In the Siege of Sardis (547 BCE), the last decisive conflict after the Battle of Thymbra, which was fought between the forces of Croesus of Lydia and Cyrus the Great, Cyrus follows Croesus to his city.

He lays siege to it for 14 days, and then captures it.

The siege is to be known as the final event before Lydia was officially annexed by the Achaemenid Empire.

The Ionians and other Asiatic Greeks revolt against Cyrus, and the revolt is finally put down by his best commander, Harpagus the Mede, in 542 BCE.
