The Legion tried to get tricky and head down one side, thus denying the rebels their full fire power. Indeed, some rebels spent the game criss crossing the table trying to get in the fight.
Deadly fire from the rebel's "Green Die of Doom" quickly brought down more thn a few Legionnaires. But, it was when the Legion stopped to try and duke it out with the rebels on the catina roof that they effectively lost the game.
I'll try this scenario again with equal forces, or give the crack French troops a better bonuses.
