This is a frank account of the initial period of the war seldom reminisced over by World War Two documentaries or individuals remembering the allies most successful operations.
The episode covers key moments that led to the escalation of conflict, such as the Nazi invasion of Poland, the Scandinavian campaigns of the Soviets in Finland and Nazis in Norway, and the response of the Chamberlain government in Britain.
Similarly to the first episode there are a number of fascinating interviews where individuals like Lt-Col Sir Martin Lindsay and Robert Boothby give first hand accounts into the political climate at the time and encounters with the likes of Chamberlain, Halifax, and Churchill.
Outside of the politics the evacuation of civilians in Britain is seen from interesting perspective, particularly the psychological effects upon children that are discussed in the interview of children's care organiser Lucy Faithful.
There are also some amusing moments that I can relate to stories told by my grandparents about the universally despised air-raid wardens and the popular songs of George Formby.
It all leads to a turning point in the leadership of Britain and its role in the war.
Some of the editing of historical footage could have been a bit sharper, but it is overall a fantastic production and Lawrence Oliver's narration is splendid once more.
It's a 9.5/10 for me but I round upwards.
