On 25 June 1950, Korean People's Army (KPA) forces crossed the 38th parallel and invaded South Korea. The KPA utilized a blitzkrieg style invasion using T-34 tanks supported by artillery. The Republic of Korea Army (ROKA) had no methods in stopping the onslaught of tanks as they lacked anti-tank weapons and had no tanks at all.

On 28 June the ROKA demolished the bridge across the Han River trapping soldiers from the 5th Division and killing hundreds of refugees evacuating the city.^[1] North Korean forces were able to cross the river later that day and occupy Seoul.^[2]

On 30 June President of the United States Harry S. Truman released a statement that indicated the invasion of South Korea had grown the threat of communism to the Pacific area and the United States. In response to the invasion, Truman ordered United States provide assistance with air and land forces in Korea. Moreover, Truman ordered the United States Seventh Fleet to prevent any attack on Formosa and strengthened the United States forces in the Philippines.^[3]

As a result of North Korea’s invasion, the United Nations Security Council (UNSC) passed United Nations Security Council Resolution 84.
