text_A: On 4 April, Rommel was advised by his supply officers that fuel was running short, which could result in a delay of up to four days. The problem was Rommel's fault, as he had not advised his supply officers of his intentions, and no fuel dumps had been set up. Rommel ordered the 5th Light Division to unload all of their lorries and to return to El Agheila to collect fuel and ammunition. Driving through the night, they were able to reduce the halt to a single day. Fuel supply was problematic throughout the campaign, as no petrol was available locally; it had to be brought from Europe by tanker and then carried by road to where it was needed. Food and fresh water were also in short supply, and it was difficult to move tanks and other equipment off-road through the sand. Cyrenaica was captured by 8 April, except for the port city of Tobruk, which was besieged on 11 April.
text_B: Were the supply officers to blame for the lack of fuel?
NO.
