The memoirs of the last SS adjutant to Adolf Hitler are to be published in a move historians say could cast away the last shred of doubt over his personal involvement in the Holocaust.

Fritz Darges died at the weekend aged 96 with instructions for his manuscript about his time spent at the side of the Führer to be published once he was gone.

Darges was the last surviving member of Hitler's inner circle and was present for all major conferences, social engagements and policy announcements for four years of the war.

Experts say his account of his time as Hitler's direct link to the SS could discount the claims of revisionists who have tried to claim the German leader knew nothing of the extermination programme. Right-wing historians have claimed the planing for the murder of six million Jews was carried out by SS chief Heinrich Himmler.

Mainstream historians believe it inconceivable that Hitler did not issue verbal directives about the mass killings in Darges' presence. Other courtiers, such as armaments minister Albert Speer and propaganda chief Josef Goebbels, had their diaries published post war with no reference to hearing Hitler ordering the "Final Solution".

Darges died on Saturday still believing in the man who engineered the Jewish Holocaust as "the greatest who ever lived." His memoirs will be published now in accordance with his will.
