Passage 3.9.6
γενομένης δὲ πρὸς Τισσαφέρνην σατράπην τῶν περὶ Ἰωνίαν μάχης ἐν Ἕρμου πεδίῳ τήν τε ἵππον τῶν Περσῶν ἐνίκησεν ὁ Ἀγησίλαος καὶ τὸ πεζὸν τότε πλεῖστον ἀθροισθὲν μετά γε τὸν Ξέρξου καὶ πρότερον ἔτι ἐπὶ Σκύθας Δαρείου καὶ ἐπὶ Ἀθήνας στρατόν. Λακεδαιμόνιοι δὲ ἀγασθέντες τὸ ἐς τὰ πράγματα τοῦ Ἀγησιλάου πρόθυμον διδόασιν ἄρχοντα εἶναι καὶ τῶν νεῶν αὐτῷ. ὁ δὲ ταῖς μὲν τριήρεσιν ἐπέστησεν ἡγεμόνα Πείσανδρον---τοῦ Πεισάνδρου δὲ ἐτύγχανε συνοικῶν ἀδελφῇ---, τῷ πολέμῳ δὲ αὐτὸς κατὰ γῆν προσεῖχεν ἐρρωμένως.
In a battle against Tissaphernes, the satrap of the region around Ionia, fought on the plain of the Hermus, Agesilaus defeated both the Persian cavalry and the largest number of infantry troops then gathered since the army of Xerxes, or indeed even earlier, the campaigns of Darius against the Scythians and against Athens. The Lacedaemonians, impressed by Agesilaus' energetic handling of affairs, gave him command also over the fleet. He appointed Pisander admiral of the triremes—Pisander, whose wife's sister he happened to have married—and personally applied himself vigorously to the conduct of the land warfare.
