34. Philip, judging that he should make some progress towards conciliating the affections of his men, and induce them to face danger more readily on his account, if he [2??] bestowed some pains on the burial of the horsemen who fell in that expedition, ordered them to be conveyed into the camp, in order that all might be spectators of the honours paid them at their funeral. [3] Nothing is so uncertain, or so difficult to form a judgment of, as the minds of the multitude. That which seems calculated to increase their alacrity, in exertions of every sort, often creates in them fear and inactivity. [4] Accordingly, those who, being always accustomed to fight with Greeks and Illyrians, had only seen wounds made with javelins and arrows, seldom even by lances, came to behold bodies dismembered by the Spanish sword, some with their arms lopped off, with the shoulder or the neck entirely cut through, heads severed from the trunk, and the bowels laid open, with other frightful exhibitions of wounds: they therefore perceived, with horror, against what weapons and what men they were to fight. [5] Even the king himself was seized with apprehensions, having never yet engaged the Romans in a regular battle. [6] Wherefore, recalling his son, and the guard posted at the pass of Pelagonia, in order to strengthen his army by the addition of those troops, he thereby opened a passage into Macedonia for Pleuratus and the Dardanians. [7] Then, taking deserters for guides, he marched towards the enemy with twenty thousand foot and four thousand horse, and at the distance of somewhat more than a thousand paces from the Roman camp, and near Ithacus, he fortified a hill with a trench and rampart. [8] From this place, taking a view of the Roman station in the valley beneath, he is said to have been struck with admiration, both at the general appearance of the camp, and the regular disposition of each particular part; then with the disposition of the tents, and the intervals of the passages; and to have declared, that, certainly, that could not be regarded by any as the camp of barbarians. [9] For two days, the consul and the king, each waiting for the other's making some attempt, kept their troops within the ramparts. On the third day, the Roman led out all his forces, and offered battle. [p. 1377]
