The mystery surrounding Hitler's death involves an escape plan devised during the final stages of World War II. In early 1945, Hitler was nearly in despair but was unwilling to accept defeat. He concocted an escape plan known as 'Operation Greenland,' hoping to flee to Greenland via seaplane. This little-known secret was revealed by former German military researcher Ernst Konig, who was involved in the plan. Although the operation ultimately failed due to the siege of Berlin, Hitler and Eva Braun took their own lives in the bunker of the Reich Chancellery. However, doubts about whether Hitler truly committed suicide persist. From dental records to blood analysis and rumors of his escape, these clues intertwine, leaving the mystery of Hitler's life and death still unresolved.
