The Germans perform photo reconnaissance of the known French positions (see below):
The French Weygand Plan is to form a continuous series of defensive hedgehogs. Critical points are independently held by mixed arms forces under a localised command structure. Interlocking mutual support between the hedgehogs is impossible after the losses incurred in the first part of the French Campaign. Reserve mobile French forces have been held back to form powerful counter attacking forces to destroy any penetrating German attacks.
Well that is the plan!
