When Guan Yu was defeated, if Liu Feng and Meng Da went to the rescue, would it be time? It is generally believed that Guan Yu's defeat was simply caused by himself. He was arrogant, had no one in his sight, and offended a circle of people around him. Whether it was his own people or enemies, he was finally taken out of his nest by Mi Fang and Shiren.
To answer the question above. We are going to discuss two aspects, about the route from defeat to capture and whether rescue will come in time. Guan Yu was roughly like this from defeat to capture, defeated and retreated to Nanjun, and learned that Jingzhou was lost, and continued to retreat to Nanjun. Knowing Sun Quan's personal arrival, he turned to Maicheng in the northwest. Sun Quan sent Pan Zhang and others to intercept Guan Yu and was captured in the stone.
After Guan Yu's defeat, he must immediately send people to Fang Ling to ask for help, but Liu Feng and Meng Da of Fang Ling did not send troops. What would happen if Liu Feng and Meng Da came to the rescue?
From Guan Yu's defeat to capture, he successively went from Xiangfan to Jiangling, from Jiangling to Maicheng, from Maicheng to Zhangxiang, from Zhangxiang to Jiashi, and was captured in Jiashi. Guan Yu's marching distance was about 500 li. Various factors are taken into account, such as tens of thousands of troops marching and so on. It took up to a week from Guan Yu's defeat to the capture of the stone.
And from the age of the house to the rocks, it is about 400 li. Fangling to the stone is the only way to enter the Jianghan Plain east of Qinchuan, and all the way is lofty mountains. In ancient times, good horses marched, about 190 miles a day. Various factors were taken into account, such as Liu Feng and others receiving reports of defeat, the departure of the whole army, marching and other factors. It would take at least four days from the time Guan Yu issued the news of defeat to the time Liu Feng and Meng Dajun arrived at Jiashi.
Therefore, if Liu Feng and Meng Da immediately sent troops to rescue Guan Yu after receiving Guan Yu's request for help, although the time was very tight, it was still possible to save Guan Yu. This is also the reason why Liu Beiji later hated Liu Feng.
