There is such a law that as long as there are forces to establish a dynasty in Jiangdong, Zhenjiang will be regarded as an important military town to protect life.

He Zhi? Because not far from Zhenjiang is Nanjing, the capital of Lishi country in the Southern Dynasty (formerly known as Jianye, Jiankang and Jiangning). Although the Southern Song Dynasty had its capital in Lin'an, Nanjing was the gateway to Hangzhou and Zhenjiang was the gateway to Nanjing.

The capital of the Three Kingdoms, Soochow, was under construction, but when the battle of Chibi was decided, the capital of Soochow was in Zhenjiang, which was called Jing. It is called Jing because there is Jingxian mountain nearby (south of Jiaoshan).

Liu Bei borrowed Jingzhou in the official history, and Liu Bei's blind date in Ganlu temple in the romance. All the well-known stories took place in Jingkou.

The capital history of Soochow in Zhenjiang ended with the extinction of Soochow, but after that, Zhenjiang still played an important role. Why? Geographical environment of Zhenjiang: Zhenjiang faces the Yangtze River in the north, and there are three famous Zhenjiang mountains on the south bank, namely Jiaoshan, Beigu mountain and Jinshan.

Jin, the famous fairy tale "water over the Golden Mountain", takes place here. Beigu mountain is the hill that Xin Qiji climbed. Looking north from the fence, "in the forty-three years, I still remember the beacon fire Yangzhou road."

Zhenjiang is close to water and mountains, and the terrain is very dangerous. It has become an important strategic barrier for the east line of Nanjing. If the northern army occupied Yangzhou, it would then go south from the North Bank of the Yangtze River. After seizing Zhenjiang, it would cut off the links between Nanjing and Changzhou, Suzhou and Zhejiang. The northern army can sweep through southern Jiangsu and form a strategic siege of Nanjing.

The importance of Zhenjiang to Nanjing, according to du you of the Tang Dynasty, is just like that of Mengjin (the Yellow River pass) to Luoyang. If the northern army captured Mengjin, Luoyang would have no danger to defend, and so would Nanjing. Therefore, the Six Dynasties (Eastern Wu, Eastern Jin, song, Qi, Liang and Chen) regarded Zhenjiang as an important defense town of the front-line army. It is equivalent to the gate of the vault. The gate of the vault is open. Before long, all the gold will be removed.

The ancients made it clear that if the military defense in Zhenjiang is slightly negligent, the danger in Nanjing is one point greater. In the early years of the Eastern Jin Dynasty, Su Jun made a riot, and Chi Jian, an important minister, took charge of Jingkou. At the same time, he refused to give up the idea of crossing the river in Jingkou and running to Guangling (Yangzhou prefecture). Because Xi Jian knew that once he abandoned Jingkou, the important places of money and grain of the imperial court, such as Wujun and Kuaiji county (Northern Zhejiang) to the east of Jingkou, could not be guarded. Hold Jingkou, even if the country fell, the Eastern Jin Dynasty still had a chance to make a comeback. Once Wu County and Kuaiji county were lost, Sun Wu and Sun Bin were resurrected and could not save the Eastern Jin Dynasty.

Liu Yu, Emperor Wu of the Song Dynasty and Xin Qiji, a generation of owls, said in his words, "in those days, gold and iron horses swallowed thousands of miles like a tiger." The former sentence is "setting sun, grass and trees, ordinary alleys, humanitarian slaves (Liu Yu's nickname) once lived."

Liu Yu lived in Jingkou? More than living. Now when people talk about Liu Yu, they will say that he is from Pengcheng after Liu Jiao, king of the Yuan Dynasty of Han and Chu. In fact, Pengcheng is only Liu's County hope, and Liu Yu's real birthplace is Jingkou. At the end of the Eastern Jin Dynasty, the powerful minister Huan Xuan abolished the Jin'an emperor and established himself as Chu. Liu Yu refused to accept Huan Xuan, so he plotted with all the heroes in Jingkou, finally killed Huan Xuan, and began the legendary road of being a hero.

After Liu Yu established the Song Dynasty, Jingkou's identity became emperor township. In fact, even if Jingkou was not Liu Yu's birthplace, Liu Song attached great importance to Jingkou defense for the sake of defending Nanjing.

Liu Song set up Southern Xuzhou in Jingkou, which is not large, but it is the first-line state of Liu Song. Liu Song has a rule: those who can be the assassin of Southern Xuzhou are basically Liu Song's clans, and outsiders are not qualified to guard Southern Xuzhou. It can be seen that they have an extremely important position. In the later dynasties, they are the same, unless they are trusted princes of the royal family, Otherwise, you can't be the assassin of Southern Xuzhou. Once outsiders control this place, it is equivalent to letting outsiders control the lifeblood of Nanjing. The Dynasty will play at any time, which will be dangerous. It can be seen that this is the lifeblood of the Pianan Dynasty in Jiangdong.

In the late Tang Dynasty, the imperial court set up observation envoys in Western Zhejiang, governing Southern Jiangsu and Northern Zhejiang, and the office was in Runzhou (now Zhenjiang). In the Southern Song Dynasty, not to mention, facing the strong military pressure of the Jin Dynasty, the Southern Song Dynasty concentrated its troops on the front line from Nanjing to Zhenjiang. The military significance of Zhenjiang is more important. Once the Jin army occupies Zhenjiang, the Jin army will take Nanjing in the West and Suzhou in the southeast, and then Hangzhou

In addition, Chen Liang, a famous poet in the Southern Song Dynasty, has a well-known "Nian nujiao Deng Duojing building", which is also on the Beigu mountain in Zhenjiang. There is a famous sentence in the word: "one water is horizontal, and the post is connected on three sides to make a competitive trend", which means Zhenjiang.

At the beginning of Jiatai's fourth year in the Southern Song Dynasty, Xin Qiji served as the magistrate of Zhenjiang and wrote the song "eternal joy - nostalgia of Beigu Pavilion in Jingkou" on Beigu mountain.

Now this lifeline is in the hands of Liu Jiajun. Liu Bu continuously transported materials from Guazhou on the North Bank of the Yangtze River and unloaded them here as a bridgehead for attacking Nanjing.

The east gate of Nanjing is Zhenjiang, led by Liu Bu, the west gate is Anqing, attacked by General Liu Zhongyong, and Luzhou is the north gate! Most of the southward advance of the North broke through the natural graben of the Yangtze River from Jiujiang. The civil strife in the south must seize Anqing. If the southern Northern Expedition, it must take Luzhou, Anhui and Henan.

It goes without saying the importance of Zhenjiang to Nanjing. Everyone knows and understands it. Therefore, when Liu Jun captured Zhenjiang, the news was conveyed to Nanjing, but it caused a huge shock and blow to the whole city of Nanjing. It can be described in one sentence: the sky collapsed.

Because everyone knows that if you want to hold Nanjing, you must hold Zhenjiang. When Zhenjiang is lost and the east gate is open, the enemy is coming under the city. Sure enough, when the fall of Zhenjiang comes, Liu Jiajun's iron cavalry appears near Nanjing.

This result, however, shocked and panicked the whole city and beyond.

It was originally said that after the appearance of Liu Jiajun, Duke Xu ordered to block the city, which has frightened and panicked the people in the city. Some powerful people have bribed the government and delivered their soft and family members to the outside.

Because everyone knows that since Liu Jiajun appeared in the south of the Yangtze River, Nanjing is the place he must take, and as long as he is not a fool, he can see that Liu Jiajun's mighty dispatch this time is mainly from Nanjing. After a visit to Nanjing, the south of the Yangtze River is what he has in his bag.

Moreover, Liu Jiajun's spies and spies are all pervasive. Their army has not arrived yet, but their spies have arrived first and spread all kinds of panic rumors. This kind of thing makes these people very panic and scared.

The real strength of Liu Jiajun is only 100000, but in the mouth of their spies, at least 500000 troops have been sent out, and the number of people on land and water has exceeded one million. Such a figure makes the people in the city afraid and panic.

Moreover, Liu Jiajun also took the opportunity to publicize their policies. At this time, Liu Bu's "crusade against Zhu Mingxi" has not been spread, but they have made clear their position, that is, those who follow us will prosper and those who oppose us will die. If someone dares to confront them, it will be a dead end. Moreover, they have announced that if they do not resist, they can preserve their lives and property, If you dare to insist on resisting the iron cavalry of the Liu family army, you will kill the city.

Don't mention that this policy would rather make the officials and gentry in the city very afraid and panic.

Liu Jiajun maintained the record of total victory. Since their rise, they have not defeated the war. They are invincible all the way. All the enemies let them down and bring them down.

So when they publicized such a policy, they shocked the local people so much that when Duke Xu was preparing his military pay, the gentry and rich households in the city questioned one thing one after another, that is, whether the officers and soldiers were able to defend Nanjing. If they were able to defend Nanjing, they would not mind donating military pay and food. If the Imperial officers and soldiers were unable to defend Nanjing, Simply withdraw from the city and don't harm the people of the whole city.

Hearing this argument, Duke Xu was very angry and angry. Now the enemy was coming to the city and was about to unite up and down against the enemy. This negative attitude actually happened, which was very bad for guarding the city and raising military salaries.

Duke Xu wanted to cut off the heads of several people to frighten people and suppress this failed thought.

But everyone knows one thing, that is, they all have power and power, and there is a backstage behind them. If it's normal, Duke Xu is absolutely not afraid of each other's small backstage. If he pulls out and cuts it, he will cut it. In terms of background and contacts, can anyone beat the Xu family in the Ming Dynasty?

But now, when the enemy is at the foot of the city and people are in panic, the more important thing is that he needs to raise military salaries through these people. If these people don't donate, he can't prepare enough military salaries.

Moreover, Duke Xu understood that he and his family were still here. If he sent his family out of the city like other officials and rich families in the city, it is estimated that the people and morale in the city will collapse.

This situation was not what he wanted to see. He had to assure the officials and gentry present that Nanjing was high and deep and heavily guarded. The officials and troops near the imperial court would arrive soon. As soon as the imperial army arrived, they would certainly defeat the enemy.

Duke Xu said: "Your family is here. If you move elsewhere, where can you go? When the enemy is coming to the city, we can only hold Nanjing City, our home and everything we have in front of us. Without Nanjing City, you are nothing and nothing, just like a refugee , instead of living like a mole ant, why don't you fight vigorously and fight a bloody road. "

After listening to the sonorous and powerful words of Duke Xu, the big guy was silent.
