The various nations of Germany and Sarmatia, who fought under the Gothic standard, had already collected an armament more formidable than any which had yet issued from the Euxine. On the banks of the Niester, one of the great rivers that discharge themselves into that sea, they constructed a fleet of two thousand, or even of six thousand vessels; numbers which, however incredible they may seem, would have been insufficient to transport their pretended army of three hundred and twenty thousand barbarians. Whatever might be the real strength of the Goths, the vigor and success of the expedition were not adequate to the greatness of the preparations. In their passage through the Bosphorus, the unskilful pilots were overpowered by the violence of the current; and while the multitude of their ships were crowded in a narrow channel, many were dashed against each other, or against the shore. The barbarians made several descents on the coasts both of Europe and Asia; but the open country was already plundered, and they were repulsed with shame and loss from the fortified cities which they assaulted. A spirit of discouragement and division arose in the fleet, and some of their chiefs sailed away towards the islands of Crete and Cyprus; but the main body, pursuing a more steady course, anchored at length near the foot of Mount Athos, and assaulted the city of Thessalonica, the wealthy capital of all the Macedonian provinces. Their attacks, in which they displayed a fierce but artless bravery, were soon interrupted by the rapid approach of Claudius, hastening to a scene of action that deserved the presence of a warlike prince at the head of the remaining powers of the empire. Impatient for battle, the Goths immediately broke up their camp, relinquished the siege of Thessalonica, left their navy at the foot of Mount Athos, traversed the hills of Macedonia, and pressed forwards to engage the last defence of Italy.
