But Alexander formed a plan by which he might cross the mountain with the least danger possible; and since he was resolved to run all risks, knowing that there were no means of passing elsewhere, he ordered the heavy-armed soldiers, as soon as the waggons began to rush down the declivity, to open their ranks, and directed that those whom the road was sufficiently wide to permit to do so should stand apart, so that the waggons might roll through the gap; but that those who were hemmed in on all sides should either stoop down together or even fall flat on the ground, and lock their shields compactly together, so that the waggons rushing down upon them, and in all probability by their very impetus leaping over them, might pass on without injuring them. And it turned out just as Alexander had conjectured and exhorted. For some of the men made gaps in the phalanx, and others locked their shields together. The waggons rolled over the shields without doing much injury, not a single man being killed under them. Then the Macedonians regained their courage, inasmuch as the waggons, which they had excessively dreaded, had inflicted no damage upon them. With a loud cry they assaulted the Thracians. Alexander ordered his archers to march from the right wing in front of the rest of the phalanx, because there the passage was easier, and to shoot at the Thracians where they advanced. He himself took his own guard, the shield-bearing infantry and the Agrianians,[26] and led them to the left. Then the archers shot at the Thracians who sallied forward, and repulsed them; and the phalanx, coming to close fighting, easily drove away from their position men who were light-armed and badly equipped barbarians. The consequence was, they no longer waited to receive Alexander marching against them from the left, but casting away their arms they fled down the mountain as each man best could. About 1,500 of them were killed; but only a few were taken prisoners on account of their swiftness of foot and acquaintance with the country. However, all the women who were accompanying them were captured, as were also their children and all their booty. CHAPTER II. BATTLE WITH THE TRIBALLIANS.
