The revival of Shu Han

Chapter 481 Luoyang is Luoyang ([-])
In the history of European warfare, the defenders first relied on wooden fences or stone fortresses for defense, but the appearance of trebuchets and primitive artillery made these two fortifications a decoration.Then the bastion came into being.All of a sudden, because the shield far exceeded the spear, the land of Europe was full of fortresses and small countries.

How to solve the bastion when the artillery technology is not yet fully mature, European military scientists have made persistent explorations for this.In the 70s, the French Marshal, military engineer, and founder of the modern engineering army - Sebastian Le Presde Vauban proposed the trench siege system.It effectively solved the major issue of how to take down a bastion with complete defense forces under the condition of limited attacking artillery power.

To put it bluntly, this system is: digging trenches, digging trenches out of the system, digging out art.

The specific excavation method is as follows: first dig a circle around the target to be attacked, and pile the excavated soil towards the side of the target to form a low wall to protect the engineers on the side.Then, based on this circle of trenches, dig a zigzag-shaped trench. After digging to a certain extent, dig a circle of trenches closer to the enemy's city wall.Then start to attack the opponent's wall or the artillery (catapult) on the wall with your own artillery or trebuchet.If it doesn't work, repeat the above steps until you gradually approach the opponent's city wall.

During this process, due to the protection of the trenches, the enemy troops on the top of the city were basically unable to effectively kill the engineers digging the trenches.In the same way, because of the protection of the trenches, it is basically safe for our own siege vehicles, trebuchets, artillery, etc. to move in the trenches and gradually approach the local city walls.

Moreover, as the trenches gradually approached the enemy's wall, all the enemy's defenses on the wall would be weakened more and more because of the angle.No matter how strong your city wall is, I have dug to the bottom of your wall, so what chance do you have for struggling?

In the historical plane, in the middle of the 20th century, the Taizu of this dynasty and Duke Kaishen competed in the Central Plains.Faced with the many reinforced concrete systems of the Guodang, the Chinese army often used super-strong civil engineering to break down the enemy's defenses.This is actually a variant of the Vauban trench system.Therefore, the genes of this dynasty's infrastructure madman have been fully revealed as early as the founding of the country.

"This trench system is roughly like this, do you understand it?"

"Don't worry, the head of the mountain, the students have fully understood."

At this time, Li Xiang and Li Zhanfei, Guan Yi's favorite student, had been promoted to the position of Zhonglang Jiang.Although the prefix of this Zhonglang general is the unprecedented "engineering soldier", Li Xiang, who has fully matured at this time, no longer has the desire to return to the Zhanbing series.Because, he has been deeply infatuated with civil engineering.

"Well, this system needs to be completed quickly, and manpower is the foundation. You and your subordinates should first investigate the soil quality outside Luoyang City and calculate the project volume. In the middle and late this month, I will give you [-] captives as the teacher, which should be enough right?"

"Hehe, thank you Shanzhang. I've grown so big, I haven't managed so many people. But the Shanzhang really can't bear it. Such a good method, I have been holding back until now." Li said a few words Xiang quickly said solemnly: "Don't worry, the head of the mountain, as long as there is enough food, the students can guarantee that these captives will also be able to handle things very well."

"Hmph! As a teacher, I have endured until now because of a strong city like Luoyang!" After saying this, Guan Yi hugged Li Xiang, and said in a low voice: "As a teacher, I am a dark son in the Eastern Wu court. I sent reliable news that that idiot Sun Hao is planning to mobilize more than 10 troops from Nanyang County to the north to break the siege of Luoyang after their autumn harvest in August and September this year. Well, although Wu Gou’s combat effectiveness as a teacher has never been taken seriously But that’s [-] people, it’s exhausting to cut off heads one by one..."

"Students understand. Students immediately lead people to start doing things."

My boss and teacher has set a deadline for myself, so what else can I say?Get busy now.

……

Beginning on March 9 of this year, more than [-] prisoners of the Jin State under the control of the Han army came to Luoyang one after another.

On April 500st, Li Xiang, who completed the geological survey and blueprint design, with the help of many lieutenants and military lords under his command.The distribution section of more than [-] prisoners of war was completed.Then the engineer Zhonglang gave an order, and more than [-] prisoners of war mobilized together.Digging of trenches began at a distance of [-] meters from the outer wall of Luoyang.

In front of these prisoners of war, nearly [-] Han troops lined up to protect and monitor the working personnel.

500 meters, has exceeded the maximum range of the trebuchets, bows and arrows at the head of Luoyang City.Therefore, in the face of this move by the Han army, the soldiers and civilians in Luoyang City could only watch besides watching.

"What is Han Guo doing?"

"Could it be to dig a tunnel?"

"But how could digging tunnels be so obvious, no, huge..."

Don't say that Du Yu, Ma Long and others are ignorant, they have caused a lot of trouble to the traversers.It's a pity that this is the gap of the times rather than a problem of personal ability.

Besides, they are now deprived of military power long ago, and have become idlers who don't care about it.

Yes, after all, it was the enemy army approaching the city, so at this time Sima Yan once again lifted the military power of all generals with different surnames.Instead, all the troops were led by members of the Sima family.

The current defense leadership organization in Luoyang City is composed as follows:
Commander-in-Chief of City Defense: Emperor Sima Yan personally led the [-] Prince Guards.

Executive Commander-in-Chief: Marshal of the Army and Horses of the World, Director of Military Law, Sima You, King of Qi (responsible for being a villain, such as punishing a prince who is weak in defense)

Deputy Commander-in-Chief: General Fuguo, King Sima Jun of Ruyin, General Huguo, King Sima Gui of Taiyuan (each commanding [-] troops as reserve troops)
The person in charge of the city gate: the nine Sima led by Zhao Wang Sima Lun... each led more than 4000 soldiers and five or six thousand civilian husbands, forming nine teams of 2 people, responsible for defending the nine gates of Luoyang.

Apart from these thirteen Sima, only two have real power:

First, Jia Chong, the chariot and cavalry general.Mr. Jia Gonglu's duty is to mobilize all the personnel in Zoucao, closely monitor all officials and people in the city, and prevent these people from cooperating with external enemies.Among them, the key monitoring object: Shang Shuling Pei Xiu.

Second, the servant of Shangshu shoots Yang Zhen: responsible for the management and distribution of logistics materials.

It's normal and reasonable to do so.It just completely broke the hearts of a group of generals with foreign surnames.If this battle is lost, these guys will willingly surrender to Ji Han.If you win, well, if you win, you win.In the future, let the people of Sima's family do the work of regaining the lost land.

Besides, in the hearts of Du Yu, Ma Long and others, they were in awe of Jiang Wei: because in this world, no one has ever defeated Jiang Wei under the condition of equal strength.But they have a way to make Jiang Wei return without success.

But for Guan Yi, it was complete despair.Because this guy doesn't look at the war stupidly and has no sense of beauty.However, counting the battles he commanded, it is more and more inclined to defeat Wei and Jin in the way Wei and Jin are best at: logistical crushing.

Standing on the top of the city, Du Yu looked at the prisoners of war who were digging trenches below the city for a long time, and made a gesture to Yang Hu. Yang Hu bowed his head and dropped his ears, only to hear Du Yu say in a low voice: "How do I feel, Emperor Xuan His descendants will eventually perish in Emperor Xuan's art of war."

　Stalin said that there are four elements of a nation: a common region, a common language, a common script, and a common belief or spiritual value.The reason why Eastern and Western civilizations were eventually unified in China was that there were many small countries in Europe.Words play too much role.The West is spelled with letters. As long as two places that are close to each other have slightly different pronunciations, two languages ​​may be developed, and then two nations and two countries may be formed.And I, Huaxia, use square characters. People from Sichuan, Northeast people, Cantonese people, Fujian people have different pronunciations for "yes", but they all write out one word.Therefore, the significance of square characters to our country and nation can be seen from this.
