Question about movement and Combat.

Let's say I have armies in Provinces A & B and my opponent has armies in province C And D. Province B does NOT border province D! I attack Province C from both A&B. My opponent attacks province A from C&D. How does it resolve? To my 2 armies meet his 1 army in province C? Or do the armies in the provinces being attacked stop and defend so it's 1 army vs 1 army? Think of a province setup like a "Z" and how it's resolved.


Finally, let's say there's only 2 provinces(this is simpler) and We attack each other at the same time...Is there a defender or do you meet on neutral ground?

thanks bundles.
