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 William W. Lyons (ASN: RA-27503652), 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 this date during an assault to secure dominating terrain features, the unit met heavy enemy resistance, halting its advance. Private Lyons assuming command of his squad after the leader was wounded, crawled to within a few yards from an enemy machine gun emplacement and kept the crew pinned down with rifle fire while his squad advanced. When his weapon failed to function, Private Lyons threw a grenade into the emplacement, completely destroying it and killing its crew. As a result of his courageous actions, his unit was able to continue in the advance and successfully secure its objective. The gallantry and outstanding leadership displayed by Private Lyons on this occasion reflect great credit upon himself and the military service.
