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.
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.
[2] Those included a pleasure pier (filmed in Great Yarmouth[3]) with a 20-foot (6m) wide gap blown in the middle to prevent it from being used as a landing stage by invading armed forces.
In common with most real British towns, Walmington-on-Sea has a church, Saint Aldhelm's, with a hall next door which is the setting for various community events in the episodes such as the Christmas pantomime and a place for the Sea Scouts to parade.
The distinctive flint cottages in Thetford's Nether Row appeared in four episodes: "Man Hunt", "The Armoured Might of Lance Corporal Jones", "The Big Parade" and "Time on My Hands".
