Soon after the rebellion against Dionysius, the Persian fleet moved to attack the Ionians, who sailed out to meet them. The Samian contingent hoisted their sails, as had been agreed, and fled the battlefield. However, 11 Samian ships refused to desert the other Ionians, and remained at the battle. Seeing the Samians leave, their neighbours on the western wing, the Lesbians, also fled. The whole west-wing of the Ionian battle line thus very quickly collapsed. Other Ionian contingents also fled as the situation became more desperate.
