April 7, 1940
French Front:
German forces launch Case Yellow and successfully cut supply to Paris from Dieppe and Orleans in addition to making contact with Paris from two directions. The German forces that have reached Paris are, however, badly mauled and ripe for counter-attack.
French colonial forces are recalled to the mainland and 4-5 divisions reach France proper with more to come, assuming France is still in the fight at that time.
The French have lost supply to the main bulk of its forces, so re-establishing a supply line is the top prioroity. Cut off troops will also counter-attack to regain communications. Finally, attempts will be made to push the Germans away from Paris.
