Today, I went to War Memorial of Korea.

I learned about many various wars.

And I learned about the three kingdom: Goguryeo, Backjae, and Shilla.

Shilla unified all of the country with the China.

I think it is not an unified Korean peninsula because the China helped them.

If China didn't help them, we can't know the future.

Anyway, the most war I impressed was the Salsu river war.

I think it is impressive because many soldiers were died because of just a river.

But, there was the strategy of general Uljimunduck, supporting that accident.

His strategy was to decoy the Sui China's armies.

He retreated on the purpose.

After he decoyed them into Salsu river, the Uljimunduck's army opened the dam.

And there were 300,000 armies before, but the 2,700 armies were left.

I think if there was no Uljimunduck's brilliant strategy, our peninsula will be destroyed by Sui China.

So, I studied about why the Sui China lose, even though there were many armies than Goguryeo.

The Sui China lose because of Sui China's emperor's thought.

He thought that he will win and sent many armies, and of the Goguryeo's strong armies.

So I think it is the biggest battle in Korea.

Thank you for listening to my essay.
