If you are attacking and he's on a good hill its tough, you might have to split your army into the anvil and hammer, the major part (anvil) goes up on one side of his army, with the archers in a large wedge behind the spears (more archer units on top, still in three or four deep lines). And the HA (if you have them) behind or flanking, with Heavy Cav (hammer) moving to get behind the enemy. If you can kill off his archer units before you move your anvil against his army you will do much better, then charge with your ha/hc into the rear of his army, preferrably into one of his decent units that are ready to break.

You may want to send out a bait force to encourage some of his more impetuous units to chase them back to your lines.
