Early the next morning, the Sui army began to act in accordance with Yang Guang's battle plan. Among the 1,130,000 Sui troops, except for Yang Guang's 30,000 Imperial Forest Army, they all launched an attack in accordance with the proposed combat objectives. All of a sudden, the military camp, which stretched for dozens of miles, surged outward like boiling seawater.

The target of the attack of Yu Wenming's Zuo Ling Guard was Liaodong City, the first important town in Liaodong. Of course, because the Goryeo army in Liaodong City was also the largest, there were as many as three Sui troops attacking here, namely the Zuo Ling Guard led by Yu Wenshu, the Right Ling Guard led by Yang Yichen, and the Zuotun Guard led by Dugu Luo.

The walls of Liaodong City are all made of hard bluestone, which is very strong and durable, and can resist the attack of ordinary trebuchets. Moreover, its walls are as high as 20 zhang, and the general ladder is not so long. There were also three moats and a moat outside the city walls. The gates were also built with great skill: they were built on a recessed section of the wall, and if the enemy tried to hit the gate with a crash, they would be attacked on three walls. This is also the reason why in the eighteenth year of the emperor's reign, Yang Jian led the army to attack Goryeo, and finally returned in vain.

Because the walls of this city are tall and wide, the city has plenty of grain, grass and arrows, and there are four acropolis at the four corners of the city to defend it, and the strength of the city is the highest among all the cities in Goryeo, so it is easy to defend and difficult to attack.

However, the Sui army was also well prepared, and siege equipment such as catapults, siege vehicles, well railings, and arrow towers were all prepared. In addition, they had much more troops than the Goryeo army, so the soldiers of the Sui army were still very confident.

"Woo-woo-" With a low sound of horns, the Sui army began to move and attack.

The three squares of about 30,000 Sui sabers and shield soldiers walked in neat steps, slowly moving forward to a distance of 150 zhang from the city wall, standing outside the range of bows and arrows, and in the middle of the phalanx, there stood four tall arrow towers and two siege vehicles.

The chief general of the Goryeo army stationed in Liaodong City was Ulmoon Zhideok, known as the first general of Goryeo, and he was also entrusted with the important task of resisting the Sui army by Gao Yuan, the king of Gyolyang in Goryeo, and had the right to mobilize the troops of the whole of Goryeo.

Looking at the Sui army swarming under the city, he sighed and said: "This time they have dispatched siege vehicles, it seems that they want to storm our city gate, and it is estimated that our army will face a fierce battle today." ”

The Goryeo soldiers defending the city had already been in battle for a long time, and without the command of Yiwen Zhide, they had already pushed ballistas and catapults onto the city wall, and then began to bombard the phalanx of the Sui army.

The Sui army was tasked with the attack this time by Yang Yichen's Youling Guard, and with his order, the Sui soldiers poured towards the walls of Liaodong City like a tide. At the same time, the trebuchets under the city also began to fight back. Arrow towers and siege engines also began to move towards the city walls.

"Attention! All ballistas and catapults focus on enemy turrets and siege vehicles! Yiwenzhide ordered.

The catapults on the city walls began to shift their targets, throwing boulders at the Sui army's arrow towers and siege engines. Fourteen years ago, during the battle of Yang Jian's attack on Goryeo, the Sui army also dispatched the arrow tower.

They condescended and inflicted a large number of casualties on the Goryeo soldiers on the city walls with bows and arrows.

Therefore, the Goryeo army also learned a lesson, as soon as the Sui army's arrow tower appeared, all catapults and ballistae would give priority to attacking the arrow tower.

After a long period of learning techniques from the Central Plains, the accuracy of Goryeo's catapults has been greatly improved, and under the command of the officer, several stones have hit the first arrow tower of the Sui army.

However, the arrow tower only shook a little, but it was not destroyed.

This surprised the Goryeo generals on the city wall, and they took a closer look, only to find that the arrow tower was actually wrapped with a thick layer of iron sheet, which greatly increased the strength of the arrow tower, and made the rockets of the Goryeo army completely ineffective.

There was originally a moat and three moats outside the city of Liaodong, but they were quickly filled in by the Sui army's removal of earth regardless of casualties and relying on the tactics of crowds. Of course, the Sui army also paid heavy casualties. The four towers continued to move slowly towards the city walls, and entered the range of the Goryeo army's bows and arrows.

"Shoot the arrows!" Yiwenzhide ordered loudly.

"Whoosh-whoosh!"

As the Goryeo army began to fire arrows, the Sui archers on the arrow tower also immediately returned fire, and the two sides began to shoot at each other.

Inside and outside the city of Liaodong, there was a sudden shouting of slaughter, and the battle was very fierce.

After nearly two hours of repeated fighting, the Sui army and the Goryeo army were still in contention, but the Sui army, as the attacking side, naturally suffered heavy casualties.

After lunch, the Sui army went on the offensive.

This time, the Sui army put the cloud ladder on the city wall and climbed to the top of the city, but because the Goryeo army was very well prepared, fishing nets with hooks were set up on the side of the city wall, and the soldiers of the Sui army who rushed to the city head fell into the net and were killed by the Goryeo army with spears. They could not gain a foothold in the city, and had to retreat again.

The next day, according to the battle plan, the Sui army was changed to attack by the Zuotun Guards led by Dugu Luo, and Yang Yichen's Youling Guards were replaced. After also paying heavy casualties, he finally cut the fishing net with a sickle and barely gained a foothold on the city.

At this time, Yiwen Zhide saw that the situation was not good, and personally led the guards to kill him. When the Goryeo army saw that the commander was also personally clothed in battle, their morale was greatly boosted. In the midst of the shouting, they made concerted efforts to drive the Sui army down again.

However, Yiwenzhide knew that although he barely managed to hold the city, the fishing nets on the city wall had been completely destroyed, and most of the trebuchets had been smashed. There were still cracks in the city walls, but they were too late to repair. If the Sui army continues to attack like this tomorrow, I am afraid that the city will inevitably be broken.

And the next battle turned out to be as he expected. On the third day, the attacking Sui army was replaced by the Zuo Ling Guard led by Yu Wenshu. They recuperated for two days, and it was the time for them to live. The Goryeo army** was already very tired for two days, and the defense capability in the city was not as good as before, and they finally couldn't support it after desperately resisting for half a day.

The southern, northern, and western three city heads all had Sui army hoplites ascend the city, and under the leadership of Luo Cheng, Yuwen Chengdu, Yu Wenming and other brave generals, a consolidated city head position was established. So that the follow-up soldiers can continue to climb the city wall and devote themselves to the continuous attack of reinforcements.

At this time, Yiwen Zhide suddenly felt overwhelmed, although he had already personally put on the battle, and at the same time mobilized all the young and middle-aged people in the city to the city. However, compared with the elite Sui army, there is still a big gap in combat effectiveness.

The waves of Sui troops that came up have made the Goryeo people feel a little endless, as far as the eye can see, under the Liaodong city that has already been stepped on the ground, the black pressure is full of Sui soldiers, spears are like forests, swords are like snow, arrows are like rain, and the Sui army flags fluttering in the wind are even more obscuring the sky.

From morning to noon, although the Sui army attacked desperately, the city was rushed up by the Sui army several times, but in the end, it was barely held under the left and right branches of Yiwen Zhide.

It's just that the 20,000 Goryeo soldiers in the city, plus the strong men he mobilized, have now fallen almost half, and the remaining half are basically all wounded. And at this time, Yiwen Zhide discovered a terrible thing: a brave general with a phoenix winged flow gold boring appeared in the Sui army, he climbed the west of the city, and killed the Goryeo army crying father and mother. Many brave generals of the Goryeo army stepped forward to fight with them, but they were all killed by one of them, and they were able to fight with them in the second round.

Due to the bravery of Yuwen Chengdu, before noon, the city wall on the west side of Liaodong City fell a small half. This made the defender of Liaodong City, Yiwen Zhide, pale pale. It's just that he is now entangled by Luo Chengjun, who is attacking the northern city wall, and he can't pull out troops to support at all.

In desperation, Yiwenzhide had no choice but to order a surrender letter to be shot out of the city.

He experienced the great battle between the eighteenth year of the emperor and the Sui army. He vaguely remembered that the emperor of the Sui Dynasty seemed to be very good-looking. Yang Jian originally came with a large army in a fierce manner, but after the king of Goryeo expressed his willingness to submit to the Sui Dynasty and become a vassal, he withdrew his army.

The letter of surrender was soon picked up by the cavalry of the guards who had been roaming outside the city and had been brought by Yue Zeng Province. They immediately delivered the letter to Yue Zeng.

When Yue Zeng saw this letter, a knowing smile suddenly appeared on his face, secretly thinking that the Koreans were finally willing to surrender.

"Pass my orders! Mingjin retreats! I'm going to negotiate with the Goryeo Shogun and hold a surrender ceremony! Yue Zengxing shouted in that sharp rooster voice......

At this moment, Yuwen Chengdu is in high spirits on the head of Liaodong City, waving phoenix wings and flowing gold boring. Everywhere you go, you are clothed. The Goryeo soldiers almost died with him. The armor of his whole body had been dyed red, like a bloody man.

However, he had already reached the stairs at the gate from the city wall, and he only had to take a few dozen steps further to occupy the place, and then open the gate and enter the city.

Just when Yuwen Chengdu was preparing to occupy the city gate and make the first contribution to this battle, he suddenly heard the sound of gold. This is the commander's order to summon the siege officers and soldiers back.

"What? Now Mingjin retreats? The gates are about to be stormed! Yuwen Chengdu looked at the less than fifty Goryeo soldiers standing at the city gate, and then looked at the more than two hundred Sui army hoplites behind him. I can't help but suspect that something is wrong with my ears and that I have heard the wrong sound.

At this time, Qu Tutong, the chief general next to him, sighed and persuaded: "Chengdu, collect the troops!" This order was definitely not given by the great general, but by the subordinate envoy Yue Zeng. If Qu Mou's prediction is correct, nine times out of ten, the Koreans said that they would surrender, so Yue Zeng Province let us all withdraw. ”

"How does this work?" Yuwen Chengdu's face turned red, and he glared angrily: "More strength!" At most, with just one meal, we can open the city gate and break through Liaodong City. If we withdraw now, won't we have lost all our efforts? ”

Qu Tutong is a veteran in his fifties, and he naturally sees the current situation more clearly than Yuwen Chengdu. He smiled bitterly and said, "Chengdu, the order of the envoy cannot be disobeyed!" Now his orders work better than the generals. And the consequence of disobedience to military orders is beheading. Even if you're the grandson of a great general! Can't you remember the lesson of Li Jie? He is the son of Li Hun, the Qing of Guanglu Temple, and the heir of Li Valve's next head of the family, who was beheaded by His Majesty's order just because he opposed the decision of the Holy Lord to set up a surrender envoy. If you don't listen to this father-in-law's orders, I'm afraid that you will end up ......."

Although he didn't finish his words, Yuwen Chengdu naturally knew what it meant.

His eyes flickered for a moment, his heart turned a few times, and finally he had to give up. After all, although he is straightforward, he is not a stunned young man. It is important to capture Liaodong City, or is it important to take his own life, Yuwen Chengdu is still clear.

So, there was an indignant look on his face, and then he turned around, and a word burst out from between his teeth: "Withdraw!" ”
