Jingzhou originally set up seven counties, and at the end of the Han Dynasty, Xiangyang County and Zhangwu County were added, and all Jingzhou had the title of "Nine Counties of Hanshang". Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Bounded by the Yangtze River, Jingzhou is divided into Jingbei and Jingnan regions, which have always been under the jurisdiction of four counties: Wuling, Changsha, Lingling and Guiyang.

After the Battle of Chibi, Liu Bei sent Guan Yu, Zhang Fei and Zhao Yun to conquer Jingnan and captured the four counties of Jingnan, among which Guan Yu and Huang Zhong fought in Changsha, and Zhao Yun rejected the story of Guiyang County has always been talked about.

In the later period of the Three Kingdoms, Wu Guopin changed the large county to a small county, not only from Lingling and Guiyang County to separate Shi'an County, Linhe County and Shixing County, in Jingnan, but also added Wuchang County, Tianmen County, Hengyang County, Zhaoling County, Ancheng County and Xiangdong County, plus the original Wuling, Changsha, Lingling and Guiyang, the entire South Jingzhou, there are thirteen counties, the number is large, far beyond the previous generation,

As a result of the division and division of the county, which was originally very large, the original huge area of Guiyang County was also divided into extremely small counties, and there are now only six counties left in the more than 20 counties under its jurisdiction. However, as the gateway to Jingnan, the status of Guiyang County has not changed much, Guiyang County is located at the intersection of the Nanling Mountains and the Luoxiao Mountains, looking at the beauty of Hengyue in the north, and the Chong of Wuling in the south, which is the throat of Jingzhou from the north of Jiaozhou, and Shen Ying was sent to lead troops to garrison Guiyang in order to prevent the Han army from entering Jing.

The loss of Jiaoguang is already irretrievable, with the current strength of Wu, Zhou believes that the possibility of sending troops south to recapture Jiaoguang Erzhou at this moment is zero, if the southern expedition is forced, it will inevitably lead to the emptiness of the northern road, so that Chen's Han army in Jiangbei has an opportunity.

Therefore, Zhou Zhi could only retreat to the second, give up the idea of recovering Jiaoguang, increase troops in Guiyang County, hold the southern gate of Jingzhou, and prevent Liu Yin from going north.

Jiaoguang has already been lost, if Jingnan is lost again, the blow to Wu will undoubtedly be worse, the importance of Jingnan to Wu is far more important than Jiaoguang, if Jingnan is lost, Wu will lose its strategic depth in Jingzhou, and the Han army will attack Wu's Yangtze River defense line from the north and south, and the consequences will be catastrophic.

Liu Yin's strategic offensive in a big detour and depth made all the Wu people, including Zhou, unexpected, Jiaozhou is far away in the extreme south, if you send troops from the Central Plains to Jiaozhou, the long logistics supply line is a deep headache, and Zhou does not know how Liu Yin solved this problem, but Liu Yin has always been famous for winning by surprise, and this time is obviously no exception.

The task resting on Shen Ying's shoulders is really not light, but the current troops around him are overstretched, and the 30,000 horses and horses assigned to Shen Ying are already an limit of what he can mobilize.

According to the information transmitted from Jiaoguang, the Han army's invasion army this time was also 30,000 people, but these 30,000 people were not ordinary 30,000 people, but 30,000 elite cavalry, so the Han army was able to break through from the Central Plains to Jiaoguang in just two or three months.

And judging from the Han army's 30,000 elite cavalry unharmed and captured Jiaoguang, the combat effectiveness of the Han cavalry has reached a very terrible point, and the 30,000 people brought by Shen Ying are comparable to the Han army in number, but Shen Ying does not think that the combat effectiveness of his army can be compared with the Han army.

Dealing with cavalry, theoretically, the city is the most effective, but from the performance of the Han army in Jiaoguang, it has been known to the world that no matter how strong the city is, it cannot stop the sharp firearms of the Han army.

When Shen Ying was in Xiling, he had already sworn to Zhou that he wanted to live and die with Guiyang, but after he arrived in Guiyang, he had already felt great pressure, not good in the field, and even worse in defending, if Shen Ying couldn't come up with a set of effective defensive means, it is estimated that there would only be co-death left with Guiyang.

After careful consideration, Shen Ying decided to move the defense line to the south, to the front line of Mangshan, and no longer defend Chenxian.

Mangshan is a mountain range in the south of Chenxian County, named after its forest sea recklessness, python infested, here the forest and Jing are connected, the mountains and rivers are connected, the rock valley is deeply obstructed, the danger is natural, it is the only way to pass through to enter the Jing, Shen Ying led the troops to enter Mangshan, in the devil's village of Mangshan, the fierce pit stone, the cliff stone and other dangerous places set up several camps, cut off the north-south road, and prepare to fight to the death with the Han army in Mangshan.

After Liu Yin and Fu Zhao joined the division, they went north from the Qujiang River and approached Mangshan.

The steepness of the Nanling road made the speed of the Han cavalry slow down, and the scouts quickly found out the information on the Guiyang side and reported it to Liu Yin.

After Liu Yin got the letter, he sighed lightly, it seems that this Shen Ying is indeed not an ordinary person, knowing that field battles and defending the city are not the opponents of the Han army, so it is also smart to use the dangerous terrain of Mangshan to defend. However, in addition to the strength of the cavalry, the greater advantage of the Han army lies in the mountain warfare, although the tiger cavalry has been focusing on the cavalry over the years, but the tradition of the Shu army has not been left behind, riding on the war horse, they are invincible and invincible iron cavalry division, jumping off the war horse, they are still the mountain elite of the dragon and the tiger, since Shen Ying wants to fight with the Han army in the mountains, it is completely in the heart of Liu Yin.

In fact, this is also Shen Ying's helplessness, the strength of the Wu army is only water warfare, whether it is cavalry warfare and mountain warfare, it is a weakness, but now Guiyang has no big rivers, the only one Chenjiang River, or around the mountain, and later the famous lyricist Qin Guan in the Song Dynasty once left a well-known sentence: "Chenjiang is fortunate to go around Chenshan, for whom does it flow to Xiaoxiang?" ”

Without the conditions of water warfare, the strengths of the Wu army naturally could not be brought into play, in the case of field warfare, city warfare and mountain warfare, Shen Ying still reluctantly chose mountain warfare, in his opinion, this is also the only combat method that the Wu army can compete with the Han army, after all, there is a dangerous mountain as a barrier, blocking the attack of the Han army There is still a great hope. If it was a field battle or a city defense battle with the Han army in Chenxian, the Wu army would have no chance of winning.

After the Han army soldiers came to Mang Mountain, the first key pass to be conquered was the devil's village, the mountain road here was steep, it was no longer suitable for the cavalry to ride on horseback, Liu Yin ordered Luo Shang to lead 5,000 people as the vanguard, abandon the horse on foot, climb the rock and advance.

No matter how steep and rugged the mountain road is, it is difficult to defeat the Han army, and the 5,000 people led by Luo Shang are not formed troops, but selected from 30,000 people, most of them are the troops of the original Shu region, plus some elite people who are strong and good at climbing, so that they can be the vanguard of the way, and launched an attack on the devil's village that the Wu army is discerning.
