Although the heavy cavalry was invincible and invincible, it was precisely because of the various weaknesses of the heavy cavalry that it gradually began to disappear on the big stage of war, and then it was replaced by the rapid development of light cavalry and cuirassiers, which became the master of the battlefield.

Similarly, the hoplites gradually gave way to the cuirassiers for similar reasons, and gradually brought gunpowder weapons to the stage of war. Although this is a fairy world, Lin Xiao doesn't know if he will follow the same path in the future as his original world.

However, judging from the current war environment, the power of heavy cavalry is still the most powerful, especially for the Sui army with weak troops at this stage.

Li Qing led the charge of 20,000 heavy cavalry, and in just one round, he completely annihilated the remaining barbarian army of cowardly Xue knights, of course, not all cowardly Xue knights were killed by the Sui army, but all the cowardly Xue knights were now overturned on the ground.

Moreover, heavy cavalry battles are not only the charge of heavy cavalry, they are often followed by a larger number of light cavalry, which is used to expand the results of the battle and chase the north. Although the cowardly Xue knight was put to the ground by the heavy cavalry of the Sui army and did not die, the iron hooves of the subsequent light cavalry trampled on them, which made these iron cans scream again and again, and it was even more miserable - they did not die under the swords and spears of the Sui army, but were trampled into meat by ten thousand horses, which was really a tragic enough way to die.

The defeat of the cowardly Xue army and the total annihilation of the Sui army really made the ordinary barbarian cavalry frightened, and without waiting for the order of their own commander, they had already begun to turn around and turn to the rear-what to fight? What to fight? What to fight with the cowardly Xue army, what can a group of cavalry from the herdsmen do? If you don't flee at this time, when will you escape?

Not only were the more than 100,000 barbarian cavalry who accompanied the cowardly Xue army to fight in despair, but even the barbarian Great Khan Tama himself was already dumbfounded, and even the first wave of barbarian cavalry who fled back to their own camp did not give the order to be beheaded - this is the habit of the barbarian army, and the barbarian army that abandoned the battle and fled without the order of the rear commander was beheaded.

Tama's distraction was the first to open a precedent for the barbarian army to flee: more than 100,000 barbarian cavalry fled to the main formation, and the front one actually ran back to the tribe safely, which made the barbarian army behind very happy, and the other barbarian troops who were still in the array saw that the Chinese army did not have an order, but they thought that the Great Khan Tama where the Chinese army was located did not intend to continue the battle, and was ready to retreat, so almost all the small and medium-sized tribes began to quietly retreat.

Chasing the dead and chasing the north is the most physically exhausting, but it is also the most able to stimulate the combat effectiveness and will to fight of the soldiers on the winning side, watching the heavy cavalry led by Li Qing open the channel of victory for the Sui army (the barbarian cavalry began to flee to the rear), Li Hu's order was not slow at all, followed by Li Qing's 20,000 heavy cavalry began to rest and feed the horses, and let the light cavalry who followed the heavy cavalry also began to take turns to guard and rest, at the same time, the Sui army in the rear was supplemented by the barbarian army's forward war horses by the infantry cavalry, and began to launch a pursuit behind the fleeing barbarian army- It was not intended to take the opportunity to destroy the 100,000 barbarian cavalry, but to drive and drive the defeated barbarian army to attack their own formation.

As a matter of fact, the only thing the 100,000 barbarians who were frightened by the annihilation of the cowardly Xue army wanted to do at this time was to flee and flee to a safe place! Where is the safest place? Naturally, it is the location of their own clan. In order to flee for their lives, they dared to kill all who stood in their way, no matter who they were, even the barbarian Great Khan Tama too: their eyes were now full of blood.

Although the rout of the 100,000 barbarian army caused turmoil in the barbarian army's morale, after all, the main force of the barbarian army was still far away from the battlefield where the two armies were fighting, and they did not see the process of the annihilation of the cowardly Xue army clearly, so even if Tama did not order the punishment of the deserters in time, it was after all a hidden danger for the subsequent collapse of the barbarian army.

If it is said that after Tama came to his senses, he was going to order the more than 100,000 cavalry that had fled, but he did not have enough time, because the rout was followed by the heavy cavalry of the Sui army, which had been well rested.

Like the tactics used by the barbarian cowardly Xue army, the heavy cavalry of the Sui army also used a sharp arrow formation, and the first one was Li Qing, a peerless fierce general with a hideous mask.

No matter how good the war horse is, it will be exhausted after running for two hundred miles, and the heavy cavalry led by Li Qing did not rush over on horseback this way, but took the cart that the Sui army had prepared for a long time, rested all the way, and came to a distance of about two miles in front of the barbarian army. In order to avoid the heavy cavalry not having time to mount their horses and launch an attack, Li Hu also sent more carts, loaded with the archers and crossbowmen of the Sui army, dragging the eight hundred ballistae that had been in full swing before, and laid down the formation before the heavy cavalry.

Attacking the enemy with an unstable foothold is a criterion that every general of the unified army is familiar with and must abide by. The barbarian Great Khan Tama, is no exception.

Just when the cart of the Sui army appeared in front of the barbarian army, Tama who was angered by the Sui army's great arrogance of fighting more with less immediately ordered the barbarian tribal cavalry around him to launch a charge against the Sui army.

Two miles, the distance is not far, and the cavalry charge is a matter of the blink of an eye, and it just maximizes the impact of the cavalry, so Tama is still very confident in the charging barbarians.

Once again, however, the truth was beyond Tama's expectations. Originally, the fifty groups of 5,000 cavalry failed to charge in turn, and Tama had already been put into 2/3 of his elite, and when he saw the Sui army that had not gained a stable foothold, he was satisfied that he could get back the fruits of victory, but he was once again slapped by the Sui army in a resounding slap.

If the cavalry of the barbarian army in the first stage is from small and medium-sized tribes, and the organization and discipline are very poor, then the current attack is the medium and large tribes that are more closely related to the barbarian royal court, and their cavalry is more elite and more disciplined, then they should achieve enough results in the face of the Sui army, after all, they now have more than 200,000 troops, which is more deterrent and combat effectiveness than the first stage of attacking the Sui army in turn.

However, what greeted these barbarian cavalry was a continuous rain of arrows, but this kind of arrow rain was not the kind of arrows that were only the thickness of the little finger that were common to the barbarians, but a crossbow gun with the thickness of two fingers!

You must know that the distance of two miles is generally about two thousand steps, and the range of Li Hu's crossbow can easily reach this distance, so don't look at the Sui army staying two miles away, in fact, as long as the ballista is moving forward at a distance of two or three hundred steps, it can launch a crossbow gun to directly hit the banner of the Chinese army of the barbarian army, which is where Tama is located!

The reason why he didn't do that was actually because of the iron guards around the barbarian Khan, those were all dead soldiers of the Great Khan in iron armor, and when they encountered danger, they were a group of people who could block the eyes of the Great Khan, and the strike effect of the crossbow gun was not necessarily good, and it was better to kill and injure a large number of barbarian living forces.

So the scene of the massacre of the cowardly Xue army half an hour ago was staged again in front of Tama, but this time, there was no appearance of the crescent moon knife wheel.

The firing of only 400 ballista carts opened up blood-colored alleys in the onrushing barbarian cavalry, but it did not stop the barbarians from continuing to attack. However, what awaited them was the subsequent crossbow fire of the Sui crossbowmen.

Only the thumb-thick crossbow arrows are not as long as the arrows fired by the longbow, only about half the length, but these crossbow arrows are all made of fine iron, and the three-edged arrows are known as armor-piercing cones, not to mention that the elite of the barbarian army in armor is already few, even if they all pounce, they have to kneel when they encounter the three-edged armor-piercing cones launched by hard crossbows - ordinary iron armor can not stop this specially designed crossbow arrow.

The barbarian army in iron armor could not resist the hard crossbow shooting of the Sui army, and there was no iron armor, at most only a leather armor of the barbarian light cavalry, and under the shooting of countless hard crossbows, people turned over on their backs, and fell one after another in front of the Sui army.

However, even so, the leaders of the barbarian tribes who followed one after another saw that the cavalry was getting closer and closer to the chariot formation of the Sui army, so the leaders who thought that victory was in sight began to personally lead the attack.

As everyone knows, this is in the hands of the Sui army. The Sui army was not afraid that the barbarian army would take the initiative to attack itself, but what it was afraid of was that the barbarian army would break and flee, because after all, the Sui army's strength was still a minority, and once the barbarian army broke and fled, the Sui army was bound to divide its forces to pursue it, so as to prevent the chaotic army from inflicting heavy damage on the border residents of the Great Sui Empire; however, once the troops were divided, the Sui army, which was already in a weak position, might be ambushed or surrounded by the superior barbarian army, and a small number of Sui troops that encountered the enemy's superior strength and lacked the necessary weapons and supplies and defensive equipment in the pursuit could cause the danger of annihilation of the entire army.

However, the barbarian army can take the opportunity to encroach and make a comeback, causing the Sui army to win first and then defeat, which is also intolerable to a general like Li Hu. Therefore, the Sui army must kill and wound a large number of barbarian troops in battle, reduce the number of barbarian troops to the extent that the Sui army can cope with it, and now when the Sui army brigade attacks, the bulky ballista can keep up with the main force in time, so as to give the barbarian army a strong blow.

Finally, more than 3,000 barbarian cavalry broke through the arrow rain blockade of the Sui army's crossbow guns and crossbow troops, and came to a position about a hundred steps in front of the Sui army, which could already pose a threat to the Sui army's crossbowmen and crossbow troops.

Seeing this situation, the Sui army immediately turned the cart that had already been emptied on its side, forming a wooden wall that was more than half a person high, and between the wooden wall and the wooden wall, there was a terrifying spear with a rod length of three zhang - this is another large killing weapon of the Sui army that specializes in dealing with the impact of cavalry, the Sui army called it the "dragon lance", and in the Ministry of Industry of the Great Sui Empire, it was an official name: the horse rejecting gun.

This spear is not made in one piece, but is divided into three sections, and when used again, it is directly assembled and used. The tail of each repulsor pistol has an oblique disc stuck behind the pistol, when the repelling pistol is used, the pistol is inserted into the ground, and the oblique disc is to allow the repelling pistol to stand stably tilted without relying on manpower, all that is needed is for the soldier to hold the rejecting pistol left and right so that it will not fall to the left and right.
