The attack on Britain was at length made by the principal squadron, which, under the command of the prefect Asclepiodotus, an officer of distinguished merit, had been assembled in the mouth of the Seine. So imperfect in those times was the art of navigation that orators have celebrated the daring courage of the Romans, who ventured to set sail with a side-wind, and on a stormy day. The weather proved favorable to their exercise. Under the cover of a thick fog, they escaped the fleet of Allectus, which had been stationed off the Isle of Wight to receive them, landed in safety on some part of the western coast, and convinced the Britons that a superiority of naval strength will not always protect their country from a foreign invasion. Asclepiodotus had no sooner disembarked the Imperial troops than he set fire to his ships, and, as the expedition turned fortunate, his heroic conduct was universally admired.
