Du He and Wei Chi Baoqi accepted Li Su's instructions and led the Flying Tiger Army to set off first.

Attacking Goguryeo, Li Su was not worried about the combat strength of the Tang army. Li Jing, Wei Chigong, Niu Jinda, Zhang Shigui, who accompanied Li Shimin, and Xue Rengui, who arrived early, were all among the top generals in the Tang Dynasty.

Li Shimin himself is also a top military general in the Tang Dynasty and has rich combat experience. The organizational form, equipment, and training of the Tang army were not something that the Goguryeo people could compete with.

The only thing he was worried about was that Li Shimin was so happy.

The reason why Li Su preemptively proposed to send 300,000 troops was because in history, when Li Shimin first conquered Goguryeo, he only dispatched 100,000 Tang troops, but he was defeated, and he himself was besieged in the city of Shenzhou (Shenyang) and was in danger of accidents.

Li Su originally hoped that Li Shimin would mobilize at least 500,000 people to participate in the war. However, Li Su can no longer advise, Li Shimin is a person who wants to save face.

Li Shimin led the army to the battle.

Li Su was always uneasy and felt that he should do something.

On the third day after they left, Li Su summoned Fang Xuanling, Wei Zheng, and Hou Junji and told them his worries and thoughts.

Wei Zheng was a little skeptical, and Fang Xuanling and Hou Junji were also a little unimpressed. After Li Su's patient persuasion, they finally agreed with Li Su's opinion. Subsequently, Hou Junji was responsible for the implementation.

The Goguryeo people on the east bank of the Liao River found that the Tang army was setting up a wooden platoon on the opposite side and thought that people were about to cross the river and launch an attack. The Goguryeo garrison hurriedly mobilized men and horses to prepare for the Tang army's attack.

At 10 a.m. on October 23, the weather was gloomy, and about 1,500 Tang troops boarded on rafts toward the other side of the river. The river here is about 700 meters wide, and the Tang army is little by little on the other side of the river.

The Goguryeo people waited by the river, and when the Tang army approached the shore, the bows and crossbows were fired together, and for a time the arrows were like locusts.

On each wooden platoon of the Tang army, a tall wooden shield was erected at the front end, and the bows and arrows of the Goguryeo army did not pose much of a threat to the Tang army.

Just when the wooden raft was less than 100 meters from the shore, the Goguryeo stone thrower began to fire. The 30-kilogram stone projectile flew towards the wooden platoon of the Tang army and fell into the river, splashing a huge splash.

The wooden rafts drove in the river, moving slowly, and under the blow of stone bullets, completely resigned to fate, many wooden rafts were hit by stone bullets, and the soldiers fell into the water one after another. Fortunately, they were not swept away by the rushing river and were rescued from the rafts.

Seeing that they were about to reach the shore, a large number of Goguryeo people poured out on the riverbank, with nearly 10,000 people and horses.

The commander of the Tang Army saw that he was such a person, and he was sent to death in the past. So he ordered a reversal and retreated to the other side of the river.

In the next few days, the Tang army built more wooden platoons on the opposite bank, and it seemed that more Tang troops would be transported at one time.

The Goguryeo generals judged that the Tang army was going to cross the river here, so they transferred the surrounding Goguryeo troops, so that the Goguryeo people on the other side of the river reached more than 30,000 people, and prepared to annihilate the Tang army crossing the river here.

On the night of October 25, the river was covered with fog.

Wei Chi Baoqi took 5,000 Flying Tiger soldiers to the wooden platoon, and Du He saw them off by the river.

Du He said: "Baoqi, be careful, if you encounter a Goguryeo, don't fall in love with the war, and quickly retreat to the other side." ”

Wei Chi Baoqi said: "Don't worry, commander, I promise to complete the task." ”

The Flying Tigers set off, and instead of rowing to the opposite bank, they went down the river and disappeared into the night.

Six hours later, Yu Chi Baoqi saw the shadow of a big boat on the river bank in front of him, and he lifted the lantern and shook it. Soon, he saw the lights on the big ship.

Soon, the figure of Xue Rengui appeared on the bow of the ship, and he said, "Commander Wei Chi, I will lead the way in front, and you will follow behind." ”

The great ship sailed to the opposite shore, and the wooden platoons of the army followed.

The river here is 1,300 meters wide, and the wooden rafts of the Flying Tigers are all over the river, and little by little they sail to the opposite bank.

It was almost to the shore, and the big ship could not continue forward. Xue Rengui got off the big boat and came to Yu Chi Baoqi's wooden platoon. After briefly briefing Yu Chi Baoqi on the situation on the other side, he boarded the other side of the river with Yu Chi Baoqi.

Just as the Tang army was on the riverbank, the Goguryeo sentinels had already discovered the Tang army's movements, and they fled while shouting for alarm.

On the other side of the river was a mountainous terrain, which was not suitable for large armies, so the Goguryeo defenders in this area had only a few outposts, and the total strength was less than 100 men. Seeing so many Tang troops coming ashore, they did not dare to fight the Don army and fled in all directions.

The Tang army did not chase either, their goal was Jingguan here.

It turned out that all the actions in the middle reaches of the Liao River were to cover this action to seize the Jingguan. And this plan was explained to Du He and others when the crown prince Li Su was in Chang'an.

Yu Chi Baoqi and Xue Rengui came to the front of Jingguan, knelt on one knee, and said, "Ancestors, we are here to take you home." ”

With the efforts of thousands of Tang troops, all 100,000 Jingguan were loaded onto wooden rafts and loaded onto big ships.

At this time, the sky was bright, and the sentry of the Flying Tiger Army, who was on guard, spotted a group of Goguryeo troops and drove towards here.

The officers and men of the Tang Dynasty, who were full of grief and indignation, all demanded a battle and vented their evil anger. Yu Chi Baoqi exchanged a few words with Xue Rengui and decided to ambush the Goguryeo people.

The Goguryeo army consisted of about 1,000 men, and except for a few officers who were amazed, the rest were infantry. They saw that the Tang army had already mounted the wooden platoon and was retreating, so they rushed to the river and prepared to pursue the Tang army with bows and crossbows.

When they arrived at the river, Yu Chi Baoqi and Xue Rengui each brought 1,000 Flying Tiger troops to cover up.

The Goguryeo army was a local army, and in the face of the powerful Flying Tiger Army, it was slaughtered in less than half an hour.

Just as Yu Chi Baoqi ordered a retreat, a Flying Tiger Army soldier said: "Commander Yu Chi, let's also get a Jingguan for the Goguryeo people to avenge the martyrs." ”

Yu Chi Baoqi and Xue Rengui both agreed with this opinion, so except for the two officers who were left behind in order to understand the situation of the Goguryeo army, the rest of the Goguryeo people were all beheaded, and at a junction in the direction of the Goguryeo army, they were all placed in Jingguan.

On October 27, Li Shimin personally presided over the sacrificial activities to pay tribute to the martyrs of the previous dynasty who fought for the country.

Successfully retrieving the remains of our ancestors is a big deal.

Thirty years ago, Emperor Yang of the Sui Dynasty conquered Goguryeo, killing and injuring millions of people, involving nearly a million families, and the number of their relatives, friends and children was more than millions.

The Tang army recaptured the remains of some of the dead soldiers, and Li Shimin personally paid tribute to their dead souls, which greatly established the image of the Tang Dynasty in the hearts of the people. It also inspired the spirit of the Tang Dynasty to participate in the war, and also had a far-reaching impact on the surrounding countries.

On this day, the king of Silla received Wang Hyunce, an envoy of the Tang Ministry of Foreign Affairs.

Wang Xuance is one of the best people in the history of diplomacy in China and the world.
