Shock and friction as explanations for disaster at the Battle of Amiens, 8 August 1918

The assault at Amiens was ‘the black day of the German Army’. British accounts treat the Germans as passive, of no more importance than the terrain, and victory as inevitable. Using German sources, and drawing on statistical ‘historical analysis’ of behaviour in battle, the article argues the frontline defenders panicked when thick fog left them defenceless against the British tanks. By contrast, when the fog lifted, the defence recovered. Although senior German commanders on the spot reacted well, Ludendorff fell into a state of shock, such that he convinced the Kaiser the war must be ended.
