This genuinely revisionist account of the Battle of France in 1940 proves a deeply shocking fact - we are essentially still in thrall to the view of Blitzkrieg tactics that Adolf Hitler and Joseph Goebbels wanted us to have, even over three-quarters of a century later. Lloyd Clark's brilliant analysis proves that Fall Gelb (the Germans' Plan Yellow) wasn't all about unstoppable, superior panzers and Stukas, but was in fact an audacious, highly risky infantry-based plan that could have gone badly wrong given a different Allied mindset.
