After learning that the Dongjiang Army, led by Mao Wenlong himself, had once again conquered Longchuan and Yizhou, and almost wiped out all the Jianlu who stayed here, Zheng Fengshou and others rejoiced, and held a banquet for Guo Dajing and other generals that night.
Since you took up swords and guns to resist the invasion of Jianlu, you must have the consciousness to sacrifice yourself for your country.
Although the deaths of Yue Tuo and Shuo Tuo are related to Longgu Mountain City, it is very likely that they will incur revenge from Jianlu. Zheng Fengshou and others will not complain about the Dongjiang Army. Do they need to be measured in fighting?
Therefore, Zheng Fengshou and others must rely more heavily on the support of the Dongjiang Army, not only in terms of military strength, but also in terms of food and supplies.
"If you can defend, you will defend. If you cannot defend, you will abandon the city and escape into the mountains and forests, and continue to deal with the rebels." Shang Kexi conveyed Mao Wenlong's advice to Zheng Fengshou and others, "Fight to the end, Marshal Mao thinks it is not in line with the art of war."
Zheng Fengshou put down his wine glass and said thoughtfully: "General Mao will appreciate Commander Mao's concern. If we build tens of thousands of captives, I will not continue to defend it."
There were tens of thousands of captives, and the entire Dongjiang Army was dispatched, but they were unable to engage in a head-on battle.
Guo Dajing's expression remained unchanged, he chewed the meat in his mouth, raised his wine glass, and said with a smile: "The military book I asked for from Mr. Zheng has benefited Guo a lot, but he has not yet thanked Mr. Zheng for the gift of the book.
Woolen cloth!"
Zheng Fengshou laughed and said: "The book has been gathering dust in Zheng's house for a long time. It almost burned a fire to keep warm. It is really a pearl cast in secret. It is in the hands of Guo Baihu that it shines brightly. It is also its creation. It is too polite to say thank you.
.”
Guo Dajing still expressed his gratitude to Zheng Fengshou, took a sip, and said: "It's a pity that Guo doesn't know much about literacy, so he always asks others to read, listen, or even explain. There is a sentence in it that is very well explained, and I remember it most firmly.
.”
Oh, Zheng Fengshou has a lot of social experience, how could he not ask and flatter him at this time?
Guo Dajing scratched his head and said solemnly: "If you save people and lose land, everyone will gain land; if you save land and lose people, everyone will lose land."
The banquet became quiet, and North Korean generals such as Zheng Fengshou and Cui Xiaoyi, including Shang Keyi, Liu Xingzuo and other generals of the Dongjiang Army, also stopped eating and savored the essentials of military strategism that they had never heard of before.
After a long while, Cui Xiao praised him and said: "Incisive, this explanation explains the gains and losses of "not fighting for a city or a land" in a profound and unforgettable way. Just understanding this sentence thoroughly can still be regarded as the qualifications of a famous general."
Zheng Fengshou suddenly realized it. After thinking for a long time, he raised his glass to Guo Dajing and said: "It's like an enlightenment. Zheng has been taught. Please, Zheng, give Guo Baihu a drink."
"That person explained it well. But a lot of people asked me for advice, but I forgot which expert it was." Guo Dajing grinned and raised his glass to continue drinking. The look on his face could not be seen to be fake at all.
Everyone probably knew that Guo Dajing had reservations, and they didn't know whether he had realized it himself or someone else had taught him. They continued drinking and eating, and the atmosphere became more lively.
Obviously, Zheng Fengshou was relieved, accepting Mao Wenlong's suggestion and no longer regarded defending Longgu Mountain City as his main purpose.
Defending to the death is not much different from defending to the death. In Guo Dajing's opinion, the troops are insufficient and the fighting power is not strong. Although Longgu Mountain City is dangerous, in the end it is passively beaten.
When fighting in Korea, the Koreans should take advantage of their familiarity with the terrain and use rivers, mountains and forests to flexibly attack the rebels.
Each battle does not require a big result, but it needs to be frequent, so that small wins can lead to big wins.
If Zheng Fengshou can be persuaded, the Dongjiang Army and the Korean volunteers can cooperate in fighting and take the initiative to harass the Jianlu. This is more advantageous than standing guard in Longgu Mountain City and waiting for the Jianlu to attack.
After having enough food and wine, Guo Dajing and others were arranged to rest in a comfortable residence.
Early the next morning, Guo Dajing and Liu Xingzuo had breakfast, then left the city with their guards and rushed to the camp. Following them were several carpenters who had asked Zheng Fengshou to come.
"If you save people and lose their land, everyone and the land will be gained; if you save the land and lose people, everyone will lose their land." Liu Xingzuo looked at Guo Dajing with a half-smile, and said, "That expert, can you tell a certain family?"
Guo Dajing shook his head like a rattle and said, "Don't say it, don't say it. If it leaks out, he shouldn't teach me."
Liu Xingzuo laughed and did not go into details anymore, but he had his own guess in his heart.
There were only a few people who could follow Guo Dajing, but none of them seemed to be that material. It was not surprising that a guy who could come up with a plan to alienate someone could understand the penetrating words from the military book.
But Liu Xingzuo is a scheming person. If Guo Dajing refuses to come forward, he will naturally not expose him. Pretending to be confused is the best way to get along with him.
"Are you bringing these carpenters to build that trebuchet?" Liu Xingzuo changed the topic and asked curiously: "It's awesome. How does it compare to the wooden cannon?"
Guo Dajing thought for a while and said, "I think it's hard to compare. They all have their own strengths. Of course, we have to build them and see. I don't know how powerful they are."
Liu Xingzuo nodded and said: "I know nothing about trebuchets. I have never seen one in the army, which is very strange."
Trebuchets were indeed rarely used in the Ming Dynasty. After Chengzu, there were no records, which is very strange.
Although artillery was already available at that time, its power, especially in siege operations, seemed to be inferior to that of large trebuchets.
The appearance of the Hongyi cannon was not until the end of the Ming Dynasty, and it was the most powerful weapon in siege.
In fact, Guo Dajing didn't fully understand the trebuchet, at least he didn't know all the principles of its power to destroy the city wall in the movie.
For example, Western castles in the Middle Ages were often built with solid stone. If you want to use a trebuchet to destroy the city wall, you need a stronger throwing object.
Therefore, in actual wars, such as the Crusades, special solid stones often need to be transported over long distances in order to destroy city walls.
Of course, what Guo Dajing wants to build is a light trebuchet, which can throw mines or ordinary rocks. The lack of knowledge will have little impact.
Back at the camp, Guo Dajing and the carpenters got busy. He didn't draw any drawings, he just made gestures and instructions. He built them first and tested them before improving them.
Guo Dajing's thought was quite correct. The structure of the trebuchet was not complicated and the basic frame was fixed.
A movable long arm is connected to the axis of the frame. One end of the long arm is a bomb bag for loading thrown objects, and the other end can be pulled by a rope or a counterweight.
The counterweight-type trebuchet is slightly more complicated, and the long arm must be pulled down first before use, which reduces the ejection efficiency compared to manual traction.
But Guo Dajing had already made the choice to build a counterweight type.
Firstly, the range and weight of the thrown objects of the counterweighted type are much higher than those of manual pulling; secondly, the landing point of the counterweighted type is relatively fixed, and manual pulling is difficult to control.
During the manufacturing process, Guo Dajing also simplified the work. If the counterweight is about five or six hundred kilograms, there is no need for a winch to pull down the long arm, and it can be done manually.
Anyway, Guo Dajing just wants to be quick, quick to build and quick to use. Time waits for no one, and there is no room for too much precision.
Many soldiers were also mobilized to do the rough work, while the fine work was given to carpenters, which greatly speeded up the manufacturing process.
As dusk approached, a crude trebuchet was finally built. Some of the wood didn't even have the bark removed. It would be an exaggeration to say that it was crudely made.
Guo Dajing was impatient and ordered the personnel to lift the trebuchet to an open area. He had no choice but to do it quickly, and even the wheels were not installed.
"Three hundred kilograms first." Guo Dajing was still very careful, fearing that adding too much counterweight would cause the trebuchet to fall apart again.
After more than 300 kilograms of counterweight and about 20 kilograms of thrown objects were all ready, Guo Dajing personally smashed the hook.
One end of the counterweight suddenly dropped, and the long arm swung, drawing an arc in the air, causing the ammunition bag to fly up. The thrown object broke away from the ammunition bag at the highest point, and was thrown diagonally into the distance under the action of centrifugal force.
Bang! The thrown object hit the snow in front of everyone's eyes, stirring up snow dust.
"Flying quite far." Liu Xingzuo nodded vigorously, took the bow and arrow, opened the bow and shot in the same direction.
The strong bows used by Jianlu at that time could reach a range of more than 200 meters if thrown at a 45-degree angle. However, when the arrows reached this distance, they did not have much lethality.
Therefore, the effective range of a bow and arrow is usually about one hundred meters, and it requires a relatively powerful archer.
The arrow shot by Liu Xingzuo exceeded the throwing distance of the trebuchet. But Guo Dajing estimated that it was only about forty meters beyond.
Well, there is great hope!
Guo Dajing was very excited, and asked someone to increase the weight to 500 kilograms, and threw it again. It was still not enough, so he added another 800 kilograms!
Very good, the throwing distance this time is very close to that of a bow and arrow. In other words, it is almost two hundred meters.
Guo Dajing laughed and said, "If you make it more precise, you can throw it further."
In fact, the heavy objects thrown by the ancient trebuchets were as light as fifty or sixty kilograms, and the range could reach more than two hundred meters. The crude goods produced by Guo Dajing's command could only throw twenty kilograms at a similar distance.
about.
But Guo Dajing did not have this consciousness, but he was complacent. The key point was that he did not expect to use trebuchets to attack the city, but to hit people.
What's wrong with twenty kilograms? He still wants to use ten rocks weighing about two kilograms.
A trebuchet throws ten pieces, and ten is a hundred pieces. If there are dozens... have you ever seen the spectacular sight of hundreds of stones flying densely across the sky, covering people and hitting people?
Of course, the heavier the stone, the greater its lethality. Even if it is held against a shield, a 20-pound stone can be knocked down with a bang, right?
For details, please refer to the hazards of falling objects from high altitudes: a flower pot (1kg) dropped from the 10th floor (30 meters), with lethality comparable to that of a gunshot; eggs dropped from the 18th floor can break a person's skull; watermelon rinds...
Liu Xingzuo didn't know the messy data Guo Dajing was thinking about, but he was surprised and excited by the power of the trebuchet.
It's not suitable for attacking, but if a sufficient number of trebuchets are deployed behind the defensive position, and thousands of thunders or tens of thousands of stones are fired, it will be - quite spectacular!
Patting Guo Dajing's shoulder hard, Liu Xingzuo extended his thumb and praised: "Awesome, this was taught by that master again? Can you tell me your surname?"
Guo Dajing was also excited and blurted out: "Newton, specializes in the study of motion."
Liu Xingzuo blinked his eyes, very confused and puzzled. Judging from Guo Dajing's expression, it didn't look like he was making up nonsense. But this name was very weird, and he had never heard of it before.
Guo Dajing also realized that he was at a loss and smiled at the stunned Liu Xingzuo, showing two white teeth.
Liu Xingzuo shook his head helplessly, not wanting to talk any more. He might have said that he was just making it up, but it was a bit true, and he even confused himself.
Guo Dajing pretended to be hurt and stunned, but others couldn't understand him anyway.
After messing around, he asked the craftsmen to measure the dimensions again and make them according to these specifications. He continued to experiment, mastering the weights of different weights and the range of the thrown objects, and recording the approximate impact point.
Accuracy is out of the question. The error is acceptable within a dozen meters. It is not a precise strike anyway.
Guo Dajing enjoyed it endlessly, watching the stones flying through the air one by one and hitting the snow heavily, feeling full of accomplishment.
Finally, when the counterweight reached 1,500 kilograms, the crude trebuchet was broken by playing with it.
"There's no time to play!" Guo Dajing spread his hands towards Liu Xingzuo and said with a smile: "Eat and rest. It's been a tiring day."
Liu Xingzuo rolled his eyes and said, "Someone brought you food. I saw that you were having fun and didn't bother you."
Ah, and what about this kind of treatment?
Guo Dajing looked around and saw Fujino Hide. A smile appeared on Fujino Hide's black face, with a few prominent white teeth, and he waved to him.
Liu Xingzuo patted Guo Dajing's arm, nodded with a smile, turned around and left.
This smile is a bit malicious!
Guo Dajing blinked his eyes, ignoring this, feeling hungry, and walked quickly towards Fujino Hide. Regardless of whether this guy was male or female, his cooking skills were still good, much better than the food in the army.
"Trebuchet, or trebuchet?" In the tent, Fujino Hide asked curiously while heating food: "It seems very powerful."
Guo Dajing sniffed, the smell of rice came, and he became even hungrier, so he casually said: "Call it a trebuchet. It's a very ancient weapon, and it's not very powerful. It has long been outdated and has been eliminated by the army."
Fujino Hide smiled and said: "Being old does not necessarily mean that you are not powerful! Swords and guns are more ancient, aren't they still in use?"
Guo Dajing nodded repeatedly, what he said made sense. Weapons depend on their suitability and flexible use, but the more advanced they are, the more powerful they are.
No matter how advanced the muskets or artillery are, they may not be suitable for every battlefield, let alone win the battle.
"That theory that only retains ground but loses people is astonishing!" Fujino Hide's Chinese is good, but some idioms are not used very appropriately.
Guo Dajing laughed, took the job handed to him, and said: "It sounds very profound, but it's actually just made up."
Picking up the chopsticks, Guo Dajing politely gave way: "Let's eat together!"
Fujino Hide shook his head with a smile and said, "I ate in the city. Don't be polite. I brought it to you." After saying that, he stretched out his hand and said, "You eat, and I will read you the book of war."
That's fine. It would be better if we could have some accompaniment during the meal. It would be better if we could play the piano and sing a tune or something.
While Guo Dajing was eating, he listened to Fujino Hide reading the Military Book. It was helpful to open the book. Guo Dajing felt that it was not in vain to listen, but he could also gain some posture.
Fujino Hide was reciting, maybe because habits are hard to change, his rough voice became clearer, but he didn't notice it yet.
