when did great britain declare war on germany ww2
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 Historian Stephen Bungay cited Germany's failure to destroy Britain's air defences to force an armistice (or even outright surrender) as the first major German defeat in World War II and a crucial turning point in the conflict.[23] The Battle of Britain takes its name from a speech by Winston Churchill to the House of Commons on 18 June: "What General Weygand has called The Battle of France is over. The Battle of Britain is about to begin."[24]
