Seeing the cavalry of the Thunderbolt Army chasing after him, Yang Dayuan panicked at first, but after seeing that the other party was nothing more than a thousand light cavalry trapped in Pengxi Village by himself, his heart calmed down again. In his opinion, he still has 5,000 elites, and the Thunderbolt cavalry will not dare to charge head-on. As long as the threat of reinforcements arrives, it will naturally be lifted, or it will take only two more days to reach Qingju City.

Yang Dayuan was still looking forward to the arrival of reinforcements at this time. The Mongol cavalry traveled quickly, and it only took less than a day to reach Qingju City, and even if they came from Dahucheng, it only took about five days. If the Thunderbolts still refuse to retreat as soon as the reinforcements arrive, they can work with the reinforcements to flank the front and back. The shame of the defeat of Xuepeng Xizhai with a big victory also comforted the soul of his nephew Yang Wen'an, who died in the battle in Mianshui. Pinching his fingers, with the foot strength of the Mongolian cavalry, reinforcements should have arrived.

Yang Dayuan knew that Kipchak was being beaten by Zan Wanshou in Diaoyu City at this time, and although the main force of his infantry cavalry was still there, the grain and grass were all lost, and more importantly, he also had a fear of artillery, where he was willing to send cavalry to run long distances? However, Kipchak was also a slippery head, and although he had led his army to evacuate from Diaoyu City, he still wrote back that he was in the midst of a fierce battle with the Perak army in Hezhou and could not divide his troops.

What's more, in order to prevent Kublai Khan from blaming him in the future, the Kipchak sent elite cavalry to relay the rescue letter to Niu Lu and Wang Weizheng in Beichuan, who were on their way to Qingju City, claiming that they would not be able to send troops in a fierce battle with the Perak army, and asked them to send cavalry to reinforce them. The Mongolian army in Sichuan also has factions, and the Kipchak is not the same as Niu Ling and Wang Weizheng, and Niu Ling has just escaped from Cao Ergou's pursuit, so he is willing to go to danger again. Wang Weizheng had already led a large army to Zitong, ready to take advantage of the situation to take Mianzhou, and naturally refused to come to the troubled waters.

In order to prevent the onslaught of the Thunderbolt cavalry, Yang Dayuan ordered the spearmen to stay on the periphery of the queue, and the crossbowmen to stay behind the spearmen to deal with the cavalry with long-range shots. This is a standard tactic against light cavalry. The spear is the best melee weapon against cavalry, and the infantry bow is much stronger than the cavalry bow in terms of range and strength. This is also the reason why the Mongol light cavalry did not charge easily, but used Parthian tactics to gradually consume the infantry.

The cavalry of the Thunderbolt Army were all light cavalry, and Wu Qing would not be stupid enough to attack the hedgehog formation of the infantry. He also used Parthian tactics against Yang Dayuan this time. Although the Thunderbolts were not good at riding and shooting and were not equipped with bows and crossbows, the cavalry was equipped with ultra-light small cannons with a range of half a mile, which could "fly kites" against the new annexed army. The Mongolian cavalry could use a cavalry bow with a range of tens of meters to make the infantry miserable, and although the cavalry of the Thunderbolt Army was not as good as the Mongolian elite cavalry, it was not difficult to use small cannons to make Yang Dayuan's infantry exhausted.

As soon as the two sides fought, the new annex got a taste of the power of this upgraded version of Parthian tactics. The small cannon has several times the range of the cavalry bow, which allows the Thunderbolt cavalry to fire more calmly, and even have time to aim and correct the impact point. These shotguns, fired from half a mile away, could easily penetrate leather armor, although they could not penetrate iron armor. Although the new annexed army of Yang Dayuan's department has a armor rate of 50%, it is mainly leather armor and paper armor, and the number of iron armor does not exceed 20%.

Wu Qing scattered the 1,000 cavalry under his command into companies around the new attached army columns, allowing each company to attack freely. As rounds of small cannons were fired, the formation of the new annexed army was peeled off layer by layer like an onion, and the outermost soldiers fell one by one.

Yang Dayuan hurriedly ordered the sword and shield soldiers to charge, and ordered the crossbowmen to shoot at close range. It's just that the Thunderbolt soldiers saw a large group of newly annexed soldiers rushing towards them, put away their small cannons, turned over and rode away, where can they catch up? When the soldiers of the new annex army were tired and panting and stopped the pursuit, the Thunderbolt soldiers stopped their horses again, quickly installed the artillery, and fired again. Seeing this, the new annex began to charge again, and the Thunderbolt soldiers rode away again.

After a few rounds of this, the new annex army was also tortured to exhaustion, and the soldiers lost a few hundred men, while the Thunderbolt cavalry had only a dozen or so wounded by the crossbows because they could not retreat. The situation on the battlefield has developed to such a state, which is completely unexpected by Yang Dayuan. He knew that if he continued like this, after the remaining forty miles, his 5,000 men and horses, if not killed by the artillery, would be scattered due to the collapse of morale.

Yang Dayuan thought that there were only two ways to deal with this Parthian tactic using artillery. The first is to take advantage of the darkness to escape to a nearby hill, and then find a mountain path back to Qingju City. In this way, the retreat will be a rout, there is a lack of water and food in the wilderness, there are pursuers, and there will be many deserters, and it is estimated that not half of the soldiers will be able to return to Qingju City. The second is to camp on the spot, dig trenches and build walls to hold on, and wait for reinforcements to arrive.

After much consideration, Yang Dayuan decided to hold on to the spot and wait for reinforcements to arrive. When night fell, he sent several groups of fast-paced dead soldiers to Qingju City to rescue. According to his prediction, these dead soldiers will arrive at Qingju City at noon tomorrow after a night's journey. The cavalry of Qingju City set off immediately after receiving the message, and arrived at the battlefield the morning after tomorrow. When the time came, the Thunderbolt cavalry could only retreat in a huff.

Seeing that the new annexed army was shrinking into defense, Wu Qing was not in a hurry. His purpose was to delay the new annexed army, so he immediately led the army to block the road to Qingju City, and sent people back to Pengxi Village to report to Cao Ergou and ask him to come quickly. Due to the outnumbered enemy, it was not the best time to attack before reinforcements arrived. Due to the lightly armed pursuit, the ammunition of the Thunderbolt army was almost exhausted, and the lethality of the cavalry small artillery was weak, and it was acceptable to deal with light and unarmored targets, and it was difficult to penetrate the shield, let alone deal with the civil barracks.

The dead soldiers sent by Yang Dayuan rushed all the way and brought the distress letter back to Qingju City. At this time, the elite of the city has been taken to Diaoyu City by the Kipchak, and the only soldiers in the city who can fight are the soldiers and horses of the Niu Ling Department who just arrived in Qingju City yesterday. Daru Huachi in the city hurriedly approached Niu Lin and asked him to send troops to help. Under the pretext that the soldiers and horses were tired and unable to fight after a long march, Niu Ling only sent two scouts, one to the place where Yang Dayuan was blocked, and the other to Pengxi Village, ready to explore the reality.

He was mainly responsible for the strategy of Xichuan, and did not have jurisdiction over the Kipchak of the Marshal Dongchuan's office. When he was surrounded by the Perak army in Fushun, he did not see the Kipchak send troops to help. Now that he finally escaped from Cao Ergou's pursuit, how could he risk his life to rescue Yang Dayuan's new annex army? It's just that he was also afraid of the Kipchak attack, so he still asked Kudu to prepare for sending troops. If the Thunderbolt army confronting Yang Dayuan is weak, it can go forward to reap some battle merits.

Another day later, when the scout cavalry reported that the Thunderbolt army blocking Yang Dayuan was no more than 1,000 cavalry, Niu Lu's heart became active again, and he ordered Kudu to lead his 2,000 cavalry to reinforcements. Kudu and his subordinates had already suffered enough from artillery, and they were reluctant. Helplessly, the military order was difficult to disobey, so I had to grind on the road. The forty-mile road took a day, which was slow for the cavalry.

Kudu led the army to arrive, which made Yang Dayuan overjoyed. It's just that the greater the hope, the greater the disappointment. These Mongol cavalry were outnumbered, but they refused to attack, but only watched the battle from afar. Suddenly, he understood that there were more than 3,000 Thunderbolt troops at this time. Although there were 7,000 men on the side, they still had half the advantage in strength. But he has fought with the Thunderbolt army many times without a victory, and he knows that the Thunderbolt army is terrifying, and he is really afraid.

Kudu's judgment was not wrong, and just before he arrived, the Thunderbolt army also came with two reinforcements. The first was the 400 cavalry left by Wu Qing in Pengxi Village, and they also brought a lot of ammunition supplies. The second was the 2,000 Banzhou army led by Yang Bangxian, and these tough Miao Jiang warriors traveled lightly and quickly all the way, and they were able to rush to the battlefield before the arrival of the Mongol cavalry.
