The Thebans, whose general was Leontiades, fought against the king's army as long as they were with the Hellenes and under compulsion. When, however, they saw the Persian side prevailing and the Hellenes with Leonidas hurrying toward the hill, they split off and approached the barbarians, holding out their hands. With the most truthful words ever spoken, they explained that they were Medizers, had been among the first to give earth and water to the king, had come to +Thermopylae [22.5583,38.8] (Perseus) Thermopylae under constraint, and were guiltless of the harm done to the king.

By this plea they saved their lives, and the Thessalians bore witness to their words. They were not, however, completely lucky. When the barbarians took hold of them as they approached, they killed some of them even as they drew near. Most of them were branded by Xerxes command with the kings marks, starting with the general Leontiades. His son Eurymachus long afterwardsIn 431; cp. Thuc. 2.2 ff. was murdered by the Plataeans when, as general of four hundred Thebans, he seized the town of Plataea [23.2667,38.2] (Perseus) Plataea.
