C. Julius Caesar, Gallic War

When these things were done [and] Labienus, left on the continent with three legions and 2,000 horse, to defend the harbors and provide corn, and discover what was going on in Gaul, and take measures according to the occasion and according to the circumstance; he himself, with five legions and a number of horse, equal to that which he was leaving on the continent, set sail at sun-set, and [though for a time] borne forward by a gentle south-west wind, he did not maintain his course, in consequence of the wind dying away about midnight, and being carried on too far by the tide, when the sun rose, espied Britain passed on his left. Then, again, following the change of tide, he urged on with the oars that he might make that part of the island in which he had discovered the preceding summer, that there was the best landing-place, and in this affair the spirit of our soldiers was very much to be extolled; for they with the transports and heavy ships, the labor of rowing not being [for a moment] discontinued, equaled the speed of the ships of war. All the ships reached Britain nearly at mid-day; nor was there seen a [single] enemy in that place, but, as Caesar afterward found from some prisoners, though large bodies of troops had assembled there, yet being alarmed by the great number of our ships, more than eight hundred of which, including the ships of the preceding year, and those private vessels which each had built for his own convenience, had appeared at one time, they had quitted the coast and concealed themselves among the higher points.
