The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pleasure in presenting a Second Bronze Oak Leaf Cluster in lieu of a Third Award of the Distinguished Service Cross to Colonel (Infantry) Arthur Seymour Champeny (ASN: 0-8264), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as Commanding Officer, 24th Infantry Regiment, 25th Infantry Division. Colonel Champeny distinguished himself by extraordinary heroism in action against enemy aggressor forces near Haman, Korea, on 5 September 1950. Colonel Champeny came under direct attack by a numerically superior enemy force which had broken through the Regimental Sector. Confusion developed throughout the area and in the burning village where the Regimental Command Post was located. Small enemy groups had infiltrated the village. Colonel Champeny calmly directed and supervised the withdrawal of his depleted Regiment and the Regimental Command Post. When the new Regimental Command Post had been established, Colonel Champeny returned to reorganize battered elements of the Regiment. He came under fire and was wounded twice. Although severely wounded, he gave instructions for organizing the new defensive positions and transmitted the plans to Division Headquarters. His military poise and battle courage inspired the regiment to withstand the assault. The extraordinary heroism displayed by Colonel Champeny on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
