Scarcely, however, was he departed when Sardis became the scene of an insurrection. Pactyas, a Lydian, who had been entrusted with the duty of conveying the treasures of Croesus and his more wealthy subjects to Ecbatana, revolted against Tabalus, the Persian commandant of the town, and being joined by the native population and numerous mercenaries, principally Greeks, whom he hired with the treasure that was in his hands, made himself master of Sardis, and besieged Tabalus in the citadel. The news reached Cyrus while he was upon his march; but, estimating the degree of its importance aright, he did not suffer it to interfere with his plans. He judged it enough to send a general with a strong body of troops to put down the revolt, and continued his own journey eastward. Mazares, a Mede, was the officer selected for the service. On arriving before Sardis, he found that Pactyas had relinquished his enterprise and fled to the coast, and that the revolt was consequently at an end. It only remained to exact vengeance. The rebellious Lydians were disarmed. Pactyas was pursued with unrelenting hostility, and demanded, in succession, of the Cymaeans, the Mytilenseans, and the Chians, of whom the last-mentioned surrendered him. The Greek cities which had furnished Pactyas with auxiliaries were then attacked, and the inhabitants of the first which fell, Priene, were one and all sold as slaves. Mazares soon afterwards died, and was succeeded by Ha-pagus, another Mede, who adopted a somewhat milder policy towards the unfortunate Greeks. Besieging their cities one by one, and taking them by means of banks or mounds piled up against the walls, he, in some instances, connived at the inhabitants escaping in their ships, while, in others, he allowed them to take up the ordinary position of Persian subjects, liable to tribute and military service, but not otherwise molested. So little irksome were such terms to the Ionians of this period that even those who dwelt in the islands off the coast, with the single exception of the Samians--though they ran no risk of subjugation, since the Persians did not possess a fleet--accepted voluntarily the same position, and enrolled themselves among the subjects of Cyrus.
