The Belgian intelligence service passed to the western Allies a copy of the original Case Yellow plan [a replay of 1914], after a Luftwaffe officer flying to one of the German Army Groups [probably ‘B’], got lost in the fog and crashed in Belgium. By the early Spring of 1940 informal talks with the Belgians had proceeded to the point where the French and Brits changed their operational plan to include the ‘Dyle maneuver’, moving the French Seventh Army to the extreme left flank to not only link up with the Dutch, but also to cover a corner of Belgium and link up with the Belgian Army. That Army came from being in reserve - behind Sedan, where my beloved Panzer Leaders [Kleist, Hoth Guderian and Rommel] came storming through. The Dutch were much closer to the Allies and somewhat more open about it [I believe a Dutch intelligence officer was captured with Stevens and Best at Venlo].

I hadn’t read this post before i put mine up (viz “cooperation”). You may be right on that point.

Sorry, but you are reading history in reverse. It was only after the Luftwaffe officer got lost and the Belgians saw that the Nazis were going to invade, that they began to have anything to do with the allies. And they still refused to have allied forces at their border with Germany.

What is your excuse for Denmark and Norway?
