[103] When the stratagem became manifest Norbanus and Decidius occupied the gorge of the Sapæans strongly. Again Brutus and Cassius could find no passage. They fell into discouragement lest they should now have to begin the roundabout journey which they had disdained, and to turn upon their own tracks, although pressed by time and the lateness of the season. While they were in this mood Rhascupolis said that there was a circuitous route (along the very side of the Sapæan mountain) of three days' march, which had been impassable to men up to this time on account of rocks, scarcity of water, and dense forests. If they would carry their water and make a narrow but sufficient pathway, they would be so enveloped in shade that they would not be perceived even by birds. On the fourth day they would come to the river Harpessus, which falls into the Hebrus, and in one day more they would be at Philippi, flanking the enemy so as to cut him off completely and leave him no chance to retreat. They adopted this plan since there was nothing else to do, and especially because it held out the hope of surrounding so large a force of the enemy.
