11:15 am, 3 September 1939. The nation gathers around their radios to hear Prime Minister Neville Chamberlain make the announcement they have feared for months: Britain is at war with Germany. Seventy years on from that historic day, this is the definitive history of the build-up to, outbreak & first few months of World War Two, from the events of early 1939, right through to the first war-time Christmas.
