History of the Peloponnesian War

But touching Alcibiades, the Athenians took it extreme ill through the instigation of his enemies, the same that had opposed him before he went. And seeing it was certain, as they thought, for the Mercuries, the other crime also concerning the mysteries, whereof he had been accused, seemed a great deal the more to have been committed by him upon the same reason and conspiracy against the people.

For it fell out withal, whilst the city was in a tumult about this, that an army of the Lacedaemonians was come as far as the isthmus upon some design against the Boeotians. These therefore they thought were come thither not against the Boeotians, but by appointment of him, and that if they had not first apprehended the persons appeached, the city had been betrayed. And one night they watched all night long in their arms in the temple of Theseus within the city.

And the friends of Alcibiades in Argos were at the same time suspected of a purpose to set upon the people there; whereupon the Athenians also delivered unto the Argive people those hostages which they held of theirs in the islands to be slain.

And there were presumptions against Alcibiades on all sides. Insomuch, as purposing by law to put him to death, they sent, as I have said, the galley called Salaminia into Sicily both for him and the rest with him that had been accused;

but gave command to those that went not to apprehend him, but to bid him follow them to make his purgation, because they had a care not to give occasion of stir either amongst their own or their enemy's soldiers, but especially because they desired that the Mantineans and the Argives, who they thought followed the war by his persuasion, might not depart from the army.
