On the night of 25 June 1950, ten divisions of the North Korean People's Army launched a full-scale invasion of the nation's neighbor to the south, the Republic of Korea. The force of 89,000 men moved in six columns, catching the Republic of Korea Army by surprise, resulting in a rout. The smaller South Korean army suffered from widespread lack of organization and equipment, and was unprepared for war. The numerically superior North Korean forces destroyed isolated resistance from the 38,000 South Korean soldiers on the front before it began moving steadily south. Most of South Korea's forces retreated in the face of the invasion. The North Koreans were well on their way to South Korea's capital of Seoul within hours, forcing the government and its shattered army to retreat farther south.
