I have a normal arrangement. Spears, Swordman, Archers and Cav. I have about 2 units of Spears to protect my archers then about 4-5 longbow units (I play the English A LOT too) then my Swordman (how ever many I want ) then a general unit and 3-4 Cav. units. With the Cav. if its very hilly terrain I like to take one or two units the long way around the battle field so I can really pull a flank. Thats about it.
