On 16 January 1945, following the Wehrmacht's defeat in the Battle of the Bulge, Misch and the rest of Hitler's personal staff moved into the "Führerbunker" and "Vorbunker" under the Reich Chancellery garden in Berlin. His FBK commanding officer, Franz Schädle, appointed Misch to be the bunker telephone operator. Misch handled all of the direct communication from the bunker. He did not leave it for any significant period of time until the war ended in May 1945. On 22 April 1945, Schädle called him on the phone and told him there was a place reserved for his wife and young daughter on one of the last planes out of Berlin. Misch was temporarily released from duty and drove to pick up his family to take them to the aircraft. However, his wife refused to take their daughter and leave him and her parents in Berlin. Upon returning to the Reich Chancellery, Misch learned that Hitler was releasing most of the remaining staff to leave Berlin. By that date, as the Red Army was entering Berlin, propaganda minister Joseph Goebbels and his wife Magda brought their six young children to stay in the "Vorbunker". Joseph Goebbels moved into the room next to Misch's telephone exchange in the lower level of the "Führerbunker". The Goebbels children would play in the corridor around Misch's post.
