During the latter part of March 1952, the 1st Marine Division, a component of the U.S. Eighth Army in Korea (EUSAK), pulled out of its positions astride the Soyang River in east-central Korea and moved to the far western part of the country in the I Corps sector. There the Marines took over the EUSAK left flank, guarding the most likely enemy approaches to the South Korean capital city, Seoul, and improving the ground defense in their sector to comply with the strict requirements which the division commander, Major General John T. Selden, had set down. Except for a brief period in reserve, the Marine division would remain in the Korean front lines until a cease-fire agreement in July 1953 ended active hostilities.
