer it, and the channel for transporting grain could not be continued, although he withdrew, the military horse still could not be intact, so Pegasus told Cao Cao: "It's better to devote yourself to attacking." Cao Cao then marched into the army and broke the enemy's army.

Cao Gong's army entered Nanzheng County, and all the treasures in the treasury of Zhang Lu's mansion were captured. Ba County and Hanzhong County all surrendered. revert the name of Hanning County to Hanzhong County; Anyang and Xicheng, which were carved out of Hanzhong County, were newly established as Xicheng County and set up Taishou; It was divided into Xi County and Shangyong County, and set up Du Wei.

There are other records about the capture of Hanzhong, Dong Zhao's record in the table above is that Cao Cao's soldiers inadvertently entered Zhang Wei's camp after retreating, and the enemy army was defeated.

Wei Mingchen played Dong Zhaobiao and said: "Emperor Wu Chengliangzhou engaged in the resignation of Wudu, saying that Zhang Lu is easy to attack, and the north and south mountains under Yangping City are far away, and they cannot be defended, so I believe it." And when he was about to perform, he was not as good as he had heard, but sighed: 'The business of others is less than people want.' 'Attacking the Zhutun on Yangping Mountain, both pulled out from time to time, and there were many soldiers and soldiers who were injured. Emperor Wu was frustrated, so he wanted to pull out the army and return to the mountain, and sent the late general Xiahoudun and the general Xu Chu to return the troops on the mountain. Before the meeting, the army did not return, and the night was confused, and he strayed into the thief's camp, and the thief retreated. After serving Xin Bi, Liu Ye and others, they said to Yu and Chu, saying, "The officers and soldiers have been given the thief to the tun, and the thief has dispersed." I still don't believe it. I saw that I was returning to Emperor Baiwu, and I was determined to enter the army, but fortunately I was captured. The officials knew about this recent matter. ”

Yang Ji said: "Emperor Wu began to conquer Zhang Lu, with 100,000 people, personally came to perform, instructed the strategy, because the people thought it was military food. Zhang Weizhi's guard, cover is not enough. The land is dangerous and easy to defend, although there are elite soldiers and tiger generals, it is impossible to do it. After three days of fighting against the army, he wanted to draw the army back, saying, 'Thirty years in the army, once holding with people, how'. This plan has been decided, Tianzuo Dawei, Lu Shou is self-destructive, so it is determined. ”

The world said: Lu sent the five senses to surrender, and the younger brother Wei Hengshan built Yangping City to refuse, and the king was not allowed to enter. Lu went to Bazhong. When the army runs out of food, Taizu will return it. Guo Chen of Xicao Pengdong County said: "No. Lu has surrendered, the envoy has not been opposed, although the guard is different, it can be attacked. The county army went deeper, and it was inevitable to retreat in order to advance. Taizu was suspicious. At night, there were thousands of wild mooses breaking through the guard camp, and the army was shocked. At night, Gao Zuo and others mistakenly met with Wei Zhong, and Zuo and others beat the drum and horn congregation. Wei was afraid, thinking that the army was hidden, so he surrendered.

【Zhang Lu came to descend】

Originally, Zhang Lu wanted to surrender to Cao Cao when Cao Cao's army came. But Zhang Ludi Zhang Wei did not listen, and led tens of thousands of horses to stick to Yangping Pass, which was broken by Cao Cao. When Zhang Lu heard the news, he wanted to kowtow and surrender. Yan Pu also offered a plan and said: "Now that you are forced to meet, you will definitely not be reused by Cao Gong, it is better to go to Puhu to resist first, and then offer him a gift and be a minister, so that you will be reused by Cao Gong." Zhang Lu then led his army to Bazhong. Before leaving, the people around wanted to burn all the treasures in the warehouse, Zhang Lu said: "I have the intention to return to the imperial court, but this intention has not been known to the Duke of Cao." We left today just to avoid the edge, and we had no other intentions. Treasure warehouses should be owned by the state. So he hid all the treasures before leaving.

After Cao Cao arrived in Nanzheng, he deeply praised Zhang Lu's behavior, and because Zhang Lu had already intended to be obedient, he sent people to condole. Zhang Lu took the whole family to meet Cao Cao, and Taizu appointed him as the general of Zhennan, treated him with courtesy, and named Zhang Lu as the Marquis of Langzhong (a "Marquis of Xiangping"), with 10,000 households. Cao Cao took him and his family back to Yecheng. Feng Zhanglu's five sons and Yan Pu and others were the liehous. For his son Cao Yu to marry Zhang Lu's daughter as his wife.

After Cheng Yin, Hou Xuan, Liu Xiongming and others were defeated by Cao Cao's army in Guanzhong, they all took refuge in Zhang Lu, and then they surrendered to Cao Cao together with Zhang Lu, and the official was reinstated, and the original Ma Chao's subordinate Pang De also surrendered to Cao Cao at this time.

It is said that Liu Xiongming refused to fight against Cao Cao with Ma Chao, and was sent by Cao Cao to collect the old department, but he was forced to rebel by his subordinates, and fled to Hanzhong after defeat, after he surrendered with Zhang Lu, Cao Cao saw him, and pulled Liu Xiongming's beard and said: "You old thief, where do I see you running?" Although Cao Cao was very angry at the time, Cao Cao did not pursue it, but restored Liu Xiongming's official position and transferred him to Bohai County, where Liu Xiongming later died.

[Rather be a slave for Cao Gong, not a guest for Liu Bei]

After Cao Cao broke Zhang Lu, Zhang Lu fled into Bazhong, and Huang Quan said to Liu Bei: "If you lose Hanzhong, the land of Sanba will be threatened, which will cut off the thighs and arms of Shudi." So Liu Bei took Huang Quan as his protector and led the generals into Bazhong. But Zhang Lu had already returned to Nanzheng and surrendered to Cao Cao.

According to the record of Huayang Guozhi, Volume 2, in the twentieth year of Jian'an (215), Cao Cao went west to conquer Zhang Lu, and when Zhang Lu fled to Bazhong, Liu Bei sent people to prepare to meet him, and Yan Pu persuaded Zhang Lu to surrender to Cao Cao in the north: "To assist in achieving great things, Cao Cao should be attached; If not, Ezekiel Liu Bei will come and join him. Zhang Lu said angrily: "I'd rather be a subordinate of Cao Gong than a guest of Liu Bei!" So he surrendered to Cao Cao.

The reason why Zhang Lu hated Liu Bei so much in history was not without reason. Liu Bei's excuse for entering Yizhou was to help Liu Zhang deal with Zhang Lu, and later Liu Bei poached his favorite Ma Chao from Zhang Lu, so it can be said that the relationship between the two is not good.

If Zhang Lu was forced into a desperate situation by Cao Cao~ he might have given up his previous grievances and turned to Liu Bei, but in fact, Zhang Lu had long intended to return to Cao Cao, and his advisor Yan Pu also supported Zhang Lu's return to Cao, and Cao Cao himself was willing to accept Zhang Lu's surrender after the war, and it was normal for Zhang Lu to dare to throw Liu Bei's face in this case.
