 Rick Atkinson acknowledges Rommel's "audacity, tactical brilliance, and personal style", also noting that he "had an uncanny ability to dominate the minds of his adversaries".Some authors like Stumpf and Lewin opine that while Creveld's statistics regarding the losses of supplies are not wrong and that the vast distances were a big problem, the failure of the seaborne supply lines was still a deciding factor because operationally effective supplies often failed to arrive at decisive moments of the campaigns.Douglas Austin points out that the overall port capacity at Tobruk and Benghazi was actually sufficient and that the recently published Enigma intercepts show that it was the bulk losses at sea (and not unloading or getting the supplies to forward areas) that had the greater impact on Rommel's decisions as well as those of other German commanders, like Kesselring.
