JJ Chalmers and Raksha Dave tell the dramatic story of the events of September 1, 1939, which began the countdown to the beginning of World War II.

The events of September 2, 1939; German forces had been in Poland for more than 24 hours; anxiety builds across Britain.

In 1939 an ultimatum is made to Germany -- if Hitler did not respond, war would be declared; as soon as war began air raid sirens wailed and the first British casualties were recorded.
