Regierung Dönitz
By April, little was left of the armaments industry, and Speer had few official duties. Speer visited the "Führerbunker" on April 22 for the last time. He met Hitler and toured the damaged Chancellery before leaving Berlin to return to Hamburg. On April 29, the day before committing suicide, Hitler dictated a final political testament which dropped Speer from the successor government. Speer was to be replaced by his subordinate, Karl-Otto Saur. Speer was disappointed that Hitler had not selected him as his successor. After Hitler's death, Speer offered his services to the so-called Flensburg Government, headed by Hitler's successor, Karl Dönitz. He took a role in that short-lived regime as Minister of Industry and Production. Speer provided information to the Allies, regarding the effects of the air war, and on a broad range of subjects, beginning on May 10. On May 23, two weeks after the surrender of German forces, British troops arrested the members of the Flensburg Government and brought Nazi Germany to a formal end.
