On the 19th May 1940 General Ironside requested that Lord Gort attack south with the BEF. Would the British be capable of putting the bulk if not all their forces into the thrust whilst De Gaulle attempt the same from Ameins? The Belgian right flank would obviously collapse a few days sooner, but the British could briefly isolate Guderian before being push south by the rest of the Heer resulting in no Operation Dynamo, but greater Operation Cycle and Operation Ariel. Thoughts?
