"Emmons" returned to Mers-el-Kebir 10 July 1944 with a transport convoy she had brought across from Portland, then had escort duty in the Mediterranean ports preparing for the assault on southern France. She sailed from Taranto, Italy, for the beachheads, 11 August, and on the 15th began pre-invasion bombardment. She remained off the beaches all day to provide fire support to troops storming ashore. Escort duty took her away to Italian and Corsican ports, but she returned to patrol off the French Riviera until October.
