During these operations the Roman commissioners, C. Popilius, C. Decimius and C. Hostilius, left Chalcis with three quinqueremes and arrived at Delos. There they found the forty vessels belonging to the Macedonians and five quinqueremes belonging to Eumenes. The sanctity of the temple and the island prevented them from injuring one another. The Romans, the Macedonians and the crews from Eumenes' ships went about together in the city and the temple in the peaceful security of a locality sacred and inviolate. Antenor received a signal from the look-out that several transports were sailing past. He started in pursuit with some of his ships and dispersed the rest among the Cyclades. He either sunk or plundered them all, with the exception of those heading for Macedonia. Popilius tried to save all he could, both of his own ships and those of Eumenes, but the Macedonian barques sailed by night, two or three together, and so escaped observation. About this time the Macedonian and Illyrian envoys arrived in Rhodes. Their representations had all the more weight owing to the appearance of the Macedonian ships cruising amongst the Cyclades and in the Aegean, the united action which Perseus and Gentius were taking, and the rumour that the Gauls were coming with a large force of infantry and cavalry. Dinon and Polyaratus, the leaders of Perseus' faction, felt themselves now strong enough to send a favourable reply to the two monarchs, and even went so far as to proclaim publicly that they possessed sufficient authority to put an end to the war, the kings themselves therefore must resign themselves to the acceptance of peace terms.
