Morell was one of the occupants of the Führerbunker, located in the garden of the Reich Chancellery, once Hitler and his entourage relocated there from the Wolf's Lair in Rastenburg in East Prussia. As the Battle of Berlin progressed and the outlook became dire, it was Morell who provided the cyanide capsules which Eva Braun would later use to kill herself, and which Joseph Goebbels and his wife Magda used to murder their six children before killing themselves.[27]
