Clearly if the Allies had put the full weight of their forces into the battle there would have been no or little contest as you'd be looking at a battle of 50,000 vs 30,000
I agree . that's why I would keep St Priest as reserve and after the entry of the french 9th division have the mandatory CMT for a russian infantry corps to go forward ( towards the ennemy ) . it might represent the fear of the ennemy and the FOG of war + add some uncertainty in the scen
While looking at re-doing the lists I noticed my mistake in citing the strength of Fournier's division. In the post above the <600 troopers is for one brigade only. The total division is >1,100 troopers. So a combined Fournier/Defrance division should have Fournier as an exceptional, charismatic divisional commander and Defrance as a brigade commander - the division would have 2 light cavalry units (Fournier's division) and one dragoon unit (Defrance's).
Sorry about that. I've edited the post to correct that error.
