As the North Korean People's Army launched a major offensive against South Korea, the situation in the capital city of Seoul became desperate. The South Korean military was grappling with a substantial influx of refugees, many of whom were fleeing the advancing North Korean forces. These civilians added to the chaos and confusion, leading to a critical shortage of resources and a complete breakdown of order in the city. In an effort to slow down the Northern advance, South Korean commanders made the difficult decision to blow up the Hangang Bridge, a vital transportation link over the Han River. This bridge was essential for the movement of troops and supplies, and its destruction was a tactical measure aimed at hindering North Korean forces from rapidly advancing into the heart of the capital.

As South Korean troops initiated the detonation, they understood that they were essentially sacrificing the city in a last-ditch effort to regroup and delay the enemy. Meanwhile, the 5th Division, which had been stationed in or around Seoul, found itself stranded as the situation deteriorated. The destruction of the bridge did not stop the North Koreans, who continued their assault with formidable strength. By the end of the day, despite the valiant efforts of South Korean defenders, North Korean forces successfully entered Seoul, marking a significant turning point in the early stages of the Korean War.
