 What followed next is not entirely clear, but Heraclius certainly won a crushing victory over Shahrbaraz somewhere in Cappadocia.The key factor was Heraclius' discovery of hidden Persian forces in ambush and responding to this ambush by feigning retreat during the battle.The Persians left their cover to chase the Byzantines, whereupon Heraclius' elite "Optimatoi" assaulted the chasing Persians, causing them to flee.
