Hitler's Wartime Conversations : His Personal Thoughts as Recorded by Martin Bormann

After dinner at the Wolfs Lair it was Hitlers custom to retire to his private quarters where Hitler and his entourage often listened to gramophone records of Beethoven symphonies, selections from Wagner while Hitler would hold forth with lengthy and rambling monologues touching on a wide variety of subjects. Hitler was invariably joined by Keitel and his two secretaries, also present was Martin Bormann who decided to commission a recording of Hitlers words for posterity.
