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.
