At 4 a.m., June 25, 1950, North Korean forces, without any provocation by the South, launched an all-out attack, with field artillery and mortar shelling, on South Korea across the entire region around the 38th parallel in drizzling rain and fog and started a carefully preplanned surprise attack. By evening of the same day, North Koreans advanced from 20 to 40 kilometers on all fronts, and it took mere three days to occupy Seoul--the capital.

The Korean War was the first war waged to restore peace under the single flag of the UN.
