Leaving Mardonius in Thessaly, where he proposed to winter, Xerxes now hastened home. Sixty thousand Persians under Artabazus accompanied the king only as far as the passage into Asia; and it was with an inconsiderable force, which, pressed by famine, devastated the very herbage on their way, and which a pestilence and the dysentery diminished as it passed, that the great king crossed the Hellespont, on which the bridge of boats had already been broken by wind and storm. A more abundant supply of provisions than they had yet experienced tempted the army to excesses, to which many fell victims. The rest arrived at Sardis with Xerxes, whence he afterward returned to his more distant capital. XXII. The people of Potidaea, on the Isthmus of Pallene, and Olynthus, inhabited by the Bottiaeans, a dubious and mongrel race, that boasted their origin from those Athenians who, in the traditional ages, had been sent as tributary captives to the Cretan Minos, no sooner learned the dispersion of the fleet at Salamis, and the retreat of the king, than they openly revolted from the barbarian. Artabazus, returning from the Hellespont, laid siege to Olynthus, massacred the inhabitants, and colonized the town with Chalcidians. He then sat down before Potidaea; but a terrible inundation of the sea, with the sallies of the besieged, destroyed the greater number of the unfortunate invaders. The remnant were conducted by Artabazus into Thessaly, to join the army of Mardonius. The Persian fleet, retreating from Salamis, after passing over the king and his forces from the Chersonese to Abydos, wintered at Cuma; and at the commencement of the spring assembled at Samos. Meanwhile the Athenians returned to their dismantled city, and directed their attention to its repair and reconstruction. It was then, too, that in all probability the people hastened, by a formal and solemn reversal of the sentence of ostracism, to reward the services of Aristides, and to restore to the commonwealth the most spotless of its citizens.
