true.
Dunno about Dunkirk. If Hitler was like he claimed to be then racism was high on his agenda and he wouldn't want to wipe his racial opponents out.
His writiings wrre all about attacking the Russians who he thought inferior (he'd never been).
I've been studying him because we have lots of film fotage whereas other in history in war/chess:) dont really exist.
I think you are correct on the feel of the word armhow, but logistics means supplies and never strategy nor tactics.
I really mean logistic Hluek. The reason why the the Brits were able to escape from Dunkirk because Germans Panzer group stretched too far in their advance. This depleted their supplies for battle. Their lorries were not able to catch up with them. They have to wait for a day or two for replenishment enabling the Brits and its allies escaped from captivity. They failed to calcualte well this factor when they laid their plans beforehand their attack.
