Significance

Operation Pokpoong was the North Korean invasion that triggered the Korean War. Launched without a declaration of war at 04:00 on 25 June 1950, North Korean forces crossed the 38th parallel and drove rapidly into South Korea. Within a week, they had encircled and captured Seoul, the South Korean capital. The operation opened the conflict that would define the peninsula's division and draw in international intervention. North Korea committed 198,380 troops against a South Korean force of 105,752, and the speed and weight of the assault immediately placed the Republic of Korea on the defensive.

Tactics

North Korean forces employed a -style offensive, crossing the 38th parallel and moving swiftly to encircle Seoul. The attack was timed for the early morning hours and aimed at the South Korean capital before a coherent defense could be organized.
