I want to know the answer to the following question:
What battle is considered the US's first significant fight in the Korean War?
All the background I'm provided with is that "The Battle of Osan, the first significant American engagement of the Korean War, involved the 540-soldier Task Force Smith, which was a small forward element of the 24th Infantry Division which had been flown in from Japan.". Is that enough to answer the question?
Answer: yes
