June 2021    In May 1940, the much-anticipated German attack on France brings the Phoney War to an end. The French have the largest land army in the world, the Maginot Line giving them hundreds of miles of defences and they know the route the Germans will take. But in the space of only a few weeks, the entire strategic course of World War Two is turned on its head. The Germans have gambled on a new invasion plan, ‘Fall Gelb’ (or ‘Case Yellow’) to set them on a risky route through the Ardennes and a dash to the coast.   With so many dramatic events happening in such a short period of time, we will be telling the story of ‘Fall Gelb’ over two ‘It Happened Here’ episodes.   In this first part, Dr Thomas Cheetham takes us through the planning and first phases of the operation, and the German and Allied intelligence activity that surrounded it.    Special thanks go to Sarah Langston and Dr Ben Thompson for voicing our archival documents.   Image: Commander Denniston’s 1940 Diary ©Bletchley Park Trust 2021   #BPark, #Bletchleypark, #WW2, #OralHistory,
