Meanwhile the Mantineans had taken the field against Orchomenus; but from the walls of that city the invaders had some difficulty in retiring, and lost some of their men. On their retreat they found themselves in Elymia; (13) here the heavy infantry of the Orchomenians ceased to follow them; but Polytropus and his troops continued to assail their rear with much audacity. At this conjuncture, seeing at a glance that either they must beat back the foe or suffer their own men to be shot down, the Mantineans turned right about and met the assailant in a hand-to-hand encounter. Polytropus fell fighting on that battlefield; and of the rest who took to flight, many would have shared his fate, but for the opportune arrival of the Phliasian cavalry, who swooped round to the conqueror's rear and checked him in his pursuit. (14) (13) Elymia, mentioned only by Xenophon, must have been on the confines of the Mantinice and Orchomenus, probably at Levidhi.-- Leake, "Morea," iii. 75; "Peloponn." p. 229. (14) See "Cyrop." VII. i. 36. Content with this achievement, the Mantineans retired homewards; while Agesilaus, to whom the news was brought, no longer expecting that the Orchomenian mercenaries could effect a junction with himself, determined to advance without further delay. (15) On the first day he encamped for the evening meal in the open country of Tegea, and the day following crossed into Mantinean territory. Here he encamped under the westward-facing (16) mountains of Mantinea, and employed himself in ravaging the country district and sacking the farmsteads; while the troops of the Arcadians who were mustered in Asea stole by night into Tegea. The next day Agesilaus shifted his position, encamping about two miles' (17) distance from Mantinea; and the Arcadians, issuing from Tegea and clinging to the mountains between Mantinea and that city, appeared with large bodies of heavy infantry, wishing to effect a junction with the Mantineans. The Argives, it is true, supported them, but they were not in full force. And here counsellors were to be found who urged on Agesilaus to attack these troops separately; but fearing lest, in proportion as he pressed on to engage them, the Mantineans might issue from the city behind and attack him on flank and rear, he decided it was best to let the two bodies coalesce, and then, if they would accept battle, to engage them on an open and fair field.
