Main deeds:
Guard Jingzhou
In the 13th year of Jian 'an (208), Liu Bei took refuge in Liu Biao and stationed in Xinye. Cao Cao led a great army south, and Liu Beinan fled, and sent Guan Yu to meet him in Jiangling (now Jingzhou, Hubei) by hundreds of ships.
However, Liu Bei was chased by Cao Cao Jun on his way to Changbanpo in Dangyang (now Yichang, Hubei). Fortunately, Guan Yu took a boat to Hanjin (now Jingmen, Hubei) and took a boat to Xiakou (now Wuhan, Hubei).
When Liu Bei obtained the four counties of Jingnan (Changsha, Lingling, Wuling and Guiyang), he worshipped Guan Yu as the founding father and was appointed as the magistrate and general of Xiangyang. At this time, Xiangyang was actually Cao Cao's sphere of influence and was stationed by Lejin, so Guan Yu was stationed in Jiangbei. During this period, Guan Yu rebuilt Jiangling City. In the 18th year of Jian 'an (2 13), Liu Bei went to Shu to help Liu Zhang defend Zhang Lu, while Zhang Fei, Zhao Yun, Zhuge Liang and Guan Yu defended Jingzhou.
Beat Maicheng
At the end of the 24th year of Jian 'an (2 19), Cao Cao thought that Emperor Xian of Han was in Xu, close to Guan Yu's army, and wanted to move the capital to avoid its sharp edge. Sima Yi and Jiang Ji dissuaded him, thinking that Sun Quan would not want to see Guan Yu succeed, and he could send troops to attack Guan Yu from behind on the condition that he promised to seal Jiangnan to Sun Quan. At the same time, Cao Cao sent Huang Xu, Zhao Yan and other troops to rescue Fancheng, and was more prepared to conquer Guan Yu himself.
At first, Sun Quan sent someone to ask his son to propose to Guan Yu's daughter. Guan Yu insulted him and refused to get married. Sun Quan was very angry. Sun Quan ordered Monroe to sneak attack Jingzhou as a coach and personally led the army as a backup. Mi Fang (Liu Bei's brother-in-law) and the commander-in-chief of Jiangling, an important town in Jingzhou, had a deep grudge with Guan Yu and gave up without a fight.
Guan Yu led the troops to fight, and Mi Fang and the stone man were in charge of supplies, but they were unwilling to rescue Guan Yu with all their strength. Guan Yu said, "I must punish them when I go back." Mi and Shi are both afraid and uneasy. So Sun Quan secretly sent someone to seduce Mi Zhu and Shi.
At this point, Guan Yu learned that the Confederate army had fallen and immediately retreated to the south. On the way back to the military adviser, Guan Yu sent messengers to contact Lu Meng many times. Lv Meng always treated Guan Yu's emissary well, allowed various tours in the city, and sympathized with Guan Yu's relatives. Someone personally wrote a trust and asked him to take it away as a proof of peace.
When the messenger came back, Guan Yu's men asked him privately about his family, knowing that it was safe and the treatment was better than before. So Guan Yu's soldiers had no intention of fighting again, and the foot soldiers gradually dispersed and retreated to Maicheng.
In December of the same year, Guan Yu led dozens of riders to flee, all the way to Linzhou (now Nanzhang County, Xiangfan City, Hubei Province), which is only one or two miles away from Yizhou. When Pan Zhang ambushed Ma Zhong, he was captured, and his eldest son Guan Ping was killed in Linzhou.
Extended data:
After Battle of Red Cliffs, Liu Bei helped Zhou Yu of Wu Dong attack Coss of the Southern Army, so he didn't send Guan Yu to the North Road to stop Cao Cao's reinforcements. After Coss retreated, Guan Yu was appointed as the prefect of Xiangyang by Liu Bei. Liu Beijin Yizhou, Guan Yu stayed in Jingzhou.
In the twenty-fourth year of Jian 'an, Guan Yu surrounded Xiangfan, and Cao Cao sent reinforcements. Guan Yu captured Yu Jin alive and killed Pound, which greatly shocked China. Cao Cao wants to move the capital to avoid its sharpness. Later, Cao Cao sent Huang Xu to reinforce, and Monroe of Soochow attacked Jingzhou. Guan Yu was beaten between Scylla and Charybdis, captured by Pan Zhang and killed in Linzhou.
After Guan Yu's death, he was gradually deified by people and was honored as "Guan Gong", also known as bearded Gong. There have been many awards and titles in all previous dynasties. In Qing Dynasty, it was regarded as "loyal to SHEN WOO, brave to show great sage" and "warrior sage", just like Confucius "Wen Sheng". The Romance of the Three Kingdoms honored him as the leader of the "Five Tiger Generals" in Shu, and Mao Zonggang called him the "righteous person" of the "Three Wonders of Romance".
