T.A. Gardner is right about having an important port to supply a very large Army. And Benghazi and Tobrouk weren't large enough. The British, in the other hand, had Alexandria.

And the main question here is that Rommel was not getting his supplies. Why? MALTA and ULTRA. Enough for a devastating defeat.
