The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Sergeant William B. Terwilliger (ASN: RA-17277688), United States Army, for gallantry in action as a member of Headquarters Company, 1st Battalion, 9th Infantry Regiment, 2d Infantry Division, in action against enemy aggressor forces near Senchon, Korea, on 20 May 1951 in the vicinity of Senchon, Korea. On that day the 1st Battalion of the 9th Infantry Regiment counter-attacked an enemy force far superior in number to its own, During the fiercest portion of the attack Sergeant Terwilliger sighted an abandoned machine gun position. Disregarding the intense enemy fire, he dashed across a mine field and lunged into the emplacement, placing the weapon in correct position. He then manned the machine gun throughout the attack, killing forty of the enemy. Sergeant Terwilliger’s undaunted courage and devotion to duty reflects great credit upon himself and upholds the highest traditions of the Military Service of the United States.
