Against an attack from behind the phalanx was defenceless, and this movement ended the battle.

From the complete breaking up of the two phalanxes we may well believe that the Macedonian loss amounted to 13,000, partly prisoners, partly fallen--but chiefly the latter, because the Roman soldiers were not acquainted with the Macedonian sign of surrender, the raising of the -sarissae-.

The loss of the victors was slight.

Philip escaped to Larissa, and, after burning all his papers that nobody might be compromised, evacuated Thessaly and returned home.
Simultaneously with this great defeat, the Macedonians suffered other discomfitures at all the points which they still occupied; in Caria the Rhodian mercenaries defeated the Macedonian corps stationed there and compelled it to shut itself up in Stratonicea; the Corinthian garrison was defeated by Nicostratus and his Achaeans with severe loss, and Leucas in Acarnania was taken by assault after a heroic resistance.

Philip was completely vanquished; his last allies, the Acarnanians, yielded on the news of the battle of Cynoscephalae.
Preliminaries of Peace It was completely in the power of the Romans to dictate peace; they used their power without abusing it.
