"But of course we must evacuate...If only to get revenge on Vichy traitors when they least expect it."
The trick is to evacuate with an HQ and five units ( the command limit, preferably the air unit, an armor unit, two corps 'Algerian and Mid-East and an army.) A pretty effective force under the command of a general, especially after building up experience in N.Africa. If you use the foriegn legions as two of the units your over-all defence isn't comprised too much. After all, your going to fall very quickly to any experienced axis player, might as well have an effective surviving force. Viva La France!
