On Saturday 7th September 1940, the Luftwaffe broke thro' the defences of fighter command and set London alight.

Over 635 tonnes of high explosives and at least 800 bombs fell on the capital. Over 400 Londoners were killed, and a further 16,000 were injured.

The photo is of a hospital in south-east London that was hit.

This was the result of a V2 rocket attack in Croydon. The old man in the photo lost everything. Among the civil workers at the bombsite was PC Godwin from Gypsey Hill station.

His daughter tells the story: 'My father told me that he was trying to console the old man, who was in a state of shock. Apparently he had gone out for a walk to the local with his dog while his wife cooked the midday Sunday dinner.

'When he returned the whole street had been demolished and most of the people were under the debris including the man's wife. My father had got the man a cup of tea and talked to him while they searched for his wife.'

That's a sad story, and was repeated many, many times.
