The Pas de Calais thread got me wondering - where else could the Allies have realistically chosen to launch D-Day?
Aside from "it's closer to Paris and Germany," was there a reason they landed east of the Cotentin Peninsula instead of west? What about Brittany, Belgium or the Netherlands (north of the Rhine, say around Leiden or thereabouts) - did logistics on the Allied side and the Atlantic Wall and unit concentration on the German make them non-starters?
