By early 1945, Germany's military situation was on the verge of total collapse. In January 1945, Rattenhuber accompanied Hitler and his entourage into the bunker complex under the Reich Chancellery garden in the central government sector of Berlin. The FBK and the rest of Hitler's personal staff moved into the "Vorbunker" and "Führerbunker". FBK and RSD men were stationed outside the "Führerbunker" entrances. Main entry into the "Führerbunker" was from a stairway built at right angles leading down from the "Vorbunker". After descending the stairs into the lower section, RSD and FBK men were positioned in a guard room to check identity cards and search briefcases, before personnel were allowed to pass into the corridor of the "Führerbunker" proper.
