Adolf Hitler's personal cook described how the Nazi leader was a fussy eater who survived on millet and cake in his final days.

Letters by Constanze Manziarly, who was nicknamed Miss Marzipani by the SS, show how she was frightened and stressed in providing food to the Fuhrer, who had renounced meat in the 1930s.

The missives to her sister, found by researcher Stefan Dietrich in Innsbruck, Austria, told of how she lived in constant fear of Hitler's moods.

She wrote: "I am not exaggerating. I encounter unimaginable difficulties that I cannot report," she said.

The Mirror reported how she had been preparing and taking 'faddish' food to Hitler's mountain home in Berchtesgaden.

In April 1944, she wrote: "I have to stay as long as he is there. It is my cast-iron duty. But what makes me so worn out is the immense burden of responsibility I must bear with it."

She told her sister that "all resistance" to Hitler "is futile and would probably end up with me being in court" and described how he liked to eat millet or quark with linseed oil and, instead of meat, he would eat plates of chopped mushrooms.

In the letters, she would refer to him as the "chief doctor" and she cooked him a last supper on 30 April 1945 of fried eggs and mashed potatoes without realising that he had already killed himself. The final meal she cooked for him that he ate was pasta with tomato sauce, the Mirror reported.

She fled the bunker but was spotted being captured by two Red Army soldiers and was never seen again.
