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 Sergeant William J. Peifer (ASN: RA-13280136), United States Army, for conspicuous gallantry and intrepidity in action as a member of Company M, 3d Battalion, 21st Infantry Regiment, 24th Infantry Division. Sergeant Peifer distinguished himself by courageous action near Kanyong, Korea, on 25 April 1951. He was leading his squad in an assault on two enemy machine gun positions in the fog-bound area surrounding the town. Alone, he knocked out one gun emplacement and then started toward the other, but heavy enemy fire held him down and finally forced his squad to withdraw. He voluntarily covered the withdrawal and, while engaged in a fierce fire duel with enemy troops, was mortally wounded by an enemy round when trying to make his own withdrawal. Sergeant Peifer’s courageous actions reflect the highest credit on himself and the United States Infantry.
