On 16 January 1945, following the Wehrmacht's defeat in the Battle of the Bulge, Schädle 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". The 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 briefcases, before personnel were allowed to pass into the corridor of the "Führerbunker" proper. By 23 April 1945, Schädle commanded approximately 30 members of the unit who stood guard for Hitler until his suicide on 30 April 1945. During that time, the remaining FBK and RSD men had been withdrawn from the "exposed sentry posts" on the Chancellery roof and outside the "Führerbunker" entrances due to the shelling of the area by Soviet Red Army artillery.
