The result is a French major victory. The Prussians did better than in 1806. They avoided a total defeat as happened in the real campaign, but still suffered a major defeat. The Prussian condition for this level of defeat was ‘You cut and run, getting over half your army away across the Elbe.’ This is what occurred by day 11, but the Prussian army is in better shape and held out longer than I expected.
The Prussian King had insisted the Prussians fight a battle before conceding the line Gera-Jena-Sommerda. The battle of Gera released them from this obligation and they were now free to manoeuvre as their CinC wished.
