Sailing 1 August 1944 for Oran, "Doyle" departed from that port ten days later for the invasion of southern France, escorting a convoy to the assault area and patrolling to cover the landings. She continued to support the invasion by escorting convoys from Naples and patrolling off Marseilles until 21 September when she sailed for the United States, arriving at New York 3 October for overhaul.
