On the side of the Tang Dynasty, because of the existence of Li Xuan, a later generation, it was already beginning to use relatively primitive machinery and equipment, and even when water power was used as power to produce artillery, the Ming army could still only use manual construction, even if they had a large population and more craftsmen who could collect, but it was still unrealistic to produce a large number of field artillery in a short period of time.

Craftsmen who can make cannons by hand are not so easy to cultivate!

In addition to the slow speed of hand-crafting and the difficulty of training craftsmen, this also involves the problem of the high cost of field artillery!

The field artillery of the Ming army was all cast in bronze!

And what is bronze? That's money, to put it bluntly, a bronze cannon is piled up with copper coins of the same weight, and the high cost of raw materials is self-evident.

If it weren't for the high cost of bronze-cast artillery, the Tang Dynasty would not have bothered to use iron-cast cannons, even if iron-cast cannons were inferior to bronze artillery in terms of performance.

Even so, at present, the Tang Dynasty can only use iron to make five-kilogram field cannons, and field cannons above seven kilograms still cannot be cast with iron, which has led to the Tang Dynasty directly giving up the production of seven-kilogram field cannons, and concentrating bronze resources to cast nine-kilogram field cannons.

The Tang Dynasty was limited by cost, and the large-scale use of iron-cast five-kilogram field guns and two-kilogram and three-kilogram shotguns, and the Ming army was no exception, naturally equipped with a large number of various shotguns.

The range of the shotguns that were limited to both sides was generally only more than 100 meters, so the previous artillery battles were mainly based on the field artillery of both sides, but after the Ming army saw that the field artillery shelling effect was not a big battle, they decisively ordered the infantry to charge directly, and their shotguns also rushed up with the infantry!

When the infantry of the Ming army began to march slowly, Wang Chaohong on the hill also said: "The field artillery shifts the target and concentrates its firepower to bombard the enemy infantry!" ”

After transferring firepower, more than 20 field guns began to project solid shells at the many infantry phalanxes of the Ming army!

Whenever a solid bullet falls into the Ming army's array, it can always set off a bloody storm!

And when the infantry of the Ming army braved the shelling to cross a distance of 300 meters, suddenly dozens of violent explosions occurred in the array of the Ming army, and the violent explosion raised a huge amount of smoke and dust, straight into the sky!

This is the mines laid by the Datang Army, these mines are very large, although it is inconvenient to ignite, but the power makes up for all this!

The violent explosion almost completely collapsed the several Ming military formations in the explosion!

This is not close to the top of the mountain, the Ming army has already collapsed three phalanxes, and these phalanxes are all four or five hundred people in the scale of the phalanx, which adds up, but there are more than a thousand people.

Rao is the general of the Ming army in these three phalanxes tried his best to restrain the troops, but he still couldn't stop the complete collapse of these three phalanxes!

Even in the end, it caused confusion in several nearby phalanxes!

And because the terrain is not wide enough, the place that can be used for a frontal attack is so large, so this time the troops sent by the Ming army are only a dozen or so phalanxes, and now three have collapsed, and three or four have fallen into chaos, so naturally they cannot continue to attack.

Therefore, soon the sound of gold sounded in the rear, and the remaining Ming army was like a tide, coming and going quickly, and in an instant, it retreated five or six hundred meters away.

The generals of the Ming army in the rear were reorganizing these retreating phalanxes on the one hand, and on the other hand, they also sent a second wave of offensives!

There is no way, there are enough Ming troops, even if they use wheel tactics, they can continue to launch four or five waves of offensives!

This time, the Ming army still lined up the phalanx, braving the artillery fire of the Tang Army to advance, and this time they learned wisely, and realized that they sent a team of troops to search forward in advance, and then they found the mine leads hidden on the ground, and then found many mines along these leads.

Although they were ambushed by a small number of mines at about 200 meters, the casualties were much smaller than in the first wave, so they were able to continue to push forward reluctantly.

But when they entered the one hundred and fifty meters, and the shotgun artillery in front of the infantry phalanx was ready to load and fire, suddenly they saw dozens of dark muzzles on the position of the pseudo-Tang thief army in front of them!

Seeing this scene, they don't know what these are, they must be the shotguns of the pseudo-Tang thief army!

Immediately afterward, a dense cannon fire rang out!

The Ming infantry and gunners in the front row fell in rows, and they suffered heavy casualties in an instant!

At this time, the field artillery of those pseudo-Tang thieves also began to reload with scattered shells, and every cannon sound represented countless iron nails, shrapnel, etc., and the Ming soldiers who were hit, even those Ming soldiers in heavy armor in the front row could not be spared.

After being bombarded intensively, this wave of Ming troops also inevitably collapsed, and then turned around and fled!

The failure of two consecutive waves of attacks made the Ming generals in the rear extremely angry!

The field artillery of the herald ordered his own side to attack greatly, and it seems that he is desperately trying to destroy the artillery position of the puppet Tang thief army!

But after the infantry of the Ming army withdrew, the scattered guns of the Tang Army also hid back in the trenches, as for those field artillery, although they occasionally suffered casualties, but because of the protection of the ring fortifications, the casualties were not large!

The current situation is that the field artillery of the Tang Army is certainly unable to destroy the field artillery positions of the Ming Army, but the field artillery of the Ming Army is also unable to destroy the artillery positions of the Tang Army.

However, if the infantry of the Ming army were to attack, the artillery of these pseudo-Tang thief armies that had not been destroyed would be able to inflict a lot of casualties on the infantry!

The scene, all of a sudden, is at an impasse!

In the rumbling artillery, the infantry of the Ming army rested for an hour before launching the attack again, and this time, the Ming army was even more determined, and actually invested six or seven thousand troops in a small area at once, and this number of troops almost filled the battlefield.

However, the denser Ming army formation also faced heavier casualties when it was subjected to artillery shelling!

When they rushed to within 100 meters under heavy shelling, when their own shotguns were also firing to provide support, rows of musketeers suddenly appeared in the position of the puppet Tang thief army, and then began to fire intensively!

Although there were also many musketeers in the phalanx of the Ming army who began to fight back, the pseudo-Tang thief army on the opposite side was standing behind the breastwork, only showing one head, which was too small.

On the other hand, on the side of the Ming army, they didn't have any protection, and they couldn't even lie down to avoid the bullets, because then they couldn't load.

However, on the side of the Tang Army, their breastwork is actually a very special fortification, and it is even a field fortification that has accumulated countless experience!

The height of the breastwork is about two meters above the ground, but the breastwork is not just a lonely wall, the top breastwork is about 30 centimeters thick, and behind the breastwork, there is a small platform about 60 centimeters high and about 1 meter thick, this small platform is about 1.4 meters away from the top of the breastwork, and the soldiers are actually standing on this small platform to load and shoot.

These fortifications form an L-shaped fortification on the ground, the upper half is actually used for bullets and scattershots, and the base of the lower half is used to raise and defend against solid bullets!

Behind the breastwork, there was a trench about one meter deep, and this half-meter-deep trench was the last means of defense after the base of the breastwork was destroyed by enemy artillery!

And at every distance in the breastwork, there is a small gap, which is used to house the shotguns!

The depth of the breastwork will also be connected by several communication trenches, and will be connected to the second and third breastwork trench defense systems in the rear.

And in the rear, as a rule, there will also be artillery positions protected by ring fortifications.

If it is a defense in the mountains, then the first, second, third, or even more fortifications and field artillery positions can be fired at the same time, and the defensive fire is extremely fierce.

This kind of field fortification was formed by a group of staff officers of the Tang Army who studied it for several years!

It is quite suitable for the current large-scale use of muskets and artillery in the Tang Army, in order to allow the troops to quickly dig field fortifications in the field, the soldiers of the Tang Army also got a new piece of equipment: "Wooden handle shovel!" And the units have also begun to strengthen the applicator units.

Again, this is the first large-scale combat of this defense system!

And this set of fortifications, but also Wang Chaohong's greatest confidence, relatively speaking, the mines planted in advance did not play a big role, after all, these mines are too defective, need the fuse ignition, as long as people find the fuse, they do not find the mines, directly cut the fire rope is enough to make those mines planted in advance useless.

Seeing that the shooting effect of his own musket was not good, and even the effect of the shotgun was not very large, a general of the Ming army who led the front row just shouted, commanding the troops to rush forward directly!

In his opinion, the puppet Tang thief army is a hundred meters ahead, and what stands in front of them is just a small wall two meters high, as long as they can rush through, then they can engage in hand-to-hand combat with the other party, and then use their absolute strength advantage to completely defeat the other party!

But when they rushed to about thirty meters, the small low wall on the opposite side suddenly flew out of small black dots, and experienced Ming soldiers could recognize it at a glance!

Immediately, someone shouted in horror: "It's not good, this is a flowering bomb, get out of the way!" ”
