People seem to think that Cavalry are weak but with the exception of Henry V's machine gunners, they are one of the most powerful units in the game. In the Demo if you hit a unit in combat in the side with a cavary charge they break, everytime and suffer 50% casulties, that is probably realistic and providing you are sensible and use infantry to fix enemy units Cavalry can still be battle winners and the core of your army. They just need a bit of help. A Cavalry heavy French army is not going to be difficult to win with!
