Cao Cao: These three brothers are dissatisfied with me every day, and they crack and scold me when they meet me, this time it's okay, let's be blown up, the dignified king of Wu asks to marry your daughter as a daughter-in-law, you are not happy, you are really arrogant.

Sima Yi: How did I hear that Guan Yu was also quite dissatisfied with Zhuge Liang.

Liu Xiu: This is really conceited, to put it bluntly, a king and a courtier, people come to ask for marriage, Guan Yu is Gao Pan, even if he disagrees, he can't insult others, the military general is reckless, and he has no IQ at all!

Zhuge Liang: Guan Yu's ability is still good, but this time he is really too conceited.

Zhou Yu: You're such a good old man.

Sima Yi: After Lu Bu's death, Guan Yu believed that he was invincible in the world, and everyone he saw was like a traitor.

"Then it is very clear that Sun Quan took advantage of Guan Yu to launch the Battle of Xiangfan and attacked Jingzhou."

Guan Yu sent troops from Jingzhou Nanjun to attack Cao Wei's Xiangyang and Fancheng, known as the "Battle of Xiangfan" in history, this battle Guan Yu flooded the Seventh Army, Megatron China, Cao Boss was beaten to want to move the capital, when the Cao army was defeated and retreated, Jiangdong rats took advantage of the weakness to enter and sneak attack Jingzhou, Guan Yu was defeated and took Maicheng, and was finally captured and killed by the Wu army, and a generation of martial saints finally ended up with the separation of corpses. ”

As a result, Liu Bei not only lost Jingzhou, but even Guan Yu, the second person in Shu Han, was also in a different place.

So, Liu Bei, who was furious, launched the Battle of Yiling. ”

"Liu Bei personally led tens of thousands of soldiers and horses to launch a large-scale war against Eastern Wu, and in the face of the fierce Liu Bei, Sun Quan sent an envoy to ask for peace, but Liu Bei refused."

At this time, Liu Bei was directly furious, how could he agree to ask for peace, you have killed my brother, and you still ask for peace? And because of this, he fell into Sun Quan's scheme and let the world of Shu Han decline directly. ”

"After knowing that peace could not be sued, Sun Quan declared himself a vassal to Cao Wei and ordered Lu Xun to bring direct troops to meet Liu Bei."

Liu Bei was angry and eager to win, the soldiers were in full swing, Lu Xun analyzed that Wu Jun should temporarily avoid the edge, there is a saying called "the time and place are favorable", Liu Bei in the anger completely forgot to look at the surrounding terrain and environment, only felt that there were many people, there must be nothing, so let the opposite side fight very badly. ”

"So, Lu Xun led the Wu army to retreat again and again, until it retreated to the line of Yidao and Yaoting, and in this way, the Wu army withdrew from the area of high mountains and mountains, leaving Liu Bei with hundreds of miles of mountains that were difficult to deploy."

"Because the Shu army is located on a rugged mountain road of two or three hundred kilometers in the Wu realm, far away from the rear, there are many difficulties in logistics support, and with Liu Bei's 100-mile company camp, the troops are scattered, which provides an opportunity for Lu Xun to carry out a strategic counterattack."

"The two sides held each other until June 222, and because Lu Xun had been holding on without a fight, the Shu army, which was pleading for a quick victory, gradually became discouraged."

"Lu Xun thought that the time had come, and began to carry out a counteroffensive, and thought of the combat method of attacking the Shu army company and camp."

"A raging fire ignited the Shu Han military camp, and the fire of Yiling led to Liu Bei's fiasco, the Shu army generals Zhang Nan, Feng Xi and the indigenous tribal leader Sha Moke were killed, and Du Lu, Liu Ning and others surrendered."

"Liu Bei saw that the general trend had gone, so he fled to Ma'anshan in the northwest of Yiling, the two poles reversed, Lu Xun ordered people to besiege on all sides, the Shu army was defeated, tens of thousands of soldiers and horses were destroyed, most of them were killed and wounded, and the military supplies were lost."

"Liu Bei took advantage of the night to break through, and Fu Wei, the general of the Shu army, led his troops to break off for Liu Bei, Fu Wei was outnumbered, and finally died in battle."

On the way to escape, Liu Bei was almost captured by Sun Huan again, and finally crossed the mountain and fled into Yong'an City. At that time, Huang Quan, the general of Zhenbei, was cut off by the Wu army after Liu Bei's defeat and retreat, and Huang Quan was ashamed to surrender to Eastern Wu, so he took refuge in Cao Wei. ”

"At the same time, Ma Liang, the most outstanding of the Ma Family's Five Constants, was also intercepted and killed by Wu General Buqi."

"I know that some people don't know the characters I'm talking about, these people are like the outstanding generals of various dynasties, and I am also expressing to the world the tragedy of the Battle of Yiling at that time."

At that time, there were at least 20 outstanding generals in Shu Han who participated in the war, and among them, seven people fought to the death, such as Fu Wei, Sha Moke, Feng Xi, Zhang Nan and others. In addition, five generals surrendered to the enemy. Among them, Huang Quan, Shi He, and Pang Lin joined Cao Wei's camp, while Du Lu and Liu Ning surrendered to Eastern Wu, and there was also a general Chen Shi with no trace and his life and death unknown. ”

"Aside from the tens of thousands of soldiers, this list alone is enough to cause Shu Han to suffer a heavy blow, and besides, after this battle, Liu Bei's life is also a fatal blow to the Shu Han regime established in the name of Liu Bei."

"For a time, Shu was worried about domestic and foreign troubles, and the Shu Han regime was crumbling."

"Then, Liu Chan succeeded to the throne, but the country's military and political power was basically in the hands of Zhuge Liang, Zhuge Liang's intentions were good, and he hoped that in his lifetime, the Northern Expedition would be successful, revive the Han Dynasty, unify the Central Plains, and end the war!"

"It is also thanks to Zhuge Liang, a prime minister in Shu State, Rao is so, Zhuge Liang also spent several years and hard work to stabilize the situation, and improve the national strength to the point where he can go out to fight abroad!"

"In 223, Liu Bei died of illness, and the White Emperor City was entrusted to Gu, and the Shu Han that was passed to Liu Chan and Zhuge Liang was a devastated stall."

"In terms of territory, Shu Han only has Yizhou left, the land is narrow and there are few people, the land of Shu, Wu and Wei is almost 7:2:1, Shu Han is not only at the bottom, it is simply miserable, Liu Bei led the troops into Sichuan, and was wiped out a lot by Lu Xun, the emperor is young, and the waves in the court are unavoidable."

"And all the hope is pressed on Zhuge Liang."

"If you want to keep Shu Han, you have to solve at least one problem, and Liu Changang has just ascended the throne and has internal worries, which is not so easy to solve."

"Zhuge Liang knows the importance of the Sun-Wu alliance, it is the foundation of the Shu Han state, so although the Eastern Wu first betrayed the covenant and conspired to seize Jingzhou, but the Cao Wei regime in the north is eyeing the tiger and has always been the biggest threat to the Shu Han, so Zhuge Liang endured the humiliation and sent important ministers to the Eastern Wu, and Sun Quan was also happy to see it, so the two sides rebuilt the Sun-Liu alliance."

"The external troubles are stable, but Zhuge Liang also knows that this is not a long-term alliance, and he must restore the strength of Shu during this period."

However, Liu Bei's battle of Yiling was a great competition of national strength, and after the defeat, the talents and elite troops of Shu were almost lost. , after Zhuge Liang took over the regime, there were no soldiers to call on. ”

"Therefore, Zhuge Liang used various policies and means to encourage the people to actively serve as soldiers, spent more than two years training soldiers, recuperating their strength, and finally recovered Nanzhong, crossed Lushui, captured Meng Shu seven times, and returned to the heart of Nanban, successfully stabilizing the rear of Shu."
