When the large group arrived at the west bank of Liaoshui, there were not as many people as when they first set out, and soldiers sneaked away on the way. The naval fleet boarded the west coast of Pyongyang and prepared to attack Pyongyang. In fact, the soldiers in Sui Jun have no fighting spirit. If North Korean soldiers still fight Sui Jun bravely as they did in the previous two times, they are likely to win again. But after two wars, South Korean ministers refused to fight again, and most of them demanded peace. King Koryo agreed with most people and escorted Yang Di, the Sui general and assistant minister of the Ministry of War who had fled to Koryo before, across the Liaohe River to see the emperor, expressing his willingness to surrender.
Yang Guang is very happy, because he is not sure whether he can win the battle, and he is more afraid of failing again for the third time. Now peace in North Korea is exactly what he wants, that is to say, he won and saved the face that he has lost twice. So he ordered the withdrawal and returned to North Korea.
On the way to Banshi, Yang Guang asked the soldiers to sing a song of triumph. Instead of sitting in a chariot, he rode on a burly horse, looking radiant and arrogant. Unexpectedly, when the army came to Handan, a group of peasant troops were killed in one fell swoop, and Yang Gongqing, led by Yang Gongqing, took the lead in pouncing on Yang Guang. Yang guang was surprised. Thanks to the protection of brave guards, he saved his life. Yang Gongqing and a group of rebels robbed more than 40 good horses and ran away. Yang guang lost his prestige, climbed down from his horse and got into the chariot, afraid to show up.
In October, Yang Guang returned to Chang 'an, executed the traitor Hu Sizheng he brought back, and then sent the envoys of North Korea back to take a message that Emperor Yangdi announced that King Koryo would come to North Korea, of course, to show his prestige. However, korean king refused to buy his account and go, which made Yang Guang lose face again and ordered him to prepare for the fourth expedition to North Korea.
Afterwards, Yang Guang calmly thought about it. It was winter and Liaodong was very cold, so he decided to postpone the dispute until next year.
During this period, peasant insurgents surged everywhere, but ministers knew that Yang Guang would rather hear good news than bad news, so no one reported any news about the rebels. Yang Guang believes that the world is peaceful and he can enjoy it to the fullest. Chang 'an got tired of life and moved to Luoyang. The following summer, Yang Guang led officials to the north for the summer.
Yang Guang built palaces everywhere, with concubines, maids and eunuchs. They first came to Jin Yanggong, Taiyuan County, where two nobles waited for many years before meeting the emperor. Yang Guang lived here for a few days and felt that Taiyuan was not cool. He continued to go north and came to Fenyang Palace (Shanxi Yangqu). The temperature here is cool, suitable for summer, but the palace is small, and officials and soldiers can't live there, so they have to build a straw shed in the wild valley, but Yang Guang cares about cooling himself.
In autumn, Yang Guang had a whim to see the frontier fortress. On this day, Yang Guang and his party crossed Yanmenguan (now Daixian County, Shanxi Province) and went north to enter the pastoral area. They want to enjoy the grassland scenery. Two fast horses galloping in the distance came to Yang Guang in the blink of an eye. A man dressed as a Turk jumped off the horse and submitted a secret letter to Yang Guang.
Yang Guang opened the letter and saw that it was written by Princess Yicheng. Princess Yicheng is the daughter of Emperor Wen of Sui Dynasty. At that time, Emperor Wendi Sui Wendi betrothed her to Qimin Khan, the leader of the Turks, and married her. Five years later, Qimin Khan died, and his son Duji ascended the throne, calling him Khan from the beginning. According to custom, Princess Yicheng became Khan's wife from the beginning. In this way, Yang Guang and Turkish leaders began to have a relationship with Khan. However, Yang Guang made much ado about nothing and encouraged Khan's younger brother Chiji not to fight with his brother. Ji Ji didn't tell her brother that Khan was furious at first, so he cut off contacts with the Sui Dynasty.
Khan heard that Yang Guang only brought twenty thousand guards, so he called hundreds of thousands of soldiers and horses to attack Yang Di. Princess Yicheng was worried that the Sui Dynasty would suffer if she didn't guard against it, so she wrote a letter to inform her.
When Yang Guang read Princess Yicheng's letter, he was very scared, so he ran back immediately. As soon as he entered Yanmenguan, Khan led the Turkish army to follow. The Turkish army is all cavalry, marching fast, and smoke is rolling in, and the town of Yanmenguan is surrounded in a blink of an eye.
Yang Guang climbed the North Tower with trepidation to see the enemy. There are so many Turkish cavalry, he can't see the side at a glance, and he is sweating with fear. At this time, Turkish soldiers shot arrows at the tower together, and an arrow hit the crown on Yang Guang's head, which made him plop to the ground and burst into tears. Yang guang cried enough to remember to convene ministers to discuss the withdrawal plan. Some people suggested that the emperor take 3000 cavalry to break through, but most people opposed it. They think it is very dangerous for 3000 cavalry to break through hundreds of thousands of troops. They should send troops to rescue in all directions, and then send people to Turkey to ask Princess Yicheng for help.
Yang guang adopted the latter opinion, and then personally made a wish to the soldiers guarding the city, so long as they kept the city, they would no longer levy Liao and retire. The soldiers mustered up their courage, went wave after wave and persisted in fighting.
Jin Hedong made Li Yuan receive a rescue letter from the emperor and sent his second son Li Shimin to Yanmenguan with 1000 Qin Bing.
When Li Shimin passed Wutai Mountain, he found an army of Sui Dynasty stationed here. It turned out to be 20,000 rescue troops led by General Yun Dingxing of Tunwei. Seeing that there are too many Turks to fight, I will wait here for other reinforcements. Although Li Shimin is only 65,438+08 years old, he is very clever. He said to Yun Dingxing: "Turkic Khan only dared to send troops to attack Emperor Yangdi because our army was far away from Yanmenguan. If reinforcements arrive, our army will be in danger in Yanmen. It is better to confuse the enemy with bluffing. During the day, dozens of mountains and forests are covered with banners, and at night, cymbals (bronze percussion instruments for marching) resound in the distance. The Turks mistakenly thought that my reinforcements would gather and they would retreat on their own. "
Yun Dingxing thought it was a good plan and immediately raised the flag. In just three days, the flag of Sui Jun fluttered at the foot of Wutai Mountain, and gongs and drums were loud at night. When Khan really thought that there were a large number of reinforcements in the Sui Dynasty, he felt guilty. Princess Yicheng also sent someone to report to Khan that there was an emergency war in Turkey and asked him to return immediately. So I withdrew my troops and left.
Yang Di finally turned the corner and hurried back to Luoyang, but the promise of rewarding soldiers guarding the city has been forgotten without a trace, and Li Shimin's great contribution has not been rewarded.
