The cargo ship set sail on 27 February to rejoin the war effort in the Mediterranean. After several rehearsals at Salerno for the amphibious landings in southern France, "Arcturus" joined TF 85, the "Delta" Force in this operation, and stood off the designated beaches at La Nartelle on 15 August, awaiting H-hour, 0800. The assault progressed like a textbook drill due to excellent gunfire support, air cover, and experienced boat crews. The landing was unopposed. There were no casualties and no loss of landing craft
