Murphy's first Purple Heart was for a heel wound received in a mortar shell blast on 15 September 1944 in northeastern France. His first Silver Star came after he killed four and wounded three at a German machine gun position on 2 October at L'Omet quarry in the Cleurie river valley. Three days later, Murphy crawled alone towards the Germans at L'Omet, carrying an SCR-536 radio and directing his men for an hour while the Germans fired directly at him. When his men finally took the hill, 15 Germans had been killed and 35 wounded. Murphy's actions earned him a Bronze Oak Leaf Cluster for his Silver Star. He was awarded a battlefield commission to second lieutenant on 14 October, which elevated him to platoon leader. While en route to Brouvelieures on 26 October, the 3rd Platoon of Company B was attacked by a German sniper group. Murphy captured two before being shot in the hip by a sniper; he returned fire and shot the sniper between the eyes. At the 3rd General Hospital at Aix-en-Provence, the removal of gangrene from the wound caused partial loss of his hip muscle and kept him out of combat until January. Murphy received his first Bronze Oak Leaf Cluster for his Purple Heart for this injury.
