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 Sergeant First Class William Eugene Gallup (ASN: RA-37862735), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with Company D, 1st Battalion, 27th Infantry Regiment, 25th Infantry Division. Sergeant First Class Gallup distinguished himself by extraordinary heroism in action against enemy aggressor forces near Haman, Korea, on 3 September 1950. As section leader of a heavy machine-gun section, Sergeant Gallup discovered one of his machine-guns threatened by an enemy force which had infiltrated through friendly lines. Sergeant Gallup, armed with only a pistol and hand grenades, went forward alone under intense enemy small-arms and automatic weapons fire with complete disregard for his own personal safety and killed an estimated six enemy soldiers, harassing and neutralizing the enemy until mortar fire could be adjusted on the hill. In this action, Sergeant Gallup gallantly sacrificed his life, but not until his ferocious single-handed assault on the enemy had resulted in his company being able to hold a vital position. The extraordinary heroism and noble self-sacrifice displayed by Sergeant First Class Gallup on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
