Battle of Pusan Perimeter logistics

Logistics in the Battle of Pusan Perimeter (August 4 – September 15, 1950) during the Korean War played a decisive role in the battle. Efficient logistics, the management of personnel and materiel, supported United Nations (UN) supply lines while the North Koreans' routes of supply were steadily reduced and cut off. UN logistics improved throughout the Battle of Inchon and the defeat of the North Korean army at Pusan.

UN forces, consisting primarily of troops from the Republic of Korea (ROK), the United States (US), and United Kingdom (UK), enjoyed overwhelming air and sea superiority during the battle. The UN efficiently procured and transported supplies from a large stockpile of materiel in nearby Japan.

In contrast, North Korean logistics were hampered by UN interdiction campaigns which slowed the flow of supplies from North Korea to the battle. Though supported logistically by the Soviet Union and China during the battle, North Koreans often had difficulties getting their supplies from depots to the front lines, leaving North Korean troops unsupported during several crucial engagements.

On the night of June 25, 1950, ten divisions of North Koreas Korean People's Army (KPA) launched a full-scale invasion on 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 complete rout. The smaller South Korean army suffered from widespread lack of organization and equipment, and it was unprepared for war. 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. By June 28, the North Koreans had captured South Korea's capital of Seoul, forcing the government and its shattered army to retreat further south.
