the town with such haste that the slain victims were left lying on the spot.[65] Having thus driven in the defenders, Alexander was preparing to draw a wall of circumvallation round the Pelion, when he was interrupted by the arrival of Glaukias with so large a force as to compel him to abandon the project. A body of cavalry, sent out from the Macedonian camp under Philotas to forage, were in danger of being cut off by Glaukias, and were only rescued by the arrival of Alexander himself with a reinforcement. In the face of this superior force, it was necessary to bring off the Macedonian army, through a narrow line of road along the river Eordaikus, where in some places there was only room for four abreast, with hill or marsh everywhere around. By a series of bold and skilful manœuvres, and by effective employment of his battering-train or projectile machines to protect the rear-guard, Alexander completely baffled the enemy, and brought off his army without loss.[66] Moreover these Illyrians, who had not known how to make use of such advantages of position, abandoned themselves to disorder as soon as their enemy had retreated, neglecting all precautions for the safety of their camp. Apprised of this carelessness, Alexander made a forced night-march back, at the head of his Agrianian division and light troops supported by the remaining army. He surprised the Illyrians in their camp before daylight. The success of this attack against a sleeping and unguarded army was so complete, that the Illyrians fled at once without resistance. Many were slain or taken prisoners; the rest, throwing away their arms, hurried away homeward, pursued by Alexander for a considerable distance. The Illyrian prince Kleitus was forced to evacuate Pelion, which place he burned, and then retired into the territory of Glaukias.[67] [63] For the situation of Pelion, compare Livy, xxxi. 33, 34, and the remarks of Colonel Leake, Travels in Northern Greece, vol. iii. ch. 28. p. 310-324. [64] Assuming Alexander to have been in the Territory of the Triballi, the modern Servia, he would in this march follow mainly the road which is now frequented between Belgrade and Bitolia; through the plain of Kossovo, Pristina, Katschanik (rounding on the north-eastern side the Ljubatrin, the north-eastern promontory terminating the chain of Skardus), Uschkub, Kuprili, along the higher course of the Axius or Vardar, until the point where the Erigon or Tscherna joins that river below Kuprili. Here he would be among the Pæonians and Agrianes, on the east—and the Dardani and Autariatæ, seemingly on the north and west. If he then followed the course of the Erigon, he would pass through the portions of Macedonia then called Deuripia and Pelagonia: he would go between the ridges of the mountains, through which the Erigon breaks, called Nidje on the south, and Babuna on the north. He would pass afterwards to Florina, and not to Bitolia.
