Unplayable Napoleonics Scenario

The challenges posed by this completely unplayable scenario were exacerbated by the sheer bloody-minded incompetence of the respective commanders!!

Joking aside, this was actually a really enjoyable scenario which posed the French versus the Spanish, who faced off against each other across some very rough terrain of hills and woods which represented 'difficult going' and cover. 

Eventually the Spaniards forced their way across the intervening terrain more effectively to deliver several knock-out blows, which forced a couple of French units to rout, setting off a domino effect amongst the French units, leading to the collapse of the entire army. It should be pointed out that the Spanish had an extra battalion, for some unexplained reason, so this might have helped. Also the author of the scenario was commanding on the Spanish side, so this might have explained the 'thumb on the scale', as it were....
