If you are going to allow the combat map to infinitely expand, then it is necessary to modify all the combat code to incorporate the following:

First, defer combat until forces from all surrounding hexes have committed to the battle.

Second, forces entering from different hexes should be placed according to the hexes they entered from.

So, you either use a limited combat map. Or, you alter the combat code to allow 'englobing' attacks. Pick whichever is easiest to implement. :-)
