In 1940 [[Denmark]] and [[Norway]] were invaded by German forces, to preempt a British occupation of Norway. Norway also contained a source of [[Heavy water]], possibly crucial in the construction of an atomic weapon. This was soon followed by the British invasion of neutral [[Iceland]] (the invasion of [[Denmark]] by German forces marks the start of an independent Iceland).

With Britain the sole opposing European nation, the [[Battle of Britain]] commenced. The [[Luftwaffe]] attempted to achieve aerial dominance over the south of Britain, in order to allow a sea based invasion of Britain to proceed. For many months the [[Royal Air Force]] and Luftwaffe fought for dominance, with the resilience of the RAF, with British, Canadian and [[Republic of Poland|London Polish exile]] pilots forced a rethink of [[German]] tactics. The period that followed is known as the [[Blitz]], where the RAF and Luftwaffe attempted to undermine the infrastructure of the opposing country. This was a period of great economic devastation, which took both countries a considerable period to recover from. More seriously it led to huge numbers of civilian deaths.
