[Defeat again! 】

After the Battle of White Horse, Yuan Shao did not follow the advice of Fu Zhu to fight steadily, but personally led the army south, his army reached the south of the Yellow River, stationed south of Yanjin, and sent Wen Chou and Liu Bei to challenge Cao Cao again.

On the other hand, Cao Cao's army was also encamped under Nanhan, and he led a small number of troops to send people to climb the heights to observe Yuan Shao's military strength. After the watchers came down, they said to Cao Cao: "The enemy army has about five or six hundred cavalry. After a while, it was reported: "The cavalry is gradually increasing, and the infantry is innumerable." When Cao Cao found out, not only did he not worry, but let his cavalry unsaddle their horses, let them rest, and accumulate strength.

At this time, the baggage transported by Cao Cao's army from the white horse had already hit the road, and the generals under Cao Cao thought that the enemy had more cavalry, so it was better to go back to guard the camp. Xun You said: "This is to lure the enemy to the bait, how can you leave?" Cao Cao looked at Xun You and smiled slightly.

Yuan Shao's cavalry generals Wen Chou and Liu Bei led five or six thousand cavalry to arrive one after another, and began to attack Cao Cao's baggage troops, scattered to loot supplies. Seeing that the enemy's formation was chaotic, Cao Cao decisively ordered to send troops, at that time Cao Cao only had more than 600 cavalry, but finally broke Wen Chou, Liu Bei's troops, and Wen Chou was killed on the spot, and Yan Liang and Wen Chou were both famous generals in Yuan Shao's army, and the death of the two of them greatly hit the morale of Yuan Shao's army.

Cao Cao used Xun You's strategy to lure the enemy and successively eliminated two generals of the enemy army, and obtained a certain opportunity for Cao Cao's army before the decisive battle of Guandu.

[Guan Yu leaves]

In history, Guan Yu was Liu Bei's loyal subordinate, although he temporarily took refuge in Cao Cao, but in Cao Ying's heart in Han, Cao Cao admired Guan Yu very much at that time, and was more concerned about him, so he found that Guan Yu did not have the mind to stay for a long time, so he asked Zhang Liao to understand Guan Yu's thoughts, Guan Yu said to Zhang Liao: "I understand very well that Cao Gong treats me with deep affection, but I am favored by General Liu, and I have sworn to live and die with him, share weal and woe, and cannot break my oath." I won't stay here in the end, but I will not leave until I repay Cao Gong for meritorious service. ”

Zhang Liao showed Cao Cao Guan Yu's intentions, Cao Cao knew that Guan Yu would leave, not only did not blame him, but rewarded him heavily, wanting to keep Guan Yu, and then in the Battle of the White Horse, Guan Yu beheaded the enemy general Yan Liang in the army, and achieved a key victory for Cao Cao, so as to repay Cao Cao's kindness, Cao Cao also directly added Guan Yu as the Marquis of Hanshou Pavilion, in order to express his value for Guan Yu.

But all this couldn't stop Guan Yu's heart from returning, especially when he knew that Liu Bei was under Yuan Shao's command, he immediately sealed all the things that Cao Cao had rewarded, left a farewell letter to Cao Cao, and went to Yuan Shaojun to defect to Liu Bei. Cao Cao's left and right generals wanted to chase Guan Yu, and Cao Cao said: "He is his own master, don't chase him." This incident is also the prototype of Guan Yu's "Thousands of Miles Walking Alone" in "Romance of the Three Kingdoms".

【Yushu no Suke】

Under Yuan Shao's tremendous pressure, Cao Cao's territory can be said to be full of beacon fires, but this does not mean that Yuan Shao's rear is no problem. At that time, Wuhuan Sima Yan Rou sent Cao Cao during the Battle of Guandu to show his support for Cao Cao, so he was awarded the title of captain of Karasuma. And Xian Yufu defected to Cao Cao at Tian Yu's suggestion, led his subordinates to join the imperial court, and Cao Cao appointed him as the general of Jianzhong and supervised the military affairs of the six counties of Youzhou. Later, he went directly to the front line of Guandu to meet Cao Cao, and was worshiped by Cao Cao as the general of Zuodu Liao, named the Marquis of Ting, and then sent back to Benzhou by Cao Cao.

According to the record of "Wei Luo", Cao Cao said happily to Xian Yufu after winning the victory of Guandu: "Yuan Shao sent Gongsun Zhan's head before, and I felt that I might have been quickly eliminated by him, but now I have defeated him, which is both the will of heaven and your credit." ”

【Yuzhou Rebellion】

When Yuan Shao and Cao Cao Guandu confronted each other, Liu Bi, the leader of the Yellow Turban Army in Runan County, Yuzhou, betrayed Cao Cao and responded to Yuan Shao, Yuan Shao sent Liu Bei to aid Liu Pi, and the surrounding counties and counties rose up one after another to respond.

On the other hand, Yuan Shao sent an envoy to appoint Li Tong, the governor of Yang'an County, as the general of Zhengnan, hoping that he would serve him, and Liu Biao also secretly sent people to recruit Li Tong, but Li Tong was unmoved and rejected their proposals. At that time, someone persuaded Li Tong to contact Yuan Shao, and Li Tong pressed his hand on the hilt of his sword and reprimanded: "Cao Gong is wise and will definitely calm the world; Although Yuan Shao is strong, he will eventually be defeated at the hands of Cao Gong. I'm going to die. He immediately killed Yuan Shao's envoy and handed over the seal ribbon sent by Yuan Shao to Cao Cao. Later, Li Tong also attacked Qu Gong, the leader of the local forces in the county, and others, defeated them all, and pacified the Huai and Ru regions.

After Liu Bei and Liu Pi converged, he led his army to attack the Ru and Ying regions of Yuzhou, disturbing Cao Cao's rear, and since the south of Xudu, the officials and the people were uneasy, and Cao Cao was also very worried about this. Cao Ren proposed: "The south thinks that the general is currently holding Yuan Shao to a critical juncture, and he is unable to come to the rescue, and Liu Bei has led a strong army to suppress the border, so some people will inevitably betray. However, Liu Bei had just begun to lead Yuan Shao's soldiers, and he was not yet handy, so he attacked immediately, and he could defeat Liu Bei. ”

Cao Cao sent Cao Ren to lead the cavalry to attack Liu Bei, and Liu Bei had just led Yuan Shao's army, as Cao Ren expected, he was not satisfied, and finally lost to Cao Ren, the army was defeated and fled.

After Liu Bei returned to Yuan Shao's army, he secretly planned to leave Yuan Shao. So, he persuaded Yuan Shao to unite with Liu Biao in Jingzhou. Yuan Shao sent Liu Bei to lead his original troops to Runan, and united with the bandit Gong Du leader and others, with thousands of troops, Liu Bei once again began to disturb Cao Cao's rear. But after a defeat, Liu Bei's momentum this time was far less than the first time, so Cao Cao only sent his general Cai Yang to attack at first, but unfortunately Cai Yang was not a famous general, and he was completely defeated by the joint efforts of Liu Bei and Gong Du, and was defeated and died.

In this way, before Cao Cao completely defeated Yuan Shao, Liu Bei had been staying in the Yuzhou area to disturb Cao Cao's rear, forming a certain threat to Cao Cao, and then with the long-term confrontation between Guandu, Cao Cao faced a lot of pressure from Yuan Shao, and it was difficult to mobilize too many troops to crusade against Liu Bei, so he did not put too much energy on Liu Bei.

Later, Cao Cao completely defeated Yuan Shao at Guandu, and he personally led the army to drive Liu Bei out.

Before the decisive battle of Guandu, the situation had begun to show signs of development in Cao Cao's side, when Yuan Shao had successively lost Yan Liang and Wen Chou, two generals, and Liu Bei, who was sent to disturb Cao Cao's rear, was also defeated, and the core of Yuan Shao's group thought that Frustration had completely lost power, although Guan Yu also left Cao Cao, but this was really not a problem for the Cao Cao group, which was like a cloud, and Youzhou Yan Rou and Xian Yufu's Guishun also strengthened Cao Cao's strength while posing a threat to Yuan Shao's rear.

Before the horn of the decisive battle of Guandu was blown, the balance of victory had gradually tilted in favor of Cao Cao's side.
