At that time, under the pressure of Cao Cao, Jiangdong was divided into the main surrender faction dominated by Zhang Zhao and the main battle faction dominated by Zhou Yu and Lu Su.

【Zhang Zhaohe's main descending faction】

In history, Zhang Zhao was originally the number two person in the Soochow Group, and he was a high-powered minister of Tuogu, but it was because of the surrender of the Lord on the eve of Chibi that his status fell sharply and was overtaken by Zhou Yu, of course, this is also a later story.

Zhang Zhao was Sun Quan's military advisor at that time, but in the treatment of Cao Cao, Zhang Zhao's approach has always made Sun Quan not very satisfied. Earlier, Cao Cao asked Sun Quan for a proton, Zhang Zhao was hesitant and indecisive in this regard, on the contrary, Zhou Yu was decisively opposed, and also persuaded Sun Quan's mother, so Sun Quan was very trusted.

After Cao Cao annexed Jingzhou, Zhang Zhao completely gave up hope and advocated surrender, and got a lot of supporters, although Sun Quan didn't say anything, but he was actually very uncomfortable.

Of course, the reason why Zhang Zhao completely fell to the surrender faction at that time was not because he wanted to change the court like Kuai Yue, Han Song and others, and was ready to hug Cao Cao's thigh, but Zhang Zhao really couldn't see hope at that time, the strength contrast between Sun Quan and Cao Cao was too great, and it was really desperate to fight Cao Cao who had great righteousness and controlled at least eight states with the land of six counties, especially when Cao Cao controlled Jingzhou, and the Yangtze River natural danger that Sun Quan's group could rely on in the end was gone, in Zhang Zhao's view, At that time, Sun Quan could not come up with anything against Cao Cao.

Moreover, after the death of Sun Ce at the beginning, Zhang Zhao did not support Sun Quan at the beginning, and later although Zhang Zhao also tried his best to assist Sun Quan, this does not mean that Zhang Zhao fully recognized Sun Quan, especially in the military, Sun Quan lost in the early years of the crusade against Chen Deng, and then went to the throne to defeat Huang Zu several times, and in the twelfth year of Jian'an (207) Cao Cao has eliminated the Yuan clan in the north, and also crusaded against the Wuheng people, but Sun Quan has not even opened the door of Jingzhou, so the strength of Sun Quan can not be compared with Cao Cao, The military level Sun Quan is also unforgettable, and now there is no natural danger of the Yangtze River, in this case, it is understandable that Zhang Zhao persuaded Sun Quan to surrender directly.

Pei Songzhi also commented on this matter in later generations: "Chen Songzhi thought that Zhang Zhao persuaded Cao Gong to exist, isn't it far away? Fu Qi Yang Xiu Zhengse, commissioned Sun's family, honest to the beginning of bad luck, charcoal at the beginning, self-policy and power, only slightly supplemented, is to be sincere Kuangbi, in order to become its industry, on the Han Dynasty, under the protection of the people; Dingzhi's plan is not his ambition. Cao Gong rose smoothly, and the merit was established with righteousness, hoping to clear all the flowers, expand the Jingying, and the opportunity of Dading was in this meeting. If the Zhao Proposal is obeyed, then the six will be one, how can there be a military calamity, and it will be the disadvantage of the Warring States! Although it is not for the Sun family, it is great in the world. The former sinus melted back to the Han Dynasty and rose and fell with the country; Zhang Lu descended to Wei, and the reward was extended to the world. The situation is full of Wu, obedient to the wind, and the thickness of the pet spirit is measurable! However, it is clear that he is plotting for others, is it disloyal and just! ”

Before the Battle of Chibi, Cao Cao's domination of the world was actually an obvious trend, which was not in doubt at the time, after taking Jingzhou, Eastern Wu was basically isolated, Yizhou Liu Zhang sent envoys to pay tribute and submit, Han Sui, Ma Chao and others lived in the west, did not see the intention of rebellion, Zhang Lu in Hanzhong basically did not pose a threat to Cao Cao, and the Gongsun of Liaodong was not the era of Haojie Gongsun Du.

After Jingzhou was obtained by Cao Cao, Zhang Zhao persuaded Sun Quan to surrender, but in fact, he was just following the general trend. It's just that Zhang Zhao didn't expect that the trend can be changed.

[Zhou Yu, Lu Su and the main battle faction]

According to the "Jiangbiao Biography", in the meeting to discuss whether to fight against Cao Cao, Sun Quan drew his saber and slashed at the recital in front of him, saying: "The generals and officials, if you dare to say that you should surrender to Cao Cao, it is the same as this recital!" ”

And that night, Zhou Yu went to see Sun Quan again and said: "Everyone only saw Cao Cao's letter saying that there were 800,000 water and 800,000 troops and they were frightened, and they no longer analyzed the truth and falsehood, so they put forward the opinion of surrendering to Cao Cao, which is too unusual." Now let's calculate the facts, the Central Plains army led by Cao Cao is only 150,000 or 60,000 people, and they have been exhausted for a long time; The newly received troops of Liu Biao, with a maximum of 70,000 or 80,000 men, were still suspicious. With a weary soldier, he harnessed the suspicious people, and although they were numerous, there was nothing to fear. As long as I have 50,000 elite soldiers, it will be enough to subdue the enemy army, I hope the general will not worry! ”

Sun Quan patted Zhou Yu on the back and said, "Zhou Gongjin, you have come to this point, which is very much in line with my heart. Zhang Zhao, Qin Song and others, each taking care of their wives and children, had selfish intentions, which disappointed me very much. Only you have the same opinion as Lu Su and me, and this is the two of you sent by God to assist me. 50,000 elite soldiers are difficult to assemble for a while, 30,000 people have been selected (one says 20,000), warships, grain and grass and weapons and equipment have been prepared, you and Lu Su, Cheng Pu led the troops first, I should continue to mobilize men and horses, transport more baggage, grain and grass, as your backup. If you can defeat Cao Jun, you can make a decision immediately; If you lose, retreat to me, and I will fight Cao Cao for victory. ”

It can be said that Zhou Yu not only put forward four reasons for defeating Cao Cao, but also actually analyzed the strength of Cao Cao's army at that time, and was a general in the main battle faction, which played a crucial role.

But we can't ignore Lu Su because of this, Cao Cao, who advised Sun Quan to confront him, and now there are only three people recorded: Lu Su, Zhou Yu and Zhuge Liang, of which Lu Su focused on Sun Quan's monarchy, Zhou Yu focused on the actual situation, and Zhuge Liang used the method of agitation, and in fact, Sun Quan did not want to surrender, so after discussing with them, he strengthened his determination to fight Cao Cao.

Among them, Lu Su played a very key role in series, at that time Zhuge Liang was brought by Lu Su from Liu Bei, and Zhou Yu was also called back by Lu Su to Sun Quan, Lu Su himself had already begun to consider the changes in the situation after Liu Biao's death, and quickly asked to send an envoy to Jingzhou to seek an alliance to fight against Cao Cao, but he didn't expect Liu Cong to be such a waste material, and before the Lu Su people arrived, they had already surrendered, and Lu Su had no choice but to further woo Liu Bei.

It can be said that without Lu Su, Zhuge Liang and Zhou Yu may not be able to see Sun Quan, and without the help of Zhou Yu and others, it is very difficult to say whether Sun Quan can persist against Cao Cao in an atmosphere of surrender.

Zhou Yu was important on the issue of Sun Quan's resistance to Cao, but Lu Su was even more critical.
