Chongzhen Daming: Starting from Coal Mountain

Chapter 84 Calibration Shooting
Bai Yintu and Aobai also hurried over after receiving the report.

After listening to Gao Di's explanation, Bai Yintu didn't say anything, but Aobai didn't believe anything he said.

"Impossible, impossible, this is absolutely impossible!" Obai looked disbelieving and contemptuous, "The tiger squatting cannons of the Ming army are all huddled inside their formation, and there is a slope protection in the middle. You said the tiger squatting cannons I believe that the lead can go over the slope protection, because the tiger squatting cannon was originally fired into the sky, which is the same as the long-distance projectile of the Mongols, but you explained that the army's tiger squatting cannon can hit our fort through the slope protection , then you are just playing us like monkeys, do you think I will believe it?"

"No, Master Oboi, how dare I play with you?" Gao Di was so anxious that he was about to cry, "What I said is true, the Ming army's tiger crouching cannon really looks like it has eyes, and it's terrifyingly accurate. "

"It's impossible to grow eyes." Aobai said angrily.

"Can you see the position of the Ming army through the slope protection?"

"Ah, this..." Gaudi was speechless, because he couldn't figure it out until now.

In the end, he had no other choice, Gaodi pointed to the dozens of corpses that were beaten to death by the tigers of the Ming army and lined up in a row, and said, "But Mr. Oboi, these dozens of corpses must not be fake, right?"

"Who knows how they died?" Obai still didn't believe it.

"Let your people go to the front to build the fort now. I want to see how the Ming army's tiger squatting cannons hit your heads with shells across the slope."

"Master Oboi." Gao Di became anxious immediately.

"Aren't you letting us die in vain?"

Seeing that Aobai was unmoved, Gaodi could only ask for a picture of Bai Yintu.

"Master Baiyintu, what I said is true, it is true."

"Gao Di, I believe in you." Bai Yintu's eyes flashed, and he said, "But what Aobai said has some truths, we must know how the Ming army fought against you before we can think of a way to deal with it, right? ?”

Gao Di was desperate, and these slaves didn't treat them as human beings.

However, people have to bow their heads under the roof mast. Who made them surrender now?
Immediately, Gaodi ordered his descendants to divide into fifteen teams and go to repair the front fort again.

Of course, the soldiers who surrendered were very dissatisfied, but faced with Jiannu's flashing butcher knife, they could only grit their teeth and move forward, while praying in their hearts that the Ming army would never shoot again, or that they would not be able to hit them if they did.

However, the ancestors have obviously abandoned these descendants who have forgotten their ancestors.

Just after the Jiang army entered the unrepaired fort, the Ming army's tiger squatting gun rang again.

Accompanied by the loud bang of "Boom, Boom, Boom, Boom, Boom, Boom, Boom, Boom, Boom, Boom," and thousands of semi-double lead fell on the construction site like a torrential rain, and the Jiangjun fell down in an instant.

"Really!" Seeing this scene, Obai finally believed it.

"Gao Di, quickly withdraw the people." Bai Yintu said quickly.

Gaodi hurriedly asked his family Ding Mingjin to withdraw all the surrendered troops.

However, at this moment, dozens of his troops were killed or injured.

"This is really evil." Obai finally believed Gao Di's words.

"The tiger-squatting cannon of the Ming army can hit even people they can't see?"

Gao Di said with a bitter face: "My lords, the fort really cannot be repaired."

"No, the fort still needs to be repaired." Bai Yintu thought for a while, and then said, "But it can be farther away from the Ming army's gun emplacement. The Fran cannons in China can hit [-] or even [-] paces, so you can build the fort at [-] paces, so that the Ming army can only stare blankly."

"Hey!" Gaudi had no choice but to obey.

……

Jiannu moved the fort 300 steps away and quickly reported it to Chongzhen.

Chongzhen brought his two sons to the front again for close observation.

"Father, there seems to be nothing we can do now." Zhu Cijiong said a little depressed, "The tiger squatting cannon can only shoot 300 steps, and it's out of reach."

"Your Majesty, otherwise, attack."

Tian Xiong once again took the initiative to ask for a counterattack.

"No, you can't attack!" Chongzhen once again sternly refused.

Now is the critical stage of building up confidence and morale. Tian Xiong, the town soldier, or Xia Zhen's ten town soldiers have managed to accumulate a little confidence, so they can't squander it at will.

Jiannu hasn't moved south in a big way yet.

The real test will be when Jiannu goes south in a big way.

"But Your Majesty, we can't just sit and watch Jianu build the fort?" Tian Xiong said anxiously, "When Jianu builds the fort, we won't be able to fight back."

"No." Chongzhen said: "Jiannu repairing the fort five hundred steps away is simply a blind man lighting a lamp."

"Blind man lighting a lamp?" Tian Xiong, Huang Degong, Zhu Cihong and Zhu Cijiong all looked blank.

"It means it's pure waste." Chongzhen explained with a smile, "Blind people can't see anyway when they light a lamp."

Zhu Cijiong said: "Father is saying that even if Jiannu builds the fort, it won't be able to hit us?"

"It's still possible to hit it, but it can only hit the slope protection in front." Chongzhen smiled and said, "They can't hit the blunderbuss platform behind the slope protection."

Huang Degong, Tian Xiong and others still looked at a loss.

Chongzhen knelt down and drew a sketch on the ground.

In fact, it is a simple schematic diagram of a ballistic curve.

"Look, this is our gun platform. There is a slope protection in front of each gun platform, and the height of the slope protection is only 2 feet higher than the fence of the gun platform."

"The distance between the two is 30 steps."

"The fort built by Jiannu is 500 paces away."

"If Jiannu's Fran cannon can hit our blunderbuss, at least half of the fence in the front must be seen, at least a height of 2 and a half feet, less than 2 feet."

"The height of 4 feet is multiplied by 17 times, and it is 68 feet."

"That is to say, Jiannu had to build a 6-foot-8-foot fort to be able to see the blunderbuss, so that their shells could cross the slope and hit the front of the blunderbuss."

If you miss the front, it's pointless.

Because the defenders of the gun platform usually guard the front of the gun platform.

"What? A fort of 6 feet and 8 feet?" Huang Degong, Tian Xiong and others looked at each other in blank dismay.

Are you kidding, 6 feet and 8 feet can't be as high as the city wall of Nanjing?How big is that project?Even if Jiannu spends a year here, he may not be able to build the fort.

Zhu Cijiong asked: "That is to say, if it is less than 6 feet and 8 feet tall, it is the same as not being cultivated?"

"Yes, the same." Chongzhen laughed, "If the fort cannot be repaired to a height of 6 feet and 8 feet, then there is no difference between mounting the cannon on the fort or on the ground. The back of the tower, but that doesn't make any sense, because the defenders of the tower can hide in the front of the tower."

Zhu Cijiong said: "Unless they can imitate our tiger squat..."

"Hush!" Chongzhen hurriedly made a silent gesture to Zhu Cijiong.

This kid Zhu Cijiong has a real brain, so he started to infer other things from one instance.

From the "guided shooting" of the tiger squatting cannon, he had already imagined that the Franc machine gun and even the Hongyi cannon could also be used for guided shooting. Zhu Cihong and Huang Degong had never thought of it.

No one even thought of it in the whole era,

The Hongyi Cannon can also shoot in a curved line.

So this must be kept secret, strictly kept secret.

It's not that they don't believe in Huang Degong and Tian Xiong.

But it's just a thin layer of window paper.

Once this layer of window paper is pierced, with the quality of "good at learning" shown by the last two senior leaders of Jiannu, they will definitely learn this magic weapon quickly and popularize it.

If Jiannu really discovered the beauty of it, there would soon be observers in the artillery units of the Eight Banners Han Army, and there would definitely be artillery staff officers who specialize in ballistic calculations.

Maybe Jianu's mathematics will advance by leaps and bounds.

This is what Chongzhen is unwilling to see anyway.

It is already difficult enough for Jiannu to have a powerful Hongyi cannon unit. If Jiannu's Hongyi cannon unit understands the essence of guided shooting and evolves a real infantry artillery support, supplemented by Eight Banners soldiers The powerful field killing and the Mongolian cavalry's riding and shooting, so the Ming Dynasty still played a ball?

Therefore, this layer of window paper must not be easily pierced.

Guided shooting can only be limited to the range of the tiger squatting gun!

At least until the artillery of the Ming Dynasty has not formed a crushing advantage over the Jiannu artillery, the concept of guided shooting must not be easily introduced to the Flang machine gun and Hongyi artillery units, even if it is mentioned.

Chongzhen stopped Zhu Cijiong, and said to Tian Xiong: "Tian Zongbing, while Jiannu is busy building the fort, let's hurry up and measure more shooting parameters, and give Jiannu a calibration shot."

Tian Xiong asked with a blank face: "My lord, what is calibration shooting?"

Chongzhen drew a few more circles on the map, pointed to the circles and said, "Look, Zongbing Tian, ​​these are about fifty blunderbuss platforms in your town. Originally, Jiannu attacked any blunderbuss platform on the outer layer. At that time, only the four adjacent blunderbusses could provide artillery support, but in fact, there are eight other blunderbusses within [-] paces.”

"The tiger crouching cannons of these eight blunderbuss can actually provide artillery support."

"If a total of 12 blunderbusses and 24 tiger squat guns can measure the shooting parameters in advance,"

"Then Jiannu will attack a certain blunderbuss platform. When the defenders of this blunderbuss platform retreat, the 12 tiger squat cannons of the 24 adjacent blunderbuss platforms can shoot at it!"

"Ah this?" Huang Degong and Tian Xiong looked awe-inspiring.

Each blunderbuss platform originally had only 2 tiger crouching cannons.

How can it become 26 tiger squatting cannons?

Could it be that this is the old legend of "Scattering beans into soldiers"?

Chongzhen warned again: "But the parameters must be measured accurately.

"If the measurement is inaccurate or goes off track, it's not a big deal to waste ammunition, but it's a bad thing if the lead falls on Pao Ze's head."

"And after the parameter measurement is completed, you must make a simple record and name each point sequentially with a number. For example, point No. [-] means that the first set of parameters is played, and it corresponds to the No. [-] gun platform."

Tian Xiong seemed to understand but not understand.

Chongzhen sighed when he saw this.

He has tried to simplify it as much as possible, but Tian Xiong still doesn't understand.

But it's no wonder that this is much more difficult than guided shooting.

To put it bluntly, guided shooting is to let the cannon grow eyes, and calibration shooting is equivalent to giving the cannon a program.

It seems that without a high-quality artillery unit, large-scale calibration shooting is not realistic, so you can only work harder to measure the shooting parameters yourself.
