On September 28 at 10 a.m., four hours before the deadline expired and without Czechoslovakia`s agreement, the British ambassador to Italy, Lord Perth, called Italian Foreign Minister Galeazzo Ciano to request an urgent meeting.  Perth informed Ciano that Chamberlain had ordered him to invite Mussolini to begin negotiations and to urge Hitler to postpone the ultimatum.  At 11:00 a.m., Ciano Mussolini met with him and informed him of Chamberlain`s proposal; Mussolini agreed and responded by phoning the Italian ambassador to Germany and telling him: “Go immediately to the Führer and tell him that whatever happens, I will be at his side, but that I ask for a delay of twenty-four hours before the hostilities begin. In the meantime, I will study what can be done to solve the problem.  Hitler received Mussolini`s embassy during discussions with the French ambassador. Hitler told the ambassador: “My good friend, Benito Mussolini, asked me to postpone the marching orders of the German army for twenty-four hours, and I agreed. This was obviously not a concession, since the date of the invasion was set for October 1, 1938.  In an interview with Chamberlain, Lord Perth Mussolini thanked Chamberlain and Chamberlain`s request to ask Mussolini to participate on September 29 in a quadrilateral conference of the United Kingdom, France, Germany and Italy in Munich in order to resolve the Sudetenland problem before the 2:00 p.m. deadline. Mussolini agreed.  Hitler`s only demand was to have Mussolini involved in the conference negotiations.  As U.S. President Franklin D. Roosevelt learned that the conference was scheduled, he telegraphed Chamberlain: “Good Man.”  The economic consequences of the Munich Agreement will inevitably be very severe for Czechoslovakia.
The loss of industries, railways, nodes, etc. cannot help but cause heavy commercial losses and unemployment. There is also no doubt that Czechoslovakia will become the object of quasi-colonial exploitation for Germany. Under the Munich Agreement, the entire territory of Czechoslovakia was to be handed over by 10 October. Poland and Hungary occupied other parts of the country, and after a few months Czechoslovakia ceased to exist and what remained of Slovakia became a German puppet state. The agreement on the annexation of the Sudetenland by Germany was signed on September 29, 1938. Later, at the meeting, a pre-agreed deception was undertaken to influence Chamberlain and exert pressure: one of Hitler`s accomplices entered the room to inform Hitler that other Germans had been killed in Czechoslovakia, to which Hitler shouted in response: “I will avenge each and every one of them. The Czechs must be destroyed.  The meeting ended with Hitler`s refusal to make concessions on Allied claims.  Later that evening, Hitler worried that he had gone too far to put pressure on Chamberlain and called the chamberlain hotel suite to say that he would agree to annex only the Sudetenland without any plans in other areas, provided that Czechoslovakia began evacuating ethnic Czechs from the German majority by September 26 at 8:00 a.m.
