Thanks for the explanation onetrack!
We must have in mind that WW2 was the first really mechanised war and as with the tactics the logistics was quite different to the first war, wich probably had to be optimised through time.
The Germans invented the 'blitzkrieg' [flashwar] and might have foreseen the problems around logistics, however the invading armoured divisions easily lost contact with the essentiel fuel tankers wich should follow them.
The problems for US forces under their 'Island hopping', shows how difficult it is for the logistics to follow the development whilst no general would delay any opportunity due to the argument of spareparts being caught behind the frontline.
I have to admit that I'm quite sceptic around the British prepareness to the logistic problems. SS Thistelgorm wich should supply the british build-up in Egypt was sunk in the Red Sea. When later found it have become a much attractive diving-object, but what is interesting is the listing of the cargo where in between are lots of creates with wellingtons. Wellingtons for a desert battle is probably a good sign of the British logistics :-/
