During the Munich Crisis of 1938, when Hitler threatened to invade Czechoslovakia, Prime Minister Neville Chamberlain visited Nazi Germany three times in an attempt to avert war.
On 30 September he returned to Heston Aerodrome with an agreement which removed the imminent threat, while allowing Hitler to annexe parts of Czechoslovakia. He brandished a statement signed by the two leaders which said the agreement was “symbolic of the desire of our two peoples never to go to war with one another again”. Speaking at Downing Street a short while later he said it promised “peace for our time”. This optimism was short lived, as the Munich Agreement was broken within a year and Britain went to war over the Nazi invasion of Poland.
