I was playing a few turns as the Saxons, just to see what they could do, when I was attacked by the Celts in Northern England.
As my Keelmen stood waiting in their shieldwall, a unit of Hounds of Chulain (sp?) advanced with the rest the Celtic army, but one of those brave berserkers felt like he needed to prove something apparently: he ran forward, to stand just before my battleline alone, shouting at my Keelmen, waving his weapons etc. I couldn't attack him, because the rest of the unit was still out of range for my archers, and I didn't want to mess up my shield wall.
But it looked really cool, one man shouting and cursing at a couple of hundred before him!!!
