Sub question

In all current forms of the game since AA Anniversary edition, subs (and transports) can not and do not ever block movement.  So if in your example you can attack a stack of subs with a stack of destroyers and other units are free to proceed through to another seazone, even though there will be combat in that seazone (destroyer on sub).

@Fighter:

Whatever fleet you build as UK, you are free to place in the seazones around UK. Then on the german players turn, he has 2 options: stay and fight against whatever fleet you might have built, or to run away.

This is correct. You may put new naval units in a zone that still contains enemy units.

Yep. Whatever that country has in their bank is now yours.

A capitol fall is very hard to come back from because of that. The toppled country misses a turn of buying units (no $$$) while at the same time giving the other side the chance to purchase with their normal collection plus the plundered treasure.

You probably want to browse around some of the games being played on the site (in the Games topic area).

Your question ahs no short answer, but I think you will see once you start to look around some strategy options for the Axis that are quite effective (this coming from a player with a better win record as the Axis than I have as the Allies)

No.  All combat is simultaneous, therefore the combat in the front territory is still going on and you cannot blitz through.

Thanks alot for the help  :-)

ah

Thanks for the help.
