A look at the German reoccupation of the Rhineland, explaining the background of this demilitarised zone set up under the Treaty of Versailles. The Rhineland had acted as a buffer between France and Germany, and the invasion therefore placed France under direct threat. The film raises the question of what Britain's response to this will be.
In pairs, students could make a prediction about how the British government would respond to the German occupation of the Rhineland. They could then share their ideas with the rest of the class.
