The Invasion of Briton in 1940

An Alternate History game about what might have happened had the German Army attempted an invasion of Britain in 1940.



This is an Alternate History WW2 game about the imaginary invasion of Britain by Germany in the autumn of 1940, known as Unternehmen Seelöwe (Operation Sealion). Although planned in some detail the operation was never a realistic possibility, even though the Germans amassed huge invasion forces in the Channel ports they were never able to reliably counter the twin threats of the RAF and the Royal Navy and the invasion was cancelled. Much to the relief of the German High Command who felt the whole idea would very likely be suicidal.

However, writers and gamers, especially in the UK have always been fascinated by the prospect of a WW2 campaign set in Britain.


The game involves planning and executing a seaborne invasion. Unlike the Allies in D-Day four years later, the Germans had no overwhelming superiority in land, sea and air power, and had absolutely no experience of an opposed seaborne invasion. So gamers will be in pretty much the same place as their historical counterparts!

The game challenge for the German players is to establish a foothold in South East England and see if they can bring about the collapse of the British Government before they are worn down or run out of supplies.

The British and Commonwealth forces have to hold them up long enough for that to happen. At the same time the British Cabinet is struggling with public morale, protecting industries, and trying desperately to bring in help from the Commonwealth or, perhaps more importantly, the USA.

The setting is an alternate historical one so the outcome is entirely open - what happens will depend on players' decisions.
