History World War II Formed at Westover Field, Massachusetts in August 1943, the 371st Fighter Group trained in the mid-Atlantic area, and moved to the European theater during February and March 1944, serving in combat with 9th Air Force from April 1944 to May 1945. During this time, the 371st Fighter Group began operations, using P-47 fighter aircraft over France. This involved dive-bombing, and escort missions prior to the invasion of Europe. Additionally, the 371st attacked railroads, trains, vehicles, gun emplacements, and buildings in France during the invasion on June 6, 1944. The Fighter Group also patrolled beachhead areas and continued its assaults against the enemy during the remainder of the Normandy campaign. This included participation in the aerial barrage that prepared the way for the Allied breakthrough at St Lo on July 25, and supported the subsequent drive across northern France. Operated in the area of northeastern France and southwestern Germany during the fall and winter of 1944–1945, attacking such targets as storage dumps, trains, rail lines, marshalling yards, buildings, factories, bridges, roads, vehicles, and strong points. Conducted operations that supported Allied ground action in the Battle of the Bulge, December 1944–January 1945. Launched a series of attacks against vehicles, factories, buildings, railroad cars, tanks, and gun emplacements during the period 15–21 March 1945, being awarded a Distinguished Unit Citation for this six-day action that contributed to the defeat of the enemy in southern Germany. Continued operations until May 1945. Returned to the US, October and November 1945, and inactivated.
