Interesting idea. The RN is large, and usually only fully decimated by luftwaffe bomber attacks. The carriers keep them at bay, and can cause some serious repair damage, but the bombers (CAS and TACs - no NAVs in '39-40) are the killers.What I meant was: if the RN is far away and leaves the North Sea undefended, yet you do not have yet the forces available for a full scale sea lion, what about a landing in Scotland? The idea would be, that your troops dig in at chokepoints to hold out, until more forces are available. Also, the idea would be to fly your air units over to airbases in Scotland and both aid the ground troops in fending of attacks and attack returning RN ships in the area. Never tried it myself, just wondering if it would be feasible in that specific case on a Royal Navy that is absent in the early war because it aids in the invasion of Spanish North Africa.
There will be a second large fleet in Scapa Flow, or their East Coast, which is impossible to bomb. Their biggest fleet has an uncanny way of showing up at the entrance th the Channel about 1 day or so into Sealion. This time Franco couldn't win his war, so I had to DOW RS right after VF - Mid October '39. I rushed an attempt around 10/28/39 and guess who showed up as predicted? Lost Marines = retry later! I could wait until March - doing Denmark & Norway and try to crush the UK fleet that way, but once they detect my CVs they bug out, unless it's their own homeland being hit. Understandable.
