I will follow the path of C.S. Grant and split the battle into phases but not into 2 but 3.
Phase 1 is the Saxon outpost on the Spitze-Berge where 18 Saxon grenadier companies supported by Polish uhlans stood in the way of Du Moulin's Prussian advance guard.
Phase 2 will be the attack on the Saxon army.
Phase 3 will be the attack on the Austrian army.
This is a basic wargame/table-top setting not a photo-shoot.
Hopefully, I will finish the three phases before Xmas.
