§8.15.1τρίτῃ δὲ ἡμέρῃ δεινόν τι ποιησάμενοι οἱ στρατηγοὶ τῶν βαρβάρων νέας οὕτω σφι ὀλίγας λυμαίνεσθαι, καὶ τὸ ἀπὸ Ξέρξεω δειμαίνοντες, οὐκ ἀνέμειναν ἔτι τοὺς Ἕλληνας μάχης ἄρξαι, ἀλλὰ παρακελευσάμενοι κατὰ μέσον ἡμέρης ἀνῆγον τὰς νέας.
On the third day, the generals of the barbarians, deeming it a shameful thing that so few ships should inflict damage upon them, and fearing the consequences from Xerxes, did not wait any longer for the Greeks to begin the battle, but after encouraging one another, they put their ships to sea about midday.
συνέπιπτε δὲ ὥστε τὰς αὐτὰς ἡμέρας τάς τε ναυμαχίας γίνεσθαι ταύτας καὶ τὰς πεζομαχίας τὰς ἐν Θερμοπύλῃσι.
And it so happened that these sea-fights and the land-battles at Thermopylae took place on the very same days.
§8.15.2ἦν δὲ πᾶς ὁ ἀγὼν τοῖσι κατὰ θάλασσαν περὶ τοῦ Εὐρίπου, ὥσπερ τοῖσι ἀμφὶ Λεωνίδην τὴν ἐσβολὴν φυλάσσειν.
The whole struggle for those at sea was for the Euripus, just as it was for Leonidas and his men to guard the pass.
οἳ μὲν δὴ παρεκελεύοντο ὅκως μὴ παρήσουσι ἐς τὴν Ἑλλάδα τοὺς βαρβάρους, οἳ δʼ ὅκως τὸ Ἑλληνικὸν στράτευμα διαφθείραντες τοῦ πόρου κρατήσουσι.
The former, indeed, exhorted one another that they should not let the barbarians pass into Greece, while the latter did so to destroy the Greek force and gain control of the passage.
ὡς δὲ ταξάμενοι οἱ Ξέρξεω ἐπέπλεον, οἱ Ἕλληνες ἀτρέμας εἶχον πρὸς τῷ Ἀρτεμισίῳ.
When those of Xerxes sailed against them in order of battle, the Greeks remained quiet at Artemisium.
οἱ δὲ βάρβαροι μηνοειδὲς ποιήσαντες τῶν νεῶν ἐκυκλοῦντο, ὡς περιλάβοιεν αὐτούς.
But the barbarians, forming a crescent with their ships, began to encircle them, so that they might trap them.
