History of the Peloponnesian War

For about the same time as the campaign in Lyncus, the Athenians sailed upon the expedition which we left them preparing against Mende and Scione, with fifty ships, ten of which were Chians, one thousand Athenian heavy infantry and six hundred archers, one hundred Thracian mercenaries and some targeteers drawn from their allies in the neighbourhood, under the command of Nicias, son of Niceratus, and Nicostratus, son of Diitrephes.

Weighing from Potidaea, the fleet came to land opposite the temple of Poseidon, and proceeded against Mende; the men of which town, reinforced by three hundred Scionaeans, with their Peloponnesians auxiliaries, seven hundred heavy infantry in all, under Polydamidas, they found encamped upon a strong hill outside the city.
