Joshua Levine, one of our leading Second World War historians, talks to Harry Mount about the 85th anniversary of the Blitz - which began on September 7 1940.
Levine's book The Secret History of the Blitz led to him advising film director Steve McQueen for his 2024 film Blitz. 
His book Forgotten Voices of Dunkirk inspired Christopher Nolan to make Dunkirk (2017), for which Levine was the historical advisor.
