In the previous year king Croesus of Lydia, impelled by various considerations, invaded the kingdom of Cyrus the Great; he hoped to quell the growing power of Achaemenid Persia; to expand his own dominions; and revenge the deposition of his brother-in-law Astyages; also, he thought himself certain of success, deluded by the ambiguous assurances of the apparently reliable oracle ofApollo at Delphi. , 546 BCE. Croesus crossed the Halys and met Cyrus at Pteria in Cappadocia, but after a drawn-out battle against superior forces in which neither side obtained the victory Croesus resolved to fall back for the winter, summon new allies, and renew the war reinforced in the next spring. In the interim, he disbanded his army and returned to Sardis, expecting Cyrus to hang back after the sanguinary battle in Cappadocia. But the energetic Cyrus, as soon as he heard that Croesus' forces were dispersed, crossed the Halys and advanced with such speed that he had arrived at the Lydian capital, Sardis, before Croesus had any word of his approach. Undaunted, Croesus mustered his available troops and met Cyrus in the battle of Thymbra outside the walls. Cyrus was victorious, having contrived to deprive the Lydians of their last resource, their cavalry, by frightening off their horses with the sight of his camels. The remnants of the Lydian army were driven within the city and promptly besieged.
The Siege
Croesus was still confident in his chances because Sardis was a well-fortified city consecrated by ancient prophecies to never be captured. Additionally, he had sent for immediate aid from Sparta, the strongest state in Greece and his firm ally, and he hoped to enlist the Egyptians, the Babylonians and others in his coalition against Persia as well. In fact, however, the Spartans were then occupied in a war with neighboringArgos, and neither they nor any other of Croesus' allies would assemble in time. Cyrus, meanwhile, stimulated his troops by the offer of large rewards to the first soldiers who should ascend the battlements; but repeated Persian attacks were repulsed with loss. According to Herodotus, the city ultimately fell by the agency of a Persian soldier, who climbed up a section of the walls which was neither adequately garrisoned, nor protected by the ancient rites which had dedicated the rest of the cities' defenses to impregnability; the steepness of the adjoining ground outside the walls was responsible for this piece of Lydian Hubris. Hyroeades, the Persian soldier, saw a Lydian soldier climbing down the walls to retrieve a dropped helmet, and tried to follow the example. The success of his ascent set the example to the rest of Cyrus' soldiers and these swarming over the exposed wall, the city was promptly taken.
Aftermath
had previously issued orders for Croesus to be spared, and the latter was hauled a captive before his exulting foe. Cyrus' first intentions to burn Croesus alive on a pyre were soon diverted by the impulse of mercy for a fallen foe, and according to ancient versions, by divine intervention of Apollo, who caused a well-timed rainfall. Tradition represents the two kings as reconciled thereafter; Croesus succeeded in preventing the worst rigors of a sack by representing to his captor that it was his, not Croesus' property being plundered by the Persian soldiery. The kingdom of Lydia came to an end with the fall of Sardis, and her subjection was confirmed in an unsuccessful revolt in the following year, promptly crushed by Cyrus' lieutenants. The Aeolian and Ionian cities on the coast of Asia-Minor, formerly tributaries of Lydia, were likewise conquered not long after, establishing the circumstances for Greco-Persian animosity, which would last till the outbreak of the Persian Wars in the succeeding century. There was a second siege of Sardis, in 498 BC, during the Ionian Revolt.
