May 1940 is one of the critical months in British history. As the Nazis tore across Europe and Winston Churchill became Prime Minister, our guest Sinclair McKay explains that this was also the month in which the Home Guard was founded.

Originally known as the Local Defence Volunteers (LDV) and affectionately recalled in the BBC sitcom as 'Dad's Army', the Home Guard was a colourful military force that was compounded by individuals from the local community.

In this episode McKay takes us back to the first year of this colourful organisation's existence. He describes how Churchill was involved in the development of the Home Guard's identity and how an inspiring woman, Edith Summerskill, sought to shape it.
