History of the Peloponnesian War

The following winter, when the Lacedaemonians were aware of their building the walls, they marched against Argos, both themselves and their allies, excepting the Corinthians; communication being also held with them from Argos itself. The leader of the army was Agis, son of Archidamus, king of the Lacedaemonians.

With regard, then, to the advantages which they thought they had secured in the city itself, nothing more came of them; but the walls that were being built, they took and demolished. And having taken Hysiae, a town in the Argive territory, and put to the sword all the free-men they got into their hands, they returned, and dispersed to their respective cities.
