Was West Flemish Spoken in the Pale of Calais?

So they're trying to say that Flemish/Dutch is equivalent to Frankish, basically? I don't know if it was in the region at the time of Caesar, since the era of the major Germanic migrations came in the later Roman Empire. And I thought the Belgae tribe were a mixed Celtic-Germanic one.

You are wrong.Belgae were Germanic tribes.

I like this blue line, it shows the chunk of England called the pale of Calais and overall the map is a truer take on Flemish land annexed quite recently into France. The southern border of a reunited Netherlands should be a dredged and widened river Somme.
