B.C. 366-365. Not long after this the Eleians seized Lasion, (9) a place which in old days was theirs, but at present was attached to the Arcadian league. The Arcadians did not make light of the matter, but immediately summoned their troops and rallied to the rescue. Counter-reliefs came also on the side of Elis--their Three Hundred, and again their Four Hundred. (10) The Eleians lay encamped during the day face to face with the invader, but on a somewhat more level position. The Arcadians were thereby induced under cover of night to mount on to the summit of the hill overhanging the Eleians, and at day-dawn they began their descent upon the enemy. The Eleians soon caught sight of the enemy advancing from the vantage ground above them, many times their number; but a sense of shame forbade retreat at such a distance. Presently they came to close quarters; there was a hand-to-hand encounter; the Eleians turned and fled; and in retiring down the difficult ground lost many men and many arms. (9) See above, VII. i. 26; Freeman, "Hist. Fed. Gov." p. 201. (10) From the sequel it would appear that the former were a picked corps of infantry and the latter of cavalry. See Thuc. ii. 25; Busolt, op. cit. p. 175 foll. Flushed with this achievement the Arcadians began marching on the cities of the Acroreia, (11) which, with the exception of Thraustus, they captured, and so reached Olympia. There they made an entrenched camp on the hill of Kronos, established a garrison, and held control over the Olympian hill-country. Margana also, by help of a party inside who gave it up, next fell into their hands. (11) The mountainous district of Elis on the borders of Arcadia, in which the rivers Peneius and Ladon take their rise; see "Dict. of Anct. Geog." s.v.; above, III. ii. 30, IV. ii. 16. Thraustus was one of the four chief townships of the district. For Margana, see above, III. ii. 25, 30, IV. ii. 16, VI. v. 2. These successive advantages gained by their opponents reacted on the Eleians, and threw them altogether into despair. Meanwhile the Arcadians were steadily advancing upon their capital. (12) At length they arrived, and penetrated into the market-place. Here, however, the cavalry and the rest of the Eleians made a stand, drove the enemy out with some loss, and set up a trophy.
