de bello gallico, 4.29

In the same night it happened that the moon was clear, which day accustomed to make the greatest maritime tides in the ocean, and this was unknown to us. Thus at one time both had the tide had filled the war ships by which Caesar had taken care that his army must be transported, and which he had lead up on dry land, and a storm was afflicting the transport ships, which were bound to anchors, and there was not any means given to us either of managing or of aiding (the ships). With very many ships having been broken, and because the rest were unusable for sailing—the ropes, anchors, and remaining equipment having been lost—this which was necessary to happen, a great uproar of the whole army occurred. For neither were there other ships by which they could be carried back and all things were lacking which was for use for repairing ships and, because it was evident to everyone that they ought to winter in Gaul, grain had not been provided for in these locations for the winter.
