 However, according to Herodotus, a wild boar began to ravage the neighboring province of Mysia, which soon begged Croesus to send a military expedition led by Atys to kill the boar.Croesus thought this would be safe for his son, as Atys would not be fighting an enemy that could throw a spear.However, he sent Adrastus with Atys as a bodyguard in case they might be waylaid by bandits on the expedition.
