Question re: large battles

[Crimguy]

Say you have 2 Corps descending on the same region from different locations, e.g. one corps coming from the east and one from the west, with the destination being occupied by an enemy unit. How does the game count their confrontation with an enemy in the target region? Does each corps have their own battle summary, or does it all get mashed together if they arrive within a certain time of each other?

If they are represented as separate battles, how much time must expire before the computer determines them to be, in fact, separate and distinct from one another?

All forces in a zone are rolled into a single combat (though some may not effect the outcome of the battle). More then one such combat can occur in a single turn, so the situation of which units are present or not may well have changed from one combat to the next in a region.

for a given day, you can have at most one combat occuring in a region. Now corps A can be engaged while corps B is not, this is a possibility...
