Zhou Yu led an army to meet Liu Bei at Fankou. The two armies went against the current to Chibi and met Cao Jun who was crossing the river. At that time, Cao Jun had been affected by the plague, but it was difficult for the new water army to run in with the newly attached Jingzhou water army, and the morale was obviously insufficient, so Zhou Yu's water army defeated him in the first battle. Cao Cao had to "lead the water army to the north of the Yangtze River" to meet the army, lean the warships to the Wulin side on the north shore, practice the water army, and wait for the opportunity. Zhou Yu docked the warship at Chibi on the south bank, facing Cao Jun across the river. At that time, Cao Cao was not used to the northern foot soldiers taking a boat, so he connected the boat end to end, and both men and women were on board. Zhou Yu suggested to Huang Gai: "Today, being outnumbered, it is difficult to last. However, the military ship is connected with the ship end to end, and it can burn away. " On the day of the war, Huang Gai had prepared ten light boats, full of firewood and oil, disguised as red curtains and flags. At that time, the southeast wind was urgent, and there were ten ships sailing in front of Zhongjiang. Huang Gai raised the torch and made all the soldiers shout in unison: "What's going on!" " Cao Jun's officers and men were unprepared. "They all waited, watched and pointed at the words." . Two miles from Cao Jun, Huang Gai ordered the firewood to be lit, and at the same time he became very angry. The fire was fierce, and the ship flew like an arrow, burning up the north ship and extending to the camp on the shore. Smoke billowed in an instant, and countless people were burned and drowned. On the other hand, Sun Liujun crossed the Yangtze River and defeated Cao Jun in the chaos. Seeing that the defeat was irreversible, Cao Cao immediately set himself on fire and led his troops to retreat in the direction of Jiangling along Huarong Road (now Jianli North, Hubei Province). Zhou Yu and Liu Bei's troops went hand in hand, always following. Cao Jun suffered more than half of the casualties in this battle. After Cao Cao returned to Jiangling, he was afraid of losing Chibi and making the regime in the rear unstable. He immediately returned to the north, leaving Coss and Huang Xu in Nanjun (the place where Jiangling was ruled), and then appointed Lejin to guard Xiangyang, and Man Chong as Wei Fen's agent, stationed in Dangyang. Sun and Liu joined forces to win the victory in Battle of Red Cliffs. Battle of Red Cliffs's failure made Cao Cao lose the possibility of unifying the whole country in a short time, while Sun and Liu took this opportunity to develop their respective forces, and the battle between Cao Cao, Liu and Sun for Jingzhou began. After that, Cao Cao returned to the north, and there was no chance to go south on such a large scale, but he still occupied Nanyang and Nanjun (Xiangyang County and Nanxiang County were separated from Nanjun and Nanyang County [Zhang Ling County]). Liu Bei began to attack Lingling, Wuling, Guiyang and Changsha counties south of the Yangtze River, and Sun Quan ordered Zhou Yu to besiege Jiangling County of the Southern Army.
