When the news reached Athens, even though the actual soldiers who had escaped from the action itself gave a clear report, they for long refused to believe that the armament could have been so utterly destroyed. When, however, they were convinced, they were angry with the orators who had taken part in promoting the expedition—as though they had not voted for it themselves—and they were also enraged at the oracle-mongers and soothsayers and whoever at that time by any practice of divination had led them to hope that they would conquer Sicily.
Everything indeed on every side distressed them, and after what had happened they were beset with fear and utmost consternation. For having lost, both each man separately and as a state, many hoplites and horsemen and the flower of the youth, while they saw none like it left them, they were heavy of heart; and again, seeing no ships in the docks in sufficient number nor money in the treasury nor crews for the ships, they were at the moment hopeless of safety. They thought that their enemies in Sicily would sail with their fleet straight for the Peiraeus, especially as they had won so great a victory, and that their foes at home, now doubly prepared in all respects, would attack them at once with all their might both by land and by sea, and that their own allies would revolt and join them.
