§6.115.1ἑπτὰ μὲν δὴ τῶν νεῶν ἐπεκράτησαν τρόπῳ τοιῷδε Ἀθηναῖοι· τῇσι δὲ λοιπῇσι οἱ βάρβαροι ἐξανακρουσάμενοι, καὶ ἀναλαβόντες ἐκ τῆς νήσου ἐν τῇ ἔλιπον τὰ ἐξ Ἐρετρίης ἀνδράποδα, περιέπλεον Σούνιον βουλόμενοι φθῆναι τοὺς Ἀθηναίους ἀπικόμενοι ἐς τὸ ἄστυ.
Now, in this manner the Athenians became masters of seven of the ships; but with the remaining ones the barbarians pushed off from land, and having taken up from the island where they had left them the captives from Eretria, they sailed round Sunium, wishing to forestall the Athenians by arriving at the city.
αἰτίην δὲ ἔσχε ἐν Ἀθηναίοισι ἐξ Ἀλκμεωνιδέων μηχανῆς αὐτοὺς ταῦτα ἐπινοηθῆναι· τούτους γὰρ συνθεμένους τοῖσι Πέρσῃσι ἀναδέξαι ἀσπίδα ἐοῦσι ἤδη ἐν τῇσι νηυσί.
And a charge was held among the Athenians that they had devised this by a plot of the Alcmeonidae; for these, it was said, having made an agreement with the Persians, held up a shield as a signal to them when they were already in their ships.
