During World War II, British Prime Minister Churchill, who rejected the agreement when it was signed, decided that the terms of the agreement would not be met after the war and that the Sudenian regions should be returned to post-war Czechoslovakia. On 5 August 1942, Foreign Minister Anthony Eden sends the following note to Jan Masaryk: 29–30 September 1938: Germany, Italy, the United Kingdom and France sign the Munich Agreement, according to which Czechoslovakia must cede its border regions and defence zones (the so-called Sudetenland region) to Nazi Germany. German troops occupied these territories between 1 and 10 October 1938. [still] An agreement signed at the Munich Conference in September 1938 ceded the German-speaking Sudetenland of Czechoslovakia to Germany. The agreement was concluded between Germany, Italy, Great Britain and France. .
