The same summer the Dians took Thyssus, a town on Acte by Athos in alliance with Athens.

During the whole of this summer intercourse between the Athenians and Peloponnesians continued, although each party began to suspect the other directly after the treaty, because of the places specified in it not being restored.

Lacedaemon, to whose lot it had fallen to begin by restoring Amphipolis and the other towns, had not done so. She had equally failed to get the treaty accepted by her Thracian allies, or by the Boeotians or the Corinthians; although she was continually promising to unite with Athens in compelling their compliance, if it were longer refused. She also kept fixing a time at which those who still refused to come in were to be declared enemies to both parties, but took care not to bind herself by any written agreement.

Meanwhile the Athenians, seeing none of these professions performed in fact, began to suspect the honesty of her intentions, and consequently not only refused to comply with her demands for Pylos, but also repented having given up the prisoners from the island, and kept tight hold of the other places, until Lacedaemon's part of the treaty should be fulfilled.

Lacedaemon, on the other hand, said she had done what she could, having given up the Athenian prisoners of war in her possession, evacuated Thrace, and performed everything else in her power. Amphipolis it was out of her ability to restore; but she would endeavor to bring the Boeotians and Corinthians in to the treaty, to recover Panactum, and send home all the Athenian prisoners of war in Boeotia.

Meanwhile she required that Pylos should be restored, or at all events that the Messenians and Helots should be withdrawn, as her troops had been from Thrace, and the place garrisoned, if necessary, by the Athenians themselves.
