No, but you stated that the Prussians at Ligny were set up to shatter.
Just the units in the single hex of Ligny. Not the entire Prussian force in the Battle of Ligny.
I took a look. Two of the three Prussian corps commanders at Ligny;
"From the field of Ligny he retired with the rest of Blücher's army on Wavre, and when the other corps marched towards Waterloo, Thielmann covered this movement against Grouchy, fighting the spirited action of Wavre (18-19 June 1815)"
"Lieutenant-General Graf von Zieten commanded the Prussian I Corps. He Corps fought a holding action against the French on 15 June, and was heavily engaged against the French the next day at the Battle of Ligny and then again two days later on June 18 at the Battle of Waterloo."
Unless these two men abandoned their (intact) corps, both corps were evidently capable of heavy fighting. Anyway, the campaign map of the battle itself shows Zieten's I Corps coming into the battle.
So, in other words, you would have been blindsided by the Prussians too (if you hadn't read the AAR). Exellent! I'm sure plenty of other players could fall in the same trap. They'll think they have them under control by Grouchy, and - bam! - get hit by Bulow.
At Waterloo, it was primarily the Bulow and the IV Corps that got there first and caused the problems. They weren't at Ligny. Some elements from Ligny did get there, and, if the French player is less successful at Ligny, some of them could in the game too. III Corps (Thielmann) is probably best positioned to do so, being in the rear.
provided you bear in mind that it doesn't bear any relation to historical reality ...
It bears a lot of relation to historical reality. It's range of possible outcomes straddle the historical range of possibilities. That in itself says I got a lot right. Lots of WWII scenarios would like to do as well. Your claims to the contrary, the forces function very much like Napoleonic ones would, operationally. The players are given operational choices that Napoleon would have had to make (what forces to devote to the two axes, when and whether to shift forces between them, how to marshall his forces to break the enemy etc.)
I bet you he could. It's about five hexes and he could screen the Prussians with a few divisions.
But he can't wait until the day of Waterloo to do so. It's too far by then. So he wouldn't get any head start from knowing Napoleon's situation on that day.
But Napoleon will still know Grouchy's situation- even if you get a martian to play.
So what? How long did it take him to figure out that those people on his flank were Prussians and not Grouchy?
And just what sort of game is there out there in which the French player doesn't know what's happening with both situations? And who would want it if there was?
