What caused Yuan Shao to lose the battle of Guandu at that time?

Reasons for Yuan Shao's failure: Yuan Shao is indecisive. At the beginning of the war, Cao Cao wanted to destroy Liu Bei stationed in Xuzhou. Many of Cao Cao's men reminded me. "Lombardi is fighting with your majesty. Now you have a fight with Yuan Shao. Cao Cao said, "Your Majesty threw Yuan Shao aside and attacked Liu Bei eastward. Cao Cao said, "Liu Bei is a great man. If we don't take this opportunity to destroy him, he will definitely become a dangerous person. " Guo Jia agreed with Cao Cao and said, "Yuan Shao is an ambitious man", but he is slow to act and indecisive in dealing with problems. When Tian Feng heard this, he said to Yuan Shao, "Now Cao Cao is leading an army to invade Liu Bei. We should take this opportunity to besiege Cao Cao. " Yuan Shao said, "My son is ill, and I have no intention to think about it. Cao Cao defeated Liu Bei and returned to Guandu. Yuan Shao did nothing. In this regard, Tian Feng, Yuan Shao's aide, stabbed the people on the ground with a cane and said, "Such a good opportunity is lost because of the child's illness!"

Yuan Shao lacks decision-making ability. The decisive factor in the battle of Guandu was that Cao Cao burned down Yuan Shao's lair granary. Xu You, Yuan Shao's counselor, left Yuan Shao to fight against Cao Cao because Yuan Shao could not meet his demands. He suggested that Cao Cao set fire to Yuan Shao's black nest granary. For the arrival of Xu You, Cao Cao's camp suspected that he was undercover. Now it is suggested that Cao Cao ambush the black nest granary, which makes people doubt Xu You's intention. Because Xu You is, after all, Yuan Shao's counselor, and now he suddenly comes to make suggestions, people have no reason not to doubt his intentions. Therefore, Cao Cao thought that Xu You meant no harm, and his counselors Xu You and Jia Xu also thought that Xu You's words were credible. With the support of Xu You and Jia Xu, Cao Cao personally led people to raid the black dens. Judy, Yuan Shao's counselor, suggested that Yuan Shao send Jiang Wei to guard here to prevent Cao Cao from attacking here. Yuan Shao did not adopt it. The Black Nest is only forty miles away from Yuan Shao's camp, and Cao Cao's sneak attack succeeded. Cao Cao burned Yuan Shao's black nest granary, and Yuan Shao was defeated.

Yuan Shao has no bearing. At the beginning of the war, Tian Feng, Yuan Shao's counselor, suggested to him, "Cao Cao is good at fighting, but his troops are not as good as ours. We should have the idea of fighting for a long time and continue to send troops to harass Cao in Henan. If Cao Cao moves to the left, we will attack him from the right. If Cao Cao wants to rescue the right side, we will attack his left side. If this continues, we will kill Cao Cao in two years. " Yuan Shao was defeated in the battle of Guandu, so he killed Tian Feng for fear that Tian Feng would laugh at him. At the beginning of the war, many Cao people worried about defeat and wrote to Yuan Shao in succession to seek a way out. After the war, Cao Cao discovered these secret letters written by Yuan Shao to Cao Cao. Cao Cao lost it without even looking. Some people think that these people should be held accountable. Cao Cao said: "At the beginning of the war, even I didn't doubt it, let alone others." To sum up, Cao Cao is not as powerful as Yuan Shao at that time, but in the long run, he will surely turn defeat into victory!
