Histories

When Croesus marched away after the battle in the Pterian country, Cyrus, learning that Croesus had gone intending to disband his army, deliberated and perceived that it would be opportune for him to march quickly against Sardis [28.0167,38.475] (Perseus) Sardis, before the power of the Lydians could be assembled again.

This he decided, and this he did immediately; he marched his army into Lydia [27.516,38.683] (region (general)), Turkey, Asia Lydia and so came himself to bring the news of it to Croesus. All had turned out contrary to Croesus' expectation, and he was in a great quandary; nevertheless, he led out the Lydians to battle.

Now at this time there was no nation in Asia (continent)Asia more valiant or warlike than the Lydian. It was their custom to fight on horseback, carrying long spears, and they were skillful at managing horses.
