Guan Yu quickly approached Yan Liang's army, rushed into the midst of the ten thousand troops, killed Yan Liang and beheaded him, and Yuan's army was defeated. After Cao Cao relieved the siege of Baima, the people who migrated to Baima retreated westward along www.biquge.info the Yellow River.

Yuan Shao led the army across the river to pursue, the army to the south of Yanjin, sent the generals Wen Chou and Liu Bei to continue to lead the army to pursue the Cao army, Cao Cao only had 600 cavalry at that time, stationed under the South Han, and the Yuan army had as many as five or six thousand cavalry, and there were infantry to follow behind.

Cao Cao ordered his soldiers to unsaddle their horses and deliberately abandon their baggage on the side of the road. Cao Cao suddenly attacked, and finally defeated Yuan Jun and killed Wen Chou, who was killed by the rebellious army, not Guan Yu who was killed and successfully retreated to Guandu. Yan Liang and Wen Chou were both famous generals in Hebei, but they were beheaded in a battle, and the spirit of Yuan Shao's army was bruised.

Yuan Shao built a turret, piled up soil like a mountain, and shot Cao Ying with arrows. Cao Jun made a kind of thunderbolt with a stone-throwing device, and the stone destroyed the building built by Yuan Jun. The Yuan army dug tunnels to attack again, and the Cao army also dug long trenches in the camp to resist, crushing the Yuan army's strategy. The two sides held each other for three months, Cao Cao's external situation was difficult, the front soldiers were short of food, the soldiers were tired, and the rear was not stable, Cao Cao almost lost the confidence to hold on, and one day he saw that the soldiers transporting grain were tired of running for their lives, and he couldn't bear it, and couldn't help but blurt out: "I want to defeat Yuan Shao for you on the 15th, don't let you work so hard again." ”

Cao Cao wrote to Xun Yu to discuss retreating to Xudu, and Xun Yu replied: "Yuan Shao gathered the main force in Guandu, and wanted to fight the lord. If you can't restrain Yuan Shao, you will be subjugated by Yuan Shao, which is the key to determining the general trend of the world. ”

"Back then, Chu and Han were between Xingyang and Chenggao, and no one in Liu Bang and Xiang Yu was willing to take a step back, and those who retreated first must be at a disadvantage. Now it has been half a year since the lord blocked ten and held the key place so that Yuan Shao could not advance. The situation is clear, there is no room for manoeuvre, and a major change is not long in coming, and this is the time to surprise and win, and we must not miss it. ”

Therefore, Cao Cao was determined to continue to hold on to the standby and at the same time strengthen the defense, and ordered the task of logistics and supply to take the Ten Columns as one unit, shorten the distance between the front and rear of the transport team, and use the two formations to strengthen the escort to prevent the attack of the Yuan army. On the other hand, he actively sought and captured fighters, defeated the Yuan army, and soon sent Cao Ren and Shi Jian to intercept and burn thousands of grain wagons of the Yuan army, which increased the supply difficulties of the Yuan army.

Yuan Shao sent a cart to transport grain, and ordered Chun Yuqiong to lead 10,000 troops to escort it and accumulate it in Wuchao, about 20 kilometers north of Yuan's camp. Coincidentally, at this time, Yuan Shao's advisor Xu You defected to Cao Cao and suggested that Cao Cao's light troops surprise attack Wuchao and burn Yuan's army's baggage.

Xu You was one of Yuan Shao's earliest advisors, and followed Yuan Shao step by step to fight the world, but at the same time Xu You had a good relationship with Cao Cao.

After Cao Cao's defeat in Bianshui, he voted for Yuan Shao several times, and Cao Cao and Xu You met again, which provided a reason for Xu You to secretly help Cao Cao.

Xu You is greedy, and Yuan Shao can't be satisfied, but Yuan Shao's strength is so bullish, so who can satisfy Xu You? This person is very likely Cao Cao, Cao Cao gave Xu You money, and Xu You is the most staunch advocate of uniting Cao Cao in Yuan Shao's camp.

In the Battle of Guandu, Xu Yu suggested that Yuan Shao copy Cao Cao's rear in a roundabout way, which was obviously to put Cao Cao to death. It can be seen that each is its master, and the battlefield is ruthless, but Yuan Shao, who is constantly scheming, refused.

But Qi is here, Xu You made a strategy, Yuan Shao refused, Xu You can be forgiven for losing his temper, why did Xu You defect?

Tian Feng is particularly upright, Cao Cao attacked Liu Bei, he suggested that Yuan Shao sneak attack Xuchang, but Yuan Shao excused himself from being sick and did not send troops, which made the old gentleman angry, and in front of Yuan Shao, he poked the floor with a crutch fiercely.

It can be seen how strong his temperament is, so he has a fatal wound - a crime. If his strategy is not adopted, this old gentleman will be angry, but Yuan Shao's heart is not big, if he can see people playing temper in front of him, I guess he will not be surnamed Yuan, so he alienated Tian Feng.

Before the decisive battle, Tian Feng still tried to dissuade Yuan Shao from engaging in a decisive battle. Maybe Tian Feng is right, the tired enemy strategy of sticking to the danger and dividing the troops to plunder is correct, but Yuan Shao has been preparing for such a long time, everything is ready, and the arrow is ready to fly, how can he listen to Tian Feng's words and turn back? But this old gentleman was playing with his temper again, and he became even worse, Yuan Shao simply threw Tian Feng into prison.

The characteristics of the trial are loyalty and authoritarianism, and the weakness is inconsistencies. Feng Ji is a decisive person, but his weakness is stubbornness. What's more interesting is that Yuan Shao went south, Xu Yu and Fu Zhi served as staff officers, Chun Yuqiong and Guo Tu divided the military power granted by Fu Yu, and Feng Ji and the trial were responsible for staying in the rear.

Xu You is a veteran strategist under Yuan Shao's account, and he is also very sharp on strategic issues such as the value of the Son of Heaven. I didn't say that I had a strategic vision. The staff officers have chosen the right people.

Chun Yuqiong and Guo Tu are die-hard supporters of Yuan Shao and are loyal. They held military power, and Yuan Shao was very relieved. Every discipline is in charge of government affairs, and there will be absolutely no problems with these two people being in charge of the rear.

Xu Yu is greedy but not cured, greed is his personality characteristic, incurability is his Achilles heel, it is precisely because he is incurable and reckless, so there are people who have long been waiting to cure him. When Xu You was at home, he obviously couldn't cure him, but Xu You was working as a staff officer outside, and no one could hold him up when the sky fell at home. His relatives are lawless. During Xu You's outing, they still didn't know how to converge, and as a result, they were robbed of their homes by the loyal and upright trial and the rigid and self-righteous Feng Ji.

Xu You slipped out of Yuan Shao's camp, as a senior staff officer of Yuan Shao's headquarters, the middle and lower-level foot soldiers had no right to inquire about his whereabouts, so Xu You arrived at Cao Ying very smoothly. Cao Cao was at a loss for the battle situation in front of him, and he had already stripped off his clothes in the military tent, and he didn't really close his eyes for several nights, so he struggled like this.

The sergeant came to report that a spy of Yuan Jun was captured by the secret post outside the village, saying that the general's old friend Xu Yu had arrived. Cao Cao was pleasantly surprised, he was sleepy, he didn't even bother to wear shoes and socks, and rushed out of the camp barefoot, and his intuition told him that the savior had arrived.

Cao Cao dragged the visitor into the military tent barefoot, and did not let the close attendant Xu Chu follow up, but only ordered Xu Chu to get some simple wine and food, saying that he wanted to have a good conversation with his old friend all night, and said: "No one is allowed to come close to disturb, including Xu Chu, who hears a conversation, will be executed immediately." ”

Xu You put on a calm look at Cao Cao, looked at Cao Cao with a smile, and only heard Cao Cao laugh: "You are finally here!

As soon as Xu You sat down, he coldly threw Cao Cao a sentence: "Yuan Shao's army is powerful, how are you going to deal with it?

Cao Cao didn't care: "It's not much, it's enough for a year." ”

Xu You's face suddenly became serious: "Don't be kidding, say it again!"

Cao Cao's attitude also became serious: "To be honest, half a year." ”

Xu You stared at Cao Cao, with a smile on his face: "What's the matter? You don't want to defeat Yuan Shao?

Cao Cao's expression was solemn, as if he had made a major determination, his eyes swept outside the tent, and he lowered his voice: "I was indeed joking just now, in fact, there is only one month's food left, and I am anxious now." ”

Xu You sighed, knowing that he couldn't get Cao Cao's truth no matter what, so he simply opened the window and said something bright: "You are now alone in Guandu, there are no reinforcements outside, the military rations are exhausted, and now is your crisis." ”

This time it was Cao Cao's turn to be silent, Cao Cao was a person who understood, Xu You suddenly came to vote, entered the door without greetings, first pointed out that the battle situation was bad, and the words pointed directly at the military rations, this is the lifeblood of Cao Jun, since Xu You took the initiative to break it, there is no need for Cao Cao to answer, just wait for Xu You to continue.

Sure enough, Xu Yu knew more about the urgency of time, and he couldn't go around the circle: "Today, there are 10,000 Yuan Shao's baggage vehicles, stationed in Wuchao at night, and Chun Yuqiong, the chief general of the grain protection army, although he led five deputy generals and 10,000 cavalry; ”

With such accurate information sent to the door, Cao Cao was ecstatic in his heart, and he did not thank him, and then asked Xu Yu to rest in another account, and called Xu Chu to quickly inform the main generals and strategists in the army to come to the big tent to discuss matters immediately. After a while, everyone gathered to listen to Cao Cao's brief talk about the military situation, and they collectively opposed the dispatch of troops.

Everyone's reason is very simple: An old friend who has not met for more than ten years, and who is also a high-ranking staff officer in Yuan's army, suddenly brought such a major secret to surrender to Cao Cao when he needed it most, how could it not make people suspicious? Once Yuan Shao used a strategy, the whole army would be defeated quickly. The most obvious suspicion is that Yuan Shaoneng does not know that military rations are the lifeblood of the whole army? Can he not send elite soldiers to protect the grain? Even if Xu You sincerely came to surrender, everything is as he said, how can he deal with the 10,000-strong army of Chun Yuqiong and other six generals?

As for how many troops can be assembled and dispatched, everyone knows in their hearts, and it is absolutely impossible to exceed the number of the enemy's escort army, and this kind of risky battle, of course, it is best not to fight; at this time, Xun You spoke: "The opportunity must not be lost, the time will not come again, and now is the time to take a risky battle." ”

It's a pity that only Jia Xu is the only one who supports Xun You's opinion, these two people are actually not taking the risk to support Cao Cao's opinion, but understanding Cao Cao's current situation, not taking this risk, it is tantamount to waiting for him to die soon.

Cao Cao categorically supported the opinion of the minority, and all the generals left only Cao Hong and his advisers to stick to the camp, and the rest of the generals, including Xu You, who volunteered to lead the way, immediately dispatched with Cao Cao himself to lead the army, all under the banner of Yuan's army, and strive to reach Wuchao before dawn; how many mobile troops could be dispatched? Half of the infantry and half cavalry, a total of 5,000 soldiers.
