As the Italian Campaign pushed further north into Italy during 1944, the squadron moved to operate from forward captured air bases, flying bomber escort missions initially with Republic P-47D Thunderbolts, then being upgraded to the long-range North American P-51D Mustang fighter. In combat, the unit engaged enemy forces in the Rome-Arno area, then during the D-Day landings in France, took part in the Normandy and Northern France campaigns. It returned to the MTO in August 1944, flying combat missions supporting the Invasion of southern France and attacking enemy targets in Northern Italy, Po Valley, the German Rhineland and the Western Allied invasion of Germany during March and April 1945.
