Lydian Empire and Asia Minor
The exact dates of the Lydian conquest are unknown, but it must have taken place between Cyrus' overthrow of the Mede kingdom (
550 BC)) and his conquest of Babylon (
539 BC). It was common in the past to give
547 BC as the year of the conquest due to some interpretations of the
Nabonidus Chronicle, but this position is currently not much held. The Lydians first attacked the Achaemenid Empire's city of
Pteria in
Cappadocia. Croesus laid siege to the city, and captured its inhabitants as slaves. Meanwhile, The Persians invited the citizens of
Ionia, who were part of the Lydian kingdom, to revolt against their ruler. The offer was rebuffed, and thus Cyrus levied an army and marched against the Lydians, increasing his numbers while passing through nations in his way. The
Battle of Pteria was effectively a stalemate, with both sides suffering heavy casualties by nightfall. Croesus retreated to Sardis the following morning.
While in Sardis, Croesus sent out requests for his allies to send aid to Lydia. However, near the end of winter, before the allies could unite, Cyrus pushed the war into Lydian territory and besieged Croesus in his capital,
Sardis. Shortly before the final
Battle of Thymbra between the two rulers, Harpagus advised Cyrus to place his
dromedaries in front of his warriors; the Lydian horses, not used to the dromedaries' smell, would be very afraid. The strategy worked; the Lydian cavalry was routed. Cyrus defeated and captured Croesus. Cyrus occupied the capital at Sardis, conquering the Lydian kingdom in 546 BC. According to Herodotus, Cyrus spared Croesus' life and kept him as an advisor, but this account conflicts with some translations of the contemporary Nabonidus Chronicle, which interpret that the king of Lydia was slain.
Before returning to the capital, a Lydian named Pactyes was entrusted by Cyrus to send Croesus' treasury to Persia. However, soon after Cyrus' departure, Pactyes hired mercenaries and caused an uprising in Sardis, revolting against the Persian
satrap of Lydia, Tabalus. With recommendations from Croesus that he should turn the minds of the Lydian people to luxury, Cyrus sent
Mazares, one of his commanders, to subdue the insurrection, but demanded that Pactyas be returned alive. Upon Mazares' arrival, Pactyas fled to
Ionia, where he had hired mercenaries. Mazares marched his troops into the
Greek country and captured the cities of
Magnesia and
Priene, where Pactyas was captured and sent back to Persia for punishment.
Mazares continued the conquest of Asia Minor, but died of unknown causes during his campaign in Ionia. Cyrus sent Harpagus to complete Mazares' conquest of Asia Minor. Harpagus captured
Lycia, Cilicia and
Phoenicia, using the technique of building
earthworks to breach the walls of besieged cities, a method unknown to the Greeks. He ended his conquest of the area in 542 BC, and returned to Persia.
