(7) There is a right to vote in and out of the transferred territories, the possibility to exercise within six months from the date of this agreement. A German-Czechoslovakian commission defines the terms of the option, examines the possibilities of facilitating the transmission of the population and resolves the fundamental issues arising from this transfer. Meanwhile, the British government has asked Benea to ask for 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.   As the threats of Germany and a European war became increasingly evident, opinions changed. Chamberlain was awarded for his role as one of the “Men of Munich” in books such as the Guilty Men of 1940. A rare defence of the wartime accord came in 1944 from Viscount Maugham, who had been the Lord`s chancellor. Maugham regarded the decision to establish a Czechoslovakian state with large German and Hungarian minorities as a “dangerous experiment” in the face of previous disputes and described the agreement, which stemmed mainly from the need for France to free itself from its contractual obligations in the face of its vagueness to war.  After the war, Churchill`s memoirs of that time, The Gathering Storm (1948), claimed that Chamberlain`s appeasement of Hitler had been wrong in Munich, and noted Churchill`s pre-war warnings about Hitler`s plan of attack and Britain`s folly of disarmament after Germany reached air parity with Britain.
