History of the Peloponnesian War

But two individuals of the Argives, Thrasyllus, one of the five generals, and Alciphron, the proxenus of the Lacedaemonians, when the armies were now on the very point of engaging, went to Agis, and in a conference urged him not to bring on a battle; since the Argives were prepared to give and accept fair and equal arbitration for whatever complaints the Lacedaemonians had against them, and to make a treaty and live in peace for the future.

Those of the Argives who made these statements did so on their own authority, and not by order of the people; and Agis on his own discretion received their proposals; and without consulting, any more than they had, with the majority, but only communicating them to one of the officers who joined the expedition, granted a truce for four months, during which they were to fulfil their agreement. And so he immediately led back the army, without explaining the matter to any of the other confederates.
