On 13 September, after the arrival of violence and internal unrest in Czechoslovakia, Chamberlain asked Hitler to meet face-to-face to find a solution to avoid war.  Chamberlain arrived in Germany on 15 September by plane, then came to Hitler`s residence in Berchtesgaden for a meeting.  Henlein flew to Germany on the same day.  On that day, Hitler and Chamberlain held talks in which Hitler insisted that the Sudeten Germans should be able to exercise the right to national self-determination and join the Sudetenland with Germany. Hitler also expressed his concern to Chamberlain about what he considered British “threats.”  Chamberlain replied that he had not made “threats” and asked Hitler, frustrated: “Why did I come here to waste my time?”  Hitler replied that if Chamberlain was willing to accept the self-determination of the Sudeten Germans, he would be willing to discuss it.  Chamberlain and Hitler had three hours of discussions, and the meeting was interrupted. Chamberlain returned to the UK and met with his firm to discuss the matter.  The Munich critics never surprised me the least. I probably should have been part of the criticism if I hadn`t been responsible. But there were two or three reflections that the same criticisms should take into account. On the one hand, they criticised the bad and bad date in criticizing the establishment of Munich.
They should have criticised the inability of successive governments and all parties to foresee the need for rearmament in light of what is happening in Germany; And the correct date on which the critics should have been attached was in 1936, when the German reshuffle of the Rhineland was observed, in defiance of the provisions of the treaty. December 1938, 97.32% of adults donated to the NSDAP. About half a million Sudeten Germans joined the NSDAP, 17.34% of the German population in the Sudetenland (the average participation of the NSDAP in Nazi Germany was 7.85%). Thus, the Sudetenland was the “pro-Nazi” region of the Third Reich.  In the meantime, the British government has asked Benea to request a mediator. As he did not want to sever his government`s relations with Western Europe, the heirs reluctantly agreed. The British appointed Lord Runciman, the former Liberal cabinet minister, who arrived in Prague on 3 August to convince Benes to accept an acceptable plan for the Sudeten Germans.  On 20 July, Bonnet informed the Czechoslovakian ambassador in Paris that France, while publicly declaring its support for the Czechoslovakian negotiations, was not prepared to go to war on the Sudetenland.  In August, the German press was full of stories of Czechoslovakian atrocities against the Sudeten Germans, with the intention of forcing the West to put pressure on the Czechoslovakians to make concessions.  Hitler hoped that the Czechoslovaks would refuse and that the West would feel morally justified in abandoning the Czechoslovaks to their fate.
 In August, Germany sent 750,000 troops along the border with Czechoslovakia, officially as part of military maneuvers.   On September 4 or 5, Erbe presented the fourth plan, which met almost all of the requirements of the agreement. The Sudeten Germans were invited by Hitler to the prairies to avoid compromise, and the SdP organized demonstrations which, on 7 September, provoked a police operation in Ostrava, during which two of its deputies were arrested.  The Sudeten Germans used the incident and the false allegations of other atrocities as a pretext to interrupt further negotiations.   The British public expected an imminent war, and Chamberlain`s “statesman`s gesture” was initially applauded.
