History of the Peloponnesian War

Against this city marched Brasidas with his army, dislodging from Arnae in Chalcidea. Being about twilight come as far as Aulon and Bromiscus, where the lake Bolbe entereth into the sea, he caused his army to sup, and then marched forward by night.

The weather was foul, and a little it snowed, which also made him to march the rather, as desiring that none of Amphipolis, but only the traitors, should be aware of his coming.

For there were both Argilians that dwelt in the same city (now Argilus is a colony of the Andrians), and others, that contrived this, induced thereunto some by Perdiccas and some by the Chalcideans.
