C. Julius Caesar, Gallic War

But Caesar, although he had not as yet discovered their measures, yet, both from what had occurred to his ships, and from the circumstance that they had neglected to give the promised hostages, suspected that the thing would come to pass which really did happen. He therefore provided remedies against all contingencies; for he daily conveyed corn from the country parts into the camp, used the timber and brass of such ships as were most seriously damaged for repairing the rest, and ordered whatever things besides were necessary for this object to be brought to him from the continent. And thus, since that business was executed by the soldiers with the greatest energy, he effected that, after the loss of twelve ships, a voyage could be made well enough in the rest.
