The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Staff Sergeant Arnold R. Lambert (ASN: ;7006617), United States Army, for gallantry in action while serving with the Medical Detachment, 16th Infantry Regiment, 1st Infantry Division, in action against the enemy in the vicinity of Mateur, Tunisia, on 28 April 1943. Although subjected to heavy enemy artillery, mortar and machinegun fire, Sergeant Lambert evacuated many casualties from a forward battalion aid station to an area where further medical treatment could be rendered. 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.
