History of the Peloponnesian War

The Syracusians, having fought in this manner with the utmost of their strength, in the end gat the victory; and the Athenians, between the [two] ships, escaped into their harbour.

The Syracusian galleys chased them as far as to those ships; but the dolphins hanging from the masts over the entrance of the harbour forbade them to follow any further.

Yet there were two galleys, which upon a jollity after victory approached them, but both were lost, of which one with her men and all was taken.

The Syracusians, after they had sunk seven galleys of the Athenians and torn many more, and of the men had taken some alive and killed others, retired, and for both the battles erected trophies, and had already an assured hope of being far superior by sea, and also made account to subdue the army by land. And they prepared to assault them again in both kinds.
