And the Lacedaemonians ordered the state of Achaia after their own form, which before was otherwise. [2] But the Argives, after they had by little and little assembled themselves and recovered heart, taking the time when the Lacedaemonians were celebrating their exercises of the naked youth, assaulted the few; and in a battle fought within the city, the commons had the victory; and some they slew, others they drave into exile. [3] The Lacedaemonians, though those of their faction in Argos sent for them, went not a long time after; yet at last they adjourned the exercises and came forth with intention of giving them aid. But hearing by the way at Tegea that the few were overcome, they could not be entreated by such as had escaped thence to go on, but returning, went on with the celebration of their exercises. [4] 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; [5] 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. [6] 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 sto<*> from Athens. So this summer ended.
