To a certain extent also the affairs of the enemy, judging from what he, more than others, knew of them, still afforded some hope that they would be worse than their own, should they persist in carrying on the siege; for so they would exhaust them by want of funds; especially, too, as they had now, with their present fleet, a more extensive command of the sea. A party in Syracuse also, which wished to surrender the city to the Athenians, was sending messengers to him, and urging him not to raise the siege. Knowing these things, then, he was in fact waiting because he was still inclined both ways, and wished to see his course more clearly;
but in the speech openly made by him on that occasion he said,
that he refused to withdraw the forces; for he well knew that the Athenians would not put up with such a step on the part of the generals—their returning, he meant, without a vote from themselves to authorize it. Besides, those who would vote in their case, would not give their verdict from seeing the facts, as they themselves had done, instead of hearing them from the invectives of others; but whatever calumnies any clever speaker threw upon them, by those would they be persuaded. Many too, nay, even the greater part of the soldiers present on the spot, who were now clamouring about their perilous condition, would, he said, on arriving there, raise the very contrary clamour, namely, that their generals had utterly betrayed them for money, when they returned.
