Arriving on the 22d, she discharged her Seabee passengers and equipment and took on troops and rolling stock to be transported to Italy. She anchored at Naples 2 July and for the next month shuttled troops and equipment along the Italian coast, to Sicily and to Corsica. On 12 August, with Army personnel as passengers and their tanks and other vehicles as her cargo, she departed Naples for the invasion of southern France. By 0600, 15 August, she stood off St. Raphael awaiting her first beaching on enemy held shores under fire. Moving in at 1745, she had completed unloading by 1945.

During October she completed runs to Italy and Tunisia, returning in November to the Corsica‑Marseilles route. She completed her final Mediterranean assignment, Marseilles-Bizerte‑Oran, in mid‑December and on the 28th got underway for Norfolk. Arriving 14 January 1945, she steamed to New York for overhaul, returning to Virginia in March to take on vehicles for Pearl Harbor.
Underway on 1 April, she joined a convoy for the Canal Zone, thence, on 15 May, steamed north to San Francisco where she loaded explosives and ammunition for use in the western Pacific.

Towed to Florida the following week, she was berthed at Green Cove Springs as a unit of the Atlantic Reserve Fleet.
