The Storm of War - Andrew Roberts [35]
With the French armour divided between three armoured cavalry divisions, three heavy armoured divisions (initially all held in reserve) and more than forty independent tank battalions supporting infantry units, other than General René Prioux’s Cavalry Corps no French motorized formations acted in concert during the campaign.25 Having failed to break through southwards, the BEF and French First Army fell back towards Dunkirk. Gaston Billotte died in a car crash on 21 May, an accident that led to a ‘feeling of inexorable Fate’ overcoming the French High Command, whose morale, in Beaufre’s view, was never to recover from Corap’s defeat at Sedan.26 The next day, 22 May, the RAF lost Merville, its last airfield in France, so that henceforth every British plane that flew over the Allied armies had to come from across the Channel, severely limiting the amount of time they could spend engaging the Luftwaffe.
A full week before the evacuation from Dunkirk began on 26 May, no fewer than 27,936 men who were not central to the functioning of the BEF were evacuated, in an operation organized by Lieutenant-Colonel Lord Bridgeman of the Rifle Brigade on the Continent and Vice-Admiral Bertram Ramsay, the Flag Officer in Dover.27 Cartographers, bakers, railwaymen and other ‘useless mouths to feed’, as they were accurately if rather uncharitably described by Bridgeman, were shipped back, a clear indication that things were not expected to go well. Nor did they: on 24 May Army Group A and Army Group B joined forces to push the Allies into a rapidly diminishing corner of France and Belgium, by then stretching only from Gravelines to Bruges and inland as far as Douai.
Then something astonishing happened. With Kleist’s Panzers only 18 miles from Dunkirk, indeed closer to it than the bulk of the Allied forces in the Belgian pocket, they were given an order to halt by Hitler that countermanded the Wehrmacht Commander-in-Chief Brauchitsch’s order to take the town. This specified that the line of Lens–Béthune–Saint-Omer–Gravelines ‘will not be passed’.28 For reasons that are still debated by historians, Hitler’s so-called Halt Order of 11.42 hours supported Rundstedt’s request to halt Kleist’s Panzers at the front line on 24 May and not move into the pocket.29 To the amazement and immense frustration of commanders like Kleist and Guderian, the coup de grâce that might have scooped up the entire northern Allied force was not put into operation, giving the Allies a vital forty-eight-hour breathing space which they used to strengthen the perimeter and begin the exodus from the beaches of Dunkirk. General Wilhelm von Thoma, chief of the tank section of OKH, was right up forward with the leading tanks near Bergues, from where he could look down into Dunkirk itself. He sent wireless messages to OKH insisting that the tanks push on, but was rebuffed. ‘You can never talk to a fool,’ he said bitterly of Hitler (after the Führer was safely dead). ‘Hitler spoilt the chance of victory.’30 When Churchill later spoke of a ‘miracle of deliverance’, it was one performed by the grace of Rundstedt and Hitler, as well as by Gort and Ramsay. It was the first example of very many cardinal errors that were to cost Germany the Second World War.
‘I must say that the English managed to escape that trap in Dunkirk which I had so carefully
