The American historian William L. Shirer estimated in his “Rise and Fall of the Third Reich” (1960) that Czechoslovakia, although Hitler was not bluffing about its intention to invade, could have resisted considerably. Shirer believed that Britain and France had sufficient air defence to avoid severe bombing of London and Paris, and could have waged a swift and fruitful war against Germany.  He quotes Churchill as saying that the agreement means that “Britain and France are in a much worse position than Hitler`s Germany.”  After personally inspecting the Czech fortifications, Hitler privately told Joseph Goebbels that “we shed a lot of blood” and that it was fortunate that there had been no fighting.  Later in the meeting, a pre-arranged deception was made to influence and pressure Chamberlain: one of Hitler`s accomplices entered the room to inform Hitler of other Germans killed in Czechoslovakia, and Hitler then shouted: “I will avenge each of them. The Czechs must be destroyed.  The meeting ended with Hitler`s refusal to make concessions to the demands of the Allies.  Later that evening, Hitler was concerned that he had gone too far to put pressure on Chamberlain, and he called Chamberlain`s hotel suite to say that he would only accept the annexation of Sudetenland without plans in other areas, provided that Czechoslovakia began evacuating ethnic Chechens from the majority regions of Germany by 8 p.m. on September 26. After being pushed by Chamberlain, Hitler agreed to issue the ultimatum for October 1 (the same date on which Operation Green was to begin).  Hitler then told Chamberlain that it was a concession he wanted to make to the Prime Minister as a “gift”, out of respect for the fact that Chamberlain was prepared to back down a little from his previous position.  Hitler added that after the annexation of the Sudetenland, Germany would no longer have territorial rights over Czechoslovakia and would enter into a collective agreement to guarantee the borders of Germany and Czechoslovakia. On 28 September at 10 a.m., four hours before the deadline and without Hitler`s agreement at the request of Czechoslovakia, the British Ambassador to Italy, Lord Perth, summoned the Italian Foreign Minister, Galeazzo Ciano, to request an emergency meeting.  Perth informed Ciano that Chamberlain had ordered him to ask Mussolini in the negotiations and ask Hitler to delay the ultimatum.  At 11:00 a.m., Ciano met With Mussolini and informed him of Chamberlain`s proposal; Mussolini agreed and responded by questioning the Italian ambassador to Germany and telling him: “Go immediately to Fuhrer`s house and tell him that I will be by his side, but that I ask for a 24-hour delay before hostilities begin.
