Walmington-on-Sea is a fictional seaside resort that is the setting of Dad's Army during the Second World War, including the BBC Television sitcom (1968-1977), the BBC Radio 4 series and two feature films (1971 and 2016).
Walmington-on-Sea is on the south coast of England which, following the fall of France and the evacuation of the British Expeditionary Force from Dunkirk, found itself on the front line against Hitler. It is situated in Sussex[1] and the nearest large town is Eastbourne, where Captain Mainwaring was educated at the local grammar school.
The series followed the adventures and misadventures of members of a fictional platoon of the Home Guard - a (real) WWII volunteer army that was formed from those ineligible for conscription by age, minor physical inability or occupation, to defend the United Kingdom from German invasion following the fall of France.
