Its quite incredible that such a large battle was never recorded by the Napoleonic era historians but thank goodness that Steve C has re-enacted this in his War Room over the last few days.
The French are on the defensive as an aggressive Prussian force under Blucher attempts to break the Emperor's field army, in the full knowledge that a strong Austrian army was also rapidly advancing.
Sheer weight of numbers means the French have to break off and retrieve as many of their units as possible. The Allies have won !
Black Powder solo by Steve spread out over six days. Quite a feat !
