Throughout the Korean War, there were about seventy three battles and operations that were conducted by both South and North Korea. Just a week after the official invasion of South Korea, the Battle of Andong took place in South Korea. The North Koreans lost about six hundred troops and eleven tanks, which resulted in a South Korean victory. The North Korean twelfth division took on this war, but failed as they couldn’t bring down South Koreans in Andong. About a month after this battle, it was the Battle of Battle Mountain. This involved the United Nations, which were United States and South Korea against the North Korean Army. The strong United States Army, managed to kill eight thousand North Korean troops, while only losing four hundred of their own.
From November of 1950 to December of 1950, the Battle of Chosin took place in North Korea. This was a large operation and had three American Army commanders as part of their group. China was brought into the picture in late 1950, and they joined North Korea on the battlefield. America really had no say in this and they took on China and North Korea in the Battle of Bloody Ridge. During the battle which happened in South Korea, the United Nations which was now composed of United States, South Korea and Philippines took home the win. Fifteen thousand were wounded on the Northern side of the war, while only three thousand were wounded in the South.
The following year, more allies joined forces with the United States, such as France. France and the other nations helped in 1950 at the Battle of Heartbreak Ridge in South Korea. With such a strong army, the United States won the battle once again. The Battle of Kapyong in 1951 had Canada, United Kingdom and New Zealand apart of it. As the South Korean army was getting stronger with higher levels of military support, North Korea and China were very limited in terms of the overall power they had. Soon enough, there was less North Korean activity in the wars and more fighting from the Chinese. In 1953, the Battle of Old Baldy was between China and the United States, Colombia and South Korea.
As you can see, the United States had a great level of involvement in the Korean War, and they took on much of the battles. Throughout the war, several nations came in for some battles and left for the others. This was due to financial and social reasons. The Netherlands came into the Korean War in 1950, but were not participating in all the battles.
