High Quality Content by WIKIPEDIA articles! The Battle of Sedan or Second Battle of Sedan was a decisive battle fought during the Battle of France during the Second World War. The battle was part of the German Wehrmacht's battle plan to encircle the Allied Armies in Belgium and north-eastern France. The German Army Group A crossed the Meuse river with the intention of capturing Sedan and pushing northwards towards the channel coast, in order to entrap the Allied Forces that were advancing east into Belgium, as part of the Allied Dyle Plan strategy. The initial assault was spearheaded by the Luftwaffe. Owing to the bombing and low morale, the French defenders broke down psychologically and were unable to mount a coherent defence. The Germans captured the Meuse bridges at Sedan allowing them to pour reinforcements and armour across the river on 14 May. The Allied Air Forces, the Royal Air Force (RAF) and Armée de l'Air (French Air Force) tried to destroy the bridges only to be prevented by German aerial resistance leading to very high losses and the breaking of the Allied bomber strength in the campaign.
