Twice in PBEM games, playing the 1812 Campaign, the whole French army has just vanished after a big battle. Loads of casualties, for sure, but shouldn't vestiges of the various corps and divisions remain?
In the latest incident, I had Napoleon with Grand Army HQ, and 3 full-strength corps, attacking Smolensk. There was a heavy battle. End result, every single unit in the French forces is gone, and all the leaders are sitting in a nearby town.
For sure I'm a lousy general, but this result doesn't seem realistic.
