That was the whole concept behind the Blitzkrieg in general, it was never limited to Rommel and the African campaign. As an Australian and a ex military officer I am quiet aware of the African Campaign, the siege of Tobruk is second only to the Gallipoli landings in terms of importance to Australian Military Culture.
Thus I know that the initial push by Rommel took advantage of circumstance more then anything, as he pushed far past his planned advance due to a combination of British forces having been weakened to reinforce the Greek front, and a reluctance of the British forces to engage as they over estimated the German forces strength. Rommel took advantage and harried their retreat, which prevented them from reforming and building defensive works, resulting in a surprising fast advance.
My bad then. I also realized how I had made my post into a personal attack, and made some edits. I hope I can apologize for my rude tone.
