If Crœsus really began the war, he assuredly did so not frivolously but deliberately, in order to anticipate the inevitable attack. A fierce struggle seems to have taken place in Cappadocia (Herod., I, 76, and especially Polyænus, VII, 8, 1
The date of Crœsus’ fall is not quite certain. It may have been 547 or 546. When Cyrus had marched away, the Lydian Pactyas, whom Cyrus had appointed guardian of the treasures, raised a revolt, but it was speedily put down by the king’s generals. From that time forwards the Lydians never made the slightest attempt to shake off the Persian rule.
But now began that struggle of the Persians with the Greeks which has had so much importance for the history of the world. The Lydian kings had subdued a number of Greek cities in Asia Minor; but even these latter shrank from submitting to the still barbarous Persians, whose rule was far more oppressive, inasmuch as they ruthlessly required military service. But Harpagus, and other Persian leaders, quickly took one Greek town after the other; some, like Priene, were razed to the ground. Some of the Ionians, such as the Teians, and most of the Phocæans, avoided slavery by emigrating. Miletus alone, the most flourishing of all these cities, had early come to an understanding with Cyrus, and the latter pledged himself to lay no heavier burden on it than Crœsus had before him. In most of the cities the Persians seem to have set up tyrants, who gave them a better guarantee of obedience than democratic or aristocratic governments. In other respects they left the Greeks alone, just as they left their other subjects alone, not meddling with their internal affairs so long as they paid the necessary contributions, and supplied men and ships for their wars. Most of the other peoples in the west of Asia Minor submitted without much resistance, except the freedom-loving Lycians. Driven into Xanthus, the capital, they perished in a body rather than surrender. Some Carian cities also defended themselves stoutly. This may have given a Persian here and there an inkling, even then, that the little peoples on the western sea were, after all, harder to manage than the nations of slaves in the interior of Asia. Sardis became and remained the mainstay of the Persian rule in western Asia Minor. The governorship was one of the most influential posts in the empire, and the governor seems to have exercised a certain supremacy over some neighbouring governorships.
