In the next summer Agis undertook a second expedition, accompanied on this occasion by all the allies of Sparta; even by the Athenians, now enrolled upon the list. Thebes and Corinth alone stood aloof. On this occasion he approached from the opposite or southern side, that of the territory once called Messenia; passing through Aulon, and crossing the river Neda. He marched through Triphylia to the river Alpheius, which he crossed, and then proceeded to Olympia, where he consummated the sacrifice from which the Eleians had before excluded him. In his march he was joined by the inhabitants of Lepreum, Makistus, and other dependent towns, which now threw off their subjection to Elis. Thus reinforced, Agis proceeded onward towards the city of Elis, through a productive country under flourishing agriculture, enriched by the crowds and sacrifices at the neighboring Olympic temple, and for a long period unassailed. After attacking, not very vigorously, the half-fortified city,—and being repelled by the Ætolian auxiliaries,—he marched onward to the harbor called Kyllênê, still plundering the territory. So ample was the stock of slaves, cattle, and rural wealth generally, that his troops not only acquired riches for themselves by plunder, but were also joined by many Arcadian and Achæan volunteers, who crowded in to partake of the golden harvest.[396] [396] Xen. Hellen. iii, 2, 23, 26; Diodor. xiv, 17. The opposition or wealthy oligarchical party in Elis availed themselves of this juncture to take arms against the government; hoping to get possession of the city, and to maintain themselves in power by the aid of Sparta. Xenias their leader, a man of immense wealth, with several of his adherents, rushed out armed, and assailed the government-house, in which it appears that Thrasydæus and his colleagues had been banqueting. They slew several persons, and among them one, whom, from great personal resemblance, they mistook for Thrasydæus. The latter was however at that moment intoxicated, and asleep in a separate chamber.[397] They then assembled in arms in the market-place, believing themselves to be masters of the city; while the people, under the like impression that Thrasydæus was dead, were too much dismayed to offer resistance. But presently it became known that he was yet alive; the people crowded to the government-house “like a swarm of bees,”[398] and arrayed themselves for his protection as well as under his guidance. Leading them forth at once to battle, he completely defeated the oligarchical insurgents, and forced them to flee for protection to the Lacedæmonian army. [397] Xen.
