Australian airmen were involved in Allied efforts to delay German reinforcements from reaching Normandy throughout June. On the night of 6/7 June, 20 Mosquitos from No. 464 Squadron were dispatched to attack German road convoys and trains in northern France. The four Australian heavy bomber squadrons also participated in raids on French towns on this night. While No. 463, No. 466 and No. 467 Squadrons mainly targeted railway facilities, No. 460 Squadron formed part of an attack on Vire, which sought to destroy the town to prevent the Germans from using the roads through it. Following these initial raids, Bomber Command continued to target railway infrastructure in France in an attempt to disrupt the movement of German reinforcements to Normandy. The command operated intensively during the week after the invasion, and some Australian aircrew flew raids on consecutive nights during this period. Overall, Bomber Command made 16 raids against railway facilities in France between 13 and 30 June, of which six included at least one of the RAAF squadrons. The RAAF heavy bomber squadrons and Australians in RAF units also took part in several attacks on German supply dumps and airfields during this period. Bomber Command made fewer raids on these targets than had been planned prior to the invasion, however, as its units were frequently assigned to strike facilities associated with the V-1 flying bombs the Germans were launching against the UK. No. 464 Squadron also operated against German vehicles travelling at night and bombed railway yards, and flew 75 sorties between the nights of 7/8 and 12/13 June. Overall, the squadron conducted attacks on 19 nights during June, during which five of its aircraft were destroyed. The Australians in 2TAF's other light and medium bomber units also attacked the German lines of communication in France and occasionally provided direct support for the Allied ground forces throughout this period.
