branch city

What will happen to soldiers out hunting and oasis connected to a branch city, if the branch city is taken by another player? Will the army and oasis go to the main city or are they also lost?

If troops are hunting from a sub city, and the sub city is taken over, the soldiers don't return, they just disappear. Also with Oasis', If they're connected to a sub when it's taken over, they'll be resigned.
