The story of the devastating air raids on a Yorkshire city in the Second World War will be told in a BBC TV programme tonight.
Dig 1940: The Blitz starts in Somerset where Jules Hudson and his team try to recover the remains of a German bomber shot down on a raid on Bristol during WW2.
They then travel to Hull to meet witnesses of the Blitz which left 95 per cent of houses damaged or destroyed.
Historian Ron Fairfax, who contributed to the programme, said a Government D-notice preventing the identity of the port and the severity of the damage being known had far-reaching consequences, including the city continuing to have some of the poorest housing in the country into the 1970s.
The programme is on BBC 1 at 7.30pm.
