Seeing how his schemes had miscarried, Perseus sent his two naval commanders, Antenor and Calippus, with forty swift ships and five cutters to Tenedos to protect the corn ships which were making their way to Macedonia through the scattered groups of the Cyclades. The ships took the water at Cassandrea, in the two harbours under Mount Athos, and from there sailed to Tenedos in a calm sea. Some undecked vessels belonging to Rhodes were lying in the harbour and Eudamus, their commander, was allowed to take them away unharmed, as though they were friends. On learning that fifty of his transports on the other side of the island were blockaded by the war-galleys of Eumenes which were stationed at the entrance to the harbour, Antenor promptly sailed round and the enemy ships made off on his appearance. Ten swift ships were told off to escort the transports to Macedonia, and when they had seen them safe they were to return to Tenedos. Eight days afterwards they rejoined the fleet which was now anchored off Sigeum. From here they sailed to Sabota, an island situated between Elaea and Chios. The day after they arrived, thirty-five vessels called "hippagogi," carrying Gaulish horses and troopers, happened to be on their way from Elaea to Phanae, a headland in Chios, intending to sail from there to Macedonia. They were sent to Attalus by Eumenes. When Antenor received a signal that these ships were at sea, he started for Sabota and met them in the narrowest part of the channel between the headland of Erythrae and Chios. The last thing that Eumenes's officers expected was the appearance of a Macedonian fleet cruising in those waters. They first thought that they were Romans and then that it was Attalus or some that had been sent back by Attalus from the Roman camp and were on their way to Pergamum. But when the build of the approaching vessels could no longer be mistaken and the prows steering straight for them at increasing speed revealed the approach of an enemy, there was great alarm. The clumsy nature of their ships and the difficulty of keeping the Gauls quiet, destroyed all hope of resistance. Some of those who were nearer to the mainland swam to Erythrae; others crowded on all sail and ran their ships aground in Chios, and, abandoning the horses, fled in wild disorder towards the city. But the Macedonian vessels, taking a shorter course, landed their marines nearer the city and some of the Gauls were cut down as they fled along the road, others outside the city gate. The Chians had closed their gates, not knowing who were fleeing and who were pursuing. Nearly 800 Gauls were killed and 200 made prisoners. Some of the horses in the wrecked ships were drowned; others were hamstrung by the Macedonians on the beach. There were twenty horses of exceptional beauty, and Antenor gave orders for the ten vessels which he had previously sent to carry these and the prisoners to Thessalonica and return as soon as possible; he should wait for them at Phanae. The fleet lay off Chios for three days and then sailed to Phanae. The ten ships returned sooner than was expected; the whole fleet then put out to sea and sailed across the Aegean to Delos.
