Thank you for the quick answer. :)
You might want to consider adding this issue to the Revised FAQ/Errata (just using the wording on the AA50 manual would do it). This issue turns up every once in a while on forums.
So I have a question about what moves are allowed in the following situation:
England has a fleet in the Baltic Sea region (forgive me I don’t remember the SZ no.), which includes transports. Germany purchases submarines on its turn, making the SZ hostile.
Can england use its transports to move out of the hostile zone, pick up troops, and then move back in to the hostile zone (and then conduct an amphibious assault as normal if the subs are defeated) or must the transports, if they retreat, end up in a friendly sea zone? Further (and related) are there ANY restrictions on movement caused by starting in a hostile zone rather than a friendly?
Thanks.

Yes, this is legal, as long as the sea zone in which the transports are loading units is friendly.

The movement must be done in the Combat Movement phase. It must follow all of the rules for Combat Movement, except that it need not end in combat.
