History of the Peloponnesian War

After the withdrawal of the Argives from the alliance, the Mantineans also, although at first opposed to this course, afterwards, finding themselves unable to hold out without the Argives, likewise made an agreement with the Lacedaemonians and relinquished their sovereignty over the cities.[*](ie. over the Parrhasians and others in Arcadia; cf. ch. xxix. 1; xxxiii. 1; xii. 1.)

And now the Lacedaemonians and Argives, each a thousand strong, made a joint expedition, the Lacedaemonians first going alone and setting up a more oligarchical form of government in Sicyon, afterwards both together putting down the democracy at Argos and establishing an oligarchy favourable to the Lacedaemonians. These things occurred when the winter was closing and spring was now near at hand; and so ended the fourteenth year of the war.
