With most of the battles I make, one of the sides was historically at a disadvantage, and this is the side the player takes control of. In case of a reasonably equal battle, I generally cheat slightly and give the AI extra valour (it needs all the help it can get lol ). You can generally see individual armies marked on the setup picture: The name underneath the coloured square is the commander. Saladin also has two armies at the Horns of Hattin.
