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) Harold Thomas Clark, United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving while serving with the United States Military Advisory Group, Korea, deployed as Advisor to 16th Republic of Korea Regiment. Second Lieutenant Clark distinguished himself by extraordinary heroism in action against enemy aggressor forces near Yongchon, Korea, on 5 and 6 September 1950. At 0330 hours on 5 September 1950, an enemy attack spearheaded by tanks penetrated the defense line of the 16th Republic of Korea Regiment, forcing them to withdraw. Lieutenant Clark organized the engineers into a holding force to cover the withdrawal of friendly troops and repeatedly exposed himself to automatic-weapons and small-arms fire in coordinating the fire and movement of the holding force. At 0900 hours the regiment was again attacked by a numerically superior enemy force and became disorganized. At this point, he manned a vehicular mounted .50 caliber machine-gun, ordered the driver to proceed down the road toward the enemy, and personally launched a one-man counterattack. With complete disregard for his own safety, Lieutenant Clark moved forward under heavy mortar, automatic, and small-arms fire and engaged the enemy with withering counter-fire. Inspired by his intrepid actions, the Korean officers and men quickly rallied and joined him the counterattack, driving forward 6,000 yards and inflicting heavy casualties on the enemy. At 1000 hours on 6 September 1950, an American convoy passing through enemy infested territory was stopped by heavy anti-tank, mortar, machine-gun, and rifle fire. The firing attracted the attention of Lieutenant Clark, who fearlessly proceeded into the area under heavy enemy fire to assist the convoy. He directed the men to cover, organized them, and then directed counter-fire on the enemy positions. He repeatedly exposed himself to the intense enemy fire while directing this defensive action, and aggressively engaged the enemy until assistance arrived and the enemy was dispersed. The extraordinary heroism displayed by Second Lieutenant Clark on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
