The squadron was temporarily stationed at RAF Gosfield upon its arrival in England in early April 1944. On the 15th of the month, its parent group displaced the 363d Fighter Group at RAF Rivenhall and flew its first combat mission five days later.[3][5] In preparation for Operation Overlord, the invasion of Normandy, the squadron participated in Operation Crossbow, attacking V-1 flying bomb launch pads. It also struck bridges, coastal defenses, marshalling yards and airfields in northern France. On D-Day the squadron attacked strong points and bombed fuel dumps and other objectives to support ground forces throughout the Normandy Campaign.[3]
In July 1944, the squadron participated in Operation Cobra, attacking German forces near Saint Lo, France, during the Allied breakout there. In August, the squadron moved from England to Gorges Airfield, an Advanced Landing Ground in France. From there it attacked naval targets at Saint Malo and Brest. Once on the Continent, the squadron made frequent moves forward as the Allied forces advanced during the Northern France Campaign. By September the squadron began flying missions into Germany, attacking depots and defended areas.[3]
During the Battle of the Bulge, the squadron struck enemy lines of communications. On 23 December 1944 the unit severed a railway bridge at Ediger-Eller, Germany, despite heavy flak and fighter opposition from the Luftwaffe. For this action it was awarded a Distinguished Unit Citation. The squadron continued to fly missions to support the Allied drive into Germany until 20 April 1945, exactly one year after its first combat mission, having completed 239 combat missions.[3][6]
After V-E Day the squadron returned to its former base at Peronne Airfield, France, and remained there until December, when it returned to the United States. Upon arrival at Camp Shanks, New York in early January 1946, the squadron was inactivated.[3]

^Maurer says 1943–1946, but the squadron was either at sea or at the port of embarkation for the five days it was active in January 1946, and was not equipped with aircraft.
