Well remembered SA. My memory was hazier, but I did recall thinking that the French had the advantage of knowing the battle had to be won quickly as Blucher would arrive around 4 pm, which Napoleon himself did not know.

Its the point made above I suppose, that you either have to have rules forcing you to make more or less the mistakes that were made historically, or you have to accept you aren't really "refighting" the battle because both sides apply the wisdom of hindsight.
