Later in the session, a pre-arranged deception was made to influence Chamberlain and exert negative pressure: one of Hitler`s assistants entered the room to inform Hitler that other Germans had been killed in Czechoslovakia, to which Hitler shouted in response: “I will avenge each of them. The Czechs must be annihilated.  The meeting ended with Hitler`s refusal to make concessions to the Allies` demands.  Later that evening, Hitler worried that he had gone too far to put pressure on Chamberlain and called the suite of Chamberlain`s hotel and said he would only agree to annex the Sudetenland without plans in other areas, provided that Czechoslovakia began evacuating ethnic Czechs from German-majority territories by September 26 at 8:00 a.m. .m. . . .
