By the end of June 1940 the Battle of France was over, the British Army had been plucked from the Beaches of Dunkirk, but much of its heavy equipment had been abandoned in France.

It looked like Britain would be the next target for the Nazi war machine… Having witnessed the debacle in France a betting man might have put his money on the Germans when it came to invading England.

On the 14th of May 1940 Anthony Eden had called on men between 17 and 65 in Britain who were not in military service but wished to defend their country to enrol in the Local Defence Volunteers. By July over 1.5million Britons has volunteered…

Another group was also created, a clandestine army that in the event of invasion would be called upon. Britain would be the first nation to have a pre-planed resistance network, the went under the unassuming name of Auxiliary, or Aux Units.
