When the fierce battle on the left front lasted for almost half an hour, the shouting and killing of the left flank became smaller and smaller, and at this moment, suddenly in the rumbling sound of horses' hooves, Wang Rong heard several explosions, and then faintly saw fire and cyan smoke in the dust.

He reacted immediately, it was the crossbowmen who threw the palm grenades they had equipped.

He had originally regarded the crossbowmen's palms as a magic weapon for surprising victory, requiring them to throw them into the opposing cavalry when the Yu army launched a frontal charge, but now the crossbowmen on the left flank had violated his orders and had obviously reached their limit and had to fire.

After a while, the bloodied soldiers rode to the Chinese army and cried, "Holy Lord, there are too many thieves, and the brothers have suffered heavy casualties, and they can't support it anymore, please ask the Holy Lord for support!"

Wang Rong looked at him and asked, "Are you in the first formation?"

The soldier nodded.

"How many of you are left?"

"I don't know, maybe there are only half of the brothers left! There are too many thieves!"

"Wang Xu, Zhang Yunshu."

"The end will be!" The two hurriedly surrendered their hands.

"You take the 3rd Brigade of the Guards and the Guards Division with him to support the left flank." Wang Rong said.

The two received the order, immediately reined in their horses, and led the elite soldiers brought from Yique Pass to gallop to the left front.

At this time, the gate of Yique Pass in the rear opened, and the team came out of Yique Pass and arrived at the rear of Yuan Tiangang, and Meng Sheng also joined the battlefield with his men and horses.

Slowly, the shouts of the left wing became louder and louder, and Wang Wei then asked Zhang Xuan to take away the hundreds of Xiaojie guards around him to reinforce the left front, and all of them filled the left wing battlefield.

After the two sides fought for more than half an hour, the left flank withstood the attack of the Yu army, and the desolate horn sounded in the large array of the Yu army in the north, but the dust in the sky still made Wang Rong unable to see the specific situation, and the left front quickly sent someone to report that the light cavalry of the Yu army had withdrawn, but the two circles in front of the left also suffered heavy losses.

At this time, Wang Tan and Meng Qiong rushed to his side with Yi Que Pass, and when they reached the rear of the army, Wang Rong immediately called Wang Tan and Meng Qiong and asked, "How many soldiers and horses have you brought?"

Wang Tan saluted and said, "Your Majesty, the 3,500 people of the 1st Brigade of the Guards Division are here."

Wang Rong said without hesitation: "Immediately bring your men up and support the left front, the speed must be fast, and there is no time to delay!"

Seeing Wang Rong's serious and anxious appearance, Wang Tan and Meng Qiong didn't have time to salute, and turned their horses' heads to dispatch the army.

Wang Rong knew that the retreat of the Yu army's light cavalry was not to stop the attack, on the contrary, they were making way for the cavalry charge in the rear, and they felt that the Tang army's physical strength and arrows were almost exhausted, so that the heavy cavalry could attack.

The dust in the distance gradually dissipated, the situation on the left flank gradually became clear, looking at it from afar, the situation on the left flank was extremely tragic, the outline of the circle was still there, but compared to the few circle formations in the rear, the two front formations on the left flank were much weaker, and the periphery of the circle was full of many corpses, and there were still a large number of wounded soldiers wailing in the circle.

The mules and horses on the periphery also died quite a lot, and the troop carts were densely covered with arrows, like the mane of a black sow.

There was a hollow area of ten or twenty paces in front of the position, with only scattered corpses and a large number of black-pressed arrows, like weeds growing wildly in the summer field.

On the periphery is a large number of corpses of Yu soldiers and horses, all over the place, in the front area where the two circles intersect, where the crossbow and crossbow of the Tang army have the strongest firepower, the corpses of the Yu soldiers and horses are even piled up into a waist-high hill, blood and water and then the surrounding fields.

For more than half an hour, the two sides fiercely clashed with various long-range weapons, and both Tang and Yu counties suffered heavy casualties.

Wang Rong couldn't estimate the casualties on both sides at a glance, he didn't have time to think about it, the Yuguo cavalry who had been waiting for a long time in the distance opened a long line, and it was slowly coming towards them.

The organization of the Yu army was not as good as that of the Tang army, and after slowly approaching and gradually accelerating, the long cavalry line began to bend and twist, writhing like a water snake.

Wang Rong also knew that the Yu army would not charge directly with arrows head-on, and they would change their formation and insert themselves into the gap in the position after approaching, and attack the Tang army in weak and exposed places with sabers and spears.

That's what it is

The reason for the tug-of-war and attrition of the first half hour consumes their stamina, morale, and arrows, and then enters close combat.

It's a pity that they kept one hand, and Wang Rong also kept one, he had two cavalry units that were waiting for him, and rockets that had basically not been fired.

The war horses of later generations were to be desensitized so that they were not afraid of the sound of guns on the battlefield, but Wang Rong was sure that the war horses of the Yu Kingdom had not been desensitized training.

Looking at the fields and roads in the distance, like a black tide of the Yu army, they are like a forest, swords and guns reflect the sun, on the sparkling river, full of oppression, from time to time someone shouts and screams, endlessly, so that the heralds around Wang Rong also breathe heavier, not to mention what pressure the soldiers facing them at the front will bear.

Wang Rong said, "Order, send out the Vermilion Bird Banner and let the crossbowmen shoot all the rockets!"

The soldiers on the high platform in the rear listened to the order, immediately raised a large red flag under their feet, and began to wave it vigorously, and the vermilion flag was embroidered with golden vermilion birds, which were particularly dazzling in the sun.

Soon, a huge bowstring sound was heard from various positions in the distance, and a large number of crossbow arrows dragging Qingyan rose from the high ground everywhere and threw them diagonally into the distance.

The accuracy of the bed crossbow is limited at a distance of 100 paces, but the accuracy is not so important when facing a tide-like army, as long as the direction is right.

Wang Rong stared into the distance, the Yu army had already reached within a hundred steps, and the war horse was very fast after a long acceleration.

They shouted and screamed, and the raging tide seemed unstoppable.

Soon, many orange and yellow points of light exploded one after another in the long line of the Yu army, blue and black smoke rose and filled, and stumps and severed arms flew everywhere. Every time the light flashed, a large number of people turned on their backs, the people in front fell to the ground, and the people and horses in the rear did not have time to stagger and were tripped one after another. Many frightened horses began to scurry from side to side, or directly stopped, colliding with the people behind.

The forward of the Yu army was less than a hundred steps away from the Tang army's large array at this time, and it was only a blink of an eye distance for the galloping horses, and it was completely too late to stop the horses.

Troop vehicles are a familiar and unfamiliar concept.

Broadly speaking, all kinds of vehicles used in the army can be classified as military vehicles, and military vehicles are still very common in modern armies in later generations, armored personnel carriers, off-road vehicles, trucks, etc.

In the Spring and Autumn Period and the Warring States Period more than 1,000 years ago, there were few cavalry, few military vehicles, and they were mostly used as chariots.

By the time the Han Dynasty arrived, as the Han Empire changed its strategy from a state-level defense to an all-out offensive, it faced more and more cavalry enemies, and the combat area became more and more complex, from the jungles of Vietnam to the Yunnan-Guizhou mountains, the Korean mountains, the Gobi steppe, and the desert of the Western Regions.

In the face of various complex terrain, massive cavalry, the chariot gradually lost its role.

But soon, Wei Qing, a general who fought against the Xiongnu all the year round, found that the other side or so of the car, the army was marching, and a large amount of heavy grain and grass could not be carried by people and horses.

People's physical strength is limited, do more and eat more, the physical strength of horses is expensive, many times if the Chinese cavalry is not needed for war, they are dismounted and walked on the way to the march, so that the war horse can maintain its physical strength, and wait for the enemy to get on the horse and start the war.

Therefore, a cart with wheels has become the best choice, which can not only save effort and load more materials, but also use donkeys, mules, horses and other livestock to pull, greatly reducing the difficulty of logistics and supply for the army, and can also replace horses with other livestock.

Moreover, in the subsequent battle with the Huns, Wei Qing found that these vehicles usually transported materials, and they were all deployed in front of the position during the battle, and the fixed wheels could be connected together to build a temporary long wall, so that the opposite cavalry could not rush in, and could protect the soldiers in front of the large array and resist the impact of the cavalry.

As a result, the military vehicle changed from a chariot in the Spring and Autumn Period and the Warring States Period and the Qin Dynasty to a transport vehicle and a defense vehicle.

Since then, there have been many changes and variations of military vehicles, such as the knife cart that blocks the gate, the nest cart used for reconnaissance, and the cave house cart that resists the rolling wood and stone of the siege party approaching the city wall.

But there is no qualitative change in the overall usage, and it is still Wei Qing's

The road, which has been used for thousands of years, is mainly to ensure logistical supplies, soldiers' armor, weapons, arrows, food, bedding, firewood knives, pots and bowls, etc., can be placed on military vehicles when marching, and pulled by donkeys or mules, horses, etc.

When necessary, unload the things and push them to the front of the formation to form a troop formation.

The military vehicles of the Tang army have developed for thousands of years from the Qin Dynasty and the Yongguo Kingdom, and the overall change is not big, the military vehicles have two wheels, there are iron bars as a strengthening structure, and the front door is high on both sides, and it is driven down.

During the war, the wheels were fixed on the ground, and the wheels were tied with iron cables between the carts, and the front door panel was erected, and there were card slots left by craftsmen during the manufacture of the carts, so that swords could be inserted, and spears could be fixed on both sides.

Because it is a circle formation, there are gaps between the carts from time to time, and these gaps are tied to the mules and horses pulling the carts, this trick is learned from the learners, people will be afraid to flee in the face of cavalry charges, but mules and horses will not.

In this way, the perimeter of the position became an impregnable wall, and even the most powerful cavalry could only bypass it, trying to attack the Tang army behind the car formation with spears and bows and arrows from the gaps.

But the rockets disrupted the tactics of the Yu army, the dead and wounded, and the frightened horses in a large area, causing the Yu army to be chaotic, and most of the people did not have time to change the formation, interspersed from the open space between the car formations, but rushed straight to the car formation.

Wang Rong sat in the rear, he looked from afar, the front of the Yu army stretched forward like a rolling wave hitting the shore of the solid stone, instantly splashed, split, broken into one section after another, the Tang army's car formation is a solid stone.

The horses and people crashed into the car formation at high speed, making loud noises and screams in an instant, and if the car formation was not a whole of hundreds of vehicles, I was afraid that it would also be scattered.

For a while, the flesh and blood flew sideways, and the stumps flew indiscriminately, and many Yuguo cavalry desperately reined in their horses, not wanting to crash into a large number of swords and spears in front of the car formation, but they were collided by their comrades who had no time to slow down behind, and were pushed to the front of the car formation with huge force The cold sword and spear were instantly knocked out of many holes.

There were also many soldiers of the Yu army who rode war horses and wailed into the car formation, and people were thrown off the horseback due to inertia, fell into the Tang army's position, and were immediately chopped into pieces of meat by random knives.

The military vehicles at the front of the large army vehicle formation were squeezed and gurgling, the Yu army was squeezed into a ball in front, the soldiers of the Yu army in the front were squeezed into the military vehicles, blood gushing out, and they couldn't die anymore, the spearmen of the Tang army took the opportunity to use a spear of about a zhang to assassinate desperately through the military vehicles, and the bows and crossbows in the rear also shot indiscriminately, and they wailed all over the field for a while.

Wang Rong watched from afar, paid close attention to the battle situation, and found that the military vehicles in the third vehicle formation in front of him were squeezed by a large number of Yu troops, and the wooden military vehicle wheels could not withstand such force, and there was a click explosion, and the wheels on the ground were cracked and disconnected, and the military vehicles were pushed open by the dead bodies of the Yu army, revealing a gap.

When the Yu army found out, they tried to squeeze into the gap, and Wang Rong was very worried from behind, but he soon found that his worries were unnecessary.

In the position, the Tang army was dressed in full body armor, armed to the teeth of the elite armored infantry with axes and spears in their hands and quickly blocked, the Yu army that lost the advantage of horse mobility was not the opponent of the well-equipped Tang army at all, a large number of Yu troops were cut down and stabbed to death at the gap, and they could not rush in, there were Yu troops outside, and dozens of elites of the Tang army at the gap were full of arrows, like hedgehogs, but they still danced with axes and spears without stopping, and cut down the Yu army with men and horses who dared to rush in.

Soon after, a hill of corpses piled up in the gap, blood stained the surrounding land, completely blocking the road behind, and the Yu army could only climb the corpse wall if they wanted to come in, and they could not ride horses.

On the other hand, a large number of Yu cavalry who avoided the frontal rush into the gap between the Tang army's positions were even more uncomfortable.

They originally imagined that they would constantly attack the Tang army with spears from the gaps, and the scene of consuming the Tang army with horsepower did not exist at all. In front of them is a wall of military vehicles that cannot rush in, and between these open spaces, at least two directions can be crossfired, and most places are surrounded by Tang army bows and crossbow arrows, there is no way to dodge, there is no way to dodge, there is no way to dodge.
