Oran on May Day. The ensuing three months saw her operating out of Oran conducting antisubmarine patrols of the approaches to that port. While operating with a hunting group composed of , , and in mid-May, Woolsey experienced her third and last encounter with a German U-boat. A report of torpedo tracks from a newcomer to the Mediterranean, , brought DesDiv 25 to the area between Oran and Cartagena early on 17 May to commence a two-day search and destroy mission. During the night of 18 and 19 May, the four destroyers split themselves into two search groups and began searching a possible submarine track 10 miles to each side of it. About an hour and 40 minutes into the mid-watch, the four warships received word that a plane had spotted the submarine some 10 miles ahead of Niblack and Ludlow. Those two ships charged to the attack; and, by the time Woolsey arrived on the scene with Benson and , the two destroyers had succeeded in forcing the U-boat to surface after delivering 11 depth charge attacks over the space of four hours. Immediately, all five destroyers opened fire on the submarine while a British Wellington bomber dropped depth bombs from a low altitude near U-960. The German submarine suffered a number of hits before submerging again. Niblack responded with more depth charges. That attack evidently rung the death knell for U-960 for she immediately resurfaced, and her crew scrambled off just as she made her final plunge at about 07:15 on 19 May. The destroyers picked up the U-boat's captain and 21 of her crew. Niblack and Ludlow received official credit for sinking the enemy submarine. Following that action, Woolsey continued relatively routine patrols until the end of July when she began preparations for the invasion of southern France. For that operation, Woolsey was assigned to the Bombardment Group attached to Camel Force. In that capacity, she supported the landings on the right flank of the assault area near Saint-Raphaël. During the 15 August invasion her guns destroyed two German tanks. Very soon after the initial invasion Woolsey shifted to supporting the 1st Airborne Task Force's drive along the coast toward Italy. She fired upon enemy lines of communication along the coast particularly roads and supported the liberation of Cannes on 24 August. The destroyer continued her operations along the Franco–Italian coast until late October. At that time,
