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 Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Service Cross to Colonel (Infantry) Edwin John Messinger (ASN: 0-18503), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as Commanding Officer of the 9th Infantry Regiment, 2d Infantry Division. Colonel Messinger distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Hangye, Hasolschi, and Sabanggarri, Korea, during the period 17 through 24 May 1951. When an enemy force, consisting of 12 divisions, attacked the 2d Infantry Division’s defensive positions in a massive offensive, Colonel Messinger fearlessly and aggressively led his regiment to secure a defensive position assigned to it. Under his daring and skillful leadership, the regiment successfully repelled the attack of two enemy divisions and nearly annihilated the enemy force. Colonel Messinger aggressively moved over difficult terrain, under intense enemy automatic-weapons and mortar fire, to direct personally both the defensive and offensive action of his unit. The indomitable courage, outstanding tactical ability and inspiring leadership of Colonel Messinger were responsible for the tremendous casualties suffered by the enemy and the complete failure of the hostile attack. The extraordinary heroism displayed by Colonel Messinger on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
