Country side area north of Rome
I'm a feder-allergic and I blame the Klingon for not having smashed the Federation in time to save us from Star Trek serials.
Just a fast note. What you are asking about is covered in two paragraphs quoted here after of the War and Peace section of the rules book.
Repatriation of Forces: All troop and Ship forces (except monitors and planetary defenses) are repatriated. They are immediately returned to the owning player's homeworld. Their current position has no immediate importance in this procedure. Any worlds or outposts which are neutralized at this point reamin neutralized.Second quote:
Redistribution of Forces: All forces except monitors may be redistributed by both sides prior the start of hostilities. They may be placed in any system containing a friendly world or outpost marker. The winner of the war set up first.
All forces automatically begin the new game in an undisrupted state.
Then, on Dragon #20 appeared a page of Imperium Rules Clarifications. In them, on maintenance, were said the following things:
Maintenance: Almost as hard on anyone’s forces as combat is maintenance and the requirements thereof. This aspect of the game was inserted to catch the feel of the economic drain of war, and it does so nicely. Maintenance must be performed, or ships just dry up and become almost useless. More specifically, ships sent off in support of a civil war must be fully operational when they leave (though maintenance is assumed to be ongoing without charge while they are away). Similarly, ships which the Emperor grants or loans must be maintained while they are present, and when they must leave, they must be fully operational.
I think this will help you.
