Cao Cao became famous in one fell swoop because of this war, which laid the foundation for unifying the North.
In June of the fourth year of Jian 'an (199), Yuan Shao selected 100,000 elite soldiers and 10,000 war horses in an attempt to attack Xudu South, and the battle of Guandu started.
Cao Cao fought a decisive battle with Yuan in Guandu (now northeast of Zhongmou, Henan), with about 20,000 troops.
When the two sides were deadlocked, Xu You, the counselor, abandoned Yuan Shao and defected to Cao Cao, offering Cao Cao a surprise attack on Yuan Jun's granary in Wu Chao (now Fengqiu West, Henan Province), thus defeating Yuan Jun's main force and winning the battle of Guandu.
During the battle of Guandu, the two armies were at loggerheads on the Yellow River for more than a year, and many thrilling stories happened. If any detail is not handled properly, the balance of the war will tilt, and it is really difficult to say who wins or loses.
There are too many inevitable factors for Yuan Shao's failure.
There are too many accidental factors in Cao Cao's victory.
However, inevitability is mixed with contingency, which confirms inevitability.
Historians have summed up too many valuable experiences and painful lessons, and all of them have wonderful comments.
However, Haichen thinks that Yuan Shaozhi's defeat is on two people, one is too serious and the other is not serious!
Knowing people, employing people and controlling people are the skills of strategists and commanders.
Yuan Shao's industry can be so big, and it is reasonable to have extraordinary skills in knowing people, employing people and controlling people.
Actually, it is not. He grew up in a big organization. He was still a playboy when he led troops to fight. He only cares about his feelings and everything goes with his feelings.
Xu You has a long history. When I was young, I made friends with Yuan Shao and Cao Cao.
A person who grew up playing should know a lot.
Yuan Shu's evaluation is: "Xu Ziyuan is a vicious person with impure sexual behavior."
Yu Xun's comment is: "Xu You died of greed."
Luo Guanzhong concluded: "I can laugh at a friend of Nanyang, and I will respect the princes with my chest. If you don't think of Cao Cao as a bear and tiger, you will get Jizhou only if you think of me. "
In a word, Xu You is a fierce, lewd, impure, greedy and short-sighted fanatic, a fanatic with little ambition.
Unlike Mi Fei, Kong Rong and Yang Xiu, he is fundamentally different. He only pays attention to immediate interests and never considers the long term. His loyalty is just a joke.
To put it bluntly, the goods are old and dishonest, and they are talented and unscrupulous speculators
For this kind of person, use it carefully if you can, and never let him go if you can't use it.
Cao Cao understood this truth after a little thinking and knew how to do it.
Yuan Shao has always been aware of it, but he knows everything too late.
Xu You was Yuan Shao's counselor. When Yuan Shao attacked Gongsun Zan, annexed Youzhou, owned Jizhou and other four states, and became the most powerful vassal in the north, he was regarded as one of the most important advisers.
In the battle of Guandu, Xu You gave Yuan Shao an idea:
"Cao Cao serenade, will inevitably concentrate on resistance, many guards will be empty.
If a light cavalry is sent to raid Xudu, Xudu can be captured.
If he doesn't break up at once, he will be exhausted because he can't take care of both ends, and Cao will be defeated. "
This is a fatal trick to avoid reality and avoid emptiness. If this move is implemented, Cao Cao will have nothing.
It happened that such a good plan came from Xu You. How can armed Yuan Shao adopt it?
In Yuan Shao's view, it is only a matter of time before Cao Cao's downfall, and there is no need to go to so much trouble.
This is very regrettable for Yuan Shao and very lucky for Cao Cao.
Just then, my family gave Yuan Group a test question to test Yuan's comprehensive management level.
Someone in his family actually broke the law, so Shen Pei, who stayed in Yecheng, arrested his family and put them in prison.
This brother Shen Pei is too serious. Family members of important leaders make some mistakes. Let's educate them and arrest them without saying anything.
I also blame Yuan Shao for caring only about the war, paying too little attention to political education, and failing to teach cadres to set up the idea of playing a game of chess behind the front line.
Xu You commanded the war at the front line and held the core lifeline of Yuan Group-the specific deployment of troops. How can you move his people in Shen Pei?
Even if you ask Yuan Shao for instructions, or ask Yuan Shao to find a way to stabilize Xu You, it's ok to just say good ideas and be unprepared, which will make a big mistake.
We should combine principle with flexibility in doing things, instead of shouting slogans for show, we must put them into action.
Shen Pei is too serious, too principled and inflexible.
Xu You was very angry after learning about it, and the consequences were extremely serious.
This product is old and not serious. I've racked my brains to give you a brilliant plan of Yuan Shao. Forget it if you don't adopt. Actually, I still have people after my family. If I get it off again, my life will be ruined.
I don't want to stay here, but there are people waiting in line outside.
People who are not serious will naturally not have serious ideas.
The goods didn't go to Yuan Shao to reason, let Yuan Shao order the release, and went to Cao Cao without saying anything.
Also, Yuan Shao was the commander in chief, and Shen Pei caught Xu You's family in the rear. It is impossible for him not to know what he didn't say in time, which made Xu You more sad and desperate.
It was originally a small problem, but it was infinitely magnified in an extraordinary period. Neither Yuan Shao nor Xu You played by common sense.
Yuan Shao was insensitive during the sensitive period, while Xu You was completely insensitive to the villain's heart, which led to excessive sensitivity-he was a talented villain, so don't expect him to understand the overall situation.
Later, as we all know, Xu You pointed out the lifeblood of Yuan Shao Group to Cao Cao.
Cao Cao personally led 5000 elite cavalry to raid the Wu Dynasty and burned Yuan Shao's granary. Yuan Shao did not cross the river to escape.
Therefore, Shen Pei was too serious when he was sensitive, which eventually led to Yuan Shao's defeat in Guandu.
As for this seriousness, how many benefits are hidden behind it? Haichen sold it and decomposed it later.
Can it be said that Yuan Shao won the battle of Guandu and lost Shen Pei?
