The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to Private First Class John N. Giellis (ASN: RA-17281374), United States Army, for gallantry in action as a member of Company K, 38th Infantry Regiment, 2d Infantry Division, in action against the enemy on 30 July 1951 in the vicinity of Taeusan, Korea. On that date during an attack on strategic enemy positions, Company K was pinned down by intense enemy small arms, automatic weapons, and grenade fire. Realizing the importance of the mission, Private Giellis, with complete disregard for his personal safety, left his position of cover and advanced toward the enemy position throwing hand grenades and firing his rifle. He succeeded in destroying the hostile emplacements that were delaying the advance of his unit and inflicted numerous casualties upon the enemy. As a result of his heroic action, friendly units were able to continue the advance with a minimum of casualties and successfully complete their mission. The gallantry in action displayed by Private Giellis on this occasion reflects great credit upon himself and the military service.
