My first impression of the scenario is that the well positioned French forces liberally sprinkled with "skirmishers" and cavalry would have a cake walk.
The Russians can be a tough nut to crack. To maximize Russian victory points they have to advance and concentrate their right flank force;otherwise, they are subject to defeat in detail from Friant. Also, a French breakthrough here would allow them to get easy banners from exiting units. In the middle, the Russians can use their artillery combined with their infantry to hold the French at bay. The other key is for them to get their reserve cavalry to support their left flank. A well-timed, well-supported assault here can let them run the French right.
That said, this strategy is easier said then done against a careful French opponent who keeps his wings and advances well supported.
With regards to Michalxo's concerns regarding this scenario, one change is probably a necessity: Change the "town" condition to read, either player may score 1 temporary majority banner for holding these 3 town hexes.
