History of the Peloponnesian War

The Athenians, by the mouth of Alcibiades their ambassador there present, told the Argives and the allies that they had no right to make a truce at all without the consent of their fellow-confederates, and now that the Athenians had arrived so opportunely the war ought to be resumed.

These arguments proving successful with the allies, they immediately marched upon Orchomenos, all except the Argives, who, although they had consented like the rest, stayed behind at first, but eventually joined the others.
