History of the Peloponnesian War

Accordingly, while the Athenians were at that time ravaging their seaboard, they generally kept quiet when any descent was made upon any particular garrison, each thinking itself inferior in number and there being such depression. One garrison, however, which offered resistance in the region of Cotyrta and Aphrodisia, frightened the scattered crowd of light-armed troops by a charge, but when it encountered hoplites retreated again, a few of their men being killed and some of their arms taken; and the Athenians, after setting up a trophy, sailed back to Cythera.

From there they sailed to Epidaurus Limera, and after ravaging some part of the land came to Thyrea, which belongs to the district called Cynuria, on the border between the Argive and Laconian territories. This district the Lacedaemonians who occupied it had given to the expelled Aeginetans to dwell in, on account of the kind services shown themselves at the time of the earthquake and the uprising of the Helots, and because they had always sided with their policy, in spite of being subject to the Athenians.

While, then, the Athenians were still sailing up, the Aeginetans left the fort by the sea which they happened to be building and withdrew to the upper town, where they dwelt, at a distance of about ten stadia from the sea.

Now a detachment of the Lacedaemonian troops which were distributed in garrisons about the country was assisting the Aeginetans to build this fort. But they refused to enter the fort with them, as they requested, since it seemed to them dangerous to be cooped up in it; but retreating to high ground they kept quiet, thinking themselves no match for the enemy.
