The Khitan cavalry, which was huddled in front of the trench, was instantly knocked down by a rain of bullets, and the already somewhat irregular formation became even more chaotic. However, these cavalry belonged to the most elite cavalry of the Khitan, and their generals were all veterans of battle, and although they were in confusion when they were first attacked, the generals who led the troops quickly calmed down and began to command their subordinates to move along the trench to both sides. This can reduce the possibility of being hit by the opponent by constantly moving, and also make room for the infantry behind to fill trenches and dismantle fences.

If these Khitan generals were facing the enemy army of this era, then they were completely right to do so. Even if the arrows fired by the Khitan cavalry did limited damage to the defenders of the city because of the long distance, they were far stronger than those who waited there to be beaten. It's a pity that these Khitan cavalry are now facing a crossing team armed with completely different weapons and equipment and combat styles from this era. Its tactics of plundering the city and throwing arrows into the city did not form enough lethality for the infantry of the "Wyvern Army" equipped with steel helmets and half-body stab-proof armor. And in the face of the dense firepower of the "Flying Dragon Army", their method of evading the attack by quickly moving to the left and right under the city did not work at all - the Khitan cavalry with their bodies facing the city on the side of the city reduced their own goals to the minimum, but increased the goal of straddle the horses to the maximum. In this way, the probability of the Khitan cavalry being shot itself has decreased a lot, but the probability of being shot when they step off their horses has greatly increased, and the result is that more and more cavalrymen have fallen off their horses.

These fallen Khitan cavalry themselves were not many hit by bullets, and many of the sturdy soldiers even stood on the ground unscathed while their horses fell. But before they could laugh out loud at their escape, they were knocked away by the robes who had no time to restrain their mounts, and the knights on their horses would not have reined in their mounts if they did not want to be knocked off their horses by their comrades behind them. At this moment, waiting for them were either trampled into mud by the large group of men and horses behind, or they were knocked into the trench and pierced into a hornet's nest by the sharp stakes at the bottom of the ditch - of course, it was not only the soldiers who were shot and fell off their horses, but also many knights who were not hit in the first place also fell to the ground because their mounts were bound by the people and horse corpses on the ground.

Although they suffered a lot of losses in the process of moving to the sides, in any case, the Khitan cavalry, which was originally crowded together, finally gradually dispersed. However, before the Khitan generals who led the army could breathe a sigh of relief, the situation changed again. With the sound of "hissing, hissing" breaking the sky from overhead, clouds of smoke rose one after another from the formation of the Khitan cavalry, which had loosened and was diverting to both sides, and a huge roar was heard. The Khitan cavalry around the smoke was suddenly blown up, and the formation that had just recovered became chaotic and uncontrollable again. Just when the Khitan generals who led the army were about to restrain their subordinates again and move to the sides again, they didn't know who was leading the way, and the Khitan cavalry, who had been made highly nervous by the blows that came one after another, and they couldn't see or touch them, couldn't hold on anymore, and fled in the direction of their own camp.

However, the fleeing Khitan cavalry had not run far before they ran head-on into their own infantry team, which was hurrying forward. The cavalry, who had already urged their mounts and ran at speed, instantly scattered their own infantry ranks, and some of the impatient cavalry even began to clear their own way with bows and scimitars to clear their escape routes. However, a brigade of tens of thousands of people, where is it said to rush over, not to mention that the infantry ranks also carry a large number of heavy siege equipment, it is impossible to flash the way for the cavalry in a short time. In addition, some infantry who were driven by the arrogance and indiscriminate killing of the cavalry began to fight back with their weapons, so in a very short period of time, the entire Khitan attacking force fell into complete chaos, and countless Khitan soldiers were trampled to death by horses or killed by their own people. The Khitans' first and probably only chance to counterattack that day was cut short in their cannibalism. …,

Seeing that the Khitan counterattack force was completely in chaos and had begun to flee to the Khitan army camp, Qian Yuanshan ordered the infantry and small-caliber mortars to continue to shoot at this group of enemy troops who had become the best target, and on the other hand, he made a pre-agreed haode gesture to the herald at the highest point of the city tower. Seeing the gesture, the herald waved the flag in his hand again. Seeing the flag waving up and down in the herald's hand, the artillery commander immediately made a gesture to the communicator next to him -- the sound of the artillery firing was so loud that even if he shouted into the communicator's ear, the other party might not be able to hear it clearly.

The correspondent had to turn away. In a short time, six large bodies composed of steel frames were pushed out of a corner of the artillery position and pushed out of the south gate of the city under the strict protection of two companies of "security forces". At the critical moment, Qian Yuanshan once again offered his "trump card" - rocket artillery.

In fact, this rocket artillery can have a chance to exert its power again, thanks to the vigorous promotion of Fu Guangsheng, a member of the Weapons Section. As a traverser who has a soft spot for rocket artillery, after completing the first test firing of rocket artillery prototypes, Fu Guangsheng began to lobby his colleagues in the Weapons Section, the Ministry of Science and Technology, and even the Ministry of Military Affairs, hoping that everyone could support his suggestion to increase investment in the research and development of rocket artillery, and increase the number of purchases after the successful development of rocket artillery. It was precisely because of his many persuasions and efforts that not long after the first batch of genuine rocket launchers and about 200 rockets were initially trial-produced, the Weapons Section adjusted its own production Jihua, upgraded the production mode of rocket artillery, especially rockets, from trial production and trial to the level of formal equipment, increased the scale of rocket production before the start of the Youyun occupation, and sent the second batch of 400 rockets to the Yuguan front line before the Battle of Yuguan began. This gave Qian Yuanshan the opportunity to use this weapon system that was most suitable for inflicting a blow on the enemy.

However, considering that the rocket artillery will produce a large amount of smoke and dust when fired, if it is used in Shanhaiguan, it will definitely cause interference to other artillery units and even the infantry units at the head of the city. Therefore, Qian Yuanshan chose his firing position this time on an open field outside the south gate of Yuguan in an effort to minimize the adverse effects of rocket launching. At this time, there were no Khitan soldiers and horses south of Yuguan, and there was no danger that there would be a sneak attack on the rocket artillery company by the enemy -- of course, out of prudence, Wang Kunjun and Qian Yuanshan still sent two companies of "security forces" to protect them.

From the launch of the six rocket launchers at the south gate of Yuguan to the completion of the setting of the launch position and the loading of the rockets, it took about a cup of tea before and after. At this time, after the Khitan army that came to attack Yuguan Guancheng was killed and wounded by the firepower of the "Flying Dragon Army", the originally crowded formation was much looser than at the beginning, which made those soldiers who were eager to escape have a gap to take advantage of, and rushed to their own camp one by one.

Just when the defeated Khitan soldiers were secretly happy because they were close to the gate of their camp, Qian Yuanshan also gave the order to shoot at the rocket artillery company that had completed the preparation for launching. As the company commander vigorously waved the red order flag in his hand, the six rocket launchers were divided into two groups and fired one after another, and in just one or two minutes, nearly 200 rockets were fired into the camp of the Khitan army.

Nearly 200 rockets, trailing orange flakes and shrill whistling sounds, fell like red dragons falling from the sky in less than two minutes, turning large tents into piles of ruins. Such a strong stimulus completely plunged the Khitan army camp, which had been ravaged by artillery fire for nearly half an hour, into chaos.

The first to collapse were the civilian servants. As early as the beginning of the shelling, the deafening sound of the shells exploding, the burning tents that were blown up, and the soldiers who were torn to countless pieces panicked at the time of the soldiers, who had barely experienced a battle formation or even participated in military training. One by one, they either ran around the camp, knelt in a place where they thought they were safe, prayed to God to bless them, or rushed outside the camp despite the obstruction of the Khitan army guarding the camp. …,

Immediately after the dispersal of the servants were those villagers who were temporarily transferred from various prefectures and counties outside the Guan. Although they had at least some degree of military training and some battles compared to the servants, this experience only allowed them to last a little longer than the servants. Moreover, it is precisely because they are closer to soldiers than the servants that they have a deeper understanding and more understanding of the cruelty of the war, the tragic situation after being broken by the enemy army, and the real situation of the first battle of Baoxingzhuang. Thus, when the pressure on them grew, when their fear of death exceeded their fear of military law, their collapse was even faster and more violent than that of the servants, who either tried to dodge or kneel and beg for mercy in the face of the Khitan soldiers' obstruction. In the face of the Khitan soldiers who intercepted them from escaping from the camp, although some of them took the same actions as the servants, more people chose to use the knives and guns in their hands to kill a bloody way to escape for themselves. For the fierce resistance of the villagers, the Khitan soldiers, who have always been accustomed to being on top, and never put the servants, villagers, and even non-native regular troops in their eyes, are obviously a little uncomfortable, and they once had the upper hand in the initial confrontation, and many Khitan soldiers died in the hands of "their own people" in such a daze. By the time the Khitan soldiers reacted and began to use their true skills, there were more than 10,000 villagers and servants who had escaped from the camp.

Such a large-scale rout and escape was a fatal blow to the morale of the army. When more and more servants and villagers participated in the rout, the determination of the Khitan soldiers who were still determined to fight the enemy to the death began to waver - from the beginning of the war to the present, they have not even seen the shadow of the enemy, but they have already taken tens of thousands of lives. Fighting against such an opponent that cannot be seen or touched, no matter how brave and fierce the Khitan soldiers are, there will also be a fear in their hearts, a fear of the unknown and extremely powerful. When this fear accumulated to a certain extent, under the double pressure and inducement of the defeated attacking troops who had fled into the camp and the second rocket that roared from the sky, the Khitan soldiers in the large camp finally followed in the footsteps of the servants and villagers, and completely and completely collapsed.
