I'm a big dick

Chapter 28
"Master Sun, this is the end of today's class!" Before Sun Chengzong could speak, the young emperor had already announced that the get out of class was over, and asked the palace servants to bring the sand table, and invited Sun Chengzong to watch it together.

When Sun Chengzong first saw the sand table, he was quite surprised, but when he looked carefully, it was the topography of Liaodong.Mountains, rivers, cities, etc. can be seen vividly, and the situation of the enemy and us can also be seen.

"This is made by the Chief Secretary of the Ministry of War." Zhu Youxiao approached and said: "The time is limited, and it is not completely detailed, but we can still see the general idea."

Sun Chengzong nodded in praise and said: "Your Majesty is wise and intelligent. This is to follow the example of General Ma Yuan of the Eastern Han Dynasty in 'gathering rice into valleys and drawing the situation', so that 'the captives are in the eyes'!"

Zhu Youxiao smiled, his face became serious, he took the wooden whip beside the sand table, pointed and said: "Master Sun, please look, this is Guangning, this is Dalinghe, this is Jinzhou, this is Ningyuan, this is Shanhaiguan..."

Aside from Guangning, what Zhu Youxiao pointed out was the famous Guanning Jin defense line in history, that is, Shanhaiguan passes through Ningyuan to Jinzhou.

Historically, the Guanning Jin Line of Defense was divided into two sections, the north and the south. The southern section was the Guanning Line of Defense, about [-] kilometers long, from Shanhaiguan to Ningyuan; Tashan, Songshan, Jinzhou, arrived at the Daling River.

Line of defense, as the name suggests, is a horizontal line to block the enemy's attack, so as to protect the city and people behind the line.Such as the Maginot Line, such as the Hindenburg Line.

However, the Guanning Jin Line of Defense is a vertical line, a series of fortresses extending from Shanhaiguan to Jinzhou, a total of more than 400 miles.Now, add Guangning who is fighting fiercely.

Well, at that time, the purpose of the Ming Dynasty building this line of defense was not pure defense, but to push forward with fortress tactics.

When Ningyuan is stable, it will be pushed to Jinzhou; when Jinzhou is stable, it will be pushed to Guangning; when Guangning is stable, it will be pushed to Shenyang.Donglu
at the door of his house, and then put Donglu in a nest.

This, the idea may be realized, but Donglu is a dead person, so he will let you continue to cultivate.

Therefore, in addition to swallowing gold like dirt and dragging down the economy of the Ming Dynasty, the Guanning Jin defense line in history played a very limited role.

What about the one-word long snake array, what should I do if I am cut off by the enemy, what should I do if I am surrounded by the enemy to fight for aid?
Historically, the Eastern Captives occupied Jinzhou three times and retreated voluntarily three times. They did not waste their troops here at all.

On the contrary, Daming, in order to maintain the Guan Ning Jin line of defense, increased taxes and taxes, causing civil unrest.

It was also because of the Guanning Jin defense line, the battle of the Daling River, the elites of the Ming army outside the pass were wiped out; the battle of Songjin, the elites of the nine sides were all empty...

There is a serious imbalance between investment and income, or even upside down, and the only way to do this loss-making business is when your head is flooded.

Since they don't have the ability to fight against Donglu in the field, the enemy can only close the city and let the enemy plunder around the city. How can we talk about offensive fortresses?
As for recruiting the Liao people to cultivate the fields to make up for the Ming army's rations stationed at Guan Ning Jin, it is even more taken for granted.

When the enemy comes, you retreat to the city, and the people in the fields may be able to hide in the city, but the grain that they worked so hard to grow is not all given to the enemy for nothing?

For example, in the Battle of Ningyuan, Ningyuan City was defended, but more than 7000 soldiers and seven to eight thousand merchants died on Juehua Island, and countless food and supplies were looted.

All in all, all in all, Zhu Youxiao has already planned to give up Guangning and Jinzhou and retreat to Ningyuan.

Since Donglu doesn't care about the Ningjin area, it means that this area is not that important.To put it bluntly, the so-called recovery of lost land is nothing more than taking over the no man's land between the two armies.

From a historical point of view, Zhu Youxiao suspected that this was done deliberately by Donglu.Set aside such a large area, just waiting for the Ming army to come.

Aren't you building a city? Build it! Build it!Don't you want to garrison troops to stockpile supplies, okay, okay!

When the Ming army was almost done, Donglu also dispatched.Either besieged the city to fight for aid, or robbed, killed and destroyed the city, and then patted their buttocks and left.

Instead of sending people's heads and supplies, repairing after being destroyed, and destroying after repairing, but only occupying a no-man's land of little value, and spending money to build a city and garrison, it is better to shrink directly to Ningyuan.

This plan is quite different from Xiong Tingbi's "abandon Liaodong and withdraw from the customs", except that Ningyuan is added as a barrier in Shanhaiguan, which is equivalent to double insurance.

Although it is a step further than Xiong Tingbi's strategy, Zhu Youxiao also knows that it will not be easy to implement.

Strategic contraction should be a good move, but on the other hand, it can also be said to be "losing ground and losing ground, retreating without fighting."

Therefore, Zhu Youxiao must take into account public opinion, the morale of the army and the people, and the reaction of the officials in the court.

The theory of quick victory and urgent battle is still very popular in Daming, and it can even be said to be the mainstream of public opinion.

This is especially true of the courtiers, either out of patriotic enthusiasm, or because they don't understand the actual situation in Liaodong, they clamor every day to "destroy the thieves". How can they accept the "traitorous" behavior of retreating without a fight?
Others don't say that Sun Chengzong, who Zhu Youxiao wants to entrust with important tasks, is a supporter of active offense.At the same time, Sun Chengzong was also the advocate and executor of fortress advancement, and the creator of the Guan Ningjin Line of Defense.

Because of this, Zhu Youxiao wanted to reveal it on the sidelines, trying to make Sun Chengzong change his mind and become his real help.

It's just that Guangning is still fighting at this time, and the outcome is unpredictable. Zhu Youxiao can't talk too deeply, and Sun Chengzong can't have the perspective of God like a time traveler.

"Your Majesty wants to implement Xiong Tingbi's three-party arrangement strategy?" Sun Chengzong asked with some doubts when he heard the young emperor mention that the west of Liaoning was neglected and the coast was emphasized.

Xiong Tingbi's three-party arrangement is: Guangning uses horse infantry to set up barriers on the river, attack the enemy based on the situation of mountains and rivers, and contain all the enemy's forces;
Tianjin, Hedeng and Laijian set up naval fleets to break into the enemy's southern garrison and shake their morale. In this way, the enemy is bound to have internal worries, and Liaoyang's recovery can be expected.

However, Zhu Youxiao's emphasis on western Liaoning and coastal areas is somewhat different from the tripartite arrangement.

The most important point is that he wants to abandon Guangning and the hundreds of miles between Guangning and Ningyuan, and station heavy troops in Ningyuan and Shanhaiguan, and take a completely defensive posture.

The purpose of defense is to buy time, save money, retrain elite soldiers, and eliminate disadvantages in domestic affairs in order to counterattack.This time will be relatively long, and Zhu Youxiao tentatively set it at five years.

Focusing on the coast is similar to Xiong Tingbi's, such as setting up naval forces in Tianjin and Denglai to harass and attack Hou Jin in the vast coastal areas, making him exhausted.

There is another point that Zhu Youxiao didn't say, that is, Dongjiang opened the town, and provided Dongjiang town with as much food, weapons and armor as possible, so that it can more effectively contain the Donglu, and let Mao Da's guerrilla leader add more merit.

Some people may express concern about Zhu Youxiao's strategic contraction.

Regarding the presence of the Ningjin defense line, it still can't stop the Donglu from bypassing the Great Wall and wreaking havoc in Gyeonggi.Wouldn't it be more convenient for the Eastern captives to attack by shrinking to Ningyuan or Shanhaiguan?
