and now took the unusual step of raising four hundred horse and a force of archers, and became more timid than ever in military matters, finding themselves involved in a maritime struggle, which their organisation had never contemplated, and that against Athenians, with whom an enterprise unattempted was always looked upon as a success sacrificed.
Besides this, their late numerous reverses of fortune, coming close one upon another without any reason, had thoroughly unnerved them, and they were always afraid of a second disaster like that on the island,
and thus scarcely dared to take the field, but fancied that they could not stir without a blunder, for being new to the experience of adversity they had lost all confidence in themselves.
Accordingly they now allowed the Athenians to ravage their seaboard, without making any movement, the garrisons in whose neighbourhood the descents were made always thinking their numbers insufficient, and sharing the general feeling. A single garrison which ventured to resist, near Cotyrta and Aphrodisia, struck terror by its charge into the scattered mob of light troops, but retreated, upon being received by the heavy infantry, with the loss of a few men and some arms, for which the Athenians set up a trophy, and then sailed off to Cythera.
From thence they sailed round to the Limeran Epidaurus, ravaged part of the country, and so came to Thyrea in the Cynurian territory, upon the Argive and Laconian border. This district had been given by its Lacedaemonian owners to the expelled Aeginetans to inhabit, in return for their good offices at the time of the earthquake and the rising of the Helots; and also because, although subjects of Athens, they had always sided with Lacedaemon.
