PRUSSIA & AUSTRIA AS VASSALS: If France captures Berlin or Vienna then the Prussian
or Austrian player must act as a vassal of France. France cannot capture any more
territory from that nation (exception: Poland) but it may send French troops through their territory.
It is up to the Vassal nation how much they co-operate with the French. They may
just allow access, they may join forces with the French.
Vassal status is terminated if the capital is liberated by a foreign power.
If both Prussia and Austria are vassals, the other nation is automatically "freed" too, if one nation is liberated by a foreign power.
