The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to First Lieutenant (Infantry) John Henry Dunn (ASN: 0-1297335), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with Company A, 1st Battalion, 9th Infantry Regiment, 2d Infantry Division. First Lieutenant Dunn distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Kobangsa-ni, Korea, on 30 August 1951. On that date, Company A was attacking a hostile force occupying well-fortified hill positions. The company had fought its way to within a few feet of its objective when a deadly crossfire from the enemy positions pinned the friendly troops down. In the initial burst of fire from the hostile automatic weapons, the company commander was killed and Lieutenant Dunn immediately assumed command and attempted to press the attack. The devastating volume of enemy small-arms and automatic-weapons fire, however, made it necessary for Lieutenant Dunn to place the company in defensive positions. Disregarding his personal safety, he moved among his men, shouting words of encouragement and pointing out advantageous positions from which they could return the hostile fire. While moving across the exposed terrain in an effort to instill courage in his men, Lieutenant Dunn was killed by a burst of fire from an enemy machine-gun, but his example of fearlessness so inspired his men that they successfully held their positions against overwhelming odds, until the order to withdraw was given. The extraordinary heroism displayed by First Lieutenant Dunn on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
