There was a snow storm that played a role in the battle, causing the two sides to blunder into combat when the snow began blowing. At the start of each turn , there is a 50% chance the blizzard will impair your army for the turn.
The French had the first turn. They started with most of their army in marching to the battle. Napoleon elected to take the initiative and capture both Eylau hexes and the adjacent graveyard. Murat's cavalry caught the Russian cavalry in column on the French left and pressed forward aggressively.
Hearing the sounds of the battle engaged, the Russian generals left the army HQ to find their units. Seeing the French had moved into range of their guns, the Russian front line opened up a devastating volley causing many casualties. The Russian Grenadiers assaulted and recaptured the graveyard but could not retake Eylau. The Russian left pressed forward against the exposed French right. The Russian cavalry on the right consolidated against the superior French cavalry in the midst.
Napoleon decided to probe the Russian lines for weakness, despite his initial heavy losses. The French light infantry division supported by cavalry broke through to the left of Eylau and drove the Russians back in confusion. The French cavalry attack on the far left had continued success but were starting to risk dispersal due to accumulated losses. Napoleon sent his elite cuirassier unit to shore up the exposed right flank.
Losses after the first game day 12 Russians (including 3 cannon) to 23 French. Stay tuned for part two....
