Alcibiades said that a great expedition like the present must not disgrace itself by going away without having done anything; heralds must be sent to all the cities except Selinus and Syracuse, and efforts be made to make some of the Sicels revolt from the Syracusans, and to obtain the friendship of others, in order to have corn and troops; and first of all to gain the Messinese, who lay right in the passage and entrance to Sicily, and would afford an excellent harbour and base for the army. Thus, after bringing over the towns and knowing who would be their allies in the war, they might at length attack Syracuse and Selinus; unless the latter came to terms with Egesta and the former ceased to oppose the restoration of Leontini.
