The hieght advantage is always a very important factor my friend!...A good high Position Gives YoU a bonus in ThE moral of your MeN, This Bonus is ThE difference between your MeN AnD your Enemy... BuT u CaN UsE it against your enemy ToO...many think that they ArE safe in a High HILL, well in the books of Sunt Tzu its named the FLOW, its says that u dont have to mantain a Formation but that u have to move your troops accord to the Terrain. Like a river goes with the way!... so if one enemy is on a hill u must try to go higher as him!... use the flanks ... if ur troops atack from Down use a FALSE FRONT...send units in a line... to contain the atack of the defenders... then send to the flanks the res of army but try to get higher as him!...
I hope it can help you... may be i ll post a new reply later with graphics so u can look it!...
have nice day...
