The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Silver Star (Posthumously) to Private First Class Donald R. Roberts (ASN: ER-57501115), United States Army, for gallantry in action as a member of Company E, 38th Infantry Regiment, 2d Infantry Division, in action against an armed enemy on 13 January 1951 in the vicinity of Oneamsong, Korea. Company E had the mission to defend high ground when its forward platoon came under a fierce attack by numerically superior enemy forces. Private Roberts immediately volunteered to leave his relatively safe position in the rear to join the front line defense. When he attempted to open fire, his weapon refused to function. He then began to hurl hand grenades at a group of rushing enemy, causing heavy casualties among them and causing them to retreat. When the attack had been repelled, eight enemy killed by hand grenades were found to the front of his position. The gallantry displayed by Private Roberts reflects the highest great upon himself is in keeping with the fine traditions of the military service.
