Passage 10.17.6
Ἰλίου δὲ ἁλισκομένης ἄλλοι τε ἐκφεύγουσι τῶν Τρώων καὶ οἱ ἀποσωθέντες μετὰ Αἰνείου· τούτων μοῖρα ἀπενεχθεῖσα ὑπὸ ἀνέμων ἐς Σαρδὼ ἀνεμίχθησαν τοῖς προενοικοῦσιν Ἕλλησι. καταστῆναι δὲ ἐς μάχην τῷ Ἑλληνικῷ καὶ τοῖς Τρωσὶν ἐκώλυσε τοὺς βαρβάρους· παρασκευῇ τε γὰρ ἴσοι τῇ ἁπάσῃ τὰ ἐς πόλεμον ἦσαν καὶ ὁ Θόρσος ποταμὸς διὰ μέσου σφίσι ῥέων τῆς χώρας ἐπʼ ἴσης καὶ ἀμφοτέροις διαβαίνειν παρεῖχε δέος.
When Ilium was captured, among other Trojans who managed to escape were those who fled with Aeneas. Some of these, having been carried by winds to Sardinia, mixed with the Greeks who previously inhabited the island. A confrontation between the Greeks and these Trojans was prevented by the barbarians: for each side was equal in their full military preparedness, and the river Thorsus, flowing through the country between them, made both equally fearful of crossing.
