Why did Yang Guang fail to levy Korea several times?

Although there are many reasons for the demise of the Sui Dynasty, Yang Di's three expeditions to Korea is definitely one of the most important reasons for the demise of the Sui Dynasty. In the eyes of many people, even in the eyes of Emperor Yang Di at that time, North Korea was not a powerful country, and it was a piece of cake to destroy it. But in the end, Emperor Yang Di failed repeatedly in North Korea, which eventually led to the demise of the Sui Dynasty. From the perspective of strength comparison, South Korea really lags far behind the Sui Dynasty. However, Yang Di repeatedly made mistakes in the process of several expeditions to Korea, and other things interfered, which led to the failure of three expeditions to Korea and eventually lost the entire Sui Dynasty.

Yang Di was very talented, but the three characteristics of North Korea made the Sui Dynasty perish.

After Korea became powerful, it plotted against the Central Plains dynasty. Before the establishment of the Sui Dynasty, there were three regimes on the Korean peninsula: Baekje and Silla, but North Korea was the most powerful, just like Wei in the Three Kingdoms period. But at that time, the territory of South Korea was not limited to the Korean peninsula, but also included a part of the Northeast. At the peak, the territory reaches Liaohe River in the northeast and Hunchun in Jilin Province in the north. At that time, Korea ruled the whole Korean peninsula, while Silla and Baekje lived behind North Korea.

North Korea occupied many places in the northeast of China when it was powerful.

When a country is strong, it will naturally expand abroad, and South Korea is no exception. At that time, North Korea turned its attention to Liaodong in China. After the establishment of the Sui Dynasty, North Korea did not stop. They even colluded with the remnants of the ruined Northern Qi Dynasty and the former Northern Wei Dynasty and invaded the northeast border of the Great Sui Dynasty many times.

However, after the establishment of the Sui Dynasty, it first put down its own civil strife, then went south to destroy Chen, and then mainly fought against Turks, temporarily ignoring the invasion of North Korea in the northeast. Later, after the Sui Dynasty solved various problems, especially after the Sui Dynasty hit the Turks hard, Koryo felt a certain degree of fear, so she once stopped, did not dare to act rashly against the Sui Dynasty, and even sent people to Chang 'an to pay tribute under the strength of the Sui Dynasty.

It's just that although the Central Plains Dynasty was fierce, it was difficult to completely eliminate the nomadic people on the grassland. Therefore, although the Turks apparently surrendered to the Central Plains Dynasty, they secretly had ulterior motives. After seeing this situation, South Korea naturally contacted the Turkic tribes to resist the Sui Dynasty. And because North Korea was far away from the Sui Dynasty, it was bolder than the Turks. Even the Sui Dynasty didn't respond, so they sent troops directly to harass the border of the Sui Dynasty.

Sui Wendi fought Korea in the Sui Wendi era, but failed.

Faced with this problem, Emperor Wendi was furious at that time, so he took Hanwang Yang Liang as the marching marshal and led 300,000 troops to attack North Korea. It's just that the terrain in Liaodong is complex. The Sui army experienced extremely bad weather in Liaodong, and food and grass were not replenished, and many soldiers fell ill one after another. Sui Jun suffered heavy losses before the war and finally had to order its withdrawal. Although Koryo immediately apologized to Emperor Wendi of Sui Dynasty, this unsuccessful March not only failed to stop Koryo, but made Koryo think that the strength of the Sui Dynasty was just that, laying the groundwork for a greater crisis in the Sui Dynasty.

Yang Di's three voyages to the West eventually led to the demise of the Sui Dynasty. After solving other things, Yang Di began to attack North Korea.

In the era of Yang Di, North Korea was indifferent to the Central Plains Dynasty. When Yang Guang ascended the throne, North Korea didn't even have a congratulatory platform. When Emperor Yang Di later visited Turkey, korean king even sent an envoy to secretly contact Turkic Qimin Khan to oppose the tyranny of the Great Sui Dynasty. At that time, Yang Guang, the emperor of Yang Di, was probably quite dissatisfied with North Korea, but Yang Guang didn't make a move at that time because of the crushing defeat in the previous Sui Wendi era. After Emperor Yang Di Yang Guang settled in the surrounding areas, he immediately started the great cause of conquering Korea.

On his first expedition to Korea, Emperor Yang Di attacked Korea with absolute superiority.

In 6 12 AD, the troops and logistics mobilized by Yang Di arrived in Zhuo Jun, the northeast front line, and made the first eastward expedition. When Emperor Yang Di first crusaded, he underestimated his enemies a little too much. At that time, Emperor Yang Di wanted to convince people with good deeds, that is to say, once the Korean people surrendered, Sui Jun could not attack, and those who disobeyed orders were beheaded, and invited envoys and monarchs from neighboring countries to watch Sui Jun attack North Korea. As a result, when the Koreans discovered the mind of Emperor Yang Di, they repeatedly resorted to surrendering and rebelling. The soldiers embedded in the army were afraid of the punishment of Emperor Yang Di, and even though they knew that the Koreans were playing tricks, they did not dare to attack the Koreans, which led to a missed opportunity.

At that time, the terrain in Liaodong was complex and the weather was quite bad, so the time really suitable for attack was not a few months in a year. When the best time passed, Yang Di regretted it, but Sui Jun suffered heavy losses and had to retreat. The first expedition to Korea should be the best preparation. At that time, they were all excellent soldiers who had fought many battles and were the most sure. However, because Yang Di was too proud, the result was a failure.

The second expedition to Korea and the first real Korean fiasco made Emperor Yang Di lose face. When Emperor Yang Di returned to North Korea, he naturally became more and more depressed. After summing up the experience and lessons, Yang Di immediately set out to prepare for the second expedition to North Korea. To be honest, during the second expedition to Korea, Emperor Yang Di did not make any mistakes, nor did he restrain the soldiers at the front line. Moreover, Sui Jun made quite good progress at that time, and soon captured Liaodong City and headed for Pyongyang, the capital of North Korea at that time. At that time, the army of Sui Dynasty was dominant, and the army of North Korea was no match for Sui Jun. If nothing happens, it is only a matter of time before Pyongyang is captured.

Yang Xuangan rebelled in the rear, which led to the failure of recruiting Korea.

However, the accident still happened. Yang Xuangan, who supervised the transportation of grain and grass in Liyang, suddenly launched a mutiny, which was the chief culprit of the failure of Yang Di's second expedition to North Korea. Yang Xuangan was a history of does. At the same time, he also attacked the king of Chu, the son of Su Yang, the king of Yue. He is the first-class son of a wealthy family in North Korea, and his influence in North Korea is intertwined. So when he fought together, many people stood up and echoed him, which had a great shock to the Sui Dynasty. Therefore, the second expedition to Korea had to be terminated, and then Li Zhen suppressed the rebellion in Yang Xuangan. Although the rebellion in Yang Xuangan was quickly suppressed, all the efforts made by Yang Di in the Second Crusade were in vain.

The third expedition to Korea failed twice. In fact, there was a great crisis in the Sui Dynasty at that time, and many people rebelled everywhere, which can be said to be smoke everywhere. If you are more wise, Emperor Yang Di should not go to the East for the third time, but should concentrate on putting down the domestic rebellion, so that the Sui Dynasty should last for some time, and with luck, it may be revived.

The third attack on North Korea was the final blow.

It's a pity that Emperor Yang Di was still too proud, because the previous two defeats against the DPRK made him lose a lot of face in front of the world, especially the leaders of nomadic tribes outside the Great Wall, who were probably watching the jokes of Emperor Yang Di. With this in mind, Yang Di couldn't stand it, and despite the dissuasion of ministers, he insisted on attacking North Korea for the third time. I can only say that the life before Emperor Yang Di was too smooth. He was born with a golden key since he was a child and has never met with setbacks. In fact, the failure to attack Korea was very heavy for the Sui Dynasty, but it could not shake the foundation of the Sui Dynasty. At this time, Emperor Yang Di realized this cowardice, and the Sui Dynasty might be saved. However, Emperor Yang Di insisted on the third Crusade, which can only say that Emperor Yang Di took another step on the road to death.

Due to the previous two fiasco, coupled with the instability of the domestic political situation in the Sui Dynasty, the troops, food and other materials that Yang Di could requisition for the third eastward expedition were far less than the previous two. Even so, the army of Sui Dynasty fought bravely and defeated the army of North Korea many times. If the domestic political situation can be as stable as before, it will not be a problem to destroy Korea. Unfortunately, when Emperor Yang Di started the war, the country was already unstable and there were many rebels. When the army arrived in North Korea, China was already filled with smoke, and Yang Di had to stop the third Crusade.

The Three Signs of Korea and the Lessons from the Death of Sui Dynasty. Before attacking Korea, the Sui Dynasty was very powerful, no worse than the Tang Dynasty. It can be said that Emperor Yang Di Yang Guang is holding a good hand. If there is no accident, after defeating North Korea, the career of Yang Di and Sui Dynasty can be said to have reached its peak. However, Yang Di, once invincible in the surrounding areas, suffered three consecutive defeats in the small country of North Korea, which plunged not only bring disgrace to oneself but also the Sui Dynasty into a greater crisis and eventually led to its demise. There are many reasons for Yang Di's failure in Korea.

Three signs of Korea, ordinary people can't live, and many people rise up to rebel.

In fact, Yang Di's failure in attacking North Korea was not due to the lack of troops and grain and grass reserves in the Sui Dynasty. With the accumulation of grain weapons and military power in the Sui Dynasty at that time, there was no problem at all. But on the way to North Korea, the transportation of grain and grass is very inconvenient. At that time, there was no decent highway from Zhuo Jun to Liaodong in the northeast of China. Troops transporting grain, grass and weapons can only make repairs all the way to ensure the transportation of grain, grass and munitions. Once it rains, the road is muddy and it is impossible to move forward. All these put a lot of pressure on the people at that time, so that many people rebelled because the government's extortion was unbearable. At that time, the generals of the Sui Dynasty also saw this situation and came up with a way to let the soldiers carry 100 days of grain and grass. /kloc-there is too much food and grass in 0/00 day, and the soldiers can't transport it at all, so there are policies from above and countermeasures from below. Many soldiers simply find a place to bury a lot of food and go into battle in their own clothes. Because everyone thinks there is too much food and grass in 100 day, it is estimated that South Korea will soon be laid down. During this period, as long as others bring enough food and grass, everyone will naturally have food. Who knew that the situation of the war was not as smooth as everyone thought, and as a result, everyone had no food later. Once there was no food and grass in ancient wars, it would be fatal.
