The confusion on April 3rd and 4th, 1941

Thing started to go badly with General Wavell's intervention, and then General Gambier-Parry, had ordered the 3rd Armoured Brigade to backtrack, giving the appearance of indecision. General Neame was out of touch with events, and was away from his headquarters. General O'Connor had arrived and issued orders in Neames' name. General O'Connor modified the withdrawal to the Er Regima-Tocra line. He wanted to use the 2nd Armoured Division to protect the Australian flank. Later in the day on April 4, the German reconnaissance unit reached Er Regiman, where they found the 2/13th Australian Battalion. The Australians were supported by the 51st Field Regiment, and drove off the Germans. This is based on the account in Vol.II of the Official History.
