History of the Peloponnesian War

After this the Argives marched into Phlius and plundered it for harboring their exiles, most of whom had settled there, and so returned home.

The same winter the Athenians blockaded Macedonia, on the score of the league entered into by Perdiccas with the Argives and Lacedaemonians, and also of his breach of his engagements on the occasion of the expedition prepared by Athens against the Chalcidians in the direction of Thrace and against Amphipolis, under the command of Nicias, son of Niceratus which had to be broken up mainly because of his desertion. He was therefore proclaimed an enemy. And thus the winter ended, and the fifteenth year of the war ended with it.
