Passage 8.6.2
Λακεδαιμονίοις δὲ ἀνάγκῃ πλέον καὶ οὐ μετʼ εὐνοίας ἐπί τε Ἀθηναίους συνεστρατεύσαντο καὶ ἐς τὴν Ἀσίαν μετὰ Ἀγησιλάου διέβησαν, καὶ δὴ καὶ ἐς Λεῦκτρα αὐτοῖς τὰ Βοιωτικὰ ἠκολούθησαν. τὸ δὲ ὕποπτον τὸ ἐς τοὺς Λακεδαιμονίους ἀλλαχοῦ τε ἐπεδείξαντο καὶ μετὰ τὸ ἀτύχημα Λακεδαιμονίων τὸ ἐν Λεύκτροις παρὰ Θηβαίους αὐτίκα ἀπʼ αὐτῶν μετέστησαν. Φιλίππῳ δὲ καὶ Μακεδόσιν ἐν Χαιρωνείᾳ καὶ ὕστερον ἐν Θεσσαλίᾳ πρὸς Ἀντίπατρον οὐκ ἐμαχέσαντο μετὰ Ἑλλήνων, οὐ μὴν οὐδὲ τοῖς Ἕλλησιν ἐναντία ἐτάξαντο.
The Spartans compelled them by necessity rather than willing allegiance, and thus they fought alongside them against Athens and crossed into Asia with Agesilaus; indeed, they followed the Spartans even to their battle with the Boeotians at Leuctra. Nevertheless, their mistrust toward the Spartans was made evident elsewhere as well, and immediately after Sparta’s defeat by the Thebans at Leuctra they promptly revolted from them. At Chaeronea against Philip and the Macedonians, and later in Thessaly against Antipater, they refused to fight alongside the Greeks, yet neither did they take up arms openly against them.
