After repairs in the Philadelphia Navy Yard, "Oberon" returned to North Africa in April via Cardiff, Wales. As part of Assault Group II preparing for the invasion of Southern France she practiced landings until 13 August along both the Algerian and Italian coasts. D-Day, the 15th, went smoothly as she landed 151 soldiers and sailors plus valuable support equipment at St. Tropez, France. After five additional logistic missions from Oran and Naples, the attack transport joined a convoy en route to the United States late in October.
