It took only a few minutes to break the hasty defensive line of the new annex army, rush to the end of the siege machine position, and then turn the horse's head and charge towards the dense area of the new annex army. With the gap they opened, the Thunderbolt cavalry following behind them was much more calm, and they methodically threw and lit the oil and burned the siege equipment one by one.

In less than a quarter of an hour, the Mongolian military equipment in front of the infantry camp turned into a blazing fire, which made Hou Xing, who was observing the battle situation with a telescope in the camp, overjoyed, and urgently ordered the infantry to occupy the first and second earthen walls. Although these two earthen walls were smashed into ruins by trebuchets, and most of the trenches in front of the walls were filled, they still had great defensive value. Without the threat of trebuchets and ballistas, musketeers lay behind walls and fired, inflicting great casualties on the charging Mongols. Due to the fear of accidental damage to the siege weapons, the Mongol army did not hold the first and second earthen walls at this time, so the Thunderbolt army easily occupied these two lines of defense.

At this time, the battlefield in the northeast of the camp was still full of killings. The Thunderbolt cavalry, which undertook the task of blocking the attack, and the Mongol elite cavalry led by the lost Lida fought together, and the battle began to heat up. The Mongol cavalry was the best in the world in cavalry shooting, and they did not expect that the Thunderbolt cavalry, which was in a weak position, would take the initiative to charge, and lost three points in momentum.

As soon as the two sides joined the battle, the Thunderbolt army fired a burst of short fire, followed by grenades that split their heads and faces, and the Mongolian cavalry was actually in chaos. In terms of individual combat, one Mongol cavalry can fight as well as two Thunderbolt cavalry, in addition to the difference in horsemanship, because the hit rate of muskets is much lower than that of bows and arrows, and it is extremely difficult for grenades to hit moving targets.

Under the large-scale cavalry regimental battle, the Thunderbolt army and the Mongolian cavalry not only did not have a gap, but had a slight advantage. Due to the large-scale team battles, the formation of the Mongolian army was extremely dense, and the Thunderbolt soldiers did not need to aim, but only randomly slashed the short fire gun of the runner to hit the target until all six bullets in the short fire system were fired. The leather armor of the Mongolian army could not stop the powerful penetration of the bullet at all, and there were even cases of two people injured by a bullet at a very close distance.

In a densely populated battlefield environment, delaying the explosion of grenades is no longer a disadvantage, after all, the Mongol cavalry in front dodged the explosion, but those coming from behind could not dodge the explosion. Exploding grenades are not as lethal as bullets against armored cavalrymen, but their scattered fragments can cause more casualties, and they penetrate more parts of the horse's abdomen and other parts. The Mongol cavalry, devoid of horses, was a lamb to the slaughter on the battlefield, either from condescending chopping or trampling by the horse's hooves.

In only two or three minutes of engagement, the Mongol cavalry suffered more than 200 casualties, while the Thunderbolt cavalry only lost a few dozen people. However, he was also an experienced general, and soon discovered the shortcomings of the Thunderbolt army - poor riding skills and lack of bows and arrows.

To say that Lida's men were worthy of an elite and strong army, with his whistle, the remaining 700 or so Mongolian cavalry broke away and retreated to 50 meters away. At this distance, the Mongolian cavalry can easily shoot at the Thunderbolt army with a short bow on horseback, while the effective range of the Thunderbolt army's wheel fire system is only more than 20 meters, and throwing grenades on horseback is only this distance. The change in tactics caused the Perak army to suffer heavy losses, and the Mongolian army lost more than 50 people in just one round of shooting, which was still the premise that the cavalry brigade of the 3rd Division was generally equipped with shields and chest leather armor.

This tactic of the Mongolian army is called "Parthian tactic", that is, they ride on horses, shoot arrows outside the range of enemy fire, if the enemy chases, they run away, and then stop at the horse to shoot arrows, like kraft candy, it is very difficult, will make the cavalry not as painful as their own army. As for archery while riding horses, even among the Mongolian cavalry, only a very small number of elites can do it, and the hit rate is also low, so the Mongolian cavalry often stops at the horse when archery.

In view of the characteristics of this tactic, the Thunderbolt Army has conducted a special study and has set up a course on dealing with this tactic at the Military Academy. The response is also very simple and crude, using longer-range weapons such as artillery, bed crossbows, and precision sniper muskets. The Cavalry Brigade of the 3rd Division was also equipped with weapons to deal with this tactic - ultra-light small guns for cavalry.

According to the standard response process, some of the Thunderbolt cavalry continued to charge at the Mongol cavalry under the rain of arrows, and some of them used their horses as cover and began to install ultra-light small cannons. This kind of small cannon is actually a tiger squat cannon, due to the use of high-strength steel, the barrel is relatively thin, and the total weight is only 20 catties. The amount of gunpowder it is fixed with is two taels, and the shotgun it launches weighs half a catty, which can cause damage to soft targets within 10 meters of the explosion point, and its only shortcoming is that the effective range is too short, only about half a mile.

The range and power of a superlight cannon is not enough for a fortified fort or infantry with ballistas, but it is more than enough to deal with light cavalry. The cavalry of this kind of artillery thunderbolt army was equipped with one squad and twenty rounds of ammunition, and the five hundred cavalry who attacked this time brought a total of fifty guns, but in the charge just now, they lost six guns, and forty-four remained.

The Thunderbolt cavalry, which charged towards the Mongol cavalry, fell a few dozen more, but their sacrifice bought their comrades time to place the super-new cannon. As the brass trumpet sounded for the retreat, the charging thunderbolt cavalry quickly turned their horses and quickly retreated back to the array. In the process of retreating, more than 20 horsemen fell with arrows. He commanded his men to chase within the range of the arrows, but saw a rumbling cannon sound in the Thunderbolt cavalry array in front of him, and then a large cloud of thick white smoke rose up, and then a large number of cavalry in front of him fell.

The sudden shelling shocked his heart, and he thought that the Thunderbolts had already run out of ammunition. However, as a veteran of the battle, he was also extremely quick to respond, and he immediately ordered his men to charge at full speed. As long as they are entangled with the Thunderbolts, the opponent will no longer dare to open fire.

The response to the loss is undoubtedly correct. At present, although the Mongolian cavalry has lost more than 300 people, there are still more than 600 people, while the Thunderbolt army has only lost more than 100 people, but only more than 300 people, and the number of Mongolian troops still occupies an absolute advantage. Moreover, the Mongol army was not only good at bows and arrows, but also good at fighting with spears, scimitars, bones, ropes and other weapons.

The cavalry of the 3rd Division, although armed with powerful grenades and short muskets, always had limited ammunition. In fact, after the two sides had just clashed, the Thunderbolt cavalry had run out of bullets and grenades, and now the only weapons they had were machetes and shields except for ultra-small artillery.

Just now, when the Mongol cavalry was using Parthian tactics, they had opened a distance of more than 200 meters from the artillery positions of the Perak cavalry. Although the distance of 200 meters was very short, it still took a certain amount of time for the cavalry that had not turned into a charging state, and this time happened to allow the Thunderbolt army's ultra-small artillery to fire another round, knocking down more than 100 cavalry of the Mongol cavalry that rushed to the front, including the lost answer surrounded by his own soldiers.

The Mongols lost so many horses and cavalry under artillery fire that they tripped up dozens of cavalrymen who followed closely behind. In the midst of the chaotic chaos, the Mongol cavalry that followed the charge did not realize that the main general had fallen to the ground and was killed under the chaotic hooves. They still swarmed forward one after another, colliding with the Thunderbolt cavalry rushing towards them.
