Because, during the Three Kingdoms period, there were seven counties in Jingzhou, as everyone said. The northernmost county is Nanyang County, which is the highest among the seven counties in Jingzhou and has the most developed population and economy. ?
The seat of Nanyang County is Xiangyang, a very famous ancient city in history. It is not only the economic, military and administrative center of Jingzhou, but also the most populous city in Jingzhou.
During Liu Biao's reign in Jingzhou, there were more than 100,000 troops stationed in Xiangyang alone, accounting for two-thirds of all the troops in Jingzhou. In a sense, if a person can occupy Xiangyang, it is equivalent to ruling half of Jingzhou. ?
The second most important county in Jingzhou is Nanjun, which is now Jingzhou, Jingmen and Yichang. Its population and economic scale are second only to Nanyang County.
At the same time, the southern county named Jiangling is the most important military town in Jingzhou, because it controls the Yangtze River waterway in the whole Jingzhou area. At that time, the south was dominated by the water army, and whoever could occupy Jiangling was equivalent to controlling the initiative of the war.
In this sense, during the Three Kingdoms period, if a person can occupy Xiangyang and Jiangling, it is basically equivalent to controlling the whole Jingzhou, because with the manpower, material resources, financial resources and geographical location of other regions, even if they resist, they can't see any way out. ?
Before Battle of Red Cliffs, due to Liu Cong's surrender without a fight, Cao Cao easily occupied Nanyang County and Xiangyang Tiecheng. Of course, because Cao Cao only occupied Xiangyang City, although Liu Cong had ordered all the military and political chiefs in Jingzhou to surrender, many people simply ignored it.
For example, Wen Pin, who was guarding the north of Beijing, and Han Xuan and Huang Zhong, who were both in Changsha, did not implement them. Even Liu Bei, who had stayed in Nanyang County, took the opportunity to take away 100,000 people and planned to retreat to Jiangling to build a strategic defense line against Cao Cao.
However, Cao Cao also knew the importance of Jiangling City, so as soon as he entered Xiangyang City, he sent five thousand butchers to pursue Liu Bei, and finally succeeded in catching up with Liu Bei in Dangyang, crushing Liu Bei's goal of building a defense line in Jiangling. Then, Cao Cao led an army into Jiangling City.
From then on, it seems a foregone conclusion that Cao Cao swept Jingzhou. In this context, a large-scale wave of surrender began to appear in Jingzhou. The most representative event was Wen Pin's voluntary surrender to Cao Cao. Soon, Changsha magistrate Han Xuan surrendered voluntarily. With Han Xuan, there are two very famous figures, one is Huang Zhong and the other is Wei Yan.
In addition, several people surrendered at that time and later became famous. They are all reported in the history of the Three Kingdoms. They are HeQIA, Pei Qian and Shi Tao. Under this large-scale wave of surrender, the flag of Cao Cao was hoisted in Changsha County, Wuling County, Guiyang County and Lingling County among the seven counties in Jingzhou. As a result, only Jiangxia County guarded by Liu Qi continued to resist.
Subsequently, Cao Cao led an army into Jiangxia, and the famous Battle of Red Cliffs broke out in history. As for the process and ending, it goes without saying. After the defeat, Cao Cao withdrew from Jiangxia County, but still occupied Nanjun and Nanyang County. Of course, Xiangyang and Jiangling are also under his control. Sun Quan took the opportunity to control Jiangxia County, and Liu Bei took the opportunity to capture Changsha, Wuling, Guiyang and Lingling counties.
At that time, Changsha County was the third largest county in Jingzhou, and its jurisdiction was now Changsha City.
Changsha county in the Three Kingdoms period was obviously far behind Changsha now. Compared with Wuling County, Guiyang County and Lingling County, it has great advantages in population and economy, but it is far from Nanyang County and Nanjun County. Therefore, Changsha's position is often embarrassing, saying that it can resist, seemingly it can resist, but it really resists, and there is no way out.
Because of this, Liu Bei met some resistance when he attacked Changsha, but the problem is that it is obviously impossible to confront Liu Bei for a long time with the overall strength of Changsha County.
Because Liu Bei's overall strength is far greater than Changsha County, and Liu Bei is the banner of Jingzhou hawks. With the defeat of Cao Cao and Battle of Red Cliffs, most of the capitulators in Jingzhou followed Cao Cao and retreated northward, leaving the hawks as the mainstay. In this context, Changsha county wants to compete with Liu Bei, and I am afraid it is difficult to unify internal opinions.
Therefore, after a period of resistance, Changsha County surrendered directly when it saw something was wrong. As for Wuling, Guiyang and Lingling counties, they are governed by Changde, Chenzhou and Yongzhou in Hunan.
Even now, these three cities are not economically developed areas. During the Three Kingdoms period, they were poorer in population and economy, so it was naturally more difficult to compete with Liu Bei. So when Liu Bei's army arrived, the military and political chiefs of these three counties basically surrendered without any resistance.
While Liu Bei captured these four counties, Sun Quan was not idle. He asked Zhou Yu to lead the main force of Dongwu to fully besiege Jiangling City. After a year of hard struggle, Cao Ren, commander-in-chief of Jiangling, finally chose to give up Jiangling and retreat to Xiangyang City, while Zhou Yu took advantage of the situation to occupy the southern counties.
Since then, the seven counties in Jingzhou have been divided into three parts, with Cao Cao occupying Nanyang County, Sun Quan occupying Nanjun County and Jiangxia County, and Liu Bei occupying Changsha, Wuling, Guiyang and Lingling Counties. In terms of territory, Liu Bei occupied the greatest advantage; But in terms of strategic value, it is obvious that Cao Cao has the greatest advantage. Later, in order to resist Cao Cao, Sun Quan lent Nanjun to Liu Bei. After that, Liu Bei occupied Jingzhou.
