In the weeks following the D-Day landings, RAF Mitchells were sent to operate from advanced airfields in France, to provide support for advancing Allied ground units. The RAF received nearly 900 Mitchells, using them to replace Douglas Bostons, Lockheed Venturas and Vickers Wellington bombers. The Mitchell entered active RAF service on 22 January 1943. At first, it was used to bomb targets in occupied Europe. After the Normandy invasion, the RAF and France used Mitchells in support of the Allies in Europe. Several squadrons moved to forward airbases on the continent. The USAAF did not use the B-25 in combat in the ETO.
