23. With no less suffering of beasts and men than when he had come, the king returned to Macedonia; Appius, however, was drawn away from the siege of Phanote by the report that Perseus was marching on Stratus. [2] Cleuas, following with a force of vigorous young men beneath the almost impassable spurs of the mountains, killed about a thousand men of the burdened column and captured about two hundred. [3] After passing over the narrows, Appius remained in camp a few days in the plain which they call Meleon. Meanwhile Cleuas, taking along Philostratus, who had five hundred of the Epirote people, crossed over to the territory of [p. 83]Antigonea. [4] The Macedonians set out to plunder;¹ Philostratus with his detachment settled down in ambush in a hidden spot. When armed men sallied forth from Antigonea against the scattered plunderers, as they pursued in too open order after these fugitives, they burst into the valley ambushed by the enemy. [5] After the killing there of about a thousand and the capturing of nearly a hundred, the campaign was successfully conducted everywhere, and they moved their camp near the settled camp of Appius, so that no violence might be inflicted by the Roman army on their allies. [6] Appius, who was wasting time to no purpose in these parts, after sending away the forces of Chaonians, The sprotians and whatever other Epirotes there were, retired to Illyricum with his Italian soldiers, divided his men in winter-quarters among the allied cities of the Parthini, and himself returned to Rome to offer sacrifices. [7] Perseus sent to Cassandrea to act as its garrison a thousand infantry and two hundred cavalry recalled from the people of the Penestae. The envoys returned from Gentius with the same reply. [8] On the one hand, Perseus did not cease thereafter to make overtures to him by sending embassy after embassy, and, on the other hand, although it was obvious how much reinforcement Gentius could provide, yet he could not induce himself to incur expense for a matter of the greatest importance in every respect.²
