Gate. However, Hitler refused to leave Berlin. On 26 April 1945, the improvised landing strip was used by Hanna Reitsch to fly in Colonel-General Robert Ritter von Greim, appointed by Hitler as head of the Luftwaffe after Hermann Göring's dismissal. During the evening of 28 April, Reitsch flew von Greim out on the same road-strip to Plön. On 29 April 1945, the Soviet Red Army launched an all-out attack on the centre of Berlin. The Soviet artillery opened up with intense fire in and around the Reich Chancellery area. That evening in the bunker complex below the Chancellery garden, Hitler said his farewell to his personal pilots, Baur and Betz. Baur pleaded with Hitler to leave Berlin. The men volunteered to fly Hitler out of Germany in a Ju 390 and to safety. It was in vain as Hitler turned Baur down, stating he had to stay in Berlin. Baur stayed in the bunker complex until Hitler killed himself on the afternoon of 30 April. After Hitler's suicide, Baur found the improvised road-strip too pot-holed for use and overrun by the Soviet 3rd Shock Army. A plan was devised to escape out from Berlin to the Allies on the western side of the Elbe or to the German Army to the North. SS-Brigadeführer Wilhelm Mohnke split up the Reich Chancellery and Führerbunker soldiers and personnel into ten main groups. Baur, Betz and Martin Bormann left the Reich Chancellery as part of one of the groups. During the escape attempt, Baur was shot in the legs, and the wound was so serious that his right lower leg was later amputated in Posen on 10 June 1945, while a Soviet prisoner-of-war. Baur was of great interest to his captors, who believed he might have flown Hitler to safety before the fall of Berlin. They also believed he had information concerning stolen art, specifically about the plundering of the Amber Room (Bernsteinzimmer) in Leningrad. He was taken to the Soviet Union and imprisoned there for ten years before being released on 10 October 1955. The French then imprisoned him until 1957. Later life and book Baur returned to West Germany and in 1957 wrote his autobiography Ich flog die Mächtigen der Erde (literally "I flew the mighty of the Earth"). Later, a lengthened version was published as Mit Mächtigen zwischen Himmel und Erde ("Between Heaven and Earth with the Mighty"). The French translation
