Huainan has always been a strategic place in ancient China, known as the "throat of Zhongzhou, the barrier of Jiangnan". If the regime in Jiangnan could keep Huainan, it could move forward and backward freely. Eastern Wu, on the other hand, was more awkward, and Huainan was never under his control. The so-called Yangtze River natural danger is really not as invincible as Luo Guanzhong said. In order to compete for Huainan, countless conquests from Sun Quan to Sun Hao failed. However, there is one thing that everyone may not have found, Sun Quan hit Hefei in the early stage, and then after Sun Quan died, he hit Shouchun, what is the reason for this.
The importance of Huainan
Let's start by talking about how important Huainan is. In the later Period of the Southern and Northern Dynasties of the Three Kingdoms, the Southern Dynasty was able to maintain a long-term military superiority position, in addition to the long-term war in the North, the Huainan front was the key. In the later Chen Dynasty, the Huainan line was lost, and the unification of the north and south was no longer hindered from a military point of view. The only obstacle is the degree of integration of the north and south of Han culture. After the five dynasties of the Northern and Southern Dynasties, Sui and Tang Dynasties, the situation was the same. Yang Xingmi, because of his possession of Huainan, was strong and prosperous, and eventually developed into the Southern Tang Dynasty, the largest country in the south. However, Emperor Zhongzong of southern Tang lost Huainan, resulting in the weakness of the southern Tang state and the slaughter of others. Therefore, the importance of Huainan is self-evident. So, how did Eastern Wu come to attack Huainan again and again? Look at the origin of Sun 100,000 titles.
The origin of Sun 100,000
The monarchs of Eastern Wu, starting from Sun Quan, the brave martial gene was completely lost. It is estimated that Sun Jian and Sun Ce were too fierce and used up their character. Therefore, at the beginning of Sun Quan, except for Cao Cao, who saw that Wu Jun's armor was clear and the formation was neat and said, "When you have a son, you should be like Sun Zhongmou", our Zhongmou brother really did not achieve much in the military. I think Cao Cao later regretted saying such a sentence. While he was alive, Sun Quan attacked Hefei six times, spanning twenty-seven years. If there was another "Romance of the Three Kingdoms" with Eastern Wu as the protagonist at that time, it is estimated that the script of six Qishan could be given to Sun Quan.
The thirteenth year of Jian'an (208 AD) was after the victory of the Chibi Battle, in order to expand the results of the battle; the nineteenth year of Jian'an (214 AD) was the battle between Liu Bei and Cao Cao Hanzhong, the main force was on the western front; the twenty-fourth year (219 AD) was Guan Yu attacking Xiangfan; the second year of Huanglong (230 AD) was cao Zhen leading the army to attack Hanzhong; the second year of Jiahe (233 AD) was this time when the State of Wu finally took the initiative to attack multiple ways; in the third year of Jiahe (234 AD), Zhuge Liang attacked Wei for the last time, and the State of Wu cooperated in the attack. Hefei was considered to be Sun Quan's sad place, attacking six times, and none of them succeeded, either losing troops or hitting the wall to withdraw. Of course, Sun Quan still had achievements, at least achieving Cao Wei generals like Zhang Liao and Man Yu. Because every time Sun Quan sent troops, he would lead soldiers 100,000 miles to send heads, so he was called "Sun 100,000".
Hefei's abandonment
Through these several battles, we can see that Sun Quan has been attacking Hefei, so why did it become Shouchun when Ding Feng and Zhu Yi rescued Zhuge Birthday? This matter is still the credit of The Wu Kingdom monster Ding Feng. Hefei is next to Chao Lake, and Sun Quan built a Dongxing causeway in Chao Lake in order to allow the Eastern Wu water army to play an advantage, so that the water army can land nearby to attack Hefei. Later, at the time of Sun Quan's death, the Wei army took advantage of the death of the State of Wu to launch an attack on Dongxing. Ding Feng, a big man in the military circles at that time, killed tens of thousands of enemies in the First World War. Therefore, in order to avoid the harassment of the Wu army, Hefei was abandoned and replaced by the Huainan defensive line centered on Shouchun.
It was also this strategy that Eastern Wu completely lost the opportunity to unilaterally seize Huainan. Without Huainan, Eastern Wu would never be able to advance into the Central Plains.
