Jing means Gaoqiu is a Guan, a type of Que. He won the battle and set up the Guan, and thought it was a place to hide the corpse, but in fact he showed off his martial arts. Emperor Yang of Sui went east to goguryeo, and all three times ended in failure. Not only did he lose his troops and generals, but he also suffered more than 100,000 people plundered by Goguryeo, as well as the people in the northeast of the Sui Dynasty. Li Shimin, as a witness to these incidents, had a great impact on him.

When Li Shimin was young, he was upright in the heyday of the Sui Dynasty. No one had the intention to rebel in the Sui Dynasty at that time. As a hereditary nobleman and a royal relative, the Li family was once a die-hard supporter of the Great Sui royal family. Li Shimin was also educated as a minister of the Great Sui Dynasty and was loyal to the Emperor of the Sui Dynasty.

The Sui Dynasty would decline in just over ten years, which was inseparable from the eastern expedition of Goguryeo. It can be said that if Emperor Yang Guang of Sui did not expedition of Goguryeo, the Sui Dynasty would never have perished. This is why, when Li Shimin talked about the eastern expedition, all the civil and military officials advised him. A simple reason is that the powerful Sui Dynasty was unable to conquer Goguryeo. Now, the Tang Dynasty, which is in ruins, can defeat Goguryeo?

This is just an ordinary person’s idea, but Li Shimin’s idea is different.

In Li Shimin's consciousness, conquering Goguryeo was not as difficult as imagined. The reason why the Sui Dynasty failed in the conquest was directly related to Emperor Yang of Sui's great joy and arrogance. He didn't need to have much military talent. Anyone who could fight a normal war would not defeat the war that could not lose no matter what.

The dispute between the Sui Dynasty and Goguryeo had a long history. As early as Emperor Wen of Sui, Goguryeo took advantage of the unification of the north and south of the Sui Dynasty and attacked the northeastern border of the Sui Dynasty on a small scale many times. After King Yingyang of Goguryeo succeeded to the throne, the special envoy of the Sui Dynasty met Goguryeo's special envoy in the Turks. Emperor Wen of Sui passed a letter to Goguryeo to terminate the alliance with the Turks, demanding that Goguryeo stop the years of invasion of the Sui border and express submission to the Sui Dynasty. Although Goguryeo's Yingyang King accepted the ultimatum of Emperor Gaozu of Sui on the surface, the next year, King Yingyang joined forces with Sui Mai to attack the Sui Dynasty's Cavalry Mansion in Jizhou Road.

In the 18th year of Kaihuang, Gao Yuan, the King of Yingyang of Goguryeo, "led more than 10,000 cavalry from the Marine Mountain to attack the western part of Liao" and was repelled by the Sui Dynasty. Goguryeo did not surrender, and still refused to obey orders and did not pay tribute.

Emperor Wen of Sui could not bear it anymore, and appointed King Yang Liang and Wang Shiji as the marshal of the army, leading 300,000 land and water to attack Goguryeo, Left Pushe Gao Yang as the chief secretary of the Han Dynasty, and Zhou Luohu as the chief of the navy. However, the conquest was not smooth. Yang Liang encountered heavy rains, transport was not continued, the army lacked food, and he encountered illness. Zhou Luohu went to sea from Donglai and marched towards Pyongyang City, but was exposed to wind in the middle of the journey, and the ships were mostly floating. The Sui army had to return on the water and land, and eight or nine out of ten died.

Seeing that the Sui army was so powerful, King Goguryeo was worried about the second conquest, so he apologized and claimed to be "the Yuan of the Liaodong dirt minister". Seeing that he could not do anything to him, Emperor Wen of Sui had to stop the army and endured it.

But when Emperor Yang of Sui, King Yingyang of Goguryeo carried the Sui Dynasty on his back and sent envoys to secretly communicate with the Turks, wanting to attack the Sui Dynasty on both sides. At that time, Emperor Yang of Sui was on the northern tour and stayed at the Turkic Qimin Khan. The Qimin Khan did not dare to hide it and told Emperor Yang of Sui about the incident.

Emperor Yang of Sui was very angry and asked someone to tell Goguryeo's envoys to come and see him, and let him be a minister and be a minister on time. If he did not blame him, he would treat him equally with the Khan of Qimin. However, King Yingyang of Goguryeo insisted on "not following" Emperor Yang of Sui, so Emperor Yang of Sui began to make up his mind to conquer this neighboring country with a disobedient heart.

In the sixth year of Daye, the Sui Dynasty pacified the Khitan and Tuyuhun and other neighboring countries, and its momentum reached its peak. In addition to Goguryeo, all the neighboring countries expressed their surrender. Goguryeo became the only thorn in the eyes and the thorn in the flesh, and became the biggest stain on Emperor Yang of Sui's civil and military achievements. The conquest of Goguryeo was already an arrow on the string and had to be fired.

Pei Ju, the Huangmen Minister, understood what Emperor Yang of Sui thought and persuaded Emperor Yang of Sui to threaten King Goguryeo to enter the court on the grounds that Goguryeo was originally a place that Jizi had granted, but now he did not obey the etiquette of his ministers. Gao Yuan, the King of Yingyang of Goguryeo, did not obey the etiquette, and gave Emperor Yang of Sui an excuse to conquer Goguryeo. The following year, Emperor Yang of Sui formally issued an edict to conquer Goguryeo and mobilized the whole country to fight to achieve complete success.

It was this idea that ruined the great situation of the Sui Dynasty. Emperor Yang of Sui ordered Yuan Hongsi, the general manager of Youzhou, to build 300 ships to Donglaihaikou. The prescribed date was very tight. In order to complete the task, the officials supervised the shipbuilding craftsmen to work day and night in the water and hardly dared to rest. Because they soaked in the water for a long time, maggots grew from their waists and died countless people. Emperor Yang of Sui also issued an edict to gather the troops and horses of the world, regardless of north and south, and far, to gather in Zhuo County. Not only did the people suffer money, but a large number of soldiers gathered, the chaos was not controlled effectively, and the surrounding people complained.

After gathering the world's army, Emperor Yang of Sui also recruited 10,000 sailors, 30,000 crossbowmen, and 30,000 platoons in Lingnan. He ordered Henan, Huainan and Jiangnan to build 50,000 chariots to Gaoyang to load armor and curtains, and to recruit civilians to supply military supplies. In the autumn of the seventh year of Daye, Emperor Yang of Sui recruited civilians and ships south of Jianghuai and transported Liyang and Luokou Cangmi to Zhuojun. The ships were more than a thousand miles apart, carrying armor and attacking tools. Hundreds of thousands of people were on the road for a long time, crowding the road, day and night, and the dead were sleeping together, and the foul road was filled. Before the war began, Emperor Yang of Sui had already mixed the world with complaints.

In this battle, the Sui army mobilized more than one million main battle soldiers, which was the highest in history. The Tang Dynasty now claims to have millions of soldiers, but in fact, it was not enough. However, even though Emperor Yang of Sui was full of complaints, he actually mobilized so many people. In addition to the civilians who transported food and grass for the army, more than five million people participated in the war directly.

How many people were there in Goguryeo? Five million people participated in the war, and even if one spitted, they could drown the Goguryeo people. In Li Shimin's opinion, this was a war that could not be defeated no matter how hard he fought. Even if he had a dog to command, he could win the war. This was indeed the case, but unfortunately, Emperor Yang of Sui also thought so.

Since I can't lose no matter how hard I fight, why can't I reflect my kingly army and the demeanor of the Celestial Kingdom? So a battle of national destiny became the "hype" of Emperor Yang of Sui's martial arts.

Emperor Yang of Sui decided to lead the army in person!

When Emperor Yang of Sui decided to lead the army in person, the civil and military officials in the court did not object. They also felt that although Emperor Yang of Sui had a little trouble in this battle and had some complaints among the people, a big victory was enough to fill all these complaints. The emperor wanted to show his martial arts and let him show it. So there were flattery words inside and outside the court. Emperor Yang of Sui believed these words and became more and more "slutty".

He divided more than one million troops into three groups, including the left and right. In addition to the central army, the left and right armies divided into twelve groups and set up formations. In order to "dividify military achievements equally", Emperor Yang of Sui assigned tasks for each group, and planned to complete their respective tasks and eventually join Pyongyang after completing their respective tasks.

Before he could fight, he divided his military achievements. How could he not defeat the enemy? At the end of March of the eighth year of Daye, the Sui Dynasty army arrived at the Liaohe River. Emperor Yang of Sui ordered Yuwen Kai to build a floating bridge. After the floating bridge was completed, the Sui army attacked from the west bank. When the floating bridge extended to a position several meters away from the opposite bank, Goguryeo took the opportunity to attack. The Sui army was unable to land and died a lot. Mai Tiezhang, the Zuo Teng Guard General, and Qian Shixiong, and Meng Cha, all died in battle. So the Sui army gathered troops, and the Shaofu Supervisor He Chou connected the bridge. The troops advanced one after another, fought in Dong'an, defeating the Goguryeo army, and tens of thousands of people died.

Although this battle was defeated, it was not damaged. The Sui army took advantage of the victory to encircle Liaodong City.

The most fatal thing is to distribute military achievements in advance. Since the civil and military officials and emperors of the court believed that this battle would be won, they set the tone for this battle from the beginning. Emperor Yang of Sui gave a high-sounding reason, calling it "the slandering the people and attacking crimes is not for fame and fortune." Since it is not for fame, then we cannot seize the merits. In order to prevent the generals from hiding lightly the troops to fight alone to gain merit and reputation, any military advancement must first report Emperor Yang of Sui and wait for the order to reply. This directly led to the great defeat in the battle of siege. The Goguryeo army in Liaodong City did not attack several times, so it turned into a defensive move. Emperor Yang of Sui issued an order to attack the city and ordered the generals to have the spirit of the upper country. If Goguryeo wanted to surrender, it should be appeased and accepted, and no longer allowed troops to attack.

This kind of stupid operation made up for the last piece of the defeated jigsaw puzzle. When Liaodong City was about to be captured, the Goguryeo army in the city claimed to surrender. The Sui generals were ordered by Emperor Yang of Sui and did not dare to continue attacking. According to the previous order, they would ask for any action. They quickly wrote a memorandum to report to Emperor Yang of Sui. After two or three days passed, when Emperor Yang of Sui replied to the order, the Goguryeo army in the city had prepared defense and began to resist again. This situation was repeated many times, and Emperor Yang of Sui still did not wake up. The so-called one-game deterioration and three-ticket depleted. Even if Emperor Yang of Sui woke up and went to the front line to command, the Sui army, whose morale had declined, remained stalemate for another month under the stubborn resistance of the Liaodong defenders, but could not be taken down. Other cities in Goguryeo were similar to those in Liaodong City, but they could not be taken down.

Even if the central army is like this, the attacks from other roads are equally bad.

The water route was led by Lai Hu'er, the general of the Right Guard at that time. The warships were connected for hundreds of miles, and the momentum was huge. Entering the waters, they met the Goguryeo army and easily defeated them. Lai Hu'er wanted to take advantage of the victory to attack the city of Goguryeo. Zhou Fa, the deputy general manager, was worried that he would underestimate the enemy and advance together, so he hoped to advance together after the other Sui troops arrived. Lai Hu'er refused to listen and selected 40,000 elite soldiers and advanced to the city of Goguryeo. Goguryeo pretended to be defeated and Lai Hu'er was trapped. Goguryeo ambush took the opportunity to attack the Sui army. Lai Hu'er was defeated, and only a few thousand soldiers returned.

The Goguryeo army pursued the Sui army shipyard, and Zhou Fashang formed a formation to wait for it. The Goguryeo army retreated. Lai Huer led his army back to Haipu, but failed to complete the established response mission.

On land, there were also many brainless actions. At that time, the army carried the food and grass for hundreds of days, and also carried platoons, guns, spears, clothes, military equipment, and fire curtains. They were too heavy to be loaded. The equipment was too big and obviously not discarded. The soldiers dug pits under the curtain and buried food and grass. As a result, they had only walked halfway and the food and grass were almost exhausted. At this time, Goguryeo sent its minister Yizhi Wende to surrender and observe the reality of the Sui army.

General Yu Zhongwen wanted to take the opportunity to capture Yizhi Wende, but was stopped by Liu Shilong. After Yu Zhongwen let Yizhi Wende go, he regretted it and decided to pursue Yizhi Wende. At that time, Emperor Yang of Sui ordered the garrison to be subject to the Jiedu of Zhongwen. Yu Zhongwen, Yu Wenshu and nine other troops crossed the water to chase Yizhi Wende. Yizhi Wende saw that the soldiers of the Sui army were hungry, so he wanted to make them even more tired. He pretended to be defeated and withdrew every time he fought. Yu Wenshu won seven battles within a day, continued to advance, and crossed the Sashui River. Yizhi Wende sent envoys to surrender again. Yu Wenshu saw that the soldiers of the Sui army were tired and could not fight anymore, and the city of Pyongyang was in a dangerous state, so it was difficult to capture quickly, so he had to retreat.

When the army returned, the Goguryeo army attacked from all sides, and Yuwen Shu and others fought and went on. When they arrived at the Sashui River, when the Sui army crossed the river halfway, Goguryeo attacked the Sui army's rear army. Xin Shixiong, the general of the Zuotun Guard of the Sui Dynasty, was killed in battle. All the Sui army were defeated and could not be forbidden. The soldiers fled for a day and a night to reach Yalu River, and traveled for 450 miles. Wang Rengong was the rear guard of the palace and defeated Goguryeo's pursuers. When crossing the Liaohe River, there were 300,000 troops in this route. When they returned to Liaodong City, there were only less than 3,000 people left. There were a huge number of supplies, weapons and weapons, and they were all lost, and all became Goguryeo's spoils. These supplies also made great efforts to deal with the second conquest.

Unable to achieve the expected victory, domestic conflicts were not exported, and finally broke out. Wang Bo, Dou Zi Huang, Dou Jiande and other people revolt, and countless people captured the cities. Emperor Yang of Sui ordered the commander to know the commander, Ying Yang and the counties to pursue each other, and they were killed when they were captured, but the peasant uprising was still not prohibited. But after all, the lean camel was bigger than a horse, and the peasant uprising was like a stone thrown into the calm lake, but it was not able to cause much storm.

After the Eastern Expedition was setback, Emperor Yang of Sui decided to make a second Eastern Expedition. This Eastern Expedition learned from the last lesson and allowed the generals to "work at a cheap price". The Sui army set up flying buildings, crashed cars, and ladders under the Liaodong city, and dug tunnels to cooperate to attack the city day and night. However, during the last Eastern Expedition, Goguryeo obtained a large amount of equipment from the Sui army, so that both sides were evenly matched and could not fight hard.

Emperor Yang of Sui initiated his ruthlessness and decided to rely on his own advantages to dig soil and bury hills, build mountains on flat ground, and fill the Liaodong city from top to bottom. Although this method was stupid, it was very effective. But when it was about to succeed, there was another problem in the country. This time, it was not ordinary people, but Yang Xuangan, the country of Shangzhu. The world suffered from Emperor Yang of Sui for a long time, and those who had prestige raised their arms and shouted, and responded. Emperor Yang of Sui had to withdraw his troops to suppress the rebellion. The military funds and equipment he left behind were accumulated like hills, camps, tents, and the case was blocked. They were all abandoned, and the victory they saw was gone.

After quelling the rebellion, Emperor Yang of Sui was already full of problems. Emperor Yang of Sui wanted to fight east again and was killed in Jiangdu, which is now Yangzhou City.
