When Zhuge Liang sent troops to attack Cao, the national strength was empty, why didn t Sun Quan sen

Since Zhuge Liang's first dispatch of troops was secret, and the next few dispatches were all partial offense and defense, Shu itself did not do its best, and Wu certainly would not take the initiative to cooperate.

Sun Quan responded to Zhuge Liang's last Northern Expedition, and the imperial driver personally conquered Hexi, but was defeated by the governor of Yangzhou.

Zhuge Liang mobilized a large number of troops, and in Wuzhang Yuan Tuntian, and the Wei State confronted for a long time, Sun Quan seized the opportunity and divided his troops into three ways to attack Wei.

However, Sima Yi did not move, Zhuge Liang only restrained the Guanzhong army of Wei, Cao Rui assigned 20,000 people to support Sima Yi, and he sat in Luoyang, Wei was not "empty of national strength".

Sun Quan's previous solo action, or this time with the Shu army, the reason for the failure is the same, Eastern Wu is good at the water army, in the Lujiang River, the battle advantage in the Xukou is obvious, in Hefei City, Jiangxia City, the battle is at a disadvantage. The Wu army did not have a large number of war horses, and field battles and siege battles would fall into passivity, so many northern expeditions returned in vain.

If Sun Quan sends troops to attack Shu, it is equivalent to helping Cao Wei relieve the siege, and the result is that the Shu-Wu alliance will break down, not to mention that if Shu Han is destroyed, Cao Wei will turn his gun and attack Wu. It was not that Sun Quan had no ambition to cut down Shu, but that the situation at that time did not allow him to do so. Because there were many internal contradictions in the ruling class of Eastern Wu, and when Zhuge Liang attacked Wei, it was already in the late Three Kingdoms, and Cao Wei's national strength was obviously stronger than that of Shu Han and Eastern Wu, so only Shu Han and Eastern Wu jointly resisted Cao.

In fact, Eastern Wu is the most promising of the Three Kingdoms to unify the world, and the strategic policy formulated by Lu Su for Sun Quan at that time was to recuperate, unite Liu to resist Cao, watch the tiger fight on the mountain, and collect the power of the fishermen, so that Shu Han and Cao Wei could sweep the world if they were both defeated. It's a pity that Sun Quan didn't follow Lu Su's strategic policy, and there was a war between Jingzhou and Shu Han for a single Jingzhou, and the result was that Shu Han's vitality was greatly damaged, and Eastern Wu suffered heavy losses.

The Sun-Liu alliance is actually not as stable as imagined, and when sending troops, they are afraid that they will be killed.

Zhuge Liang thought that Fa Zheng could stop Liu Bei's expedition to Sun Quan.

There is such a passage recorded in the Chronicles of the Three Kingdoms: Liu Bei and Cao Cao fought a battle, and the Shu army could not be defeated, so they should retreat quickly, but Liu Bei was red-eyed and did not retreat in a desperate battle, and no one dared to come forward to advise.

At this time, the arrows rained down, smashing the Shu army formation, Fa Zheng stepped a few steps, blocking in front of Liu Bei, Liu Bei said: "Filial piety to avoid arrows." Fa Zheng said

Lord, you dare to stand calmly in front of the arrows, let alone my rotten life? Liu Bei was anxious, afraid that Fa Zheng would make a mistake, so he had to retreat with the army. See, this is Fazheng, ruthless, decisive, accurate in judging human nature, and knows Liu Bei's weaknesses.

Planned to kill Xiahou Yuan.

In front of Dingjun Mountain, Fa Zheng took the strategy of attacking the east and the west, leading Xiahou Yuan to rescue Zhang He and guard the antlers, and then Huang Zhong was ordered to take the camp step by step, kill Xiahou Yuan, and occupy Hanzhong County in one fell swoop. After Cao Cao learned about this, even he praised Fa Zheng's strategy.

This is the real Fazheng, as realistic as Jia Xu, who does not believe in any false name, who goes out openly, who will be avenged, who has clear grievances, sometimes cruel, who makes accurate judgments, and who is decisive in killing the first person, with Jia Xu's darkness and Guo Jia's inspiration.

Judging from the above deeds, Fa Zheng's persuasion played a great role in Liu Bei's decision-making, if he can live for a few years, maybe he can persuade Liu Bei to attack Eastern Wu, as Zhuge Liang said, even if he can't persuade him, he will definitely not let Shu suffer a fiasco of Yiling!

Zhuge Liang's experience

Zhuge Liang (181 - October 8, 234), the name Kongming, the name Wolong, Langya Yangdu (now Yinan County, Linyi City, Shandong Province) people, the prime minister of the Shu Han Dynasty during the Three Kingdoms period, the politician, military strategist, inventor, and writer of ancient China.

Zhuge Liang went to Jingzhou with his uncle Zhuge Xuan in his early years, and after Zhuge Xuan's death, Zhuge Liang lived in seclusion in Longzhong. Zhuge Liang proposed to Liu Bei to occupy Jingzhou and Yizhou, and unite with Sun Quan to fight against Cao Cao's "Caolu countermeasures" (one said that Longzhong was right), Liu Bei successfully established the Shu Han regime according to Zhuge Liang's strategy, and formed a three-legged trend with Sun Quan and Cao Cao.

In the first year of Zhang Wu (221), Liu Bei proclaimed himself emperor and appointed Zhuge Liang as prime minister. After Liu Chan succeeded to the throne, Zhuge Liang was named the Marquis of Wuxiang and led the Yizhou pastor. Be diligent and prudent, handle political affairs in person, and reward and punish them strictly; Alliance with Soochow to improve relations with various ethnic groups in the southwest; We should implement the policy of tuntian and strengthen war preparedness.

Five northern expeditions to the Central Plains failed to achieve the goal of reviving the Han Dynasty. In the twelfth year of Jianxing (234), he died of illness in Wuzhangyuan (now Qishan, Baoji City, Shaanxi Province) at the age of 54. The later lord Liu Chan was posthumously known as the Marquis of Loyalty, and later generations often called the Marquis of Wu.

Huan Wen of the Eastern Jin Dynasty was posthumously crowned as the king of Wuxing.

First of all, you need to know that the reason why the Three Kingdoms existed for decades was because Wei was strong, and the world accounted for seven points out of ten, and the population also accounted for eight points. During the period of six out of Qishan, Dongwu also responded several times.

Assuming that the assumption is true, during Zhuge Liang's Northern Expedition, Eastern Wu and Wei concluded an alliance and then sent troops from Jingzhou to attack Yizhou, there is a high probability that Shu Han will be destroyed, Zhuge Liang is not in a hurry to return to the division, and it is possible that because Shu Han perished in the hands of Eastern Wu and led troops to join Cao Wei, and then even if Eastern Wu occupies Yizhou, it will be involved in the strength of the Western Expedition because of the fact that the people of Yizhou are in Liu, and Cao Wei will definitely send troops in the face of such a good situation, so that the strength of Eastern Wu will be gone.

Therefore, during the Northern Expedition of Shu Han, if Eastern Wu took advantage of the fire to rob, it would actually be self-defeating.

There should be this consideration, the overall strength of Wei at that time was stronger than that of Shu Han and Eastern Wu. At that time, the international pattern had already formed a strong trend. Sun Quan is not an ordinary person, he still has his own set.

Cao Cao also said back then that he should be like Sun Zhongmou when he gave birth to a son! This is not a disparagement, but an affirmation of him. Of course, there is still friction between Shu and Wu, but it is not like the Romance of the Three Kingdoms!

Soochow also has its own considerations, and is developing the Jiangnan area! That's all! History sometimes doesn't have so many ifs!

Again, I would like to add some personal reasons for the following:

1.In the situation of the Three Kingdoms, if you attack Shu Han and defeat Shu Han, but after that, the strength of Eastern Wu will not have the confidence to argue with Cao Wei.

2.Shu Han has geographical advantages, easy to defend and difficult to attack, and Eastern Wu will not take this risk easily.

3.In the three-legged situation at that time, instead of taking the initiative to take risks, it is better to sit on the mountain and watch the tiger fight, regardless of them.

4.Whether it is ancient or modern, if you want to start a war, you need to have a proper reason (in fact, it is an excuse), otherwise you will not get the support of the people.

Because at this time, although Zhuge Liang went to the Northern Expedition, they still left a lot of troops in Shu, if Sun Quan took the opportunity to attack Shu at this time, they themselves would also suffer certain losses, and this practice would also be looked down upon by other countries, and they might be crusaded.

1.The first Northern Expedition was built in the spring of the sixth year of Shu Han Jianxing, and the First Northern Expedition failed due to the loss of Ma Tan's street pavilion and was defeated by Zhang He. At this time, Soochow sat on the mountain and watched the tiger fight.

2.In the winter of the same year, the second Northern Expedition killed Wang Shuang, the general of Wei, and Zhuge Liang withdrew due to lack of food and clothing. At this time, the Battle of Shiting broke out in Eastern Wu and sent Lu Xun to defeat Cao Xiu, the general of Wei.

It can also be regarded as a small fight, and the side symbolically supports the Shu Kingdom. 3.The third Northern Expedition was built in the spring of the seventh year of Shu Han, and Shu Han took Wudu and Yinping two counties.

This year, Sun Quan of Eastern Wu was busy claiming the emperor. 4.The Fourth Northern Expedition was built in Shu Han for nine years, and Zhang He was killed, but he retired due to the exhaustion of food.

At this time, Sun Quan of Wu was busy crusading against the barbarian rebellion. Since Liu Bei's death, Cao Wei began to devote his main energy to dealing with Sun Wu.

Mainly because Sun Quan hoped that after Zhuge Liang's Northern Expedition and Wei were defeated, Wu would reap the benefits of the fisherman, but he didn't expect Zhuge Liang to be able to defeat Wei, so Sun Quan did not take the opportunity to attack the rear of Shu.

The last reason is that when Zhuge Liang carried out the Third Northern Expedition, it was when Sun Quan was proclaimed emperor in Eastern Wu, and Sun Quan had just established power at this timeThere is not much time to send troops to help Zhuge Liang.

Sun Quan's Northern Expedition was earlier than Zhuge Liang, and as soon as Cao Pi died, he attacked Jiangxia without success. And Zhuge Liang was stationed in Hanzhong.

Zhuge Liang's first Northern Expedition, Sun Wu was quelling the rebellion in Poyang County, but failed to cooperate.

Zhuge Liang's second Northern Expedition was carried out when Eastern Wu launched the Battle of Shiting, but it was blocked by Chen Cang.

Zhuge Liang's Third Northern Expedition was a counterattack to Cao Wei's attack. Sun Quan took the opportunity to become emperor.

Zhuge Liang's Fourth Northern Expedition, the main force of Eastern Wu cooperated with the suppression of the Wuxi rebellion. Lu Xun cooperated with the attack on the Wei Lujiang River, but because the news leaked, the enemy set up an ambush and took the initiative to retreat.

Zhuge Liang's fifth Northern Expedition, Sun Quan personally conquered Hefei, and Lu Xun attacked Xiangyang. But Sun Quan failed to conquer Hefei, Cao Rong personally aided, so he could only retreat, and Zhuge Liang did not break through Sima Yi's defense until his death, and died of illness in Wuzhangyuan.

Therefore, it is irresponsible to say that Sun Wu did not cooperate with the Northern Expedition of Shu and disregarded history.

Sun Quan did not have no cooperation, but he did not have the strength to cooperate. And as long as the Wushu Alliance, even if Sun Quan does not send troops, it will be a great threat to the Wei State, and the Wei State will not dare to devote the whole country to encircle and suppress Zhuge Liang.

Sun Quan continued to harbor in Jiangdong, trying to wait for Zhuge Liang and Wei to be defeated and reap the benefits of the fisherman, so he did not cooperate with Shu Han later, but later he was defeated in Hefei.

When Zhuge Liang was carrying out the Northern Expedition, Sun Quan was vigorously developing the economy of Eastern Wu, in order to preserve his strength, so he did not cooperate with Shu Han.
