In the eighteenth year of Jian'an (213), after Cao Cao won the Battle of Weinan, he turned his attention to the south again, and Sun Quan was also actively preparing to resist Cao Cao's attack.

The two sides finally started a big battle at the mouth of the water, although Cao Cao achieved certain results, but did not cause substantial damage to the Sun Quan group, this battle Cao Cao finally looked at the river and sighed, had to retreat.

【Relocation of Moling, Building Mustache】

In the sixteenth year of Jian'an (211), Zhang thought that the mountains and rivers of Moling were majestic and the terrain was dangerous, and persuaded Sun Quan to take Moling as a place of governance. In the past, when Liu Bei passed through Moling to the east, he also persuaded Sun Quan to live there. Sun Quan then built a stone city, moved the governance office to Moling, and later renamed Moling as Jianye.

According to the "Jiangbiao Biography", Hong Weiquan said: "Moling, placed by King Wu of Chu, is called Jinling. The topography of Gangfu even stone, visit the old man, the first emperor of the Qin Dynasty in the past will pass through this county, the terrain of Yunjinling has the gas of the king's capital, so dig off the gang, change the name of Moling. Where this place exists, the earth has its breath, and the heavens ordained it, it should be the capital. "The right is good at discussing, but I can't follow it. After Liu Beizhidong, he stayed in Moling, looked at the terrain around, and also persuaded the power of the capital. Quan said: "The wise man agrees." "So it's all right.

"Offering the Emperor Spring and Autumn" Yiyun: Liu Bei went to Beijing, and Sun Quan said: "Wu went here for hundreds of miles, that is, there was an emergency, and it was difficult to go to the rescue, and the general had no intention of tunjing?" Quan said: "There are more than 100 miles of small rivers in Moling, and you can install big boats. Bei said: "Wuhu is close to the beard, and it is also good." Quan said: "I want to go to Xuzhou, I should go closer." ”

Moling, or Jianye, is actually the future Nanjing, Sun Wu is also the first kingdom in Chinese history to finally set the capital here, Sun Quan called the emperor is in the first year of Huanglong (229) officially issued an edict to move the capital Jianye.

Since then, the city of Nanjing has gradually become the political and economic center of southern China.

Later, Sun Quan heard that Cao Cao planned to go east again, so he built a dock to prevent Cao Cao from invading the south.

According to the "Wu Lu" record, at that time, Sun Quan was preparing to build a camp on both sides of the mouth of the water, and the generals said: "Go ashore to attack the enemy, wash your feet and get on the boat, what is the use of camping?" Lu Meng said: "There are times when the military is going well, and there are times when there are defeats, and we will not win every battle, if the enemy suddenly appears, and the infantry cavalry is pressing, we can't even reach the water's edge, can we get on the boat?" Sun Quan said, "That's right! So he ordered the construction of a camp, which was called the Whisker Dock.

【Migrating People】

After the Battle of Red Cliffs, Cao Cao was quite jealous of Sun Quan, so in order to prevent Sun Quan, he planned to move the people of Huainan to the west of the Yangtze River, although this matter was advised by Jiang Ji, but Cao Cao did not change his mind, but the result was not as Cao Cao expected.

In the fourteenth year of Jian'an (209), Jiang Ji sent an envoy to meet Cao Cao in Qian County, and Cao Cao planned to move the people of Huainan inward in order to prevent Sun Quan's attack, so he asked Jiang Ji: "In the past, I confronted Yuan Shao in Guandu, and the people of Yan and Baima migrated to each other, but none of them fled, and the enemy army did not dare to plunder. Now, I want to migrate the people of Huainan, what do you think? ”

Jiang Ji disagreed with the migrants, saying: "At that time, I was weak and strong, and if I didn't move, I would lose." Since defeating Yuan Shao, reaching Liucheng in the north, and surrendering to Jiang, Han, and Jingzhou in the south, the people have no other ambitions. But the people are nostalgic for the old land, and are not happy to move, and if they hear about it, they will be afraid and uneasy. ”

Cao Cao did not listen, but still decided to forcibly relocate the people of Jianghuai, and as a result, more than 100,000 people in Jianghuai fled to the territory of Eastern Wu because they were frightened. Cao Cao admired Jiang Ji's talents because of his views on the migrants, and when Jiang Ji was later sent to Yecheng by his envoys, Cao Cao laughed and laughed at himself when he saw Jiang Ji: "I wanted to let the people take refuge, but I drove them all away." So he worshiped Jiang Ji as the Taishou of Danyang, and then Cao Cao took Wen Hui as the assassin of Yangzhou, and appointed Jiang Ji Yangzhou again, and ordered: "Although the virtuous Ji Zi would rather give up the position of the monarch and be willing to be a minister, Wu must always have a monarch to be responsible for governance." Now that you are governing Yangzhou again, what am I not worried about? ”

It is said that after Cao Cao decided to relocate the people, the people of Jianghuai told each other, frightened, from Lujiang, Jiujiang, Qichun to Guangling, more than 100,000 households all crossed the Yangtze River eastward. The west of the Yangtze River is deserted, and in the south of Hefei, there are almost only the people of Anhui City.

【Battle of Misuguchi】

After Cao Cao's victory in the Battle of Weinan and the pacification of Guanzhong, the remnants of the remaining princes of Liangzhou were not worried, so he turned his attention to the south again, and at that time, there was no doubt that Sun Quan was Cao Cao's greatest opponent.

In the first month of the eighteenth year of Jian'an (213), Cao Cao personally led a large army to attack the Wuxuwu, broke through Sun Quan's camp in Jiangbei, and captured his general Sun Yang, who held on to him for more than a month, and asked Liu Bei for help.

At that time, Gan Ning was the front governor of the Wu army, and was ordered to attack the enemy's front camp, and Sun Quan gave him rice wine and many dishes, and Gan Ning distributed these wines and dishes to more than 100 of his subordinates. After eating, Gan Ning first poured wine in a silver wine bowl, drank two bowls of himself, and then poured wine and handed it to his governor, who bowed down and refused to take the wine immediately. Gan Ning picked up a bright knife and put it on his lap, and rebuked Du Du and said, "What do you compare to Gan Ning when you are known by the Lord? I'm not afraid of death, why are you afraid of death? Seeing Gan Ning's stern voice, the governor immediately got up to thank him and accept the wine, and all the soldiers also poured a bowl. By the time of the second watch, the crowd slashed and slashed the enemy with a piece of ammunition in their mouths, causing the enemy camp to shake in fear.

After that, Cao Cao took the lead in retreating. The battle ended with Sun Quan's victory.

According to the "Jiangbiao Biography", Cao Cao sent troops to wet his beard, claiming that there were 400,000 infantry and cavalry, and he drank horses near the river. Sun Quan led 70,000 troops against him, and made Gan Ning lead 3,000 men as the vanguard governor. Sun Quan secretly ordered Ning to enter Cao Wei's army at night. Gan Ning then selected more than 100 strong men under his command, went directly to Cao Cao's military camp, pulled out the antlers, crossed the base into the camp, and beheaded dozens of them. The northern army shouted in horror, holding torches like stars, but Gan Ning had already returned to the barracks, preaching and cheering loudly.

Sun Quan met Gan Ning at night and said happily: "Do you think this can frighten me?" It's just to see how brave you are." So he gave Gan Ning a thousand silk horses and a hundred knives. Sun Quan said: "Cao Cao has Zhang Liao, and I have Gan Xingba, which is comparable to him." Cao Cao's army stopped here for more than a month and then retreated.

According to the "Wu Calendar", Cao Cao sent troops to wet his beard at that time, used it as an oil tanker, and crossed the island at night. Sun Quan led the navy to surround and capture more than 3,000 Cao Cao's soldiers, and several thousand other drowning people. Hou Sun Quan challenged many times, but Cao Cao couldn't stick to it. Sun Quan then came in person and took a light boat to break into the front line of Cao's army from Baxukou to observe the deployment of Cao's army. The generals of Cao's army thought that Sun Quan was here to provoke and wanted to beat him, but Cao Cao said: "Sun Quan must have come here to see how my army is doing", so he ordered the army to be under martial law, and bows and arrows could not be fired casually. Sun Quan's light boat traveled five or six miles, and Cao Cao saw that Sun Jun was rectifying and mighty, and sighed: "Giving birth to a son should be like Sun Zhongmou, and Liu Jingsheng's son is like a pig and a dog!" ”

Sun Quan wrote to Cao Cao, saying: "The spring water is about to rise, you should withdraw your troops as soon as possible." A separate piece of paper reads, "If you don't die, I won't be at peace." Cao Cao said to his generals, "Sun Quan doesn't deceive me." So they withdrew and returned to the north.

According to the "Wei Luo", once Sun Quan came to Cao Cao's army on a large boat to observe, and Cao Cao ordered bows and crossbows to shoot Wu boats. After a while, Sun Quan's light boat was in danger of capsizing because there were too many arrows on one side, and the hull was tilted. Sun Quan ordered the bow of the ship to be turned so that the other side could receive another arrow. After a while, the arrows were even, and Sun Jun's drums sounded in unison, and he returned safely.

【Draw】

In the thirteenth year of Jian'an (208), Sun Quan went north to attack Hefei and failed. Five years later, in the eighteenth year of Jian'an, Cao Cao went south to seize the mouth of the Xukou without success, and the two major groups of Cao Wei and Dongwu basically fought a draw on the line from the lower reaches of the Yangtze River to the Huai River.

This also reflects the advantages and disadvantages of the two groups at that time, the Cao Wei group was in the north and was good at land warfare, while the Sun Quan group was in the south and was good at water warfare, so it was difficult for Sun Quan to conquer Hefei, which was the focus of Cao's army, on land, and Cao Cao could not cross the Yangtze River to lay down the beard.

The interruption of these two battles was only a preliminary test between the two sides, and the confrontation between Cao Wei and Sun Wu had just begun.
