Liaodong's Guanning Jin defense line, in fact, refers to the defense line from Dalinghe City to Shanhaiguan, with a total length of 400 miles, which covers Dalinghe City, Jinzhou, Songshan, Xingshan, Daxingbao, Tashan, Ningyuan, Gaotaibao, Qiantun and Shanhaiguan and other large and small cities and castles, the real formation of the Guanning Jin defense line is the period of the Apocalypse, created by the then military department Shangshu and Jiliao Governor Sun Chengzong, and the purpose of creating the Guanning Jin defense line is to resist the Houjin Tartars.

After the defeat of the battle of Salhu, the Ming court faced the Houjin has shifted from attack to defense, and Sun Chengzong, who presided over Liaodong affairs, saw this clearly, so he took defensive measures to build a castle and strengthen the city, and when Sun Chuanting was forced to leave Liaodong, he had already suggested the construction of Dalinghe City, but unfortunately, the then Houjin Emperor Taiji found that after the construction of Dalinghe City, it would pose a huge threat to Houjin, so he personally led the army to attack Dalinghe City that was still under construction. Won the battle of Dalinghe City again.

Since then, the Guanning Jin defense line has been understood by everyone as the section of defense from Jinzhou to Shanhaiguan.

The credit of the Guanning Jin defense line cannot be erased, although the Eight Banners Army is brave, often entering the pass to loot, the imperial army is not the opponent of the Eight Banners Army at all, but due to the solidity of the Guanning Jin defense line, the Houjin Tartars who plundered in the pass did not dare to stay for a long time, and eventually had to return to Liaodong.

It can be said that the Guanning Jin defense line effectively protected the capital of Daming, if there was no Guanning Jin defense line, Daming would have fallen early ago.

During this period, there were also many changes, that is, the rise of the Zheng Family's army, which made the Later Jin Emperor's Emperor Taiji and the Eight Banners Army taboo, and even fearful, because every battle between the Eight Banners Army and the Zheng Family's Army ended in failure.

Now. The Guanningjin defense line no longer exists, and the Eight Banners Army occupied all parts of Liaodong, only Shanhaiguan was still in the hands of the Ming court.

Relying only on Shanhaiguan, the safety of the capital of Daming is difficult to fully guarantee.

Although Zheng Jiajun was unusually brave, he could not allow others to snore next to the couch, watching the Eight Banners Army occupy the entire Liaodong. Zheng Xunrui is impossible to bear, he has been on the throne for more than a year, because to stabilize the north and stabilize the entire Ming Dynasty, Zheng Xunrui has no energy to conquer Houjin for the time being, and now the time is ripe, the Zheng family army, which is strong and strong, must attack, the purpose of this attack. It is to completely exterminate the Qing Dynasty.

The first phase of the Zheng Jiajun's combat mission was to recover the Guanningjin defensive line.

Zheng Xunrui carefully analyzed the defense line of Guan Ningjin.

In terms of geographical location, the two cities of Ningyuan and Jinzhou are the most important, occupying these two cities, you can take into account other cities and castles in Liaodong, and the two cities can echo each other, so that the invading opponent can take care of one and lose the other.

There were not many steep places to garrison the Guanningjin defensive line, only the city was relatively strong.

Other words. The Zheng army launched an offensive from Shanhaiguan, and it was not particularly difficult to recover places such as Qiantun and Gaotaibao. However, the recovery of Ningyuan may encounter major difficulties.

The Jiliao Governor's Mansion was set up in Ningyuan City, and Yuan Chonghuan, the governor of Jiliao, was stationed in Ningyuan.

Once Ningyuan is taken, then Xingshan, Tashan, Songshan and Daxingbao, which are not far away, will lose their support and be difficult to garrison. In the end, the remaining lonely city of Jinzhou is also difficult to hold.

Before the departure of the army, Zheng Xunrui summoned many of the general soldiers, deputy general soldiers and generals of the Zheng family army who were about to follow him to discuss the combat deployment for the last time and participated in this discussion. There are also Xu Wanghua, the first assistant of the cabinet, Zhou Yanru, the second assistant of the cabinet, and Xiong Wencan, the minister of the cabinet and the secretary of the Ministry of War......

July is the hottest season of the year.

Ice cubes were placed in the Qianqing Palace, which was specially prepared by Liang Xingli, the Minister of the Interior.

However, these ice cubes were quickly withdrawn, because the emperor entered the Qianqing Palace, and after seeing these ice cubes, he spoke, and the army was about to start the expedition, and the expedition faced too many difficulties, and the upper and lower sides must share weal and woe, and after a while, many generals of the Zheng family army will come to discuss the deployment of the operation, such a critical moment, the Qianqing Palace to prevent the ice from cooling down, what kind of system, quickly remove these ice blocks.

However, Zheng Xunrui is still not mechanical, he asked Liang Xingli to send all these ice cubes to the harem, so that you can use them and princesses, after all, the temperature is too high, and you can use ice cubes to lower the temperature, and people are more comfortable.

Zheng Jinhong led everyone into the Qianqing Palace.

Everyone saluted the emperor.

A huge map of Liaodong has been hung in the middle of the main hall, with arrows marking the situation of the Eight Banners Army's stationing, as well as the route of Zheng's army's attack, and so on.

Zheng Xunrui walked to the front of the map and looked at the map, looking calm.

Xu Wanghua and the others had sweat drops on their foreheads, this weather was indeed hot, but seeing that the emperor was also dressed neatly, it was not easy for everyone to wipe their sweat.

"Zheng Jinhong, let me introduce you to the initial operational deployment."

Zheng Jinhong nodded and walked to the front of the map.

"According to the operational deployment formulated by the emperor, the 150,000 troops of the Zheng family army will launch an attack from Shanhaiguan, and the first phase of the combat mission is to recover the Guanningjin defense line and completely wipe out the Eight Banners Army stationed in the Guanningjin defense line."

Zheng Jinhong held a bamboo whip in his hand and first pointed to Qiantun, the closest to Shanhaiguan.

"The army must completely recover the Guanningjin defense line within two months, and recover all the castles and lands within 400 miles from Shanhaiguan to Dalinghe City, and the first city that the army marches out of is Qiantun."

"According to the information provided by the Investigation Bureau, there are 5,000 Eight Banners stationed in Qiantun, and the Khan Eight Banners are the mainstay, and the Zheng Jiajun wants to conquer Qiantun, the problem should not be big, according to the estimate, the army will take Qiantun within two days, which should be expected."

"The first hard bone of the Zheng family army is Ningyuan, according to reliable information, the Qing Dynasty's Raoyu County King Abatai is stationed in Ningyuan City, its official office is the former Jiliao Governor's Mansion, and the total number of the Eight Banners Army stationed in the city is 60,000 people, and this is also the key defense place of Abatai, once the Zheng family army takes Ningyuan City, it is equivalent to basically recovering the Guanningjin defense line......"

When Zheng Jinhong introduced the situation, everyone listened very carefully, and although everyone in the Qianqing Palace knew about the basic situation of the operational deployment, no one dared to underestimate such a major operational deployment.

Zheng Xunrui fell into deep thought, as if he hadn't listened to the many situations that Zheng Jinhong said.

According to the overall operational deployment, after Zheng Jiajun set out from Shanhaiguan, he adopted a step-by-step combat plan, that is, from Shanhaiguan to the north, the recovery of one city after another, and the recovery of inch by inch of land, this is a face-to-face fight and collision, showing the strength of both sides.

The advantages and disadvantages of such a combat deployment are very clear, and the advantage is that the strength of the Eight Banners Army is consumed step by step, and at the same time, the confidence of the army can be boosted to the greatest extent, the ambition of the people of the Ming Dynasty can be boosted, and the influence of gold-phobia can be eliminated from the root.

The downside is that the progress of the battle is definitely slow, and it takes time to conquer every city and castle, and the cost is enormous.

There is also a favorable place, that is, Huang Taiji sent part of the Eight Banners Army into the grassland to conquer, the troops are somewhat scattered, the Zheng family army launched an attack from Shanhaiguan, Huang Taiji must withdraw troops from the grassland, concentrate the army to Liaodong, and start a decisive battle with the Zheng army, it takes time to withdraw the troops and march, Zheng Jiajun can seize this time difference, and wait until the reinforcements of the Eight Banners Army arrive in Liaodong, the Zheng family army may have achieved many victories and recovered a lot of places.

When this plan was first discussed, Xiong Wencan proposed that the Zheng Jiajun and the Eight Banners Army were likely to fight in Jinzhou and other places in eastern Liaodong, but this prediction was denied by the emperor.

Zheng Xunrui believed that Huang Taiji would never ask the Eight Banners Army to fight a decisive battle with the Zheng Army in Jinzhou and other places, because the focus of the Qing Dynasty was not within the Guanningjin defense line, and their focus was on Shenyang and Liaoyang east of the Liao River.

Therefore, according to Zheng Xunrui's prediction, the battle to recover the Guanningjin defense line will be fierce, but it will not be a decisive battle.

In short, Zheng Xunrui's analysis believes that Zheng Jiajun's recovery of the Guanningjin defense line is a sure thing, and the Great Qing Kingdom and Huang Taiji will not invest heavy troops in Guanningjin, let alone do their best to help the Guanningjin defense line.

It is precisely because of Zheng Xunrui's analysis that when Zheng Jiajun fought in the first stage, he would not invest all 150,000 troops, and the focus was on the 50,000 former army.

As for the 100,000 Chinese troops, the main task is to stabilize the situation in various parts of Liaodong.

After Zheng Jinhong finished speaking, the Qianqing Palace fell into silence, and everyone found that the emperor was in deep thought.

Whenever such a situation occurs in the emperor, it means that new ideas have emerged, that is to say, the emperor is thinking about it, preparing to adjust the combat deployment, or putting forward other suggestions and opinions.

After so many years, all the soldiers of the Zheng family army have a natural reverence for the emperor, and every time the emperor who commands the battle falls into contemplation, it is when the opponent is going to suffer.

A full quarter of an hour passed.

Zheng Xunrui raised his head and looked at the map, his face became grim.

"Just now, Zheng Jinhong has given a detailed introduction to the route of the army's expedition and the arrangement of the combat time, do you have any other opinions?"

is still silent, and no one will easily think of changing the operational deployment that has been decided, unless the emperor directly proposes to change the operational deployment.

Zheng Xunrui took the bamboo whip from Zheng Jinhong's hand and pointed directly at Jinzhou and Dalinghe City. (To be continued.) )
