In the days and weeks following the D-Day landings in Normandy, France, on 6 June 1944, Allied bomber forces ranged deep into occupied France, attacking lines of communication and supply. Railway junctions and marshalling yards were heavily bombed to prevent German reinforcements being sent to stem the Allied advance.
One of the key railway hubs targeted was at Amiens. The junction at Longueau, to the south-east of Amiens, escaped attack until the night of 12/13 June 1944 when 200 bombers were sent to destroy it. This sortie records the effect of this attack.
