It was a quiet night, but Guo Shao knew that the enemy soldiers were approaching and was expected to appear nearby tomorrow morning.
The soldiers who were not on duty all rested early, and even the personal soldiers standing at the central army were standing or sitting.
Guo Shao saw from the open tent and saw a soldier sitting next to the fire, holding needles and threads, silently sewing clothes on his body.
The soldier was very strong, but very young and looked just over teenage.
Guo Shao reached out and rubbed his neck, and continued to write and calculate on the paper on the simple chopping board.
The flat-fired copper cannon was built shortly after it was built, and the cannon watch was available.
The so-called gun table means that after the gun size, charge amount, and weight of iron pills are specified, the parabolic formula is used to calculate and test, and a table is made to compare the range of each elevation angle.
However, this cannon table is based on a flat ground table.
Now Guo Shao is temporarily calculating the gun chart at a slope of more than ten degrees. Because time is tight, he has just set up camp today, so it is dark and he has not calculated it yet.
...The original flat gun watch was made at the Tokyo schoolyard.
First, calculate the gravity acceleration. The data in the original formula cannot be used because the comparison conversion value of unit meters, seconds and actual measurement cannot be found.
The method is to re-expert.
Time measurement is an hourglass with a scale, in units of a snap of fingers (about equal to seconds); the length unit is zhang, size, size, centimeter, millimeter, and wire. When the so-called precision unit on the surface is ignored, with the current artillery technology and measurement tools, too small units are meaningless at all.
By measuring the time and height of the iron ball dropped from the pagoda, and taking the average value repeatedly, you can calculate the gravity acceleration.
Then the calculation of the initial velocity vector generated at the elevation angle is also very simple.Use a wooden protractor for the elevation angle. The trigonometric function value is just drawn to a triangle from the angle to model it, and multiply and divide the lengths of the figures on each side.
The cannon table made in this way not only has a simple comparison table, but also set formulas; if you find an angle that is not on the cannon table temporarily, you can quickly set the formula to calculate on the spot.
...When there is a slope in the actual battlefield, it can also be used to calculate the calculation using basic kinematic formulas to form a new gun table.
Regarding the measurement of the range length of the battlefield, Guo Shao probably remembers that he used gunshots in modern times; but now it is obvious that he cannot do it without this thing.His method is stupid.
Two ways are: one is to choose those with a strong sense of distance to estimate with your eyes, such as those who used to observe distances and used rock-throwing carts on the city walls when they were guarding the city.
Second, after using ropes to measure the integer distance on the battlefield, nail the wooden stakes, and when the war begins, they will be used as reference objects.
There are many wooden stakes on the slope in front now, which are nailed during the day, sparse.I guess the enemy doesn't know what to do because it has no defensive effect.
Just then, a man approached.Guo Shao was instinctively alert in a strange place. He looked up and found that a scholar wearing a round-necked green robe came over.
He ignored it, and suddenly remembered something, looked up and asked: Do you know how to read and arithmetic?
The clerk hurriedly bowed and said, "Your Majesty, villain will do it."
Guo Shao immediately waved over: Come and help me calculate.
The clerk walked forward carefully, glanced at the ghost-like talisman on the desk (with various symbols and Arabic numerals), and looked like he was about to cry on his face.
Guo Shao looked up and said, "Don't worry, I will teach you how to use the calculation process. You just need to calculate according to the process."
Guo Shao talked with him for a while, and the clerk gradually realized that as long as you add, subtract, multiply and divide a specific number.The clerk said goodbye and came out of the tent and took a little bit of abacus.
Soon, a skillful and quick-witted sound of slap sounds in the central army tent, and the clerk calculated very quickly... The abacus was like an ancient version of the calculator, and the efficiency was much higher than that of the pen. Guo Shao admired it deeply.
...Nothing happened overnight.As soon as the sky was dawn, Guo Shao woke up at the familiar rhythm of the drum and moustache outside the military camp, got up and put on his clothes and armor.A group of personal eunuchs took care of him.
Guo Shao asked: The enemy has arrived?
The clerk who helped him make arithmetic last night said: Go back to Your Majesty, his vanguard arrived as scheduled and occupied the high hillside to the west.
Guo Shao stretched out his arms, and the eunuch and the male eunuch hurriedly put the clean lining that was washed with green salt and washed the fragrance on him.
Guo Shao's expression was calm and calm, his eyes were calm but sharp, and his spirit was adjusted to his best condition.
He seemed very calm and asked the clerk: By the way, I forgot to ask you last night, what's your name?
The enemy soldiers approached the nose, and the emperor was still in the mood to care about a minor official, and his calmness infected everyone.
The clerk hurriedly replied: If you say that to Your Majesty, the villain is Zhang Yin, a native of Western Shu.
Guo Shao said: You speak very well.
With the help of everyone, Guo Shao quickly put on the refined plate armor and tied the dark purple cloak.He is not yellow in battle formations, it is too bright, and it is easy to attract the care of enemy soldiers in special circumstances.
The golden buckle belt was tied to the waist, and Guo Shao raised his sword and wore it.Then I washed and ate half full.
He walked out of the tent in a neat manner and stood on the slope for a while.
It was getting brighter at this time. In the early morning of early spring, the valleys were covered with milky white and shallow mist. Guo Shao looked up at the sky and the weather was very good today.
There was no dancing on the top of the mountain to the west. Guo Shao looked out and could see flags and figures standing on it.
Most of the people who stood on high places before the war were commanders and generals of the coalition forces.
Guo Shao had been there yesterday, and maybe his footprints are still there. Obviously, he guessed that Li Yiyin might be there too, and Guo Shao felt very close.
Different people will have different positions when standing on the same piece of land. What are Li Yiyin thinking now?
Guo Shao looked at it for a while, and the generals came to the central army one after another.The Imperial Guard's habit of fighting formations for many years has still retained a lot. He first came to the main general and finally deployed the battle formation.
Nearly a hundred people came, and almost all the generals above the commander arrived.While watching the battle formation opposite, everyone waited for Guo Shao to give the order.
Last night, the matter was discussed before the army and everything was planned as originally planned.Guo Shao spoke.
At this time, the generals gradually calmed down.
Guo Shao said: According to the facts in front of the formation, the generals can make a reasonable decision on the spot.However, copper cannons and grenade guns are not allowed without permission!Please remember clearly that the signal of using a firearm is "Ambushes on Ten Sides"; the signal of counterattack is "General's Order"!
The generals yelled and answered one after another.
Guo Shao paused.
I thought to myself, if a decisive battle is initiated like this, it is only if both sides are willing to do so. If the Dangxiang Khitan coalition forces are unwilling, can they concentrate their troops here?
This is an opportunity. Guo Shao is focusing on the cavalry of the coalition forces...especially the cavalry of the Liao army, because in his eyes, only the elite cavalry of the Liao army can be regarded as a qualified and organized cavalry army!
The Liao army's elite cavalry needed to tempt the war to truly begin.
Guo Shao's expression became solemn, and he said: The Imperial Guard is the most ingenious boy in Jiuzhou. He is the best in equipment, food and clothing, and is the most valuable and rich man of countless Han people!
These words suddenly became very serious, and the generals stood up straight in awe.People-oriented, it was because of the Tang Dynasty that I had thoughts, and Guo Shao's words were still very down-to-earth.
Guo Shao said loudly: The boys came here over mountains and rivers not to make a fool of themselves, but to make a fool of themselves, but to the face of the Han family, and not to let down my eager expectations and the people.For dignity, to protect the country and the people, and to every inch of the land left by our ancestors, I hope you will work hard to kill the enemy!
People responded one after another.
After hearing this, Guo Shao didn't say much and ordered: Prepare for war!
The generals shouted loudly: Serve for the Emperor!God bless my emperor and live forever!
……
There are army troops all over the mountains.Yang Gun looked at the momentum in front of him and said from the purged military appearance: The number of enemies is only one-third of us, but this is a fierce battle.
The number of Xu's infantry and cavalry deployed the formation here was only more than 40,000, while the coalition forces were about 120,000!
Li Yiyin said: Xu Jun came here first, why didn’t we choose the mountain we occupied but the place opposite?
Yang Gun didn't understand at all, and just said: But the opposite side is open and you can fight happily!
The coalition infantry and cavalry arrived at the battlefield one after another, with a larger momentum, with many people spreading horizontally wider. Gradually, the situation seemed to be a half arc, forming a semi-encirclement state on the sides of Xu Jun.
More than 160,000 people gathered here, with the ravines being extremely noisy and hustle and clouds, and the scene was very grand and spectacular.
The two sides had already clashed in the ravine between the two mountains, and the figure of the knight who pulled the bow crossed in the distance.
The coalition forces had an absolute advantage in number, and both Yang Gun and Li Yiyin decided to take the initiative to attack.Yang Gun suggested: The front slope is the slowest, and the front army infantry can get close to form a formation, and then dispatch infantry to attack.The cavalry protected the wings behind and remained motionless.
Although there are some preparations for training, the Dangxiang Army’s war horses may be uncomfortable in the face of the explosion of firearms. It is most appropriate to use infantry to fight the enemy infantry and military formations first.
Although Li Yiyin was the supreme commander of the main force, he also believed in the experience of the Liao army's long generals and adopted the suggestion.
Yang Gun said again: Xu's army has a smaller number, but the army is cleansed and cannot be captured at one time. You can replace the troops and take turns to attack.
After some preparation, the Dangxiang infantry and army moved forward from the hillside. They were also a square formation composed of groups of people, with different armors, many people carried bows and arrows, and their weapons were varied, but each of them also had a strong sense of strength.
The armor rate of the Dangxiang infantry in Hengshan is very high, but it is obviously unable to organize the blacksmith workshop to process the armor. The armor worn by the soldiers is mixed and they are all made at home.
Li Yiyin is still very confident. Indeed, he can't fight just by dressing well, but it depends on human courage!
A large number of infantry troops spread down the mountain, like a black mountain torrent.Li Yiyin was excited and nervous when he looked at the spectacular scene.Everyone comes to fight for the sake of winning!
Between the valleys, drums and shouts roared, shaking the mountains and rivers.Li Yiyin held the hilt tightly, and his knuckles turned white when he used too much force.
The soldiers who were not on duty all rested early, and even the personal soldiers standing at the central army were standing or sitting.
Guo Shao saw from the open tent and saw a soldier sitting next to the fire, holding needles and threads, silently sewing clothes on his body.
The soldier was very strong, but very young and looked just over teenage.
