de bello gallico, 4.31

And so, he was gathering supplies for all emergencies. For both he was bringing together grain from the fields daily into camp and, which ships were most seriously damaged, of these he was using the materials and bronze for the fixing of the rest, and, what things were for use for these things, he ordered be carried from the continent. And so, because it was taken care of by the soldiers with the greatest zeal, with twelve ships having been lost, he made it so that with the rest it could be sailed fairly well.
