The combat power of the French cavalry (the other nations I have not checked) is not correct.
For example the combat power of a brigade (two elements) of French heavy cavalry (cuirassiers or carabiners) is 13 points, and the combat power of a brigade of light cavalry (Chasseurs o chasseur?- hussars?) 28 points.
I think attribute Cbt. Power of the heavy cavalry is incorrect. In heavy cavalry put weak and the light cavalry put average.
