Hitler refused to listen to the advice of subordinate commanders, eg Battle of Stalingrad in 1943, Hitler refused to allow his 6th Army to strategically retreat. Force of 200,000 men were defeated- contributed to defeat on EF. During D-Day German panzer divisions failed to respond quickly because Hitler was asleep- nobody dared wake him for permission. Loyalty to Nazis was viewed more important than being quality- Goring remained in charge of Luftwaffe despite bad leadership at Dunkirk/Battle of Britain/Stalingrad
