History of the Peloponnesian War

About the same time in this summer, the Lacedaemonians invaded Argos with their allies, and laid waste most of the country. The Athenians went with thirty ships to the relief of the Argives, thus breaking their treaty with the Lacedaemonians in the most overt manner.

Up to this time incursions from Pylos, descents on the coasts of the rest of Peloponnese, instead of on the Laconian, had been the extent of their cooperation with the Argives and Mantineans; and although the Argives had often begged them to land, if only for a moment, with their heavy infantry in Laconia, lay waste ever so little of it with them, and depart, they had always refused to do so. Now, however, under the command of Pythodorus, Laespodius, and Demaratus, they landed at Epidaurus, Limera, Prasiae, and other places, and plundered the country; and thus furnished the Lacedaemonians with a better pretext for hostilities against Athens.

After the Athenians had retired from Argos with their fleet, and the Lacedaemonians also, the Argives made an incursion into the Phliasid, and returned home after ravaging their land and killing some of the inhabitants.
