"Long live the lord, long live the lord!"

Chongzhen was accepting Wanbang in a dream when he was suddenly woken up by a voice.

sat up, but found that it was Wang Chengen: "Long live Lord, Jing Nanbo sent someone to report that there is a new movement in Jiannu." ”

"Got it." Chongzhen stroked his beard, and woke up Zhu Cihong and Zhu Cijiong, who were still sleeping soundly, and then came to Huang Dejun's admiral line without having breakfast.

"Holy Lord, it seems that Jiannu wants to build a high platform."

Huang Degong paid a great salute and went on to say: "I don't know what to do with it." ”

"Let's go ahead and have a look." Chongzhen immediately took Huang Degong and his two sons, surrounded by several eunuchs and a team of Yiding, to the northernmost part of the defense line.

This time I didn't ride a sailor ship, I rode a horse.

After a while, a group of 100 people arrived at the ground.

"Knock to the Holy One." Tian Xiong stepped forward to pay respects.

"Aiqing is exempt." Chongzhen waved his hand and said, "Tell me about the situation." ”

Tian Xiong responded, and said: "Today, before the sky is bright, a team of troops will come, there must be two or three thousand people, and they brought pickaxes and other tools, and after they came, they built a platform behind the slope protection, and now they are all several feet high." ”

Chongzhen looked up, but unfortunately there was a slope protection in the middle, and he couldn't see anything.

At that moment, Chongzhen got off the platform, and followed the narrow passage reserved in the middle of the sharp wooden stakes and bamboo thorns to the back of the slope, where the Ming army sentry had set up a ladder specifically for observation.

Seeing Chongzhen and his entourage coming, the sentry hurriedly came down and saluted.

patted the sentry on the shoulder, and Chongzhen climbed the ladder directly.

From the bottom of the ditch to the top of the slope protection, the total height is more than one zhang, Chongzhen climbed up twice, looked over the top of the slope protection and looked out, only to see thousands of Jiannu divided into more than a dozen groups, digging and ramming on the wilderness in front of the oblique, and the nearest earthen platform was not even more than thirty steps away.

Huang Degong, Tian Xiong, Zhu Cihong, and Zhu Cijiong also climbed up from other ladders.

"Father, what does Jiannu want to do?" Zhu Cijiong asked, "Follow Yuan Shao's example in the Battle of Guandu, build a high platform and condescendingly fire arrows at our platform?" ”

"It's supposed to be a cannon." Zhu Cihong corrected.

"After all, the bow and arrow can't shoot far, and the power is not great."

"Well, Hong'er is right." Chongzhen nodded and said, "Jiannu probably wants to build a row of forts, and then set up a Franc machine gun to bombard our fort condescendingly." ”

"That's a bit of a problem." Huang Degong frowned and said, "Jiannu repaired the fort, and the slope protection became an ornament, and our fort was directly exposed to the muzzle of Jiannu's gun." ”

Tian Xiong suddenly said: "Shengshang, why don't you fight back and kill this group of Jiannu?" ”

Chongzhen glanced back at Tian Xiong with some surprise, it seems that the two victories during the day and night yesterday have given Tian Xiong a lot of encouragement, and he actually has the courage to take the initiative to go out to the camp to fight.

However, Chongzhen also knows very well that Tian Xiong, a town soldier, does not have this strength at all.

Therefore, we must be careful to protect the confidence of Tian Xiong and his town soldiers, and we must not easily waste the battle.

"Fighting back is to fight back, but you don't need people to go." Chongzhen smiled slightly, "Fight back with the Tiger Squat Cannon." ”

"Huh? Tiger squat cannon counterattack? Huang Degong, Tian Xiong and Zhu Cihong's little brothers were a little stunned when they heard this.

Zhu Cijiong was even more puzzled and asked: "Father, there is a slope protection in the way, how can the tiger squat cannon hit?" ”

Chongzhen smiled and said: "Today, my father will personally teach you a lesson, how to make our tiger squat cannon grow a pair of sharp eyes, and guide shooting through the slope!" ”

Back in the platform, Chongzhen was not in a hurry to go to class.

Instead, he asked Tian Xiong to call all the gunners from the nearby gunners.

He also asked Gao Qiqian to find a long wooden board one inch thick and cut it into dozens of small pieces.

In the Ming generation, due to the lack of manufacturing technology, the accuracy of artillery was not very high, so there was no concept of guided shooting, and they all relied on the experience of gunners to hit great luck.

If you're lucky, let the enemy eat.

If you're unlucky, you'll eat at your own family.

But in fact, Ming Dynasty artillery could also guide fire.

The howitzers of later generations are to first measure the shooting Zhuyuan, and then carry out covered shelling according to the measured shooting Zhuyuan, the Tiger Squat Cannon, the Buddha Lang Machine Gun and the Hongyi Cannon of the Ming Dynasty can be measured first, but the accuracy is poor, and then it can not be uniformly measured, but each gun must be measured separately.

Up to two cannons are placed together for measurement.

"Let me start with a few concepts."

"This little piece of wood is about an inch thick, and it's a scale."

Chongzhen picked up a small cut wooden block and showed it to everyone.

Then he made a gesture to the left and raised another finger.

"The meaning of this gesture is to shoot one scale to the left."

"That means you have to move the tail of the Tiger Squat Cannon in the opposite direction, that is, to the right by an inch, can you understand?"

Most of the gunners nodded to indicate that they could understand, so Chongzhen didn't say more, and let the gunners who had already understood go back to the companions who didn't understand the church.

Chongzhen then made three more gestures to the right, up, and down.

"These three gestures mean that the shooting boundary adjusts the corresponding scale to the right, up or down, one finger means adjusting one scale, and two fingers two scales."

"Left-right adjustment only requires moving the tail of the gun."

"Adjust the firing angle up and down to raise or lower the tail of the gun."

"Finally, when the calibration is completed, this gesture is made."

After speaking, Chongzhen stretched out his left and right hands at the same time and gave a thumbs up.

Most of the gunners understood, it doesn't sound difficult to understand.

Chongzhen called out one of the more than a hundred gunners at random and asked, "What's your name?" ”

"Back to the saint, the villain is big, and the big one is called Niu Manzhi." The artilleryman was flushed with excitement.

Chongzhen smiled: "Niu Da, right, now I will provide you with the parameters, and you can adjust the angle of shot." ”

"Yes!" Niu Da responded, and immediately walked to the back of a tiger squat and squatted down.

Chongzhen put his fingers together and pointed to the ground, clicked twice, and then raised a finger towards Niu Da.

Niu Da thought about it for a while, and immediately grabbed a small wooden block and put it on the tail of the tiger squat cannon, and then fixed it, correct!

Chongzhen then reported three sets of parameters, which were to adjust the parameters to the left, to the right and up, and as a result, Niu Dadu made correct adjustments to the firing range and firing angle of the tiger squat cannon.

"That's it." Chongzhen said happily.

"Go back now, and each of you will send an observer to hide behind the slope guard and observe."

"Then the Tiger Squat Cannon carried out multiple test firings, and the test firing should be consistent with the charge when the official firing was fired, otherwise the test firing would be equivalent to no test firing." Speaking of this, Chongzhen suddenly remembered a question, and asked Niu Da again, "By the way, Niu Da, do you fill a certain amount of gunpowder every time you fire a cannon?" ”

"Yes." Niu Da hurriedly said, "There is a measuring bucket, and there are three scales in the measuring bucket, which are full, half-full, and half-full, and the firing range is about 300 steps, 200 steps, and 100 steps when firing the cannon. ”

[Note: Ming Dynasty 1 step = 5 feet = 1.6 meters]

"Okay, all the charges will be full in the future." Chongzhen Road.

"The loading is uniformly combined with 50 half-tael lead or stone bullets."

"Each gun is tested first, after the test firing is completed, the observer observes the landing point of the shell, and after the observer finds the landing point of the shell, he adjusts the parameters according to the distance between the landing point and the target and the azimuth, until the final shell can accurately hit the target, and finally calibrates the parameters!"

"Do you understand?"

"Got it!"

……

Gaudi was sitting overseer.

"Master, eat watermelon."

A family member came to Gaudí with a watermelon as big as a bowl.

"Where did you find the watermelon?" Gao Di's eyes lit up, and it was really enjoyable to eat a piece of watermelon on this hot day.

Jia Ding said: "When I went out to patrol yesterday, I found a wild watermelon vine, thinking that maybe it would bear fruit, and I found it again today, but unfortunately I had such a watermelon." ”

"Cut, cut." Gaudí couldn't wait.

The family put the watermelon on the ground, and then pulled out a waist knife and cut it.

After cutting it, I found that it was not ripe, and the melon pulp was only slightly red.

Gao Di didn't dislike it at all, it would be nice to have watermelon to eat.

Just as he was eating, Leng Buding heard a "boom" sound in front of him.

"Cannons? Where's the gunnery? Gaudi was taken aback and hurriedly stood up.

"It seems to be the Ming army's gun." Jia Ding pointed ahead, "It should be." ”

"Oh, that's fine." Gaudi sat down on the saddle that served as a stool.

"There is a slope protection in the middle, and the Ming gunners can't see it at all, so they fight blindly."

As if to verify Gaudí's words, as soon as he finished speaking, a puff of smoke and dust suddenly rose from the wasteland thirty paces in front of him, and mud and sand flew with broken grass.

"Look!" Gao Xiao smiled, "Isn't this just a blind fight?" ”

"The Ming army probably doesn't have any tricks." Jia Ding echoed with a smile, "When we build the fort and mount the Franc machine gun on the fort, the Ming army can only surrender obediently." ”

"Yes." Gao Di thought so, "The Ming army has only one way to surrender." ”

While the two were talking, there was another bang in the direction of the Ming army in front of them.

"Coming back?" Gao Di said angrily, "What do you say you are doing with all this effort?" ”

Jia Ding pointed to Gao Di's right and said, "Master, this time it seems to be closer." ”

"What's closer?" Gao Di turned his head blankly, and then saw at a glance that less than ten paces away on the right side, there was already an extra pit of the size of a bowl, and it was steaming outward.

What's going on? Was it the tiger squat artillery of the Ming army?

After a while, there was another bang in the direction of the Ming army's platform in front of him.

Immediately Gaudi heard a scream, as if something was passing over his head.

The next moment, a scream suddenly sounded behind him, and when he looked back, Gao Di was extremely surprised to see that dozens of soldiers who were busy building the fort had already lay down, and the rest had scattered and fled.

What's going on? What's going on? Gao Di was stunned.

Is it difficult for the Ming army's tiger squat cannon to grow eyes? How can you hit it so accurately?
