Screening duty in the English Channel preceded "Carmick"s departure for the Mediterranean on 18 July 1944. Convoy duty in connection with the buildup for the invasion of southern France continued until 15 August, day of the preliminary attacks on the coast between Toulon and Cannes. Once more "Carmick" was in the van of the invasion fleet, with duties similar to those she had at Normandy. Her constant vigilance was rewarded 18 August, when she destroyed an enemy E-boat. She supported the consolidation of the beachhead by convoy escort duty in the western Mediterranean until 23 September, when she cleared for New York City.
