History of the Peloponnesian War

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.

So he and the rest accused with him in his own galley, in company of the Salaminia, left Sicily and set sail for Athens. But being at Thurii they followed no further, but left the galley and were no more to be found, fearing indeed to appear to the accusation.
