 At first, it was engaged primarily in escort activities to cover Boeing B-17 Flying Fortress and Consolidated B-24 Liberator bombers that attacked airfields in France, and later expanded their area of operations to provide escort for bombers that struck rail centers in Germany and oil targets in Poland.The group supported the invasion of Normandy during June 1944 by patrolling the English Channel, escorting bombardment formations to the French coast, and dive-bombing and strafing bridges, locomotives, and rail lines near the battle area.During the period July 1944 - February 1945, the group was engaged chiefly in escorting bombers to oil refineries, marshalling yards, and other targets in such cities as Ludwigshafen, Stuttgart, Frankfurt, Berlin, Merseburg, and Brux.
