When I "sallied" from my home hill, I found I was taking unacceptable hoplite casualties even from the front. A combination of the enemy height advantage and cross-fire from other hills.

Oh... I think I was playing on H/H as well which didn't help matters. I won't be doing that again after having a siege tower arrive completely empty at the enemy walls with a trail of Spartan corpses behind it (slingers + height = )
