1. Assuming the RAF lost the BoB, the luftwaffe gained air superiority to clear the English channel sufficiently to allow a wehrmacht crossing in autumn 1940. Over the course of the winter and spring of 1941 they defeat the UK and force an armistice which results in enforced neutrality for the UK, knocking them out of the war (similar to that enforced on France).
2. Operation Barbarossa takes place in May 1941 (historically this was the set time but was delayed due to a British inspired coup in Yugoslavia which forced the wehrmacht south for a month long delay).
3. With no enemy across the channel the Germans don't need to occupy the north and western sides of France or to start construction of the Atlantic Wall. However I think they would decide to station garrisons in the UK and France anyway.
4. I would envisage that once Hitler turned his army eastward he would leave the western theatre almost entirely to the Kriegsmarine and Luftwaffe and these organisations would build up ground forces for defence.
So heres the question, How would the US conduct an invasion of liberation across the Atlantic without a friendly island staging post? They conducted many long range invasions in the Pacific but they were of small islands, easily cut off, and the set invasion of Japan itself prompted the use of nukes.
Would such an invasion be possible and sustainable? (the Kriegsmarine would have little else to do but guard the eastern shores of Europe and their only enemy would be the USN).
This was the initial premise of this hypothetical scenario, to answer those who have commented on the nature of the British capitulation. It supposes that Britain was successfully invaded and defeated in the winter and spring of 1941 and then forced into surrender and sort of neutrality just like what the Germans did with France after they defeated them (Vichy France et al).
From this it supposes that the mainland of Britain would have to be occupied like France in order to keep both populations in line.
The reaction of British overseas possessions and the military forces there (RN, RAF, Army etc) to the defeat and occupation of Britain would be similar to those seen by French overseas territories (some would fight on, some would capitulate). British ex-dominion territories like Canada and Australia were independant countries and Allies of Britain, whether they would fight on or not is part of the question and thus left to those who want to reply to make their case for whatever scenario conclusion they choose to.
Essentially put I started the thread with Britain and France (not necessarily their empires included) defeated and occupied and Barbarossa started in May 41 and let everybody run with it.
I doubt very much that British military forces like the French would actually switch sides and start fighting for the Germans, those that capitulated would be demobbed. Of course some few nazi sympathizers would form Waffen SS Legions, like what happened in all German occupied countries.
One point that hasn't been mentioned regarding Barbarossa. It is not IMO a matter of numbers or tactical skill that really counts when invading Russia as much as timing, specifically time scale. The real concern for any invasion is the weather and the mud (the Rasputitsa), the Germans could have sent in a million more men but would still have failed because of the weather and the inability of their vehicles to move during the spring and autumn, German weapons froze during the winter.
The only real opportunity to invade Russia successfully would be during the few summer months, so the earlier than historical intended time of May rather than June would be more significant than greater numbers.
