4.30.4

καὶ οὗτοι ἐπὶ τοὺς ἀποχωροῦντας τῶν βαρβάρων τραπόμενοι ἀπὸ ξυνθήματος, πολλοὺς μὲν αὐτῶν ἐν τῇ φυγῇ ἀπέκτειναν, οἱ δὲ καὶ πεφοβημένως ἀποχωροῦντες κατὰ τῶν κρημνῶν ῥίψαντες σφᾶς ἀπέθανον. εἴχετό τε Ἀλεξάνδρῳ ἡ πέτρα ἡ τῷ Ἡρακλεῖ ἄπορος γενομένη καὶ ἔθυεν ἐπʼ αὐτῇ Ἀλέξανδρος καὶ κατεσκεύασε φρούριον, παραδοὺς Σισικόττῳ ἐπιμελεῖσθαι τῆς φρουρᾶς, ὃς ἐξ Ἰνδῶν μὲν πάλαι ηὐτομολήκει ἐς Βάκτρα παρὰ Βῆσσον, Ἀλεξάνδρου δὲ κατασχόντος τὴν χώραν τὴν Βακτρίαν ξυνεστράτευέ τε αὐτῷ καὶ πιστὸς ἐς τὰ μάλιστα ἐφαίνετο.

He was himself the first to reach the top, the Macedonians ascending after him pulling one another up, some at one place and some at another. Then at a preconcerted signal they turned upon the retreating barbarians and slew many of them in the flight, besides so terrifying some others that in retreating they flung themselves down the precipices, and were in consequence dashed to death. Alexander thus became master of the rock which had baffled Herakles himself. He sacrificed upon it and built a fort, giving the command of its garrison to Sisikottos, who long before had in Baktra deserted from the Indians to Bessos, but after Alexander had conquered the Baktrian land served in his army, and showed himself a man worthy of all confidence.
