At the same time as the Kudu cavalry charged on both flanks, Yelumaizhu also buried his head and leaned down, hiding half of his body behind his war horse, and rushed towards the Thunderbolt army without stopping. In order to repay the Mongols for avenging the Khitan, in order to prove the strength of the Mongolian Han army, for Liu Heima's knowledge and kindness, and for the promotion after the victory. Surrounded by him, dozens of his own soldiers rushed in front of him, followed by the five hundred lightly armed cavalry, and half a mile behind the two hundred heavy cavalry. Although the horses of the hoplites were taller and stronger, their armor was too heavy to run fast, and they could not run long distances at all, so they had to warm up by jogging first, and then sprint within two miles of each other.

The majesty of the charge of more than 700 cavalry was very terrifying, especially those heavily armored cavalry, hundreds of horses' hooves were stomped on the ground at the same time, as if someone was beating a drum with a heavy hammer in his ear, which was simply torture for the nerves and hearts of those who were not strong-willed. Jerumaiju understood that there was still a distance of two or three miles between might and victory. At that moment he clasped the horse's neck with one hand and pulled the reins with the other, and could not spur the horse, so he clamped the horse's belly with his legs. The trained horse is extremely humane, and his mount is even more spiritual, and he immediately exerts four hooves and rushes out more than ten meters away. Seeing this, the soldiers around him also followed closely. The main general also led the light cavalry behind him, and they accelerated forward one after another.

When the Mongolian cavalry had just rushed into the two miles in front of the Thunderbolt infantry formation, Cao Ergou ordered the cannon to be fired. In the midst of the continuous artillery fire, a dense stream of shrapnel slashed the Mongolian army's sagittal charging array by one-third. Iron projectiles the size of soybeans flew all over the sky, piercing through the leather armor of the light cavalry and tearing apart the flesh and blood of the horses and soldiers. Yelumaizhu was also hit by more than a dozen shotguns, but unlike the leather armor equipped by ordinary soldiers, he was equipped with an iron helmet, and his torso was also covered with chain mail from the Western Regions, so he did not hurt the vital parts, only a few minor injuries to his limbs. His leather-armored mounts and ordinary soldiers were not so lucky, and if they were hit by a scorching iron projectile, they would be either killed or wounded.

The cavalry of the Mongol Han army, which had suffered heavy losses, still headed towards the Thunderbolt army, stepping on the fallen horses and the bodies of their companions, and was tripped and fell a lot for a while. The reason why they were indomitable was that on the one hand, Yelumaizhu fell to the ground, and no one gave the order to change the formation or retreat, and on the other hand, because the speed of the charge was too fast, and the horsemanship was not as good as that of the Mongolian cavalry in the Kudu Division, so it was really difficult to turn the horse's head at high speed. No sooner had the cavalry rushed past the fallen horses and the dead and wounded, and the Thunderbolt artillery rang out in dense intensity, and the light cavalry that was charging at a gallop fell by a third. The rest of the cavalry did not turn or stop, still stepping on the fallen horses and their companions and charging towards the Thunderbolt formation. In the blink of an eye, the distance between the two sides was only three hundred meters.

The third round of artillery bombardment immediately sounded, and a large number of Mongolian cavalry were hit and fell to the ground, and only more than 200 cavalry remained of the more than 500 cavalry charged, and the distance between the two sides was only more than 100 meters at this time. It should be said that these Mongol and Han cavalry were also extremely brave, and they still rushed straight to the Thunderbolt army formation. It is said that they also know that 200 horsemen cannot break through the defense line of Thunderbolt at all, but they still charge desperately, and they are worthy of the name of the self-proclaimed Northland warriors. But how can flesh and blood fight against iron and fire? The distance of more than 100 meters seems to be a short time, but it is an out-and-out death zone. The more than 200 cavalrymen who charged desperately were either dismounted by the scattered triangular nails, or were bombarded by the buried mines and flew into the air, and only 100 or so horsemen saw that they could not do anything, so they turned their horses and fled back. Anyway, if they don't escape, muskets, grenades, and heavy spears await them.

Just as the light cavalry was fleeing back, Liu Heima's heavy cavalry entered the position of more than two miles in front of the Thunderbolt army. Although these black-clad heavy cavalry only had two hundred horsemen, the sense of oppression brought by them was much stronger than that of the five hundred light cavalry just now. They were in a wedge-shaped array, and their mounts struck the ground heavily and neatly, not fast, but faintly thunderous. The threat of hoplites succeeded in attracting the attention of the Thunderbolts, helping the fleeing hussars to attract fire. I saw Cao Ergou waving the flag, and the thunderbolt army's firepower aimed at the light cavalry poured into the oncoming heavy cavalry queue.

After the smoke of gunpowder, the imaginary harvest scene did not appear, those heavy cavalry only lost more than ten horses, and the brigade still rushed straight to the Thunderbolt army formation, which caused a burst of exclamation in the Thunderbolt army formation, and the invincible artillery actually had an effect Liao Liao, and anyone would be a little panicked. As the distance between the two sides shortened, the sense of oppression brought by these Xuanjia cavalry became stronger and stronger, and even caused sporadic commotion among the Thunderbolt soldiers, but under the loud shouts and reprimands of the officers, they quickly regained their calm. Seeing this, Cao Ergou urgently ordered the artillery to no longer be loaded with shotguns, but with solid iron bullets. The heavy artillery and light artillery of the field division have special shotguns and solid shells, of which the solid bullets weigh several pounds, and the light ones are as big as eggs, and are mostly used to attack the enemy's fortifications and siege equipment.

When the Black Heavy Cavalry rushed to a mile in front of the Thunderbolt formation, the Thunderbolt artillery opened fire again. The scorching solid iron balls of dozens of large and small guns ploughed the charging heavy cavalry to pieces. Although the hit rate of solid bullets is not high, but the power is powerful, especially the solid bullets fired by heavy artillery are even more powerful, often after smashing the Mongolian army in front of the people and horses, they will still continue to fly until all the horses and cavalry on the same line are knocked down, forming a flesh and blood alley. The iron armor of these heavy cavalry could not stop the solid bullets at all, especially since the distance between the two sides was only a short mile. In fact, at this distance, even the shotguns fired by the heavy artillery will penetrate the iron armor they are equipped with, and if they get closer to about 100 meters, the shotguns fired by the light field guns will also cause heavy casualties to the heavy cavalry.

Before the Thunderbolt army used artillery, the Song army had few ways to deal with the heavy cavalry of the northern nomads, and the effect was not satisfactory. Bed crossbows, trebuchets, boiling oil, etc. can be used in the defense of the city, but the nomads are not fools and will use cavalry to attack the city. In the face of the charge of heavy cavalry, the Song army did not have effective weapons to fight head-on, except for building field fortifications in advance. Rejection of horses, triangular nails, and spears can only injure a small number of heavy cavalry who rush to the front, once the rejection of horses is destroyed, triangular nails are consumed, and spears are broken by punching, it is a one-sided slaughter. In the face of the heavy cavalry of the Jin people, the famous Yuejia army had to send dead soldiers to cut the horse's legs with hook and sickle, horse sabers, and long-handled axes, and then swarmed the enemy after falling off their horses. It's just that this tactic has huge casualties, not to mention the success rate, and it is often still broken up by the Jin army.

It is no exaggeration to say that artillery is the real nemesis of heavy cavalry. This round of solid bullets caused Liu Heima's heavy cavalry to lose about 70 horses, which can be described as heavy casualties. Amid a wailing and screaming, the Thunderbolt gunners nervously reloaded their ammunition while the heavy cavalry continued to charge. At present, the distance between the two sides was only more than half a mile, and under the huge inertia, these heavy cavalry could not turn at all, so they had to rush forward, and greeted the baptism of the second round of solid shells dozens of meters in front of the Thunderbolt formation. Due to the extremely close distance, the artillery not only has a significant increase in hit rate, but also greatly increases its lethality. After this round of artillery fire, Liu Heima's heavy cavalry was left with only more than 20 horsemen.

Under the heavy fire of grenades and muskets, the heavy cavalry that had rushed to the front of the Thunderbolts was wiped out. The enormous inertia caused the corpses of men and horses wrapped in iron armor to slam into the formation, even smashing several vans and a low wall. Seeing this situation, Cao Ergou was afraid for a while, and secretly called it a fluke.
