Three days later, the destroyer departed Plymouth in the screen of a 50-ship convoy bound for North Africa and arrived in Bizerte, Tunisia, on 28 July. She operated in the western Mediterranean mostly between Oran, Algeria, and Naples, Italy before arriving off Saint-Tropez on 15 August, D-Day for the invasion of southern France. "Baldwin" served there as an element of the Antisubmarine and Convoy Control Group, Task Group 80.6 (TG 80.6) which screened follow up convoys between Oran and southern France. On 23 September, she concluded her part in that operation and departed Oran in company with her division mates bound for the United States.
