Among the episodes from Caesar's De Bello Gallico that strike a Dutchman most (and this will equally apply to the English, I suppose) are those that treat of the sea. When we read how at the landing in Britain the Roman ships are too large to reach the coast, and how the soldiers leap from the vessels and wade fighting through the water, we can vividly imagine such a scene. Not that we see troops land every day, all Dutchmen are acquainted with the North Sea and its flat beach, so that a perusal of this passage evokes familiar ideas. Personally I find the episode of Caesar's campaign against the maritime States in Brittany very interesting. Now we discover a very similar situation in our own regions, then again we come across differences. Driven by a desire for personal observation we set out to this part of France during the summer holidays to see if Caesar's description agrees with the present situation, and how far the aspect of modern Brittany elucidates the passage in Caesar. And this has in no small measure proved to be the case.
