History of the Peloponnesian War

He, however, thought that the city was not in a settled state, and that the people would not so immediately give up their ancient liberty, nor remain quiet, if they should see a large force of Lacedaemonians; and not being quite sure at present that they were no longer in a disturbed condition, he made no conciliatory answer to those who had come from the Four Hundred, but sent for a large additional force from the Peloponnese, and not long after went down himself with the garrison from Decelea, in conjunction with the troops which had joined him, to the very walls of Athens; hoping that either the people there, being thrown into disorder, would submit on his own terms, or that in consequence of the confusion which would probably be created both within and without, he could not fail to carry the long walls on the first assault, owing to the absence of troops along them for their defence.

But when he approached near to the city, and the Athenians made not the slightest stir within, while they sent out their cavalry, with a division of their heavy-armed, light-armed, and archers, and shot down some of the enemy in consequence of their near advance, and got possession of some arms and dead bodies, then indeed, finding this to be the case, he led his army back again.

He and his own troops still remained in their former position at Decelea, but the newly arrived forces he sent home, after they had staid in the country some few days. After this, the Four Hundred sent an embassy to Agis nevertheless; and when he now received them more favourably, and advised them to that effect, they sent envoys to Lacedaemon also to negotiate a treaty, being desirous of peace.
