Campaign Waterloo question

[LarkinVB]

1. Did someone play the 388 turn large campaign?
Since the prussians can't bring their supply waggons with them in time if the french do the western approach, will the prussians be able to get supply from british waggons if they are low on ammo?
If not it seems the western approach is a default win for the french as the prussians can't fight properly without ammo.

2. Will the base unit of a light batallion which did split into skirmish companies also count as skirmishers in combat? It is not marked as such.
