as with most all cavalry scenarios, I think the cavalry unit strength needs to be equal to make the scenario in anyway enjoyable, and in this instance it would mean reducing all the French cavalry to 3 strength units. Gives the Spanish at least equal standing.

I'd also suggest weeding down the Command Deck to remove the 'dead' Command cards

lastly.. the Guerrilla Marker, my least favourite CCN mechanic, and so perverse here.
Michael's suggestion is to give the Spanish the first turn, and I'd suggest that and getting rid of the GM.

Underneath it all, this could be a fun scenario with a bit of mild modification.

This week Tom and I decided to try some Spanish scenarios and were quite taken with the idea of a cavalry battle. Maybe we should have checked the win statistics beforehand.
Anyway, Tom took the French first and promptly instigated a cavalry charge: four French light cavalry left of centre attacking four Spanish light cavalry. When the dust settled, the four French units were still there. Of the Spanish there was no sign.
The French decided to press their luck, the lights advancing to meet Spanish heavy cavalry. This time, one French unit went down, but both Spaniards bit the dust and the Spanish right flank was no more.
Focus now shifted to the centre as the Spanish fought back, removing a second enemy light cavalry unit. There should have been more French casualties, but they chased off the attacking guerillas and disposed of a third Spanish heavy cavalry.
2:7 to Tom and only an hour played. Could I get revenge?
Switching sides, I started by bringing the heavy cavalry into the French line and advancing slowly. The Spanish heavies moved up too.
Then came the charge, left of centre again, and again came the rout of the Spanish, three light cavalry destroyed in exchange for light casualties on the French side.
The Spanish tried to counter-attack with what was left of their right wing, but were pushed back as the French re-grouped. The centre right Spanish units now moved across to tackle the advanced French force and eliminated one light cavalry.
Again thwarting interference from guerillas, the French made the Spanish pay: another three units lost.
The final act was a bold attack by General Rivas and his heavy cavalry. The French heavy cavalry withstood the charge and wiped out his command, Rivas fleeing the battlefield ignominiously.
And that was 7:2 to me and an aggregate draw 9:9.
A fun scenario. If you're playing French.

The main Advantage for the French here is, they start and can, dependent of the Command Cards, attack 3-4 spanish LC´s (all the unsupported first).
So the French have a very good Chance, to weak and/or force to retreat the LC´s
without any battle back.

So i would change the scenario notes and give the French also only 5 cards and let the spanish Player start the game, instead the French.

Or revise the setup and and place the complete LC´s one hex in spanish direction, so the starting French Player cant reach them immediately at start.

Played this using the GM as a banner rather than an action cancel, and the Spanish still lost, but 7-5
