“Personal imputations it is not wise either for any speaker to utter against another or for those who hear to tolerate; but in view of the reports that are coming in, we should rather see how we, each person and the city as a whole, shall prepare to defend ourselves effectively against the invaders.
And if after all there shall be no need of it, there is no harm in the commonwealth being equipped with horses and arms
and all other things wherein war takes pride—the provision and inspection of such equipment we shall have in charge—and in sending men round to the cities for observation as well as for any other purpose that may seem expedient. These provisions we have in part already made, and whatever we find out we will bring before you.” And the Syracusans, when the general had said thus much, dispersed from the assembly.
Meanwhile the Athenians themselves and all their allies also were already at Corcyra. And first the generals held a final review of the armament and made disposition in what order the forces were to anchor and to encamp. Making three divisions they allotted one to each general, in order that they might not, by sailing together, be at a loss for water and ports and provisions when they put in to shore, and that they might in general be more orderly and easy to control, being thus assigned in divisions to separate commanders.
And next they sent forward to Italy and Sicily three ships, to ascertain which of the cities would receive them. And orders were given to these ships to come back to meet them, that they might know before putting to shore.
