When Cyrus saw the Lydians maneuvering their battle-lines here, he was afraid of their cavalry, and therefore at the urging of one Harpagus, a Mede, he did as I shall describe. Assembling all the camels that followed his army bearing food and baggage, he took off their burdens and mounted men upon them equipped like cavalrymen; having equipped them, he ordered them to advance before his army against Croesus' cavalry; he directed the infantry to follow the camels, and placed all his cavalry behind the infantry.

When they were all in order, he commanded them to kill all the other Lydians who came in their way, and spare none, but not to kill Croesus himself, even if he should defend himself against capture.

Such was his command. The reason for his posting the camels to face the cavalry was this: horses fear camels and can endure neither the sight nor the smell of them; this then was the intention of his maneuver, that Croesus' cavalry, on which the Lydian relied to distinguish himself, might be of no use.

So when battle was joined, as soon as the horses smelled and saw the camels they turned to flight, and all Croesus' hope was lost.

Nevertheless the Lydians were no cowards; when they saw what was happening, they leaped from their horses and fought the Persians on foot. Many of both armies fell; at length the Lydians were routed and driven within their city wall, where they were besieged by the Persians.
