History of the Peloponnesian War

The same summer Alcibiades, son of Clinias, now one of the generals at Athens, in concert with the Argives and the allies, went into Peloponnese with a few Athenian heavy infantry and archers, and some of the allies in those parts whom he took up as he passed, and with this army marched here and there through Peloponnese, and settled various matters connected with the alliance, and among other things induced the Patrians to carry their walls down to the sea, intending himself also to build a fort near the Achaean Rhium. However, the Corinthians and Sicyonians, and all others who would have suffered by its being built, came up and hindered him.

The same summer war broke out between the Epidaurians and Argives. The pretext was that the Epidaurians did not send an offering for their pasture-land to Apollo Pythaeus, as they were bound to do, the Argives having the chief management of the temple; but, apart from this pretext, Alcibiades and the Argives were determined, if possible, to gain possession of Epidaurus, and thus to insure the neutrality of Corinth and give the Athenians a shorter passage for their reinforcement from Aegina than if they had to sail round Scyllaeum. The Argives accordingly prepared to invade Epidaurus by themselves, to exact the offering.

About the same time the Lacedaemonians marched out with all their people to Leuctra upon their frontier, opposite to Mount Lycaeum, under the command of Agis, son of Archidamus, without any one knowing their destination, not even the cities that sent the contingents.

The sacrifices, however, for crossing the frontier not proving propitious, the Lacedaemonians returned home themselves, and sent word to the allies to be ready to march after the month ensuing, which happened to be the month of Carneus, a holy time for the Dorians.

Upon the retreat of the Lacedaemonians the Argives marched out on the last day but three of the month before Carneus, and keeping this as the day during the whole time that they were out, invaded and plundered Epidaurus.
