The clouds were thick, and the sky was drowsy, and it seemed that it was about to rain at any moment, but it was not raining for a long time.

On the ground, a huge Jin army camp towered there like a giant beast, and the Song army soldiers who looked like ants rushed to kill, and all kinds of siege equipment were densely packed, and they launched a fierce attack around the Jin army camp.

In the era of cold weapons, the form of war is very simple and direct, nothing more than three kinds, one is the main battle, the two sides have a war letter, set up a large array to kill; the second is to set up ambushes to defeat the enemy by surprise; Third, there is a huge disparity in strength between the enemy and us, with one side defending the walled city and the other attacking.

On the battlefield, the last thing the famous generals are willing to fight is siege warfare and siege warfare.

In this era, there are no missile strikes, no aircraft bombing, no tanks to open the way, and no heavy artillery bombardment, everything is mainly cold weapons, and if you want to break through a well-defended camp, it is difficult to climb to the sky, and you often have to pay a heavy price to completely break through.

Sometimes they paid a heavy price, but they did not gain anything, but under the enemy's counter-charge, they were devastated.

Siege warfare, or siege warfare, is what Zhang Jun is most reluctant to fight!

It's just that he has to fight at this moment, because the Jin army is like a turtle with a shrunken head, staying in the camp, just not moving, so that the Song army is helpless. If it goes on for a long time, the food consumption will be serious, and the teachers and veterans will be lacking, and there will be no doubt about defeat.

At this moment, it can only be mainly attacking, constantly dying, paving the way with corpses, and breaking through the Jin army.

One by one, the soldiers of the Song army rushed forward to kill, some holding shields. Resisting the sharp arrows that came from them, some of them pushed the cart forward, in front of the cart. At the top, there are simple partitions on the left and right, which can resist the rain of arrows coming from the shot.

Before the cart is pushed into the trench, the sand from the cart is poured in to fill the trench so that the rear troops can attack smoothly.

The defending Jin army used precision shooting to shoot the Song army. The feathers of the arrows are not dense, but they are better than the precision. And in the rear of the battalion, trebuchets fired stone projectiles. Bombarding the attacking Song army.

"Kill!"

"Boom!"

The soldiers of the Song army rushed to kill, their eyes were blood-red, murderous, and they kept pressing forward. Storm the Jin military camp.

All kinds of siege equipment. They appeared one after another, or hit the gate of the wall, or the fireballs flew wildly, smashing into the Jin military camp, or the arrows rained like flying, the bed crossbow shot, and all kinds of attack equipment went into battle, all kinds of things. Disturbing one after another, like a kaleidoscope. The attack weapons of the Cold Weapon Era have been brought to the extreme.

It is also mixed with some low-level gunpowder weapons, which are very violent.

The defense of the Jin army was also impermeable, first of all, a trench one zhang wide, and this trench was not a straight line, but a zigzag, deep or shallow, which brought great trouble to the advancing Song army; Behind the ditch is a fence made of bamboo, tree trunks, etc., between the fences are tied with finger-thick straw ropes, with thorns on them, and bamboo sticks are tied to the ground in some coke ovens that are not easy to gap.

A bamboo spear more than two zhang long, through the holes and gaps in the fence, forming a dense spear array, the first row of human spears is two zhang long, and the second row of people is also two zhang, then, if the whole phalanx is pierced, then the enemy in front only needs to face a spear, which is easy to avoid. But if the men in the first row turn their spears 45° to the left or to the right, the effect is very different. According to the cosine theorem, the front length of the spear with a 45° turn to the right is no more than 3 meters, and if the distance between the first and second rows is a little more than 1 meter, then the spears in the second row (forward spears) and the right spears are on the same front. Each enemy needs to face two spears. Of course, this is not too much, because if they still rush forward more than 1 meter, the forward spears of the third row are still waiting for him. Under the cover of comrades-in-arms, it is impossible to get close to the frontal sword and shield phalanx. Even the soldier on the far left had to face a spear, and there was little hope.

The dense spear array is difficult to move forward at all, and the front is death.

Of course, it's not unbreakable.

In the world world, there is no unbreakable camp, but they are willing to pay the price.

In the battle, the spear array did not make the Song army afraid, and the Song soldiers held a one-man high shield to form a dense shield long formation, advancing intensively, leaving no gaps, and the spear assassination efficiency was greatly reduced. At this time, the trebuchet was launched, and the explosive bag bombarded, and it exploded into a large area.

You don't need too high an aim, you just need to launch, bomb is enough.

"Boom!"

Violent explosions rang out, bursts of air surged, corpses flew all over the sky, blood scattered all over the earth, desolate and beautiful.

The dense spear array, there were flaws, as if they had been gnawed by dogs, a hole in the east, a hole in the west, no longer strict and not terrible, there was a trace of scattered.

Sergeant Jin flashed a trace of panic, and some wanted to run back, but just looked at the sword and axe hand behind him, endured it, and continued to fight!

At this time, about fifty paces behind the Jin army's fence, some sophisticated archers were shooting, specializing in shooting the Song army's stone-throwing gunners. Some of the arrows were also stained with oil, lit a fire, and fired at the trebuchet, igniting a bag of explosives, killing countless Song soldiers.

It's like ant mobilization, with the fence as the boundary, and the two sides are constantly biting and killing.

And as the offensive continued, the impregnable camp became more and more flawed.

And this flaw was immediately discovered by the charging Song army, and then quickly moved forward, a rushing car, making a squeaky sound, rushing forward, because the trench has been filled, the rushing car impacted, the speed is extremely fast, the force is extremely violent.

Under the huge force impact, the fence was smashed open, some spearmen were also scattered, and some slow Jin soldiers were even crushed to death.

In other directions, several rushing vehicles also rushed into the fence of the Jin army, breaking the protection of the Jin army.

It was originally an impregnable line of defense, but it was broken in an instant.

And the dead soldiers of the Song army rushed in and fought hand-to-hand, constantly tearing the gap and expanding the results.

The battle quickly became fierce, with the impact of the Song army's infantry, the trebuchets behind were also quickly following up, throwing explosive bags to the rear of the Jin army, bombarding the Jin army's large array, and there was a taste of infantry and artillery coordination. It's just very rudimentary, there is no precise calculation, it all depends on feeling, and the infantry needs to control the rhythm of the impact, expand to the wide, and constantly tear the gap, not to develop in depth.

"Knock knock!"

The drums of war are beating and the spirit is murderous!

The soldiers of the Jin Army, mostly from Liaodong, or the land of clouds, are mostly bitter cold places, with strong reputations, proficient in the way of fighting, and the study of fighting, which is the so-called Yan Zhao's generosity. These Jin soldiers, tall and powerful, rushed to kill with their weapons, as if they had entered a no-man's land.

The Northwest Army is also a bitter cold land, the land is barren, the land is difficult to make a living, most of them rely on fighting to obtain income, many years of war, the reputation is also extremely fierce, and it is also good at fighting.

The two armies collided together, the swords flashed, the spears fluttered, and the murderous aura soared into the sky, one by one, and one by one rushed up.

It's like a grinding disc of flesh and blood, strangling the vitality of both sides, and one life after another disappears.

The Song army behind rushed up, more and more, and gradually the fence lost its defensive effect, and the spear also lost its lethality, and some were just melees, like street hooligans fighting, groups of three or five, fighting together, unscrupulously strangling the Jin army.

Gradually, the Jin army was at a disadvantage.

Comparatively speaking, the Jin army was better at attacking than defending, and was losing and retreating in battle, as if it had a rout.

"Woo!"

A trumpet sounded, and the Jin army began to break away from the melee and withdraw towards the second line of defense.

The Song army was covering in the back, and it seemed that they were going to take the opportunity to break through the second line of defense.

It was only that it soon attracted a dense rain of arrows from the Jin army, like raindrops, impermeable, and the Song army's attack form was slow.

Those Jin troops took the opportunity to enter the second line of defense and began to set up defenses.

The first camp of the Jin army fell.

But that's just the first line of defense!

There were also seventeen lines of defense in the back, which were either made of earth and rock, or set up various obstacles, which were more difficult to break through than one layer at a time. Eighteen barracks, connected layer by layer, and heavily defended, are a sturdy tortoise shell.

If you want to break through layer by layer, in addition to the dead, you are still dead. (To be continued......)
