§7.175.1οἱ δὲ Ἕλληνες ἐπείτε ἀπίκατο ἐς τὸν Ἰσθμόν, ἐβουλεύοντο πρὸς τὰ λεχθέντα ἐξ Ἀλεξάνδρου τῇ τε στήσονται τὸν πόλεμον καὶ ἐν οἵοισι χώροισι.
When the Greeks had arrived at the Isthmus, they deliberated, in view of the message delivered from Alexander, where and in what kind of places they should establish the war.
ἡ νικῶσα δὲ γνώμη ἐγίνετο τὴν ἐν Θερμοπύλῃσι ἐσβολὴν φυλάξαι· στεινοτέρη γὰρ ἐφαίνετο ἐοῦσα τῆς ἐς Θεσσαλίην καὶ ἅμα ἀγχοτέρη τῆς ἑωυτῶν·
The prevailing opinion was to guard the pass at Thermopylae; for it appeared to be narrower than the pass into Thessaly, and at the same time closer to their own territory.
§7.175.2τὴν δὲ ἀτραπόν, διʼ ἣν ἥλωσαν οἱ ἁλόντες Ἑλλήνων ἐν Θερμοπύλῃσι, οὐδὲ ᾔδεσαν ἐοῦσαν πρότερον ἤ περ ἀπικόμενοι ἐς Θερμοπύλας ἐπύθοντο Τρηχινίων.
As for the path through which those of the Greeks who were captured at Thermopylae were undone, they did not even know of its existence beforehand, until, having arrived at Thermopylae, they learned of it from the Trachinians.
ταύτην ὦν ἐβουλεύσαντο φυλάσσοντες τὴν ἐσβολὴν μὴ παριέναι ἐς τὴν Ἑλλάδα τὸν βάρβαρον, τὸν δὲ ναυτικὸν στρατὸν πλέειν γῆς τῆς Ἱστιαιώτιδος ἐπὶ Ἀρτεμίσιον.
Therefore, they resolved to guard this pass and not permit the barbarian to enter Greece, and that the naval force should sail to Artemisium in the territory of Histiaeotis.
ταῦτα γὰρ ἀγχοῦ τε ἀλλήλων ἐστὶ ὥστε πυνθάνεσθαι τὰ κατὰ ἑκατέρους ἐόντα, οἵ τε χῶροι οὕτω ἔχουσι.
For these places are close to each other, so that they could learn what was happening to each other, and the positions of the places are such.
