A Flying bomb incident, showing bomb damage to houses in Guernsey Grove, with Anderson shelters in the foreground, 24 July 1944.

Although V1 flying bombs were intended for Central London, a British government disinformation campaign led to most of them falling in South London, well short of their targets.

A total of 95 V1s fell in Lambeth killing 250 people and severely injuring a further 709.

The Anderson shelters appear to have survived the incident more or less intact and were felt by many to offer more protection than the communal surface shelters.
