Synopsis

In this timeline, Hitler decided to launch Operation Sea Lion (a projected Nazi invasion of Great Britain in 1940, shortly after a more devastating version of Dunkirk resulted in a shortage of British Army soldiers. However, due to Winston Churchill's lobbying of President Franklin Roosevelt and his Congress, there is some US military assistance provided. As with France during the First World War, there is only partial occupation of South-Eastern England, and a Nazi "Protectorate of Albion" (analogous to Vichy France in "our" timeline) is established. The Nazis occupy a band of territory that stretches from Portsmouth in the southwest, including communities like Tunbridge Wells, Horsham, Hastings, Pevensey, Dover, Folkestone and Gravesend. They establish a puppet regime in Canterbury led by renegade English Nazi collaborator Lord Haw Haw, and while London remains unoccupied, the adjacent occupation results in the evacuation of senior governmental personnel, politicians, George VI and his royal family to elsewhere in Northern England.
