Here are the World at War Vichy France rules:
5.5 Fall of France, and Vichy France: When an axis player conquers France, France must give the conquering player 3 IPC’s from the French money and lower France’s IPC level by 6.
The French player then rolls a die for each French Fleet in the Atlantic and Mediterranean.
On a roll of 1: The French Fleet joins the Germany.
On a roll of 2-4 : The fleet is scuttled and removed from play.
On a roll of 5: The fleet becomes Vichy French and immediately moved to the nearest Vichy land/sea area. In the rare instance where there are no Vichy areas, then the fleet is not moved and immediately reverts to Free French. If two Vichy areas are of equal distance, the axis player chooses which area the fleet is moved to. If the fleet is moved to French Indo China and French Indo China joins Japan through political influence, the fleet remains Vichy, and would join the allies if the allies ever succeed in taking French Indo China. If Japan attacks French Indo China instead of gaining it through political means, the fleet would join Britain.
On a roll of 6: The fleet is Free French, but under British control and French pieces are replaced with British pieces. The British players then uses the same steps to resolve the fate of the French Fleet in the Mediterranean.
The British player then rolls a die for each French area that is not already controlled by the axis. On a roll of 1-3 the area becomes Vichy, and on a roll of 4-6 the area remains Free French.
THE FRENCH AREAS ARE:
Morocco, Algeria, French West Africa, French Equatorial Africa, Madagascar, Syria, French Indo-China, the Mauritius Islands, the Fiji Islands and the Society Islands.
After the areas are rolled off, the German player then places two control markers (to show the area is Vichy and not Germany’s) on all Vichy areas except for Society Islands and Fiji Islands, which would fall under Japanese control if Vichy (use Japanese markers). Once all rolls are made, adjust France and the axis positions on the income chart for areas that became Vichy.
5.6 Treatment of Vichy Territories: Although the Axis players get IPCs each turn from the Vichy areas, the axis may never build units on Vichy areas, nor may the Axis move units through or over Vichy areas.
If a Vichy area or fleet is attacked by an axis player all Vichy areas and fleets become Free French. This is for the axis only; if the allies attack a Vichy area there is no effect on other Vichy areas or fleets whether the attack failed or not. If the allied attack failed, the area would remain Vichy.
Vichy areas captured by British, Free French or the U.S. resort to Free French.
Vichy troops defend themselves from any attackers, whether they are the axis or the allies. Vichy forces may not move. Vichy naval units are considered neutral and never block a sea zone.
If an the allies capture all Vichy areas adjacent to a Vichy fleet, then the fleet becomes Free French.
