The Epidaurians were reinforced about the end of September by a detachment of three hundred Lacedæmonian hoplites under Agesippidas, sent by sea without the knowledge of the Athenians. Of this, the Argeians preferred loud complaints at Athens; and they had good reason to condemn the negligence of the Athenians as allies, for not having kept better naval watch at their neighboring station of Ægina, and for having allowed this enemy to enter the harbor of Epidaurus. But they took another ground of complaint, somewhat remarkable. In the alliance between Athens, Argos, Elis, and Mantineia, it had been stipulated that neither of the four should suffer the passage of troops through its territory, without the joint consent of all. Now the sea was accounted a part of the territory of Athens: so that the Athenians had violated this article of the treaty by permitting the Lacedæmonians to send troops by sea to Epidaurus. And the Argeians now required Athens, in compensation for this wrong, to carry back the Messenians and Helots from Kephallenia to Pylos, and allow them to ravage Laconia. The Athenians, under the persuasion of Alkibiadês, complied with their requisition; inscribing, at the foot of the pillar on which their alliance with Sparta stood recorded, that the Lacedæmonians had not observed their oaths. Nevertheless, they still abstained from formally throwing up their treaty with Lacedæmon, or breaking it in any other way.[101] The relations between Athens and Sparta thus remained in name, peace and alliance, so far as concerns direct operations against each other’s territory; in reality, hostile action as well as hostile manœuvring, against each other, as allies respectively of third parties. [101] Thucyd. v, 56. The Argeians, after having prolonged their incursions on the Epidaurian territory throughout all the autumn, made in the winter an unavailing attempt to take the town itself by storm. Though there was no considerable action, but merely a succession of desultory attacks, in some of which the Epidaurians even had the advantage, yet they still suffered serious hardship, and pressed their case forcibly on the sympathy of Sparta. Thus importuned, and mortified as well as alarmed by the increasing defection or coldness which they now experienced throughout Peloponnesus, the Lacedæmonians determined during the course of the ensuing summer to put forth their strength vigorously, and win back their lost ground.[102] [102] Thucyd. v, 37.
