Thus the winter passed away. With the spring of 555 the proconsul Publius Sulpicius broke up from his winter camp, determined to conduct his legions from Apollonia by the shortest route into Macedonia proper. This principal attack from the west was to be supported by three subordinate attacks; on the north by an invasion of the Dardani and Illyrians; on the east by an attack on the part of the combined fleet of the Romans and allies, which assembled at Aegina; while lastly the Athamanes, and the Aetolians also, if the attempt to induce them to share in the struggle should prove successful, were to advance from the south. After Galba had crossed the mountains pierced by the Apsus (now the Beratind), and had marched through the fertile plain of Dassaretia, he reached the mountain range which separates Illyria from Macedonia, and crossing it, entered the proper Macedonian territory. Philip had marched to meet him; but in the extensive and thinly- peopled regions of Macedonia the antagonists for a time sought each other in vain; at length they met in the province of Lyncestis, a fertile but marshy plain not far from the north-western frontier, and encamped not 1000 paces apart. Philip's army, after he had been joined by the corps detached to occupy the northern passes, numbered about 20,000 infantry and 2000 cavalry; the Roman army was nearly as strong. The Macedonians however had the great advantage, that, fighting in their native land and well acquainted with its highways and byways, they had little trouble in procuring supplies of provisions, while they had encamped so close to the Romans that the latter could not venture to disperse for any extensive foraging. The consul repeatedly offered battle, but the king persisted in declining it; and the combats between the light troops, although the Romans gained some advantages in them, produced no material alteration. Galba was obliged to break up his camp and to pitch another eight miles off at Octolophus, where he conceived that he could more easily procure supplies. But here too the divisions sent out were destroyed by the light troops and cavalry of the Macedonians; the legions were obliged to come to their help, whereupon the Macedonian vanguard, which had advanced too far, were driven back to their camp with heavy loss; the king himself lost his horse in the action, and only saved his life through the magnanimous self-devotion of one of his troopers. From this perilous position the Romans were liberated through the better success of the subordinate attacks which Galba had directed the allies to make, or rather through the weakness of the Macedonian forces. Although Philip had instituted levies as large as possible in his own dominions, and had enlisted Roman deserters and other mercenaries, he had not been able to bring into the field (over and above the garrisons in Asia Minor and Thrace) more than the army, with which in person he confronted the consul;
