Hitler greets British PM Neville Chamberlain, at the start of the Munich Conference

A deal was reached on 29 September, and at about 1:30 am on 30 September 1938, Adolf Hitler, Neville Chamberlain, Benito Mussolini and Édouard Daladier signed the Munich Agreement. The agreement was officially introduced by Mussolini although in fact the so-called Italian plan had been prepared in the German Foreign Office. It was nearly identical to the Godesberg proposal: the German army was to complete the occupation of the Sudetenland by 10 October, and an international commission would decide the future of other disputed areas.

Czechoslovakia was informed by Britain and France that it could either resist Nazi Germany alone or submit to the prescribed annexations. The Czechoslovak government, realizing the hopelessness of fighting the Nazis alone, reluctantly capitulated (30 September) and agreed to abide by the agreement. The settlement gave Germany the Sudetenland starting 10 October, and de facto control over the rest of Czechoslovakia as long as Hitler promised to go no further. On 30 September after some rest, Chamberlain went to Hitler and asked him to sign a peace treaty between the United Kingdom and Germany. After Hitler's interpreter translated it for him, he happily agreed.
