51. Delium is a temple of Apollo, overlooking the sea; it is five miles away from Tanagra; the crossing by sea from there to the nearest parts of Euboea is less than four miles. [2] Not only were they in a shrine and sacred grove, of so religious a character, and under the law of sanctuary which protects those temples which the Greeks call “asylums,” but also the war had as yet been neither declared¹ nor brought to such an issue that they had seen swords drawn or blood shed anywhere, while the soldiers [3??] were wandering around completely at ease, some going to see the temple and the grove, some strolling along the shore unarmed, and a great part scattering through the country in quest of wood and forage; [4] suddenly Menippus fell upon them as they straggled here and there and slew them,² and captured about fifty alive; a very few got away, among them Micythio, who was picked up by a small trading-vessel. [5] Just as the loss of the soldiers was annoying to Quinctius and the Romans, so too the affair seemed to have given some further justification for [p. 149]declaring war on Antiochus. [6] Antiochus moved his³ army up to Aulis, and when he had again sent ambassadors to Chalcis, some of his own people and some Aetolians, who urged in more threatening language the same course they had recently advised, although Micythio and Xenoclides vainly strove against it, he easily gained his point that the gates should be opened to him. [7] Those of the Roman party left the city at the approach of the king. The soldiers of the Achaeans and Eumenes held Salganeus, and on the Euripus a few Roman soldiers built a fort to guard the place. Menippus attacked Salganeus, the king himself began to attack the fort on the Euripus. [8] The Achaeans and the soldiers of Eumenes were the first to bargain that they be allowed to depart under safeguard and left their post; with greater stubbornness the Romans tried to hold the Euripus. [9] Nevertheless, even they, when they were besieged by land and sea and saw the engines and artillery being moved forward, did not withstand the siege. [10] Since the king held this, which was the chief city of Euboea, the other cities of the island did not disobey his orders, and he seemed to himself to have made an important start to the war in the fact that so great an island and so many well-situated cities had come under his sway.
