Ask for a speech about Battle of Red Cliffs.

During the formation of the Three Kingdoms, in the 13th year of Jian 'an of Emperor Xian of Han Dynasty (208), the joint forces of Sun Quan and Liu Bei defeated Cao Cao's army in Chibi of the Yangtze River (now northwest of Puyin, Hubei, northeast of Jiayu), which laid the foundation of the Three Kingdoms.

After Cao Cao basically unified the north, he trained sailors in Xuanwu Pool and took measures against the Guanzhong area where unrest might occur. Then, in July of the 13th year of Jian 'an, in order to unify the north and south, he sent more than 100,000 troops to conquer Jingzhou (now Hubei and Hunan). At this time, Sun Quan has conquered Xiakou (now Wuhan) from Jiangdong, opened the gateway to Jingzhou in the west, annexed Jing and Yizhou (governing Chengdu) and then developed northward; Liu Bei, who was attached to Liu Biao in Jingzhou, took Zhuge Liang as his counselor and made a strategy of taking advantage of Jing and Yi, uniting with Sun Quan and marching into the Central Plains, and practiced the water army in Fancheng. Cao's weaknesses, such as hard work, acclimatization, being shorter than water war and lack of food, strengthened Sun Quan's determination to resist Cao Cao. Sun Quan, regardless of the main opposition Zhang Zhao, appointed Zhou Yu as the viceroy, Cheng Pu as the deputy viceroy, and Lu Su as the commander of the praise army. He led 30,000 elite sailors, joined forces with Liu Bei for about 50,000, and went up the river and entered Xiakou.

After Cao Cao captured Jiangling, he took Wen Pin, the general of Liu Biao, as the satrap of Jiangxia, and still unified his own army to guard Hanchuan (now Jianghan Plain). Liu Zhang, an animal husbandry in Yizhou, also sent troops to supplement Cao Cao's army and began to pay tribute to the court. Cao Cao is proud and underestimates his enemy. He didn't listen to Jia Xu, the counselor, and sent a letter to intimidate Sun Quan, claiming to fight Wu. In winter, the pro-unification army goes hand in hand along the Yangtze River.

Sun and Liu joined forces behind the gorge, and then they went back to the river to meet Cao Jun and meet at Chibi. Cao Jun last stand, who lost his prestige, was readmitted and returned to Jingzhou. His fighting capacity was poor and all diseases prevailed, so that he lost the first battle. He hurriedly retreated to the north shore, stationed in Wulin (now Honghu, Hubei) and confronted the allies across the river.

Cao Cao ordered the warships to be connected, which reduced the turbulence and facilitated the boarding of northern soldiers. They want to step up their training and attack by standing by. In view of the long-term disadvantage of being outnumbered, Zhou Yu is determined to find a chance to make a quick decision. According to the weakness of Cao Jun's "serial ship", Huang Gai suggested fire attack, which was well received. Huang Gai immediately sent someone to send Cao Cao a fake surrender letter, and then set off with dozens of ships. The front 10 boat is full of dry firewood soaked in oil, covered with cloth, planted with the flag agreed with Cao Cao, tied with a canoe and headed for Wulin along the southeast wind. When approaching the other side, Cao Jun, who let his guard down, rushed over and watched Huang Gai come down. At this point, Huang Gai ordered the firewood to be lit, and each boat was changed to retreat. Fireboat broke into Cao Jun's fleet in the wind, and suddenly it was ablaze, and the fire quickly spread to the shore camp. The allied forces took advantage of the situation to attack, and Cao Jun suffered heavy casualties. Knowing that the defeat was irreversible, Cao Cao ordered the burning of the remaining ships and led the army to retreat.

The allied forces inscribed on Chibi Mountain in Chibi City went hand in hand with the water and pursued Cao Jun. Cao Cao led his troops away from the riverbank, took a shortcut to Jiangling, crossed Huarong Road (now diving in the south of the Yangtze River), met with mud, rode grass and ran away. Cao Cao left Coss guarding Jiangling, while Man Chong stayed in Dangyang and returned to the north.

Zhou Yu and others confronted Coss across the river and sent Gan Ning to attack Yiling (now Yichang). Coss divided his troops around Ganning. Zhou Yu led the army to rescue and defeated Cao Jun, then crossed the north bank of Jiangtun and continued to confront Coss. After Liu Bei returned to Xiakou from Jiangling, he returned to Hanshui and went around behind Coss. Coss knew it was difficult to continue the stalemate, and he was forced to retreat the following year.

Battle of Red Cliffs and Cao Cao were conceited, underestimating their enemies, making mistakes in command, and the water army was not strong, which eventually led to defeat. Sun Quan and Liu Bei calmly analyzed the situation in the face of strong enemies, formed an alliance to resist the Japanese war, enhanced the strength of water warfare, and skillfully attacked with fire, thus creating a famous war example in China's military history.
