History of the Peloponnesian War

Thence coming to Berrhoea, they attempted to take it; but when they could not do it, they turned back and marched towards Potidaea by land. They were of their own number three thousand men of arms, besides many of their confederates, and of Macedonians that had served with Philip and Pausanias, six hundred horsemen.

And their galleys, seventy in number, sailing by them along the coast, by moderate journeys came in three days to Gigonus and there encamped.

The Potidaeans and the Peloponnesians under Aristeus, in expectation of the coming of the Athenians, lay now encamped in the isthmus near unto Olynthus and had the market kept for them without the city.

And the leading of the foot the confederates had assigned to Aristeus, and of the horse to Perdiccas; for he fell off again presently from the Athenians and, having left Iolaus governor in his place, took part with the Potidaeans.
