The French left at the end of the 20:00 turn.
Note the Prussians are back in Wagnelee and Le Hameau.
The French right.
Gerard's IV Corps is fatigued.
The 20:00 turn had seen a period of consolidation with the French firmly across the Ligny brook.
But then they struck west.
But then they struck west.
Vandamme leads the attack on Wagnelee and Le Hameau.
Morand cheers on his men as the Chasseurs a Pied of the Old Guard smash into the remaining Prussians of I Korps.
Even intervention by Prussian hussars couldn't stop the French Old Guard.
(It was a disaster as the disordered Prussian infantry was the modifying unit).
End of the 20:30 turn from the Prussian left hand side.
The Prussians hope to wear down the French in a long range fire fight.
And from the Prussian right.
Vandamme's III Corps is now fatigued, but he has taken Wagnelee and Le Hameau.
At this stage the French need to disperse about four Prussian units to break their morale. The French morale will fail if they lose one or two of the Old Guard infantry units.
The final assault.
The Young Guard and Guard Heavy cavalry are committed en masse,
with a bit of help from the Old Guard Grenadiers.
It's all over.
Milhaud's heavy cavalry are ready to put in a pursuit, but night is falling. Prussian morale has broken. Of the four French Old Guard units, one was 1 casualty away from dispersing (but Milhaud's cavalry could move to screen it). The French still had one Free Roll. The other Old Guard units were 5 and 6 casualties away from dispersing. They had wisely kept out of range of Prussian firing.
The French held Wagnelee and Le Hameau which had changed hands so many times.
The Prussians held St Amand le Haye.
The battery was way too powerful with it's all round fire for only a -1 penalty. I'm now of the opinion that built up areas are no place for the horse and heavy artillery batteries as depicted in Napoleon's Battles.
Half of St Amand is still in Prussian hands.
I was happy with the BUA rules (which is good as I'd put a bit of work into them). The challenge remains to get the footprint right and their terrain effects stated. This I maintain is more for the scenario than the rules themselves as villages and their surrounding terrain vary widely between battlefields I am sure.
Ligny itself.
The two forward segments had seen their occupants dispersed after a long day's fighting. The French, with just four small brigades in the IV Corps quickly ran out of troops in trying to combat this village.
I had left out the 9th Prussian brigade which was part of II Korps. From my reading it only came in late to help with the retreat.
The arrival of the French 4th Division didn't do much (one brigade was dispersed by fire from the western segment of St Amand and the other one held to other half of St Amand, but didn't launch any attacks).
The stream, representing one inch of rough terrain, caused delay, but was not a significant factor in combat (as in no units won or lost because of fighting in the stream, but plenty of units couldn't immediately get into action because of the stream). Artillery could only cross limbered at the BUAs, infantry had to be in column, but cavalry could cross regardless of formation (their formations tend to be deeper and their rough penalty movement factor is high, it generally took a full move for cavalry to cross).
The French tended to crowd together and this was impacted by their abundance of commanders. Adjusting the placement of generals after other movement had been completed, but before enemy recat phase, worked well, but I still think a general displacement rule is needed as they still caused blockages.
Optional rules from the 4th Edition that we used and I thought worked well were the self command and self rally. With those two rules I would be comfortable see commanders displaced being off the table for one move.
