achieved by his cavalry were far from affording compensation. Still more unfavourable than in Phrygia was the aspect of things for the Romans on the north coast of Asia Minor. Here the great Pontic army and the fleet had completely mastered Bithynia, and compelled the Roman consul Cotta to take shelter with his far from numerous force and his ships within the walls and port of Chalcedon, where Mithradates kept them blockaded. The Romans Defeated at Chalcedon This blockade, however, was so far a favourable event for the Romans, as, if Cotta detained the Pontic army before Chalcedon and Lucullus proceeded also thither, the whole Roman forces might unite at Chalcedon and compel the decision of arms there rather than in the distant and impassable region of Pontus. Lucullus did take the route for Chalcedon; but Cotta, with the view of executing a great feat at his own hand before the arrival of his colleague, ordered his admiral Publius Rutilius Nudus to make a sally, which not only ended in a bloody defeat of the Romans, but also enabled the Pontic force to attack the harbour, to break the chain which closed it, and to burn all the Roman vessels of war which were there, nearly seventy in number. On the news of these misfortunes reaching Lucullus at the river Sangarius, he accelerated his march to the great discontent of his soldiers, in whose opinion Cotta was of no moment, and who would far rather have plundered an undefended country than have taught their comrades to conquer. His arrival made up in part for the misfortunes sustained: the king raised the siege of Chalcedon, but did not retreat to Pontus; he went southward into the old Roman province, where he spread his army along the Propontis and the Hellespont, occupied Lampsacus, and began to besiege the large and wealthy town of Cyzicus. He thus entangled himself more and more deeply in the blind alley which he had chosen to enter, instead of--which alone promised success for him--bringing the wide distances into play against the Romans.
