The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Second Lieutenant (Quartermaster Corps) Earl L. Duncan (ASN: 0-1170721), United States Army, for gallantry in action while serving with 1st Quartermaster Company, 1st Infantry Division, in action against the enemy in the vicinity of Aidi Nsir, Tunisia, on 29 April 1943. Disregarding his own safety, Lieutenant Duncan resolutely advanced under intense hostile mortar and machine-gun fire and evacuated a wounded man to an aid station. He then returned to his forward observation post and directed accurate artillery fire on enemy strongholds. His gallantry and initiative were instrumental in enabling the infantry to seize its objective and to consolidate its positions. His gallant actions and dedicated devotion to duty, 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.
