The entire French "empire" goes over to the Allies? That's a huge win for the Allies.[6] An earlier attempt at Case Anton by the Axis brings about the same response as OTL.
But apparently not, since the mutineers were arrested by Vichy afterwards. But then how does Darlan meet with De Gaulle in North Africa?
Still, the Allies may get West Africa, Syria, Madagascar, the West Indies. If Richelieu is at Dakar, that's big.
However... I don't see the crews scuttling their ships. For one thing, that wouldn't save them from being conscripted for labor. Moving the ships to a neutral port (Lisbon? Surely not Spain.) would be much safer. Or, as ISTR, the British also suggested steaming to the West Indies.
