Note 400 — Chapter VIII · (Year of Rome 700.) (Book V. of the “Commentaries.”) MARCH AGAINST THE TREVIRI—SECOND DESCENT IN BRITAIN.

It has appeared to us interesting to explain how Cæsar could join the fleet to his camp.

The Roman camp must have been on flat ground, to allow of the possibility of drawing up the ships of the fleet. Supposing that the mean size of each ship was twenty-five mètres long by six mètres broad, and that the 800 ships composing the fleet had been placed at two mètres from each other, on five lines separated by a distance of three mètres, the fleet would have covered a rectangle of 1,280 mètres by 140, joined with the camp by other trenches. It is, of course, understood that the lightest boats would form the line farthest from the sea.
