Mike's French corps was based on Sebastiani's IV Corps with 2 infantry divisions, one French & one mostly Germans, each 2 brigades of 4 units & a cavalry division of two 3 unit brigades, one hussar & 1 chasseur, plus 4 batteries.
Steve's Spanish army was based on Venagas' Army of the Centre with 4 infantry divisions, each with 6 units, a light cavalry division of 4 units & a heavy cavalry division of 4 units, & 4 batteries. We had to substitute Austrians for the Spanish army, but who knows or cares what the Spanish looked like anyway?
The H-T-H ratings of the infantry were 4 for the French & 3 for the Germans & Spanish. The shooting ratings were 4 for the French & Allies, 3 for the Spanish. The Spanish heavy cavalry & the French hussars had H-T-H 5, the chasseurs 4 & the Spanish light horse 3. The command ratings were 9 for French brigades, 8 for German brigades & Sebastiani & 7 for the Spanish brigades & Venagas. The Spanish infantry were also poorly trained. For all the Spanish troops Break if Shaken results were Break if Spanish. So the Spanish units were severely handicapped, but they had 36 units to 26.
We declared nightfall at that point with the Spanish losing 2 divisions out of 6 & the French no brigades out of 6. Technically a draw, but in a campaign situation the Spanish would, given their losses, almost certainly withdraw overnight rather than risk complete rout next day. My analysis is that Sebastiani erred in his initial deployment in that he should have put his best troops in the open ground on his left to make the attack. They had a good chance of breaking the Spanish right quickly & then rolling up the Spanish line, while the Germans would have easily have pinned down the Spanish left. As it was, after initial setbacks the Grman infantry were fortunate to hang on until the cavalry could turn the tide.
The Spanish rules seemed to have the right effect. The Spanish looked scary with so many troops & sheer numbers give them lots of dice to throw at the enemy, but large divisions & poor command makes decisive maneouvre difficult for them & the Break if Spanish rule gives them an unpredictable vulnerability that feels right.
