I know, these moslim sword and spear are normally superior to others. Very hard to beat.
I always try to let them attack me and fight defensive battle against them (the roman tactic). Make sure I wear them out before they get to me. I use two or three good long range archer units and target their general (or elite units). If you kill the general they will break sooner or later. Once my archers are done I move in more sword units.
Outflank them and attack in their back with cavalry after all their infantry is involved in melee.

It's hard to beat these dudes.
Several times I have given up the battle and retreated (in orderly conduct ). Then attacked again in other turn, slowly wearing them out.

This is actually what I enjoy in games: the challenge to find a way to win. You have about 500 years to do that with Redux.

Maybe Axalon should give out prizes . Like a date with one of the princesses after beating the Moors or Saracens .
