So awhile back I was playing an alt-interwar nation game as the UK, and needed to invade France (long story). Since the obvious move would be to repeat OTL and go for Normandy or Calais, I decided to go the non-obvious route and aim for the Cote d'Argent off the Bay of Biscay. It worked out alright in the game, but I've been turning it over in my head ever since, and figured it couldn't hurt to ask.
So, basically, could/would the WAllies have invaded the Cote d'Argent, as an alternative to either Overlord or Dragoon? As far as landing sites go, the Cote d'Argent isn't that bad: long flat beach, no cliffs (so the Atlantic Wall won't be as great a threat), close to two ports that can be captured (Bordeaux and Arcahon), and was (as I understsand it) relatively under-defended. While it doesn't really work as an alternative to Normandy (too far from Paris and, more importantly, the German border), it would be a solid alternate to Dragoon, and one that would not require the securing of North Africa to stage (it would, however, probably need an at least solidly pro-Allied Portugal).
So, invading the Cote d'Argent: good idea or Frisian Island II: Electric Boogaloo?
