In a previous post Marian attach a link to his replay for Las Navas (my solution is more more bloody for player units ). For Campaldino, destroy first the enemy cavalry units without use your which aren't strong, for make this place the pikemen in circle in the middle ahead your cavarly initial placement. THe enemy cavarly trying to charge your one will stop over the circles; now make the others infantry units (swordmen and archers), which must be on the flanks, fall over the enemy cavalry. THe enemy infantry will come lately but at this poijt i should be already destroyed the general and the elite units, so destroy the inf. (now using you cav on the flank and rear) will be a routine work.
