Issues of the First Battle of Goguryeo

In the first battle of Goguryeo, the Sui Dynasty had millions of soldiers, and the whole country of Goguryeo fought.

When the Sui army attacked Liaodong City, Yang Guang ordered the generals to appease and accept Goguryeo if it surrendered, and not to attack again. This situation was repeated many times, but Yang Guang remained stubborn.

During this bizarre confrontation and battle, Goguryeo continued to increase its troops. The fact that Goguryeo's internal forces were empty was also one of the reasons why the naval division of Laihu'er was able to easily land and fight to Pyongyang City. However, Lai Hu'er was careless and underestimated the enemy. Not only did he return in defeat, he also lost the supplies of the land troops, and finally escaped back desperately.

Just before Lai Huer arrived at his destination, Yang Guang continued to defend the city outside and inside Liaodong City. He sent another nine armies with a total of 305,000 troops to march directly to Pingyang. However, these nine armies arrived near Pyongyang. They were already exhausted, and their fighting spirit was low. In addition, they were defeated first by the guards, lost food and supplies, and siege equipment. Pyongyang was too dangerous and difficult to attack. After Yu Wenshu and others won the battle, they had no choice but to give up and lead the Sui army, whose morale had recovered a little, to retreat. Unexpectedly, during the retreat, they fell into Ulji Mundeok's flooding plan, turning the orderly retreat into a rout. When they returned to Liaodong City, the Sui army only had more than 2,700 people.

The first battle to attack Goguryeo ended in failure.

doubt? ?

Could Yang Guang's stubbornness be a tactic to lure the snake out of its hole? Could it be that he planned to drag the main force of Goguryeo behind Liaodong City and let the Nine Route Army and Lai Hu'er attack Huanglong together?

If Lai Huer had not acted without authorization, would the outcome have been different?

Personally, I think the above questions are quite interesting and meaningful topics. If any friends are interested in this, you can write a paper and share it!
