Passage 3.9.10
ἐπηγάγοντο οὖν οἱ Λοκροὶ συμμάχους Θηβαίους καὶ τὴν Φωκίδα ἐπόρθησαν· ἐς δὲ τὴν Λακεδαίμονα ἐλθόντες οἱ Φωκεῖς τοῖς Θηβαίοις ἐπέκειντο καὶ ἐδίδασκον οἷα ἐπεπόνθεσαν ὑπʼ αὐτῶν. Λακεδαιμονίοις δὲ πόλεμον πρὸς Θηβαίους ἔδοξεν ἄρασθαι· ἐποιοῦντο δὲ ἐς αὐτοὺς καὶ ἄλλα ἐγκλήματα καὶ τὴν ἐν Αὐλίδι αὐτῶν ὕβριν ἐς τὴν Ἀγησιλάου θυσίαν.
Therefore the Locrians brought in the Thebans as allies and devastated Phocis. The Phocians, going to Sparta, accused the Thebans vehemently and recounted the wrongs they had suffered at their hands. Consequently, the Spartans decided to declare war upon the Thebans, charging them also with other grievances, notably the outrage committed at Aulis during the sacrifice performed by Agesilaus.
