§10.49.1γενομένης δὲ τῆς προσαγγελίας διότι συμβαίνει τὸν μὲν Εὐθύδημον μετὰ τῆς δυνάμεως εἶναι περὶ Ταπουρίαν, μυρίους δʼ ἱππεῖς προκαθίζεσθαι φυλάττοντας τὰς περὶ τὸν Ἄριον ποταμὸν διαβάσεις, ἔκρινε τὴν πολιορκίαν ἀπογνοὺς ἔχεσθαι τῶν προκειμένων.
When the report arrived that Euthydemus was near Tapuria with his forces, and that ten thousand cavalry were posted in advance to guard the crossings of the river Arius, he gave up the siege and decided to apply himself to the plans before him.
§10.49.2ἀπέχοντος δὲ τοῦ ποταμοῦ τριῶν ἡμερῶν ὁδόν, ἐπὶ μὲν ἡμέρας δύο σύμμετρον ἐποιήσατο τὴν πορείαν, τῇ δὲ τρίτῃ μετὰ τὸ δειπνῆσαι τοῖς ἄλλοις ἅμα τῷ φωτὶ ποιεῖσθαι παρήγγειλε τὴν ἀναζυγήν, αὐτὸς δʼ ἀναλαβὼν τοὺς ἱππέας καὶ τοὺς εὐζώνους, §10.49.3ἅμα δὲ πελταστὰς μυρίους, προῆγε νυκτός, πορείᾳ χρώμενος ἐνεργῷ.
Since the river was three days' journey away, he marched at a moderate pace for two days; on the third day, after the others had taken their dinner, he ordered them to break camp at daybreak, while he himself took the cavalry and the light-armed troops, along with ten thousand peltasts, and advanced by night, making a rapid march.
§10.49.4τοὺς γὰρ ἱππεῖς ἐπυνθάνετο τῶν ὑπεναντίων τὰς μὲν ἡμέρας ἐφεδρεύειν παρὰ τὸ χεῖλος τοῦ ποταμοῦ, τὰς δὲ νύκτας ὑποχωρεῖν πρός τινα πόλιν οὐκ ἔλαττον εἴκοσι σταδίων διέχουσαν.
For he had learned that the enemy's cavalry kept watch by the bank of the river during the day, but by night retired to a city at least twenty stades distant.
διανύσας δὲ νύκτωρ τὴν καταλειπομένην ὁδόν, §10.49.5ἅτε τῶν πεδίων ἱππασίμων ὑπαρχόντων, ἔφθασε περαιώσας τὸν ποταμὸν ἅμα τῷ φωτὶ τὸ πλεῖστον μέρος τῆς μεθʼ ἑαυτοῦ δυνάμεως.
Having accomplished the rest of the journey during the night, as the plains were suitable for riding, he succeeded in getting the greater part of his force across the river at daybreak before the enemy could prevent it.
§10.49.6οἱ δὲ τῶν Βακτριανῶν ἱππεῖς, σημηνάντων αὐτοῖς τῶν σκοπῶν τὸ γεγονός, ἐξεβοήθουν, καὶ κατὰ πορείαν συνέμισγον τοῖς ὑπεναντίοις.
When the scouts reported to the Bactrian cavalry what had happened, they sallied out and clashed with the enemy while on the march.
§10.49.7ὁ δὲ βασιλεύς, θεωρῶν ὅτι δεῖ δέξασθαι τὴν πρώτην ἐπιφορὰν τῶν πολεμίων, παρακαλέσας τοὺς περὶ αὐτὸν εἰθισμένους κινδυνεύειν τῶν ἱππέων δισχιλίους, τοῖς μὲν ἄλλοις παρήγγειλε κατὰ σημαίας καὶ κατʼ οὐλαμοὺς αὐτοῦ παρεμβαλεῖν καὶ λαμβάνειν ἑκάστους τὰς εἰθισμένας τάξεις,
The king, seeing that he must receive the first onset of the enemy, encouraged two thousand of his cavalry who were accustomed to fight around him, and ordered the rest to form up on the spot by companies and squadrons, each taking their usual positions.
§10.49.8αὐτὸς δὲ μετὰ τῶν προειρημένων ἱππέων ἀπαντήσας συνέβαλε τοῖς πρώτοις ἐπιφερομένοις τῶν Βάκτρων.
He himself, advancing with the aforesaid cavalry, charged the first of the Bactrians who came on.
§10.49.9δοκεῖ δὲ κατὰ τοῦτον τὸν κίνδυνον Ἀντίοχος ἀγωνίσασθαι διαπρεπέστατα τῶν μεθʼ αὑτοῦ.
In this encounter, Antiochus is thought to have fought more brilliantly than any of his companions.
§10.49.10πολλοὶ μὲν οὖν ἀμφοτέρων διεφθάρησαν, ἐπεκράτησαν δὲ τῆς πρώτης ἱππαρχίας οἱ μετὰ τοῦ βασιλέως· τῆς δὲ δευτέρας καὶ τρίτης ἐπιφερομένης ἐπιέζοντο καὶ κακῶς ἀπήλλαττον.
Many fell on both sides, but those with the king defeated the first squadron; however, when the second and third charged, they were hard pressed and suffered severely.
§10.49.11κατὰ δὲ τὸν καιρὸν τοῦτον, τῶν πλείστων ἱππέων ἐκτεταγμένων ἤδη, Παναίτωλος ἐπαγαγεῖν παραγγείλας τὸν μὲν βασιλέα καὶ τοὺς μετʼ αὐτοῦ κινδυνεύοντας ἐδέξατο, τοὺς δὲ τῶν Βακτριανῶν ἐπιφερομένους ἀτάκτως ἐκ μεταβολῆς προτροπάδην ἠνάγκασε φυγεῖν.
At this critical moment, as most of his cavalry were already drawn up, Panaitolos ordered an advance, received the king and those who were in danger with him, and forced the Bactrians, who were attacking in disorder, to turn and flee in headlong flight.
§10.49.12ἐκεῖνοι μὲν οὖν, τῶν περὶ τὸν Παναίτωλον αὐτοῖς ἐπικειμένων, οὐ πρότερον ἔστησαν ἕως οὗ συνέμιξαν τοῖς περὶ τὸν Εὐθύδημον, τοὺς πλείστους ἀπολωλεκότες αὑτῶν· οἱ δὲ τοῦ βασιλέως ἱππεῖς, §10.49.13πολλοὺς μὲν φονεύσαντες, πολλοὺς δὲ ζωγρίᾳ λαβόντες, ἀνεχώρουν.
The latter, hard pressed by Panaitolos and his men, did not halt until they joined Euthydemus, having lost most of their number; while the king's cavalry, having slain many and taken many alive, retired.
καὶ τότε μὲν αὐτοῦ παρὰ τὸν ποταμὸν ηὐλίσθησαν·
For that night they encamped on the spot by the river.
§10.49.14ἐν δὲ τούτῳ τῷ κινδύνῳ τὸν μὲν ἵππον συμβαίνει ἀποθανεῖν τραυματισθέντα, αὐτὸν δὲ πληγέντα διὰ τοῦ στόματος ἀποβαλεῖν τινας· τῶν ὀδόντων, καθόλου δὲ φήμην ἐπʼ ἀνδρείᾳ περιποιήσασθαι τότε μάλιστα.
In this action, it happened that the king's horse was wounded and died, and he himself was struck in the mouth and lost several of his teeth, but on the whole he acquired a very high reputation for courage on this occasion.
§10.49.15γενομένης δὲ τῆς μάχης ταύτης ὁ μὲν Εὐθύδημος καταπλαγεὶς ἀνεχώρησε μετὰ τῆς δυνάμεως εἰς πόλιν Ζαριάσπαν τῆς Βακτριανῆς.
After this battle, Euthydemus, struck with terror, retreated with his army to Zariaspa, a city of Bactria.
