"On 1 Dec 1944 Technician Fourth Class Guillermo C. Alvarez of the 415th Inf Medical Detachment left his covered position under withering machine gun fire to go forward and give aid to and evacuated a badly wounded man 100 yards away. The leg wound of the man made the process of the evacuation very slow, but Technician Alvarez continued until he was brought back to safety."
