Rommel decided that he needed to move faster, if he was to be able to engage any British troops

The British were withdrawing so fast, by April 4th, Rommel decied that he needed to move faster. The 3rd reconnaissance Unit had reached Benghazi, before daylight on 4 April. Visiting in person, Rommel ordered them to head for Mechili, when the Brescia Division arrived. Rommel already was using kampfgruppes as his main organizational unit. There were all-arms units composed of men and equipment from multiple traditional units. He sent Graf Schwerin to Tmimi. He sent the Fabris group (from the Ariete Division) to Mechili. He sent General Streich to Tobruk. He had the 8th MG Battalion, a 5th Panzer Regiment squadron, and an anti-tank company. Lt-Col. Olbrich, with the majority of the 5th Panzer Regiment, 2nd MG Battalion, field artillery, and an Ariete tank battalion, was sent towards Msus, with the eventual goal of either Mechili or Timimi, depending on developments. The units were becoming scattered, and Graf Schwerin's group needed refueling. thy were near Ben Gania. This is based on the account in Vol.II of the Official History.
