On both sides of the river, a large number of civilian ships were forcibly confiscated and burned by the Sui army, and the Sui army's tactics were very clear, to completely destroy the water power of the Goryeo army and ensure the safety of the logistics base on Ayaluo Island.

On the surface of the Zhuanshui River, Sui warships can be seen patrolling along the river, searching for all the hidden ships.

Although the navy is still busy on the river, the battle of Goryeo has changed its protagonist, and as the main force of the Sui army begins to land, the navy has transformed into a supporting role.

The main force of 30,000 Sui troops landed about five miles away from Pyongyang, on the north bank of Zhuanshui, a group of Sui troops lined up neatly, this is the most elite 30,000 troops of the Sui army, if it is not for the purpose of occupation, then this army can sweep Goryeo.

5,000 cavalry, 3,000 Mo sword troops, 3,000 strong crossbow troops, 15,000 spearmen, 3,000 sword and shield troops, and 1,000 scout troops.

Wearing a golden helmet, iron armor, and a sword in his hand, Yang Yuanqing's eyes were sharp and sharp, and he was escorted by dozens of generals to inspect his men who had traveled a long way.

A group of Sui soldiers with bright armor and spears like a forest, murderous, they had already finished the formation, just waiting for the order to set off, Yang Yuanqing's eyes turned to the east, only to see the northeast, a huge city standing on the plain.

At this time, his first sneak attack plan could not be realized, and more than two hours had passed since the beacon was ignited, and the Goryeo army must have known that the Sui army was coming.

In fact, the second set of plans for a quick battle is no longer realistic, even if the Goryeo army cannot clear the wall in just over two hours, but the army can still go to the city and mobilize the people to assist in the defense.

What's more important is that there are a large number of weapons in the treasury of the Goryeo army, and with the prevalence of Goryeo civilian weapons, it is entirely possible to mobilize 70,000 or 80,000 young and strong people to go into battle.

Yang Yuanqing also knew that it was not so easy to seize the capital of the Goryeo, and if he wanted to plunder a large amount of supplies, he had to pay a certain price.

Yang Yuanqing drew his sword and galloped in front of the army. His voice echoed in the air, "This is a battle of shame, but also a battle of revenge, the defeat of the Sui army will become a loud voice under our iron hooves, let us plant the Great Sui Red Flag on the head of Pyongyang!" ”

The morale of the 30,000 Sui soldiers was high, and the crowd was excited, and they raised their arms and shouted: "We will win!" The Great Sui will win! ”

Yang Yuanqing reined in his horse and turned to the soldiers. He shouted: "In the name of the commander of the Great Sui, I promise to the officers and soldiers of the three armies that the first one to attack the head of the city will be rewarded with five thousand taels of silver, and the official will be promoted to the third level." Take Pyongyang City, everyone will have a generous reward, and those who are killed in battle will be doubled! ”

Under the reward. The morale of the Sui army began to rise, and Yang Yuanqing waved his sword at Pyongyang. "Let's go!"

Groups of Sui soldiers began to march towards Pyongyang, with infantry in the center and cavalry guards on both sides, in a neat line, swords and spears glittering in the sun. The prelude to the war gradually began, and the clouds of war hung over the city of Pyongyang......

King Ko Jianwu of Goryeo stands above the city. Looking at the Sui soldiers from the plain under the river from a distance, the Sui army array was murderous, accompanied by the sound of marching drums, the lineup was mighty and powerful.

In the distance, on the wide surface of the Zhuojiang River. The warships are like a long city wall, and the masts converge into a dense forest. Obscuring the sky.

Gao Jianwu's face was pale, and there was a tremor between the two strands, although the Sui army only had 30,000 people, the strong combat effectiveness they showed when they marched made Gao Jianwu, who had been on the throne for less than a year, begin to be afraid.

He even thought about his fate if he was captured by the Sui army, and even thought of the tragic situation after the Sui army entered the city.

But he is the king of Goryeo after all, and he can't lose the dignity of a king, and he can't affect his morale because of his fear.

He also shouted to the Goryeo defenders: "Hold the city, our reinforcements will arrive soon!" ”

His shouting did not attract echo, not because the morale of the Goryeo army was low, but because his shouting was too small, only more than a thousand people around him could hear it, and his slogan had no incitement to arouse the echo of the Goryeo defenders.

The desertion at the head of the city made Gao Jianwu more and more uneasy, and at this time, his brother, Gao Jiande, the general of Pyongyang's city defense, stepped forward and persuaded: "The king should return to the palace for the time being!" It's not safe here, and if the situation changes, the lowly will report it immediately. ”

Gao Jianwu nodded, and was just about to go down the city, when suddenly, a Sui cavalry in the distance rushed to the bottom of the city wall, and shouted in Goryeo: "On the orders of His Royal Highness the King of Chu, send a letter to the King of Goryeo!" ”

He stretched out his bow and arrow, and a letter arrow shot at the head of the city, and a soldier picked it up, ran to Gao Jianwu, knelt down and presented the letter.

Gao Jianwu took the arrow letter and pulled out the headless arrow, the letter was written in Chinese characters, and the front read: 'Yang Yuanqing, the regent of Chu, the regent of the Great Sui, to His Royal Highness the King of the Goryeo Plain. ’

Gao Jianwu heard the cavalry's shout just now, and looked at the letter in front of him, he became more and more frightened in his heart, it turned out to be Yang Yuanqing's personal expedition.

He tried his best to restrain the nervousness in his heart to prevent the soldiers from seeing the panic and uneasiness in his heart, but his hands were still trembling slightly, he opened the letter, Yang Yuanqing was very frank in the letter, and directly prescribed three conditions:

First, Goryeo compensated 500,000 stone of grain, 100,000 taels of gold, and 300,000 horses of silk as a prerequisite for the withdrawal of the Sui army.

Second, Goryeo ceded the Liaodong Peninsula to the Sui Dynasty.

Third, Goryeo officially declared itself a vassal to the Great Sui, and the king of Goryeo accepted the canonization of the Sui Dynasty.

Agreeing to these three conditions, the Sui army could not attack Pyongyang and withdraw its troops and return to the Central Plains, otherwise the Sui army would break through Pyongyang and wash the city of Pyongyang in blood.

At the bottom of the letter, Yang Yuanqing wrote down a deadline and gave him a reply within two hours.

Gao Jianwu was unacceptable to none of these three conditions, and now he finally understood that there must have been financial difficulties within the Sui Dynasty that the Sui army took advantage of Goryeo's idea and sent an expeditionary force to sack Goryeo.

He let out a long sigh, turned around and walked down the city, life and death are up to heaven! He didn't want to defend the city anymore.

The 30,000 Sui troops were divided into ten phalanxes and arrived at the western city of Pyongyang one after another, and lined up two miles away from the city.

Pyongyang is divided into an inner city and an outer city, the inner city is a city within a city, with a circumference of 12 li, palaces, government offices, official warehouses and military camps are concentrated in the inner city, and the official residences and many high-ranking magnates also live in the inner city.

Between the inner city and the outer city, a large number of civilians were concentrated, and in the seventh year of the Great Cause, the army of Laihu'er broke through the outer city, and the military discipline was sloppy, and the soldiers looted the houses on a large scale, before they were defeated by the Goryeo army ambushed in the inner city.

Therefore, for the Sui army, attacking the outer city was only the first step, and the food and materials they needed were concentrated in the inner city, and only by breaking through the inner city could they seize the spoils of war.

Yang Yuanqing immediately looked at the city from a low and high slope, judging from his many years of experience in attacking and defending the city, Pyongyang City is a majestic city, the whole is very strong, almost integrated, it is difficult to have a trick to capture it.

The moat is as wide as two zhang, and there is a protruding horse city built every ten zhang, the suspension bridge is high, and the city gate is strong, it is difficult to use a battering ram to work, and the only way is to climb the city and use a ladder to storm the city.

The key is that the Sui army only has 30,000 troops, and it takes a lot of casualties to capture this city, but these are his elite troops, and he is not willing to suffer too many casualties.

After staring and watching for a moment, Yang Yuanqing had nothing to do for a while, and at this time, the Asian general Shen Guang stepped forward and reported: "Chief, you might as well attack the city at night, it is more effective than attacking the city during the day." ”

One sentence reminded Yang Yuanqing that he ordered the Liaodong Army to send a scout team to infiltrate the city of Pyongyang, I don't know if this scout was successful, if there were really Sui scouts in the city, then they would find a way to get in touch with the Sui army.

Thinking of this, Yang Yuanqing had another glimmer of hope in his heart, and asked Shen Guangdao: "You participated in the attack on Liaodong City back then, how did you capture Liaodong City in the end?" ”

Shen Guang has been serving as a local guard general in Jiangjun, and this time he attacked Goryeo, Yang Yuanqing specially transferred him, because Shen Guang had participated in the Goryeo Campaign on behalf of the Fengzhou Army, and made great contributions in the capture of Liaodong City, and he was very familiar with the situation of the Goryeo Army.

Shen Guang sighed and said: "The biggest characteristic of the Goryeo army is tenacity, the governor must not expect them to surrender, only by killing them, don't think about capturing them, is the right way to attack, and they must not be trusted, their so-called surrender is all false, once the Sui army is fooled, it will be wasted, this lesson was too profound back then." ”

Yang Yuanqing nodded, and immediately ordered: "Order the soldiers to camp three miles away and rest on the spot!" ”

The Sui army did not rush to attack the city, but set up a large camp three miles away from the west city, and the camp tents rose from the ground, and the soldiers buried the pot to cook, recuperate, and waited for the night battle......

Night fighting has always been the traditional strength of the Sui army, everyone in the Central Plains is known, in order to deal with the Sui army, the Tang army and Li Mi Wei army have followed suit and launched night combat training, but the Goryeo army may not know, and they may not be able to defend at night.

Therefore, in the first battle, Yang Yuanqing chose to be at night.

At night, as night fell, the drums in Pyongyang sounded, 'Boom! Boom! Boom! The sound of drums shook the heavens and the earth, and the Sui army threw in 9,000 troops, of which 4,000 besieging soldiers and 5,000 soldiers assisted the defense with bows and arrows, and began the first tentative attack.

Four thousand sword and shield soldiers, holding shields in one hand and war swords in the other, poured up like a tide, and among them were ten siege ladders, marching towards the western city wall.

The Goryeo defenders in the city did not dare to slack off, they had been paying attention to the movements of the Sui army, and when the war drums of the Sui army sounded, the Goryeo army immediately invested 10,000 defenders and 20,000 temporarily armed young men, and intensively deployed at the head of the city.

The siege battle finally broke out, the arrows on the city were like a rain, overwhelmingly shot at the Sui army, and the Sui army's five thousand archers also launched a counterattack, the dense arrow rain shot to the city, the city and the city formed an arrow net, hundreds of Sui army forwards with a three-zhang long plank on their heads, braving the rain of arrows to the city to rush.

They quickly built a makeshift bridge over the moat with thick planks with huge iron nails at both ends that were firmly driven into the earth.

The first ladder was pushed slowly by the soldiers towards the city wall, and the ladder arm turned, 'Boom! With a loud bang, a heavy ladder was set up at the head of the city, and dozens of Sui soldiers rushed up, holding their shields high and rushing towards the head of the city
