History of the Peloponnesian War

Summer was now over. The winter following, the Athenians at once began to prepare for moving on Syracuse, and the Syracusans on their side for marching against them.

From the moment when the Athenians failed to attack them instantly as they at first feared and expected, every day that passed did something to revive their courage; and when they saw them sailing far away from them on the other side of Sicily, and going to Hybla only to fail in their attempts to storm it, they thought less of them than ever, and called upon their generals, as the multitude is apt to do in its moments of confidence, to lead them to Catana, since the enemy would not come to them.

Parties also of the Syracusan horse employed in reconnoitring constantly rode up to the Athenian armament, and among other insults asked them whether they had not really come to settle with the Syracusans in a foreign country rather than to resettle the Leontines in their own.

Aware of this, the Athenian generals determined to draw them out in mass as far as possible from the city, and themselves in the meantime to sail by night along shore, and take up at their leisure a convenient position. This they knew they could not so well do, if they had to disembark from their ships in front of a force prepared for them, or to go by land openly. The numerous cavalry of the Syracusans (a force which they were themselves without), would then be able to do the greatest mischief to their light troops and the crowd that followed them; but this plan would enable them to take up a position in which the horse could do them no hurt worth speaking of, some Syracusan exiles with the army having told them of the spot near the Olympieum, which they afterwards occupied. In pursuance of their idea, the generals imagined the following stratagem.

They sent to Syracuse a man devoted to them, and by the Syracusan generals thought to be no less in their interest; he was a native of Catana, and said he came from persons in that place, whose names the Syracusan generals were acquainted with, and whom they knew to be among the members of their party still left in the city.
