The 391st Bombardment Group was a medium bomber unit that served with the Ninth Air Force in Europe, supporting the D-Day invasion and the campaign that followed.

The group was activated in January 1943 and trained with the Martin B-26 Marauder. It moved to England in January-February 1944 and joined the Ninth Air Force, the American contribution to the tactical air forces that were to support the D-Day landings. The group entered combat on 15 February 1944, and was used to attack transport links, V-weapon sites and airfields across France and the Low Countries.

On D-Day and D+1 the group attacked German coastal defences on the invasion beaches. From then until September the group attacked transport and communications links, fuel dumps and German troop concentrations. It supported the breakout at St Lo in July 1944.

On 6 July 1944 the 391st attacked the long viaduct at Maintenon, breaking the rail line to Chartres. The viaduct was soon repaired, but a second attack on 25 July broke it again.

In September 1944 the group moved to the continent, and was able to extend its area of operations to include Germany. Troops, transport links and ammo dumps remained key targets. The group also took part in the battle of the Bulge, attacking German transport links between 23-26 December.

On 23 December the 391st flew two missions. In the morning it attacked the Ahrweiler bridge, despite having failed to meet up with its fighter-bomber escort. Sixteen aircraft were lost in the morning attack, but the group was still able to carry out its afternoon mission. It was awarded the Presidential Unit Citation for the two raids.

During 1945 the group concentrated its efforts against the German transport network and communications links. It converted to the A-26 Invader in April 1945 but flew its last mission on 3 May after a short period with the new aircraft.

The group was redesignated as the 391st Bombardment Group (Light) in July 1945, but returned to the US in October and was inactivated on 25 October 1945.
