On a wet afternoon in September 1938, Neville Chamberlain stepped off an aeroplane and announced that his visit to Hitler had averted the greatest crisis in recent memory. It was, he later assured the crowd in Downing Street, 'peace for our time'. Less than a year later, Germany invaded Poland and the Second World War began.

Drawing on previously unseen sources, Appeasing Hitler sweeps from the advent of Hitler in 1933 to the beaches of Dunkirk, and presents an unforgettable portrait of the ministers, aristocrats and amateur diplomats whose actions and inaction had devastating consequences.
