17. The citizens of Abydus¹ at first, placing their artillery along the walls, not only on land denied approach to the assaulting parties, but rendered the anchorage of the fleet dangerous to the [2] enemy; later, when part of the rampart had been laid in ruins, and, in addition, mines had been driven almost to the inner wall which had been hastily constructed, they sent ambassadors to the king regarding terms of surrender for the [3] city. They proposed, however, that they be allowed to send away the Rhodian quadrireme with the naval allies, and the garrison of Attalus, and that they be permitted to leave the city with one garment [4] each. [p. 53]When Philip answered them that there would² no peace without their unconditional surrender, the message when reported kindled such passion, arising from anger and despair together, that, imitating [5] the madness of the Saguntines, they ordered all the matrons to be shut up in the temple of Diana, the free-born boys and maidens and even the young babes with their nurses in the gymnasium, the gold and [6] silver to be collected in the market-place and the valuable garments to be placed on the Rhodian and Cyzicene ships which were in the harbour, the priests and victims to be brought and the altars erected for [7] sacrifice. Then they chose certain men who, when they saw their soldiers slaughtered as they fought before the ruined wall, were forthwith to slay their wives and children, throw into the sea all the gold, silver and garments which [8] were in the ships, and set fire to the public and private buildings in every possible place. This crime they bound themselves by oath to commit, while the priests dictated to them the formula of [9] execration.³ The soldiers then swore that no one would leave the [10] battle-line alive except as victor, and they, mindful of the gods, fought so courageously that, when night was about to end the battle, the king was the first to retire from the field, in fear of their [11] madness. The chiefs, to whom the more cruel part in the crime had been assigned, when they saw only a few surviving the battle, and these exhausted by wounds and weariness, at daybreak sent the priests, wearing their fillets, to surrender the city to Philip.
