The next day the thirty Athenian vessels put out to sea, accompanied by all the Corcyraean ships that were seaworthy, and sailed to the harbor at Sybota, where the Corinthians lay, to see if they would engage. The Corinthians put out from the land, and formed a line in the open sea, but beyond this made no further movement, having no intention of assuming the offensive. For they saw reinforcements arrived fresh from Athens, and themselves confronted by numerous difficulties, such as the necessity of guarding the prisoners whom they had on board, and the want of all means of refitting their ships in a desert place. What they were thinking more about was how their voyage home was to be effected; they feared that the Athenians might consider that the treaty was dissolved by the collision which had occurred, and forbid their departure.
