"With this kind of fighting power, he dares to attack our Da San Pass. It seems that the intruders were really killed by Guo Xingye last year, and many of his elite soldiers and generals were lost.

Alas, it's a pity. If Governor Sun hadn't been forced to stay in this Shaanxi land by His Majesty, knowing that it couldn't be defended instead of defending it, he would never have suffered such a vicious attack if the people were not in a province where everyone wanted to be a thief..."

Standing on the wall of Dashan Pass, Cao Bianjiao, with a stern look on his face, put down the telescope to observe the enemy's situation, and couldn't help but think so in his heart.

Of course, some of his thoughts were a bit rebellious, but he only dared to think about them in his mind, and would never speak them out, not even whispering to himself.

He was actually Dashanguan who had just arrived secretly these two days, but did not make any announcement. The task given to him by Zhu Shuren was to take the opportunity to eliminate more invaders who dared to invade, inflict pain on the enemy, and completely stop them from thinking about going south.

At the same time, it also allows the prince and his father-in-law who are about to return to Beijing to report one or two more good news about the efforts of the Huguang Army to fight against thieves, so that His Majesty can feel at ease. I firmly believe that the Huguang Army will always use both hands in its own way, and both hands must be hard to keep up.

The fighting of the Chuang army did not encourage the invaders to respect themselves.

Cao Bianjiao knew very well that if he wanted to hurt his enemy, he had to give him some hope first, and he could not attack him hard all at once. Therefore, during the first one or two days of defense, he hid a lot of heavy firearms.

It was only at this moment that Yuan Zongdi on the opposite side seemed to be trying to dig holes in the city wall to bury gunpowder and blast it. Only then did Cao Bianjiao become serious and realized that he had to deal with it well.

Cao Bianjiao is experienced in fighting. After fighting with the bandits for more than ten years, he certainly knows the tricks and routines of the bandits.

Li Zicheng used the trick of digging holes and burying explosives to blow up the city wall in Kaifeng last year, but the wall in Kaifeng was too thick, so he failed. Later, when Zhang Xianzhong conquered Chengdu, he used the same trick, but it was successful that time.

The famous generals in the army naturally gave the highest priority to the level of embankment in this hand. When he saw the wooden donkey digging the city frantically, Cao Bianjiao guessed 70% to 80% of it.

But he knew that there could not be coffins filled with gunpowder hidden under the first batch of wooden donkeys for digging the city - because the first batch of wooden donkeys for digging the city were so large, there were dozens of them, and the invading army could not have so much gunpowder.

There are several large coffins containing more than a thousand kilograms of gunpowder each hidden under each wooden donkey.

And even if you want to hide it, given the size of the city-digging wooden donkey, if so many coffins are crammed into it, it will not be able to accommodate a few carts and digging soldiers, and the excavation progress will be very slow.

Therefore, the most classic tactic of the bandits is to not put any gunpowder in the first batch of wooden donkeys, and only focus on digging the wall. Based on the actual combat progress, confirm which points are dug fastest and have the loosest soil, and then use the second batch of wooden donkeys to dig the walls.

Donkeys specialize in transporting gunpowder, focusing on burying and bombing the easiest points to break through.

Cao Bianjiao knew this very well, so he calmly allowed the first batch of wooden donkeys to approach the city wall, allowing the enemy to dig in without using heavy firearms to stop them.

It was not until after a bloody battle for half a day, towards the evening of the same day, that Yuan Zongdi sent in a large number of wooden donkey carts as substitutes that Cao Bianjiao accurately judged that the drama was about to come on stage.

Among these wooden donkeys, there must be coffins full of gunpowder!

"Prepare all the Folang machines, including the only two Hongyi cannons, and replace them with new ammunition with bullet supports. The Qianjin Folang machine will use charged ammunition, and aim them at the reinforcements of the city-digging wooden donkeys.

!The cavalry is also equipped and ready to follow my general to open the door and charge to kill at any time!"

The Ming army's artillery immediately followed the order and loaded all the artillery pieces with new ammunition with bullet supports——

The technology of adding bullet holders to artillery shells was invented by Zhu Shuren as early as the second half of last year. Its first actual combat performance was on the Chenxian battlefield in August of that year. At that time, only shrapnel shells were equipped with bullet holders.

It also took advantage of Chuang Jun's ignorance of the existence of this new weapon to solve the problem of "the shotgun can't reach far", allowing the shotgun to fly a hundred or two hundred steps under the cohesive restraint of the bullet holder before breaking free from the restraint under air resistance and starting to

They dispersed. In the end, they succeeded in beating Li Zicheng into a pock-marked face and a one-eyed dragon, and also killed Li Guo and shot a large group of Li Zicheng's personal guards.

After returning to Huguang last fall, Zhu Shuren asked Fang Yizhi and Song Yingxing to continue improving along this technology tree. They soon learned by analogy and tried adding bullet holders to all kinds of artillery shells, including solid bullets, as well as the latest technology just developed this year.

The original first generation flower bomb.

These tasks were completed last winter and this spring. However, during the final battle against Zhang Xianzhong, these weapons were of little use. During the siege, it was enough to directly blast the solid bullets, and there was no point in adding bullet holders, so they have not been recovered.

I just got my first show today when I got a chance to practice.

The newly developed explosive shells currently developed by Zhu Shuren's army are still relatively primitive. They use a delayed fuze that ignites the fuse before firing, which is somewhat dangerous. If the firing action cannot be completed within five to ten seconds after ignition, the shell may be

The kind that self-destructs directly in the barrel.

[Recommended, it’s really easy to use, download it here and you can try it soon.]

The specific number of seconds of delay is related to the length of the fuse of the explosive bomb and the burning speed. Changes in climate and humidity will also affect the burning speed of the fuse and cannot be precisely controlled. Therefore, for the sake of your own safety in actual combat, you must leave some margin and would rather fall to the ground.

It will explode after a few seconds, but it shouldn't be too stuck.

Otherwise, just like those players in the chicken game who pursue air explosions too much, they may directly explode themselves.

Even if the firing time is well controlled, if the shell rotates too fast during flight and the air friction is too large, there is a certain probability that the fuse will be blown out by wind resistance, causing it to become a dud when it lands, or require other ignition to activate.

It is normal for the dud rate of explosive shells in this era to reach half. After adding the bullet holder, the spin of the shell during flight will decrease to a certain extent, and the probability of wind resistance blowing out the fuse will also be reduced, but the self-stability of the shell will also be reduced.

will fall,

Generally speaking, the improvement in accuracy brought by the bullet holder and the decrease in accuracy caused by the reduced spin of the shell can basically be offset. If it is used to fire solid bullets, it is a bit redundant to bring or without the bullet holder. For explosive bullets, for this reason

The dud rate is reduced, and it is more cost-effective to carry a bullet holder.

In addition, when attacking sloping armor, the version with a bullet holder to reduce spin can reduce the probability of ricochet and improve the armor-piercing effect. The version without a bullet holder has strong spin and is easy to ricochet, and the killing efficiency of rebound personnel will also be reduced.

promote.

If you want to hit human targets and pursue ricocheting more kills, then don't bring a bullet holder. If you want to penetrate armor and hit a wall, bring a bullet holder. These data have been rigorously tested by Zhu Shuren's army with live ammunition, and they have summed up considerable experience.

Actual verification.

It is precisely because this kind of thing is not much improved compared to the previous generation of weapons, so the technical difficulty is not great, so it can be built so easily.

…

Under Yuan Zongdi, the person responsible for commanding the first line of excavation and blasting was a brave general named Lan Yingcheng. Lan Yingcheng was also a cold-blooded and cruel man. In the past two days, he had already killed thousands of cannon fodder, old and weak people.

With his own life, he used his life to get out of this bloody road in Guanxia.

At this moment, with the explosive truck still about 200 steps away from the city wall, the Ming army's heavy artillery on the wall suddenly opened fire intensively, which instantly shocked Lan Yingcheng.

"Boom boom boom——"

"Whizzing--"

The shells screamed across the sky, and those with sharp eyes during flight could even see that these shells scattered some debris in mid-air.

It was obvious that the shell's holder had been exploded by the high chamber pressure when it was discharged from the chamber. It was only forced to fly a hundred steps by inertia, and then was pushed by the wind resistance and fell off the projectile body.

Although the fragments of the bullet holder were made of hard wood, people who hit them were still killed or injured. Several soldiers of the invasion who were not hit in the vital points fell to the ground and howled in an instant, and the morale of the soldiers nearby was inevitably damaged.

"Crack--Crack--" At least two-thirds of the dozen or so military artillery shells hit the ground, plowing a bloody path, but two or three of them hit the huge wooden donkey cart that dug the city.

The texture of the wooden donkey cart is far sturdier than that of a warship. Because warships also have to consider their seaworthiness, they are made of wood cut into planks. The wooden donkey cart does not consider these, and is made of logs directly from big trees.

If the tree is one foot thick, the thickness of the wooden donkey cart can naturally reach one foot. The thin joints between the wood and the wood can be filled with mud.

The first batch of artillery shells that hit were all fired by the rapid-fire Folang machine. The cannon itself weighed no more than three hundred kilograms, and the projectiles were only one or two kilograms. After breaking some wooden beams, they did not penetrate into the car body and ricocheted directly.

It bounced off.

The officers of the intruder army broke out in a cold sweat, and Lan Yingcheng, who was supervising the battle from behind, was also the fastest to respond. He immediately started urging the cars to accelerate at the top of their lungs:

"Tell them to push hard! One or two shots from the army's artillery may not penetrate the top of the wooden donkey's slope! It will be safer to push it a hundred steps below the city wall! That way the army's artillery will not be able to shoot down the blind spot!"

The veteran generals in the army have rich battlefield experience. They all know that it is difficult for artillery to fire downwards and the shells are easy to roll out.

The generals of the Chuang Army who participated in the siege of Chen County last year had seen that the Shen Jiajun's Folang machine could shoot downwards, but the angle of the downward shooting was not very large. The generals of the Chuang Army were uneducated and did not understand scientific knowledge.

, I don’t know that this is caused by the bullet holder, which increases the friction when the projectile is placed in the barrel.

As for the Dashanguan Wall in front of us, the front that can be attacked is actually narrower. It is in a narrow valley in the Qinling Mountains, so it is difficult to deploy cross fire on the left and right sides. There is no enemy platform protruding from the wall, so it is impossible to perfectly reproduce Chen's attack.

The deployment of "the enemy tower on the left shoots down the enemy on the right, and the enemy tower on the right shoots down the enemy on the left" during the county defense battle.

In addition, Yuan Zongdi's troops were the only troops among the troops that had never participated in the siege of Chen County. At that time, they were raising food in Shangqiu, Guide Prefecture. Lan Yingcheng lacked intuitive experience, so he made such a judgment.

No problem either.

The invading army and the soldiers digging into the city pushed hard, trying to get into the blind spot under the city wall as soon as possible.

Unfortunately, this kind of operation obviously underestimates the maximum shooting depression angle that the Folang machine can achieve with the addition of a bullet support. The Folang machine manufactured by Shen Jiajun can even lower the muzzle by more than thirty degrees at its lowest point.

They all ensured that the cannonballs tied with wooden supports would not roll out of the barrel.

The height of the city wall is less than ten steps. A simple trigonometric calculation can show that as long as the enemy does not push the wooden donkey cart within thirty steps of the base of the city wall, the Folang machine can attack the top with a downward attack.

Moreover, the closer the distance is, the more perpendicular the angle between it and the armor on the slope of the donkey cart when shooting from above, and the less likely it is to ricochet.

Anyone who has played artillery games such as "World of Tanks" and "World of Warships" can understand this common sense.

Lan Yingcheng let the soldiers of the intruder army rush forward for a few more minutes despite the firepower. He even sent a large number of soldiers from the old battalion to rush forward at the cost of their own lives. They pushed the car forward with shields from outside the car body -

Under normal circumstances, the pushers of wooden donkey carts hide in the cart and push it under the cover of armor to avoid the impact of falling rocks. In this situation of fighting for time, in order to prevent long nights and dreams, even human lives are at risk.

I don’t care anymore, if there are a few more people pushing me, if I can’t stand in the car, I will stand on the sides and back of the car, exposing myself and push me hard.

The army's musketry team also had sharp firepower. Seeing so many live targets, of course they fired wildly at them. The iron slag and iron nail crushing lead bullets that originally had no effect on thick wooden armor now penetrated the flesh and pushed rows of them.

The car was beaten into a bloody gourd by the soldiers. However, the car moved slowly and could not push a step every second, making it a living target.

In a very short period of time, hundreds of intruders who were pushing carts outside were directly lined up and shot. Some soldiers had already retreated timidly. However, Lan Yingcheng personally supervised the battle, risking his own life and leading the old battalion guards to attack and kill the deserters wildly.

"Those who take one step back will die! You won't be afraid if you rush to the base of the wall despite the artillery fire from the army! We can't let the brothers in front die in vain!"

Lan Yingcheng killed more than a hundred of his own people before he could completely suppress the situation with bloody and terrifying intimidation.

However, all his efforts were destined to be in vain. When the wooden donkey cart filled with gunpowder approached less than a hundred steps below the city wall, the army's artillery had already fired its third round. After calibrating, aiming, and correcting the trajectory, it accurately and effectively penetrated the city wall.

A shot finally appeared frequently.

A large iron ball weighing several kilograms, with less than a kilogram of black powder charge inside (early cannonballs should not be charged too much, and the shell should be thicker, for fear of self-explosion when coming out of the barrel), one after another penetrated the wooden donkeys that dug the city.

of strong top armor.

The iron ball bounced inside the wooden donkey cart, instantly stirring up a shower of blood and flesh. In such a densely populated confined space, at least seven or eight people were killed in an instant.
