Scenario is a straight forward situation simulating the Prussian attacks on afternoon of Zorndorf after failed morning assault, strangely the Russians have no artillery Prussians only a single battery.
There are rules in BP version for several Russians units being Valiant and several units on both sides being small or worn and similar.
I did not replicate much of this other than Prussians losing First Fire ability and having two small (3UI) foot units.
Not a lot of terrain either with only a large swampy area to Russian rear and a light wood (the Stein Busch) and Zorndorf itself.
Large cavalry engagement on Prussian right led by their Cuirassier units (3 move charge on second card !) soon saw the lesser Russian mounted implode almost completely !
Russian foot had several decent volleys pushing back leading lines of Prussians but their follow up units hit Russians hard especially in center and things quickly looked bleak for them.
With several units destroyed or routing the Russian army morale plummeted (start at 30) and they were 'gifting' morale to Prussians and pain ended on an Army Morale card as they yielded (Prussians started with 35 morale lost 13 but gained 12 for a major victory).
I played this for couple of hours late Saturday after watching football (Euros have been entertaining overall so far) and completed game today in another couple of hours with 50 units in action on table (23 Russian and 27 Prussian).
Super stuff as always with FOB and this was a fast and exciting game even with me running from one side of table to other (keeps me fit...................not).
Initial set up (almost at 'whites of their eyes' range) Prussian on right
