History of the Peloponnesian War

But afterwards, when there came ambassadors unto them, both from the Argives in the city, and from them that were driven out, there being present also their confederates, and much alleged on either side, they concluded at last that those in the city had done the wrong and decreed to go against Argos with their army;

but many delays passed, and much time was spent between. In the meantime the common people of Argos, fearing the Lacedaemonians and regaining the league with Athens, as conceiving the same would turn to their very great advantage, raised long walls from their city down to the sea-shore, to the end that if they were shut up by land, they might yet with the help of the Athenians bring things necessary into the city by sea.

And with this their building some other cities of Peloponnesus were also acquainted. And the Argives universally, themselves and wives and servants, wrought at the wall, and had workmen and hewers of stone from Athens. So this summer ended.

The next winter the Lacedaemonians, understanding that they were fortifying, came to Argos with their army, they and their confederates all but the Corinthians; and some practice they had beside within the city itself of Argos. The army was commanded by Agis, the son of Archidamus, king of the Lacedaemonians.
