§ Mr. Galbraith
To ask the Secretary of State for Defence if, in the light of post-war examination and research, he will redefine the official time for the end of the battle of Britain.
§ Mr. Archie Hamilton
The term "Battle of Britain" refers to the threatened invasion in 1940. German plans never got beyond the first phase, an air assault intended to pave the way for the invasion by driving the RAF from the sky. By 17 September the heavy Luftwaffe losses forced Hitler to put off his invasion plans. Photo-reconnaissance on 20 September showed the German invasion fleet dispersing, and an Enigma decrypt on 25 October confirmed that invasion units had been disbanded. On 31 October the Defence Committee under Winston Churchill confirmed that the danger of invasion was over, and this day became the official end-date for the battle of Britain. All subsequent evidence has confirmed this decision and there would be no grounds for a redefinition.
