The Battle of Osan was the first engagement between United States and North Korean forces during the Korean War, on July 5, 1950. A U.S. task force of 400 infantry supported by an artillery battery was moved to Osan, south of the South Korean capital Seoul, and ordered to fight as a rearguard to delay advancing North Korean forces while additional U.S. forces arrived in-country to form a defensive line. The task force lacked both anti-tank guns and effective infantry anti-tank weapons. Aside from a limited number of HEAT shells for the unit's 105-mm howitzers, crew-served weapons capable of defeating the T-34 had not been distributed to U.S. Army forces in Korea at the time. In the first encounter, a North Korean tank column overran the task force and continued its advance south. After the column had successfully breached American lines, the task force opened fire on a force of some 5,000 North Korean infantry approaching its position, temporarily holding up the North Korean advance. Eventually, North Korean troops overwhelmed American positions, and the remnants of the task force retreated in disorder. (more...)
