In February 197, Liu Bei, Liu Biao, and Sun Ce fought in a three-way melee, which was difficult to solve. The emperor of the Han Dynasty summoned Cao Cao to commit crimes in the imperial capital, intending to rebel, and his crime should be punished. Ordered Taiwei Gao Yun to lead the troops to exterminate it to prove the law of the country.

Gao Yun raised 500,000 horses and horses of the Tiger Army, and divided his troops into five routes. made the tiger roar and ordered the overseer, and the Wei general Guan Yu led the troops out of Jinan and captured Taishan County; made the tiger roar to lead the overseers, and the general Zhang Liao led the troops out of Pengcheng and recaptured the county; made the tiger cut order to supervise the army, and the general Tai Shici led the troops out of Shouchun and captured Ancheng; made the tiger plunder order to oversee the army, and the general Zhang Fei led the troops out of Zaozhuang and captured Zou County; Gao Yun led the 200,000 Imperial Forest Army as the Chinese army, so that the hussar general Zhao Yun led the tiger roar and ordered the soldiers and horses to be the first, and the general of the expedition to the east Dian Wei led the tiger to order the soldiers and horses to be combined, and the troops went out of Xiapi and entered Yanzhou.

When Cao Cao attacked Xuzhou before, he was defeated by Zhuge Liang, Guan Yu, Dian Wei and Sun Ce's soldiers and horses, and returned in vain. In vain, a lot of soldiers, horses, money, and food were lost, and the morale of the three armed forces was frustrated.

With Cao Cao's wisdom, he naturally knew that a battle with Gao Yun would inevitably be fought sooner or later. Although Gao Yun deliberately released Gao Gan and Liu to him, Cao Cao also knew that this was just a temporary truce.

Therefore, in the past six months, Cao Cao has been constantly accumulating military strength and expanding troops and horses. To this day, the number of troops has also increased.

I heard that Gao Yun was coming from five directions, and it would be false to say that Cao Cao did not panic. Among the heroes of the world, none of them are willing to fight the Tiger Wei Army head-on.

But Cao Cao also knew that this battle was unavoidable. An urgent order was issued to recall all the heroes and fierce generals from all over the country, defend Yanyu, and fight with Gao Yun.

Yanzhou headquarters, Cao army camp, civil and military generals are lined up on both sides. Cao Cao said: "Now Gao Yunqi's army of hundreds of thousands of people has invaded, divided the army into five routes, and falsely claimed to be one million. Therefore, I urgently invite you to come and discuss the strategy of defending against the enemy. It has been discovered that Gao Yun made Guan Yu, Zhang Fei, Zhang Liao, and Tai Shici order the soldiers and horses to take Mount Tai, Zou County, Qian County, and Ancheng; Gao Yun led a large army, numbering about three or four hundred thousand, and marched westward. Zhao Yun has arrived in Xiaopei, and his intention must be in Yanzhou. How to resist it, I would like to hear your opinions."

As soon as Cao Cao said this, everyone in the civil and military was panicked and talked about each other. Xun Yu and Xun Yu discussed for a long time, got up and said to Cao Cao: "Lord, Gao Yun has broken Yuan Shao, his morale is strong, and he has a grand army this time. In the opinion of subordinates, it is advisable to avoid its edge for the time being. The lord can gather soldiers and horses and camp them in Shanyang so that they can support everywhere. Command the cities to hold out without a fight, until the time comes."

Cao Cao shook his head and sighed: "If it is for others, Wen Ruo's method is the safest. But you don't know, the Huwei Army has a siege weapon, known as the Thunderbolt Cannon. The stone cannon was launched, and the boulder flew and could reach two hundred paces away. No matter how strong the walls are, they can't stop it."

When the following civil and military generals heard Cao Cao's words, they were all stunned and felt incredulous.

Cao Cao said gloomily: "If I didn't see it with my own eyes, I wouldn't believe it." But this is the case, and there is no room for us not to fight. Although the Huwei army has many soldiers and horses, it is divided into five routes, and it is bound to disperse. This is where Gao Yun made a mistake, and he can break all the way first to frustrate his spirit. Guan Yu and Zhang Liao are both wise and brave generals, and it is not easy to break them; Dian Wei out of Shouchun to take Ancheng, hundreds of miles away, can be ignored first; The remaining road is Zhang Fei's tiger plunder order, I know Zhang Fei, he is brave and strategic, and he can be broken in a battle. If Zhang Fei can be broken first, not only can Zou County be protected, but also the shortcut to Gao Yun and Guan Yu's support can be blocked. After that, Guan Yu can be broken. What do you think? ”

When everyone heard Cao Cao's words, they all praised and nodded yes.

Cao Cao immediately issued an order, "Yuan let listen to the order"

Xiahoudun hurriedly took a step forward and arched his hand: "The last general!" ”

"I will be with you 100,000 elite soldiers, and then Cao Ren, Cao Hong, Xiahou Yuan and Xia Hou Wushuang will help you, go to Zou County quickly, and be sure to break Zhang Fei all the way first!"

"Order!" , Xiahoudun was full of confidence, stepped forward to receive the arrow, turned around and strode away.

Cao Cao passed another order: "Xu Huang listens to the order!" ”

"In!"

"With your 30,000 soldiers and horses, go to Xiaopei first, build fortifications, and stick to the city wall to block Zhao Yun. I led the army, and then came."

"Order!" Xu Huang took the order and left on his own.

After sending these two roads, Cao Cao personally commanded 200,000 soldiers and horses, gathered a group of ministers and brave generals, made Lu Bu the first, and Cao Xiu as the rear, and the troops went out of Yanzhou and went to Xiaopei to meet the main force of the Huwei army.

Zhang Fei was ordered to send troops to Zaozhuang to capture Zou County, which was only 200 miles away. If you follow Zhang Fei's character, he must be a fast horse, and he will arrive in one day.

But this time, Zhang Fei was very abnormal. The army was very well prepared for the grain and grass baggage, and after walking less than a hundred miles to the northwest, it stopped on the south bank of the Mengjiang River.

This Mengjiang River is 100 miles southeast of Zou County, Zhang Fei actually set up camp on the south bank, and lived for many days, without any intention of entering the army.

Xiahoudun sent troops from Yanzhou, trekked four or five hundred miles, and hurried to Zou County, but did not see Zhang Fei a single soldier. After sending scouts to investigate, it turned out that Zhang Fei had set up camp on the south bank of the Mengjiang River.

Xiahoudun was patient again and waited for five days. The news that came back from the investigation was that Zhang Fei still did not move.

At this time, Xiahou couldn't bear it anymore, and summoned Cao Ren and them to discuss: "The lord ordered me to come here in order to defeat Zhang Fei and first frustrate the spirit of the Huwei army. And now that Zhang Feitun is south of the Mengjiang River, he is not moving, what do you think? ”

Cao Ren replied: "Could it be that Zhang Fei got the news earlier, knowing that we were waiting to lead an army of 100,000 to come, and knowing that he was outnumbered, he stopped at Mengjiang and waited for the time to march?" ”

Xia Hou Wushuang shook his head thoughtfully and said, "I'm afraid not, with Zhang Fei's temperament, he will definitely not retreat because of the strength of the army." In the past, in front of the Tiger Prison Pass, the guy fought fiercely with Lu Bu, knowing that he was invincible, but he was never tired, and he still did not retreat after killing more than 100 people. It can be seen that Zhang Fei is by no means a timid person. I'm afraid that there is something else to do now."

Cao Hong was very angry, and said disdainfully: "Zhang Fei is brave and unscrupulous, he is a husband, why argue." Since he stationed troops on the Mengjiang River, we will kill them across the river and break them. Is it possible to fight with him from afar here, delaying the order of the main army? ”

Xiahou Yuan also echoed, "That's right, don't worry about it." The art of war cloud 'the double of the soldier will attack', which is at this time. Our army is 100,000, and Zhang Fei's soldiers and horses are only 50,000. The water of the Mengjiang River, but more than ten zhang, can be crossed by whipping. Homeopathic killing will pass, and the battle can be decided. broke Zhang Fei, and then took the road to Changxi, in order to attack Gao Yun's back road. Fight with the lord on both sides, and the big thing is decided! ”

Xiahou Yuan's words made everyone excited. If this can be done, it will indeed be a great feat. As long as Zhang Fei is broken, then he can go straight behind the main force of the Huwei Army. Although it is impossible to defeat the main force of the Huwei army, it is very likely to burn the grain and grass supplies in the rear of the Huwei army.
