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 with reinforcements the next spring. In the interim, he disbanded his army and returned to Sardis. He expected Cyrus to hang back after the sanguinary battle in Cappadocia, but the energetic Cyrus, as soon as he heard that Croesus's 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.
