When Liu Bei was on Guan Yu s Northern Expedition, what were the three main reasons for not moving?

The three main reasons are that the time is relatively rushed, followed by the disparity in strength, and finally the strategic reasons, the battle of Hanzhong, it seems that Liu Bei won, in fact, Liu Bei got Hanzhong is a deserted empty city.

The first reason is that Liu Bei has just finished the battle of Hanzhong and is still recovering.

The second reason is that Liu Bei has a long road and failed to receive Guan Yu's rescue news in time.

The third reason is that Guan Yu is too relieved.

The first is because although he obtained the entire territory of Hanzhong, Cao Cao took away a large number of people and needed to defend Hanzhong, the second is because Liu Bei was seriously consumed in the battle of Hanzhong and was unable to respond to Guan Yu in a short time, and the third is because Liu Bei thought that Guan Yu could retreat even if the attack failed, but he didn't expect the sneak attack of Eastern Wu.

1, Guan Yu's Northern Expedition did not go through Liu Bei's consent, because Guan Yu was arrogant and uninhibited, seeing Liu Bei triumphant all the way in Xichuan, and thinking that Eastern Wu was all rats, it was not worth worrying, and Jingzhou's soldiers had enough food and grass, so he sent troops without authorization to break Cao Wei alone, such a move Guan Yu did not notify Liu Bei. In other words, when Guan Yu flooded the Seventh Army, Liu Bei didn't even know what was happening in Jingzhou.

2, Guan Yu failed too quickly, and when he failed, he sent soldiers to ask for help from Liu Feng and Meng Da, why didn't he go to Chengdu for help? It can be seen that Guan Yu never paid attention to Liu Bei about these battles, and he didn't even think that he would lose, nor did he consider letting Liu Bei send some troops to wait for support near Jingzhou. This entire attack process was completely planned by Guan Yu himself, and he never thought that he needed reinforcements to deploy.

3. When Guan Yu defeated Maicheng, Liu Bei probably thought that Guan Yu was fighting hotly, and Liu Bei also believed in Guan Yu's ability, for Liu Bei, Guan Yu's war was more laissez-faire, but he didn't care about Guan Yu and let him fight by himself, Liu Bei believed that the result would definitely be good. Have you ever seen Guan Yu defeated before? Kill Yan Liang, Zhu Wen is ugly, and his majesty is unstoppable, for such a general, how could Liu Bei have thought that he would fail and be so fast.

4. When Liu Bei knew that Guan Yu was defeated, Jingzhou was already completely under the control of Eastern Wu, and Guan Yu was also... At this time, it no longer makes any sense to send reinforcements, which is equivalent to directly declaring war on Eastern Wu and attacking Jingzhou, which is not within the scope of sending troops to support. Therefore, Liu Bei could only fight hard and wait for the opportunity, so there was the Battle of Yiling.

I didn't expect Guan Yu to lose at the hands of Lu Meng After all, Lu Meng is not a veteran on the battlefield

1. Long distance.

2. At that time, Guan Yu was in a state of victory.

3. When Guan Yu had an accident, it was too late because of the long distance.

4, Liu Bei didn't expect him to lose so quickly.

Of course, the generals of Cao Cao's camp can compete with Guan Yu, such as Xiahou Yuan, Xiahou Chun and Cao Ren, etc., the official positions and ranks of these people are comparable to Guan Yu, they all have the ability to fight with Guan Yu, but the ability of these three people is not as strong as Guan Yu, if they fight alone and lead troops to compete with Guan Yu, then they will not be able to benefit. Let's briefly introduce the specific situation!

First, when Guan Yu launched the Battle of Xiangfan, Cao Ren was a little unable to resist. Cao Ren is a famous general defending the city in Jingzhou, he is famous there, and he can do a particularly good job of defending the city, and no one can attack it, but when he met Guan Yu, the situation has declined a little. In the north of Fancheng, the geographical location is relatively low, but Cao Ren did not realize this, he only prepared a small boat here, and did not consider the consequences of Guan Yu's water attack at all, facing a senior naval general, can you imagine what the result of Cao Ren will be?

Guan Yu was famous in this battle, not only killed the generals of the Cao army, but also made the food and grass in the city scarce, Cao Ren really couldn't stand it, and was particularly flustered at that time, and finally could only ask the big boss Cao Cao for help.

Second, if Xiahou Chun and Xiahou Yuan fought against Guan Yu, what would be the outcome? Guan Yu is a very capable general, he leads the team to fight very strongly, and his most powerful ability is to lead the naval army to fight, his naval combat experience is extremely rich, as long as 10 years, if Xiahou Chun and Xiahou Yuan fight Guan Yu in the Northern Plain region, then they may defeat Guan Yu, but if it is in the Jingzhou battlefield, then their combat ability is far inferior to Guan Yu.

Three, apart from Xiahou Chun, don't Xiahou Yuan and Cao Ren have any other generals? Of course, there are so many generals under Cao Cao, and there are countless talents, and the famous generals at that time are: Cao Hong Xu Huang, Le Jin, Cao Zhen, Yu Ban, Cao Xiu, Zhang Liao and so on.

These people were able to take charge of the battle alone, but at that time, the morale of Cao's army was frustrated again and again, and Cao Cao did not send these generals to help, so the battle was a complete failure.

To a certain extent, Cao Cao's many reinforcements proved that Cao Ren was unbearable, Xiahou Xuan, Xiahou Yuan, and Cao Ren, who led the troops alone, were not Guan Yu's opponents, and Cao Cao's other generals did not have the strength to lead the corps to fight, and he was frustrated one after another and lost his fighting spirit.

No one can stop them, because they are all very strong, and they are very powerful in martial arts, few people can defeat them, and the people under them are also afraid of them, and the people under them cannot stop this kind of thing.

The momentum of the Northern Expedition was very large, the combat effectiveness of the army was very strong, and the army under Cao Cao did not have enough strength to resist them.

That is true. In 217 AD, Liu Bei's army went north, fought Cao Cao in Hanzhong for two years, and achieved some victories (this was when the Dingjun beheaded Xiahou). In 219, the battle ended, and Liu Bei ascended to the throne of Hanzhong.

In this situation of high morale, Guan Yu raised troops and went north. But at this time, Liu Bei had just finished a big battle, and it was said that to the extent that the women had to be requisitioned and shipped grain, so naturally they couldn't finish the fight once and fight again.

The root cause is that Liu Bei's foundation is too thin and he does not have enough strength to support the big war on both fronts at the same time. couldn't do what Zhuge Liang Longzhong said to Li, and the two roads went north together. After all, Longzhong's plan was not fully realized, Jingzhou was not fully obtained by Liu Beifang, and although Liu Bei in Hanzhong got it, the population was taken away by Cao Cao.

Liu Bei and others didn't know that Guan Yu was attacking Xiangyang, and Guan Yu launched the Battle of Xiangfan without authorization, so they didn't take the opportunity to go on a northern expedition.

Because at this time, Shu Han continued to rest after the Battle of Hanzhong, and the army suffered too much loss and needed to be replenished, plus the ordnance, grain, and grass needed to be prepared, so there was no strategy for Guan Yu's Northern Expedition to the Central Plains.

Because Liu Bei and Zhuge Liang's forces were relatively weak, coupled with the Northern Expedition facing the powerful Cao Cao, there was no chance of victory at all.

Liu Bei didn't want to send troops when Guan Yu launched the Battle of Xiangfan, but he really didn't have troops to deploy them. Guan Yu launched the battle of Xiangfan in 219 AD, this year is also the end of the battle between Liu Bei and Cao Cao in Hanzhong, Cao Cao and Liu Bei basically used their housekeeping skills in the battle of Hanzhong, although it ended in Liu Bei's victory, but the price paid was very large.

The Battle of Hanzhong can be said to be a life-and-death battle between Wei and Shu, and the duration of this war is also extraordinarily long, a full two years. This means that during the war, any supplies must be close to the fighters in the front, and most of the labor force is required to be recharged to the front line, and the two-year war is a catastrophe for a country, not only testing the strength of the country, but also testing the fate of a country. After two years of hard fighting, Shu won the final victory by a slight advantage, as the war country of this war, Liu Bei had the capital to be the emperor, but the loss of this war to Shu was indeed immeasurable.

In the description of this war in the history books, there is a particularly "conspicuous" sentence that "men should fight, women should be lucky", simply put, the men of the entire Shu Kingdom went to the front line to fight, and the people responsible for carrying grain and grass materials were women, so after experiencing this war, Shu was really "out of ammunition and food", and later when Guan Yu launched the Battle of Fancheng, although Liu Bei wanted to help Guan Yu, he was powerless. At that time, what Liu Bei and Zhuge Liang said to Guan Yu roughly meant that they wanted Guan Yu to watch it himself, and he was no longer able to help you. Liu Bei and Zhuge Liang didn't know how correct it was to launch the Battle of Xiangfan at this time, but Liu Bei's family did not support Liu Bei to aid Guan Yu.

In the early stage of the Battle of Xiangfan, Guan Yu defeated Cao's army like a god of war, but in the end, Cao Cao and Sun Quan united, and Sun Quan attacked Guan Yu's hometown Jingzhou, resulting in Guan Yu's defeat and Maicheng being killed。The Battle of Xiangfan can be said to be a turning point for the Shu Kingdom, after which the Shu Kingdom became weakened, and since then the Shu State has begun to go to extinction.

Guan Yu knew that Liu Bei had such thoughts, so he made preparations in advance, Liu Bei was not completely sure of victory, so he did not fall ill.

Shu Han's national strength is not so sufficient, Guan Yu already needs a lot of grain and grass to launch the battle of Xiangfan, and logistics support, and the remaining grain and grass logistics of Shu Han are no longer enough to support Liu Bei to take the opportunity to send troops again.

Because Liu Bei had just finished Hanzhong at that time, he needed time to cultivate, and he couldn't come out at all.
