After the battle began, Dorgon and the others were far away from the trebuchets, and they also knew that these two trebuchets were the main targets of the enemy's artillery. However, they still didn't expect that Li Yan's subordinates had actually prepared red-hot solid bullets in advance, so that their sturdy-looking trebuchets would be destroyed in a short period of time.

This time they only brought two trebuchets, which were also experimental in nature, to see if they would work well. In the current situation, it seems that there are still some problems.

"Really @ mother @!" Tang Tong muttered: "I'm still going to lay down the Shanhaiguan, but here, in a blink of an eye, our trebuchets will be destroyed." ”

Wu Sangui reminded: "Lord Wang, let's withdraw first, they have attacked." ”

Azig withdrew his eyes from the damaged trebuchet and found that Li Yan's troops were using shields to cover six or seven trebuchets, advancing rapidly. The trebuchet was much smaller than their return cannon, and the structure was much simpler, naturally lighter. In the later positions, infantry and artillery also followed slowly to the beat of drums, and more than a thousand cavalry on each side were on guard.

However, they only had six or seven large Franky and usable general cannons that had been captured in the Ming Kingdom before, and the artillerymen of the Han army were firing shells in a panic to block the enemy's approach. They all knew how powerful the trebuchet was, and when the fire pot hit, it was worse than a cannonball.

The last time I entered the customs, I brought everything that could be used, not only the newly cast Shenwei General Cannon, but also the previously cast and captured cannons. It is to take advantage of the inextricable time between Li Chuang and the Ming Kingdom to grab some territory and restore the glory of the former dynasty Dajin Kingdom. Originally, everything went well, but after the war with Li Yan, it was unexpectedly defeated one after another, and more than 100 cannons of all kinds were abandoned in the pass.

This time they sent troops to harass along the Great Wall, and they had no artillery available. The new Shenwei General Cannon has not yet been cast, and the old cannons are guarded in the capital and major cities, and they cannot be called, so they can only find these guns in the treasury that were not eye-catching before.

Although their shells could also hit the soldiers who were raising their shields in front of them, they had little effect on the catapults that were still advancing. Seeing that the trebuchet was getting closer and closer, and soon approaching a distance of two hundred paces, the artillerymen became even more nervous. They have even forgotten to reload their ammunition and are ready to turn around and flee at any moment.

All they saw was a thick herringbone of wood nailed to the front end of the stone thrower. But what they didn't know was that it was this small move that allowed the stone thrower to move forward safely. When the cannonball hits it, it will bounce away at another angle, and it is difficult to be directly pierced, which has a very obvious protective effect on the stone thrower.

Wang Renfu watched the rapid advancement of the stone thrower, and had to admire Li Yan's whimsy, a simple idea can improve the protection of the stone thrower several times. If it weren't for the fact that the trolley wasn't strong enough to withstand the force of the shells, this would have been a good way to push and release.

In the blink of an eye, the stone thrower entered a distance of two hundred paces, and the soldiers who operated it pulled the rope, and under the action of the pulley, the throwing rod was quickly pulled down and stuck. The loader in the rear carefully carried the fire pot over and put it in the iron net pocket. The igniter blew on the flame, lit the cotton cloth outside, and quickly fastened the flame.

At the sound of the commander's command, the operator released the bracket, and the throwing rod flicked violently, throwing the fire pot out of the net pocket. After that, the commander did not continue to give orders, but looked at the impact point of the first shot, and made some adjustments appropriately before continuing with the next launch.

The fire pot drew an arc in the air, and it seemed to fly slowly, but it also landed very quickly near the Qing army's bunker. Some fell in front of the bunker, some smashed directly on the bunker, and some smashed behind the bunker, instantly igniting a large flame.

At this time, the commander of the trebuchet was directing his subordinates to adjust the direction and tighten the tendons, while the soldiers of the Qing army behind the bunker fled to the rear in a panic, but at this time Azig had not given the order to retreat.

Soon, the second round of fire pots was thrown out. This time it was much more accurate, and most of the fire canisters landed near the Qing army's bunker, turning the bunker into a sea of fire. However, the results of the battle at this time were not large, except for a few unlucky eggs when the fire engulfed in the first round of launches, behind the bunker at this time, the Qing army had already fled.

Azig looked at Li Yan's trebuchets in the distance, his eyes were on fire, and he wanted to ride over and chop them to pieces. But the infantry line behind the trebuchet, dozens of cannons, and thousands of cavalry covering on the flank, made him dare not give the order to attack. He knew that even if all the 1,000 cavalry he wore the white flag were killed, he might not be able to break through Li Yan's line. As for those Han troops, as well as the cavalry of Wu Sangui and others, he didn't dare to completely believe it.

"Withdraw," Dolgon said lightly, "If you hesitate any longer, you will only suffer a big loss." ”

Without waiting for Azig to order, he instructed Wu Sangui again: "King Pingxi, send someone back to inform your subordinates, prepare for defense, and be quick." ”

"Don't want Ironyard Fort?" Gaudí asked. There were 500 of his soldiers there, and it was his territory.

Dorgon said casually, "That's your own business. After saying that, he pulled out his horse and left, without a trace of mud and water.

Azig finally stopped being entangled, and after quickly giving the retreat order, he also took the guards and his elite bannermen to retreat north.

"This, this," Tang Tong said dumbfounded, "What is the matter with Lou Zi throwing trouble at us?" It's easy to relax for half a year, and I'm worried again. ”

Wu Sangui also gave the order to retreat, reminding: "Let's go, when you finish complaining, you may be caught by Li Yan." ”

"Should we send someone to contact Li Yan, I think this Great Qing Kingdom is also nonsense." Gao Di said angrily, and at the same time followed Wu Sangui, who was retreating.

Wu Sangui said helplessly: "Then we must withstand the next attack, otherwise even if we want to surrender, people may not care about us." ”

Wang Renfu watched the Qing army retreat in a panic, and gave an easy order: "The cavalry pursues." Ma Cheng, take your troops to meet in the rear. Be careful, just recapture the Iron Yard Fort, don't overdo it. ”

"Yes!" Wei Cheng of the cavalry, and Ma Cheng of the infantry clenched their fists at the same time. After that, Wei Cheng led the cavalry and chased after the fleeing Qing army.

Almost at the same time, Hauge outside the wall road pass was stunned. He couldn't figure out why there were no defenders at the pass of fierce resistance yesterday morning. He was sure that the casualties of the defenders at the pass were very small, but he had more than 300 casualties here, and there were more than 50 elite escorts under his command in the middle.

"Trap, this must be a trap." He was sure in his heart.
