of the Thracian towns and of Perdiccas.
Coming to Athens, Nymphodorus concluded the alliance with Sitalces and
made his son Sadocus an Athenian citizen, and promised to finish the
war in Thrace by persuading Sitalces to send the Athenians a force of
Thracian horse and targeteers. He also reconciled them with Perdiccas,
and induced them to restore Therme to him; upon which Perdiccas at
once joined the Athenians and Phormio in an expedition against the
Chalcidians. Thus Sitalces, son of Teres, King of the Thracians, and
Perdiccas, son of Alexander, King of the Macedonians, became allies of
Athens.

Meanwhile the Athenians in the hundred vessels were still cruising round
Peloponnese. After taking Sollium, a town belonging to Corinth, and
presenting the city and territory to the Acarnanians of Palaira, they
stormed Astacus, expelled its tyrant Evarchus, and gained the place for
their confederacy. Next they sailed to the island of Cephallenia and
brought it over without using force. Cephallenia lies off Acarnania and
Leucas, and consists of four states, the Paleans, Cranians, Samaeans,
and Pronaeans. Not long afterwards the fleet returned to Athens. Towards
the autumn of this year the Athenians invaded the Megarid with their
whole levy, resident aliens included, under the command of Pericles, son
of Xanthippus. The Athenians in the hundred ships round Peloponnese
on their journey home had just reached Aegina, and hearing that the
citizens at home were in full force at Megara, now sailed over and
joined them. This was without doubt the largest army of Athenians ever
assembled, the state being still in the flower of her strength and yet
unvisited by the plague. Full ten thousand heavy infantry were in
the field, all Athenian citizens, besides the three thousand before
Potidaea. Then the resident aliens who joined in the incursion were
at least three thousand strong; besides which there was a multitude of
light troops. They ravaged the greater part of the territory, and then
retired. Other incursions into the Megarid were afterwards made by
the Athenians annually during the war, sometimes only with cavalry,
sometimes with all their forces. This went on until the capture of
Nisaea. Atalanta also, the desert island off the Opuntian coast, was
towards the end of this summer converted into a fortified post by the
Athenians, in order to prevent privateers issuing from Opus and the rest
of Locris and plundering Euboea. Such were the
