When Germany invaded Poland in 1939, Britain and France declared war. This ended the British government's appeasement policy. Includes Neville Chamberlain’s radio broadcast from 3 September 1939, announcing that a state of war existed between Britain and Germany.

The film sums up study of the road to war and can introduce study of the war itself. Students could look back at the step by step progress to war and discuss where they themselves would have declared war. Challenge the class to base their decisions on knowledge and opinion of the time, avoiding hindsight.
