History of the Peloponnesian War

After this brief speech, Brasidas himself prepared for the sally and placed the rest with Clearidas at the gate called Thracian, in order that they might come out to his support according to his orders.

But he had been seen when he came down from Cerdylium, and again in the city—which is in full view from outside—while sacrificing at the temple of Athena and busied about these matters; and word was brought to Cleon, who had gone forward at that time for the reconnaissance, that the whole army of the enemy could be clearly seen inside the city, and the feet of men and horses in great numbers were visible under the gates, as though ready for a sally.

Hearing this Cleon came nearer; and when he saw it, being unwilling to risk a battle before his reinforcements arrived, and thinking that he could get away in time, he gave orders to sound a retreat and at the same time passed along word to the troops as they set off to go to the left —as alone was possible—upon the road to Eion.
