what date did britain declare war on germany
British and French declaration of war on Germany The Declaration of war by France and the United Kingdom was given on 3 September 1939, after German forces invaded Poland. Despite the speech being the official announcement of both France and the United Kingdom, the speech was given by the British Prime Minister Neville Chamberlain, in Westminster, London.[1]
Battle of Britain The British officially recognise the battle's duration as being from 10 July until 31 October 1940, which overlaps the period of large-scale night attacks known as the Blitz, that lasted from 7 September 1940 to 11 May 1941.[18] German historians do not accept this subdivision and regard the battle as a single campaign lasting from July 1940 to June 1941, including the Blitz.[19]
