During the Great War of Yuan Cao Guandu, why did the big warlords in various places not move?

There have been many wars in the Three Kingdoms period, among which there is no lack of some classic battles to win more with less, the battle of Guandu is a war between Yuan Shao and Cao Cao, and finally Cao Cao with more than 30,000 troops to beat Yuan Shao's more than 100,000 troops, won the victory of this war, the battle of Guandu is also one of the typical battles with less to win more, is an example of a war that has to be mentioned in the Three Kingdoms period. When the conflict broke out between Yuan Shao and Cao Cao, the big warlords across the country did not participate in the struggle between the two of them because of the civil war or because of the unintentional war. <>

The Eastern Wu Civil WarWhen the war broke out between Cao Cao and Yuan Shao, it was a particularly unstable time for the Eastern Wu regime. As a very important historical figure in the history of Eastern Wu, Sun Ce was good at arranging troops, and he was very strong, Cao Cao and others were very jealous of him, but on the eve of the outbreak of the Battle of Guandu, Sun Ce was assassinated, which eliminated a big trouble for Cao Cao. After Sun Ce was assassinated, Sun Quan took his place, but Sun Quan was busy quelling some rebellions against him at that time, so when faced with Yuan Hao's joint request, he chose to refuse, and he did not participate in the war between the two.

When Cao Cao's biggest threat, the Jiangdong region, had no time to take care of their war, Cao Cao's southwest was also in a situation of two tigers contending. The two generals in the southwest are Zhang Lu and Liu Zhang, the two of them are incompatible, and there are often some frictions, Zhang Lu naturally has no intention of caring about the war between Cao Cao and Sun Quan, because his first priority is to defend against Liu Zhang's attack, and Liu Zhang's own situation is also very bad, and internal conflicts often break out within his camp, so he is facing internal and external troubles, and has no energy to participate in the war between Yuan Shao and Cao Cao. <>

Insufficient troopsJingzhou has always been a place that several rulers have been fighting for during the Three Kingdoms period, and Jingzhou was initially controlled by Liu Biao. Although Jingzhou seems to be a battleground for soldiers, it also has many internal problems. When Liu Biao faced the war that broke out between Yuan Shao and Cao Cao, he rejected Liu Bei's request to flank Cao Cao, because Liu Biao himself was dependent on the internal clan, and he also needed to guard against the threat of Jiangdong and Eastern Wu to them, he very much needed a team for defense, and there was no extra force to flank Cao Cao in the north, and Liu Biao himself did not like war, so the big warlords in various places did not participate in the battle of Guandu at that time.

During the Battle of Guandu, Cao Cao and Yuan Shao were the two largest warlords at that time, and the other warlords did not have the ability to compete with them.

At that time, the various warlords were waiting to see what happened, because Yuan Shao was the most powerful at that time, and no one would believe that Cao Cao could defeat Yuan Shao, and if he went to fight Cao Cao, it would probably cause Yuan Shao's dissatisfaction and resentment.

The strength of both sides of the battle of Guandu was relatively strong at that time, and if they attacked rashly, the two sides might turn around and destroy themselves first, and the gains outweighed the losses, so it was better to watch the fire from the other side.

<> "How did Cao Cao destroy Yuan Shao in the Guandu War."

The Three Kingdoms at the end of the Han Dynasty, as a troubled era, wars are frequent, and there are many famous battles, today, we review another major war that occurred before the Battle of Chibi that was decisive for the general trend of history - the Battle of Guandu. These two great battles were the two most important battles in the three major battles of the Eastern Han Dynasty.

1.Campaign background.

In the fourth year of Jian'an (199 A.D.), Yuan Shao destroyed Gongsun Zhan, occupied all four states, more than 100,000 people, its momentum was extremely prosperous, and the spirit was extremely high, and he wanted to go south to attack Xudu. Cao Cao's subordinates mostly thought that Yuan Shao was invincible. But Cao Cao knew that Yuan Shao had a strong and middle-class cadre on the outside

Ambitious and talented, temperamental and courageous; Treat people arrogantly but without majesty; Although there are many troops, they do not know how to deploy; The generals are arrogant and keep ordering. Based on this, Cao Cao thought that he could fight with Yuan Shao.

2.Brief passage.

In August of the fourth year of Jian'an, Cao Cao's troops entered Liyang, sent the general Zang Ba into Qingzhou, and captured Qi (Linzi), Beihai (Changle), and Beihai (Yishui) to block the route of Yuan Shao's attack on Xudu from the east. At the same time, he sent troops to Bantun and Yanjin, the fortress of the Yellow River, to block Yuan Shao's route to cross the river.

In September, Cao Cao returned to Xudu and sent troops to garrison Guandu.

In November, Xiliang Zhang Xiu surrendered to Cao Cao and resisted Yuan Shao, and Cao Cao has been worry-free in the northwest since then.

In December, Cao Cao went to Guandu in person.

The fifth year of Jian'an (200 AD).

In the first month, Liu Bei rebelled against Cao Cao, and Cao Cao raised troops to recruit troops and broke it.

In February, Yuan's army besieged Liu Yan with the White Horse soldiers, and Cao Cao led his troops to rescue and relieve the siege. This battle killed Yan Liang. Immediately afterward, Yuan's army pursued Cao Cao to the south of Yanjin. Cao Cao Yixiang searched Xun You's strategy to lure the enemy, defeated Yuan Shao again, and killed Wen Chou.

In August, Cao Cao and Yuan Shao camped at Guandu to confront each other. Yuan Shaobing had little food and wanted to retire. After Xun Yu's persuasion, he gave up retreating and waited for the time to move.

In October, Yuan Shao transported grain and sent Chun Yuqiong to escort him. It coincided with the surrender of Yuan Shao's strategist Xu Yu to Cao Cao, offering advice to Cao Cao and attacking Chun Yuqiong. Cao Cao complied and broke Chun Yu Qiong. Yuan Shao's general Zhang He Gao heard the news and surrendered to Cao Cao. Yuan Shao was defeated.

In the Battle of Guandu, Yuan Shao was defeated by Cao Cao. Because of this battle, Yuan Shao was criticized. Everyone criticized Yuan Shao's strategy and tactics, believing that his failure was caused by not accepting the good words and persuasion of Fu Zhu and Tian Feng.

It seems that Yuan Shao would be able to defeat Cao Cao as long as he accepted the advice of Fu Zhu and Tian Feng.

During the confrontation between the two sides in Guandu, it was Cao Cao who actually put more pressure on him. At that time, many of Cao Cao's subordinates defected to Yuan Shao Dakai, and many secretly colluded with Yuan Shao. After the Battle of Guandu, a box and letters colluded between Cao Cao's men and Yuan Shao were discovered, and Cao Cao ordered them to be burned.

Cao Cao said that under the circumstances at that time, I didn't know if I could be spared, let alone others. It can be seen how difficult Cao Cao's victory was.

Therefore, Cao Cao's victory was not due to the difference in strength between the two sides, but from the use of strategy. In Zhuge Liang's words, it is "not only the heavens but also the people". And this conspiracy is Yuan Shao's internal problem.

There are many doubts about the battle of Guandu.

For example, Xu You's behavior is very suspicious. And Cao Cao's ability to anticipate things like a god, grasp Yuan Shao's fatal weakness, and repeatedly and accurately attack Yuan Shao's grain route is even more suspicious. There is no clear record of these in history, and we can only find the doubts in the middle of the Spring Hall.

The main reason for Yuan Shao's defeat was the abolition of the frustration and the detention of Tian Feng before sending troops. Before a big war, why Yuan Shao cut off his femur is a mystery. However, we can judge from this that as long as Yuan Shao launched an attack on Cao Cao, these contradictions would erupt, which is even more suspicious.
