Ridiculous. The Fuhrer was a war hero who risk his life many times and was wounded by a gas attack. He only became indecisive when he was forced to accept the fact that the Wehrmacht-especially the General staff- realized they were cut out of the decision process-so they began to appose and plot against him. All this came to head on July 20th 1944. Saying that he was 'delusional' just shows a lack of proper reading and research in which the internet plays no part. It is so easy to spot when someone is delusional because they can't understand just how bias the internet is. Also, not wanting to accept the fact that google is edited for political correctness-in which direction I need not to mention.
First, I would recommend General Walter Warlimont's long and complex work recalling the general staff and their anger-of which he commanded-"Inside Hitler's Headquarters" The fragments of the shorthand records taken during the twice daily military briefings are fascinating-to say the least. Here he describes the daily efforts of the general staff to deceive the Fuhrer in order to get the action they think is warranted.
In connection of Dunkirk he highlights the on going, seemingly endless, problems of moving the Wehrmacht and supplying it, that led to devastating problems in future battles. There was no political issues whatsoever in the Dunkirk fall back-it was a result of overbearing bureaucratized system and the general staff's attempts to 'influence' the Fuhrer by deceiving him. This was a daily attempt that went on the entire war ending with the 'Steiner attack' that was a total fabrication by the staff. Of course the internet paints it as the Fuhrer's 'ghost army's' when actually it was the staff that he hated.
"Inside Hitler's Headquarters" is for persons who already possess a good knowledge of the hierarchy in the system.
Sir Ian Kershaw- known as 'the knighted one' is the worlds scholar on the Fuhrer, although his hatred for America makes me ill, any of his dozen or so books are excellent.
