He persuaded the Lacedaemonians, by pledging them his faith, that, if they would not admit before the assembly that they had come with full powers, he would restore Pylos to them—for he himself would use his influence with the Athenians for them as now he opposed them— and would settle the other points at issue.

He resorted to such methods because he wished to detach them from Nicias, and in order that he might accuse them before the assembly of having no sincere intentions and of never saying the same things, and thereby might effect an alliance with the Argives, Mantineans, and Eleans.

For when, on coming before the popular assembly and being asked whether they had come with full powers, they answered “No,” contrary to what they had said in the senate, the Athenians could endure it no longer, but hearkened to Alcibiades, who inveighed against the Lacedaemonians far more than before, and were ready at once to bring in the Argives and their confederates and conclude an alliance. But before anything was ratified an earthquake occurred, and this assembly was adjourned.
