During the same summer the Lacedaemonians and their allies made an expedition with a hundred ships against Zacynthus, an island lying off the coast of Elis, peopled by a colony of Achaeans from Peloponnese, and in alliance with Athens. There were a thousand Lacedaemonian heavy infantry on board, and Cnemus, a Spartan, as admiral. They made a descent from their ships, and ravaged most of the country; but as the inhabitants would not submit, they sailed back home.
At the end of the same summer the Corinthian Aristeus, Aneristus, Nicolaus, and Stratodemus, envoys from Lacedaemon, Timagoras, a Tegean, and a private individual named Pollis from Argos, on their way to Asia to persuade the King to supply funds and join in the war, came to Sitalces, son of Teres in Thrace, with the idea of inducing him, if possible, to forsake the alliance of Athens and to march on Potidaea then besieged by an Athenian force, and also of getting conveyed by his means to their destination across the Hellespont to Pharnabazus, who was to send them up the country to the King. But there chanced to be with Sitalces some Athenian ambassadors- Learchus, son of Callimachus, and Ameiniades, son of Philemon- who persuaded Sitalces'
son, Sadocus, the new Athenian citizen, to put the men into their hands and thus prevent their crossing over to the King and doing their part to injure the country of his choice. He accordingly had them seized, as they were travelling through Thrace to the vessel in which they were to cross the Hellespont, by a party whom he had sent on with Learchus and Ameiniades, and gave orders for their delivery to the Athenian ambassadors, by whom they were brought to Athens. On their arrival, the Athenians, afraid that Aristeus, who had been notably the prime mover in the previous affairs of Potidaea and their Thracian possessions, might live to do them still more mischief if he escaped, slew them all the same day, without giving them a trial or hearing the defence which they wished to offer, and cast their bodies into a pit; thinking themselves justified in using in retaliation the same mode of warfare which the Lacedaemonians had begun, when they slew and cast into pits all the Athenian and allied traders whom they caught on board the merchantmen round Peloponnese.
Indeed, at the outset of the war, the Lacedaemonians butchered as enemies all whom they took on the sea, whether allies of Athens or neutrals.
About the same time towards the close of the summer, the Ambraciot forces, with a number of barbarians that they had raised, marched against the Amphilochian Argos and the rest of that country. The origin of their enmity against the Argives was this. This Argos and the rest of Amphilochia were colonized by Amphilochus, son of Amphiaraus. Dissatisfied with the state of affairs at home on his return thither after the Trojan War, he built this city in the Ambracian Gulf, and named it Argos after his own country. This was the largest town in Amphilochia, and its inhabitants the most powerful.
