Passage 9.15.3
ἐν ὅσῳ δὲ ἀπῆν ὁ Ἐπαμινώνδας, Ὀρχομενίους Θηβαῖοι ποιοῦσιν ἀναστάτους ἐκ τῆς χώρας· συμφορὰν δὲ τὴν ἀνάστασιν τὴν Ὀρχομενίων ἐνόμιζεν ὁ Ἐπαμινώνδας καὶ οὔ ποτʼ ἂν ἐξεργασθῆναι τόλμημα τοιοῦτον αὐτοῦ γε παρόντος ἔφασκεν ὑπὸ Θηβαίων.
But while Epaminondas was absent, the Thebans drove out the Orchomenians completely from their land. Epaminondas considered the expulsion of the Orchomenians a misfortune, and declared that such a deed would never have been committed by the Thebans had he himself been present.
