After the Perak Army occupied Guankou Village, they immediately blocked the connection between the Chengdu Mongolian Army and Weimao Prefecture. Liu Heima naturally refused to agree. However, the Perak Army had strengthened the walls of Guankou Village and had the firepower support of the navy's artillery and warships. The Mongolian army, let alone attacking Guankou Village, would be violently bombarded even if the rangers came even slightly closer. Liu Heima had no choice but to use a fort-fort-fort strategy, and built a fort five miles east of Guankou Village, and stationed a force of 100 Mongolian cavalry and 500 new auxiliary troops here to harass and attack the Perak Army and wait for opportunities to break through. The road between Wei Mao and Wei Mao.
This tactic of the Mongolian army initially caused Guankou Village a huge headache. These Mongolian cavalry are like buzzing gadflies, making people nervous at any time and making it difficult to sleep at night. They chased but failed to catch up, and the artillery hit rate was poor. It is said that the ammunition inventory in Guankou Village is not large, and there is no room for waste. In response to this situation, Yu Zhu asked Ouyang Xuan for instructions and sent the field brigade cavalry battalion over to use cavalry to control cavalry. Although the cavalry of the Perak Army was far inferior to the Mongolian cavalry in mounted shooting skills, they were equipped with firearms, and the battle loss ratio between the two sides was almost the same. However, the number of the Perak cavalry was several times that of the Mongolian cavalry. Therefore, after a fight, the Perak cavalry suppressed the Mongolian cavalry in the camp and did not dare to come out. They even used hit-and-run tactics and frequently bombarded the Mongolian cavalry with cavalry cannons. Military barracks.
"Exchanging one's own way for another's body", the guerrilla tactics of the Perak Army cavalry made the Mongolian army miserable. They had no choice but to stick to the camp during the day and secretly leave the camp at night. They extended the trenches outside the camp to the outside and dug a large number of trenches. This method was effective and greatly reduced the number of attacks by the Perak Army's cavalry on the fortress. This method of restricting cavalry with trenches was first used by the Pili Army of Guankou Village. However, Guankou Village was located on the side of a mountain. The soil was hard and it was difficult to dig trenches. The number and density of trenches were insufficient. In addition, the Mongolian army was skilled in horsemanship, so its effect was limited. The Mongolian army's camp was located on a plain. It was originally fertile and loose cultivated land. It was extremely easy to dig up the soil. In a short time, the area around the camp was crisscrossed.
After the Battle of Jiading, Yelv bought his cavalry back to Chengdu, and Liu Heima dispatched 300 cavalry to the direction of Guankou Village. These three hundred cavalry were combined with the original cavalry. Although the number was similar to that of the Perak Army cavalry, their combat power was better than that of the Perak Army cavalry. Therefore, the initiative on the battlefield fell into the hands of the Mongolian army again. Although the Mongolian cavalry suppressed the Perak Army cavalry, they did not dare to approach within two miles of Guankou Village - if the number was small, they would be attacked and killed by the Perak Army cavalry, and if the number was large, they would be shelled.
The suppressed Perak Army cavalry also took the opportunity to attack the Mongolian camp, still using the tactic of bombarding with small artillery and running away. However, unlike the previous one that was unscathed, this time many people were killed and injured, and more than ten horses were lost. The reason for these casualties was the use of new ammunition in the Mongolian trebuchets. In the past, the Mongolian army's trebuchets only fired stones, and their hit rate was very low. They could not hit the fast-moving cavalry at all. During the Battle of Jiading, the Mongolian army suffered heavy casualties from grenades fired by the defenders from trebuchets, so they also installed new ammunition. The Mongolian army used two types of ammunition, one was iron melon bullets filled with gunpowder, and the other was clay pots filled with unknown liquid. Although the lethality of these two types of ammunition is not comparable to that of thunderbolt weapons, they are better in terms of their larger killing range. The Perak Army cavalry, whose speed was restricted by the trenches, was killed and wounded by these two weapons. After getting this news, Ouyang Xuan ordered people to find out these two weapons, and at the same time reorganized the cavalry battalion and stationed it in the Qiongzhou Field Brigade. The horses of the Perak Army are hard to come by, and it takes even more time to train elite cavalry. They really cannot withstand this kind of consumption.
When the Mongolian cavalry saw that the Perak Army cavalry was no longer engaging in head-to-head confrontation and that there was nothing they could do against Guankou Village, the Mongolian cavalry went to attack the Perak Army checkpoint two miles away from the stronghold. As long as this level is broken, the road to Wei Mao can be opened. The Perak Army built two walls here. The first was a fence made of waist-thick logs, and the second was made of stone and cement. However, only half of it was built at the moment and it would take some time to complete.
Due to the narrowness of the pass, there was only one platoon of the Perak Army guarding it. Also because the wooden fence could not withstand the weight and recoil of the fortress cannon, it was not equipped with artillery, but only with muskets and grenades. Yu Zhu was not worried about the safety of this checkpoint before. In his opinion, the Mongolian army must use siege equipment to break through the fence, but before the Mongolian army could assemble it in front of the checkpoint, the fortress artillery of Guankou Village would destroy these siege equipment. The instrument becomes a part. Although it is not easy for a fortress cannon to hit a person two miles away, it is not difficult to hit a huge siege equipment. Therefore, the Mongolian army had previously tried to seize the checkpoint through sneak attacks, but the soldiers of the Perak Army guarding the checkpoint were very alert. The Mongolian army's sneak attacks left dozens of corpses behind each time and had to retreat in embarrassment.
Only two days ago, the pass almost fell into the hands of the Mongols. In the morning of that day, the Mongolian cavalry went out in full force again and called for formation three miles in front of Guankou Village. During this period of time, the Mongolian cavalry did not know that the Perak Army cavalry had withdrawn. They just did not dare to confront them head-on, so they went to the stronghold every day to provoke and scold them. The obscene words made the soldiers of the Perak Army furious, and they all asked Shi Zhongshu, the commander of the garrison brigade in Guankou Village, to fire. Shi Zhongshu remained unmoved and just asked the soldiers of the Perak Army to scold him in return. Brother Xuan said that before the new arsenal is put into production, ammunition must be used sparingly. As one of the veterans of the Pili Army, Shi Zhongshu admired Ouyang Xuan very much. He witnessed Brother Xuan develop a deserted food collection team into today's powerful Thunderbolt Army, and he also went from a small militia leader in Liuliba to a battalion commander, and he was deeply moved.
Just when Shi Zhongshu was sighing, he caught a glimpse of a fifty-man cavalry team heading towards the checkpoint. He was not worried about this and did not order the bombardment in front of the checkpoint. In his opinion, these cavalry were just harassing them again. It's just that these cavalry didn't stop in front of the checkpoint to yell, but rushed straight to the gate. After rushing to the arrow range, part of the Mongolian cavalry fired arrows to cover, while the other part continued to rush forward. This part of the cavalry brought two horses, and the empty horses carried a package. The soldiers of the Perak Army guarding the checkpoint did not panic. They looked calm and hid their arrows behind the fence, preparing to wait for the Mongolian cavalry to approach and then attack them head-on.
Under musket and grenade fire, only two-thirds of the thirty Mongolian troops rushed to the gate. They did not throw the rope hook as before and then pull the rope to climb over the fence. Instead, they took out two kinds of balls, one black and one white, from the package on the back of the empty horse-the black one was the iron ball and the white one was Clay balls, thrown at the defenders on the fence. Under the firepower of the defenders, some of these balls were thrown onto the fence, and some fell to the ground because the Mongolian soldiers were shot. Whether these spheres were thrown on the fence or fell on the ground, they all exploded, and a raging fire broke out after the explosion.
Just as the cavalry attacked the pass, a large group of new auxiliary troops lined up from the direction of the Mongolian camp. When the level exploded, Shi Zhongshu felt that something was wrong. Now it seems that the Mongolian cavalry team is obviously going to raid the checkpoint, the cavalry outside the stronghold is here to block the door, and the new auxiliary army is preparing to camp after taking the checkpoint. Fortunately, after a series of explosions, the direction of the level gradually became silent. It seems that despite heavy losses, the Perak Army still held the level.
