Battle of Kyongju
The Battle of Kyongju was an engagement between United Nations (UN) and North Korean (NK) forces early in the Korean War from August 31 to September 15, 1950, in the vicinity of Kyongju in South Korea. It was a part of the Battle of Pusan Perimeter, and was one of several large engagements fought simultaneously. The battle ended in a victory for the United Nations after large numbers of United States (US) and Republic of Korea (ROK) troops repelled a strong North Korean attack.
Battle of Chungju
There are records in a book by Luis Frois, but he is not seen war. It is imagined, only just heard from someone else. In his writings, Konishi Yukinaga defeated 80,000 Korean 
and 8000 cavalry and the ax-wielding knight. However, whether this claim is true or not, remains uncertain.
