Plutarch Titus Flamininus 5

[1] At once, then, the enemy fled precipitately, but not more than two thousand of them fell; ¹ for the difficulties of the ground made pursuit impossible. However, the Romans made spoil of their money, tents, and slaves, mastered the pass, and traversed all parts of Epirus, but in such an orderly manner and with so great restraint that, although they were far from their fleet and the sea, and although their monthly rations of grain had not been measured out to them and they could buy little, they nevertheless refrained from plundering the country, which offered abundant booty.

[2] For Titus had learned that Philip, in passing through Thessaly like a fugitive, was driving the inhabitants from their cities into the mountains, burning down the cities, and allowing his soldiers to plunder the wealth which was too abundant or too heavy to be carried away, thus in a manner ceding the country already to the Romans. Titus was therefore ambitious, and exhorted his soldiers accordingly to spare the country in marching through it, and to treat it as though it had been handed over to them and were their own.

[3] And indeed the results showed them at once the advantages of this orderly conduct. For as soon as they reached Thessaly the cities came over to them, the Greeks south of Thermopylae were all eagerness and excitement to find Titus, and the Achaeans, renouncing their alliance with Philip, voted to join the Romans in making war upon him.

[4] The Opuntians, moreover, although the Aetolians, who were at that time fighting most zealously on the side of the Romans, asked permission to take Opus in charge and protect the city, would not grant the request, but sent for Titus and gave themselves with the fullest confidence into his hands.
  Now, we are told that Pyrrhus, when for the first time he beheld from a look-out place the army of the Romans in full array, had said that he saw nothing barbaric in the Barbarians’ line of battle; ² and so those who for the first time met Titus were compelled to speak in a similar strain.

[5] For they had heard the Macedonians say that a commander a barbarian host was coming against them, who subdued and enslaved everywhere by force of arms; and then, when they met a man who was young in years, humane in aspect, a Greek in voice and language, and a lover of genuine honour, they were wonderfully charmed, and when they returned to their cities they filled them with kindly feelings towards him and the belief that in him they had a champion of their liberties.

[6] After this Titus had a meeting with Philip (who seemed disposed to make terms), and proffered him peace and friendship on condition that he allowed the Greeks to be independent and withdraw his garrisons from their cities; but this proffer Philip would not accept. Then at last it became quite clear even to the partisans of Philip that the Romans were come to wage war, not upon the Greeks, but upon the Macedonians in behalf of the Greeks.
