The Arty is represented in a very Abstract way in this game.
The French can - when they have stormed la Haye Saint - attack the Allied ARTY directly via an extra Attack route. So far this has not too much Impact on the game - except of course the 6 VP/ARTY they are worth in the end.
here my proposed VARIANT:
If both British/Allied ARTY have been eliminated,
the French Player may IGNORE the EXPLOSION spaces on the French attack routes.
Gives some (more) motivation to storm La haye sainte and Bypass the conquered Position to reach the Vritish /Allied ARTY - and adds some Chrome.
If All three French ARTY are eliminated (rare Event), the respective Space Action on the Dark Blue French Attack line (Old Guard Attack Line), which causes an Allied Piece to be eliminated - should be ignored.
