The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting a Second Bronze Oak Leaf Cluster in lieu of a Third Award of the Silver Star to Colonel (Infantry) William Joseph McCaffrey (ASN: 0-22065), United States Army, for gallantry in action while serving while serving as Commanding Officer of the 31st Infantry Regiment, 7th Infantry Division, in action against the enemy in Korea, in June 1951. During the fighting near Huachon, Colonel McCaffrey, after ordering his 2d Battalion to secure an enemy-held hill, left his observation post and moved under heavy enemy artillery fire to reach the battalion commander where he gave advice on the attack. Colonel McCaffrey advanced with fighting elements, personally directing artillery fire, until the hill was secured, and then established his observation post on the new hill in view of the enemy. He was credited with being materially responsible for the success of the mission. The gallant actions and dedicated devotion to duty demonstrated by Colonel McCaffrey, without regard for his own life, were in keeping with the highest traditions of military service and reflect great credit upon himself and the United States Army.
