Invasion 1941. Factual and counter-factual. Hitler decides the British Empire first - Russia can wait. All factual and taken from 'what was possible' with 'what was available'. No 'impossible' scenarios. Half a million (from an army of 3 million) Storm troopers and an overwhelming superiority in arms and equipment. How can it fail? Atlas D'four lays it 'all' bare. The facts speak for themselves.
