In-the middle of the following summer, the Lacedaemonians, seeing that their Epidaurian allies were in great1
distress, and that several cities of Peloponnesus had seceded from them, while others were disaffected, and knowing that if they did not quickly2
take measures of precaution the evil would spread, made war on Argos with their whole forces, including the Helots, under the command of Agis the son of Archidamus, the Lacedaemonian king.
The Tegeans and the other Arcadian allies of the Lacedaemonians took part in the expedition. The rest of their allies, both from within and without the Peloponnesus, mustered at Phlius. Among the other contingents there came from Boeotia five thousand heavy-armed, and as many light-armed, five hundred cavalry, and attached to each horseman a foot-soldier; and from Corinth two thousand heavy-armed, while the Phliasians joined with their whole force, because the army was to assemble in their country.
