Go and see the general knowledge of governance for yourself.

The Battle of Chibi in the thirteenth year of Jian'an in the Eastern Han Dynasty (208) had actually established the foundation for the establishment of the Three Kingdoms, and since then, the three kingdoms of Wu, Shu and Wei have developed separately, and in the process they have all encountered extremely unfavorable periods and the most dangerous years for themselves: Cao Wei 219, Shu Han 222, which year is Eastern Wu? Let's take a look at them one by one.

Cao Wei 219.

After the Battle of Chibi, Jingzhou was divided into three, of which Cao Cao occupied the northern part of Jingzhou, including Xiangyang, Fancheng, Jiangxia County Jiangbei and Nanyang County, Xiangyang, Nanxiang, Nanyang and Jiangxia four counties are Cao Cao's southern line Jingxiang theater, the focus is on Guan Yu, Cao Cao set up a general to conquer the south to lead the Jingxiang war.

In 215, Hanzhong Zhang Lu surrendered to Cao Cao, Liu Bei was unable to sleep for it, and in 217, the Battle of Hanzhong broke out, and after nearly two years of hard fighting, Liu Bei took Hanzhong in May 219, Meng Da and Liu Feng took the three eastern counties in June, and Guan Yu launched the Battle of Xiangfan in Jingzhou in July.

The situation in 219 was very unfavorable for Cao Cao, and it can even be said that it was the most dangerous period of Cao Cao's life: on the one hand, Cao Cao was defeated and retreated to Hanzhong, because Yu Xun wanted to rebuild the defense line on the western front, so Cao Cao did not return to the court in time, but rested in Chang'an for a few months, and did not return to Luoyang with his army until October.

On the other hand, because the battle of Hanzhong was fought for nearly two years, Cao Cao's main force was deeply trapped in it and could not extricate himself, the troops in the hands of Cao Ren, the general of Zhengnan, were seriously insufficient, Guan Yu went north to besiege Xiangfan, Cao Ren was trapped in Fancheng and only a few thousand soldiers and horses in his hands, and the left general Yu Ban who came to support was flooded by Guan Yu and the Seventh Army, including Yu Ban and Pang De, 30,000 soldiers and horses were taken prisoner, Jingzhou Thorn Shi Hu Xiu, Nanxiang Taishou Fu Fang all surrendered Guan Yu, and Liang Jia and Lu Hun bandits south of Xu Du took advantage of the situation. From Xiangfan to Nanyang to Xudu, this line is under the threat of Guan Yu's soldiers.

At this time, Shu Han, the first generation of the five tiger generals only left Zhao Yun alone, Liu Bei was ready to focus on the training of Feng Xi, Zhang Nan, Fu Wei and others died in battle, Huang Quan surrendered to Cao Pi, the generals of the Mesozoic Era lost more than half, and the soldiers and horses were almost wiped out, plus Huang Zhen learned that the soldiers and horses Liu Lu blindly took away lost at least tens of thousands of elites, and the reason why Shu Han withered during the Zhuge Liang and Liu Chan periods was because the losses in the Battle of Yiling were too great.
