In September, Chamberlain flew to Berchtesgaden to negotiate directly with Hitler, hoping to avoid war. Hitler now demanded that the Sudetenland should be absorbed into Germany, convincing Chamberlain that refusal meant war. Chamberlain, with France, told the Czech president that he must hand to Germany all territory with a German majority. Czechoslovakia would thus lose 800,000 citizens, much of its industry and its mountain defences in the west. In effect, the British and French pressed their ally to cede territory to a hostile neighbour to prevent annihilation.
Hitler then informed Chamberlain that Germany was about to occupy the Sudetenland and that the Czechoslovaks had to move out. The Czechoslovaks rejected the demand, as did the British and the French. Mussolini persuaded Hitler to put the dispute to a four-power conference. Czechoslovakia was not to be a party to these talks. On 29 September, Hitler, Chamberlain, Édouard Daladier (the French Prime Minister) and Mussolini met in Munich. They agreed that Germany would complete its occupation of the Sudetenland, but an international commission would consider other disputed areas. Czechoslovakia was told that if it did not submit, it would stand alone. At Chamberlain's request, Hitler signed a peace treaty between the United Kingdom and Germany. Chamberlain returned to Britain promising "peace for our time". In March 1939, Chamberlain foresaw a possible disarmament conference between himself, Daladier, Hitler, Mussolini and Joseph Stalin; his home secretary, Samuel Hoare, said, "These five men, working together in Europe and blessed in their efforts by the President of the United States of America, might make themselves eternal benefactors of the human race."[12] That month, Czechoslovakia ceased to exist, divided among Germany, Hungary, Poland, and an independent Slovakia.
