The story of Goguryeo as a history of war against the Sui or Tang Dynasty of Goguryeo.

 1. War with the Sui Dynasty.

- The first round of the master's war.

In 598, Yangyang led 300,000 troops and invaded the Yotaek. In fact, it is recorded that he died of the plague, but unless he is attacked by Goguryeo troops, 80% out of 100% is not thought to have died of the plague. If so, was the first war of masters attacked by Goguryeo troops? It's hard to find actual records, but the logic of the military law, the war.I think it is hidden in the Spring and Autumn Writing Act that 10% and 80% die of plague.

 

- The 2nd Master's War

In fact, the war, which can be thought of as the prelude to the war between Goguryeo and the Su Dynasty, was when the Su Dynasty led the great army and invaded Goguryeo again. This war, which took place in 612, was one of the wars that caused too much effort to build justifications, and the reason the foster system invaded Goguryeo was because Goguryeo envoys were dispatched to their allies, the "Dolgwol." At the same time, he threatens to destroy your country if you don't join the Goguryeo envoy immediately, and the Goguryeo envoy will return. So, the unrelieved foster system finally began the war in 612, led a total of 1,133,800 troops in the 12th Army of the left army, the 6th Army of the 12th Army of the right army, to Beijing and Liaodong, and it is estimated that the supply unit is close to 3 million.

 

 The reason for the defeat of the Sui Dynasty in the Second Master's War.

1. The reason for the defeat of the Sui Dynasty was the problem with the supply line, which was too long. Before departing from Beijing, King Yeongyang attacked Joyang with 10,000 soldiers, and as he attacked Joyang, the Su Dynasty will deploy the supply base to the rear. This is the first cause of defeat.

2. It can be cited as a strategic attachment, and long-distance marches must have a long supply line. Goguryeo actually cut off the supply line of the Su Dynasty troops pushed back to the red camp and cut off the rear supply. For example, when Jojo and Element fought in Kwando Daejeon, the 70,000-member Jojo was able to beat Oso, a military reserve area, because if they cut off the transfer, the troops cannot move and do their best. If it weren't for this red envelope, I wasn't sure how the cilantro war would have changed.

3. In particular, all the right to attack was not for the general general, but for the foster system. All attack commands were reported by the foster agent and then ordered to attack, giving Goguryeo time to reorganize the battle line. This is a clear record in the feed. A soldier from the Su Dynasty, who was attacking Yodongseong Fortress from the front, came and reported it to Yangje again and told the general, and the general attacked Yangje as he told him. This is also one of the reasons for the defeat of several countries because it is the lowest in terms of war and the command system is quite incomplete.

4. I think Goguryeo's defense line had the greatest defense effect. There were a total of four lines of defense, and the first line was the line of defense that stretched around the back of the house. Passing through this swamp, it is intercepted and attacked by countless castles of Goguryeo, and it is engaged in a guerrilla war to attract the Su Dynasty troops to Yodongseong Fortress. When we arrived at the locality near Yodong, the second line of defense, we carried out a tactic to finish by making us tired of Suseongjeon. In particular, he used "Cheongya tactics" to prevent local procurement, and he was exhausted, and he was struggling with the inducement of Goguryeo's defense line.

* What's the night and night tactic?

- This tactic is a consumption tactic, in which when a war breaks out, people living outside the castle burn houses and fields, collect grains and livestock into the castle, and conduct a sit-in war, which is one of the pillars of Goguryeo's collapse in 668. This is because Goguryeo always adhered to Cheongya tactics.

- Goguryeo naval forces vs Sunara naval forces.

One of the controversial reasons for this is whether Goguryeo operated the naval forces at the time, but I personally think it was operated. That's because the base of the naval forces was the end of the Great Wall of China. At that time, the Su Dynasty was not just a million troops in the army, but also a huge army in the naval forces. It is estimated that 100,000 naval forces started from Raeju, Shandong Peninsula, and led by Naehoa, but only 40,000 troops actually fought. Then, how did Goguryeo win in the naval forces?

- Ko Geon-mu (King Yeongryu), who predicted fog in the Battle of Jangsagot, lured 11 ships, fought the first leg of the battle at Jangsigot, and intentionally dragged them to Pyongyang to exterminate 40,000 naval forces. You can assume that.

- Byeoldong University 300,000 vs Eulji Mundeok.

There are many people who know that Eulji Mundeok destroyed Byeoldongdae in Salsu by hand, but there were no handcrafted measures in the records of the time. The handicraft was raised by Danjae Shin Chae-ho, who wrote the Joseon Commercial High School, studying how he won behind the great victory and claiming that he would have won like this with speculation. Suyangje is in a hurry and reorganizes 300,000 troops to advance the army into Goguryeo's Pyongyang Castle, and sends Umunsul and Umungmun to Jangsu. There are several reasons why you have a great power attachment here.

1. Navy general Nae Ho-ah was smashed by Ko Gun-moo while pushing ahead without consent from the army because he coveted his own major.

2. As the supply became unstable, the Sui army, which judged that there was something to eat if they went to Pyongyang, became anxious when there was nothing to eat even if they advanced to Pyongyang, and to make matters worse, they were already exhausted when Goguryeo troops engaged in guerrilla battles.

At this time, General Eulji Mundeok falsely surrendered to the Su Dynasty camp, looked at the camp, and left "Yeosu Jangwoo Jungmunsi," which is said as follows.

" "The mysterious scheme came to heaven."

" "Mysterious tactics are that I've mastered geography."

" "We're already fighting. The ball was high."

" "How can you stop thinking it's enough?"

Ordinary people think that Woo Joong-mun and Woo Mun-sul retreated immediately after hearing this poem, but it's never the time. He advanced to catch Eulji Mundeok, but when he couldn't catch it, he retreated with a justification for this poem.

However, the Su Dynasty's army, which was exhausted from retreat, had already been scattered as it was retreating, and was struggling with "dust."

* What is dust?

- As an ancient military advance, it maintains a square line, and moves in all directions, wary of units transporting supplies and food in the middle.

At this time, when about half of the time came to the slaughter, Goguryeo troops were dispatched to destroy the camp and attack, killing General Shin Se-woong and Maccheoljang to win a great victory.

The 2,700 people who barely passed away and Umunsul were severely reprimanded by the foster agent and tied to an iron chain and retreated as if running away.
