Dismayed by the betrayal of his Western allies, President Benes resigned on 5 October 1939 and soon fled to London, where he inserted a government in exile. At the First Prize of The Viennese, in November 1938, Germany and Italy ceded Czechoslovakia to Hungary via southern Slovakia and southern Ruthenia, while Poland took over the city, Tén and its surroundings, as well as two regions of northern Slovakia. On 22 September Chamberlain flew again to Germany and met Hitler in Bad Godesberg, where he learned with dismay that Hitler had exacerbated his demands: he now wanted the Sudetenland to be occupied by the German army and for the Czechoslovaks to be evacuated from the area until 28 September. Chamberlain agreed to submit the new proposal to the Czechoslovaks, who rejected it, as did the British cabinet and the French. On the 24th, the French ordered a partial mobilization; The day before, the Czechoslovakians had ordered a general mobilization. Since Czechoslovakia was one of the best equipped armies in the world at that time, it was able to mobilize 47 divisions, 37 of which were for the German border, and the most mountainous line on this border was strongly fixed. On the German side, the final version of “Case Green”, as approved by Hitler on 30 May, showed 39 divisions for operations against Czechoslovakia. The Czechoslovaks were ready to fight, but they could not win alone. 29-30 September 1938: Germany, Italy, Great Britain and France sign the Munich Agreement by which Czechoslovakia must cede its border and defensive regions (the so-called Sudetenland) to Nazi Germany. German troops occupied these territories between 1 and 10 October 1938. Under the Munich Agreement, the entire territory, mainly German, was to be returned to Czechoslovakia by 10 October. Poland and Hungary occupied other parts of the country and, after a few months, Czechoslovakia ceased to exist and what was left of Slovakia became a German puppet state.
In mid-September, Chamberlain offered to go to Hitler`s exercises in Berchtesgaden to discuss the situation personally with the Fuhrer. Hitler agreed not to take military action without further discussion and Chamberlain agreed to convince his cabinet and the French to accept the results of a referendum in the Sudetenland. Daladier and his Foreign Minister, Georges-Etienne Bonnet, then went to London, where a joint proposal was drawn up for all regions with more than 50% Sudeten Germans to be transferred to Germany. Czechoslovakians were not consulted. The Czechoslovakian government initially rejected the proposal, but had to adopt it on 21 September. While France and the United States relied on the prevention of wars, Britain supported the emergency of the Sudeten Germans. Czechoslovakia was heavily dependent on the support of Great Britain and France, but it did not. On the contrary, Britain and France urged Czechoslovakia to yield to the demands of the Sudeten Germans.
However, the Czechoslovakian government should not be incriminated. Czechoslovakian President Edvard Beneé even mobilized the army. Because the Germans wanted the Western powers to abandon the Czechs, they published in the press in August, the same month that Germany deployed 750,000 soldiers along the Czechoslovakian border.
