It is worth noting that Cao Cao has so many troops that there are more than 30 thousand reinforcements in his class. Why did Cao Cao only give Coss a few thousand people?
Coss fought very hard in these two battles, with too few troops, which can be said to be risky. Isn't Cao Cao afraid that Coss will be destroyed by Zhou Yu and Guan Yu? Why didn't Cao Cao give Coss more troops?
Let's look at the battle of South County. In the 14th year of Jian 'an (209), Zhou Yu led tens of thousands of troops to attack Nanjun. At that time, Zhou Yu's troops were at least 20,000 to 30,000, because Battle of Red Cliffs and Sun Quan gave Zhou Yu 30,000 troops to mobilize. There should be 30 thousand this time And Coss guarding Jiangling, only a few thousand people, not many troops.
According to the biography of the reflection of Cao Incheon, Yu attacked ten thousand people and thousands of strikers arrived. Ren Deng went to the city to look at it, but he led 300 people and led troops to meet him. Thieves have more money, so they are surrounded.
Zhou Yujun led thousands of troops, and Coss looked at the city, recruited 300 men, and told Jin Niu to meet Zhou Yujun. Soon, Jinniu was besieged, so Coss put on armor, rode out of the city with dozens of men, rushed into the enemy's encirclement, fought hard, rescued Jinniu and his men, and repelled the enemy. Coss was stunned by the three armies and was called heaven and man.
This time, Coss won by a narrow margin.
Later, Coss was besieged by Zhou Yujun and held out for a year. Cao Cao sent Li Tong and other reinforcements to save Coss, but Guan Yu's north road was blocked. Coss had a narrow escape and finally left the city. The only bright spot is that Zhou Yu was injured by this battle.
Besides, in the battle of Xiangfan, in the twenty-fourth year of Jian 'an (2 19), Guan Yu attacked Fancheng in the north, with about 20,000 to 30,000 troops, while Coss held Fancheng, with only a few thousand troops, and the disparity in strength was still great.
