1/2. The Battle of Britain was Hitler's first and possibly most important defeat. It defined the course of the Second World War, forcing him to make a series of decisions that guaranteed his own destruction. In this two-part series, we'll trace this monumental story from the dark days of the defeat of France, through to the triumph of RAF Fighter Command in the skies above Britain.

In Part 1, Dan takes us from the total defeat of the Allied armies on the European mainland through to the all-out air assault in the skies above Britain. He shares the exhilarating stories of pilots in their iconic fighter planes and outlines the crucial factors that would turn the tide in favour of the Allies.

Written and produced by Dan Snow, and edited by Dougal Patmore.
