In the nineteenth year of Jian'an (214), in July, Cao Cao was afraid that Liu Bei would be big, so he wanted to take the lead in attacking Hanzhong, and without Hanzhong, there would be no Shu.

With Zhang Jaw as the vanguard, he personally raised an army of 100,000 to enter Chang'an, Ma Chao found out the news and quickly reported it to Liu Bei.

Liu Bei heard the news. Immediately ordered Zhang Fei, Wei Yanhui and Ma Chao to take Wudu and Yinping, and cut off the sloping valley where Cao Cao attacked.

He personally raised 50,000 troops, with Huang Quan and Zhao Yun as the vanguard to take Nanzheng, and the two led the army to Nanzheng, and Huang Quan sent envoys to persuade him to surrender.

After Zhang Lu received the letter of persuasion, he discussed with everyone, and his brother Zhang Wei resolutely refused to surrender and fought with the generals Yang Ang and Pang De.

Zhang Weitan heard that Huang Quan was no more than 10,000 people, and Liu Bei was nearly a day's journey away from Huang Quan, and he had a cavalry of 3,000 soldiers and horses in his hands, and the horses were purchased from Wudu and other places, and the combat power was very strong, and it only took a few hours to defeat Huang Quan, not to mention that Nanzheng had tens of thousands of soldiers and horses, all of which were dispatched.

Zhang Wei went out of the city to invite the battle, and Huang Quan discussed with Zhao Yun. It was decided that Huang Quan would line up in the south of the city, tired of Zhang Guards. Zhao Yun led a thousand cavalry to find a suitable place to hide the troops, look for flaws, and break the enemy with one blow!

Huang Quan arranged the 9,000 infantry into a circular phalanx, led by the large shield infantry, followed by the spear, then the strong crossbow, and then the pikemen. Finally, there are the sword and shield soldiers. Huang Quan left a thousand elite soldiers and horses to support the gap at any time.

Zhang Wei saw that Huang Quan was using turtle tactics, and immediately surrounded the army to attack, and the cavalry did not move, waiting for Huang Quan to appear a gap.

As soon as Huang Quan saw that Zhang Ren's cavalry did not move, he immediately scattered the formation and wanted to connect with his short soldiers, and the two armies were killed in one place, but Huang Quan's army still acted in a circle, but it was magnified, the spearmen did not move, the sword soldiers were killed in the formation, and the two armies fought together, and Huang Quan's command was far above Zhang Wei, so Huang Quan had a slight upper hand.

Seeing this, Zhang Wei commanded the cavalry to attack, and Huang Quan immediately called gold. The swords retreated, the bows and crossbows responded, and the spearmen retracted.

Zhang Ren's cavalry didn't know where to start, so several times, the cavalry was blocked by spears, and hundreds of losses were lost, but it was not easy to start, so several times, the morale of Zhang's guards and horses was greatly reduced.

Zhang Wei ordered Pang De to lead the troops to rush into the enemy formation, the two armies fought, Pang De was extremely brave, and entered the battle several times, but Huang Quan commanded the crossbowmen, shot the soldiers and horses behind him, and blocked the receiving soldiers and horses.

Zhang Wei used wheel warfare, quietly waiting for Huang Quanjun to get tired. The two sides pulled for three hours. The cavalry led by Zhang Wei was once again forced back by Huang Quan.

Zhao Yun seized the opportunity of Zhang Wei's cavalry retreating and the formation was scattered. took the opportunity to attack and approached the Zhang Wei cavalry.

Zhang Wei was shocked and commanded the redundant infantry to block. Zhao Yun was born in Baima and was well versed in the method of guerrilla. Use cavalry mobility to bypass the infantry and go straight to Zhang Wei.

Huang Quan saw that Zhang Wei's soldiers and horses were a little confused, and keenly judged that there might be a situation. Ordered an offensive posture and entangled Zhang's guards.

Zhao Yun killed in front of Zhang Wei. Zhang Wei was unexpectedly timid and turned his horse away. Zhao Yun took advantage of Zhang Wei's inability to command the soldiers and horses, and the cavalry impact formation was scattered, cutting Zhang Wei's cavalry into two sections.

Zhao Yun ignored others, captured the thief and captured the king, took Zhang Wei directly, Yang Ang came to the rescue, was shot in the shoulder by Zhao Yun, defeated in the city, Zhao Yun opened his bow and arrow, shot down Zhang Wei with an arrow, rushed forward, captured alive.

Zhao Yun defeated the cavalry, and attacked Zhang Wei's infantry, Huang Quan took advantage of the situation to attack, Pang Delai and Zhao Yun engaged, the two fought twenty rendezvous, Pang De saw that the soldiers and horses had been defeated, so he had to withdraw to the city.

Huang Quan won a great victory, and four or five thousand people fell, and the rest fled back to the city. Zhao Yun pressed Zhang Wei, Huang Quan treated him politely, set up a banquet to suppress the shock, and persuaded each other with good words: "I have always been very good with Zhang Lu, and today's Cao Cao's army is coming soon, Cao Cao's soldiers are sharp, and he is not an easy person to defeat, so I am here to discuss with you and others the plan to retreat from Cao, and I hope you will convey it." ”

After that, let it go back to the city. Zhang Lu saw that his younger brother was defeated and captured, and his heart was flustered, and soon Zhang Wei returned.

Zhang Lu asked, "How to come back?" ”

Zhang Wei told him the truth, Zhang Lu sighed, asked Ji and Yan Pu, Yan Pu said: "On the power, soldiers and horses, righteousness is the best to return to Cao Cao, Cao Cao has entered the valley at the moment, but wait for Cao Cao for more than a month, if the moon comes, you can return to Cao Cao." If he doesn't come, then Ezekiel Liu Bei will come and join him. ”

Zhang Lu followed his words and agreed with Huang Quan to surrender in a month. Huang Quan knew Zhang Lu's intentions and reported back to Liu Bei, and Liu Bei left Huang Quan to be stationed under the city of Nanzheng and came from Yangping Pass.

Zhang Fei and Wei Yan arrived directly at the next defense, at this time, Ma Chao has been here for nearly a year, for a year, Liu Bei sent Li Hui to keep in touch with Ma Chao and deliver grain and grass to him, and Ma Chao recruited Qiang Di in Wudu County, attacked Yongliang, listened to the news, and planned the geography.

Ago, Ma Chao learned that Han Sui's son-in-law Yan Xing had defected and led troops to attack Han Sui, but was defeated by Han Sui and had defected to Cao Cao.

Ma Chao sent someone to contact Han Sui, made a good relationship with him, and persuaded him to unite with Liu Bei to resist Cao Cao, Han Sui discussed with the general Cheng Gongying, and Cheng Gongying said: "The general has been in the middle of his life, and he is very kind to Qiang, if he goes to convene, he can gather tens of thousands of soldiers and horses, which is enough to be dominant, why bother to rely on Liu Bei and be under the people." ”

Han Sui followed his words, refused Ma Chao's envoy, and went to Qiang.

This time, Cao Cao's march was reported to Liu Bei after Ma Chao learned about it, and Liu Bei raised his troops. One step ahead, Ma Chaohui, Zhang Fei and Wei Yanhou, immediately took down the two counties of Wudu and Yinping, and the two counties responded to each other, and Lei Ding led thousands of men and horses to help in the battle.

The three of them went around to the sloping valley and came to the front of Yangping Pass. Cao Cao's troops entered the valley, and when he heard that Liu Bei raised troops to attack Hanzhong, Liu Ye persuaded: "Prime Minister, the terrain of the valley is steep, extremely difficult to walk, and there is a natural danger in Yangping, and it is extremely convenient for Liu Bei to enter Hanzhong.

If it goes on like this, even if it reaches Hanzhong, I am afraid that it has already fallen into the hands of Liu Bei, so it is better to retreat to Chang'an, send troops to seal the dangerous points, train soldiers, and cultivate farmers and support the people.

In this way, if Liu Bei comes, he will wait for work at ease, and constantly consume his soldiers and people's strength, and then Liu Bei will only have to sit and wait for destruction. ”

Cao Cao listened and said: "Instead of waiting, it is better to go down with a drum, take advantage of Liu Bei and Zhang Lu to fight, break through Yangping, and enter Hanzhong." ”

So he didn't accept Liu Ye's words, Sima Yi said: "If the prime minister wants to enter the army, he should guard against Ma Chao, the military capital." ”

Cao Cao said: "I have sent Cao Hong and Cao Xiu to break it." After that, he ordered Zhang Jaw and Zhu Ling to march. He also ordered Xiahou Yuan to go to Han Sui to prevent him from uniting with Ma Chao.

Zhang Jaw and Zhu Ling arrived at Yangping Pass, only to see dozens of strong barracks standing in danger, and Zhang Jaw set up a camp to fight the enemy and scold the array, but the camp did not move.

Zhang Jaw couldn't help but be suspicious, led his troops to attack, and found that the camp only had a few thousand defenders, and they were all dispersed.

Holding hundreds of people, he asked, "Where are the guards?" ”

The people replied, "The general spares his life!" Liu Bei besieged Nanzheng, and the army had already returned to help, so there were no soldiers. ”

Zhang Jaw was overjoyed, and took advantage of the situation to attack Yangping, but the defenders did not surrender, Zhang Jaw saw that Yang Ping could not be settled, so he ordered a night of rest and broke the pass tomorrow.

That night, on the third watch, Zhang Jaw's personal soldiers hurriedly reported to Zhang Jaw and said: "The general is not good, the thieves attacked the camp." ”

Zhang Jaw said: "Yangping is only a few thousand soldiers and horses, how dare you attack the camp." ”

Just as he was talking, someone came to report: "The thieves who were captured during the day suddenly attacked, and they joined forces with the attacking battalion soldiers and horses, and the camp could no longer hold it." ”

Zhang Jaw hurriedly came out of the big tent, facing the fire, and there was a mess around, Zhang Jaw had just got on the horse, only to hear a loud shout: "Where to go Zhang Jaw Xiaoer, Zhang Fei is also here." ”

Zhang Jaw was shocked, did not dare to engage in battle, broke through and left, and made peace with Zhu Ling's defeated army after dawn. Go to Cao Cao and ask for guilt.
