The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Second Lieutenant (Infantry) James Howell Mapp, United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while attached to the Liaison Detachment, Far East Command. Second Lieutenant Mapp distinguished himself by extraordinary heroism in action against enemy aggressor forces in the Republic of Korea on 1 and 2 June 1952. On that date, Lieutenant Mapp was a member of a two-man reconnaissance patrol committed effect a daring amphibious maneuver, investigate a reported radar station, and seize enemy personnel for interrogation. While effecting the capture of a Chinese sentry, an outcry from the prisoner alerted the hostile force who immediately opened fire with small arms and automatic weapons from well dug-in positions to the northeast and southeast of the patrol, blocking the route of withdrawal. Realizing the success of the mission was imperiled, Lieutenant Mapp charged the position nearest him and, lobbing grenades with deadly accuracy, destroyed the weapon and its crew. He courageously moved toward the second position, but was ordered to withdraw with the captive soldier to the safety of the beach. The extraordinary heroism displayed by Second Lieutenant Mapp on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
