In July of the first year of Zhangwu (22 1), that is, three months after Liu Bei proclaimed himself emperor, in order to avenge Guan Yu, Liu sent troops to attack Sun Quan of Soochow, which was a huge event. After Sun Quan failed to make peace, he decided to face Cao Wei directly and avoid fighting on two fronts. At the same time, Lu Xun was appointed commander-in-chief to command the army. After seven or eight months of stalemate between Lu Xun and Liu Bei, the army of Shu Han was finally defeated in Yiling area. After Guan Yu lost Jingzhou, the battle of Yiling was another great loss for Shu Han.

Historical background
In 2 19 AD, Sun Quan captured Jingzhou, captured and killed Guan Yu, and Wu and Shu became enemies. In 220 AD, Cao Pi proclaimed himself emperor on behalf of Han Dynasty. 22 1 year, Liu Bei proclaimed himself emperor in Yizhou, with the title of Zhangwu. In the same year, in order to recapture Jingzhou and avenge Guan Yu, Liu Bei led an army to attack Soochow.
Sun Quan heard that Liu Bei was going to cut in the future and sent messengers to make peace. Zhu Gejin, the satrap of Wu Nanjun, wrote to the North: "Your Majesty is a relative of Guan Yu, how can he be the first emperor?" Jingzhou size, familiarity and domestic? Everyone should be the enemy, who should take priority? If you review this number, it's easy to flip your hands. "
The discussion from Wu people can only arouse Liu Bei's greater resentment, but it will not have any effect. Zhang Fei, a famous Shu-Han star, led 10,000 troops from Langzhong to join forces with Liu Bei in Jiangzhou. Before he left, he was killed by his subordinates Zhang Da and Fan Qiang.
