Sandbag defences and barbed wire are quickly put up around the heart of London.
Unused / unissued material - dates unclear or unknown.
Various shots of British soldiers moving sandbags to place them around vulnerable buildings. Sand bag emplacements are built at the entrance to Downing Street. Barbed wire, sandbags and other defences are built around another government building. People have their passes checked.
Various shots of young men in civvies, possibly new recruits. They are filling bags with straw. They appear to be in some kind of billets or barracks.
More shots of defences being built around London. Good shots of troops fixing up barbed wire fences. Some of the civilians walking past look curiously at the defences.
