Well, this senario is a little retarded. I even making hugh mistakes are always able to win it, as a Marginal victory. To win you need to concentrate your whole cavalry on the north side of the field. I make like that. Put some bays - squadrons close to enemy hussars, and roll rest to line formation to get advantage in movment. Some units are cover this move, so I get concentrate bothe line of cavalry very close. Enemy hussars charge me alone (huge failure) so in next time they have no back up. I surround them and destroyed both. Rest cavalry make advance in the north. Enemy get closer and some units charge me again. During this fight I made 1 mistake and need to repair it pulling my north win to south to protect engagment units. If I hadn't make 2 other mistakes (press finish before add points to leaders in the commands turn, and charge instead to move) I would for sure destroy whole enemy cavalry. This get you 2 things. You fight against cavalry only, second enemy infantry go to face you, and leave the matter of taking any flags ;) even if your cavalry go beaten they will not recive any flag. So it is victory at the end. I lost less than enemy, only 2 units rout, 1 destroyed. Enemy lost 1 destroyed 4-5 surrender, 3 rout.
