Celts started lively (they had a plan) and moved towards the Persian infantry getting into javelin range on the first turn.
Persians struggled to form a firing line with so many missile units.
Celts could not string 2 orders together and missed the opportunity to attack, war band initiatives sending in odd units which hit lights and ground to a halt in front of the main Persian line.
Persian cavalry won it by charging on mass into a brigade of war bands and destroying it
Celt cavalry (4units)didn't make their presence felt
