There must have been some urgent necessity which summoned Cyrus to the East before he subjected the Lydians, Carians, and Greeks of the coast. Herodotus tells us that he intended to conquer Babylon, the Bactrian nation, the Sacæ and Egyptians. In the early spring he set out with the bulk of his army to Ecbatana.[34] Croesus was in his train. He had given the government of Lydia to Tabalus, a Persian, but the management of the revenues to Pactyas, a Lydian.[35] He may have thought that Lydia was more peaceable than it really was, or more reconciled to its fate by his gentle treatment of Croesus, and the nomination of a Lydian as manager of the taxes. The dominion of the Persians had come upon the Lydians suddenly; they refused to recognise the superior power of their rulers, and could not finally accept the rapid change which had so suddenly overthrown their ancient kingdom and their fame in arms. So far from being subdued, they hardly considered themselves seriously beaten. The rapid and decisive action, in which they had been defeated, might appear to them rather a fortunate surprise, than a victory won by the Persians. It was Pactyas, whom Cyrus had made manager of the revenues, who raised the standard of revolt. He collected the Lydians, and induced the inhabitants of the coast, i.e. the cities of the Greeks, to join him. Tabalus could not resist in the open field the sudden outburst of rebellion. When Pactyas marched against Sardis, he was compelled to shut himself up in the citadel, and was there besieged. While yet on his march Cyrus received the news of the revolt. Yet his presence in upper Asia was so necessary that he did not return in person; he sent Mazares, a Mede, with a part of the army, to bring the Lydians once more to obedience. The rebellion appears to have been undertaken in haste without sufficient preparations, and Pactyas was not the man to lead it with energy. He did not venture to await the arrival of Mazares; the citadel of Sardis was delivered; Tabalus was free; the rebellion was crushed; Pactyas fled to the Greeks on the coast, to Cyme, the leading city of the Aeolians. When Mazares demanded that he should be given up, the oracle of Apollo at Miletus twice ordered the Cymæans, in answer to their repeated inquiry, to surrender him. The priests of that temple, the Branchidæ, well knew that the arrangement which their city had made with Cyrus, pledged her to carry out the wishes of the Persians. The Cymæans did not obey even the second response, but first took Pactyas in safety to Mytilene in Lesbos, and when they found that the Mytileneans were ready to give him up, they took him to Chios. But the Chians, though, like the Lesbians, they had nothing to fear from the Persians in their island, nevertheless surrendered him.[36]
