The origins of the Second World War remain clouded in Churchillian mythology. Sixty years on, Peter Neville's controversial book provides an essential reassessment of the appeasement myths by examining a central yet understudied figure. Sir Nevile Henderson has been vilified as 'our Nazi Ambassador in Berlin' by historians and popular memory alike. He has remained in disgrace despite the widespread historical rethinking of appeasement in recent years. Yet there has never before been a book-length study of Henderson despite his central role as Britain's Ambassador. Peter Neville's important reassessment draws upon primary documents to overturn orthodox interpretations. While Henderson's analysis of the Nazi regime was seriously flawed, history has vastly overstated his influence. In presenting the first full and close analysis of what Henderson himself called 'the failure of a mission', the author has made a pathbreaking contribution to the history of appeasement.
