Romans and king Attalus carried on their attacks against Oreus on different sides; the Romans against the citadel next to the sea, the king's troops against the lower part of the town, lying between the two citadels, where the city is also divided by a wall. As their posts were different, so were their methods of attack: the Romans made their approaches by means of covered galleries, applying also the ram to the walls; the king's troops, by throwing in weapons with the balista, catapulta, and every other kind of engine, and stones also of immense weight. They formed mines, too, and made use of every expedient, which, on trial, had been found useful in the former siege. On the other side, not only did more Macedonians protect the town and the citadels, than on the former occasion, but they exerted themselves with greater spirit, in consequence of the reprimands which they had received from the king for the misconduct they had committed, and also from remembrance both of his threats and promises with regard to the future. Thus, when time was being consumed there, contrary to their expectation, and there was more hope from a siege and works than from a sudden assault, the lieutenant-general thought that in the mean time some other business might be accomplished; wherefore, leaving such a number of men as seemed sufficient to finish the works, he passed over to the nearest part of the continent, and, arriving unexpectedly, made himself master of Larissa, except the citadel,--not that celebrated city in Thessaly, but another, which they call Cremaste. Attalus also surprised Aegeleos, where nothing was less apprehended than such an enterprise during the siege of another city. The works at Oreus had now begun to take effect, while the garrison within were almost spent with unremitted toil, (keeping watch both by day and night,) and also with wounds. Part of the wall, being loosened by the strokes of the ram, had fallen down in many places; and the Romans, during the night, broke into the citadel through the breach which lay over the harbour. Attalus, likewise, at the first light, on a signal given from the citadel by the Romans, himself also assaulted the city, where great part of the walls had been levelled; on which the garrison and townsmen fled into the other citadel, and a surrender was made two days after. The city fell to the king, the prisoners to the Romans.
