The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Sergeant Jack R. Grieve (ASN: RA-12343251), United States Army, for gallantry in action as a member of Company A, 1st Battalion, 15th Infantry Regiment, 3d Infantry Division, in action against an armed enemy in Korea. In the cold, early morning hours of 29 September 1951, near Ukkonggi, Korea, during A Company’s attack on Hill 487, elements of the First Platoon were pinned down by intense enemy fire. Sergeant Grieve, ordering his squad to their assistance, fearlessly led the unit forward and, in the events which followed, neutralized three enemy bunkers to free the pinned down elements and gain the crest of the hill. Completely exposing himself to the hostile fire sweeping the area, Sergeant Grieve, observing an enemy 120 millimeter mortar position, voluntarily and single-handedly assaulted the emplacement and killed the five soldiers manning the weapon. Having accomplished this, he was preparing to lead an assault against another gun position when felled by enemy small arms fire. The gallant leadership and courageous aggressiveness displayed by Sergeant Grieve reflect great credit upon himself and the military service.
