Early in the morning, Yuangai Suwen inspected outside the eastern city, the biggest problem here is that the ground is uneven, but it is a deep pit of rocks, and it is difficult to move an inch of heavy siege, it can be seen that the Khitan did not attack from the east and west sides, but after entering about two hundred steps close to the moat, the ground becomes level, and the problem of attacking the city is not big, and more importantly, Yuangai Suwen found that there are not many trebuchets on the east and west sides, and it is far from being as dense as the north and south city walls.

Although Yuangai Suwen was waiting for the siege weapons sent by Yancheng, he also wanted to know how well the Sui army could defend the city, not necessarily a large-scale siege, and it was necessary to try to attack once, and it was necessary to feel the details of the Sui army.

Thinking of this, Yuangai Suwen ordered: "The second order is to stop preparing and attack the city in half an hour!" ”

This time the Goguryeo Western Expedition army mainly came from the local army, basically with 1,000 people as a local battalion, Yuan Taizuo also carried out a centralized establishment, with five local battalions as a stop, about 5,000 people, equivalent to the army in the Sui army, the leader is called Duhou, there are five battalions below, and the owner of each battalion will be called Qianyong.

The weapons of the Goguryeo army were mainly spears, both bronze spears and iron spears, and they were dressed in leather armor and wore hoods on their heads, and their combat effectiveness was very strong.

Half an hour later, the drums outside the east city were loud, five thousand soldiers quickly assembled, the shouts of killing continued to sound from the army, murderous, at the same time, a low horn sounded on the head of the city of Liucheng, the Sui army gathered in the east city from all directions, and the situation of the enemy attacking from the east city was already obvious.

There are indeed not many trebuchets on the eastern city, only thirty, far less than the one hundred and twenty in the southern city, this is because there are no large siege weapons such as ladders outside the eastern city, and the enemy cannot organize a large-scale attack, and even if the attack is a small-scale tentative attack, there is no need to deploy too many defensive weapons.

The deployment of the Sui army was not wrong, Goguryeo's attacking army was indeed not much, only five or six thousand people, Yang Shanhui immediately judged that this was just a tentative attack by Goguryeo, since it was a temptation, of course he would not bring out his true strength.

Yang Shanhui immediately ordered: "Send 3,000 Sui troops and 3,000 militia soldiers to guard Dongcheng, and the rest of the troops will go back to various places to be on guard, waiting for my order." ”

Although Yang Shanhui was a Taishou, he was undoubtedly also a master who was very good at defending the city, and he mixed regular soldiers and militia groups to defend the city, combining the virtual and the real, so that the Goguryeo people could not figure out the true strength of the Sui army.

In addition, Yang Shanhui also wanted to try the ladder breaking technique and fire attack technique that they had just successfully trained, and the 5,000 Goguryeo army came just in time.

The defenders at the head of the eastern city were constantly changing formations, thirty trebuchets were already in a state of readiness, three thousand soldiers were ready to fight with bows and crossbows, and thousands of militia soldiers carried the rolling wood and haystacks to the eastern city wall, and although everyone was sweating profusely, their faces were full of confidence in victory.

At the same time, the Goguryeo army under the city also entered the final assembly stage, compared with the Khitan army, the biggest feature of the Goguryeo army is that the team is neat, their pace is not fast, but the march is uniform, revealing a powerful combat power, the expressions of several Sui army generals on the city wall are solemn, if they go out of the city and fight with the Goguryeo army, I am afraid that it will be them who will lose, not the Goguryeo army.

"Taishou, throw the thistle thorn!" General Lu Chifeng asked the Taishou Yang Shanhui.

Yang Shanhui shook his head, although they had 30,000 quenched tribulus thorns in their hands, but Yang Shanhui was worried that once the Goguryeo people collected these tribulus thorns, I am afraid that the last unlucky Sui cavalry, he can't just try to be happy for a while, he must consider the overall situation, this is the difference between Taishou and generals, Taishou will consider the problem in the long run.

"Prepare the boulder!"

The Goguryeo army was walking through the undulating rocky terrain and was almost within range of the trebuchets.

At the head of the city, the Sui army's thirty trebuchets began to creak apart, and a piece of boulder was put into the iron net pocket, after the first battle with the Khitans, Li Chun adjusted the arm distance of the new trebuchet, and set up a clever lever, so that the trebuchet projection frequency greatly increased, and it was also more solid.

The stones the size of the grinding disc were put into the throwing bag, and Lu Chifeng gave an order, and thirty trebuchets were launched at the same time, and thirty boulders were thrown high, tumbling in the air, drawing an arc, and slamming into the dense crowd.

"Boom!" There was a loud bang on the ground, screams arose, several Goguryeo soldiers avoided it, and were smashed into meat cakes by the boulder, the huge inertia made the stones roll in the crowd, fast and abnormal, rolling out more than 20 steps in a row, the Goguryeo soldiers desperately dodged on both sides, but still more than a dozen people died under the collision of the boulder, and more than 20 people were injured, their bones were broken and their tendons were broken, and the wailing sounded together.

Immediately after the second, third, and fourth rounds of trebuchets were fired, accompanied by the Sui army's bows and crossbows, the arrows on the city were like dense rain, and the city was heavily killed and wounded.

The trebuchet played an incomparable role in the defense and siege of the city, in the Three Kingdoms era, the trebuchet was a necessary weapon for the army to attack and defend the city, in the battle of Guandu, the Cao army used hundreds of powerful trebuchets to destroy tens of thousands of Yuan troops, laying the foundation for the final battle of Guandu.

It was the same in Goguryeo, the Sui army used the world's most advanced trebuchet, causing huge casualties to the attacking Goguryeo army.

But the Goguryeo army was not overwhelmed by the brutal blows of the trebuchets, and after paying the price of nearly 1,000 casualties, they finally rushed to the bottom of Dongseong, where arrows rained down on the city's heads, and Goguryeo soldiers raised their shields to meet them, and people continued to fall down from arrows.

As long planks were erected on the moats, siege ladders began to be hung on the city walls, and all the eighty siege ladders carried by the Goguryeo army were put into battle.

Yuangai Suwen rode a horse and stood on a dirt slope two miles away, watching his army attack Liucheng, the sharp trebuchet of the Sui army was in his expectation, he did not care about the casualties caused by the trebuchet, he cared about the level of defense of the Sui army and the specific means of defense.

The appearance of the trebuchet means that the Sui army has long-range defensive weapons, and the Sui army's trebuchet can actually throw five rounds in a short running distance of two hundred steps, more than double the trebuchet they captured before, which makes Yuan Gai Suwen secretly frightened, but at the same time it also stimulates his curiosity, how strong is the defense of the Sui army?

As a qualified commander, knowing oneself and knowing one's opponent is the most important part, and one must pay a price to understand the details of the other party, and Yuan Gai Suwen knows this very well, and he is ready to sacrifice these five thousand soldiers to understand the defense of the Sui army.

"Give me a drum to fight!" Yuan Gai Suwen shouted loudly.

'Boom! Boom! Boom! Boom! ’

The loud and dense sound of war drums echoed across the battlefield, urging the besieging Goguryeo soldiers to storm the city.

Rolling wood and stones fell like hail on the top of the city, and groups of soldiers screamed and rolled down the ladder and fell into a trench full of sharp piles, which were filled with the corpses of the soldiers who had died in the misery, and many of the undead soldiers were stuck in the sharp stakes and struggled and howled, which was terrible to see.

At this time, the soldiers at the head of the city lit the torches, and then dozens of large grass piles were thrown down the city, and the torches were thrown on the grass piles under the city, with a large number of grass balls and shrub dry branches bundles thrown down by the soldiers, the bottom of dozens of siege ladders began to burn fiercely, and the Goguryeo soldiers on the siege ladders were frightened and desperately climbed up, but they were ruthlessly pierced through the chest by the sharp spears of the Sui soldiers, and fell into the fire below with a scream.

Many of the soldiers could not stand the scorching fire, jumped from the siege ladders, and most fell into the trenches, facing another kind of death.

More and more haystacks were thrown down, and a sea of fire gradually formed on the city wall, and countless people were ignited by the fire, and became fire men, who opened their arms and ran back with wailing, and before they had taken a few steps, they fell to the ground, and the fire burned them to the ground.

Before they even had time to use the combination of broken ladders with forked claws, the Goguryeo offensive was completely engulfed by the fire, and the Goguryeo soldiers watching the battle from a distance were all pale with fright, their legs trembled, and even the main general Yuangai Suwen was dumbfounded, he had never seen such a tragic fire to defend the city.

Finally, he let out a long sigh and shouted, "Collect the troops!" ”

The bell rang, and the remaining more than 2,000 frightened Goguryeo soldiers turned around and fled in the direction of the camp.
