Many people often confuse Goguryeo and Goryeo, but in reality these are two different countries. Goguryeo was a multi-ethnic minority country founded in the three eastern provinces and a small half of the peninsula, and its founders were Han Chinese, and that area has always been the territory of the Central Plains Dynasty.

Goryeo, on the other hand, was a country that was established by rebellion on the Korean Peninsula two hundred years after the fall of Goguryeo, and it was only because Goguryeo had ruled that place for a long time that they followed the name of Goguryeo and called themselves Goryeo.

Therefore, most of Goguryeo's land is in the northeast, where the white mountains and black waters are a wild land in the eyes of the Tang people, but in fact it is a rich land. Imagine the great plains of the three eastern provinces in later generations, and you will know that there will be no shortage of food in the black soil rich in humus.

Wu Yuanqing has read the report, Goguryeo has indeed had natural disasters in recent years, floods have occurred in several places, resulting in a reduction in grain production, and even the most serious place has a grain harvest, but there is definitely not too much food shortage, let alone to buy so much grain from Datang back.

Then, Goguryeo is indeed buying a lot of grain now, and it is very interesting.

But in the discovery of Hanjiacang, Wu Yuanqing did not report to Li Shimin, because it was useless to report, it was just a normal grain transaction, or an old grain that Hanjiacang urgently needed to deal with.

What's more, it was Goguryeo that was sold, the titular vassal state of the Tang Dynasty. Over the years, the relationship between the Tang Dynasty and Goguryeo is still okay. After Gao Jianwu ascended the throne, he sent envoys to the Tang Dynasty to ask for canonization, and was allowed, so he had the title of King Rongliu.

And almost every year, envoys were sent to the Tang Dynasty to pay tribute, and during that period of time it can be said that the relationship between the two countries completely came out of the shadow of the Sui Dynasty's three conquests of Goguryeo.

But there is always an end to the honeymoon period, especially when a small country and a widow face a behemoth neighbor, there will always be a kind of persecution paranoia that others want to harm me.

Rongliu Wang Gao Jianwu is like this.

The crack appeared in Zhenguan for five years, and I don't know if it was a dream or I always remembered that the fallen soldiers failed to return to their hometown when the Sui Dynasty conquered Goguryeo. Anyway, in this year, Li Shimin sent the Guangzhou Governor's Mansion Sima Changsun Shi (Goguryeo to collect the bones of the Sui Dynasty and destroy the Jingguan established by Goguryeo.

This is about the relationship between the Sui Dynasty and Goguryeo, as well as the three expeditions of Emperor Yang of the Sui Dynasty to Goguryeo.

During the reign of Emperor Wen of Sui, the king of Goguryeo was canonized by the Sui Dynasty. At that time, Goguryeo and Sui maintained a tense and peaceful relationship.

Goguryeo, like the small states around the Central Plains Dynasty in the past dynasties, would provoke the Sui Dynasty from time to time and attack the northern frontier of the Sui Dynasty on a small scale many times.

In case the Sui Dynasty was angry and conscripted, the king of the Goguryeo Plain "governed the army and accumulated the valley as a strategy to resist", and was ready to meet the Sui Dynasty army at any time.

Emperor Wen of Sui was very dissatisfied with this and wrote to the king of the plain, "The breadth of Liaoshui is like the Yangtze River? The people of Goryeo, how many Chen countries? If I don't have a good education, I will blame the king and order a general, why should I do more! ”

The king of the plains died of illness without any reaction when he received the edict, but the thorn was buried. His successor, Xiao Gui Cao, the king of Yingyang, continued to invade the borders of the Sui Dynasty as usual, and even secretly communicated with the Turks.

After the envoys of the Sui Dynasty met Goguryeo's envoy in the Turks, Emperor Wen of the Sui Dynasty sent a letter to Goguryeo asking Goguryeo to terminate its military alliance with the Turks, stop the continuous invasion of the Sui Dynasty's frontiers for many years, and express submission to the Sui Dynasty. Although the king of Goguryeo Youngyang ostensibly accepted the ultimatum of Emperor Wen of Sui. However, in the second year, he brazenly united with the Yan Ya to preemptively attack the military garrison in western Liaoning, and was counterattacked by Wei, the governor of Yingzhou, and the Sui Dynasty and the opposition were shocked.

Subsequently, Emperor Wen of Sui sent a heavy army to conquer Goguryeo. Yang Liang, the king of Han, and Shiji, the king of Shangzhu, were the marshals of the marching army, and Zhou Luoyu was the chief of the water army, leading an army of 300,000 to attack Goguryeo by land and water, and issued an edict to depose the king of Goryeo, Gao Yuanguanjue.

However, in this expedition, the Sui Dynasty was a loss. During the rainy season, the roads were muddy, the supply of food and grass was not available, there was a lack of food in the army, and there was an epidemic. The waterways encountered strong winds again, and most of the warships sank. Eighty or ninety percent of the 300,000 Sui troops died, and less than 50,000 were able to retire alive.

This time, the army basically withdrew without engaging the battle, but the king of Goguryeo was frightened and sent an envoy to apologize and proclaim himself the dung soil minister of Liaodong.

The face was gained, and as for the loss of the lizi, the Central Plains Dynasty had always cared much about it, so as soon as Goguryeo begged for mercy, Emperor Wen of Sui forgave them and treated them as before.

Then there is the three expeditions of Emperor Yang of Sui to Goguryeo.

In the history books, Emperor Yang of the Sui Dynasty's conquest of Goguryeo was all scolded without exception, and he was reckless and militaristic.

Emperor Yang of Sui's original intentions were good, but he was in a hurry, coupled with bad luck, he recruited more than one million soldiers and more than two million people, and really gathered the strength of one country to attack Goguryeo. However, due to various reasons, the first engagement was because the pontoon bridge was extended to a few meters away from the opposite bank, and was hit by the Goguryeo army in the middle of the battle, and many people died, and even the general Mai Tiecane and Hu Benlang of the Chaozhu State were killed in this first engagement.

Then he finally destroyed the tens of thousands of troops of Goguryeo in the Battle of Dong'an, and took advantage of the victory to surround Liaodong City. Emperor Yang Guang of the Sui Dynasty gave the emperor's order again, making the military order unsmooth and delaying the fighter.

Emperor Yang of Sui said that it is now "hanging the people to fight crimes, not for fame", and ordered his army to be divided into three provinces, but whenever there is an attack on military action, it is necessary to notify each other between the three provinces, and the light army is not allowed to advance alone, and the military advance must first hear Emperor Yang of Sui, and wait for the reply order.

This Nima is in ancient times, not in modern times, and a phone call can convey orders. In ancient times, it was completely dependent on the transmission of people layer by layer, and later generations had telephones, computers, etc., and there would often be delays in fighter planes, not to mention ancient times.

The Goguryeo army in Liaodong City made several sorties, which was not conducive to holding on. Emperor Yang of Sui ordered the siege of the city, and ordered the generals that if Goguryeo wanted to surrender, it should be appeased and accepted, and no more attacks should be made.

It's a complete mess, but the people down there have to carry it out.

Often when the city of Liaodong was about to be attacked, the army in the city shouted surrender, and the generals of the Sui Dynasty did not dare to continue the attack according to the order of Emperor Yang of Sui, but played Emperor Yang of Sui first, and when the reply order arrived, the Goguryeo army in the city had prepared a defense and began to resist again.

It's just once, but this situation has happened many times, and Emperor Yang of Sui is just self-righteous and doesn't feel that he has made a mistake in giving orders. So all the good fighters were squandered and wasted.

There is a saying that God will punish those who waste opportunities.

The morale of the Sui army, which fell again and again, could not defeat Liaodong City, and under the elimination of one and the other, the morale of Goguryeo came up, and luck also came.
