The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to First Lieutenant (Infantry) William H. Guinn (ASN: 0-2017052), United States Army, for gallantry in action as a member of Headquarters, 2d Battalion, 21st Infantry Regiment, 24th Infantry Division, in action near Angang-ni, Korea, on 5 – 6 September 1950. During a tactical withdrawal his battalion was attacked by a large enemy force which had established a strong roadblock along the route of withdrawal. Utterly disregarding his own safety he left his position of relative safety and moved to the head of the column in order to ascertain the enemy’s strength and disposition. After securing this vital information he began the perilous return to the battalion command group. As he moved along the column the enemy increased the intensity of his fire. Determined to eliminate this source of the enemy’s strength Lieutenant Guinn armed himself with hand grenades and fearlessly moved to a position from which he could observe the enemy group. Hurling grenade after grenade he silenced three machine guns and killed or wounded their crews. He then continued his return to the command group furnishing information which ultimately led to the enemy’s complete dispersion with heavy casualties. Lieutenant Guinn’s gallant actions and complete devotion to duty reflect the greatest credit on himself and the United States Infantry.
